EXAMINATION OF THERMAL PROPERTIES OF CARBON-CARBON AND GRAPHATIZED CARBON-CARBON COMPOSITES
Frontiers in Heat and Mass Transfer, 2013 Thermal characterization is essential to the proper assignment of composites to specific applications. Specific heat, thermal diffusivity, and thermal conductivity are critical in the engineering design process and in the analysis of aerospace vehicles, space systems, power generation, transportation systems, and energy storage devices including fuel ...

Advanced Functional Materials, EarlyView.A fluorine‐rich acrylate monomer (PFHEA) was solvent‐free applied to NCM90 and thermally decomposed under Ar to convert residual lithium into LiF and form a pre‐built LiF/fluorinated amorphous carbon (LiF/FC) interphase. The LiF/FC layer suppresses NiO rock‐salt reconstruction and microcrack propagation, lowers interfacial resistance, and improves Li ...

Dual‐Mode Magnetic Elastomer for On‐Demand Motion and Degradation
Advanced Functional Materials, EarlyView.A dual‐mode magnetic elastomer is introduced, enabling DC field‐driven programmable actuation and AC field‐driven magnetothermal degradation. GHz‐range magnetic fields generate ultrafast heating of magnetic nanoparticles that activates cleavage of the silicone elastomer matrix.

Effect of alkali dosage and silicate modulus on carbonation of alkali-activated slag mortars
, 2018 The long-term durability and their mechanisms of alkali-activated cement based materials have remained largely elusive. In this paper, carbonation of alkali-activated slag (AAS) mortars activated by NaOH and waterglass with different alkali dosages and ...

Accelerating Mineral Carbonation Using Carbonic Anhydrase
, 2016 Carbonic anhydrase (CA) enzymes have gained considerable attention for their potential use in carbon dioxide (CO2) capture technologies because they are able to catalyze rapidly the interconversion of aqueous CO2 and bicarbonate.
