Improve the Thermal Conductivity, Insulation Performance and Mechanical Properties of Silicone Rubber by Constructing EG‐PDA‐Cu Hybrid Nanoparticles

open access: yesJournal of Polymer Science, EarlyView.
In this work, a novel expanded graphite‐supported nano‐copper polydopamine composite was designed and synthesized. The procedure involved first modifying EG via a mussel‐inspired technique to deposit a polydopamine coating, after which Cu2+ ions were reduced to immobilize copper nanoparticles onto the EG‐PDA substrate.

Development of NMP‐001, A Nitromethane‐Based Green Propellant

open access: yesPropellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT This paper discusses the development of a model monopropellant that is aimed at exploring the applicability of nitromethane‐based propellants as an alternative to hydrazine. This approach addresses the challenges faced by HAN‐, ADN‐based propulsion by being more cost‐effective while providing similar performance figures.

From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

Indocyanine Green–Inspired Polymeric Chromophores With Intrinsic Photostability for Near‐Infrared Imaging

open access: yesSmall, EarlyView.
Indocyanine green (ICG) is widely used for near‐infrared imaging but suffers from poor photostability. Here, an indocyanine green–inspired polymeric NIR chromophore is introduced, exhibiting intrinsically enhanced photostability and biocompatibility.

Synergistic Pyroelectric‐Bolometric Coupling in Tellurene Nanowire for Energy‐Efficient Artificial Vision

open access: yesSmall, EarlyView.
Synergistic pyroelectric–bolometric coupling in Tellurene nanowires enables efficient photothermal conversion and self‐driven synaptic functionality. Edge‐induced polarization and temperature‐dependent resistance cooperatively generate enhanced transient responses and multilevel conductance states.

Molecular‐Level Engineered Approach Induces Built‐in Electric Field Modulation in G‐C3N4/CoMoS2 Heterojunction for Enhanced Hydrogen Generation via Urea Oxidation

open access: yesSmall, EarlyView.
Urea‐assisted electrolysis is demonstrated as an energy‐efficient route for hydrogen production by replacing the sluggish oxygen evolution reaction with kinetically favorable urea oxidation. An intrinsic electric‐field‐driven g‐C3N4/CoMoS2 heterojunction induces directional charge redistribution, promotes selective urea activation, and accelerates C─N ...

White light emitting molecular logic gates

open access: yesSmart Molecules, EarlyView.
White light emitting smart molecules with Boolean logic computing ability are surveyed. Abstract White light emitting (WLE) materials are of considerable interest with commercial and societal applications in video displays and lighting devices. A characteristic property of WLE materials is the luminescence profile spanning from 380 to 700 nm.

Advances in organic UV filters for sunscreens over the past decade

open access: yesPhotochemistry and Photobiology, EarlyView.
Highlighted organic UV filter frameworks that have been described for sunscreens over the past decade divided into three groups: derivatives of or inspired by approved organic UV filters, natural product‐based compounds, and miscellaneous. Abstract Ultraviolet (UV) radiation is a major environmental factor in photoaging, erythema, and skin cancer ...
