silicon/ local structureporous SiEXAFSX-ray absorptionK-edgeX-ray absorption measurements at the K-edge of silicon have been done in transmission mode on three powdered samples of porous silicon (p-Si) with 50%,
71 After battery tests, the porous Si anode delivered a high reversible capacity of 2,900 mAh g−1 at the current density of 400 mA g−1 and retained a stable capacity above 1,100 mAh g−1 after 600 cycling test at 2,000 mA g−1. Amorphous silicon inverse opals were ...
Companies operating in industries with relatively inelastic consumer demand, such as A&D, have more flexibility to follow this strategy, since their pricing power derives from limited competition on product offerings and the structure of their procurement contracts (for example, cost-plus or cos...

The interface of high-quality crystalline silicon/hydrogenated amorphous silicon (c-Si/a-Si:H) is indispensable for achieving the ideal conversion efficiency of Si heterojunction solar cells. Therefore, it is extremely desirable to characterize and control the interface at the atomic scale. Here, we...
近日,天鼎丰中东生产基地项目迎来关键节点:主车间、成品库及厂区工程已施工至地面层,整体建设进度达30%,标志着项目进入快速推进阶段。作为天鼎丰全球化战略的重要支点,天鼎丰沙特项目自2024年8月签约、2025年2月启动土建以来,始终以高效、精准的节奏落实建设计划,预计2025年12月全面投产,为中东及全球市场提供高性能非织...
The same report introduced the three pillars or principles of environmental, social and economic sustainability, also known as ESG (Environmental, Social, Governance). These criteria are the standards used for assessing the impact and sustainability of a company's activities. They have been divided ...
Nanoscale amorphous materials are very important member of the non-crystalline solids family and have emerged as a new category of advanced materials. However, morphological control of amorphous nanomaterials is very difficult because of the atomic isotropy of their internal structures. In this review,...
its controlling rights may be in the hands of a local actual controller. Once it encounters a debt crisis or family disputes, "selling shells" becomes a way out. Today, when such companies are ready to "join hands", the target is usually not PE funds, but industrial buyers with downstream...
silicon oil, and water create a dynamic environment wherein the forces at play lead to the re-establishment of previously formed shapes when agitated. This discovery not only tempts further exploration into thermodynamic boundaries but also opens new avenues for applications in ...
