The drain characteristics for a FET that you see on a curve tracer are drawn for equal step increases in the VGS values, yet they are spaced further apart as VGS gets closer to zero. Why? A、This is true for only some FET devices, not all. B、The curve depends on the FET device u...
Electrochemical carbon dioxide (CO2) reduction in acid with a nano-structured tandem catalyst achieves high single-pass conversion efficiency and selectivity to useful C–C coupled products, bringing the process closer to commercial viability.
We conduct nonequilibrium molecular dynamics simulations to measure the shear stress sigma, the average inherent structure energy E{IS}, and the effective ... TK Haxton,AJ Liu - 《Physical Review Letters》 被引量: 96发表: 2007年 Temperature dependence of mechanical properties and pressure sensitivi...
The layered square-planar nickelates, Ndn+1NinO2n+2, are an appealing system to tune the electronic properties of square-planar nickelates via dimensionality; indeed, superconductivity was recently observed in Nd6Ni5O12 thin films. Here, we investigate t

sugars were fed to both strains at the rate which enabled maximum protein production with the parental strain. Under these conditions, RUT-C30 produced 12.5 g L−1of extracellular proteins in 168 h (0.07 g L−1h−1), while BR_TrR03 reached a protein concentration of 34.9 g L−1(...
Yeast is a widely used cell factory for the conversion of sugar into fuels, chemicals and pharmaceuticals. Establishing yeast as being autotrophic can enable it to grow solely on CO2and light, and hereby yeast can be used as a wider platform for transition to a sustainable society. ...
Engineering good viruses to improve crop performance Viruses can be engineered to deliver nucleic acids, peptides and proteins for plant trait reprogramming. Building on market approvals and sales of recombinant virus-based biopharmaceuticals for veterinary and human medicine, similar innovations may be ...
