Ni-Ru bimetallic porous carbon sphere(Ni-Ru@PCS) catalysts were synthesized via formaldehyde-assisted, metal-coordinated crosslinking sol-gel chemistry, in which biomass-derived tannic acid and F127 surfactant were used as carbon precursor and soft template, respectively, and Ni2+and Ru3+were used as cross-linkers. In the developed method, Ni-Ru particles became uniformly dispersed in the carbon skeleton due to strong coordination bonds between metal ions(Ni2+and Ru^(3+)) and tannic acid molecules and bimetal interactions. The as-synthesized Ni-Ru10:1@PCS catalyst with a loading Ni:Ru mole ratio of 10:1 was applied for the selective hydrogenation of glucose to sorbitol, and provided 99% glucose conversion with a sorbitol selectivity of 100% at 140℃ in 150 min reaction time and exhibited good stability and recyclability in which sorbitol yield remained at 98% after 4 cycles with little or no metal agglomeration. The catalyst was applied to glucose solutions as high as 20 wt% with 97% sorbitol yields being obtained at 140℃ in 20 h. The developed bimetallic porous carbon sphere catalysts take advantage of sustainably-derived materials in their structure and are applicable to related biomass conversion reactions.

Chemical warfare agents represent a severe threat to mankind and their efficient decontamination is a global necessity. However,traditional disposal strategies have limitations, including high energy consumption, use of aggressive reagents and generation of toxic byproducts. Here, inspired by the compartmentalized architecture and detoxification mechanism of bacterial microcompartments, we constructed oil-in-water Pickering emulsion droplets stabilized by hydrogen-bonded organic framework immobilized cascade enzymes for decontaminating mustard gas simulant(2-chloroethyl ethyl sulfide, CEES) under sweet conditions. Two exemplified droplet systems were developed with two-enzyme(glucose oxidase/chloroperoxidase) and threeenzyme(invertase/glucose oxidase/chloroperoxidase) cascades, both achieving over 6-fold enhancement in decontamination efficiency compared with free enzymes and >99% selectivity towards non-toxic sulfoxide. We found that the favored mass transfer of sugars and CEES from their respective phases to approach the cascade enzymes located at the droplet surface and the facilitated substrate channeling between proximally immobilized enzymes were key factors in augmenting the decontamination efficacy. More importantly, the robustness of immobilized enzymes enabled easy reproduction of both the droplet formation and detoxification performance over 10 cycles, following long-term storage and in far-field locations.

将出口产品质量测算的两种方法——需求信息反推法和供需信息推导法纳入同一模型框架内,使用2000-2013年微观样本数据对中国出口产品质量进行了全面测算、多维度分析。研究发现:不同方法测算的产品质量指标之间存在正向的相关性,但在使用需求信息反推法时对回归方程的处理应更加谨慎;考察期内中国出口产品质量实现了一定程度的提升,其中私营企业出口产品质量水平低于国有企业和外资企业,一般贸易出口产品质量水平低于加工贸易,低技术出口产品的质量水平低于高技术出口产品,但质量水平较低的类型均表现出更高的提升速度,从而使质量差距逐渐缩小甚至实现赶超;从企业出口行为看,企业出口深度与其产品质量表现出显著的正相关,而企业出口广度则无此特征。
