Gas storage using fullerene based adsorbents

This invention is directed to the synthesis of high bulk density high gas absorption capacity adsorbents for gas storage applications. Specifically, this invention is concerned with novel gas absorbents with high gravimetric and volumetric gas adsorption capacities which are made from fullerene-based materials. By pressing fullerene powder into pellet form using a conventional press, then polymerizing it by subjecting the fullerene to high temperature and high inert gas pressure, the resulting fullerene-based materials have high bulk densities and high gas adsorption capacities. By pre-chemical modification or post-polymerization activation processes, the gas adsorption capacities of the fullerene-based adsorbents can be further enhanced. These materials are suitable for low pressure gas storage applications, such as oxygen storage for home oxygen therapy uses or on-board vehicle natural gas storage. They are also suitable for storing gases and vapors such as hydrogen, nitrogen, carbon dioxide, and water vapor

Rongsheng Group

Rongsheng Group was founded in 2005. Within two years of construction, its shipbuilding base in Rugao, Jiangsu, had been mostly set up and put into operation. Yet Shanghai Waigaoqiao Shipbuilding Co., Ltd., Hudong-Zhonghua Shipbuilding Group, and Jiangnan Shipyard Group had set up their production lines at Shanghai Changxing Shipbuilding Base, which would immediately change the competitive situation in the international shipbuilding industry. Meanwhile, the sub-prime loan crisis would slow down the development pace of the world economy, thus leading to asurplus of world shipping and shipbuilding capacity in the near future. The CEO of Rongsheng Group, Chen Qiang, was wondering the following questions: As the world economic situation and the competition patterns of the shipbuilding industry were changing, how could Rongsheng Group work out the detailed strategies and implementation plans based on the goals of the board of directors? Which industry should the Group be positioned in and find opportunities from for its further development (manufacturing, finance, energy or real estate)? How could it realize its targets in a shorter time

熔盛集团

熔盛集团成立于2005年，经过两年多的发展已经基本建成了在江苏如皋的造船基地，生产正在有条不紊地进行。然而，2008年初外高桥造船公司、沪东中华造船集团、江南造船集团三家中国最大的造船公司分别在长兴基地建立了自己的生产线，这将改变世界造船业的竞争格局。同时，受美国次级债影响，世界经济发展速度将减缓，世界航运能力和造船能力过剩的情况马上就会出现。面对世界经济的变化和造船行业竞争格局的变化，作为熔盛集团CEO的陈强面临着诸多战略问题：应该如何根据董事会的目标，分三个阶段提出具体的战略和实施计划？集团下一步的发展定位和机会应该在哪个领域？制造业、金融、能源，还是地产？如何才能加快实现这些目标

The Navigation System of a Logistics Inspection Robot Based on Multi-Sensor Fusion in a Complex Storage Environment

To reliably realize the functions of autonomous navigation and cruise of logistics robots in a complex logistics storage environment, this paper proposes a new robot navigation system based on vision and multiline lidar information fusion, which can not only ensure rich information and accurate map edges, but also meet the real-time and accurate positioning and navigation in complex logistics storage scenarios. Simulation and practical verification showed that the robot navigation system is feasible and robust, and overcomes the problems of low precision, poor robustness, weak portability, and difficult expansion of the mobile robot system in a complex environment. It provides a new idea for inspection in an actual logistics storage scenario and has a good prospective application

Platelike MFI Crystals with Controlled Crystal Faces Aspect Ratio

International audienceZeolite crystals offering a short diffusion pathway through the pore network are highly desired for a number of catalytic and molecule separation applications. Herein, we develop a simple synthetic strategy toward reducing the thickness along b-axis of MFI-type crystals, thus providing a short diffusion path along the straight channel. Our approach combines preliminary aging and a fluoride-assisted low-temperature crystallization. The synthesized MFI crystals are in the micron-size range along a-and c-axis, while the thickness along the b-axis is a few tens of nanometers. The synthesis parameters controlling the formation of plate-like zeolite are studied, and the factors controlling the zeolite growth identified. The synthesis strategy works equally well with all-silica MFI (silicalite-1) and its Al-and Ga-containing derivatives. The catalytic activity of plate-like ZSM-5 in the methanol-to-hydrocarbons (MTH) reaction is compared with a commercial nano-sized ZSM-5 sample, as the plate-like ZSM-5 exhibits a substantially extended lifetime. The synthesis of plate-like MFI crystals is successfully scaled up to a kilogram scale
