Abstract Quantum dots (QD), mixed with carbon materials, have gained increasing interest in the last few years as electrocatalysts due to their outstanding properties, such excellent catalytic activity and good thermodynamic stabilities. However, most QD‐carbon hybrids show lower activities than that theoretically predicted aggregation of nanostructures during processing. Herein, biomass is use...

We present a density functional theory analysis of the negatively charged nitrogen-vacancy (${\mathrm{NV}}^{\ensuremath{-}}$) defect complex in diamond located vicinity (111)- or (100)-oriented surfaces with mixed (N,H)-terminations. assess stability and electronic properties ${\mathrm{NV}}^{\ensuremath{-}}$ center, we study their dependence on H:N ratio surface termination. The formation energ...

ABSTRACT Determining nitrogen (N) accumulation and export by common bean as a function of straw the splitting this nutrient is very important, aiming at management sustainability agricultural systems. This study aimed to determine N Zea mays Urochloa ruziziensis grass (maize, maize/U. intercropping U. ruziziensis) top-dressing fertilization. The experiment was conducted in Jaboticabal-SP-Brazil...
