dyes in solid-state photovoltaic devices known as organic solar cells (OSCs). The power-conversion efficiency of tandem OSCs already reportedly exceeds 17% by processing state-of-the-art polymer donors and non-fullerene acceptors from their mixed solution, but this efficiency is still far below thapaltry 发表于 2025-3-27 11:47:19
coordination of the International Halley Watch, has reached a new peak of activity. The brainpower brought to bear has led to a plethora of new and exciting results, and our understanding of comet phenomena has increased in an unprecedented manner. In this book we review the physics and chemistry ofNEEDY 发表于 2025-3-27 15:19:01
Heinrich Teudtonventional probes to study the complex structure of this novel form of matter. The decagonal quasicrystals in particular appears to have a far less complicated phase diagram and an extreme phase stability compared to their three dimensional icosahedral counterparts. We have grown several millimeterAmorous 发表于 2025-3-27 21:16:13
Heinrich Teudtexercised by means of a metal-semiconductor barrier. This device and a subsequently modified structure employing an aluminum oxide dielectric spacer. were unsuccessful because of an inability at that time to prepare an electrically suitable surface. Interestingly, both these devices were proposed useczema 发表于 2025-3-28 01:16:37

Unifying definitions of acid- and base-neutralizing capacity (alkalinity and acidity) are helpful in appreciating the major H. yielding and H. consuming processes occurring in the atmosphere, in the watersheds, and in the lake.

Heinrich Teudton photoemission spectroscopy that the detailed electronic structure of these systems has become accessible . Photoemission spectroscopy provides unique information on these solids, and significant progress has been made recently in understanding electronic states in quasi-low dimensional solids.极小 发表于 2025-3-28 07:26:46
Heinrich Teudts of the last decades. This trend may involve a lowering of the dimensionality of the systems studied, besides a mere reduction in size. As regards dimensionality, one may define a .-dimensional system as an object which has infinite extension only in a restricted number . of spatial directions, and思考 发表于 2025-3-28 11:28:25
