This course covers the brand new spec introduced in September 2015. Chemistry is concerned with the science of matter, particularly its structure, properties and reactions. Chemistry is of central importance to the sciences as a whole as the chemical reactions that it governs are fundamental to all...
7Li solid-state NMR spec-troscopy and Gaussian simulation reveal that the formation of local high Li+ ion concentration in the sep-arator and its low absorption energy with Li+ ion (62.2 kcal mol-1) is conducive to the ionic transportation. In particular, the assembled Li/separator/LiFePO4 ...
Herein, the coherent effects of local atomic and electronic structure in Li2RuxMn1 xO3 (LRMO) with a wide voltage window (1.3-4.8 V) is identified by in situ X-ray absorption fine spec-troscopy (XAFS) and chemometrics. We not only skillfully separated the redox active structures to ...
And it doesn’t matter if you’re taking GCSE AQA Combined Science (Trilogy) or GCSE Chemistry (Triple Science) - the app covers both of those specs at higher and foundation level. You just select the spec and level when you first start the app, and you can change these options at any...

Changes in the microbiota with the addition of MCOS and C-COS were measured at the genus level (Fig. 9). The relative abundance of Escherichia was significantly higher than that in the CON group in a concentration-dependent manner as the amount of MCOS increased. Lactobacillus belong to the ...
A pre-treatment process was proposed for the analysis of anode product composition using the atomic absorption spec- trometry method, and the anode states at working temperature (560 °C) were obtained by the Na-Ca-Zn ternary phase for the first time. The results indicate the discharge of ...
