A crystalline block copolymer of poly(ethylene-block-ethylene oxide) (PE-b-PEO) was successfully grafted onto a carbon black surface by direct condensation of its terminal hydroxyl groups with carboxyl groups on the surface using N,N′-dicyclohexylcarbodiimide as a condensing agent. The electric resistance of the compo…

The thermodynamic properties of anion exchange on a chloride-intercalated zinc–aluminium layered double hydroxide have been studied at 298.15 K. The heats for total exchange of Cl− for F−, Br−, I−, OH−, NO3−, and SO42− have been determined by microcalorimetry and the standard molar enthalpies of these exchange reactio…

Recently the authors have presented a method to prepare activated carbon fiber with high bulk density (HD-ACF) without using any binders. The possibility of using the HD-ACF as an electrode for electric double‐layer capacitors (EDLCs) was examined in this paper. The capacitance of the EDLC with the HD-ACF electrode in…

The phase-field method is used to simulate the two-dimensional growth of a dendritic crystal in a forced flow. The selection of the velocity and shape of the dendrite tip is investigated as a function of flow rate, growth direction relative to the flow, as well as anisotropy strength, and the results for the upstream…

The effects of poly vinyl alcohol (PVA)/Chitosan/Fibroin (PCF)-blended sponge on wound healing in rats were investigated. We excised the skin of a rat, including the dermis, approximately 2 x 2 cm in size. The wound was covered with PCF-blended spongy sheets. The spongy sheets absorbed the exudate, and gained flexibil…
