Summary: In this study, we investigate the effect of electrochemical conditions (applied current density, electrolyte concentration) on the hydrogen loading (x) of an electrochemical palladium membrane reactor (ePMR). We find that x increases with increasing current density and electrolyte concentration, but reaches a plateau at x≈0.92 in 1.0M H2SO4 at -200 mA·cm-2. We also determine the influence of x on the thermodynamic driving force and demonstrate the ability of the ePMR to drive endergonic hydrogenation reactions.

Summary: This study investigated the low-temperature oxidation of n-heptane with and without the addition of NO. Experiments were conducted at atmospheric pressure over a temperature range of 500-800 K, and measurements were made using synchrotron vacuum ultraviolet photoionization mass spectrometry. The results revealed that NO addition exhibited an inhibiting effect below 650 K and a promoting effect above 650 K, with specific reactions responsible for these effects.

Summary: This study focuses on the development of an air-lift bio-electrochemical reactor (ALBER) with a continuous feeding regime to enhance nitrogen removal from synthetic wastewater. The effect of temperature, hydraulic retention time (HRT), N -NH+4 /TN ratio, and current density on the reactor performance was investigated, and the ALBER achieved a maximum TN removal of 73%. The results suggest that the ALBER has potential for treating industrial wastewater at low temperatures.

Summary: This study demonstrates a continuous electrochemical carbon-capture design using an oxygen/water redox couple and a modular solid-electrolyte reactor. By performing oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) redox electrolysis, the device can efficiently absorb dilute carbon dioxide (CO2) molecules and continuously output a high-purity CO2 stream. The system achieves high capture rates, high Faradaic efficiencies, high carbon-removal efficiency, and low energy consumption.

Summary: In this study, a custom-made electrochemical reactor was used to alkylate rice bran protein (RBP) and investigate its structure, morphology, and emulsification properties. The results showed that under a voltage of 35 V, the RBP exhibited changes in structure and properties, including increased beta-turn and random coil content, decreased alpha-helix and beta-sheet content, exposed CH3 groups, decreased S-S bonds, and increased free sulfhydryl (-SH) content. The modified RBP also showed improved emulsification properties with decreased particle size, increased zeta potential, enhanced contact angle, water holding capacity, fat holding capacity, solubility, emulsification capacity, and emulsification stability compared to the untreated RBP.

Summary: The use of lithium-ion batteries (LIB) in electric vehicles is growing rapidly, leading to an expected wave of spent LIB in the next 5 to 10 years. Various recycling technologies are under development to extract valuable metals from LIB, including hydrometallurgy, pyrometallurgy, and direct recycling. This study introduces an electrochemical membrane reactor for impurity removal in spent LIB, which consumes only air, water, and electricity to electroplate copper and precipitate aluminum and iron. The purified solution retains a high percentage of valuable metals and can be directly used for cathode precursor synthesis, while also generating a valuable by-product. This electrochemical process reduces costs and waste emissions compared to traditional methods.

Summary: This study developed a customized dual-chamber electrochemical reactor to recover phosphorus (P) from wastewater. The P removal efficiency of the dual-chamber reactor was 2.2 times higher than that of the single-chamber reactor. The purity of the generated vivianite reached 98.3% as confirmed by EDS analysis. High P concentration, moderate pH, and adequate current density were found to be conducive to vivianite production.

Summary: This study investigated the electrochemical oxidation (EO) technology as an alternative tertiary treatment in wastewater treatment plants (WWTP) to remove contaminants of emerging concern (CECs) and Escherichia coli simultaneously. The results showed that the removal rate of CECs depended on their structure and physicochemical characteristics, as well as the electrode material and shape used. MMO with a higher surface area and circular-mesh electrode exhibited the highest removal efficiency for recalcitrant CECs (20-50%). Varying the current intensity had a minor effect on CECs removal. The overall removal efficiency of CECs exceeded 90% within 2 hours, with simultaneous removal of E. coli. The EO process was considered ecofriendly with a low estimated treatment cost of 1.1 euro/m3.

Summary: A novel low-pressure sinterable Cu nanoparticle paste was developed by introducing Cu Metal Organic Decomposition (MOD) ink, which eliminated the surface oxidation of Cu nanoparticles and modified their structure. Strong Cu sinter joints were achieved at low pressure in a non-reductive nitrogen atmosphere, and the paste exhibited high shear strength at elevated temperatures, showing potential for industrial applications.

Summary: Complex metal hydrides have high hydrogen storage capacities but are limited by high temperatures for hydrogen release and slow kinetics for hydrogen uptake. This study investigates the vapor-phase delivery of chemical additives to modify Mg(BH4)2 materials, enabling low-temperature hydrogen release. The combination of characterization techniques, especially electron microscopy, provides insight into the mechanism and accelerates research in hydrogen storage materials.

Summary: A novel electrochemical active biofilms constructed wetland (NEAB-CW) was developed for the treatment of domestic sewage under low temperature conditions. The NEAB-CW system, which replaced traditional matrices with conductive layers, achieved higher removal efficiencies of COD, NH4+-N, and TP compared to traditional wetlands. The transverse and longitudinal electric potential variations in NEAB-CW improved microbial activities and electron transfer efficiency, resulting in higher and stable electric potential and electron current density. The NEAB-CW system accumulated pollutant-degrading, low temperature-resistant, and electrochemical active microorganisms, which contributed to electricity generation and pollutant degradation.
