Soil drying and re-wetting (DRW) occurs at varying frequencies and intensities during crop production, and is deliberately used in water-saving irrigation techniques that aim to enhance crop water use efficiency. Soil drying not only limits root water uptake which can (but not always) perturb shoot water status, but also alters root synthesis of phytohormones and their transport to shoots to re...

We report a study of the wetting and ordering of thermotropic liquid crystal (LC) droplets that are trapped (or "caged") within micrometer-sized cationic polymeric microcapsules dispersed in aqueous solutions of surfactants. When they were initially dispersed in water, we observed caged, nearly spherical droplets of E7, a nematic LC mixture, to occupy ∼40% of the interior volume of the polymeri...

A self-consistent field approach is used to investigate the partial to complete wetting transition for an A:B polymer blend at coexistence where polymers A and B have equal numbers of segments, N. The surface free energy, Fs , is modeled using the quadratic form suggested by Schmidt and Binder J. Phys. II France 46, 1631 1985 , namely, Fs 1 0.5g 1 , where and g are the surface equivalents of th...

It is not clear how various wetting agent products affect moisture distribution throughout sand-based putting green rootzones. The objective of this research was to determine how localized dry spot (LDS) incidence, and soil moisture values and uniformity were affected by the application of five commercially available wetting agents. Wetting agents were applied during the 2008 growing season and...

In this review, we analyze the structure of multicomponent alloys without principal components (they are also called high entropy alloys—HEAs), containing not only metals but hydrogen, nitrogen, carbon, boron, or silicon. particular, discuss phenomenon grain boundary (GB) wetting by melt solid phase. The GB can be complete incomplete (partial). former case, grains matrix completely separated co...
