Anomalous Stiffening of a Conjugated Polymer During Electrochemical Oxidation

Advanced Functional Materials, EarlyView.
The electromechanical response of a thienothiophene‐based conjugated polymer with triethylene glycol side chains is investigated. Electrochemical nanoindentation and atomic force microscopy reveal a modest and reversible increase in elastic modulus at room temperature upon electrochemical oxidation.

Toward Scalable Solutions for Silver‐Based Gas Diffusion Electrode Fabrication for the Electrochemical Conversion of CO2 – A Perspective

Advanced Functional Materials, EarlyView.
In this study, the preparation techniques for silver‐based gas diffusion electrodes used for the electrochemical reduction of carbon dioxide (eCO2R) are systematically reviewed and compared with respect to their scalability. In addition, physics‐based and data‐driven modeling approaches are discussed, and a perspective is given on how modeling can aid ...

EQUILIBRIUM AND KINETIC STUDY OF ADSORPTION OF NICKEL FROM AQUEOUS SOLUTION ONTO BAEL TREE LEAF POWDER [PDF]

, 2009
The ability of bael tree (BT) leaf powder to adsorb nickel, Ni2+, from aqueous solutions has been investigated through batch experiments. The Ni2+ adsorption was found to be dependent on adsorbent dosage, initial concentration and contact time. All batch

Polyferrocene‐Based Cubosomes: Conversion to Magnetic Mesoporous Microparticles, Supramolecular Modification, and Oxidation Response

Advanced Functional Materials, EarlyView.
Polyferrocene block copolymers are synthesized and assembled into micron‐sized polymer cubosomes with double diamond lattice and pore diameter of ≈30 nm. The ferrocene functionality is retained within the polymer cubosome wall as demonstrated on supramolecular modification, and oxidative disassembly.

Spatially Tailorable Liquid Crystalline Elastomer Alignment During Digital Light Process 3D Printing

Advanced Functional Materials, EarlyView.
Here, we report the fabrication of 3D printable liquid crystalline elastomer (LCE) structures with spatially tailorable alignment domains within the same layer. This work addresses the long‐standing challenge of preparing complex 3D LCE architectures with patterned functional domains to achieve nonlinear deformations. Fabrication of multi‐domains in 3D

Linearized Equations of Pseudo Second-order Kinetic for the Adsorption of Pb(II) on Pistacia Atlantica Shells

IERI Procedia, 2013
AbstractIn the present study, four forms of pseudo second (PS) order kinetic linearized equations for the adsorption of Pb(II) by pistacia atlantica shells were investigated. Kinetic parameters determined for all forms of linearized equations and results obtained from this study show that not only the parameters obtained can be differed but also based ...
