cu-mo and cu-ti contact structures were fabricated on multi-crystalline silicon substrates to provide a low resistance ohmic contact. deposition steps are done in an excellent vacuum chamber by means of electron beam evaporation and samples are then annealed for the realization of an efficient alloy layer. the effects of process parameters such as film thickness, annealing duration and temperat...

Here multiple angle of incidence ellipsometry was successfully applied to in situ assess the contact angle and surface coverage of gold nanoparticles as small as 18 nm, coated with stimuli-responsive polymers, at water-oil and water-air interfaces in the presence of NaCl and NaOH, respectively. The interfacial adsorption of the nanoparticles was found to be very slow and took days to reach a fa...

– If deposited on a hydrophobic rough substrate, a small drop of water can look like a pearl, with a contact angle close to 180. We examine the conditions for observing such a phenomenon and show practical achievements where the contact angle can be predicted and thus quantitatively tuned by the design of the surface microstructure. Presentation. – The contact angle of a drop on a solid is idea...

Emergency department visits due to dermatologic disease is quite rare. Euphorbia helioscopia is a widely distributed plant in rural areas. E. helioscopia related contact dermatitis (Irritant contact dermatitis or allergic contact dermatitis) are known however only a few case reported in literature. We are reporting on three patients with contact dermatitis from E. helioscopia. Irritant contact ...

We report a new methyltrimethoxysilane (MTMS) based route to growing a Janus silica film at the oil–water interface, which upon drying shows anisotropic wetting by water on its two surfaces. The contact angle of water on the surface grown in contact with the oil-side is found to be 150 , but it is much smaller, 65 , on the side which grew in contact with the aqueous phase. This large difference...
