Advanced Functional Materials, EarlyView.Multifunctional solid polymer electrolyte (SPE) films integrating intrinsic self‐healing, mechanical stretchability, and dual photo‐ and pH‐responsive ionic conductivity are developed. Constructed from thermoplastic polyurethane (TPU) and hydrogen‐bonded poly(thiourea triethylene glycol) (PTUEG3), these films form a dynamic supramolecular network ...

Advanced Functional Materials, EarlyView.An atomically dispersed Ni catalyst featuring Ni‐N4 coordination is developed as a sulfur host for nonaqueous Zn─S batteries. This configuration modulates the electronic structure to lower activation barriers during rate‐limiting steps and promotes a robust ZnF2‐rich cathode‐electrolyte interphase, thereby accelerating sulfur redox kinetics ...

Solution‐Processed Mn‐Doped 2d Perovskite Wavelength Shifters for Noble‐Liquid Photon Detection
Advanced Functional Materials, EarlyView.Solution‐processed Mn2+‐doped PEA2PbBr4 two‐dimensional perovskite films are demonstrated as large‐area wavelength shifters for noble‐liquid photon detectors. Mn2+ incorporation introduces a broad emission band at ∼620 nm with a large Stokes shift, suppressing self‐absorption and matching SiPM sensitivity.

Simulation of gas explosions [PDF]
Modeling, Identification and Control: A Norwegian Research Bulletin, 1989 Gas explosion hazard assessments in flammable gas handling operations both offshore and onshore are crucial in order to obtain an acceptable level of safety. In order to perform such assessments good predictive tools are needed, which take account of the relevant parameters, such as geometrical design variables and gas cloud type and distribution.
