Among the different classes of impurities, we focus on charged impurities in an ultracold bath. When a single ion is brought in contact with an ultracold gas it is subjected to different reactive processes that can be understood from a cold chemistry approach. In this work, we present an ...
thelithologyof the substrates has more influence onsoil chemistry. Soils with a higher base status generally form in carbonate-rich loess orglacial driftand support nonacidic tundra vegetation. But with time, the vegetation succession gradually changes the soil chemistry by protonation or acidification ...

aIn this study surface chemistry of both treated and untreated samples were investigated using XPS analysis. 在被对待的和未经治疗的样品这研究表面化学使用XPS分析被调查了。[translate] a只用很少的时间就和同事们熟悉起来 Only uses the very few time on to be familiar with with the colleagues[translate...
These magmas can host much older crystals, stored at low and even sub-solidus temperatures, consistent with crystal chemistry data6,7,8,9. Changes in local bulk composition caused by reactive melt flow, rather than large increases in temperature, produce the rapid increase in melt fraction that...
After sacrifice, the serum of mice was collected and stored at −80 °C. The serum level of aspartate aminotransferase (AST) was measured with biochemistry slides for a chemistry analyzer (FUJI DRI-CHEM 4000i, Fujifilm Corporation). Fecal microbiota transplantation (FMT)...
[74] have used click-chemistry-type [2+2] cycloaddition reaction of TCNE and TCNQ with electron-rich alkynes to form the cyclobutene ring, which finally has given donor-acceptor chromophores in high yield. Kivala等。 (74) 使用点击化学类型 (2+2) TCNE和TCNQ的cycloaddition反应以富有电子的炔形成...

“Because of this, we’ve been able to do a couple of different studies where we can resolve neighboring masses of our reactant and product ions,” adds Krohn. This third arm of the ISM-chemistry experimental apparatus improved the resolution even further as the researchers now had multiple ...
