High‐Pressure Chemical Vapor Deposition Growth of Transition Metal Dichalcogenides With Minimized Sulfur Vacancies

National Materials, EarlyView.
High‐pressure chemical vapor deposition at 3800 torr elevates the sulfur chemical potential during MoS2 growth, suppressing sulfur‐vacancy formation. This thermodynamic control yields MoS2 with defect densities comparable to those of exfoliated crystals, enhanced crystallinity, uniform defect distribution, and improved electronic transport properties ...

Vibrational Exfoliation of 2D Materials

Small, EarlyView.
Vibrational energy folds, fractures and exfoliates atomically and molecularly thin materials. Combining experimentation and computational methods, this unique vibrational synthesis pathway is revealed. This process overcomes barriers of existing approaches by processing 1000 g/L dispersions without loss in yield.

Rounded Monodisperse Fluorescent Nanodiamonds

Small, EarlyView.
Nanodiamond (ND) shape control using rapid molten‐nitrate etching is studied as a scale‐up method for monodispersed rounded particles. Optimal etching condition (567°C for 6 min) yields NDs with atomically stepped surfaces and reduced sp2 content. Compared to angular control, rounded NDs exhibit an increased proportion of luminescent particles (66% vs.

Orthogonal numerical simulation on multi-factor design for rapid pressure swing adsorption

, 2017
A two-dimensional model is established to simulate the rapid pressure swing adsorption (RPSA) process used for air separation with single bed. The model considers the transport phenomena occurring in both axial and radial direction.

The Host‐Guest Assemblies of Metal–Organic Frameworks and Protic Ionic Liquids With ZIF‐8 and [Dema][TfO] – Structural Response and Ionic Conductivity

Small, EarlyView.
MOFs can serve as effective proton conductors owing to their porous structures and well‐defined channels. In this study, the protic ionic liquid [Dema][TfO] is introduced into ZIF‐8 cages. The confined [Dema][TfO] can transfer between adjacent ZIF‐8 cages, inducing cage expansion through the swing effect.

Interplanar Potential Difference‐Mediated Efficient Charge Separation in SrLi2Ti6O14 Towards Optimized Photocatalytic Hydrogen Evolution

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 6, November 2026.
The periodic quantum well formed by alternative stacking of SrO and LTO layers facilitates efficient photoinduced charge separation and thus significantly improves its photocatalytic hydrogen production performance. SrLi2Ti6O14 porous microspheres (SLTO PMSs) and SrLi2Ti6O14/TiO2 hollow sphere heterojunctions (SLTO/TiO2 HSs) are fabricated via ...
