EBR胶乳凝胶的控制及其对ABS树脂冲击性能的影响

主要讨论了摩尔质量调节剂，延长后期反应时间，提高后期反应温度，过硫酸钾用量等对乙烯－丁二烯橡胶（EBR）胶乳凝胶的影响；同时讨论了低凝胶条件和高凝胶条件下凝胶对ABS树脂性能的影响。结果表明：低凝胶条件,ABS树脂的冲击性能随凝胶质量分数的增加而增加；高凝胶条件下，则随凝胶质量分的增加而降低，得到了EBR胶乳生产中凝胶的主要控制方法，并通过控制EBR胶乳凝胶来实现对ABS树脂冲击性能的控制。     

Position Unmanned Aerial Vehicles in the Mobile Ad Hoc Network

This paper considers the problem of employing multiple unmanned aerial vehicles (UAVs) to the mobile ad hoc network (MANET) as relay backbone nodes to construct the backbone network, to improve the network connectivity, and to address many issues in the MANET such as linkage, capacity, load balance, and reliability. With considering the dynamic nature of the problem, this study provides several linear location problem models and their extensions to accommodate these issues. Due to the size of linear location models associated with a large number of constraints, the problem becomes computational challenging even with modest size of nodes. To overcome the computational barrier, we recast these location problem models using a quadratic unconstrained binary optimization (QUBO) framework and solve these QUBO models with a Tabu search heuristic with preprocessing. The analysis of the solutions that are produced by QUBO together with the comparisons made with the linear model highlight both the attractiveness and robustness of the proposed approach. The results of this study provide support to future advanced routing protocol development.     

Preparation,characterization, and adsorption properties for metal ions of a novel chelating resin containing sulfoxide and diethylene glycol

A novel chelating resin containing sulfoxide and diethylene glycol, poly{4‐vinylbenzyl‐[2‐2‐(hydroxyethyl)ethoxyl]sulfoxide} (PVESO) was synthesized using chloromethylated polystyrene (PS‐Cl) as material. Its structure was characterized by elemental analysis, infrared spectra, and scanning electron microscopy (SEM). The adsorption capacities of the resin for Hg²⁺, Ag⁺, Cu²⁺, Zn²⁺, and Pb²⁺ at various pH values were determined. The maximum adsorption capacities for Hg²⁺ and Ag⁺ were 1.56 and 0.75 mmol g^?1 respectively. The resin had high selectivity for Hg²⁺ and Ag⁺ over the pH range 1.0–7.0. The adsorption capacities for Hg²⁺ and Ag⁺ under competitive condition were also determined by batch experiment method. In addition, the adsorption kinetics of the resin towards Hg²⁺ at different temperatures was also investigated. The results showed that the adsorption rate was governed by film diffusion at 20°C and 25°C, by particle diffusion at 30°C and 35°C. © 2006 Wiley Periodicals, Inc.

Fabrication of suspended carbon microstructures by e-beam writer and pyrolysis

A fabrication process has been developed to create suspended carbon microelectromechanical system (C-MEMS) structures. SU-8, a negative photoresist, was used as the starting material and was converted to the desired carbon microstructures using pyrolysis in an inert atmosphere. Suspended carbon-micro and nano electromechanical system (C-MEMS/NEMS) structures with feature sizes down to 500 nm were fabricated by ultra violet/electron beam (EB) lithography and pyrolysis. The problem of charging of the non-conductive SU-8 surface was solved by partially masking a thin metal layer to prevent the repulsion of negative charged electrons before EB writing. Complex suspended C-MEMS structures, such as bridges and networks have been formed. This fabrication method can accurately and reproducibly produce various suspended C-MEMS structures which have applications in microelectronics and biosensing.
