This new text offers experienced students a comprehensive review of available techniques for the remote sensing of aerosols. These small particles influence both atmospheric visibility and the thermodynamics of the atmosphere. They are also of great importance in any consideration of climate change problems. Aerosols may also be responsible for the loss of harvests, human health problems and ecological disasters. Thus, this detailed study of aerosol properties on a global scale could not be more timely.

This book experimentally investigates the angular light scattering properties of three atmospherically relevant particles: ice crystals, dust particles and secondary organic aerosol particles. Key optical quantities under examination are the near-backscattering depolarisation properties and the angular light scattering function. The main question is how these parameters are related to the particle microphysical properties, such as particle size and complexity.

Colloid and Interface Science, Vol. II: Aerosols, Emulsions, and Surfactants presents papers from the International Conference on Colloids and Surfaces held in San Juan, Puerto Rico on June 21-25, 1976. The book discusses topics on aerosols, emulsions, and surfactants. The text includes papers on the evaluation of the classical theory of nucleation using expansion chamber measurements of the homogeneous nucleation rate of water from the vapor; and the effect of friction-reducing substances on the droplet size distribution from spray nozzles. The rotational relaxation of the Brownian motion; the calculations of unipolar aerosol charging; and the electrochemical measurements in nonionic microemulsions are also encompassed. The book further discusses the structure of microemulsions containing nonionic surfactants; the interactions of surfactants with proteins; and the solubilization of vitamin K and folic acid by micelle-forming surfactants.

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.

Optical particle s1z1ng is undoubtedly a fascinating field of research of the utmost practical importance. In the Universe fluids are nearly everywhere, and when they occur they almost invariably contain particles. Inside our bodies we can take the example of blood transporting a vi tal procession of red and white cells. Around us, we can find various particles in the air we breathe, bubbles in the champagne or the soda we drink, or natural and artificial (polluting!) particles in the lakes we swim in. Industrial processes and systems are also concerned with particles, from pulverized coal flames to fluidized beds, in a range of applications involving rocket exhausts, pneuma tic transport and more generally the infinite realm of mul tiphase situations. Such an obviously vast field would require a whole volume like this one merely to attempt to describe it superficially. To be sure, we would need a scientific Prevert to catalogue such an endless inventory. Finally, even outside our terrestrial spaceship particles can be detected in alien atmospheres or between stars. Theorists will enjoy analyzing the richness of light/particle interact. ion, a subject which is very far from being exhausted. Experimental researchers will love designing and studying various probing instruments with a laser source at the input and a computer at the output, two requisites of today' s technological revolution.

Although man's environment, from the interstellar dust to the earth beneath his feet, is composed to a large extent of finely divided material, his knowledge of the propert ies of such materials is surprisingly slight. For many years the scientist has accepted that matter may exist as solids, liquids or gases although the dividing line between the states may often be rather blurred; this classification has been upset by powders, which at rest are solids, when aerated may behave as liquids, and when suspended in gases take on some of the properties of gases. It is now widely recognized that powder technology is a field of study in its own right. The industrial applications of this new science are far reaching. The size of fine particles affects the properties of a powder in many important ways. For example, it determines the setting time of cement, the hiding power of pigments and the activity of chemical catalysts; the taste of food, the potency of drugs and the sintering shrink age of metallurgical powders are also strongly affected by the size of the particles of which the powder is made up. Particle size measurement is to powder technology as thermometry is to the study of heat and is in the same state of flux as thermometry was in its early days. Only in the case of a sphere can the size of a particle be completely described by one number.
