A microwave assisted synthesis of three new series of of 1, 2, 4-triazolo [1, 5-a] pyrimidines (PK-101 to PK-110) has been synthesized by the mixture of 5-(methylthio)-2H-1,2,4-triazol-3- amine (0.01 mol), 4,4,4-trifluoro-1-(4-methoxyphenyl)butane-1,3- dione (0.01 mol) and an appropriate aromatic aldehyde (0.01 mol) in ethanol (5 mL) was irradiated under microwave conditions at 120 °C for 10-15 min. The structures of all the newly synthesized compounds are elucidated by FT-IR, mass spectra, 1H NMR and elemental analysis. The newly synthesized compounds are subjected to various biological activities viz., antimicrobial, antimycobacterial, anticancer and antiviral.

Structural and optical properties of nanocrystalline SnSe thin film confer in this paper. For that purpose Nanocrystalline thin film of SnSe was deposited at room temperature having thickness 1μm, 2μm, 3μm and 4μm. Structural and optical properties studied by XRD, TEM, AFM, and Uv-Vis- Nir spectroscopy methods of all thin films. From these studied we found there is a strong effect of thickness on structural and optical properties of Nanocrystalline SnSe thin film.
