Summary: The effects of potassium carbonate (K2CO3) and potassium bicarbonate (KHCO3) on the hydration mechanisms of fluogypsum were investigated. Both K2CO3 and KHCO3 significantly increased the hydration rate, hydration heat release rate, and accelerated the hydration process of fluogypsum. The addition of these modifiers improved the solubility and compactness of the hardened fluogypsum, reduced the porosity, and changed the crystal morphology of dihydrate gypsum, leading to enhanced compressive strength.

Summary: This study describes a gas-free electrodialytic pH modifier for manipulating carbonate eluent in ion chromatography, achieving mixed eluents with different carbonate and bicarbonate ratios by controlling the migration of potassium ions and water splitting. The device can online convert at least 10 mM K2CO3 eluent into 10 mM KHCO3 with near-ideal Faradaic efficiency. Good reproducibility was demonstrated with RSD values for retention time and peak area below 0.43% and 0.93% respectively.

Summary: Cystic fibrosis (CF) is a disease characterized by abnormal transepithelial ion transport. This study proposes that biophysical abnormalities associated with CF mucus hyperconcentration provide a unifying mechanism. The findings from CF pig airway models and human airway studies suggest that elevated mucus concentration, osmotic pressures, and cohesive forces contribute to the accumulation of mucus in the airway surfaces and submucosal glands of CF lungs.

Summary: Cement production can be decarbonized by using electrochemical reactors to convert limestone into cement clinker precusor and release CO2 as a pure stream. A cement electrolyzer with a cell voltage of 1.8 V and 100 mA cm(-2) current density is reported, improving upon the previous record. Use of H-2 in the electrolyzer decreases the cost of cement production compared to using H-2 as a kiln fuel, as shown by a techno-economic model. This work advances the feasibility of electrochemical cement production.

Summary: Carbonate alkalinity plays a crucial role in regulating the pH and buffering capacity of natural water systems. This study proposes a novel TOC method to accurately measure carbonate alkalinity, which overcomes the limitations of conventional potentiometric titration methods. The TOC method provides rapid, automated, and reproducible measurements, even in the presence of high levels of dissolved organic matter or inorganic ions.

Summary: Anthropogenic pressures are restructuring coral reefs globally, and the excretion of intestinal carbonates by marine fishes plays a relevant role in inorganic carbon cycling. This study identifies body mass and relative intestinal length as the strongest predictors of carbonate excretion in reef fishes. The mineralogical composition of the excreted carbonates is highly conserved within families but also influenced by temperature and intestine length. These findings improve our understanding of the drivers and contributions of fishes to inorganic carbon cycling in coral reefs.

Summary: A phase change-based absorption process using potassium carbonate/bicarbonate solution is proposed for CO2 capture, aiming to reduce energy consumption to less than 1.5 GJ/(t.CO2). An energy-saving continuous reaction crystallizer is developed for collecting CO2-rich solid products. The effects of superficial gas velocity and fluid jet velocity on the performance of the reaction crystallizer are thoroughly investigated.

Summary: Acidic environments reduce the intracellular pH of most cells, but cancers maintain an alkaline cytoplasm. We identified AE2 as a regulator of resting pHi and found that cells adapt to chronic acidosis by degrading AE2 protein. Inhibition of lysosomal degradation of AE2 may be a potential therapeutic target for maintaining a conducive pH in tumors.

Summary: Plastic accumulation and degradation into microplastics is an environmental issue due to their widespread presence and release of intrinsic chemicals that can act as endocrine disruptors. Monitoring plastic additives in biological matrices, such as blood, can help understand the relationship between human exposure and health outcomes. This study analyzed the levels and frequencies of specific plasticizers in Sicilian women's blood of different ages, finding higher concentrations in younger females, possibly due to increased use of plastic products in daily life.

Summary: The study aimed to investigate the multistress effect of microplastic, salinomycin, and temperature on a bioindicator bivalve mollusk. The results showed that microplastic and salinomycin had limited effects on certain enzymes, but increased catalase, GST, and protein carbonyls. The findings highlight the importance of considering multistress interactions in the assessment of environmental risks posed by microplastics.

Summary: Although the toxic effects of antibiotics and heavy metals have been studied extensively, their combined adverse impact on aquatic organisms is not well understood. This study assessed the acute effects of a ciprofloxacin and lead mixture on zebrafish behavior, enzyme activity, oxidative stress markers, and essential elements content. The results showed that exposure to the mixture impaired zebrafish behavior, altered essential elements content, and increased oxidative stress. This highlights the potential threat to living organisms from the simultaneous presence of antibiotics and heavy metals in the environment.

Summary: Microplastics, measuring less than 5 mm in size, have become a significant environmental concern in marine ecosystems worldwide. They primarily originate from the breakdown of larger plastic debris and pose ecological risks to marine organisms when ingested. Approximately 80% of microplastics come from terrestrial sources, including skincare products, tire production, and improper plastic disposal near coastal areas.

Summary: Since the 2000s, the pearl oyster Pinctada imbricata has thrived in the transitional waterways of the Capo Peloro Lagoon natural reserve. This study investigates the immune-mediated responses of P. imbricata haemocytes to the aquatic pollutant Quaternium-15. Exposure to Quaternium-15 resulted in decreased cell viability, phagocytosis activity, and alterations in antioxidant responses. The findings suggest that P. imbricata could serve as a bioindicator for future toxicological studies.

Summary: The present study investigated the effect of Foeniculum vulgare essential oil on the health of common carp. It was found that an oral administration of 200 mg/kg of F. vulgare oil significantly improved the weight and growth rate of the fish, while higher doses of 600 mg/kg had negative effects on blood enzyme levels. Overall, adding an appropriate amount of F. vulgare oil can enhance the reproductive and general health of the fish.

Summary: This study investigated the effects of diazinon on fish and explored the potential protective effects of silymarin supplementation. Diazinon exposure caused liver damage in fish, but silymarin showed potential in reducing oxidative stress and restoring enzyme activities. However, the effectiveness of silymarin on creatine phosphokinase, glutathione reductase, and ammonia may be limited.

Summary: The aim of this study was to investigate the cytotoxic effects of the organophosphate insecticide chlorpyrifos on the mangrove crab. The results showed that chlorpyrifos caused cytopathological changes such as epithelial lifting, edema, necrosis, lamellae fusion, haemorrhage, haemocyte disappearance, muscle atrophy, and necrosis. Therefore, cytopathological observation is a promising biomarker for ecotoxicological studies.
