Advanced Science, EarlyView.Molecular confinement within van der Waals gaps of MoS2 is established as a powerful design strategy for selective and stable chemical sensing. Ethanol‐confined films simultaneously tune electronic doping, surface wettability, and sulfur vacancy configurations, suppressing water interference while enhancing NO2 adsorption.

Controlled growth of uniform silver clusters on HOPG
, 2005 We have investigated growth of silver clusters on three different, i.e. normally cleaved, thermally oxidized and Ar+ ion sputtered highly oriented pyrolytic graphite (HOPG), surfaces. Scanning tunneling microscopy (STM) observations reveal that uniformly

STM investigations of C6Br6 on HOPG and MoS2 [PDF]
Surface Science, 1994 Monolayers of the organic molecule hexabromobenzene on HOPG and MoS2 have been imaged with scanning tunneling microscopy. The flat lying molecules form an ordered close-packed array with unit cell parameters corresponding to their van der Waals radii. In both cases the overlayers are incommensurable to the substrate.

Ag Nanowire‐Integrated MoS2/ZnO Heterojunctions for Highly Efficient Photogenerated Charge Transfer
Advanced Electronic Materials, Volume 11, Issue 6, May 2025.A versatile strategy is reported for fabricating multi‐dimensional heterojunctions with significantly improved charge transfer capability. By integrating Ag nanowires with a MoS2/ZnO heterojunction, a fourfold increase in surface photovoltage is achieved, reaching 200 mV under visible light illumination.

Image contrast reversals in contact resonance atomic force microscopy
AIP Advances, 2015 Multiple image contrast inversions are observed along with the increase of modulation frequency for contact resonance atomic force microscopy (CR-AFM) imaging of a highly oriented pyrolytic graphite (HOPG) specimen.

Magneto-electrical orientation of lipid-coated graphitic micro-particles in solution† [PDF]
RSC Advances, 2016 We demonstrate, for the first time, confinement of the orientation of micron-sized graphitic flakes to a well-defined plane. We orient and rotationally trap lipid-coated highly ordered pyrolytic graphite (HOPG) micro-flakes in aqueous solution using a ...

Comparative Insights and Overlooked Factors of Interphase Chemistry in Alkali Metal‐Ion Batteries
Advanced Energy Materials, EarlyView.This review presents a comparative analysis of Li‐, Na‐, and K‐ion batteries, focusing on the critical role of electrode–electrolyte interphases. It especially highlights overlooked aspects such as SEI/CEI misconceptions, binder effects, and self‐discharge relevance, emphasizing the limitations of current understanding and offering strategies for ...
