latex beads, dimethylacrylamide beads optionally cross-linked with N,N′-bis acryloyl ethylene diamine, glass particles coated with a hydrophobic polymer, or any other material having a rigid or semi-rigid surface; and 2) soluble supports such as low molecular weight non-cross-linked polystyrene. ...
In considering the cost of metathesis catalysts, there is a continuous need to develop more reactive catalysts with high TONs. Recovery of the catalyst after the reaction can play an important role in determining the economic viability of a process. The development of water-soluble metathesis cataly...
The discovery of NHS esters as efficient acylating agents substantially expands the variety of N7acylated compounds that can be prepared through this route. In general, the N7acylated compounds of Series 2 are sparingly soluble in common organic solvents or water. Therefore, most of the products...
synergism which occurs in the organic phase may be caused by one of the following factors: 1) the activity of the extractant is affected thermodynamically, or 2) the composition of the metal-bearing species forms
37 °C for 20 h under oscillation. Immediately afterwards, the samples were immersed in ice, to stop microbial activity, and centrifuged at 6800 × gfor 10 min. The supernatant, representing the soluble fraction potentially absorbed after fermentation, was collected and stored at −...
We analyzed the effect of Cornelian cherry varieties differing in fruit color (‘Yantaryi’—yellow fruits, ‘Koralovyi’—coral fruits, ‘Podolski’—red fruits) and the production method on the physicochemical and antioxidative properties of Cornelian cherry vinegars, and on their content of iridoi...
