POM‐Based Water Splitting Catalyst Under Acid Conditions Driven by Its Assembly on Carbon Nanotubes

Advanced Materials, EarlyView.
A newly‐engineered POM‐based electrocatalyst incorporating non‐innocent counter cations exhibits fast kinetics for either the OER or HER under strongly acidic conditions (1 m H2SO4), depending on whether it is assembled on carbon nanotubes (1@CNT) or physically mixed with them (1/CNT). In water‐splitting tests using a two‐electrode setup, these systems

Flexoelectrically Induced Polar Topology in Twisted SrTiO3 Membranes

Advanced Materials, EarlyView.
Twisted SrTiO3 bilayers host polar vortices of flexoelectric origin, revealed through combined experiment and theory. By reconstructing polarization from the toroidal moment of strain gradients, the work establishes a 3D chiral state with broken inversion and mirror symmetries.

Cation Exchange Capacity Predictions [PDF]

, 1984
Cation exchange is a property of the soil in which the soil colloids gain and lose cations to and from the soil solution. Cations commonly exchanged are calcium (Ca+2), magnesium (Mg+2), sodium (Na+), potassium (K+), hydrogen (H+), and ammonium (NH ...

CO2 to fuel: Role of polymer electrolytes on efficiency and selectivity

Carbon Capture Science & Technology
Global primary energy consumption, which heavily depends on fossil fuels, is on track for depletion, with projections suggesting exhaustion by 2100. This trajectory is further compounded by the persistent rise in atmospheric CO2 levels, currently at 420 ...

Polymer Network Structure and Response to Compresssion of Carboxylic Cation-Exchange Resins

The mechanical tests in compression of swollen carboxylic cation-exchange resins with different structure and composition have been done. Cation-exchange resins consist of methacrylic acid and cross-linking agent units or acrylic and methacrylic acids ...

Atomistic Mechanisms Triggered by Joule Heating Effects in Metallic Cu‐Bi Nanowires for Spintronics

Advanced Materials, EarlyView.
Bi doped metallic Cu nanowires are promising for spintronics thanks to the stabilization of a giant spin Hall effect. However, heat resulting from current injection forces Bi to leave solution, forcing segregation into monoatomic decorations which evolve into coherent crystalline aggregates.

Preparation of porous PMMA/Na+-montmorillonite cation-exchange membranes for cationic dye adsorption

, 2014
Porous PMMA/Na+-montmorillonite (MMT) cation-exchange membranes were successfully prepared by entrapment method in this study. One approach (simple mixing) was to mix commercial PMMA polymer with Na+-MMT clays in solvent for membrane preparation ...
