Rational Design of Broad‐Spectrum Anti‐Enteroviral Molecular Glues Targeting Enteroviral RNAi Suppressors

Advanced Science, EarlyView.
By leveraging this homodimerization mechanism, molecular glues were rationally designed to induce dysfunctional 3A dimerization, thereby restoring antiviral RNAi. The optimal molecular glue, VTP‐32, demonstrated potent and pan‐enterovirus (groups A, B, D) antiviral effects.

Boil-off gas management for onboard LH₂ in hydrogen-powered vehicles

Journal of Physics: Conference Series
Abstract Liquid hydrogen storage has the potential to address both the driving range limitations and high-pressure safety concerns associated with compressed hydrogen storage. However, the boil-off issue poses a significant challenge, limiting the adoption of liquid hydrogen storage for onboard applications in hydrogen-powered vehicles ...

Studio di un sistema di recupero del gas di boil-off da serbatoi LNG per veicoli stradali

, 2021
L’evaporazione del gas (Boil-Off) all’interno dei serbatoi criogenici è un fenomeno del tutto normale, ed avviene a causa del calore trasmesso dall’esterno verso il prodotto stoccato all’interno.

Ultra‐Low Intensity Continuous Wave Laser Ablation Propulsion With Graphene‐Engineered Wood

Advanced Science, EarlyView.
Graphene delignified wood converts continuous wave laser energy into thrust. Laser propulsion experiments in vacuum reveal the lowest laser ablation threshold intensities and the greatest density‐normalized specific impulse in literature. The results highlight graphene delignified wood as a potential efficient, sustainable, strong, and lightweight ...

Mixing‐Driven Defects and Composition Evolution in Multi‐Material Metal Additive Manufacturing

Advanced Science, EarlyView.
Operando synchrotron X‐ray imaging coupled with high‐fidelity multiphysics modeling uncovers how inter‐material mixing reshapes keyhole dynamics and drives distinct pore‐formation pathways in multi‐material laser powder bed fusion (LPBF). Composition‐dependent instabilities trigger defects, whereas rescanning suppresses porosity and homogenizes Cu ...
