Numerical study of acoustic oscillations and combustion instabilities in solid propellant rocket [PDF]
, 1997 A numerical analysis of unsteady motions in solid rocket motors has been conducted. A fully coupled implicit scheme based on a dual time-stepping integration algorithm has been adopted to solve the governing equations and associated boundary conditions.

Perspective: Hollow Core Optical Fibres for Ultraviolet and Visible Wavelengths
Advanced Science, EarlyView.Hollow core optical fibres bypass material constraints that limit optical fibres at ultraviolet and visible wavelengths. However, their challenging fabrication has limited their development, and significant gains in performance remain possible. In this perspective we outline approaches to enable the next generation of fibres for shorter wavelengths ...

Atomic Tuning of Metal‐Support Interactions for Pathway‐Selective CO2 Photoreduction on TiO2
Advanced Science, EarlyView.Single‐atom Fe and Cu catalysts anchored on TiO2 steer photocatalytic CO2 reduction toward distinct pathways. Fe sites favor rapid *CO desorption and selective CO formation, whereas Cu sites stabilize *CHO intermediates, enabling deep reduction and C─C coupling. Combined spectroscopy and DFT calculations reveal how metal–support interactions and oxygen

Advanced Science, EarlyView.Photocatalytic treatment of glyphosate herbicide in agricultural wastewater is achieved through the cooperative effect of the local polarization field and dipole field mediated by lattice‐distorted carbon nitride. Glyphosate is completely degraded via selective C─P bond cleavage with a CO evolution rate of 1166 µmol g−1 h−1.
