Summary: Due to the distinction of (111) and (100) faces, metal additives preferentially form interface layers on diamond particles in copper/diamond composites. The interface layers formed can affect the thermal conductivity of the composites. Copper-55 vol%(Cr-coated) diamond composites were produced by hot forging under different temperatures, and the evolution of the carbide interface formation on diamond surfaces was studied. Different behavior was observed below and above 850 degrees C, and the thermal conductivity was highest for the sample hot forged at 1050 degrees C.

Summary: This study explores the relationship between network morphology and conductivity in 2D nanosheets networks by controllably altering the morphology through a combination of heat and pressure. The increase in network conductivity is linked to an increase in network connectivity and a reduction in junction resistance as the porosity is decreased, leading to significant improvements in conductivity. Conductivity anisotropy changes with porosity, with a potential decrease from 3000 at low porosity to 1 at high porosity.

Summary: The tradeoff between ionic conductivity and mechanical robustness of a polymer electrolyte can be alleviated by selectively plasticizing the ion-conductive block. By introducing TEGDME plasticizer into a PS-PEO-PS block copolymer electrolyte, the ionic conductivity is increased while maintaining a relatively high storage modulus.

Summary: This study investigates the engineering properties of a novel vertical cutoff wall backfill composed of reactive magnesia (MgO)-activated ground granulated blast furnace slag (GGBS), sodium-activated calcium bentonite amended with polyacrylamide cellulose (PAC), and clean sand (MSBS-PAC). Compared to backfills composed of MSBS, the MSBS-PAC backfill shows lower pH, dry density, higher void ratio, lower unconfined compressive strength and strain at failure, and lower hydraulic conductivity after 28-day and 90-day curing. The lower hydraulic conductivity of MSBS-PAC backfill is attributed to the improvement of pore structure and pore fluid environment by PAC amendment.

Summary: Conductive composite cryogels were prepared by simultaneous oxidation coupling polymerization of aniline and radical polymerization of acrylamide, achieving the uniform distribution of PANI in the polymer matrix. The resulting cryogels showed adjustable electrical conductivity due to the acidic doping of PANI, making them suitable for resistive gas sensor electrodes. By adjusting the content of PANI, sheet thickness, and dry/wet state, the response sensitivity and recovery properties of the sensor could be influenced.

Summary: Ionic conductivity and conductivity mapping of PEO/CuSO4 composite films were investigated to study the effect of Cu+2 and SO4-2 ion complexation on PEO matrix. The addition of CuSO4 decreased the crystallinity degree of PEO films and increased segmental motion of PEO, resulting in enhanced ionic conductivity and charge diffusion. Cu+2 ions formed complex with ether oxygen in PEO films, while SO4-2 ions behaved as free ions in the polymer matrix. Introducing CuSO4 also improved the thermal stability of the composite films.

Summary: The patterns formed in natural biochemical and geochemical media are not homogeneous, while artificial systems trying to mimic nature lack the complexity of the natural ones. Liesegang patterns are artificial reaction-diffusion precipitate patterns that can be formed in hydrogels. This study demonstrates that different gel concentration boundaries can cause refractions of the pattern waves and changes in the band spacings.

Summary: The study investigated the removal of nickel(ii) ions using two sizes of graphene oxide nanoparticles (GO - 450 nm and GO - 200 nm). GO - 200 nm showed better removal efficiency compared to GO - 450 nm due to increased surface area. The preparation of graphite oxide by oxidation-reduction reaction and reduction of particle size via sonication were key steps in the study, along with analyzing the surface properties of the GO particles using FTIR spectroscopy and SEM.

Summary: This study outlines the fabrication and characterization of pamidronate (PDS) embedded nanofibrous scaffolds based on polycaprolactone/polycaprolactone-polyethyleneglycol-polycaprolactone (PCL/CEC) blends for osteoporotic bone defect management. The electrospinning technique was utilized to fabricate PDS-loaded scaffolds, and the effect of PDS on the blends was evaluated in terms of surface morphology, wettability, biodegradability, and in vitro cytocompatibility. The results showed that the PCL/CEC-PDS scaffolds had a fibroporous architecture, appropriate mechanical properties, and the ability to support cell growth, indicating their potential for managing osteoporotic bone defects.
