Superior Cycling Stability of Moisture-Resistant Silica Aerogel Thermal Insulation Composites via Hydrothermal-Assisted Drying Process

Abstract Fiber-reinforced SiO2 aerogel thermal insulation composites are low density, high-temperature resistant, and exhibit low thermal conductivity, making them widely used in aerospace, petrochemical, and related fields. However, when subjected to an alternating high-temperat...

Atomic Defect-Mediated Charge Trapping Enables Multimodal Plasticity in van der Waals Heterostructures for In-Sensor Neuromorphic Vision

Abstract Neuromorphic hardware that unifies sensing, memory, and learning at the device level remains challenging due to limited optoelectronic comodulation and rigid architectures. Here, we report a flexible, van der Waals (vdW)-integrated MoS2/hexagonal boron nitride (h-BN)/gra...

Nanostructured Zirconia-Based Aerogels for High-Temperature Thermal Insulation

Abstract Zirconia-based aerogels are lightweight, porous materials made up of interconnected zirconia nanoparticles, forming continuous three-dimensional nanoporous networks. Their high melting point, low density, high porosity, and low thermal conductivity make them promising ca...
