IMPACT OF CHEMICAL HETEROGENEITY Design of surfaces using SAMs provides a hitherto unexplored approach to experimentally understand the effects of chemical heterogeneity of surfaces on polymer adsorption.[27,28] It is well known that millimeter- or micrometer-sized patterns in self-assembled monolayers can be created using techniques such as UV photooxida-tion, microcontact printing, and micromachining.[29] However, these patterns […]
INTRODUCTION Many important physical properties of natural or man-made aerosol particles such as light scattering, electrostatic charges, and toxicity, as well as their behavior involving physical processes such as diffusion, condensation, and thermophoresis, depend strongly on their size distribution. An important aerosol behavior mechanism affecting the size distribution of aerosol particles is coagulation. Aerosol particles […]
