Voltammetric behaviours of facilitated Li+ ion transfer by the solvents of lithium-based batteries are investigated, which is valuable for the dual-electrolyte Li-air batteries, but also for the ion detection, separation and extraction

Electrochemical Synthesis of Silver-Tetracyanoquinodimethane Nanorods at Agar Supported Water/1,2-Dichloroethane Interface

具有高导电性和独特电学性质的金属有机络合物AgTCNQ是一种重要的电荷转移盐.本文采用琼脂作为胶凝剂构成水|1,2-二氯乙烷液液界面；施加电压时银离子由水相穿过水凝胶进入有机相，与TCNQ-反应生成AgTCNQ纳米棒.结果表明液/液界面电化学方法为合成有机金属功能材料的有效途径.Silver-tetracyanoquinodimethane (AgTCNQ) is an important charge transfer salt due to its high conductivity and other electronic properties. In this communication, we report the synthesis of AgTCNQ at the liquid/liquid interface. Agar was used as a gelling agent to support water/1,2-dichloroethane (DCE) interface. Silver ions were transferred from the hydrogel into DCE phase, where they combined with TCNQ- to form AgTCNQ nanorods. The developed method can provide a new route for synthesis of functional materials based on the electrochemistry at the liquid/liquid interface.This work was supported by National Science Foundation of China (No. 20973142, No. 21061120456, and No. 21021002), National Basic Research Program of China (2011CB933700) and the National Science Foundation (CHE-1026582; MVM).This work was supported by National Science Foundation of China (No. 20973142, No. 21061120456, and No. 21021002), National Basic Research Program of China (2011CB933700) and the National Science Foundation (CHE-1026582; MVM).作者联系地址：1. 厦门大学化学化工学院化学系, 福建厦门361005; 2. 厦门大学固体表面物理化学国家重点实验室, 福建厦门361005; 3. 纽约市立大学皇后学院化学与生物化学系袁美国纽约11367Author's Address: 1.

Joint tank container demurrage policy and flow optimisation using a Progressive Hedging Algorithm with Expanded Time-Space Network

A key feature of the tank container (TC) operating industry is that customers overhold TCs to provide temporary storage equipment for their contents rather than provide their own storage facilities. TC operators charge a very profitable fee (demurrage charge) for this service making it an attractive business proposition, but it can be detrimental to holistic network flows and fleet sizing. This paper addresses the problem of jointly optimising TC demurrage policy and TC flow, in the face of uncertain TC maintenance times, to maximise profits. A progressive hedging algorithm with expanded time-space network (PHA-ETSN) is designed to tackle this tactical level optimisation problem as other established techniques struggle with this optimisation in terms of computational time and memory requirements. Experiments are performed to illustrate how the optimisation tool can be used to investigate how demurrage policy affects different operational costs and TC hire revenue and thereby profit. These experiments demonstrate how the optimisation tool can be used by managers not only to optimise demurrage policy but also to explore and to understand more deeply the costs and profits in their operations.</p
