Aluminum phthalocyanines (AlClPc) adsorbed on the surface of silica nanoparticles with diameter of 60 nm in aqueous solutions have been found to form H-aggregates, which possess characteristic absorption spectra with bands (having maximum at 640 nm) in a shorter wavelength region with respect to the main Q-band of the…
С целью разработки новых нефототоксичных и чувствительных способов обнаружения новообразований проведен синтез и исследованы основные спектрально-люминесцентные свойства наночастиц, содержащих иттербиевый комплекс диметилового эфира протопорфирина IX (Yb-ПП) в полимерной матрице на основе лексана (ЛПМ). Наночастицы об…
Установлено, что максимальный уровень характеристик прочности достигается при проведении полной термообработки (закалка+искусственное старение) после сварки. Термическая обработка сварных соединений, выполненных сваркой трением с перемешиванием, приводит к выравниванию структурной неоднородности и устранению разупрочн…

this paper is about rheological properties of plasticized polymer solutions with different concentration of plasticizer. it was established that the investigated polymer solutions were threedimensionally structured systems which were shear thickened at low shear rates and maintained the thixotropic structural state un…
One solution to increase the life of pavement is to use material with high modulus in its asphalt base layer. The effectiveness of this layer as a part of pavement structure is closely dependent on how well its material is designed. This study presents the results of a series of tests on asphalt mixtures using polyole…
The development of low-Mo austenitic stainless steels for high-pressure hydrogen valves and joints was undertaken to contribute to resource saving. Low-strain-rate tensile tests were carried out at 233 K in 70 MPa high-pressure gaseous hydrogen. The fracture surfaces of specimens tested in high-pressure gaseous hydrog…
In this research, the study effect of irradiation on structural and optical properties of thin film (CdO) by spray pyrolysis method, which deposited on glasses substrates at a thickness of (350±20)nm , The flow rate of solution was 5 ml/min and the substrate temperature was held constant at 400˚C.The investigation of…
Compendium of Hydrogen Energy: Hydrogen Energy Conversion, Volume Three is the third part of a four volume series and focuses on the methods of converting stored hydrogen into useful energy. The other three volumes focus on hydrogen production and purification; hydrogen storage and transmission; and hydrogen use, safe…
利用Materials Studio软件中Growth Morphology方法模拟计算了1,1-二氨基-2,2-二硝基乙烯(FOX-7)的晶体形态和结晶习性,得到特定晶面的面心距离、面积、附着能等参数,确定了其形态学上重要的生长晶面及其表面结构.建立了双层结构模型,采用分子动力学模拟计算了溶剂分子和FOX-7主要生长面之间的相互作用,研究了溶剂效应对FOX-7溶液结晶过程中晶体形貌的影响,为FOX-7溶液结晶过程中溶剂的选择提供理论依据.采用实验的方法,在N,N-二甲基酰胺/丙酮结晶体系条件下重结晶制备了FOX-7,其外形规则、棱角圆润、长径比变小,与模拟结果具有一致性.
The addition of Au3. to spherical amine-capped CdSe@ZnS nanoparticles in toluene at room temperature and under darkness can lead to ternary CdSe@ZnS/Au nanohybrids. We demonstrate that this happens only when the nanoparticles possess a relatively thin ZnS shell, thus showing that thickness plays a key role in gold dep…
Corrosion phenomena such as galvanic corrosion, pitting, stress corrosion cracking and corrosion fatigue as well as the relevant anti-corrosion measures for magnesium alloys were summarized and analyzed. The micro- arc oxidation(MAO) technology for Mg- alloys was introduced in the aspects of process technique, film st…
