X-ray Burst Oscillations: From Flame Spreading to the Cooling Wake

, 2016
Type I X-ray bursts are thermonuclear flashes observed from the surfaces of accreting neutron stars (NSs) in Low Mass X-ray Binaries. Oscillations have been observed during the rise and/or decay of some of these X-ray bursts.

Characteristics of diffusion flames with accelerated motion

Thermal Science, 2016
The aim of this work is to present an experiment to study the characteristics of a laminar diffusion flame under acceleration. A Bunsen burner (nozzle diameter 8 mm), using liquefied petroleum gas as its fuel, was ignited under acceleration.

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

Effects of inert gas addition on the characteristics of spherically expanding hydrogen-methane-air premixed flames in closed combustion vessels

Journal of Thermal Science and Technology
In the serious accident at Fukushima Daiichi Nuclear Power Station, the presence of steam together with flammable organic compounds affected the hydrogen explosion. To investigate the effects of addition of inert gas, i.e.

Polar Lattice‐Distorted Motifs Enable Synergy of Local Polarization/Dipole Fields for Concurrent Glyphosate Wastewater Remediation and CO Evolution

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.

Direct Numerical Simulations of Type Ia Supernovae Flames II: The Rayleigh-Taylor Instability

, 2004
A Type Ia supernova explosion likely begins as a nuclear runaway near the center of a carbon-oxygen white dwarf. The outward propagating flame is unstable to the Landau-Darrieus, Rayleigh-Taylor, and Kelvin-Helmholtz instabilities, which serve to ...

Non‐Destructive Hydrophobic Engineering of Inverse Catalysts for Methanol Synthesis from CO2

Advanced Science, EarlyView.
In this study, we report a non‐destructive hydrophobic modification strategy for ZrO2/Cu catalyst through physical mixing with PDVB. The optimized ZrO2/Cu‐PDVB catalyst achieves a methanol space‐time yield of 920.10 mgCH3OH gcat−1 h−1 under mild conditions, outperforming the unmodified catalyst by 30 %.

Multifunctional Phosphate Monomer Enabling LiNO3 Solvation and In Situ Formation of Flame‐Retardant Gel Polymer Electrolyte for High‐Voltage Lithium Metal Batteries

Advanced Science, EarlyView.
A phosphorus‐containing multifunctional monomer is successfully synthesized to simultaneously enable the dissolution of lithium nitrate in ester‐based electrolytes and in situ form a flame‐retardant gel polymer electrolyte (GPE). The formed GPE effectively stabilizes the structures of both the cathode and anode, thereby achieving superior long‐term ...
