“…Until 1993, photo‐induced surface photografting polymerizations with both Norrish I and Norrish II initiators had been developed. Later, a large number of studies have been devoted to the surface modification of polymers and inorganic materials, as well as to the understanding of the interactions between the metal and polymer …”

This contribution presents a versatile strategy to transfer unactivated surface C–H bonds of polymeric substrates to C–R–F groups (R stands for a spacer and F stands for functional group) by UV light‐assisted surface free radical coupling. With p‐dimethylaminophenyl radical as a building block, various reactive groups, such as –CHO, –SH, –B(O)OH, –CN and –SO3−, are successfully grafted onto typical commercial polymer substrates including biaxially oriented polypropylene, polyethylene phthalate, ethylene tetrafluoroethylene copolymer and dimethyl silicone rubber. Fluorencence microscope images, X‐ray photoelectron spectroscopy, UV‐vis and fluorescence spectra support that the above functional groups are covalently bonded to the polymer substrates. The concentration of the reactive groups immobilized on the different substrates is in the order of 10−8 to 10−7 mmol mm−2 determined by UV‐vis spectrometry. In addition, as a proof‐of‐concept, the introduced functional groups are demonstrated by their special reactions, for example, –CHO reacting with –NH2 to synthesize Schiff base, –SH to detect silver ions, and the complexes of –C=N and Zn2+ to degrade Rhodamine B. The results indicate that one can fabricate an integrated molecular library on the surface of polymeric substrates at the molecular level by selecting the building blocks.

“…Разработки каждого элемента ЯОП представляют собой еще не решенные задачи. Варианты технологических решений по структурной организации на микро и нано мас штабе волоконно оптических трансляторов ЯОП с необходимой эксплуатационной проч ностью при экстремальных внешних воздействиях можно найти в работах [1,2]. В на шей работе рассматриваются подходы к выбору и получению радиаторов для гибрид ных ионизационных камер (ИК), в которых сочетаются электрические и оптические спо собы регистрации нейтронов, а также подходы к выбору конденсированных рабочих сред детекторов с необходимой чувствительностью и селективностью детектирования в сильных (потоки свыше 1⋅10 15 см -2 •с -1 ) нейтронных полях.…”

Ключевые слова: детекторы нейтронов, гамма детекторы, ядерно оптический преобразователь, ионизационная камера, сцинтиллятор, фторидное стекло, сильное нейтронное поле. ВВЕДЕНИЕНеобходимость совершенствования имеющихся и создания новых нейтронных детек торов связана с изменяющимися условиями работы радиационных устройств. Так, в активной зоне реактора уже достигаются температуры до 700°C, потоки нейтронов до irradiation with a neutron flux of 1⋅10 17 n/(cm 2 •s), the intensity of Nd IR luminescence in glasses based on zirconium fluoride (ZBLAN) increases in the presence of Gd, which interacts with neutrons.
