Summary: This work provides a critical review of recent studies on the use of heat-activated persulfate to degrade persistent micropollutants. The influence of various operating parameters, such as temperature and oxidant concentrations, is discussed, with higher temperatures and oxidant concentrations generally improving efficiency. The effect of the aqueous matrix is particularly emphasized, as studies have shown that the removal of pollutants decreases with increased complexity of the aqueous matrix, unless specific oxidative species are produced. The study also highlights the growing interest in combining different processes for persulfate activation and summarizes recent research on hybrid systems for micropollutant destruction.

Summary: Recent studies have found that microplastics are widely present in various environments. This study examined the sorption of two commonly used antihypertensive drugs onto polystyrene microplastics and investigated the effects of water matrix, pH, salinity, and aging on their sorption. The results indicate that the sorption of these drugs onto the microplastics is a slow process and is influenced by various factors. These findings suggest that microplastics could have potential adverse effects on the environment and public health.

Summary: This study examined the energy and environmental performance of photovoltaic (PV) panel cooling using phase change materials (PCMs). The energy analysis showed that although cooling increases the panel's energy output, PCM cooling requires a high initial energy investment, resulting in lower energy-return-on-investment values compared to PV. PCM cooling also increases PV's total environmental footprint. However, in the Greek context, the additional electricity attributed to PV cooling leads to significant environmental gains through fossil-fuel-dependent electricity substitution, while cooling can also prolong PV useful life and reduce temperature fluctuations and extremes on the panel's surface.

Summary: Pyrolysis of lemon stalks at 850 degrees C under limited oxygen produces highly active and selective biochar that can activate persulfate ion and oxidize sulfamethoxazole (SMX). The biochar consists mainly of carbon and oxygen atoms, with calcium and potassium as the most abundant minerals. It has a moderate specific surface area of 154 m(2) g(-1) and contains carbonate species, possibly in the form of calcium carbonate. In ultrapure water, complete degradation of 0.5 mg L-1 SMX can be achieved within 20 minutes using 500 mg L-1 sodium persulfate (SPS) and 100 mg L-1 biochar. The biochar remains stable for at least five cycles and shows potential as a sustainable, metal-free catalyst.

Summary: Coastal enhanced weathering (CEW) is a carbon dioxide removal approach that involves spreading crushed silicate minerals in coastal zones to be naturally weathered by waves and tidal currents, releasing alkalinity and removing atmospheric carbon dioxide. The use of olivine as a mineral candidate for CEW has been proposed due to its abundance and high carbon uptake potential. However, there are engineering challenges, such as particle size and transportation, as well as potential environmental stresses that may limit its applicability. The use of larger particle sizes could be a potential solution, but they dissolve much slower and require several years to become carbon and environmental net negative.

Summary: The pursuit of low-cost, high-efficiency co-catalysts without noble metals in photocatalysis has attracted significant interest in recent years. In this study, a series of cobalt phosphide (CoP 0.125-1.00 wt.%) promoted bismuth vanadate (BiVO4) photocatalysts were synthesized and characterized. The efficiency of these photocatalysts was investigated for sulfamethoxazole (SMX) degradation under simulated solar light irradiation. The results showed that the deposition of a small amount of CoP on BiVO4 enhanced SMX degradation.

Summary: This study examines the use of pristine Mo2C as a sodium persulfate (SPS) activator for the degradation of the drug losartan (LOS). The results show that acidic pH enhances LOS decomposition, and the apparent kinetic constant decreases with higher LOS concentrations. Sulfate radicals, hydroxyl radicals, and singlet oxygen are identified as the reactive species in LOS oxidation, with singlet oxygen being the predominant species. The addition of chloride accelerates the degradation rate, while bicarbonate and organic matter reduce the efficiency. The study also investigates the application of the Mo2C/SPS system for simultaneous LOS decomposition and elimination of Escherichia coli, with significant synergistic effects observed when simulated solar irradiation is present.

Summary: The paper proposes a novel deep learning-based prediction framework, aTCN-LSTM, for accurate cooling load predictions. The framework utilizes a gate-controlled multi-head temporal convolutional network and a sparse probabilistic self-attention mechanism with a bidirectional long short-term memory network to capture both temporal and long-term dependencies in the cooling load sequences. Experimental results demonstrate the effectiveness and superiority of the proposed method, which can serve as an effective guide for HVAC chiller scheduling and demand management initiatives.
