Electroactive Liquid Crystal Elastomers as Soft Actuators

Advanced Functional Materials, EarlyView.
Electroactive liquid crystal elastomers (eLCEs) can be actuated via electromechanical, electrochemical, or electrothermal effects. a) Electromechanical effects include Maxwell stress, electrostriction, and the electroclinic effect. b) Electrochemical effects arise from electrode redox reactions.

Sintering Reaction of Sialon Composite.

Journal of the Japan Society of Powder and Powder Metallurgy, 1996
The sintering reaction of sialon composite containing Y-α'-sialon and β'-sialon has been investigated in the system Si3N4-Y2O3-AlN. It is revealed that Y-α'-sialon with higher solubility is formed by the reaction between AIN and liquid phase at lower temperatures, and that Y-α '-sialon with lower solubility is formed by the reaction between Y-α'-sialon

From Waste to Value: Conversion of Calcium Sulfate to Vaterite via Carbon Capture and Storage

Advanced Functional Materials, EarlyView.
This study introduces a new concept for carbon management that relies on the carbonation of industrial gypsum waste and yields phase‐pure vaterite at ambient conditions without any additives. The obtained vaterite is further shown to be a reactive material that develops compressive strength in aqueous suspensions like conventional cements.

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 ...

Hydroxyapatite-coated metals: Interfacial reactions during sintering

Journal of Materials Science: Materials in Medicine, 2005
Electrophoretic deposition (EPD) is a low cost flexible process for producing HA coatings on metal implants. Its main limitation is that it requires heating the coated implant in order to densify the HA. HA typically sinters at a temperature below 1150 degrees C, but metal implants are degraded above 1000 degrees C.

In-operando high-speed microscopy and thermometry of reaction propagation and sintering in a nanocomposite

Nature Communications, 2019
An important proposed mechanism in nanothermites reactions — reactive sintering — plays a significant role on the combustion performance of nanothermites by rapidly melting and coalescing aggregated metal nanoparticles, which increases the initial size ...
