Co-gasification of biomass and coal offers a strategic approach to enhance the sustainability of energy resources by exploiting the inherent synergies between various biomass components (cellulose, hemicellulose, and lignin) and coal. This study investigates the co-gasification in a downdraft fixed-bed reactor, focusing on the impacts on gas yield, calorific value, and carbon structure transformations. Thermogravimetric analysis revealed parameter-specific effects of biomass components during gasification. At a 50 wt% blending ratio, cellulose significantly enhances gasification, increasing calorific value and CO production beyond theoretical predictions. In contrast, lignin inclusion at a 70 wt% ratio decreases the calorific value and CO production by 6.44% and 11.21%, respectively. Additionally, hemicellulose is found to catalytically enhance CO 2 conversion, with a maximum increase of 45.99% at a 70 wt% ratio. The study elucidates the differential impacts of each biomass component on the co-gasification process and underscores the potential of optimizing biomass blends to maximize the efficiency and sustainability of energy production.

Solar-powered interfacial evaporators, though promising for seawater desalination and wastewater treatment, but suffer from the problems of monolithic structure and complex preparation. It is of great importance to develop a multi-layered solar evaporator that possesses stable and high-efficiency photothermal performance. Our research employs simple liquid-phase polymerization and chemical deposition methods to achieve this. The objective of this study is to develop a highly efficient solar evaporator, designated as SA/MWCNTs@PPy/MWCNTs-NH 2 @PU (SMPMPU), by integrating stearic acid (SA), multi-walled carbon nanotubes (MWCNTs), polypyrrole (PPy), and aminated multi-walled carbon nanotubes (MWCNTs-NH 2 ) within a polyurethane (PU) matrix. Inspired by typha orientalis, this evaporator boasts a highly antibacterial, self-floating Janus bilayer structure. This double-layered Janus solar evaporator utilizes the capillary adsorption effect to regulate the flow of water. It slows down heat transfer and significantly improves energy utilization efficiency. The resulting SMPMPU solar evaporator demonstrates a solar steam conversion efficiency with an evaporation rate of 2.40 kg·m −2 ·h −1 , which is attributed to the material's efficient absorption of light energy. Its evaporation efficiency under one sun illumination reaches 92.76 %, which can be credited to the Janus interface facilitating the absorption and evaporation of water molecules. The Janus bilayer structured solar evaporator developed in this study holds great promise and is anticipated to find widespread applications in seawater desalination and other related fields.

Hydrothermal carbonization has proven to be an effective method to convert sewage sludge into solid carbon-rich hydrochar , of which the high ash content is generally regarded as limiting factor for energy-related potential application. Hydrothermal co-carbonization of sewage sludge and high concentration phenolic wastewater was firstly investigated in this study as a scenario for production of clean solid biofuel with increased calorific value and decreased ash content, by means of polycondensation reactions between phenols and highly reactive intermediates of biopolymers in sewage sludge. Results showed that addition of phenolic wastewater into sewage sludge led to a substantial increase of hydrochar yield (1.83–31.11%) and higher heating value (1.01–10.01%) and a remarkable decrease of ash content (1.39–25.68%). The reaction temperature and residence time had a complicated impact on the contribution of phenol to hydrochar production. An increase in phenol mixing ratio was beneficial to the improvement of mass yield and higher heating value but showed a less influence on the reduction of ash content. The synergistic effects between phenols and sewage sludge on the production of solid biofuel were closely related to the phenolic species, which followed the order in the aspects of hydrochar yield increase and ash content decrease: phloroglucinol > p -nitrophenol > m -cresol > phenol. The changes of phenols content in liquid phase and variations of functional groups in hydrochars implied that phenols interacted with sewage sludge and incorporated into hydrochars during the hydrothermal co-carbonization. TG-DSC confirmed the improved combustion reactivity of the phenols-sludge-derived hydrochars.

Hygroscopic thermal fibers are a kind of functional material that makes use of moisture to generate heat for fabrics. In this work, composite fibers of polyacrylonitrile (PAN) and microcrystalline cellulose (MCC) with various compositions were prepared using a solution spinning method. Besides the promotion of mechanical properties of PAN by addition of cellulose reported in previous research, this study focused on the hygroscopic thermal property of blends and spun fibers of PAN and cellulose. The content of MCC in the composite fibers has a significant effect on the hygroscopic thermal property. At a temperature of 17 °C and humidity of 90%, the maximum temperature increase of composite fibers could reach 4.9 °C. The composite fibers exhibited an obvious temperature response of on–off humidity circulation during testing. The breaking strength of the composite fibers was higher than 100 MPa. The influence of addition of cellulose on morphology, especially on the crystallinity and lateral size of PAN microfibrils, and the relationship between the morphology and hygroscopic thermal property were investigated by means of wide-angle X-ray diffraction and small-angle X-ray scattering in terms of experiment and theory. A smaller lateral size of microfibril led to a better hydroscopic thermal property. The composite fibers were expected to be used in temperature regulation clothing. © 2022 Society of Industrial Chemistry.

Spontaneous thermal polymerization and carbonization assisted by calcium oxide was proposed for the first time to develop an incomparable synthetic route for the production of calcium-doped fluorescent carbon nanoparticles (FCNPs). This unique approach shares numerous virtues such as eco-friendly, moderate and controllable reaction, and uninvolved poisonous chemicals and intricate operations. Apart from several excellent photoluminescence properties of ordinary fluorescent nanomaterials, the FCNPs exhibited unexceptionable features in stark contrast to previous reports, especially possessing pH-sensitive fluorescence “off-on”, thermosensitivity, and superior optical performances under alkaline condition. Furthermore, the formation processes dramatically influencing the nucleation and growth of FCNPs were meticulously discussed according to the detailed material characterization. These investigations revealed the function of doping calcium and the fabrications of carbogenic cores coupled with oxygen-containing groups served as photoluminescence center and edge. It can be speculated that the synthesis of FCNPs will inaugurate new avenues for the design of multifunctional composites with other biomaterials and expand their applications in extreme alkaline conditions.

This study investigated the potential of eight types of green landscaping waste as feedstock to produce bio-oil through hydrothermal liquefaction (HTL). The eight selected plants differed in terms of botanical classification, morphology, leaf state, and growth habit. Leaves and branches as waste from these plants were separately subjected to HTL in a high-pressure batch reactor at 300 °C for 0.5 h. Results indicated the bio-oils and biochars of leaves obviously differed from those of branches in terms of yields and higher heating values (HHVs). However, less difference in yields and HHVs was found for HTL products within the eight leaves even though they were different in composition components such as cellulose, hemicelluloses, and lignin. The same was observed for branches. The average bio-oil yields of the leaves and branches were 33.74 and 43.22 wt%, respectively. The optimal bio-oil yield was 50.44 wt%, which was obtained when Cinnamomum camphora branches were used as feedstock. The average HHVs of light and heavy oils in the leaves were 25.13 and 31.27 MJ kg−1, respectively. These HHVs were higher than those of light and heavy oils in the branches (21.51 and 28.71 MJ kg−1, respectively). Among the oil products, the heavy oil derived from Salix alba leaves yielded the optimum HHV (35.63 MJ kg−1). The mean HHV of biochar was 24.17 MJ kg−1, which was considerably higher than that of feedstock (17.21 MJ kg−1). Gas chromatography-mass spectrometry and Fourier-transform infrared spectrometry revealed the presence of value-added chemicals, such as phenolics, ketones, esters, acids, and alcohols, in bio-oils. The amounts of alkanes, alkenes, and alkynes in the bio-oils derived from the leaves were higher than those in the bio-oils derived from the branches. These results indicated the feasibility of using different types of green landscaping waste as feedstock to produce bio-oils with high HHV and yield through HTL.

Metal fuels are widely used in energetic materials to improve their energy release. Al Si alloy fuel is an aluminum-based alloy fuel, and its slow reaction rate limits its potential application in energy material systems. Herein, Al-Si-Mg AlSi9Mgx alloy fuel had been designed and successfully prepared by gas atomization to achieve excellent reactivity characteristics. The reaction characteristics of the fuel were systematically measured by thermal analysis (TG-DSC), bomb calorimeter, volumetric explosion vessel system and laser ignition measurement. Due to the addition of highly active magnesium, the activation energy of alloy fuel was reduced, and the combustion efficiency was increased to more than 99 %, and the ignition delay time was reduced by 6.7 ms and 33.6 ms respectively. Combustion of potassium perchlorate (KP) mixtures shows that AlSi9Mgx alloy fuels had a faster flame propagation rate, 22.814 mm/s and 42.543 mm/s. The superior reaction properties of AlSi9Mgx alloy fuel are due to the presence of internal solid solution Mg or low melting point alloy compound. This work and design provide a reliable method for optimizing the energy output of alloy fuels.

The accurate measurement of the biomass lower-calorific-value-based blending ratio (BLBR) is the premise and key to scale development of the power generation technology from co-firing of biomass and coal. However, existing determination methods of BLBR are less accurate, which has impeded
the scale utilization of the co-firing technology of biomass and coal. To accurately determine the BLBR, this research proposed a flue gas sampling system suitable for determining BLBR through 14C quantitative analysis and established a medium-scale experimental platform for BLBR
determination. In addition, predictive models for the lower calorific values of coal and biomass fuels were built and the BLBR calculation model for co-firing power plants was deduced. Furthermore, experimental verification of the BLBR determination was also conducted. The results show that
the lower calorific values of coal and biomass fuels are highly linearly positively correlated with the carbon content. The relative errors of the established prediction models for lower calorific values of biomass and coal are separately lower than 5% and 8%. The results indicate that the
proposed BLBR determination method is accurate.

Introduction Severe fever with thrombocytopenia syndrome virus (SFTSV) is an emerging tick-borne bunyavirus that causes acute febrile illness with thrombocytopenia and a high mortality rate in humans. Currently, no specific antiviral agents have been approved for the prevention or treatment of SFTSV infection. The viral nucleoprotein (NP) is a critical component involved in viral RNA replication and transcription, representing a promising target for antiviral drug development. Methods We performed a structure-based virtual screening of the FDA-approved drug library using AutoDock Vina, aiming to identify potential inhibitors targeting the RNA-binding pocket of SFTSV NP. Promising candidates were further evaluated for antiviral activity in vitro. Results Among the screened compounds, lurasidone exhibited strong antiviral activity against SFTSV, with an IC 50 value of 4.552 μM and a selectivity index (SI) greater than 10, indicating favorable antiviral potency and low cytotoxicity. Mechanistic investigations suggest that lurasidone may exert its inhibitory effect by directly binding to the NP, thereby interfering with viral genome replication. Conclusion This study identifies lurasidone as a potential antiviral candidate targeting SFTSV NP and provides a theoretical basis for the repurposing of FDA-approved drugs against emerging viral infections. These findings offer new insights into therapeutic strategies for the treatment of SFTSV.

The inherent structural rigidity of lignin poses a significant challenge to its direct hydrogenation to produce aromatic compounds, requiring harsh reaction conditions. In this study, microwave-assisted hydrothermal liquefication was employed to rapidly generate raw bio-oil under mild conditions, coupled with an in-situ hydrogenation strategy to upgrade its quality. A series of lignin substrates were characterized to establish the relationship between lignin characteristics and aromatic products. Grass lignin can produce low molecular weight bio-oil in high yields (50.4–60.7 %) within 30 min at 180 °C, which is attributed to the abundance of cleavable β-O-4 linkages in its uniform structure. In contrast, softwood lignin with abundant guaiacyl (G) units possessed a robust thermal stability, resulting in a low monomer yield, but a high selectivity to G-type products (97 %). The raw bio-oil was further upgraded through in-situ hydrogenation with Pd catalysts. Low reaction temperatures (60–100 °C) favored the hydrogenation of aromatic aldehydes and ketones to their alcohol products, while high temperatures (100–220 °C) promoted the deep hydrogenation of aromatic side chains to alkyl products. Besides, an upgraded bio-oil with a higher heating value (29.8 MJ/kg) was obtained. Furthermore, the hydrogenation mechanism was investigated through the kinetics of simulated bio-oils. The activation energy follows the order: dimer β-O-4 linkage < monomer aldehyde group < ketone group < C C linkage, which is consistent with the hydrogenation kinetics observed in real lignin bio-oil. Overall, this study highlights the impact of lignin characteristics on subsequent conversion and also enhances our understanding of the complex depolymerization/hydrogenation mechanisms during lignin upgrading.

As humans and climate change continue to alter the landscape, novel disease risk scenarios have emerged. Sever fever with thrombocytopenia syndrome (SFTS), an emerging tick-borne infectious disease first discovered in rural areas of central China in 2009, is caused by a novel bunyavirus (SFTSV). The potential for SFTS to spread to other countries in combination with its high fatality rate, possible human-to-human transmission, and extensive prevalence among residents and domesticated animals in endemic regions make the disease a severe threat to public health. Because of the lack of preventive vaccines or useful antiviral drugs, diagnosis of SFTS is the key to prevention and control of the SFTSV infection. The development of serological detection methods will greatly improve our understanding of SFTSV ecology and host tropism. We describe a highly sensitive protein detection method based on gold nanoparticles (AuNPs) and enzyme-linked immunosorbent assay (ELISA)—AuNP-based ELISA. The optical sensitivity enhancement of this method is due to the high loading efficiency of AuNPs to McAb. This enhances the concentration of the HRP enzyme in each immune sandwich structure. The detection limit of this method to the nucleocapsid protein (NP) of SFTSV was 0.9 pg mL−1with good specificity and reproducibility. The sensitivity of AuNP-based ELISA was higher than that of traditional ELISA and was comparable to real-time quantitative polymerase chain reaction (qRT-PCR). The probes are stable for 120 days at 4 °C. This can be applied to diagnosis and hopefully can be developed into a commercial ELISA kit. The ultrasensitive detection of SFTSV will increase our understanding of the distribution and spread of SFTSV, thus helping to monitor the changes in tick-borne pathogen SFTSV risk in the environment.Keywords:SFTSV;nucleocapsid protein;gold nanoparticles;sandwich enzyme-linked immunosorbent assay

Co/CeO2 catalysts with different morphologies of polyhedrons (Co/CeO2–P), rods (Co/CeO2–R), sheets (Co/CeO2–S) and cubes (Co/CeO2–C) were prepared and compared on the catalytic upgrading of hydrothermal liquefied (HTL) biocrude derived from municipal sewage sludge (MSS) to biofuel. The best quality biofuel was achieved on Co/CeO2–C with a higher heating value (HHV) of 39.10 MJ/kg, where the sulfur and oxygen contents were reduced to 0.007 and 9.19 wt %, while the carbon and hydrogen contents were elevated to 77.5 and 10.1 wt %, respectively. In contrast, the pure ceria support presented a slight improvement for the upgrading of biocrude. Overall, this work provides a feasible solution for high-value utilization of MSS to produce high-grade biofuel.
