Affinity membrane was used for the endotoxin adsorption. The matrix macropore membrane was prepared from filterpaper by chemically crosslinking, and polymyxin B was immobilized as affinity ligand. The prepared membrane cartridge can be used for the removal of endotoxin from aqueous solutions. With a cartridge of 40 sheets affinity membrane containing, the endotoxin level of the processed solution can be reduced to a minimum of 4 pg/mL.

Self-organization processes in semiconductor materials on the example of nanostructuring of por-Si at long anodic etching of p-type Si in the electrolyte with internal source of the current are shown. in conditions of a “soft” etching of the Si point defects are formed and in the subsequently occurs their spatial-temporal ordering. This leads to the ordering pores and the nanostructuring of por-Si. Self-organization mechanism of Si nanocrystallites islets is described by the effects of the elastically-deformative, defectively-deformative and capillary-fluctuation forces.

The increasing demand in the diverse device applications of transparent conducting oxides （TCOs） requires synthesis of new TCOs of n- or p-type conductivity. This article is about materials engineering of ZnO-SnO2- in2O3-Ga2O3 to synthesize powders of the quaternary compound Zn2-xSn1-xlnxGaxO4-δ in the stoichiometry of x = 0.2, 0.3, and 0.4 by solid state reaction at 1275℃. Lattice parameters were determined by X-ray diffraction （XRD） technique and solubility of in3＋ and Ga3＋ in spinel Zn2SnO4 was found at 1275℃. The solubility limit of in3＋ and Ga3＋ in Zn2SnO4 is found at below x = 0.4. The optical transmittance approximated by the UV-Vis reflectance spectra showed excellent characteristics while optical band gap was consistent across 3.2 eV with slight decrease along increasing x value. Carrier mobility of the species was considerably higher than the older versions of zinc stannate spinel co-substitutions whereas the carrier concentrations were moderate.

ion-plasma sputtering and codeposition of ultrafine Ta and Cd particles on a moving substrate were used to prepare the solid solutions, in particular, the alloys with up to 66.2 at.% Cd in the form of coatings. in vacuum heat treatment cadmium evaporates at 700°C from cadmium based solid solutions resulting in formation of a porous tantalum with a highly developed surface. The prepared tantalum-based materials assume the technological application of the investigation results.

WE have applied the differential display (D. D.) of mRNA method to detect and clone tran-scripts that were differentially expressed between rice NiLs (Near-isogenic lines) H7R (resis-tant) and H7S (susceptible) which were induced by Magnaporthe grisea. The cDNA gene-tags obtained from D. D. analysis were reamplified by PCR and screened by Southern
