Study on the Transformation and Upgrading of Business Mode of Canadian Solar Inc. [PDF]
, 2015 太阳能作为一种可再生能源，与风电、水电、生物质能等可再生能源相比，具有取之不尽、用之不竭、清洁无污染、无需运输、能量转换环节少等独特优势。在国家相关政策的引导下，全国范围内出现了光伏产业的投资热潮，光伏产品规模迅速扩张，出现了重复建设和产能过剩的风险。与此同时，在欧债危机、美国经济低迷、贸易壁垒逐步加大的整体环境下，对外依存度达90%以上的中国光伏企业不得不面对量价齐跌的局面，原有的单纯部件或主机供应商的商业模式已无法推进企业的可持续发展。 在这样的大背景下，本文以阿特斯公司的商业模式转型升级为研究内容，

Preliminary Research of Abnormal Phenomena of Condensed Phase with Hydrogen(Deuterium) in Gas-Solid Phase [PDF]
, 2015 过去的一个世纪里，化石燃料支撑着工业和经济的发展，但化石燃料的有限储量和能源利用率低的现状导致我们不得不进行新能源的开发。1989年Fleischmann和Pons发现了简单条件下钯阴极电解重水的体系中产生300℃高温，超出了化学变化能够带来的能量，这种过量的热生成被称为异常过热现象。这种常规条件下大量产生能量的现象被称为人工可控的冷核聚变，为新能源的开发带来了希望。二十多年来，冷核聚变吸引了许多研究者投身其中，但由于实验条件复杂，结果重复性很低，该过热现象的真实性和可靠性至今仍没有得到可靠的证实 ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Platinum (Pt)‐based catalysts are crucial for the commercialization of hydrogen/metal air batteries, but they suffer from Pt scarcity, high cost, and nanoparticle dissolution/agglomeration, mainly leading to performance degradation. We address this by synthesizing a PtFe alloy catalyst (PtFe–PA–NC) via a phytic acid (PA) assisted pyrolysis ...

Subsidies, Net Zero Transition and Public Debt: An Analysis for the Oil and Gas Industry in Brazil
Latin American Policy, Volume 17, Issue 1, March 2026.Abstract Despite awareness of the challenges in promoting the decarbonization of the economy, explicit fossil fuel subsidies have increased considerably worldwide in the past decade, reaching an all‐time high at US$1 trillion in 2022. Considering the net‐zero transition and the increase of modern public debt, this article assesses the most relevant ...

Over-expression of Xylose isomerase/Xylulokinase and Construction of O2-tolerant hydrogenase in Klebsiella oxytoca HP1 [PDF]
, 2015 在石化燃料枯竭和全球气候变暖的双重危机下，氢气作为一种可再生、零排放和高热值的清洁能源载体而备受关注。关于氢能的研究主要围绕氢的制取和氢的利用两个方面展开。在众多制氢方式中，生物制氢因其生产成本低、原料来源丰富和环境污染小，从而成为制氢研究的热点。在氢的利用中，燃料电池技术一直以来都是研究的重点。氢酶是一种含金属的氧化还原酶，其广泛存在于微生物中，能够可逆地催化H+的还原和H2的氧化(2H++2e-↔H2)。无论是在氢的制取还是氢的利用中，氢酶都是氢能技术的核心之一 ...

Review of Policy Research, Volume 43, Issue 2, March 2026.ABSTRACT This study examines the paradoxical relationship between policy learning and capacity: governments need certain capacities to learn effectively, yet these same capacities often emerge from previous learning experiences. Through a comparative analysis of Hong Kong and Singapore's responses to SARS and COVID‐19, we demonstrate how policy ...
