Substitution of oxygen atoms by sulfur at various locations in the nucleic acid framework has led to analogs such as the DNA phosphorothioates and 4'-thio RNA. The phosphorothioates are excellent mimics of DNA, exhibit increased resistance to nuclease degradation compared with the natural counterpart, and have been widely used as first-generation antisense nucleic acid analogs for applications ...

This paper considers the issues of improving strength characteristics foundations by injecting specially selected composite mortars into soils. The properties injection used in seismic hazardous areas are improved using various additives consisting wastes. article explores possibility a mortar modified with sulfur, which is waste from oil refining. influence its addition on materials studied. o...

The accumulation of marine biological growth has irreversible negative effects on shipping and coastal fisheries. In this paper, a new antibacterial nanofiller—triazole fluoroaromatic hydrocarbon?modified nano?zinc oxide (ZnO?APTES?TRF)—was prepared by Cu(I)?catalyzed azide–alkyne click chemical reaction. modification nano?ZnO with triazole ring hydrocarbons were testified FT?IR, XPS, EDS. graf...

When introducing self-healing properties to elastomers, it is often difficult balance their ability recover after damage with a good mechanical strength prior damage. We demonstrate that by replacing the activator system used in conventional accelerated vulcanization (CV) chemistry, from traditional zinc oxide (ZnO) and stearic acid complex formed between ω-propenyl functional oligomers of poly...
