摘要：近红外(NIR)光驱动水分解产生氢气(H_(2))一直以来都是光催化领域备受关注的问题,但由于其动力学和热力学方面的缺陷,迄今为止仍是一项艰巨的挑战.为了突破这一限制,我们通过简便的水热法设计出了富含硫空位的无贵金属二维(2D)ZnIn_(2)S_(4)-基光催化剂,并首次使用单组分ZnIn_(2)S_(4)-基材料实现了波长大于800 nm的近红外驱动制氢性能.根据价带光谱、紫外-可见-近红外DRS光谱、稳态PL光谱、瞬态光电流响应和EPR表征,我们揭示了存在一个高效的Urbach带尾吸收用于捕获近红外光.硫空位在ZnIn_(2)S_(4)纳米片中的成功构建不仅扩展了光谱吸收范围,而且具有出色的载流子扩散特性和丰富的活性位点.因此,我们的研究结果可能会为未来开发近红外响应的ZnIn_(2)S_(4)-基光催化剂用于实现高效近红外驱动制氢提供一定的指导.

摘要：Design-manufacturing chain (D-MC) is the most important link of the supply chain with the greatest possibility in cost reduction. How to strengthen the effective management of interfacial relationship between designer and manufacturer and increase the effcency of interface management concerns the effciency of the whole supply chain. In order to evaluate and improve the impacts of D-MC interfacial relationship, first we should construct the evaluation index system and then we should analyze the total cost and benefit of the interfacial relationship betterment, including the cost of member units in D-MC, the opportunity cost of cooperation partners, and the market returns resulted from the interfacial relationship improvement, which will advance the whole supply chain effciency as well as enhance the management performance of D-MC.

摘要：Toluene degradation performances were studied in a 10 L Two-Phase Partitioning Bioreactor(TPPB).The liquid phase consisted of a mixture of water and PDMS 50(Poly Di Methyl Siloxane,*** oil,viscosity of 46 m Pa·s) in the volume ratio of 75%/25%.Two series of experiments were carried out:in the first,the reactor was sequentially supplied with toluene whereas in the second,toluene was continuously *** sludge from the wastewater treatment plant of Beaurade(Rennes,France) was used at an initial concentration of 0.5 dry mass g·(mixture L)^(-1).The elimination capacity(EC) was investigated as well as the change in biomass concentration over *** biodegradation was very ef ficient(removal ef ficiency,RE=100%) for toluene flows ranging from 0.2 to 1.2 ml·h^(-1),corresponding to elimination capacities of up to 104 g·m^(-3)·h^(-1).For a toluene flow of 1.2 ml·h^(-1),the biomass concentration measured at the end of the experiment was 4.7 dry mass g·(mixture L)^(-1).The oxygen concentration in the liquid phase was clearly not a limiting factor in these operating *** on these results,an extrapolation leading to the design of a large-scale pilot TPPB can now be considered to study toluene degradation performances in industrial conditions.

摘要：In this paper, the classical problem of supply chain network design is reconsidered to emphasize the role of contracts in uncertain environments. The supply chain addressed consists of four layers: suppliers, manufacturers, warehouses, and customers acting within a single period. The single owner of the manufacturing plants signs a contract with each of the suppliers to satisfy demand from downstream. Available contracts consist of long-term and option contracts, and unmet demand is satisfied by purchasing from the spot market. In this supply chain, customer demand, supplier capacity, plants and warehouses, transportation costs, and spot prices are uncertain. Two models are proposed here: a risk-neutral two-stage stochastic model and a risk-averse model that considers risk measures. A solution strategy based on sample average approximation is then proposed to handle large scale problems. Extensive computational studies prove the important role of contracts in the design process, especially a portfolio of contracts. For instance, we show that long-term contract alone has similar impacts to having no contracts, and that option contract alone gives inferior results to a combination of option and long-term contracts. We also show that the proposed solution methodology is able to obtain good quality solutions for large scale problems.

摘要：A microwave-H202 process for sludge pretreatment exhibited high efticiencies of releasing organics, nitrogen, and phosphorus, but large quantifies of H202 residues were detected. A uniform design method was thus employed in this study to further optimize H202 dosage by investigating effects of pH and H202 dosage on the amount of 1-I202 residue and releases of organics, nitrogen, and phosphorus. A regression model was established with pH and H202 dosage as the independent variables, and H202 residue and releases of organics, nitrogen, and phosphorus as the dependent variables. In the optimized microwave-H202 process, the pH value of the sludge was firstly adjusted to 11.0, then the sludge was heated to 80~C and H202 was dosed at a H202 ：mixed liquor suspended solids （MLSS） ratio of 0.2, and the sludge was finally heated to 100~C by microwave irradiation. Compared to the microwave-H202 process without optimization, the H202 dosage and the utilization rate of H202 in the optimized microwave-H202 process were reduced by 80% and greatly improved by 3.87 times, respectively, when the H202：MLSS dosage ratio was decreased from 1.0 to 0.2, resulting in nearly the same release rate of soluble chemical oxygen demand in the microwave-H202 process without optimization at H202：MLSS ratio of 0.5.

摘要：本研究旨在设计、建造和测试一个中试规模的浮动模块化处理系统,并用以对美国佛罗里达州中部富营养化湖泊中的总磷(TP)进行去除。该处理系统由生物和物理-化学处理模块组成。用多种底物和水生大型植物组合构建了13种不同的中宇宙实验(mesocosm),分别测试了总磷(TP)和正磷(PO_4^(3-))的去除率及潜在的区域去除率。此外本研究对7种吸附介质进行了小型杯罐实验和柱实验,并对3种商业树脂进行了吸附能力的测试。完成这些独立的测试过程后,在佛罗里达中部的一个湖泊中,设计了一个浮岛处理系统(FITS)并运行了8个月。中宇宙实验对磷的平均去除率为40%～50%,平均去除量为5.0 g·m^(–2)·a^(–1)。其中沉水植物(SAV)系统和藻类洗涤器(AGS)效果最好,分别去除了20 mg·m^(–2)·d^(–1)和50 mg·m^(–2)·d^(–1)的磷,它们对磷的平均去除量分别为5.5 g·m^(–2)·a^(–1)和12.0 g·m^(–2)·a^(–1)。在吸附介质中,明矾渣(AR)的性能最佳,接触5 min后,PO_4^(3-)浓度降低了75%左右。在所测试的商品树脂中,PhosX树脂的去除效果最好,在30 min后去除了约40%的磷,60 min后去除了约60%的磷。在基线运行条件下展开实验,FITS对PO_4^(3-)的平均去除率为53%;使用PO_4^(3-)去除率的第50百分位和第90百分位以及FITS的环境足迹进行评价,结果表明系统的去除率分别为56%和86%;区域磷去除率在8.9～16.5 g·m^(–2)·a^(–1)之间。
