The oxygen evolution reaction is a key reaction in water splitting. The common approach in the development of oxygen evolution catalysts is to search for catalytic materials with new and optimized chemical compositions and structures. Here we report an orthogonal approach to improve the activity of catalysts without alternating their compositions or structures. Specifically, liquid phase exfoli...

The dynamic characteristics of field electron emission from the layered structures with quantum wells have been qualitatively analysed. The main factor leading to appearance of the high frequency current oscillation is the negative differential resistance, observed under rather high electrical field. Layered structures with superthin barriers (like Si Si02 6(Si) Si02) seems to be likely to show...
