Summary: Microbial fuel cell (MFC) is a promising alternative energy system that converts chemical energy into electricity with the help of microorganisms. It consists of electrodes (anode and cathode), catalyst (microorganism), and proton transport/exchange membrane (PEM). MFC's core function is the oxidation of organic substrates and electron transfer, with key factors being microorganisms and electrodes. Besides electricity generation, MFC also finds applications in wastewater treatment, biofuel production, and biosensors.

Summary: The electricity production through psychrophilic microbial fuel cell (PMFC) has been developed as an alternative solution for wastewater treatment in cold regions. This study successfully operated a two-chamber mixed-culture PMFC at 4 degrees C using acetate as an electron donor. The PMFC demonstrated good performance with high voltage, coulombic efficiency, and power density. The enriched biofilm showed direct electron transfer pathway, and the high psychrophilic activity of exoelectrogens genera contributed to the good performance of the PMFC. The mixed-culture PMFC provides a reasonable strategy to enrich exoelectrogens with high activity and has potential applications in energy generation and valuable chemical production in low-temperature regions.

Summary: This research investigated the co-cultivation of Chaetoceros calci-trans and Arthrospira platensis under outdoor conditions and evaluated pigment production using palm oil mill effluent (POME) as growth medium. Results showed that co-cultivation strategy produced abundant biomass at a salinity of 30 PSU, but the addition of POME reduced fucoxanthin production while maintaining C-phycocyanin (C-PC) production. Mixed culture using synthetic medium produced 27 mg/L C-PC and 5.4 mg/L fucoxanthin. The optimal conditions for co-cultivation were 33% POME, 100 mg/L urea, and 17 PSU salinity, resulting in 1.7 mg/L fucoxanthin and 25 mg/L C-PC production.

Summary: This qualitative study explored the experiences of non-native speaker postgraduate students in writing dissertations at a university in the UK. Interviews with international students from Indonesia, Malaysia, Thailand, and Japan revealed student-related challenges (technical writing, thinking in English, research topic identification, literature review, lack of communication skills, and boredom) and supervisor-related challenges. Participants used self-management strategies (reading, translation, key-point drafting, entertainment) and sought help from supervisors, proof-readers, and online services. The study suggests that postgraduate students should identify their own challenges as non-native English speakers and find effective strategies to overcome them.

Summary: Gasification kinetics of six chars from residual origin were studied under relatively low temperature, low CO2, and high H2O partial pressures. The Random Pore Model (RPM) showed the best fit to experimental results, but the selection of the reaction model depended on the ash composition, specifically the presence of alkali and alkaline earth metals. Chars with ash content higher than 30% wt. were modeled with the RPM model, while chars with the highest K/Si ratio required modified versions of the RPM to accurately predict reaction rates. Textural properties played a key role in determining reaction parameters, such as the pre-exponential factor and activation energy, for chars with similar ash content and composition.
