Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

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 ...

The effects of rolling deformation on microstructure and mechanical properties of cold spraying Ti

Discover Materials
Due to porosity and lack of metallurgical bonding, cold-sprayed Ti (CS-Ti) shows insufficient mechanical properties, especially plasticity. Here we investigate the effect of rolling deformation on the microstructure and mechanical properties of CS-Ti ...

Metal enrichment processes

, 2008
There are many processes that can transport gas from the galaxies to their environment and enrich the environment in this way with metals. These metal enrichment processes have a large influence on the evolution of both the galaxies and their environment.

Source of the optical red-slope in iron-rich meteorites [PDF]

The relationship between ordinary chondrites and S-type asteroids is an unresolved issue in meteorite science. S-type asteroids exhibit a positively red-sloped spectrum that is interpreted to indicate the presence of elemental iron on the surfaces.

Surface Science of Metal Clusters.

Hyomen Kagaku, 1993
近年,数原子から1000原子程度から構成される金属クラスターは,固体金属と原子とを結ぶ中間相として,また固体表面のモデルとして注目され,電子構造や幾何構造,さらには吸着反応性が明らかにされてきた。金属クラスターの吸着反応は,クラスターの電子状態と幾何構造との両者に支配されており,吸着反応を各原子数ごとに調べるとクラスターの構造が明らかにできる。また,合金クラスターの吸着反応では,イオン化ポテンシャルを指標とすることにより,それぞれ元素の混ざり方を知ることができる。コバルトとバナジウム(ConVm)またはナトリウム(ConNam)の二つの合金クラスターでは,金属元素同士は混ざり合いながら,安定な幾何構造へ再編されるが,シリコンとナトリウムのクラスター(SinNam)では ...
