Copper nanoclusters modified molybdenum disulfide quantum dots probe for sensitive detection of tetracycline

open access: yesSensing and Bio-Sensing Research
By combining molybdenum disulfide quantum dots (MoS2 QDs) synthesized using a facile hydrothermal method with copper nanoclusters (Cu NCs), copper-ion-modified molybdenum disulfide probes (Cu-MoS2 QDs) were obtained, enabling sensitive detection and ...

The Investigation of Improvement Effects on Friction Properties of Mononuclear MoDTCs having Azaheterocycles by Episulfidation

open access: yesTribology Online, 2010
The effects of episulfidation on the frictional properties of mononuclear molybdenum dithiocarbamates having azaheterocycles were investigated. It was shown that the friction coefficients of the lubricants with the episulfided mononuclear molybdenum ...

Bridged h‐BN Nanosheets Coatings: Simultaneous Shielding Atomic‐Oxygen Irradiation and Achieving Superior Friction Performance

open access: yesAdvanced Science, EarlyView.
ABSTRACT To confront extreme space environments, a combination of inorganic and organic coatings can provide a pathway for offering highly durable radiation resistance and anti‐friction simultaneously. Herein, a strong interfacial 3D hydrogen‐bonding network is designed to create robust hexagonal boron nitride (h‐BN) based polymer coatings with ...

Systematic Phosphorus‐Driven Structural and Field Engineering of n‐a‐Si:H for Flexible n‐a‐Si:H/Te Near‐Infrared Photodetectors

open access: yesAdvanced Science, EarlyView.
Our research elucidates the systematic evolution of the microstructure and optoelectronic properties of n‐a‐Si:H governed by the phosphine dilution ratio. Optimally phosphorus‐doped n‐a‐Si:H is integrated with Te to form a flexible heterojunction, enabling high‐performance near‐infrared photodetectors.

Interface‐Directed High Fluorescence Efficiency Two‐Dimensional Molecular Crystals With Surface‐Exposed Active Sites

open access: yesAdvanced Science, EarlyView.
Here, we designed the Me‐FBSe molecule and prepared a two‐dimensional molecular crystal via liquid‐liquid interface assembly. The crystal preserves the high photoluminescence quantum while simultaneously ensuring the high‐density surface exposure of active sites.

Optimized Lipid Nanoparticles with Tail‐Modified Ionizable Lipids for Safer mRNA Delivery

open access: yesAdvanced Science, EarlyView.
Systematic engineering of hydrophobic tail architecture in vitamin B5‐derived ionizable lipids establishes a comprehensive structure–activity relationship framework for mRNA delivery. Combined lipidtail and formulation optimization identifies TM1‐OPT3‐C, a lipid nanoparticle platform that improves efficacy–safety balance through efficient mRNA delivery,

3D continuum phonon model for group-IV 2D materials

open access: yesBeilstein Journal of Nanotechnology, 2017
A general three-dimensional continuum model of phonons in two-dimensional materials is developed. Our first-principles derivation includes full consideration of the lattice anisotropy and flexural modes perpendicular to the layers and can thus be applied
