Prediction of Zn(V, Nb, Ta)N Monolayers for Optoelectronic Applications.

A new family of ternary nitride materials, Zn(V, Nb, Ta)N monolayers, is predicted. A fabrication mechanism of the Zn(V, Nb, Ta)N monolayers is proposed based on the chemical vapor deposition approach used for their bulk counterparts. The calculations show that these monolayers are thermodynamically and environmentally stable and that the ZnVN monolayer is the most stable and the easiest to synthesize.

First-Principles Prediction of Two-Dimensional BCP and BCP: Structural Stability, Fundamental Properties, and Renewable Energy Applications.

The existence of two novel hybrid two-dimensional (2D) monolayers, 2D BCP and 2D BCP, has been predicted based on the density functional theory calculations. It has been shown that these materials possess structural and thermodynamic stability. 2D BCP is a moderate band gap semiconductor, while 2D BCP is a zero band gap semiconductor.

[Influence of carbohydrate substrate feeding rate on productivity of recombinant Escherichia coli strain].

Effect of different regimes of glucose feeding on growth rate and recombinant protein synthesis of recombinant E. coli was investigated. It was estimated that the selected regime of substrate feeding provided enhanced finished product yield up to 40-50 per cent.

[Consumption of amino acids by Escherichia coli--a producer of recombinant proteins].

The dynamics of amino acid consumption from the medium by Escherichia coli 1864, a strain producing recombinant protein was studied. It was shown that the strain actively used glutamate and aspartate from the medium, which was determined by the leading role of the amino acids in nitrogen metabolism. The strain also consumed threonine, glycine and alanine capable of effectively providing the culture with metabolic energy.
