In this investigation, calcium aluminate powders (CA) with various CaO/Al₂O₃ molar ratios were synthesized and the resulting calcined samples were employed as support for the preparation of nickel-based catalysts. The research indicated a significant impact of the calcium aluminate content on the physical and chemical structures as well as the catalytic efficiency of the samples. Among the evaluated samples, 12 wt%Ni/CA with a cement percentage of 30.55 % and a BET area of 8.56 m².g⁻¹ demonstrated superior catalytic activity, stability, and carbon deposition suppression in methane dry reforming. The results indicated that increasing the nickel loading from 6 to 15 wt% enhanced the conversion of CH₄ and CO₂. However, the maximum conversion values for CH₄ and CO₂ were achieved at 92.9 % and 98.4 %, respectively, at 800 ℃ over the sample containing 15 wt% Ni. Additionally, the selected catalyst, 12 wt%Ni/CA, was utilized in the direct reduced iron (DRI) process to assess its potential in DRI process.

This paper focuses on the potential of microbial fuel cells (MFCs) for electricity generation from wastewater and unused radio waves. MFCs use wastewater as a microbial activity to treat wastewater and produce electricity. On the other hand, unused radio waves are collected with the help of external circuits to harvest the energy and are later integrated into the MFC. This harvested energy can be used partly for the MFC chamber to reactivate inactive microbes and contributes to enhanced power production. The rest of the harvested energy can be stored in the MFCs. This method reduces pollution from radio waves and wastewater, turning them into energy and contributing to environmental sustainability. This is due to the global growth of wireless technologies like RF-based bandwidth devices like Wi-Fi, Bluetooth connections, and cell phone networks.

Due to their fast growth rates with high CO₂ fixation, efficient nutrient removal from wastewater such as palm oil mill effluent, and lower cultivation area needs compared to traditional energy crops, microalgae, known for their adaptability, present a viable renewable energy alternative. To maximize microalgae growth in a photobioreactor system and specifically target the capture of high CO₂ emissions from waste flue gases in the palm oil industry, this study focuses on evaluating Proportional-integral (PI) control strategies for such a purpose. The results show that algal productivity and CO₂ capture efficiency depend critically on flue gas flow rate, CO₂ inflow molar percentage, and higher dissolved oxygen (DO) levels. The hindering factors on algae growth are the elevated DO levels, highlighting the necessity of an efficient control strategy to reduce the generated DO in the medium. One such strategy's implementation resulted in up to 75 % CO₂ capture efficiency, or a 2 % CO₂ molar fraction in the headspace, along with significant algal growth and specific productivity, suggesting possible uses in the generation of biodiesel or biobutanol. The microalgae-specific productivity and the carbon capture efficiency were better balanced by including control techniques to lower DO levels.

The flotation results indicated that Cu²⁺, as the main component in the supernatant of bornite and malachite, significantly depressed the molybdenite in the sodium sulfide kerosene system, reducing its recovery from 84.87 % in deionized water to 60.44 % in the supernatant. The Zeta potential measurements and the Density Functional Theory (DFT) calculations confirmed that HS⁻ was chemisorbed on the molybdenite surface through the bridging effect of Cu²⁺, thus impairing the molybdenite flotation performance. The PHGMS experiments indicated that the recoveries of chalcopyrite, bornite, and malachite in the magnetic concentrate exceeded 90 %, while that of molybdenite was below 10 % at 0.8 T magnetic induction. The verification experiments showed that the recovery of pure molybdenite pre-treated by PHGMS was nearly 20 % higher than that of untreated samples in the supernatant.

The application prospects of CRMC in vertical barrier materials are explored in this study. The changes in flowability of Reactive Magnesia Cement (RMC) slurry and the unconfined compressive strengthen (UCS) and permeability characteristics of CRMC treated soils are investigated. The results show that the fluidity of RMC slurry decreases further with the increase of MgO substitute cement content.

The review evaluates key electrochemical techniques, including electrochemical leaching, electrodialysis, electrosorption, and electrodeposition, for their effectiveness in REEs recovery. Electrochemical leaching dissolves REEs from complex materials using fewer toxic chemicals. Electrodialysis, using an electric field, efficiently separates and purifies REEs from other ions. Electrosorption employs charged surfaces to selectively adsorb REEs with minimal energy, while electrodeposition directly recovers high-purity REEs from solutions. A life cycle analysis (LCA) comparing these techniques to traditional methods highlights their superior sustainability, especially in lowering energy use and greenhouse gas emissions.

The etching of nZVI with Na₂S effectively enhanced the catalytic conversion of TCE. The rough spherical morphology, intact core-shell structure, and amorphous sulfide species were all observed. The S-nZVI/PMS system facilitated a non-free radical pathway dominated by ¹O₂, driven by endogenous Cl^-, enabling the resource conversion of TCE into vinyl chloride (VC).
