Chemical bath deposition was used to prepare antimony trisulfide (Sb 2 S 3 ) thin films, of different particle size and with noticeably different band gaps, onto glass substrates. The structural investigations revealed that the as-deposited films are amorphous in nature. The particle size determined from the intercept…

Using density functional theory the atomic and electronic structure of sodium are predicted to depart substantially from those expected of simple metals for $r_s <$ 2.48 ($p > 130$ GPa). Newly-predicted phases include those with low structural symmetry, semi-metallic electronic properties (including zero-gap semicondu…

High molecular weight cyclic alpha-1,4-glucan (referred to as cycloamylose) exhibited an artificial chaperone property toward three enzymes in different categories. The inclusion properties of cycloamylose effectively accommodated detergents, which keep the chemically denatured enzymes from aggregation, and promoted p…

The tribological properties of two smooth surfaces in the presence of a thin confined film are investigated with a generic model for the interaction between two surfaces and with computer simulations. It is shown that at large normal contact pressures, an ultra thin film automatically leads to static friction between…

Pyrrole and aniline solutions were mixed in different ratios and oxidized under anodic conditions on Pt surface in protic medium. The electrocopolymerization and electrochemical properties of these alloys were investigated. Current-potential diagrams of polyaniline (PA), polypyrrole (PP) and the resulting alloys were…

Multidomain samples of ferroics (ferroelectrics, ferroelastics, and related materials) with fixed geometrical distribution of domains can offer new macroscopic properties required for particular applications. Two extreme cases of such applications are defined. In domain-geometry-engineered samples of ferroic crystals,…
