Formation of oxygen protective layer on monolayer MoS low energy electron irradiation.

Monolayer molybdenum disulfide (MoS) semiconductors are the new generation of two-dimensional materials that possess several advantages compared to graphene due to their tunable bandgap and high electron mobility. Several approaches have been used to modify their physical properties for optical device applications. Here, we report a facile and non-destructive surface modification method for monolayer MoS electron irradiation at a low, 5 kV accelerating voltage.

Hierarchical Activated Carbon-MnO Composite for Wide Potential Window Asymmetric Supercapacitor Devices in Organic Electrolyte.

The consumption of electrical energy grows alongside the development of global industry. Generating energy storage has become the primary focus of current research, examining supercapacitors with high power density. The primary raw material used in supercapacitor electrodes is activated carbon (AC).

Effect of hydrogen on magnetic properties in MgO studied by first-principles calculations and experiments.

We investigated the effects of both intrinsic defects and hydrogen atom impurities on the magnetic properties of MgO samples. MgO in its pure defect-free state is known to be a nonmagnetic semiconductor. We employed density-functional theory and the Heyd-Scuseria-Ernzerhof (HSE) density functional.

Photoenhanced Water Electrolysis in Separate O and H Cells Using Pseudocapacitive Electrodes.

Water electrolysis has received much attention in recent years as a means of sustainable H production. However, many challenges remain in obtaining high-purity H and making large-scale production cost-effective. This study provides a strategy for integrating a two-cell water electrolysis system with solar energy storage.
