Efficient strategies for the introduction of arginine residues featuring acetylene or azide moieties in their side chains are described. The substituents are introduced in a way that maintains the basicity of the guanidine moiety. The methodology can be used e.g. for non-invasive labeling of arginine-containing peptides. Its applicability is demonstrated by the introduction of 'click' handles i...

The thermal stability of the molten slag plays an extremely important role in smooth production blast furnace. In this paper, effects basicity, Al2O3 content and MgO on during heat fluctuations were investigated. effect basicity composition viscosity behavior was measured by rotating cylinder method under condition fluctuation constant temperature. temperature solid phase precipitation calculat...

Gels prepared from metal containing ionic liquids with cross-linked poly(ethylene glycol) have surface compositions and mechanical properties that can be controlled by Lewis basicity acidity of the species.

In view of the deficiencies traditional methods to study dissolution kinetics solid oxides in molten slag, a novel method based on single hot thermocouple technique (SHTT) is proposed this paper. The feasibility verified and controlling means experiment reproducibility explored. And effect slag basicity Li2O content behavior Al2O3 mold flux investigated via SHTT. results show that: 1) Under con...
