Low Temperature Site‐Specific Pulsed Laser Annealing of MoS2

open access: yesSmall, EarlyView.
The application of laser pulses, of extremely short duration, is investigated as a potential new method to modify the atomic structure of ultrathin 2D materials for use in the creation of future electrical devices. The process is efficient, offering a site‐specific functionality, where regions of an electronic device that only requires annealing is ...

Efficient Photocatalytic Hydrogen Evolution Enabled by Defect‐ and Interface‐Induced Dual Built‐in Electric Fields in a ZnIn2S4/1T‐2H WS2 Heterojunction

open access: yesSmall, EarlyView.
An N, Sv‐ZnIn2S4/1T‐2H WS2 composite photocatalyst is constructed via an in situ hydrothermal‐solvothermal strategy, simultaneously forming a defect‐induced p‐n homojunction in ZnIn2S4 and a type‐II heterojunction with hybrid 1T/2H WS2. The coupled dual built‐in electric fields promote charge separation and direct photoexcited electrons toward sulfur ...

Disc‐Toroid Hybrid Lipid Nanoparticles for Efficient Drug Encapsulation and Subcutaneous Delivery

open access: yesSmall, EarlyView.
This study demonstrates sub‐50 nm solid‐lipid nanoparticles with long‐term stability, high drug loading, and strong tissue compatibility. Disc‐toroid morphology is confirmed and may play a role in cellular interactions, while low cytotoxicity and minimal systemic permeation confirm depot‐like behavior. These nanoparticles represent a versatile platform

Essential Role of Icosahedral Symmetry in the 3D Shape of AuAg Plasmonic Nanostars With High Aspect‐Ratio Legs

open access: yesSmall, EarlyView.
Electron nanodiffraction mapping was used to determine that the 3D leg configuration of branched plasmonic AuAg nanostars is associated with the icosahedral symmetry of the star core, providing a deeper understanding of their growth mechanism and thus paving the way to the development of optimized synthesis protocols targeting optical enhancement ...

Suppress Ru Over‐Oxidation Through Oxygen Vacancy Engineering – Showcase With Ni‐Modified RuO2 via Molten‐Salt Synthesis

open access: yesSmall, EarlyView.
Competitive OER catalyst for H2O splitting without using Ir is a luxury wish; Ru is an active element to do the job but often does not hold long. See how those scientists managed the task with Ni modified RuO2 suppressing Ru over‐oxidation through Oxygen Vacancy Engineering.
