Three vanadium-based catalysts were used to remove high concentrations of nitrogen oxides, and the catalysts’ performance de-NOx anti-H2O under NOx investigated. The V-Mo-W/TiO2 tested 1500 mL/min gas flow (GHSV = 500 h−1, 2.4% NO2, 4.78% NH3, 13% O2, 4% H2O, 5% CO2) characterized by BET, SEM, EDS, XRD, XPS, H2-TPR, NH3-TPD; then, their physical chemical properties analyzed. results showed that...

Improving cell infiltration into engineered scaffolds and decelluarized tissue is needed for developing new effective technologies in regenerative medicine engineering. Significant challenges associated with populating these structures cells have persisted many years. Here we describe a 3D bioprinting method creating precise from natural extracellular matrix at low concentrations that facilitat...

520 efficient. One strain could barely grow at P concentration below 1 μM; this strain could have difficulty colonizing P-deficient soils or normal rhizospheres. Large differences in tolerance to low P among strains may be agronomically important. The technique could be simplified for routine screening of strains; and its operation at submicromolar concentrations could be improved for research ...
