Tunable Gain SnS/InSe Van der Waals Heterostructure Photodetector.

Due to the favorable properties of two-dimensional materials such as SnS with an energy gap in the visible light spectrum, and InSe, with high electron mobility, the combination of them can create a novel platform for electronic and optical devices. Herein, we study a tunable gain SnS/InSe Van der Waals heterostructure photodetector. SnS crystals were synthesized by chemical vapor transport method and characterized using X-ray diffraction and Raman spectroscopy.

Preparation and characterization of nano- and non-nanoscale Co₃O₄ spinels obtained from different methods and study of their performance in combustion of aromatics from polluted air-A comparison with Pt/γ-Al₂O₃ performance.

This article reports the development of oxidative precipitation (OP) method for synthesis of Co(3)O(4) as an environmental catalyst and comparison of its performance with that of obtained from conventional sol gel combustion (SG) method and industrial Pt/γ-Al(2)O(3) in remediation of toluene from air. Catalytic studies were carried out in a fixed bed reactor at 100-350°C under atmospheric pressure. Co(3)O(4) (OP) showed the highest activity in combustion of toluene.
