Wide Angle X-ray Sky Monitoring for Corroborating non-Electromagnetic Cosmic Transients

, 2010
Gravitational waves (GW) can be emitted from coalescing neutron star (NS) and black hole-neutron star (BH-NS) binaries, which are thought to be the sources of short hard gamma ray bursts (SHBs).

Harnessing Native Al/Si Impurities in Bamboo Black Liquor for Self‐Templated Closed‐Pore Hard Carbon Anodes

Carbon Energy, EarlyView.
A scalable strategy utilizing native impurities in bamboo lignin black liquor is proposed to construct a closed‐pore, rich hard carbon. Controlled impurity removal and high‐temperature reconstruction enable the conversion of open pores into abundant closed pores, thereby promoting sodium cluster storage.

Bright X-ray Flares in Gamma-Ray Burst Afterglows

, 2005
Gamma-ray burst (GRB) afterglows have provided important clues to the nature of these massive explosive events, providing direct information on the nearby environment and indirect information on the central engine that powers the burst.

Wurtzite‐Chalcopyrite Crystal Polymorphism in CuGaS2 Nanoparticles Dictates the Localized Surface Plasmon Resonance

Chemistry – A European Journal, EarlyView.
Crystal phase‐ and size‐selective synthesis of chalcopyrite and wurtzite‐type CuGaS2 NPs was successfully achieved. They exhibited clear LSPR in the NIR region. The extinction coefficient of chalcopyrite was three times higher than that of wurtzite due to its greater symmetry and dipole moment. These results will enable precise control of the plasmonic

Expedient Discovery of a Metallaphotoredox Cyanomethylation for Synthesizing α‐Aryl Nitriles

Chemistry – A European Journal, EarlyView.
A metallaphotoredox cyanomethylation reaction has been developed for the synthesis of valuable α‐aryl nitrile intermediates. The methodology was successfully applied to diverse medicinally‐relevant substrates, providing an expedient route to anti‐cancer Senexin compounds, while also removing the need for toxic cyanide reagents. The mechanism was probed

Anchoring Monolayer TiOx Nanosheets on Gold Nanoparticles Enhances Catalytic Activity for CO Oxidation Depending on the Type of Support

Chemistry – A European Journal, EarlyView.
Monolayer TNS cover Au/SiO2 and Au/CeO2 surfaces, forming Au–TiOx contact structure that serve as active sites for CO oxidation, thereby significantly improving catalytic activity. On Au/SiO2, the Au–TiOx interface was generated through TNS adsorption and calcination, while TNS adsorption solely promoted the Au–TiOx interface formation on Au/CeO2.
