Contact photolithography was used to fabricate three-layer polymeric waveguide structures with transverse dimensions of 50 × 90 μm on the basis of two photopolymerizing methacrylate compositions with different refractive indices. The optical loss on the wavelength of 632.8 nm was 0.37 ± 0.14 dB cm-1. This loss is mostly due to the light scattering by the material of the waveguide layer produced by bulk polymerization. © S.P.

A new method of microchannel formation in silicone rubber cured by heat in the presence of a platinum catalyst was developed using whiskers of p-aminobenzoic acid. Four types of whiskers with lateral dimensions of 10-20, 50-70, 200-300, and 500-600 μm and lengths of 2-3, 5-10, 10-20, and 20-30 mm, respectively, were grown from hot aqueous solutions. A new method for the manufacture of elastic siloxane rubber samples penetrated by open channels with the size corresponding to the size of whiskers is presented. The materials were studied by optical and atomic force microscopy, powder X-ray diffraction, differential scanning calorimetry, gas chromatography - mass spectrometry, and porosimetry. © 2015 Springer Science+Business Media New York.

An experimental scheme for studying laser-produced plasmas under extremal conditions with the aid of a compound refractive X-ray lens has been implemented. Laser-produced plasma bunches have been imaged in hard X-rays upon intense laser irradiation of a copper foil target. © 2015, Pleiades Publishing, Ltd. Source
