Crystalline red phosphorus (CRP), known for its promising photocatalytic properties, faces challenges in photocatalytic hydrogen evolution (PHE) due to undesired inherent charge deep trapping and recombination effects induced by defects. This study overcomes these limitations through an innovative strategy in integrating ruthenium single atoms (Ru 1 ) within CRP to simultaneously repair the intrinsic undesired vacancy defects and serve as the uniformly distributed anchoring sites for a controllable growth into ruthenium nanoparticles (Ru NP ). Hence, a highly functionalized CRP with Ru 1 and Ru NP (Ru 1-NP /CRP) with concerted effects in regulating electronic structures and promoting interfacial charge transfer has been achieved. Advanced characterizations unveil the pioneering dual role of pre-anchored Ru 1 (analogous to the “Tai Chi” principle) in transforming CRP photocatalysis. The regulations of vacancy defects on the surface of CRP minimize the detrimental deep charge trapping, resulting in the prolonged lifetime of active charges. With the well-distributed in situ growth of Ru NP on Ru 1 sites, the constructed robust “bridge” that connects CRP and Ru NP facilitates constructive interfacial charge transfer. Ultimately, the synergistic effect induced by the pre-anchored Ru 1 endows Ru 1-NP /CRP with an exceptional PHE rate of 3175 μmol h −1 g −1 , positioning it as one of the most efficient elemental-based photocatalysts available. This breakthrough underscores the crucial role of pre-anchoring metal single atoms at defect sites of catalysts in enhancing sustainable hydrogen production.

This study was conducted to find the possibility of replacing synthetic polymer polyvinyl alcohol (PVOH) with a natural polymer starch in manufacturing PVOH-coated paper for food packaging. Accordingly, different amounts of starches containing PVOH were coated on paper. Further, esterification was performed with palmitoyl chloride using the gas chromatography grafting technology. The grafting efficiency was evaluated using the Cobb size value and static contact angle of the PVOH-starch coated paper varying the addition amount of starch. The addition of starch resulted in an increased Cobb size value and a decreased static contact angle of the coated paper. These changes were proportional to the amount of starch mixed with PVOH, resulting from a reduction in the proportion of the hydroxyl groups available. Therefore, the grafted fatty acid content also decreased with the increasing amount of starch added. However, these results conclude that environment friendly starch can be substituted for PVOH in packaging substrate with hydrophobicity because no significant decrease in the hydrophobicity of the PVOH-starch coated paper was observed with less than 10% of starch. © 2019 Korean Technical Assoc. of the Pulp and Paper Industry.

Agricultural systems contribute significantly to environmental degradation and health impacts due to conventional practices such as postharvest open burning and the widespread use of chemical fertilizers. This study evaluates the potential for circular agricultural practices to mitigate these impacts in Thailand by repurposing agricultural residues for fertilizer, animal feed, and electricity. Utilizing a Life Cycle Assessment (LCA) methodology, the environmental and economic outcomes of conventional versus circular agricultural practices were quantified, focusing on key Area of Protection (AoP) including disability-adjusted life years (DALY), ecosystem damage (***), and resource depletion (USD 2013 ). The results demonstrate that conventional sugarcane and rice cultivation lead to substantial health impacts (up to 2910 DALY), significant ecosystem damage (up to 4.45 ***), and resource depletion costs of up to 14.9 million USD 2013 . In contrast, cassava cultivation, with its existing circular practices, shows comparatively lower impacts, including 415 DALY, 1.47 *** of ecosystem damage, and 10.4 million USD 2013 of resource depletion. Circular agricultural scenarios, using crop residues to produce organic fertilizers and animal feed, proved highly effective in reducing these burdens. Circular organic fertilizers reduced total costs by 57 %, while converting residues into animal feed resulted in a net economic benefit of 1.98 billion Thai Baht (THB), representing a 137 % reduction in costs compared to the baseline. The findings highlight the importance of transitioning to circular models, emphasizing the need for policy interventions, improved technology access, and enhanced farmer training to promote circular agricultural practices in Thailand.

The Cantang Grouper (Epinephelus fuscoguttatus-lanceoulatus) is a mating of the female Tiger Grouper fish (Epinephelus fuscoguttatus) and the male Kertang grouper fish (Epinephelus lanceoulatus). However, in farming activities, the Cantang Grouper fish can be affected by a VNN infection. One way to deal with the VNN infection is by giving recombinant nano-vaccine from the microalga Chlorella Vulgaris. This study aims to determine the effect of recombinant nano-vaccine administration of the microalgae Chlorella Vulgaris on the growth of the fish weight, length, and eye tissue in the Cantang grouper fish (Epinephelus fuscoguttatus lanceolatus) infected with Viral Nervous Necrosis (VNN). The method used in this study is experimental. The test results showed that the administration of the recombinant C. vulgaris (p-PerCv) vaccine affected the growth in length and weight of the Cantang grouper, this was because the growth in length and weight of its from the treatment group was significantly different from the control group (0.039<0.05). Known by the ANOVA test and also has a different effect on the level of damage to eye tissue both damage to hypertrophy, vacuolization, and necrosis. The results of the Tukey test showed that the treatment that had a significant effect was the T1 treatment (treatment of healthy fish +33l of recombinant C. vulgaris vaccine (p-PerCv) +8.5l of Chitosan nanoparticles).

One of the causes of increasing greenhouse gases is the increase in CO2 emissions produced from both the industrial sector, transportation sector, and settlement sector. The settlement sector also contributes to CO2 emissions based on household activities. Research on carbon footprint from settlement activities is currently focusing on carbon footprints from household energy use both electricity and heat energy for cooking and have not taken into account the activities of vehicle fuel use, domestic waste, and water consumption. This paper aims to conduct a literature study on matters relating to the method of estimating the carbon footprint of settlement activities and influencing variables. The results of this study are a framework for estimating the more comprehensive carbon footprint of housing activities by adding private vehicle fuel consumption, waste generation, and water consumption in addition to the use of fuel for cooking and electricity use. © The Authors, published by EDP sciences, 2019.

Sustainable Cities and Society 2025年 130卷

作者： Li Gong Xiang Zhang Zhou Guo Ryan Winston Shiyong Tao Joseph Smith State Key Laboratory of Water Resources Engineering and Management Wuhan University Wuhan 430072 China Hubei Key Laboratory of Water System Science for Sponge City Construction Wuhan University Wuhan 430072 China Department of Food Agricultural and Biological Engineering Ohio State University Columbus OH 43210 USA Department of Civil Environmental and Geodetic Engineering Ohio State University Columbus OH 43210 USA Environmental Science Graduate Program Ohio State University Columbus OH 43210 USA

Flood resilience assessment has become increasingly important for effective stormwater management in the context of frequent urban flooding disasters. Flooding in riverine cities is influenced by various factors, but resilience assessments usually only consider the impact of heavy rainfall. Given the lack of flood resilience assessment under compounding risks, this study proposes a resilience assessment method considering performance of different subsystems and constructs a framework composed of Copula analysis, scenario simulation, and resilience assessment. The joint probability distribution of rainfall and Yangtze River water level (YWL) was analyzed and a Storm Water Management Model was developed for hydrological simulation under composite scenarios in Dong-sha Lake Basin in Wuhan. The results revealed that the bivariate joint risk probability of rainfall and YWL was always higher than the exceedance probability of a single factor. The resilience of the pipe network was the highest among the three subsystems, whereas that of the lake system was the most variable. Besides, the hydrological simulation results showed that heavy rainfall is the main influence factor affecting flood resilience, while the higher the rainfall magnitude, the more important it is to consider the jacking effects of YWL. The proposed method evaluated the resilience-enhancing capacity of grey-green-blue infrastructures. This research proposes a resilience assessment method founded upon joint risk and provided valuable feedback for developing effective flood management strategies in riverine cities.
