Abstract BACKGROUND: Poly(1‐amino‐2‐naphthol‐4‐sulfonic acid) and its copolymers with aniline are a new class of conducting polymers which can acquire intrinsic protonic doping ability, leading to the formation of highly soluble self‐doped homopolymers and copolymers. Free OH and NH 2 groups in the polymer chain can…

Embossing or embedding of nanoparticles into a polymeric film is realized by an electromagnetic field. Upon laser light illumination nanoparticles absorb energy, convert it to heat, and sink into a locally softened polymer film as probed by atomic force microscope. The polymeric matrix forms a characteristic rim and s…

In this paper, some technological problems (e.g. low drawability, high susceptibility to galling, spring-back) occurring in the sheet-titanium forming process are discussed. A numerical simulation of the stamping process was carried out with the Adina System v.8.3 based on the finite element method. The effects of fri…

Ga 1− x Mn x As nanowires were synthesized with finely controlled Mn contents ( x = 0, 0.01, 0.02, 0.03, and 0.05) by the vapor transport method. They consisted of single-crystalline GaAs nanocrystals (avg. diameter = 60 nm) grown along the [111] direction. The Mn doping decreases the lattice constant, most significan…

We present an approach where biomolecular self-assembly is used in combination with lithography to produce patterns of metallic nanoparticles on a silicon substrate. This is achieved through a two-step method, resulting in attachment of nanoparticles on desired sites on the sample surfaces, which allowed a detailed ch…

Abstract In this paper, a semi‐classical one‐dimensional (1D) electron fluid model is built that is based on a classical two‐dimensional electron fluid theory taking into account electron–electron repulsive forces, which are significant in 1D system. We have used 1D fluid model to characterize the carbon nanotube (CNT…

Recent research has highlighted the ability of hydrolytically degradable electrostatic layer-by-layer films to act as versatile drug delivery systems capable of multi-agent release. A key element of these films is the potential to gain precise control of release by evoking a surface-erosion mechanism. Here we sought t…

Control of the nucleation rate is important for the growth of high quality protein crystals; therefore, the development of improved growth methods is required. Crystal growth with an external electric field is an attractive method for control of the nucleation rate. However, mainly a decrease in nucleation rate was ob…
