Our existing technology for using solar energy in space is based on photo-voltaic cells made of silicon. These are excellent for powering scientific instruments but far too expensive for ordinary human needs. Solar ponds may be cheap and efficient on earth but are not an appropriate technology fo...
observation station of the China observatory, the method is mature, stable and precise, can be widely applied to full solar disk telescope observation systems for various photospheres and chromospheres, and can be applied to an observation system comprising partial solar limb after being properly ...
Little is more basic than the first law of thermodynamics, synopsized as energy conservation. The first law governs how much a system’s internal energy changes during any process. The energy change equals the heat absorbed, plus the work absorbed, by the system. Every formulation of thermodynam...
In recent years, with the continuous exploitation of marine resources and the global development of marine engineering, deep sea-oriented crane systems have been widely used, and their control problems have also attracted great attention. Under the deep sea working environment, since the transportation...
Fully-aromatic, two-dimensional covalent organic frameworks (2D COFs) are hailed as candidates for electronic and optical devices, yet to-date few applications emerged that make genuine use of their rational, predictive design principles and permanent pore structure. Here, we present a 2D COF made...
Leaders take group photo at Belt and Road forum Chinese President Xi Jinping, foreign delegation heads and guests pose for a group photo at the Leaders' Roundtable Summit of the Belt and Road Forum (BRF) for International Cooperation at Yanqi Lake International Convention Center in Beijing, capit...

Another widely used AOP is the photo-Fenton system, which uses the incidence of UV/Visible radiation to induce the photoreduction of ferrous compounds from the catalyst, and also the photolysis of hydrogen peroxide (H2O2), with •OH as a product that can oxidize pollutants [16,17]. It is...
This paper proposes a systematic control for a solar photo-voltaic (SPV) array, diesel generator (DG) and battery energy storage (BES) integrated microgrid... J Philip,B Singh,S Mishra - Power India International Conference 被引量: 3发表: 2014年 Stand-alone PEM water electrolysis system for...
A real-time monitoring system of structural dynamic response based on TENG technology has been developed, as shown in Figure 1. Herein, we present the strain response as the primary monitoring parameter. To collect long-term real-time structural dynamic response, the strain sensor based on the ...
