Carbon dioxide (CO) conversion to value-added chemicals is an attractive solution to reduce globally accelerating CO emissions. Among the non-precious and abundant metals tested so far, copper (Cu) is one of the best electrocatalysts to convert CO into more than thirty different hydrocarbons and alcohols. However, the selectivity for desired products is often too low.

Electrochemical CO reduction reactions can lead to high value-added chemical and materials production while helping decrease anthropogenic CO emissions. Copper metal clusters can reduce CO to more than thirty different hydrocarbons and oxygenates yet they lack the required selectivity. We present a computational characterization of the role of nano-structuring and alloying in Cu-based catalysts on the activity and selectivity of CO reduction to generate the following one-carbon products: carbon monoxide (CO), formic acid (HCOOH), formaldehyde (HC=O), methanol (CHOH) and methane (CH).

Hexagonal boron nitride (h-BN), with insulating band gap (> 6 eV) 2D material, has attracted extensive attentions. To discover potential applications in optoelectronic devices, modulation in electrical conductivity (n or p type) plays a significant role. In this paper, the structural and electronic properties of energetically stable doped boron nitride monolayer via ab initio calculations have been reported.

Background: Calcification has been well reported in basal ganglia and it grows rapidly in globus pallidus (GP) followed by putamen (PUT) and caudate nucleus because of their high metabolic rate and displays high susceptibility effects. Therefore, the current study focused on magnetic susceptibility effect of calcium content in normal and diseased tissue due to metabolic changes.

Objectives: To evaluate calcium content in GP and PUT structures of multiple sclerosis (MS) patients versus healthy subjects using quantitative susceptibility mapping.
