The Markov chain Monte Carlo method as a statistical mechanics technique for the study of macroscopic systems has furnished the scientific community with great knowledge and advances in the theory of phase transitions. While a number of Monte Carlo models have been proposed for the study of surface growth, these model…

以炭黑(CB)粒子为导电填料,乙烯-乙酸乙烯共聚物(EVA)和低密度聚乙烯(LDPE)为基体树脂,在HAAKE转矩流变仪中制备了EVA/LDPE/CB导电复合材料,研究了CB粒子的分散形态、共混体系相形态以及其与EVA/LDPE/CB共混体系导电性能的关系.通过DSC、DMA、SEM、溶剂溶解等方法考察了EVA/LDPE两相体系随着EVA含量的变化引起的相转变情况,同时也考察了CB在EVA/LDPE共混体系中的选择性分散情况.
采用反应性增容的方法,通过熔融共混制备聚丙烯/乙烯-辛烯共聚物/纳米二氧化硅(PP/POE/nano-SiO2)三元复合材料.研究了加入反应性增容剂聚丙烯与甲基丙烯酸缩水甘油酯接枝物(PP-g-GMA)后复合材料的力学性能、结晶性能及加工性能.结果表明:PP-g-GMA与氨基化改性纳米二氧化硅(NH2-SiO2)发生开环反应,能够增强基体树脂PP与nano-SiO2的界面作用和相容性,使nano-SiO2均匀分散于PP中,有助于PP的异相成核.当PP/PP-g-GMA/POE/NH2-SiO2质量比为70/10/20/2时,冲击强度达到52.9 kJ/m2,弯曲强度达到53.24 MPa;与纯PP和PP/POE(80/20)相比,…
This thesis explores the use of plasmonic nanovoids for enhancing the efficiency of thin-film solar cells. Devices are fabricated inside plasmonically resonant nanostructures, demonstrating a new class of plasmonic photovoltaics. Novel cell geometries are developed for both organic and amorphous silicon solar cell mat…
Ingot casting technology has been expanded to large parts during the last decades. As the ingot sizes increase, higher quality of the as-cast semi-products is demanded, with regard to the control of casting defects like macrosegregation and structure inhomogeneity. In order to investigate macrosegregation and to estim…
Abstract The title compound is characterized by powder XRD and DFT calculations.
The copolymers of N-isopropylacrylamide and sodium vinylsulphonate were synthesised by free radical polymerisation. The layer-by-layer self-assembly of the copolymers with poly(allylamine) hydrochloride was performed through assembling onto silicon wafer to form multilayer films and onto CaCO₃ microparticles doped wit…
Abstract New three‐dimensional flower‐like NaY(WO4)2:Ln3+ (Ln: Eu, Yb/Er, Ym/Tm, Yb/Ho) microstructures with uniform shape are hydrothermally synthesized from aqueous solutions of Y(OH)CO3:Ln3+ (obtained from aqueous solutions of Y(NO3)3, Ln(NO3)3, and CO(NH3)2 at 85 °C for 3 h) and Na2WO4 (autoclave, 200 °C, 9 h), fo…
Excerpt In the microelectronics industry, silicon nitride is greatly employed as an encapsulant for silicon integrated circuits, as a diffusion barrier for water and sodium, as passivation and gate dielectric material and as local oxidation masks in integrated circuit processing. Accordingly, the number of thin film f…
