Based on regular porous polymeric membranes, the synthesis of metallic and dielectric spearhead structures with given morphological characteristics was carried out. Copper structures with 1 μm height and dielectric spearhead microstructures made of iodoic acid with 12 μm height and 1 μm diameter of were obtained. The possibility of using such optical elements to solve the problems of increasing the efficiency of IR radiation detection, signal amplification and conversion to visible and near-infrared ranges.

Latent tracks and track-etched membranes micro- and nanosized entities are promising research objects. The peculiarity of such structures is that they are discrete in nature. As the distance from the track axis increases, the physical and chemical characteristics of these entities change to their original values. The track size also depends on the mass and energy of energetic ions. For example, the maximum size of Kr ions with an energy of 1 to 2 MeV/amu is 50 nm according to preliminary data. Changes in the track area over the distance from the ion trajectory have been studied in this work.

Growth of KDP crystals from aqueous solutions with SiO2 particles whose size ranges from 10–2 to 400 μm in the static and dynamic modes has been studied. The effect of mother-solution supersaturation and particle size and concentration on the process of particle capture by a growing crystal is considered as well as types of inhomogeneities formed in the crystal under the influence of these factors. It is shown that the larger the particle size, the higher the probability of particle capture by a crystal. The influence of supersaturation, growth rate, face morphology, and particle concentration on particle capture and defect formation in crystals is also discussed.

The high-rate growth of nickel sulfate hexahydrate NiSO 4 · 6H 2 O (α-NSH) crystals up to 120 × 120 × 65 mm 3 in size is described for the first time. The data on the distribution of related impurities in the {011} and {001} growth sectors of α-NSH crystals grown at different rates are reported. The transmission spectra of both growth sectors of these crystals are obtained. The structural quality and the optical properties of rapidly and slowly grown α-NSH crystals are compared. It is established that the {011} growth sector of crystals grown at rates exceeding 5 mm/day shows the best characteristics for application in UV filters.

Using IR spectroscopy, we have established that bombardment of polypropylene with accelerated Xe+6 ions leads to radiation-induced and post-radiation oxidation with formation of carbonyl and hydroxyl groups and amorphization of its structure. Upon subsequent treatment of the bombarded polymer with sulfuric acid-dichromate cleaning solution, we see formation of not only a porous structure but also of a surface thin layer (approximately 0.01 mum) with amorphous structure. We present the results of a study of the structurally selective properties of nuclear-pore filters obtained on the basis of thin polypropylene films bombarded with accelerated heavy ions and etched with sulfuric acid-dichromate cleaning solution.
