Making polyesters with conventional vinyl monomers is one of the most economical ways to develop sustainable polymeric materials. For polar vinyls, while their transformation into lactones has been studied extensively, there exists no further access synthesizing polyesters, presumably due nonstrained and nonpolymerizable nature obtained lactones. Herein, we report first facile synthesis that originated from critical classes vinyls-acrylates. Specifically, a series modular six-membered were...
Abstract Tendons exhibit outstanding mechanical performance due to their hierarchical and anisotropic structures. Despite notable progress in mimicking anisotropy, developing biomaterials that simultaneously high strength, excellent biocompatibility remains a significant challenge. In this study, novel strategy is proposed fabricate multiscale, tendon‐mimetic regenerated silk fibroin (RSF) scaffold with preferentially aligned microstructure superior properties. This integrates...
We investigated the acidity and concentrations of water-soluble ions in PM2.5 aerosol samples collected from an urban site Beijing a rural Gucheng, Hebei Province November 2016 to January 2017 gain insight into formation secondary inorganic species. The average SO42–, NO3–, NH4+ were 8.3, 12.5, 14.1 μg m–3, respectively, at 14.0, 14.2, 24.2 site. nitrogen sulfur oxidation ratios correlated with relative humidity (with correlation coefficient r = 0.79 0.67, respectively) loadings. Based on...
Transferring abundant, inexpensive, and nontoxic carbon dioxide (CO2) into biodegradable polymers is one of the ideal ways to promote sustainable development. Although a great deal preeminent researches has been reported in last decade, including well-designed organometallic complexes, Lewis pairs, etc. The moisture- air-sensitive nature these extensively used catalysts preclude their use industrial applications. Herein, we report novel stable catalyst system commercial zinc glutarate (ZnGA)...
A triple cropping system, combining spring maize, pearl millet, and twice-cut blast disease resistant Italian ryegrass, was examined for the 2016–2017 2017–2018 growing seasons to achieve quality herbage production in Miyazaki, southern Kyushu, Japan. The growth of three crops reached harvest, even though typhoon heavy rainfall occurred. Annual dry matter (DM) yield 4098 g m−2 4349 first second seasons, respectively. observed total digestible nutrients (TDN) were higher maize (up 68.2%...
The sustainable solution to the environmental problem of polymeric materials calls for efficient and well-controlled ring-opening polymerization catalytic systems. Inspired by highly reactive stereospecific bimetallic catalysts, three kinds Salen-Mn catalysts supported biaryl linking moieties are synthesized applied catalysis lactide (LA) ϵ-caprolactone (ϵ-CL) in this work. is initiated situ epoxide compounds, which ionic cocatalyst could accelerate reaction process. Mn-Mn coordination...
During the 5th China Arctic Research Expedition of R/V Xuelong (June–September, 2012) total gaseous mercury (TGM) in marine boundary layer along route was measured. The spatial distribution TGM determined from Shanghai to Bering Strait Northwestern-Pacific volcanic belt and around Iceland outside Ocean. ranged 0.17 9.03 ng/m3 with a mean 1.86 ± 1.21 (median: 1.55 ng/m3). Several peaks cruise exceeded 4.0 ng/m3. means leg1 leg4 (near Japan) were 1.99 0.71 2.56 1.39 ng/m3, respectively. In...
The concentrations of carbon monoxide and ozone in the marine boundary layer were measured during 6th Chinese National Arctic Research Expedition (from July to September, 2014). Carbon concentration ranged between 47.00 528.52 ppbv with an average 103.59 ± 40.37 ppbv. A slight decrease increasing latitude was observed, except for extremely high values over East China Sea which may be attributed anthropogenic emissions. Ozone 3.27 77.82 29.46±10.48 decreased sharply outside Ocean (during both...
The theory of Universal Grammar (UG) has aroused intense research interest in language acquisition. However, scholars hold different positions on the accessibility UG second acquisition (SLA). aim case study was to identify a L2 learner’s patterns preposition and article use determined interlanguage development. Two assumptions design were raised based indirect access position full UG. 7 eventually identified by error analysis. 6 categorized as grammatical overgeneralization while 3...
In this work, we designed a series of energetic materials with windmill-like structure based on guanidine and nitroazole, optimized them at the B3LYP/6-311G** level using density functional theory (DFT). According to optimization results, 6 molecules planar structures were screened out from 28 their regularities summarized. We calculated geometry, natural bond orbital (NBO) charge, frontier molecular orbital, surface electrostatic potential, thermochemical parameters. addition, properties...
