Robert X. Gao,Ruqiang Yanotic liquid crystals. The nonlinear optical effects as well as photoconductivity and the possibility of the formation of Langmuir-Blodgett-films of phthalocyanines and derivatives is discussed at some length. Several practical applications of these unconventional materials are mentioned.faction 发表于 2025-3-29 00:42:47

What is more challenging is the recognition of the boundaries beyond which speculation is idle, but within which useful new insights regarding the relationship of certain ores to their lithologic and tectonic environments may emerge.978-3-642-96785-6Series ISSN 0343-2181高射炮 发表于 2025-3-29 12:51:35

Robert X. Gao,Ruqiang Yannderlying unity is gradually developing in the field. For example, structural changes occurring in Fe S cores as electrons are 4 4 pumped in and out, in some measure resemble those observed in boranes and carboranes. The cleavage of alkynes via incorporation into carborane cages and subsequent cage
