Available in PDF, EPUB and Kindle. Book excerpt: It has been thirty years since one of the authors (EJD) began a collaboration with Professor Milton Kerker at Clarkson University in Potsdam, New York using light scattering methods to study aerosol processes. The development of a relatively short-lived commercial particle levitator based on a modification of the Millikan oil drop experiment attracted their attention and led the author to the study of single droplets and solid microparticles by levitation methods. The early work on measurements of droplet evaporation rates using light scattering techniques to determine the size slowly expanded and diversified as better instrumentation was developed, and faster computers made it possible to perform Mie theory light scattering calculations with ease. Several milestones can be identified in the progress of single microparticle studies. The first is the introduction of the electrodynamic balance, which provided more robust trapping of a particle. The electrodynamic levitator, which has played an important role in atomic and molecular ion spectroscopy, leading to the Nobel Prize in Physics in 1989 shared by Wolfgang Paul of Bonn University and Hans Dehmelt of the University of Washington, was easily adapted to trap microparticles. Simultaneously, improvements in detectors for acquiring and storing light scattering data and theoretical and experimental studies of the interesting optical properties of microspheres, especially the work on morphology dependent resonances by Arthur Ashkin at the Bell Laboratories, Richard Chang, from Yale University, and Tony Campillo from the Naval Research Laboratories in Washington D. C.

Download or read book Optical Effects Associated with Small Particles written by Peter W. Barber and published by World Scientific. This book was released on 1988 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is a collection of review articles by scientists who have pioneered many of the recent advances in studies of the optical effects of small particles. The book begins with a review of the multitude of sharp dielectric resonances which exist in all optical spectra as a result of particle size and shape. Latest advances in absorption and fluorescence spectroscopy of a single particle and/or an ensemble of particles are also discussed, as well as advances in the energy transfer mechanisms for molecules embedded in the particle. The effects of laser-induced heating on a single particle are reviewed in terms of the hydrodynamics and thermodynamics of the liquid droplet and its ambient gas surrounding. The limits of applying bulk optical constants to small particles which lie between the bulk substance and the quantum-sized substance are also presented.

Download or read book Raman Capabilities for Aerosol Characterization written by Richard K. Chang and published by . This book was released on 1980 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemical speciation of microparticles can be achieved by spectral and intensity analyses of the inelastically scattered radiation (Raman and fluorescence). However, quantitative results by purely optical methods are intimately related to the environment with which the particles are in contact and the morphology of the microstructures. Morphology characterization of regularly shaped microparticles (spheres, cylinders, and spheroids) can be obtained by measuring the peaks in the extinction and elastically scattering spectra. Our investigation on the viability of quantitative species identification of molecules within a microparticle by inelastic laser scattering involved studies of the following: (1) dielectric and metal substrate interface to increase the intensity of the scattered radiation; and (2) morphology dependent dielectric resonances which can modify the scattering spectra.

Download or read book Laser Optics of Condensed Matter written by J. Birman and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Third Binational USA-USSR Symposium titled "Laser Optics of Con densed Matter" was held in Leningrad 1 June - 5 June 1987. This volume con tains the full text of 64 papers presented at (or prepared for) the Symposium in both plenary and poster sessions. This Symposium reestablished the very productive series of "Light Scattering" Binational Symposia which were initi ated in Moscow in 1975. Unfortunately there was an eight-year hiatus follow ing the Second Symposium in New York (1979). This interval, caused by serious chilling of the climate of USA-USSR collaboration, deprived the active scien tists on both sides of the opportunity to meet and interact in the active format of a conference. During this eight year interval there has been very rapid and intense development of scientific activity in the general area of laser optics phe nomena. The development of ultrafast laser sources has permitted rapid advances in time resolved spectroscopy and ultrafast processes; the field of optical bistability and strong nonlinearity became a hot topic; and intense work is now underway to clarify ideas of photon localization. These new dev elopments complement many advances in the study of low dimensional systems such as surfaces, new work on phase transitions, and novel studies of elemen tary excitations such as polariton-excitons in localized environments such as quantum wells and heterojunctions.

Download or read book Chemistry of Multiphase Atmospheric Systems written by Wolfgang Jaeschke and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 773 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rapidly increasing interest in the problems of air pollution and source-receptor relationships has led to a significant expansion of knowledge in the field of atmospheric chemistry. In general the chemistry of atmospheric trace constituents is governed by the oxygen content of the atmosphere. Upon entering the atmosphere in a more or less reduced state, trace substances are oxidized via various pathways and the generated products are often precursors of acidic compounds. Beside oxidation processes occurring in the gas phase, gaseous compounds are often converted into solid aerosol particles. The various steps within gas-to-particle conversion are constantly interacting with condensation processes, which are caused by the tropospheric water content. Thus in addition to the gaseous state, a liquid and solid state exists within the troposphere. The solid phase consists of atmospheric conversion products or fly ash and mineral dust. The liquid phase consists of water, conversion products and soluble compounds. The chemistry occurring within this system is often referred to as hydrogeneous chemistry. The chemist interprets this term, however, more strictly as reactions which occur only at an interphase between phases. This, however, is not always what happens in the atmosphere. There are indeed heterogeneous processes such as reactions occurring on the surface of dry aerosol particles. But apart from these, we must focus as well on reactions in the homogeneous phase, which are single steps of consecutive reactions running through various phases.
