Self‐Adaptive Reflectance Film for Passive Temperature Regulation in Diverse Environments

open access: yesAdvanced Science, EarlyView.
The rising demand for space cooling calls for innovative passive thermal systems. Traditional radiative cooling materials lack efficiency and alignment with cooling needs, limiting their energy‐saving. A smart film (PFSF) that integrates radiative cooling, reflectance tuning, and phase transition, offering adaptable temperature control across climates ...

Analysis of Energy Transfer in the Ignition System for High-Speed Combustion Engines

open access: yesEnergies
In order to produce reliable and reproducible ignition of lean fuel–air mixtures and highly stratified mixtures, it is necessary to ensure a high concentration of spark discharge energy and to provide a strong energy impulse for the triggering of chain ...

On the Modes of Nanosecond Pulsed Plasmas for Combustion Ignition of Quiescent CH₄-Air Mixtures [PDF]

open access: yes
The effect of transient plasma modes on ignition kernel development are discussed here for a quiescent CH4-air combustion model system. A 10 ns high-voltage pulse was applied to a pin-to-pin electrode in lean fuel-air mixtures at room temperature and ...

A Methionine Allocation Nanoregulator for the Suppression of Cancer Stem Cells and Support to the Immune Cells by Epigenetic Regulation

open access: yesAdvanced Science, Volume 12, Issue 15, April 17, 2025.
A nanoregulator interfering with intratumoral methionine competition is designed to deliver oxaliplatin (IV) prodrugs and anti‐Lat4 small interfering RNA to tumor cells. This Pt (IV)‐crosslinked reduction‐sensitive nanoregulator progressively releases drugs within tumor cells and induces immunogenic cell death.

Prediction of Cyclic O6 Molecules Stabilized by Helium under Pressure

open access: yesAdvanced Science, Volume 12, Issue 11, March 20, 2025.
The cyclic O6 molecules may exist due to the presence of analogical S6 and Se6. However, such O6 rings are never achieved due to unfavorable energy. Strikingly, a stable compound of HeO3 is discovered under pressure, consisting of neutral He atoms and O6 molecules.
