Impact of Silver and Copper Oxide Nanoparticles on Anaerobic Digestion of Sludge and Bacterial Community Structure
On 2025-02-03 by Zainab K. Abdulsada, Richard Kibbee, Juliska Princz, Banu Örmeci @MDPI
Keywords: nanoparticles, anaerobic digestion, bacterial community, inhibition, biogas generation
AI summary: Metal nanoparticles impact anaerobic digestion and bacterial community. Inhibition is seen at higher concentrations. Cell viability initially decreases but recovers over time. Overall bacterial diversity decreases with higher nanoparticle concentrations.
Abstract: The effect of metal nanoparticles on the anaerobic digestion of sludge and the sludge bacterial community are still not well-understood, and both improvements and inhibitions have been reported. This study investigated the impact of 2, 10, and 30 mg/g TS silver and copper oxide nanoparticles (AgNPs and CuONPs) on the mesophilic anaerobic digestion of sludge and the bacterial community structure. The reactors were monitored for changes in tCOD, sCOD, TS, VS, biogas generation, and cell viability.[...]

Advances in Polyaniline-Based Composites for Room-Temperature Chemiresistor Gas Sensors
On 2025-02-03 by Clinton M. Masemola, Nosipho Moloto, Zikhona Tetana, Linda Z. Linganiso, Tshwafo E. Motaung, Ella C. Linganiso-Dziike @MDPI
Keywords: polyaniline, composites, chemiresistor, gas sensors, room-temperature
AI summary: Advances in using PANI-based composites for room-temperature gas sensors, Exploring the materials and mechanisms of PANI-based gas sensors, Highlighting the potential of PANI-based sensors for air quality monitoring, Instilling hope in safeguarding public health and the environment.
Abstract: The increasing rate of environmental pollution and the emergence of new infectious diseases have drawn much attention toward the area of gas sensors for air quality monitoring and early-stage disease diagnosis, respectively. Polyaniline (PANI) has become one of the extensively studied polymers in the area of chemical sensing due to its good conductivity and sensitivity at room temperature. The development of room-temperature gas sensors represents a significant leap forward in air quality monito[...]

Processing and Characterisation of Alumina/Eucryptite Nanostructured Composites
On 2025-02-03 by Inocente, da Costa, Mattos, Alcázar, Borrell, Moreno, Arcaro, Montedo @MDPI
Keywords: nanostructured composites, alumina, eucryptite, toughness, sintering
AI summary: Enhanced toughness achieved through nanostructured alumina/eucryptite composites. Complete crystallisation of eucryptite achieved at 850°C. Reduced sintering temperature improves fracture toughness. Economically viable and environmentally friendly production of lithium aluminosilicate nanoparticles.
Abstract: Alumina is one of the most studied and used ceramic materials, but increasing its fracture toughness is still a challenge for many specific impact applications. Adding a second phase with a low coefficient of thermal expansion (CTE) to an alumina matrix can enhance the matrix&rsquo;s mechanical properties, reduce its sintering temperature, and increase its toughness by generating compressive stresses on the alumina particle surface. In this study, nanostructured alumina/eucryptite compos[...]

AI summary: Comparative analysis of biosilica from rice husk and conventional silica, Evaluation of mechanical properties of silicone rubber filled with two types of silica nanoparticles, Biosilica shows comparable tensile strength to conventional silica at low filler contents, Potential utilization of rice husk-derived biosilica as an alternative to conventional silica
Abstract: The objective of this study is to compare rice husk-derived silica (biosilica) synthesized via an environmentally friendly method with conventional silica (Zeosil 175) for reinforcing the mechanical properties of silicone rubber. The silanol group content of Zeosil 175 (9.45 OH/nm2) is higher than that of biosilica (7.07 OH/nm2), whereas the specific surface area of biosilica (159.52 m2/g) exceeds that of Zeosil 175 (144.90 m2/g). Silicone rubber specimens containing two types of silica nanopart[...]

Abstract: Microwave-assisted synthesis presents a promising method for enhancing the formation of nanocomposites due to its rapid heating and uniform energy distribution. In this study, we successfully fabricated polyethersulfone&ndash;zinc-oxide (PES-ZnO) nanocomposite membranes by exposing PES/ZnCl2/DMF dope solutions to microwave radiation. Before synthesizing the membranes, zinc-oxide nanoparticles (ZnO-NPs) were optimized in an organic phase using microwave radiation to ensure effective nanop[...]
