Electrochemical transformation of limestone into calcium hydroxide and valuable carbonaceous products for decarbonizing cement production.

The cement industry is one of the largest contributors to global CO emissions, which has been paid more attention to the research on converting the CO released by the cement production process. It is extremely challenging to decarbonize the cement industry, as most CO emissions result from the calcination of limestone (CaCO) into CaO and CO. In this work, we demonstrate an electrochemical process that transforms CaCO into portlandite (Ca(OH), a key Portland cement precursor) and valuable carbonaceous products, which integrates electrochemical water splitting and CO reduction reaction with the chemical decomposition of CaCO.

NDUFA8 potentially rescues Wolbachia-induced cytoplasmic incompatibility in Laodelphax striatellus.

The endosymbiont Wolbachia manipulates host reproduction by several strategies, one of the most important of which is cytoplasmic incompatibility (CI). CI can be rescued when Wolbachia-infected males mate with females infected with the same Wolbachia strain. However, the potential rescue mechanism of CI in the small brown planthopper Laodelphax striatellus is unclear.

Selective electrochemical reduction of carbon dioxide to ethylene on a copper hydroxide nitrate nanostructure electrode.

Electrochemical carbon dioxide reduction (CO2 RR) is a promising technology to convert CO2 into valuable carbon-based fuels and chemicals. Copper (Cu) is a unique catalyst for this reaction as it yields substantial hydrocarbon products, but still suffers from low selectivity in aqueous solution. Here, we present a nanostructure Cu@Cu2(OH)3NO3 electrode using a facile molten salt decomposition method (MSDM).

Activating basal plane in NiFe layered double hydroxide by Mn doping for efficient and durable oxygen evolution reaction.

Foreign metal ions with reducing ability were doped into NiFe layered double hydroxides (NiFe-LDHs) to activate the basal plane in NiFe-LDHs for oxygen evolution reaction (OER). Mn-Doped NiFe-LDH array electrode yields a low onset potential of 1.41 V and exhibits outstanding stability.
