Summary: By using carbon nanotubes-tellurium-PEDOT:PSS nanocomposites, it is possible to achieve ultra-low thermal conductivity at high CNT content, which is understood through quantitative mappings of thermal conductivity in micro-scale interface regions. Moreover, the formation of highly conductive layers at the interfaces of Te PEDOT:PSS and CNTs PEDOT:PSS can enhance electrical conductivity and Seebeck coefficient simultaneously.

Summary: Oil is utilized as an 'entrance door' to load carbon-based fillers of various sizes and dimensionalities, enhancing the properties of rubber composite materials. The CNT-loaded system demonstrates the best mechanical properties enhancement, while a system loaded with both graphite and GNP shows the highest enhancement in thermal conductivity. The overall relative efficiency index indicates that the CNT-loaded system is the most efficient in enhancing properties at low filler concentrations.

Summary: In this study, an improved thermal conductive SR composite was successfully synthesized by adding nanodiamond (ND) and boron nitride (BN) as composite thermal conductivity fillers to the terminal hydroxyl functional group of SR. The SR composite filled with 6 phr ND and 70 phr BN showed significantly enhanced thermal conductivity, better thermal stability, and mechanical properties compared to those filled with a single filler. This composite material demonstrated superior performance indicators compared to similar products currently available on the market.

Summary: Nowadays, the heat transfer problem between devices has become more problematic as electronics become more refined and integrated, making thermal interface materials with good thermal conductivity increasingly critical. In this paper, thermally conductive composites are prepared using silicone rubber (SR) and boron nitride coated with tannic acid and grafted with hexamethyldisilazane (BN@TA-HMDS). The modified BN@TA-HMDS and silicone rubber show excellent compatibility and dispersion within the silicone rubber matrix. When the mass part of BN@TA-HMDS is 50, the composites exhibit a thermal conductivity of 0.735 W/m·K, which is about 6 times higher than that of pure SR. Moreover, the viscosity of the composite before cured is significantly reduced, being only 1/50 of the BN/SR at the same ratio when the mass part of BN@TA-HMDS is 50. This work provides valuable guidance for mass filling to enhance the material's thermal conductivity.

Summary: A sponge rubber nanocomposite based on SBR/nanoclay or nano-calcium carbonate fillers was produced by roll milling, with nanoparticles examined using various techniques. The nanocomposites' properties, including foaming degree, tensile strength, elongation at break, and thermal conductivity, were investigated, revealing that foam composites containing nano-CaCO3 had the best mechanical properties but lowest foaming degree. The foam containing MMT showed intermediate behavior, while the foam containing CaCO3 nanoparticles had high thermal conductivity.

Summary: This study investigates the influence of conductive fillers on the rheological behavior and electrical conductivity of multi-functional shear thickening fluids (M-STFs) using the response surface methodology (RSM). The results show that conductive fillers play a significant role in the rheological properties and electrical conductivity of M-STFs. The effects of filler content, temperature, and type of fillers on the electrical resistance and rheological behavior of M-STFs are studied. The findings provide new insights for the development of novel STF-based systems with multi-functional properties.

Summary: This study aimed to investigate the polyphenolic extract from rice husk's ability to counteract protein glycation at different stages, using in vitro assays. Microwave-assisted extraction was used to recover the polyphenols, and the extraction parameters were optimized. The extract showed dose-dependent activity in inhibiting fructosamine formation in the early stage of glycation and almost completely inhibited advanced glycation end products (AGEs) in the middle stage, as well as demonstrating good trapping ability against alpha-dicarbonyl intermediates. The presence of ten polyphenols, mainly hydroxycinnamic acids and flavonoids, supported the results.

Summary: In this study, multifunctional boron carbide nanoparticles stabilized with polyacrylic acid (PAA) and a gadolinium (Gd)-rich solid phase were synthesized and their biological activity was evaluated. The incorporation of a fluorophore (DiI) allowed for confocal microscopy imaging of the nanoparticles. Novel correlative microscopy techniques were employed to analyze the interaction and activity of these fluorescent Gd-containing B4C nanoparticles (FGdBNPs) with cultured cells. The results indicate that these nanoparticles have the potential to achieve high boron concentration in tumor cells.

Summary: Ladder-like polysilsesquioxanes (LPSQs) with a double-stranded siloxane backbone can be used to prepare functional nanocomposites (NCs) by blending with organic polymers or exploiting the dispersion of inorganic fillers. The addition of TiO2 nanoparticles reduces the polymerization capacity of the organic side-chains and changes the organization of ladder chains in the polymerized LPMASQ. This research approach can be applied to other composite systems and provide insights for a better design of such materials.

Summary: The effect of processing method and sepiolite filler amount on the microstructure of starch-based nanocomposites was investigated. The processing method disrupted the rigid lattice structure of semicrystalline starch, resulting in amorphous flexible films with high transparency and good thermal resistance. The microstructure of the bio-nanocomposites depended on complex interactions among sepiolite, glycerol, and starch chains, which also affected the final properties of the composite materials.

Summary: Circular bioeconomy methodologies were applied to examine value-adding entrepreneurial activities for rice industry by-products (RIB) in Sri Lanka. Biochar production was identified as the optimal valorization strategy for RIB management. The development of a sustainable business model for biochar production was done based on commercial motivations and value addition in the manufacturing processes. Successful implementation of sustainable circular business models requires subsidies, regulations, collective actions, and marketing strategies.

Summary: This study compares the skeletal calcification pattern of batoid Raja asterias with mammalian Homo sapiens and teleost Xiphias gladius. Different techniques were used, including histology, histochemistry, SEM/EDAX analysis, TGA, DSC, and FTIR. The calcified cartilage of R. asterias diverges from the ossification models of H. sapiens and X. gladius, showing higher water release and more amorphous bioapatite. In R. asterias, the calcified cartilage remains un-remodeled throughout the lifespan, while in endochondral ossification, fetal calcified cartilage is replaced by bone matrix.

Summary: Due to decreasing rainfall, the problem of drought is becoming increasingly alarming. Direct reuse of treated wastewater, in compliance with current legislation, could be a solution to address water scarcity. This study analyzed wastewater treatment plants in the Lombardy region of Italy to identify the most critical parameters in their effluents. The use of biochar filters as a means of final adsorption for wastewater treatment plant effluents could improve water quality for direct reuse. The study also investigated the efficiency of removing various pollutants from real wastewater using batch adsorption tests.
