High-pressure structural investigation of several zircon-type orthovanadates

, 2009
Room temperature angle-dispersive x-ray diffraction measurements on zircon-type EuVO4, LuVO4, and ScVO4 were performed up to 27 GPa. In the three compounds we found evidence of a pressure-induced structural phase transformation from zircon to a scheelite-

Corrosion protection of carbon steel by an epoxy resin containing organically modified clay [PDF]

, 2007
This study focusses on the use of montmorillonite clay (MMT) treated with an organic compound (aminotrimethylphosphonic acid (ATMP)) and dispersed in an epoxy resin to improve corrosion protection of carbon steel.

Features of Synthesis, Crystal Structure, Thermal and Electrical Properties, XPS/NEXAFS Study of Pyrochlore-Type Bi₂Cr_0.5Co_0.5Nb₂O_9+Δ

Chemistry
The phase-pure cubic pyrochlore of the Bi2Cr0.5Co0.5Nb2O9+Δ composition can be successfully synthesized by a modified sol–gel method (Pecini method-PM) and a traditional solid-phase method (SPM).

Chromatics: Warm and Cool

Art & Perception
Abstract Artistically, an important bipartition of hues is with respect to their warm–cool quality. What might this correspond to in colorimetric terms? Various interpretations have been suggested, mostly informally. We attempt to compare them quantitatively, using either diverse data available from the literature, or formal means.

π‐Expanded Nitrogen‐Cation (N+)‐Doped Polycyclic Aromatic Hydrocarbons: A Review of Intramolecular Cyclization Routes to Benzo[c]Quinolizinium, Triazinium, Pyridoquinazolinium, and Pyridoquinoxalinium Frameworks

European Journal of Organic Chemistry, Volume 29, Issue 4, January 26, 2026.
This review surveys recent progress in the synthesis of extended aromatic quinolizinium derivatives via intramolecular SNAr and oxidative 6π‐electrocyclization. Conventional thermal approaches are discussed alongside emerging, sustainable activation methods such as electrosynthesis and photochemical processes.

From Heat to Electrons: Bridging Heterogeneous Liquid‐Phase Thermal and Electrocatalytic Oxidation of Ethylene Glycol over Co3O4

Angewandte Chemie, Volume 138, Issue 3, 16 January 2026.
The aerobic liquid‐phase thermal oxidation of ethylene glycol and its electrocatalytic oxidation resulted in the same product distribution using mesostructured Co3O4. Ab initio molecular dynamics simulations reveal analogous surface intermediates requiring Co3+ centers and OH− species with O2 or the anodic potential regenerating the reduced active ...

A Review on MXene Terminations

Advanced Functional Materials, Volume 36, Issue 4, 12 January 2026.
Surface terminations play a decisive role in determining the properties of MXenes. Their coordination, composition and stoichiometry can be tuned both during synthesis and through post synthesis methods to tailor MXenes for optimum performance in applications. This review explores the present understanding of surface terminations.
