What is ATOMIC EMISSION SPECTROSCOPY? What does ATOMIC EMISSION SPECTROSCOPY mean? ATOMIC EMISSION SPECTROSCOPY meaning - ATOMIC EMISSION SPECTROSCOPY definition - ATOMIC EMISSION SPECTROSCOPY explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Atomic emission spectrometry (AES) is a method of chemical analysis that uses the intensity of light emitted from a flame, plasma, arc, or spark at a particular wavelength to determine the quantity of an element in a sample. The wavelength of the atomic spectral line gives the identity of the element while the intensity of the emitted light is proportional to the number of atoms of the element. A sample of a material (analyte) is brought into the flame as either a gas, sprayed solution, or directly inserted into the flame by use of a small loop of wire, usually platinum. The heat from the flame evaporates the solvent and breaks chemical bonds to create free atoms. The thermal energy also excites the atoms into excited electronic states that subsequently emit light when they return to the ground electronic state. Each element emits light at a characteristic wavelength, which is dispersed by a grating or prism and detected in the spectrometer. A frequent application of the emission measurement with the flame is the regulation of alkali metals for pharmaceutical analytics. Inductively coupled plasma atomic emission spectroscopy (ICP-AES) uses an inductively coupled plasma to produce excited atoms and ions that emit electromagnetic radiation at wavelengths characteristic of a particular element. Advantages of ICP-AES are excellent limit of detection and linear dynamic range, multi-element capability, low chemical interference and a stable and reproducible signal. Disadvantages are spectral interferences (many emission lines), cost and operating expense and the fact that samples typically must be in a liquid solution. Spark or arc atomic emission spectroscopy is used for the analysis of metallic elements in solid samples. For non-conductive materials, the sample is ground with graphite powder to make it conductive. In traditional arc spectroscopy methods, a sample of the solid was commonly ground up and destroyed during analysis. An electric arc or spark is passed through the sample, heating it to a high temperature to excite the atoms within it. The excited analyte atoms emit light at characteristic wavelengths that can be dispersed with a monochromator and detected. In the past, the spark or arc conditions were typically not well controlled, the analysis for the elements in the sample were qualitative. However, modern spark sources with controlled discharges can be considered quantitative. Both qualitative and quantitative spark analysis are widely used for production quality control in foundry and metal casting facilities.

As photonic circuits grow in complexity, full quantum tomography becomes impractical, and therefore an efficient method for their characterization is essential. Here we propose and demonstrate a fast, reliable method for reconstructing the two-photon state produced by an arbitrary quadratically non-linear optical circuit.

What is Zero-point energy?, Explain Zero-point energy, Define Zero-point energy

~~~ Zero-point energy ~~~ Title: What is Zero-point energy?, Explain Zero-point energy, Define Zero-point energy Created on: 2018-10-07 Source Link: https://en.wikipedia.org/wiki/Zero-point_energy ------ Description: Zero-point energy is the difference between the lowest possible energy that a quantum mechanical system may have, and the classical minimum energy of the system. Unlike in classical mechanics, quantum systems constantly fluctuate in their lowest energy state due to the Heisenberg uncertainty principle. As well as atoms and molecules, the empty space of the vacuum has these properties. According to quantum field theory, the universe can be thought of not as isolated particles but continuous fluctuating fields: matter fields, whose quanta are fermions , and force fields, whose quanta are bosons . All these fields have zero-point energy. These fluctuating zero-point fields lead to a kind of reintroduction of an aether in physics, since some systems can detect the existence of this energy. However this aether cannot be thought of as a physical medium if it is to be Lorentz invariant such that there is no contradiction with Einstein's theory of special relativity.Physics currently lacks a full theoretical model for understanding zero-point energy; in particular the discrepancy between theorized and observed vacuum energy is a source of major contention. Physicists Richard Feynman and John Wheeler calculated the zero-point radiation of the vacuum to be an order of magnitude greater than nuclear energy, with a single light bulb containing enough energy to boil all the world's oceans. Yet according to Einstein's theory of general relativity any such energy would gravitate and the experimental evidence from both the expansion of the universe, dark energy and the Casimir effect show any such energy to be exceptionally weak. A popular proposal that attempts to address this issue is to say that the fermion field has a negative zero-point energy while the boson field has positive zero-point energy and thus these energies somehow cancel each other out. This idea would be true if supersymmetry were an exact symmetry of nature. However, the LHC at CERN has so far found no evidence to support supersymmetry. Moreover, it is known that if supersymmetry is valid at all, it is at most a broken symmetry, only true at very high energies, and no one has been able to show a theory where zero-point cancellations occur in the low energy universe we observe today. This discrepancy is known as the cosmological constant problem and it is one of the greatest unsolved mysteries in physics. Many physicists believe that "the vacuum holds the key to a full understanding of nature". ------ To see your favorite topic here, fill out this request form: https://docs.google.com/forms/d/e/1FAIpQLScU0dLbeWsc01IC0AaO8sgaSgxMFtvBL31c_pjnwEZUiq99Fw/viewform ------ Source: Wikipedia.org articles, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license.

IEEE AP/MTT/EMC/ED Turkey Seminars - Prof. Ekmel Özbay, January 5, 2018
 
47:42
Speaker: Prof. Ekmel Özbay, Nanotechnology Research Center, Bilkent University Topic: “Metamaterial based nanobiosensors and nanophotodetectors” Location: Middle East Technical University, Ankara, Turkey Abstract: In this talk, we will present how metamaterials can be used for nanobiosensors and nanophotodetector applications. Our results show that a plasmonic structure can be successfully applied to bio-sensing applications and extended to the detection of specific bacteria species. A highly tunable design for obtaining double resonance substrates to be used in Surface Enhanced Raman Spectroscopy will also be presented. Surface Enhanced Raman Scattering experiments are conducted to compare the enhancements obtained from double resonance substrates to those obtained from single resonance gold truncated nano-cones. We will present a UV plasmonic antenna integrated metal semiconductor metal (MSM) photodetector based on GaN. We also report the design, fabrication, and measurement of a device comprising a split ring resonator array on epitaxial graphene. We obtained resonance broadening and tuning of split ring resonators by utilizing an epitaxial graphene transistor with transparent top-gate. Metallic split ring resonator (SRR) structures are used in nanophotonics applications in order to localize and enhance incident electromagnetic field. Electrically controllable sheet carrier concentration of graphene provides a platform where the resonance of the SRRs fabricated on graphene can be tuned. The reflectivity spectra of SRR arrays shift by applying gate voltage, which modulates the sheet carrier concentration, and thereby the optical conductivity of monolayer graphene. We experimentally and numerically demonstrated that the tuning range can be increased by tailoring the effective mode area of the SRR and enhancing the interaction with graphene. Bio: Prof. Dr. Ekmel Ozbay received M.S. and Ph. D. degrees from Stanford University in electrical engineering, in 1989 and 1992. He worked as a postdoctoral research associate in Stanford University and he worked as a scientist in Iowa State University. He joined Bilkent University (Ankara, Turkey) in 1995, where he is currently a full professor in Physics Department and EEE Department. In 2003, he founded Bilkent University Nanotechnology Research Center (NANOTAM) where he leads a research group working on nanophotonics, nanometamaterials, nanoelectronics, GaN/AlGaN MOCVD growth, and GaN based devices. He is the 1997 recipient of the Adolph Lomb Medal of OSA and 2005 European Union Descartes Science award. He worked as an editor for Nature Scientific Reports, Optics Letters, PNFA, and IEEE JQE journals. He has published 430+ articles in SCI journals. His papers have received 13500+ SCI citations with an SCI h-index of 55. He has given 145+ invited talks in international conferences.

This is an audio version of the Wikipedia Article: Mössbauer spectroscopy Listening is a more natural way of learning, when compared to reading. Written language only began at around 3200 BC, but spoken language has existed long ago. Learning by listening is a great way to: - increases imagination and understanding - improves your listening skills - improves your own spoken accent - learn while on the move - reduce eye strain Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone. You can find other Wikipedia audio articles too at: https://www.youtube.com/channel/UCuKfABj2eGyjH3ntPxp4YeQ In case you don't find one that you were looking for, put a comment. This video uses Google TTS en-US-Standard-D voice. SUMMARY ======= Mössbauer spectroscopy is a spectroscopic technique based on the Mössbauer effect. This effect, discovered by Rudolf Mössbauer (also Moessbauer, German: "Mößbauer") in 1958, consists in the nearly recoil-free, resonant absorption and emission of gamma rays in solids. Like nuclear magnetic resonance spectroscopy, Mössbauer spectroscopy probes tiny changes in the energy levels of an atomic nucleus in response to its environment. Typically, three types of nuclear interactions may be observed: isomer shift, also called chemical shift in the older literature; quadrupole splitting; and magnetic hyperfine splitting (see also the Zeeman effect). Due to the high energy and extremely narrow line widths of gamma rays, Mössbauer spectroscopy is a very sensitive technique in terms of energy (and hence frequency) resolution, capable of detecting changes in just a few parts per 1011.

Study of Shroud Of Turin Says the Burial Cloth Is Authentic
 
06:11
In 2013, Professor Giulio Fanti and journalist Saverio Gaeta published a book with the results of some chemical and mechanical tests which confirm that the Shroud of Turin dates back to the 1st century. From an article by Andrea Tornielli of Rome regarding the 2013 tests: "The research includes three new tests, two chemical ones and one mechanical one. The first two were carried out with an FT-IR system, one using infra-red light and the other using Raman spectroscopy. The third was a multi-parametric mechanical test based on five different mechanical parameters linked to the voltage of the wire. The machine used to examine the Shroud's fibres and test traction, allowed researchers to examine tiny fibres alongside about twenty samples of cloth dated between 3000 BC and 2000 AD. "Final results show that the Shroud fibres examined produced the following dates, all of which are 95% certain and centuries away from the medieval dating obtained with Carbon-14 testing in 1988: the dates given to the Shroud after FT-IR testing, is 300 BC ±400, 200 BC ±500 after Raman testing and 400 AD ±400 after multi-parametric mechanical testing. The average of all three dates is 33 BC ±250 years. "The tests were carried out using tiny fibres of material extracted from the Shroud by micro-analyst Giovanni Riggi di Numana who passed away in 2008 but had participated in the1988 research project and gave the material to Fanti through the cultural institute Fondazione 3M." (End of quote) In 2011, a scientific study of the Shroud of Turin said the shroud was "created by flash of supernatural light: It couldn't be a medieval forgery." The article discussed in the video can be found here: http://www.dailymail.co.uk/sciencetech/article-2076443/Turin-Shroud-created-flash-supernatural-light.html?ITO=1490. I also liked the article here: http://www.longislandpress.com/2011/12/22/shroud-of-turin-study-says-shroud-real/ For more about the problems with the Carbon 14 dating of the Shroud, please see: https://www.youtube.com/watch?v=QFxijCLPr_4 Muslim Arif Khan at Revelaion and Rationality blog brought up the following about the Shroud of Turin: "Why is it so hard to explain the image? There are specific key characteristics of the image that any theory must account for: 1. The image is a photographic negative 2. There is a 3D property to the image -- the further away a part of the body was from the cloth the fainter that part appears 3. The image is visible only in the very upper fibres of the cloth -- it does not go all the way through to the back of the cloth 4. When standing close to the cloth the image is not visible -- it is only visible when standing a few metres away from the cloth 5. The blood flows on the cloth have been shown to be 100% anatomically correct based on modern physiology 6. There are no pigments or dyes used on the cloth 7. The blood is human and contains extractable DNA samples It is very hard to put together a theory that can satisfy all of the above items." For Christians, our hope, joy, and peace is in the resurrection, and the Shroud of Turin is physical evidence of that event. So, if you're struggling to find your peace and joy, think on the Resurrection of Jesus and all that it means for you.

He discovered that when light traverses a transparent material, some of the deflected light changes wavelength. This phenomenon, subsequently known as Raman scattering, results from the Raman effect. In 1954, India honoured him with its highest civilian award, the Bharat Ratna.

Fifth harmonic generator 213 nm - sales@dmphotonics.com

Fifth harmonic generator 213 nm - [email protected] Featured research group: Krypton tagging velocimetry of an underexpanded jet. Abstract In this work, we present the excitation/emission strategy, experimental setup, and results of an implementation of krypton tagging velocimetry (KTV). KTV is performed as follows: (i) seed a base flow with krypton; (ii) photo-synthesize metastable krypton atoms with a frequency-doubled dye laser to form the tagged tracer; (iii) record the translation of the tagged metastable krypton by imaging the laser-induced fluorescence (LIF) that is produced with an additional dye laser. The principle strength of KTV, relative to other tagging velocimetry techniques, is the use of a chemically inert tracer. KTV results are presented for an underexpanded jet of three mixtures of varying Kr∕N 2 concentration. It is demonstrated that KTV can be used in gas mixtures of relatively low krypton mole fraction (0.5% Kr/99.5% N 2), and the KTV data from that experiment are found to be in good agreement with an empirical fit found in the literature. We find that KTV is useful to perform instantaneous velocity measurements with metastable krypton as a chemically inert, dilute, long-lifetime tracer in gas-phase flows.

INTRODUCTIONVelocimetry techniques for use in high-speed wind-tunnel facilities are of interest to study flow fields for the purposes of thermal/fluids science and test and evaluation. These investigations are intended to further the understanding of the fundamental flow physics that influence macro-scale behavior of test articles. Researchers have developed various forms of velocimetry techniques; for examples, see the handbook edited by Tropea et al. [1]. In that handbook, there is a chapter [ 2] that describes the basics of tagging velocimetry. The methodology of tagging velocimetry is similar to observing the translation of a dye that has been introduced to a fluid; the dye is used as a tracer in the fluid and observed at prescribed times . In tagging velocimetry of gas-phase flows,the tracer is a native, seeded, or synthesized gas. Typically, fluorescence of the tracer is induced to provide spatial information at prescribed times so that velocity may be obtained.In this work, we present metastable krypton as a candidate tracer for tagging velocimetry. First, we motivate the use of Krby reviewing the characteristics of tracers that have been reported in the literature. Then, we present the krypton excitation/ emission strategy, experimental setup, and results of an implementation of krypton tagging velocimetry (KTV) as applied to an underexpanded jet of three mixtures. Finally, the KTV results are reduced and compared to an appropriate correlation of historical data.2. REVIEW OF EXISTING GAS-PHASE TRACERS Different constituents can be used as the tagging medium in high-speed gas flows. Important characteristics of tracers included: lifetime, reactivity, intensity of fluorescence, and ease of seeding/synthesis and excitation.Oxygen may be used as an unseeded tracer in air and O2 flows or possibly partially dissociated CO2 flows. The Raman excitation plus laser-induced electronic fluorescence (RELIEF) technique [3–7] utilizes vibrationally excited O2 as a tracer, and has a lifetime that is a function of the vibrational relaxation time. Researchers report the use of a dye laser and an ArF laser to implement RELIEF. Other researchers have used oxygen as a tracer by photochemically creating ozone, photodissociatingthe ozone to form O2, and imaging laser-induced fluorescence (LIF) from the O2[8–10]. The ozone tracer is reported to have a lifetime on the order of seconds.Nitrogen can be used as an unseeded tracer in air and N2 flows. In Michael et al. [11], the tracer was created by nonlinear excitation and dissociation of nitrogen with a femtosecond laser. Spatial information is recorded by imaging the emission of the recombining nitrogen atoms. In that work, researchers report an effective tracer lifetime on the order of 10 μs. Nitric oxide (NO) is an attractive candidate as a tracer for reasons including its long lifetime (order 1 –10 ms in the absence of polyatomic molecules) and ease of in situ production/seeding. https://www.researchgate.net/publication/277394483_Krypton_tagging_velocimetry_of_an_underexpanded_jet

The internal "electrodeless lamp" or "induction light" is a gas discharge lamp in which the power required to generate light is transferred from outside the lamp envelope to the gas inside via an electric or magnetic field, in contrast with a typical gas discharge lamp that uses internal electrodes connected to the power supply by conductors that pass through the lamp envelope. There are three advantages to elimination of the internal electrodes: Two systems are described below – plasma lamps, which use electrostatic induction to energize a bulb filled with sulfur vapor or metal halides, and fluorescent induction lamps, based upon a conventional fluorescent lamp bulb in which current is induced by an external coil of wire via electrodynamic induction. In 1705, the scientist Francis Hauksbee demonstrated that in a rotating glass globe with internal vacuum like in a barometer, filled with mercury, and statical charged by holding a hand against the rotating globe, a light phenomenon occurred, so bright that one could read a paper. Nikola Tesla demonstrated wireless transfer of power to electrodeless lamps in his lectures and articles in the 1890s, and subsequently patented a system of light and power distribution on those principles. In 1967 and 1968, John Anderson of General Electric applied for patents for electrodeless lamps. In 1971, Fusion UV Systems installed a 300-watt electrodeless microwave plasma UV lamp on a Coors can production line. Philips introduced their "QL" induction lighting systems, operating at 2.65 MHz, in 1990 in Europe and in 1992 in the US. Matsushita had induction light systems available in 1992. Intersource Technologies also announced one in 1992, called the "E-lamp". Operating at 13.6 MHz, it was to be available on the US market in 1993.

~~~ Centrosymmetry ~~~ Title: What is Centrosymmetry? Explain Centrosymmetry, Define Centrosymmetry, Meaning of Centrosymmetry Created on: 2018-10-04 Source Link: https://en.wikipedia.org/wiki/Centrosymmetry ------ Description: In crystallography, a point group which contains an inversion center as one of its symmetry elements is centrosymmetric. In such a point group, for every point in the unit cell there is an indistinguishable point . Such point groups are also said to have inversion symmetry. Point reflection is a similar term used in geometry. Crystals with an inversion center cannot display certain properties, such as the piezoelectric effect. The following space groups have inversion symmetry: the triclinic space group 2, the monoclinic 10-15, the orthorhombic 47-74, the tetragonal 83-88 and 123-142, the trigonal 147, 148 and 162-167, the hexagonal 175, 176 and 191-194, the cubic 200-206 and 221-230.Point groups lacking an inversion center can be polar, chiral , both or neither. A polar point group is whose symmetry operations leave more than one common point unmoved. A polar point group has no unique origin because each of those unmoved points can be chosen as one. The unmoved points collectively make a unique anisotropic axis. Polar point groups in crystal include 1, 2, 3, 4, 6, m, mm2, 3m, 4mm, and 6mm. A chiral point group is one containing only proper rotation symmetry. No inversion, reflection, roto-inversion or roto-reflection symmetry exists in such point group. Chiral point groups in crystal include 1, 2, 3, 4, 6, 222, 422, 622, 32, 23, and 432. Chiral molecules such as proteins crystallize in chiral point groups. Non-centrosymmetric point groups in crystal 1, 2, 3, 4, 6 are both polar and chiral. Non-centrosymmetric point groups in crystal -4, -42m, -6, -6m2, -43m are neither polar nor chiral. On the other hand, polar and chiral point groups must be non-centrosymmetric. ------ To see your favorite topic here, fill out this request form: https://docs.google.com/forms/d/e/1FAIpQLScU0dLbeWsc01IC0AaO8sgaSgxMFtvBL31c_pjnwEZUiq99Fw/viewform ------ Source: Wikipedia.org articles, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license.

Webinar: Contact Resonance Tools for AFM Nanomechanics
 
01:01:10
Nanoscale information on mechanical properties is critical for many advanced materials and nanotechnology applications. Atomic Force Microscopy techniques for probing mechanical properties of samples in the nanometer range have emerged over the past decades. In contrast to the large number of techniques for softer samples, few techniques are capable of measuring moduli in the 1-200 GPa range. One technique, Contact Resonance (CR), has proven to work very well in this range. CR methods operate in contact mode with dynamic excitation near a cantilever resonant frequency, enabling sensitive measurements over a wide range of materials. Moreover, analysis of the CR peak frequency and quality factor yields accurate, quantitative data on elastic modulus and viscoelastic damping. In this webinar, we'll explain the basic concepts of measurements with different CR approaches including: • Point spectroscopy • Qualitative contrast imaging • Quantitative mapping We'll also discuss practical implementation of contact resonance to a variety of samples and some of the pitfalls and artifacts you might encounter. Finally, we'll present results on how CR methods have been used to improve understanding of systems such as: • Composites • Thin films • Biomaterials • Polymer blends The nanomechanical characterization capabilities of CR methods, as you will come to learn, are an essential tool for the development, production, and in-situ monitoring of today's and tomorrow's materials. This webinar was first present live on June 26, 2013 by Dr. Donna Hurley and Dr. Roger Proksch. Donna Hurley Dr. Hurley leads the AFM Nanomechanics Project in the Material Measurement Laboratory at the National Institute of Standards & Technology (NIST) in Boulder, CO. Her project team creates and applies AFM measurement technology for material-property characterization. For over 10 years, she has developed contact resonance AFM modes for quantitative nanomechanical imaging. She is author or co-author of numerous technical articles, including chapters in the recently released Scanning Probe Acoustic Techniques (Springer-Verlag, 2012) and the upcoming SPM in Industrial Applications: Nanomechanical Characterization (John Wiley & Sons, 2013). She has a Ph.D. in Physics from the University of Illinois at Urbana-Champaign. Prior to NIST, she worked at GE Corporate Research (Schenectady, NY) and the University of Nottingham (UK). Roger Proksch Dr. Proksch is President and co-founder of Asylum Research, an Oxford Instruments company. He has over 20 years of AFM experience. He has co-authored many papers and is a co-inventor on numerous AFM patents. He received his Ph.D. from the University of Minnesota.
