The article discusses the development of highly active dinuclear cobalt complexes that facilitate the solvent-free cycloaddition of CO2 to epoxides at ambient pressure. This advancement in catalysis could have significant implications for environmental science and chemistry, particularly in the efficient utilization of CO2.

The UAE vs Zimbabwe cricket series in 2019 began on April 10th, with the UAE playing four ODIs against Zimbabwe over a two-week tour. Live streaming was broadcast by Village Sports Live Official YouTube Channel, with other TV channels also telecasting the series in various countries. The series results included Zimbabwe winning the matches on April 10th, 12th by the D/L method, and 14th by 131 runs.

A study introduces an innovative technique using atmospheric-pressure chemical vapor deposition (APCVD) to produce TiO2 photoanodes in 5 minutes for sustainable hydrogen production. The photoanode shows exceptional photoelectrochemical water-splitting performance with a photocurrent density of 2.06 mA cm−2 at 1.23 V RHE and sustained operation for 16 hours. The success is attributed to the anatase–rutile phase-junction, oxygen vacancies, and a bifrustum nanoparticle–nanoflake structure. Density functional theory calculations reveal that the water-splitting reaction occurs at undercoordinated Ti and O atoms, with charge transfer enhancing the hydrogen evolution reaction (HER) performance in the heterojunction.

The study compares the Autler–Townes (AT)-splitting in various doped crystals, finding that the AT-splitting in ${{ m Pr}^{3 + }}{:}{{ m Y}_2}{{ m SiO}_5}$ is stronger than in other crystals. The stronger dressing effect in YSO is attributed to its ${{ m C}_{2h}}$ symmetry and nondegeneracy. The research explores the relationship between spectral AT-splitting (SAT-splitting) and temporal AT-splitting (TAT-splitting), concluding that TAT-splitting depends on the dressing effect and phonon-assisted nonradiative transition, while SAT-splitting results solely from the dressing effect. Based on these findings, a model for an optical router and transistor is proposed, utilizing the SAT- and TAT-splitting for the router and a switch from bright to dark dressed states for the transistor.

Iron oxide nanoparticles coated with graphitic carbon nitride exhibit enhanced electrocatalytic activity and stability for hydrogen evolution reaction in acidic environments, with significant improvements over pristine graphitic carbon nitride. Density functional theory calculations corroborate experimental findings, indicating electron transfer from iron oxide to graphitic carbon nitride as the mechanism for improved performance.

Five new Rohingya mass graves have been uncovered in Burma's Rakhine state, adding to evidence of a military crackdown that may constitute crimes against humanity or genocide. The UN special envoy on human rights in Burma, Yanghee Lee, indicated signs of genocide but awaits a tribunal's verdict. Despite plans for repatriation of 750,000 refugees from Bangladesh, many are too traumatized to return, fearing further persecution. The UNHCR stresses that repatriation should be voluntary and informed. Rohingya activists and organizations demand justice and policy changes before repatriation, while Human Rights Watch emphasizes the need for international action in response to the new mass grave findings.
