A novel thermally modified non-solvent induced phase separation (T-NIPS) fabrication method to produce translucent hollow fiber PVdF (THF-PVdF) photocatalytic membrane is developed. This method relies on attacking polymer crystalline property of PVdF by two steps temperature treatment process involving melting at high temperature (200°C) and rapid cooling at 0°C during spinning process thereby producing more γ-phase crystalline structure PVdF. The effect of membrane translucency on the photodegradation efficiency of immobilized photocatalyst were assessed. Graphitic carbon nitride in modified morphological structure (hollow nanofiber) were utilized. Membrane’s rejection, pure water flux and permeate flux of oil produced water were also investigated. The overall data shows that the produced membrane exhibits high translucency between 60.0% and 93.9% with THF-PVdF/PVP-GCN (2.0) exhibiting the highest. Comparatively, the filtration experiment on membrane with GCN photocatalyst showed high pure water flux (1200 L/m2h) and rejection (90%) of OPW than bare THF-PVdF and THF-PVdF/PVP. The photodegradation of GCN in suspended mode showed 99.98% degradation. The efficiency of GCN when immobilized in translucent membrane showed 95% photodegradation while membrane that is produced following commercial NIPS method showed only 49.40% photodegradation of OPW. This excellent performance is attributed by the transparency of membrane where the penetration of light is fully accommodated to the produced translucent photocatalytic membrane. The translucent photocatalytic membrane's preparation process and exceptional degradation efficiency meet the demands of current industrial productivity while also offering a bright application prospect for the industry. © 2023, The Authors.

The 2011 nuclear accident at Japan's Fukushima daiichi Nuclear Power Plant (FdNPP) prompted inquiries about the long-term transfer of Cesium-137 (137Cs) from soil to agricultural plants. In this context, numerical modeling is particularly useful for the long-term evaluation of the consequences of agroecosystem contamination. Agricultural practices, such as tillage and cover cropping, play key roles in 137Cs recycling in agroecosystems. In this study, we used 10-year monitoring data to develop a dynamic model to predict 137Cs redistribution (via uptake, litterfall, translocation, and percolation) under different tillage (no-tillage, NT;rotary cultivation, rC;moldboard plow, MP) and cover crop (rye;hairy vetch;fallow weed) treatments. The verification exercise and assessment results indicated the model's reliability, as the temporal dynamics of predicted values agreed with observed values. Tillage significantly influenced the 137Cs distribution in soil, thereby affecting plant uptake of 137Cs, whereas cover crop exerted a minimal effect on 137Cs cycling. Furthermore, while the 137Cs concentrations in soybean grain under rC and NT treatments were comparable 62 years after the FdNPP accident, the concentration under MP treatment remained consistently the lowest. despite natural decay being the main cause of the decreased global 137Cs level in the agroecosystem, with minimal losses from percolation to deeper soil layers and soybean harvesting, adopting an appropriate tillage practice was shown to promote a long-term reduction of 137Cs concentration in crops. Finally, to improve the model’s accuracy, further research should consider incorporating the effects of soil properties and extreme weather events on 137Cs flow into the model, as these factors are essential for realizing improved agroecosystem predictions. © 2023, The Authors.

BACKGrOUNd:Autologous bone remains the gold standard for surgical bone reconstruction but presents clinical challenges like donor site complications and operational difficulties. METHOd:We investigate the osteogenic effects of a newly designed, ceramic and collagen-based, submicron-processed Flexible Hydrated-Hardening Bone Graft (FHBG), using both murine and human mesenchymal stem cells. We also compare the efficacy and safety of FHBG with a commercially available (CA) graft in New Zealand white rabbits with cranial bone defects. rabbits were divided into three groups: no graft, CA, and FHBG, and evaluated using Micro-CT and histological analysis at three and six weeks post-surgery. Safety was assessed through blood samples. rESULTS:In vitro, FHBG promoted osteogenesis and upregulated osteogenic-associated genes in mesenchymal stem cells. In vivo, FHBG significantly enhanced bone regeneration, showing approximately 25% and 30% more improvement than the control at three and six weeks post-surgery. FHBG also had about half the residual content compared to the CA group. Blood analysis showed no hepatotoxicity or nephrotoxicity associated with the graft. CONCLUSION:FHBG significantly promotes bone regeneration both in vitro and in vivo. Additionally, FHBG has been demonstrated to be safe, with fewer residuals remaining in the body compared to currently in-use clinical bone grafts. This study validates the ability of the newly designed FHBG to facilitate osteogenesis in vitro and demonstrates its efficacy and safety in new bone formation in vivo. The lower residual material further suggests a reduced long-term impact and associated risk with the graft.

Artificial graphite (AG), in contrast to natural graphite, has received much attention due to its superior rate capabilities and stability under high current density. Although the rate capabilities can be enhanced by employing artificial graphite, there is room for improvement in the cycle retention characteristics of artificial graphite. In particular, further optimization on the binder type on anodes is necessary, as commercially used polyvinylidene fluoride (PVdF) has limitations in long-term cycling stability. Furthermore, PVdF is dissolved in N-Methyl-2-pyrrolidone (NMP), which is not environmentally- and eco-friendly. In this work, we have introduced a water-soluble binder based on deacetylated kondagogu gum (KG) for AG anodes, which are derived from the gum tree. Upon deacetylation, kondagogu gum can be dissolved in water, which can be directly used together with active materials and conductive agents in a slurry. replacing a PVdF binder with a KG binder results in an enhanced cycle retention and comparable rate capabilities, without the changes in the overall redox reactions with Li⁺. Postmortem analysis reveals that the improved electrochemical performance of the AG anode contributed to the excellent structural integrity of the KG binder compared with the PVdF binder. © 2023 The Author(s)

Biochar has high potential for long-term atmospheric carbon storage in terrestrial environments, contributing to meet UK and global greenhouse gas emission reduction targets. This study investigates greenhouse gas emissions and techno-economics associated with biochar produced from anaerobic digestate using hydrothermal carbonisation with post carbonisation at higher temperatures. While digestates are challenging to valorise, owing to high moisture contents, these low-value feedstocks have steady availability with minimal competition for other applications. The study scope includes food-waste digestate supply, stable biochar production, agricultural field application including co-benefits, and transportation activities. Minimising digestate transport through co-location of biochar production with anaerobic digestion demonstrated greenhouse gas mitigation costs of © 2023, The Authors. All rights reserved.

Applied Thermal Engineering 2025年 277卷

Investigating the boiling heat transfer mechanisms of non-azeotropic refrigerant-lubricant mixture on modified surfaces is crucial for optimizing the design of refrigeration and heat pump systems. In this study, the nucleate boiling heat transfer characteristics of r454B-POE and r32-POE mixtures on modified surfaces are measured with the oil concentrations of 1 wt%, 3 wt%, and 5 wt%. The modified surfaces include microcolumn surface (MS), femtosecond laser-processed micro-nano composite surface (FLMS), oxidation-etched micro-nano composite surface (OEMS), and micro-nano composite surface modified with low surface energy substance (MS-LSE). The results indicate that the influence of lubricant on the boiling heat transfer performance of r454B is relatively small compared to that of r32. On the MS-LSE, the presence of lubricant improves the performance of r454B at low heat flux below 170 kW/m 2 . However, on the other modified surfaces, the presence of lubricant negatively impacts heat transfer performance. The negative effect of lubricant on the heat transfer on OEMS is the largest. As the oil concentration increases, the negative impact of the lubricant becomes more pronounced. At a wall superheat of 10 K and an oil concentration of 1 wt%, the heat fluxes of the r32-POE and r454B-POE mixtures on the OEMS are 75 kW/m 2 and 114 kW/m 2 , respectively. In contrast, on the MS-LSE, the heat fluxes of r32-POE and r454B-POE mixtures are 155 kW/m 2 and 750 kW/m 2 , respectively. These findings provide a theoretical basis for optimizing heat exchanger design in refrigeration and heat pump systems.
