Abstract Bacteria in nature encounter substrates at widely varying concentrations, yet studies of bacterial physiology have focused more on nutrient type than concentration, partly due to challenges maintaining low concentrations. We developed a Millifluidic Continuous Culture Device (MCCD) culture bacteria under precisely controlled conditions, including very manner suitable for proteomic analysis. Using the MCCD, we cultured Escherichia coli with mixture amino acids as sole carbon source...
It is crucial to make Si wafer surfaces ultraclean in order realize low‐temperature processing and high‐selectivity ultralarge scale integrated production. The surface must be perfectly free from particles, organic materials, metallic impurities, native oxides, microroughness, adsorbed molecular impurities. Metallic contamination, the major type of contaminants overcome, has a fatal effect on device characteristics suppressed at least below 1010 atom/cm2. current dry processes, such as...
Ultrapure water production technology is basic to ultralarge scale integrated (ULSI) manufacturing. To improve cleanliness on the Si surface, impurities in ultrapure must be reduced. In a study of ozone behavior reaction order decomposition was 1.5 inside oxidation‐passivated stainless steel tubing. However, plastic tubing not even when including organic materials were suppressed an extremely low level. Oxidation‐passivated SUS316L resisted elution and attack excellently. perform continuous...
Abstract. Zinc (Zn) is an essential micronutrient for most eukaryotic phytoplankton. Zn uptake by phytoplankton within the euphotic zone results in nutrient-like dissolved (dZn) profiles with a large dynamic range. The combination of key biochemical uses and vertical gradients dZn implies potential rapid rates removal from surface ocean. However, due to ease contamination at sea, direct measurements natural environments have not been previously made. To investigate demand cadmium (dCd;...
