Electron Solvation in Neat Alcohols 6917
We have performed femtosecond studies of electron solvation in a series of neat linear alcohols. The measured formation time of the solvated electron is consistent with previous studies using solutes. The major character of electron solvation, i.e. the two-state character, is evidenced by the finding of an approximate isosbestic wavelength for methanol at 750 nm. Isotope effects for CH3OH, CH30...
متن کاملNeat Rings
A ring is called clean if every element is the sum of a unit and an idempotent. Throughout the last 30 years several characterizations of commutative clean rings have been given. We have compiled a thorough list, including some new equivalences, in hopes that in the future there will be a better understanding of this interesting class of rings. One of the fundamental properties of clean rings i...

کاتالیست یک سنتز جدید برای تیواترها توصیف شده است. واکنش الکل ها با آریل، هتروآریل و آلکیل تیو ل ها درحضور 1،3،5- تری آزو- 2،4،6- تری فسفرین-2،2،4،4،6،6 هگزاکلراید ((tapc به عنوان یک کاتالیست موُثر، بازده های خوب تا عالی از تیواترها را حاصل می کند. علاوه براین، واکنش تحت شرایط بدون فلز و بدون حلال پیش می رود، بنابراین یک مکمل جالب برای روش های شناخته شده سنتز تیواترها ارائه می دهد. یک مکانیسم ا...
15 صفحه اولSimAnt Simulation Using NEAT
In nature, ants in a colony often work together to complete a common task. We want to see if we can simulate this phenomenon. We create a simulation that looks at predator prey interactions based o↵ of the 1991 SimAnt game. In this game a spider attempts to eat individual ants from a colony, but if the ants form a large enough swarm they can work together to eat the spider. The question we are ...
متن کاملNeat Embeddings and Amalgamation
We present a property of neat reducts commuting with forming subalgebras as a definability condition. The purpose of this paper is to relate results on neat reducts, a notion particular to cylindric algebras to results on the “more universal” strong amalgamation property in a very general setting. It is known [7], [8] and [6] that amalgamation properties in a class of algebras correspond to int...
