Organic chemistry就要稍微复杂一些了,因为含碳链的可变性太多了,但是好在A-level是考虑到为几乎没有或者基础薄弱的同学们设计的,因此这部分内容也是从最基本开始。Introduction to organic chemistry,基础的Hydrocarbons.以及往有机结构碳链中加入最基本的其他Functional group。比如Halogen,hydroxy,carbonyl, carboxylic acid...
Spectrochimica Acta, Part A: Molecular and Biomolecular Spectroscopy (SAA) is an interdisciplinary journal which spans from basic to applied aspects of optical spectroscopy in materials, mathematic, chemistry, medicine and biology. The journal publishes original scientific papers that feature high-quality...

4 Landau level spectroscopy of α-As. a, dI/dV line map (top) and its derivative (bottom) under B = 8 T applied perpendicularly to the cleaved surface. The intense modulation in differential conductance is due to Landau quantization. b, Averaged dI/dV spectra at B = 0 T...
Fourier Transform Infrared Spectroscopy (FTIR) results show that chain breakage in the major backbone, synthesis of new groups, and oxidation of antioxidants have all altered the chemical composition of LDPE. The carbonyl groups formed as a byproduct of LDPE breakdown are responsible for the ...
Inductively coupled plasma mass spectroscopy showed that almost no cations were present in the pure H2O anolyte (Supplementary Fig. 41), except for Na+ at part per billion level, originating from the water source. Then, we tested the anodic product compositions. As expected, only O2 from the ...
