When the copper (II) oxide disappears the solution is clear blue. method - 4 Stop adding the copper (II) oxide when some of it remains after stirring. Allow apparatus to cool completely. method - 5 Set up the filter funnel and paper over the conical flask. Use the clamp stand to hold...
Chemistry and Practical Application of Dipyrromethene Ligands, Salts, and Coordination Compounds as Optical Sensors for Analytes of Various Nature (A Review)open-chain tetrapyrroleszinc(II) and boron(III) chelatesluminophoresfluorescent detection
Late-stage specific and selective modifications of peptides and proteins at target residues under ambient conditions are the most facile routes to various bioconjugates. Here, the authors report an orthogonal modification of cysteine residues using alkyl thianthreium salts, which proceeds with excellent ...

One issue was then chosen randomly from each of the volumes, therefore making 320 issues in total. All were from the years 2003-2009. One final constraint was that all articles needed to follow the IMRAD structure. This formed their CRAC corpus, which comprised 1185 texts and a total of 4...

This is made possible by a novel photocleavable support that provides a free ribose 3’-amino group instead of the established supports that already contain the C-terminal amino acid, making synthetic access to this class of RNA-peptide conjugates more efficient than previous routes. Abstract ...
CO2 likes molten salts: Capture and in-situ electro-splitting of CO2 in molten salts integrates carbon reduction with preparation of advanced carbon/oxygen and desulfurization/denitration In this manuscript, Prof. Xiao and coworkers introduced the basic concepts, possible reactions and morphological varia...
SERS-based chemical taxonomy is attractive for practical SERS applications where the identity and concentration of analytes are unknown. Here, the authors demonstrate a machine learning framework for classifying “unknown” molecules that lie outside the boundaries of the models used. ...
4. Washing away the dissolved silver salts and drying the negative. 5. Printing, that is, shining diffuse light through the negative onto a sheet of sensitive photographic paper (a gelatin emulsion on paper). 6. Darkroom development of the exposed paper using developer solution much like that ...
