Both primary and secondary structures of CEP were hardly changed, while disulfide bonds and hydrophobic forces between amino acid residues of CEP were interrupted by three treatments, releasing free sulfhydryls and hydrophobic groups. With the free moiety accumulation, the reformed interactions between ...
The framework was developed through Living by Chemistry (LBC), a chemistry curriculum project with, an assessment system for secondary and university chemistry objectives called ChemQuery, both funded by the National Science Foundation (NSF). ChemQuery is an assessment approach that uses this ...
Positron emission tomography (PET) constitutes a functional imaging technique that is harnessed to probe biological processes in vivo. PET imaging has been used to diagnose and monitor the progression of diseases, as well as to facilitate drug developmen
Precisely quantifying transition metal (TM) redox in bulk is a key to understand the fundamental of opti-mizing cathode materials in secondary batteries. At present, the commonly used methods to probe TM redox are hard X-ray absorption spectroscopy (hXAS) and soft X-ray absorption spectroscopy ...
They proposed to adopt the term “rotaxane effect” to identify the large thermodynamic stabilization (reflected in a very low acidity) of the secondary-ammonium moiety due to the strong interaction with the crown ether wheel. The first strategy involved an exchange with a competitive counter ion ...
Thus, we analyzed the mass and chemical composition variation of EDL within electrochemical operation by electrochemical quartz crystal microbalance, in-situ X-ray photoelectron spectroscopy, and time-of-flight secondary ion mass spectrometry. We found that N-doping triggers specifically adsorbed propylene...
Secondary reactions [1]. HPLC. The next reaction in the series. [1] Protections, oxidations, etc. Ex. Contaminant an amine? Treat with acetyl chloride and base. RF shoots up, and the column is no longer difficult. Transient protections are also useful for 1,3-diketones and other tautomeri...
2. Sensible heat flux is the heat energy is transferred from the Earth’s surface to the atmosphere by conduction and convection. 3. The term “soda lake” defines a class of saline lakes with water/brine chemistries having an excess in total alkalinity (≈[HCO3−]+2[CO3], i.e., th...
2. Chalcogen bonding interactions involving oxygen Usually, halogens and chalcogens act as the noncovalent bond acceptors in the secondary coordination sphere of metal complexes. The electrophilic behavior of the halogens or chalcogens as the halogen or chalcogen bond donor, respectively, has been wel...
M. Infinite Secondary Building Units and Forbidden Catenation in Metal–Organic Frameworks. Angew. Chem. Int. Ed. 2002, 41 (2), 284–287. Copyright John Wiley & Sons, 2002. Building on the approach set forth by Yaghi coworkers were also able to prevent interpenetration using Mn ...
