Summary: Research on biomass-based photothermal materials for solar steam power generation has been a recent hotspot, but there are still challenges to overcome. By co-hydrothermal carbonization of cotton stalks and MnO2, a new material (H-CS/MnO2) with super hydrophilicity and stable photothermal performance was prepared. Experimentally, H-CS/MnO2 showed a high evaporation efficiency of 93.46% and evaporation rate of 2.43 kg m(-2) h(-1) under 1 sun. Additionally, the material exhibited excellent salt and corrosion resistance, making it a promising option for practical applications in the future.

Summary: This study investigated the reusability and valorization of process wastewater generated during co-hydrothermal carbonization of organic fraction of municipal solid waste. The anaerobic digestion of process water and its recirculation up to five times enhanced the fuel properties of hydrochar, leading to increased energy yield, carbon content, calorific value, and overall combustion characteristics. The presence of high organic and ionic species in recirculated process water promoted the carbonization process and reduced the water related burden, creating a cleaner production system for renewable solid biofuels production.

Summary: Aqueous phase (AP) recirculation is a promising method to enhance biocrude production and alleviate the environmental impacts of AP discharges. Isothermal and fast hydrothermal liquefaction (HTL) experiments were conducted with different mixing ratios of water and AP products. The results showed that the optimum mixing ratio of 2:4 resulted in the highest biocrude yield. Nitrogen heterocycles and amides were found to be the major compounds in biocrude and AP, contributing to biocrude generation. AP recirculation for three times can significantly reduce wastewater discharges.

Summary: This study investigated the effect of PW recirculation on hydrochars at temperatures of 180, 220, and 260 degrees Celsius. The results showed that PW recirculation improved the mass yield and energy recovery efficiency (ERE) of hydrochars. With increasing temperature, the mass yield decreased while ERE initially increased and then decreased. PW recirculation promoted the increase of carbon content at 180 and 220 degrees Celsius. SEM analysis showed that PW recirculation promoted the formation of carbon microspheres, with fusion occurring at 260 degrees Celsius. Overall, PW recirculation could improve the hydrothermal carbonization process to some extent.

Summary: The lack of a quantitative understanding between the amount of under-coordinated sulfur (the most active ligands) and the Hg-0 removal performance of metal sulfide (MS)-based sorbents has impeded their rational design. This study introduces a novel method using tin sulfide (SnSx) nanosheets to independently adjust the abundance of under-coordinated sulfur in MS. A linear relationship is established, showing that a 1% increase in under-coordinated sulfur in SnSx enhances its Hg-0 capture capacity by approximately 0.9 mg g(-1). This quantitative relationship provides valuable guidance for improving the Hg-0 capture performance of MS-based sorbents.

Summary: This study conducted a direct observation of CO2 capture efficiency in the cultivation of microalgae Arthrospira platensis at high CO2 concentrations. The microalgae were grown in a 90 L photobioreactor using Zarrouk's medium. Three experiments were carried out with different initial CO2 concentrations: 1, 5, and 9 vol.%. The decrease in CO2 concentration due to microalgae growth was highest at 0.10 vol.% (CO2)/day in the experiment with an initial CO2 concentration of 5 vol.%. The biomass density growth rate was 79.4, 76.3, and 48.4 (mg/L)/day at 1, 5, and 9 vol.% CO2 concentrations, respectively. The viability of Arthrospira platensis was found to be good at 1% and 5% CO2 concentrations, but mass death of cells occurred at 9% CO2 concentration. Biochemical analysis showed a decrease in lipid and protein content with increasing CO2 concentration.

Summary: The large amounts of sewage sludge produced by municipal wastewater treatment plants pose significant environmental and economic challenges, necessitating advanced disposal methods. Conventional methods of sewage sludge disposal contribute to greenhouse gas emissions and pollution. Furthermore, sewage sludge-derived biochar often cannot be directly used in soil applications due to high levels of heavy metals and other toxic compounds, which affect soil biota and earthworms. In this review, we examine the co-pyrolysis of biomass and sewage sludge, focusing on the stabilization of heavy metals and reduction of toxicity in the sludge-derived biochar. We find that co-pyrolyzing sewage sludge with biomass materials reduces heavy metal concentrations and lowers the environmental risk of the resulting biochar by up to 93%. Biochar produced from co-pyrolysis can enhance the stimulation of soil biota reproduction by 20-98%. The immobilization and transformation of heavy metals are influenced by the mixing ratio of co-feed materials, pyrolysis temperature, and atmosphere.

Summary: The function of Exosomes from bone marrow-derived mesenchymal stem cells (BMSC-Exos) in corneal wound healing was explored, and the underlying mechanisms involving the p44/42 mitogen-activated protein kinase (MAPK) pathway were revealed. BMSC-Exos enhanced the proliferation and migration of human corneal epithelial cells (HCEs) in a dose-dependent manner. Activation of the p44/42 MAPK pathway mediated these effects of BMSC-Exos. In vivo, BMSC-Exos inhibited inflammation, fibrosis, and vascularization in corneal tissues, promoting corneal wound healing.

Summary: In this study, potent inhibitors for CDK2 were identified through a multistage virtual screening strategy and bioassay validations. Compound 1 (C1) showed better biochemical activity compared to other selected compounds, as validated by ADP-Glo Kinase assay. Cell viability assay demonstrated that C1 had a minimum inhibition concentration lower than 4 μM for CDK2. Further functional tests revealed significant antiproliferative, pro-apoptosis, and anti-migration activity of C1 in melanoma cell lines (A375 cells, WM35 cells, and A875 cells). The findings suggest that C1, screened from compound libraries, could be developed as an effective therapeutic agent for melanoma treatment.

Summary: This paper proposes a grey box model for fuel consumption prediction of wing-diesel hybrid vessels based on feature construction. By using both parallel and series grey box modeling methods and six machine learning algorithms, twelve combinations of prediction models are established. A feature construction method based on the aerodynamic performance of the wing and the energy relationship of the hybrid system is introduced. The best combination is obtained by considering the root mean square error, and it shows improved accuracy compared to the white box model. The proposed grey box model can accurately predict the daily fuel consumption of wing-diesel hybrid vessels, contributing to operational optimization and the greenization and decarbonization of the shipping industry.
