A vertical silicon-graphene-germanium transistor
Nature Communications, 2019 Graphene-base transistors were originally proposed for high-frequency applications, but the height of the emitter potential barrier limits the transistor performance towards the THz range. Here, the authors fabricate a vertical silicon-graphene-germanium

FEBS Open Bio, EarlyView.Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

Novel methods in trace metal detoxification [PDF]
, 1988 Two putative methods to deal with the problems caused by toxic trace metals were examined. Firstly, Escherichia coli cells into which had been cloned a gene thought to encode a metal-binding protein were examined.

Canopy influence on trace metal atmospheric inputs on forest ecosystems: Speciation in throughfall [PDF]
, 2010 Trace Metal (TM: Cd, Cu, Ni, Pb, Sb and Zn) atmospheric inputs have been studied on six forested sites. In order to evaluate canopy interaction with atmospheric inputs, TM have been measured in both Open Field Precipitation (OFP) and Throughfall (TF ...

Versatile vector tools for efficient protein screening across multiple expression systems
FEBS Open Bio, EarlyView.A unified vector toolkit enables rapid protein expression screening across E. coli, insect, and mammalian cells. A single primer pair amplifies the target gene, which is inserted into any vector via a standardized interface. This streamlined workflow eliminates repeated cloning steps, accelerating the identification of optimal expression conditions for

Micro segregation rates of liquid Fe-Ni-S metal in natural silicate-metal systems: A combined experimental and numerical study [PDF]
, 2011 We present results of an image‐based numerical model aimed at quantifying the microsegregation and flow of liquid metal in meteorites prior to the onset of silicate melting. The sample material is the H6 chondrite Kernouvé.
