The chemical reactions of transition metal clusters in the gas phase have aroused considerable scientific interest and are also of critical scientific importance. For example, these reactions are involved in the synthesis of single-walled carbon nanotubes, which are considered ideal materials because of their outstanding properties. Alcohol catalytic chemical vapor deposition (ACCVD) is one of ...

Several cobalt(II), copper(II) and nickel(II) complexes of nicotinoylhydrazine-derived compounds were prepared and characterised by physical, spectral and analytical data. These compounds and their complexes have proven to be antibacterial. The screening data show the metal complexes to be more potential/bactericidal than the uncomplexed compounds against one or more bacterial species.

Rare metals have become indispensable for the production of parts such as batteries, motors, and semiconductors, which are important achieving high functionality in products advanced industries decarbonized society xEV (electric vehicles) AI / IoT. As spread is promoted toward a society, demand in-vehicle lithium-ion batteries expected to increase significantly. Therefore, cobalt used positive ...

We report the electrochemical detection of femtomolar amounts of cobalt, iridium, nickel, and iron ions in solution by electrocatalyst formation and amplification. The metal oxides of these ions can be formed electrochemically and can catalyze the oxidation of water. Alternatively, the reduction of metal ions to metals, such as the reduction of IrCl6(3-) to iridium, is capable of electrocatalyt...

A [P44414][Cl]-NaCl-H2O ionic liquid-based aqueous biphasic system shows promising results for the separation of cobalt(II) and nickel(II) by homogeneous liquid-liquid extraction. The extracting phase consists of a hydrophilic ionic liquid that is salted-out by sodium chloride, indicating that there is no need for using hydrophobic ionic liquids.

BACKGROUND Surveillance on common allergens identified by patch testing plays an important role in emerging allergen detection, which leads to both individual and societal level prevention. OBJECTIVE To study the changes in the pattern of contact sensitization and to identify risk factors associated with allergens. METHOD The data of 206 patients who underwent patch testing at King Chulalon...
