Recent studies have revealed that single-layer transition-metal oxides and dichalcogenides
(MX2) might offer properties superior to those of graphene. So far, only very few MX2 …

The study of efficient, robust, and earth-abundant electrocatalysts for the hydrogen evolution
reaction (HER) is essential for hydrogen-based energy technologies. Previous works have …

In recent years, research effort has been dedicated towards the exploration of MXenes' solid
lubrication performance verifying an outstanding wear performance due to the formation of …

Pyrite FeS2 chemically combines lithium polysulphide (Li2Sn) to form active Li2FeS2+ n
complexes that substantially reduce the out-diffusion of dissolved Li2Sn from sulphur …

Transition metal nitrides are of great technological and fundamental importance because of

Laser micro-Raman spectroscopy has been used to study 20 of the most commonly
occurring sulphides (ie iron sulphides, copper sulphides and some sulphosalts) which cover …

Nearly every nonmetallic crystalline and glassy material has a potential use in optics. If a
nonmetal is suf ficiently dense and homogeneous, it will have good optical properties …
