In the current work, an analysis of effects Y on radiation hardening and microstructure response a V-4Cr-4Ti alloy has been conducted after 30 keV D ion irradiation at room temperature using transmission electron microscopy (TEM) nanoindentation. The results show that formation large Y2O3 small Y2V2O7 nanoparticles was confirmed, indicating addition reduces amount dissolved oxygen. shown to aff...

The 0.2C-2Si (mass%) steels with the addition of 0–4 mass% Cr were prepared by hot rolling followed subsequent annealing for normalization. subjected to friction stir welding (FSW) conducted above A3 temperature. For all steels, sound FSWed joints obtained. Microstructures and tensile properties using small specimens investigated both base materials zones. showed a relatively good balance stren...

BACKGROUND Small polyfunctionalized heterocyclic compounds play important roles in the drug discovery process and in the isolation and structural identification of biological macromolecules. It is expected that ready access to diverse sets of heterocycles can not only help improving the known biological and pharmacokinetic properties of drugs, but also assist the discovery of molecules that exh...

With the critical increase in patients suffering from various types of malignant growth, it is obvious that quick steps development novel and viable agents should be taken. In current study, we focused on a synthetic approach for synthesis tetrazole derivatives using Ugi-4CR by employing gold catalyst water: methanol media. Gold’s adjustable nature, unique characteristics, mild reaction conditi...
