Corrosion Resistance of Steel/Zinc with Silicate Nanoparticles/Polyurethane Paint Systems in NaCl Solution [PDF]

, 2012
Surface characteristics and corrosion behaviour of bare electrogalvanized steel coated with polymer/nano-silicate particles added to the electrogalvanizing bath were studied by scanning electron microscopy (SEM), energy dispersive spectrometer (EDXS) and

Search for Magnetic Monopoles Trapped in Matter [PDF]

, 1995
There have been many searches for magnetic monopoles in flight, but few for monopoles in matter. We have searched for magnetic monopoles in meteorites, schists, ferromanganese nodules, iron ores and other materials.

Molecular spin-liquid state in spin-3/2 frustrated spinel HgCr$_2$O$_4$

, 2011
A hexamer-type spin excitation seen in spinel chromates $A$Cr$_2$O$_4$ ($A$ = Mg, Zn, or Cd) is the representative spin-liquid-like state caused by geometrical frustration.

AC - conductivity studies on Y1-xBixCrO3 solid solution [PDF]

, 2017
YCrO3 and the substitution of Bi+3(6s2) in the Y-site were synthesized by the sol gel process. The conductivity measurements using dielectric spectroscopy reveals that conductivity increases with increase of composition.

Progress in eco-friendly aerospace coatings: the future beyond chromates

Journal of Electrochemical Science and Engineering
Aluminium alloys have a good strength-to-weight ratio and low density, but they are not impervious to corrosion. Therefore, it is necessary to evaluate their corrosion performance in the atmospheric environment.

Hierarchically Porous Nitrogen‐Doped Carbon with High Conductivity for Rapid and Efficient Cr(VI) Reduction

Advanced Science, EarlyView.
The d‐PNC(1100, 10%) catalyst, synthesized via a zinc‐based ionic liquid self‐sacrificing pore‐forming strategy to create a defect‐rich, hierarchical, nitrogen‐doped porous structure, enhances conductivity, promotes rapid mass transfer and synergistic catalytic activity, driving efficient Cr(VI) reduction in OA solution to generate Cr(III)‐OA complexes.

Review of recent advances in the design, synthesis, and modification of biochar for remediation of heavy metal pollution in water

The Canadian Journal of Chemical Engineering, EarlyView.
Research frontiers in using biochar for heavy metal remediation. Abstract Heavy metal contamination of water has long been a serious environmental issue. Biochar and biochar‐based composites are emerging as effective and sustainable solutions for heavy metal removal due to their strong adsorption abilities and environmentally friendly nature.
