Calculation of molarity. 38% HCl by mass means that 38 g of HCl are present in 100 g of the solution. "Volume of 100 g of the solution"=("Mass ")/("Density")=(100g)/(1.19"g cm"^(-3))=84.03cm^(3)=0.0840L Molar mass of HCl = 36.5"g mol"^(-1) therefor
First, all films were insoluble in concentrated HCl. Secondly, swelling rates of different amounts of diamine crosslinked copolymers were measured in ethylene carbonate/dimethyl carbonate and in methyl ethyl ketone; it was proved that the higher the molar percentage of diamine, the higher the cross...
Chitin/chitosan derivatives are promising candidates as biomaterials for wound healing, tissue engineering and drug delivery applications. Being fabricated from freely available natural resources, these biomaterials can be economically more feasible as compared to the synthetic polymer materials. Furthermore, ...
Here we present six new co-structures of potent ligands bound to CAMKK2 identified from a library of commercially-available kinase inhibitors. Enzyme assays confirmed that most of these compounds are equipotent inhibitors of both human CAMKKs and isothermal titration calorimetry (ITC) revealed that ...
