Conventional wetting theories on rough surfaces with Wenzel, Cassie-Baxter, and Penetrate modes suggest the possibility of tuning the contact angle by adjusting the surface texture. Despite decades of intensive study, there are still many experimental results that are not well understood because conventional wetting theory, which assumes an infinite droplet size, has been used to explain measur...

Poly (lactic-co-glycolic) acid microspheres are amenable to a number of biomedical procedures that support delivery of cells, drugs, peptides or genes. Hydrophilisation or wetting of poly (lactic-co-glycolic) acid are an important pre-requisites for attachment of cells and can be achieved via exposure to plasma oxygen or nitrogen, surface hydrolysis with NaOH or chloric acid, immersion in ethan...

Wetting phenomena are ubiquitous in nature and technology. A solid substrate exposed to the environment is almost invariably covered by a layer of fluid material. In this review, the surface forces that lead to wetting are considered, and the equilibrium surface coverage of a substrate in contact with a drop of liquid. Depending on the nature of the surface forces involved, different scenarios ...

Loess and loess-like soils, when exposed to water, lose their strength characteristics, physical mechanical properties change original structure. The stress-strain state is transformed in these soils wetted. Therefore, the problem of building on loess studying mechanisms subsidence relevant. In this article, we consider determining stress soil stratum under its own weight a limited wetted area....

The use of simple plasma treatments and polymer deposition to tailor the anisotropic wetting properties of one-dimensional (1D) submicrometer-scale grooved surfaces, fabricated using interferometric lithography in photoresist polymer films, is reported. Strongly anisotropic wetting phenomena are observed for as-prepared 1D grooved surfaces for both positive and negative photoresists. Low-pressu...

If new heavier W ’e and/or Z’s are discovered at the SSC, only partial information on their couplings to quarks and leptons can be obtained by studying their decays into electrons and muons. In particular, without polarired beams, one cannot distinguish between heavy W ’s which have left-handed (WL) or right-handed (W,) couplings to all fermions. Here, we study the r decays of WL and W, and com...
