Recent efforts to design chemoselective catalysts have focused on modifying the surface of metal nanoparticle materials having tunable properties. However, precise control over the surface properties of base-metal oxide catalysts remains a challenge. Here, we show that green modification of the surface ...
Catalytic upgrading of ethanol to n-butanol over a novel Ca-Fe modified mixed oxide Mg-Al catalyst from hydrotalcite-base precursor 2022, Catalysis Today Show abstract Disclosing Fast Detection Opportunities with Nanostructured Chemiresistor Gas Sensors Based on Metal Oxides, Carbon, and Transition Metal...
carboxylate groups were used to stabilize the metal centers in the LDH. Electrochemical deposition provided both coordinated and uncoordinated carboxylate ligands through redox reactions occurring near the electrode. NiFe-LDH with trimesic acid ligands was prepared through direct electrochemical deposition on ...
For an acid with density=1.92, the latter equation yields a P2O5content of 75.9%. A calculation of molar P2O5/H2O ratios using this equation produces a value less than the known starting composition of acid prepared at the laboratory where one of the authors (H. Le Q. S-W.) formerly wo...

Metal chelator; pigments.Humic acid is used as a soil supplement in agriculture and human nutritional supplement. It is used to improve the growth and cultivation of crops, citrus, turf, flowers. It is also used to improve the strength of organically-deficient soils. It is utilized to stimulat...
Electrochemical studies showed that the synergy of copper oxide nanoparticles and HKUST-1 in the nanocomposite lead to high electrocatalysis, fast response for catalysis (less than 5 s) with good signal strengths and excellent selectivity toward the oxidation of citric acid (CA). It was also ...
The major mechanism underlying the role of exogenously-sourced nitric oxide (NO; as sodium nitroprusside, SNP: 50.0 µM) and salicylic acid (SA; 0.5 mM) in the presence of 2.0 mM SO4−2 was assessed in heat stress (HS; 40 °C for 6 h daily for 15 days) tolerance in wheat (...
Chemical decontamination, which has been considered the most effective method so far, involves dissolving the corrosion metal oxides using redox reactions [4,5,6,7,8,9]. In order to dissolve magnetite (Fe3O4), a typical corrosion oxide, through a reductive reaction, decontamination processes dev...
(a) the addition of metallic aluminum to a copper(II) nitrate solution results in the precipitation of copper metal and the formation of aluminum ions in solution.(b) metallic copper is added to a dilute solution of nitric acid,gaseous nitrogen(II) oxide is evolved and the solution becames...
