The fibred magnesium hydroxide from the bracite was treated with a surface active agent. The modified fibred magnesium hydroxide as flame-retardant, boric acid, barium stearate, polydimethyl siloxane fluid, vinyltriethoxysilane as synergists of the flame-retardant were added to polyene resin. The flame-resistance polyene material prepared meets the requirements of EWCZ-6287-1. (Author abstract) 2 Refs.

In the present work it is shown that the single phase lagging heat conduction not only avoids the infinite heat propagation speed assumed by the conventional Fourier law, but also complies with Galilean principle of relativity. Therefore it is more advantageous than the Cattaneo-Vernotte model. Based on the single-phase-lagging heat conduction model, the condition for the occurrence of thermal vibration of heat conduction is established. In order to resolve the contradiction that the thermal vibration violates the second law of thermodynamics, the extended irreversible thermodynamics is improved and a generalized entropy definition is introduced. In the framework of the newly-developed extended irreversible thermodynamics the thermal vibration phenomena are consistent with the second law of thermodynamics.

We report a large-scale surface with continuously varying wettability induced by ordered gradient *** gradient pattern is generated from nonuniform interference lithography by utilizing the Gaussian-shaped intensity distribution of two coherent laser *** also develop a facile fabrication method to directly transfer a photoresist pattern into an ultraviolet(UV)-cured high-strength replication molding material,which eliminates the need for high-cost reactive ion etching and e-beam evaporation during the mold fabrication *** facile mold is then used for the reproducible production of surfaces with gradient wettability using thermal-nanoimprint lithography(NIL).In addition,the wetting behavior of water droplets on the surface with the gradient nanostructures and therefore gradient wettability is investigated.A hybrid wetting model is proposed and theoretically captures the contact angle measurement results,shedding light on the wetting behavior of a liquid on structures patterned at the nanoscale.

NLRP3炎症小体是重要的细胞内多蛋白复合物,参与机体固有免疫,其异常激活将会引发一系列炎症性疾病及自身免疫性疾病.因此,NLRP3炎症小体活性的精确调控对于维持机体免疫稳态和健康至关重要.NLRP3的蛋白水平是炎症小体激活的限速步骤,必须严格调控以避免病理性损伤和相关疾病.在本研究中,本团队发现在抑制法尼基转移酶亚基(farnesyltransferaseα,FNTA)基因表达的THP-1分化巨噬细胞中,ATP诱导的NLRP3炎症小体激活水平显著性下调.FNTA以依赖其PRR序列的方式来抑制NLRP3发生K48连接的泛素化修饰,抑制NLRP3被货物受体NDP52识别及其介导的自噬降解,从而正向调控NLRP3炎症小体的激活.
