Geometrical theory of diffraction for sound and vibration
, 2020 International audienceWe present a geometrical theory of diffraction (GTD) for sound radiation and structural response. Six types of hybrid rays are identified travelling either from structure-to-fluid (sound radiation) or from fluid-to- structure ...

Advanced 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 ...

The crystallographic structure of dental enamel and related apatites
, 1964 PhDSynthetic, biological and mineralogical carbonate-containing apatites have been studied, principally by infra-red absorption spectroscopy (using polarised or unpolarised radiation), The substitution of a carbonate ion for two hydroxyl ions in the ...

Advanced Science, EarlyView.Supramolecular hydrogels enable real‐time visualization of mechanical stress through supramolecular switching mechanotransduction. Adamantane‐modified cellulose functions as a responsive domain that undergoes an on–off transition between hydrated and dehydrated states via reversible β‐cyclodextrin–adamantane complexation and decomplexation.

Advanced Science, EarlyView.Cu‐MXene interfacial catalysts provide a promising platform for electrochemical NOx upcycling to ammonia. The synergy between Cu active sites and conductive, surface‐tunable MXene supports promotes NOx adsorption, intermediate stabilization, and selective NH3 formation while suppressing competing hydrogen evolution, offering a route toward sustainable ...

Advanced Science, EarlyView.A DLN dataset was built to analyze MABS composition versus in vitro/in vivo osteogenesis and angiogenesis. An MLP neural network, taking BG morphological parameters as input, extracts bioactive features from these datasets. A rabbit tibial defect model then validates 4D‐printed MABS for adaptability and bone regeneration in critical defects.

Influence of Top Electrode Metal on Resistive Switching in Multilayer MOCVD MoS2 Memristors
Advanced Electronic Materials, EarlyView.MoS2 memristors typically use evaporated noble metal electrodes. This study compares Pd, Ni, and Al electrodes and sputtered versus evaporated deposition. Pd is passive, while Ni damages MoS2, yielding poor switching. Sputtered Al enables reproducible ECM‐type switching with 95% yield, whereas evaporated Al forms an interfacial oxide that suppresses ...
