        <description><![CDATA[Coal liquefaction residue (CLR), a byproduct of coal-to-liquid technology known to adversely affect the ecological environment and human health, was investigated in this study for its influence on the rutting resistance of asphalt mixtures. The research employed the discrete element method in PFC2D to develop a rutting model, analyzing mixture behavior under varying temperatures and loads. CLR was used to replace fine aggregate volumetrically, with particular focus on particles ranging from 0 to 4.75 mm. Macroscopic rutting behavior was evaluated by examining fine particle displacement and force chain distribution. Results revealed that rutting development follows a power-function growth pattern, divided into three stages: 0–10 minutes, 10–20 minutes, and 20–60 minutes, with the initial 20 minutes being critical for rut formation. Particles exhibited strong self-organization adaptability, reducing stress concentration at rut initiation. During rutting evolution, particles sized 0.6–2.36 mm contributed significantly to deformation, while smaller particles (1.18–2.36 mm) were more prone to passive displacement due to compression and collision with larger particles (2.36–4.75 mm). In asphalt mortar with higher adhesive strength, however, the 0.6–1.18 mm particles were more extensively coated by larger ones, resulting in reduced displacement compared to the 1.18–2.36 mm fraction. The 2.36–4.75 mm particles served as a macroscopic skeleton, bearing and transmitting contact forces. Numerical simulations confirmed the rationality of replacing the 1.18–2.36 mm and 2.36–4.75 mm particles with indirect CLR of single particle sizes, and the 0.6–1.18 mm and 1.18–2.36 mm particles with direct CLR of single particle sizes. It was concluded that direct CLR significantly enhances the high-temperature performance of asphalt mixtures compared to indirect CLR, which aligns with macroscopic rutting test outcomes.]]></description>

        <description><![CDATA[As excellent peroxydisulfate (PDS) activators to degrade antibiotics, metallic nanoparticles (NPs) suffer from continuous ion leakage and declined efficiency. Herein, graphene coated nickel (Ni@G) NPs with 23.9–28.5 nm of Ni core and 7.9–2.1 layers of graphene shell were regulated via laser ablation in ammonia solution. Ni@G-loaded biochars (Ni@G/Bs) with developed porosity (23.8–145.7 m2/g) were prepared via crosslinking Ni@G with biochars derived from the pyrolysis of rice hull at 300 °C, 450 °C and 600 °C. By investigating the effects of catalyst species and dosage, PDS dosage, tetracycline concentration, circumstance temperature and coexisting anions, Ni@G/Bs presented k values of 0.0094–0.0301 min−1 for tetracycline degradation which were 47.0–81.5 fold enhancement than biochars. 7.26–3.61 μg/L of nickel ion leakage for 1st-5th cycles verified the excellent stability of Ni@G/Bs. Paracetamol (72.4%), ciprofloxacin (76.7%) and aureomycin (68.2%) could be degraded, showing a superior versatility of Ni@G/Bs. Free radical degradation pathway involving •OH, •SO4− and •O2− governed the degradation mechanism. While the non-free radical pathway mediated by 1O2 should not be ignored. This study paved a way for adjusting laser-ablated core/shell NPs and provided a new insight for integrating metal NPs and biochars to efficiently degrade antibiotics.]]></description>

        <description><![CDATA[The porosity parameter is one of the characteristic parameters of carbon aerogel, and the porosity and pore size distribution affect the infrared interference performance of carbon aerogel. In this study, nine types of carbon aerogel samples were selected to characterize and evaluate their micromorphology, particle size distribution, and porosity parameters. The objective was to obtain the characteristic parameters related to particle size distribution, porosity, and pore size distribution for these nine carbon aerogel samples. The infrared interference performance of nine types of carbon aerogel samples was evaluated in a smoke box. The analysis focused on the influence of porosity and pore size distribution on the interference performance across the infrared bands of 1–3 μm, 3–5 μm, and 8–14 μm. The results indicate that carbon aerogel exhibits a strong extinction effect across the three infrared bands. The increase in porosity leads to a higher infrared extinction coefficient, while an increase in average pore diameter can also enhance the infrared extinction coefficient.]]></description>

        <description><![CDATA[To overcome the dual bottlenecks of low intrinsic energy density in carbon materials and poor cycling stability of metal oxides, this study proposes a biomimetic hierarchical pore engineering strategy. Bamboo-derived biochar is transformed into a hierarchically porous architecture via synergistically coupled CO₂ physical activation (PHAC) and KOH chemical activation (CHAC), yielding ultra-micropores (0.55 nm, 42%) and mesopores (1.32 nm, 38%) with a micropore/mesopore volume ratio of 0.45. Ultrasonic-assisted impregnation enables uniform anchoring of 5 wt% MnCo₂O₄ spinel, forming strong interfacial C-O-Mn/Co bonds (12.4%) and mixed Mn³⁺/Mn²⁺ (62:38) that synergistically enhance charge transfer. The composite electrode achieves exceptional performance: 1258 F/g at 1 A/g, 80% capacity retention at 10 A/g, and 59.18 Wh/kg at 8.42 kW/kg. Critically, the dual activation eliminates negative pore volume artifacts and accelerates H⁺ transport in PEMFC hierarchical pores, establishing a new paradigm for hybrid energy storage.]]></description>

        <description><![CDATA[Electrosorptive removal of uranium from aqueous solutions has emerged as an auspicious approach for mitigating radioactive pollution, with carbon-based materials serving as pivotal electrode components due to their exceptional conductivity, tunable surface chemistry, and structural versatility. This review thoroughly examines recent progress in carbon-based capacitive deionization (CDI) electrodes for U(VI) removal and systematically assesses critical modification approaches, including heteroatom doping, surface functional group modification, and metal oxide loading. Each strategy is critically examined regarding its underlying mechanism, material design principles, and influence on uranium adsorption capacity and selectivity. A particular emphasis is placed on synergistic effects from combined modification approaches, which consistently outperform single-component systems. Bridging insights from environmental science and energy storage technologies, this work proposes an integrated optimization framework that establishes fundamental structure-performance relationships for CDI electrodes. By systematically synthesizing current research progress while identifying key knowledge gaps, this review offers strategic guidance for the rational design of next-generation carbon-based materials to enable efficient, selective, and sustainable radioactive wastewater remediation.]]></description>

        <description><![CDATA[IntroductionElectromagnetic wave absorption materials reduce incoming wave energy, with machine learning focusing on data-driven design methods. Traditional multi-objective regression methods often fail to provide accurate component predictions, limiting their performance.MethodWe propose a multi-objective predictive model for absorbent compositions. Using single-variable predictions as cumulative features in a regression chain improves feature representation. Performance metrics identify the optimal predictor variables for material composition, aiding in the classification of carbon nanotubes based on required performance and predicted values.Result and discussionExperimental results indicate that the model achieves better R2 and mean squared error for carbon nanotubes, carbon black, and carbon fiber than other methods, with optimal Accuracy and Matthews Correlation Coefficient in classifying carbon nanotubes, validating the method for material composition design.]]></description>

        <description><![CDATA[IntroductionMetal matrix composites reinforced with ceramic and carbon nanotubes (CNTs) are considered recently as new materials for thermal managements and heat sink applications of electronic components.MethodCu nanocomposites reinforced with CNTs and different content of Si3N4 up to 5 wt.% (CNTs-xSi3N4/Cu) are synthesized by electroless Cu deposition process. The produced (CNTs-xSi3N4/Cu) nanocomposites powder were divided into two groups of samples. The first group were consolidated by two steps of cold pressing at 600 MPa compaction pressure followed by sintered under Ar atmosphere at 850°C for 90 min. However, the second group of powders are spark plasma sintered (SPS) under vacuum by simultaneously applying compaction pressure of 50 MPa at sintering temperature of 850°C for one min. The microstructure and the chemical composition of the investigated CNTs and the produced CNTs-xSi3N4/Cu powders as well as the CNTs-xSi3N4/Cu sintered nanocomposites were investigated by FTIR, SEM, TEM, EDX, X-ray mapping and XRD. The sinterability of the produced CNTs-xSi3N4/Cu nanocomposites is evaluated by measuring the Archimedes’ density and the coefficient of thermal expansion (CTE).Results and discussionThe electroless coating process enhancing the homogeneous distribution of CNTs and Si3N4 reinforced particles in the Cu matrix by preventing the formation of the agglomerations and segregations in the Cu matrix and retaining the nanostructure. The density and the CTE of the obtained CNTs-xSi3N4/Cu nanocomposites were improved by consolidation with SPS. The CNTs-xSi3N4/Cu nanocomposites sintered by SPS process have higher relative density approaches 100 % and lower CTE of 1.8 × 10−5°C-1–1.6 × 10−5°C-1 than, the density of the CNTs-xSi3N4/Cu nanocomposites sintered by conventional powder metallurgy technique with relative sintered density approaches 85 % and CTE of 2.6 × 10−5°C-1–1.9 × 10−5°C-1. Our findings owing that; the produced CNTs-Si3N4/Cu nanocomposites are expected as suitable candidate materials for thermal managements and heat sink packaging materials of electronic components.]]></description>

        <description><![CDATA[IntroductionThe interaction between the materials themselves and cancer cells are rarely explored. Therefore, the biological roles of raw single wall carbon nanohorn (SWCNH) on endoplasmic reticulum (ER) stress in the apoptosis of CNE2 were explored.MethodsTherefore, ERS of CNE2 cells was induced by SWCNH, and 4-phenylbutyrate (4-PBA) was selected as a inhibitor of ERS. CNE2 cells were co-cultured with SWCNH, 4-PBA and SWCNH+4-PBA, respectively. Furthermore, the apoptotic status of CNE2 cells and its ROS (Reactive oxygen species) levels were determined. Moreover, the apoptotic protein expression of caspase 3 (cysteinyl aspartate specific proteinase 3), the expression levels of ER pathway protein eIF2α, ATF4 and CHOP, or the OS (Oxidative stress)-related proteins NQO1, GCLC, HO-1, and Nrf2 was detected, respectively.ResultsCNE2 apoptotic rate, ROS levels, the caspase 3 or ER pathway proteins ATF4 and CHOP expression, even the NQO1, GCLC, HO-1, and Nrf2 levels of oxidative stress-related proteins in the groups of SWCNH and SWCNH+4-PBA were higher compared to the control group. Moreover, these indicators were higher compared to the group of SWCNH+4-PBA (p < 0.05).DiscussionER stress is the key possible mechanism of CNE2 apoptosis induced by SWCNH. After injury of ERS, SWCNH causes oxidative stress injury, which may eventually lead to apoptosis of CNE2 cells.]]></description>

        <description><![CDATA[Quantum carbon dots (QCDs) were efficiently synthesized from post-extraction residues generated during nopal fabric production using a hydrothermal treatment. These QCDs were applied to nopal fabrics, enhancing their UV solar radiation absorption. The synthesized QCDs exhibited fluorescence emissions in the 200–300 nm range. An eco-friendly dispersion was created by incorporating QCDs into TiO2 for use in smart textiles, which underlines our commitment to maintaining a sustainable process. Bright and fluorescent patterns were successfully applied to commercial and nopal fabrics using a spray printing technique. Additionally, the QCDs demonstrated pH-sensitive color changes, paving the way for practical applications. This work represents an initial step towards a circular economy by utilizing residues from nopal fabric production to synthesize quantum dots, which may be employed in smart textiles applications with UV absorption capabilities.]]></description>

        <description><![CDATA[There has been a significant surge in the yearly use of plastics, leading to a notable rise in plastic waste generation. Consequently, the recycling of plastic garbage has emerged as a prominent concern around the world. This research explores the feasibility of using polyethylene furanoate (PEF) plastic waste as a substitute for coarse aggregate (CA) in concrete. Graphene nano-platelets (GNPs) were added to the concrete mix in different quantities to improve its structural reliability. The research study used an experimental research design in conducting its investigation. PEF waste plastic was added in concrete in varying proportions of 0%, 5%, 15%, 20%, and 25% as a supplementary material to gravel, and GNPs were added in different percentages of 0%, 0.03%, 0.05%, 0.08%, and 0.1% by weight of cement. Mechanical tests were conducted, which includes compressive strength (CS), split tensile strength (STS), flexural strength (FS), modulus of elasticity (MoE), and ultrasonic pulse velocity (UPV), and the environmental assessment of concrete was done by assessing carbon in concrete and concrete’s eco efficiency (ESE). It was found that 5% addition of PEF as the substitute to CA and 0.1% of GNPs gives the optimum strength, enhancing CS, STS, and FS by 9.10%, 18.18%, and 4.45%, respectively. Response surface technique (RSM) models were created to provide mathematical equations for predicting the predicted outcomes. All models were optimized using a multi-objective optimization approach and then validated.]]></description>

        <description><![CDATA[Wastewaters consist of organic pollutants that have environmental concerns. Wastewaters are treated by different methods, but efficient, low-cost, and sustainable techniques still need to be developed. Algae-based water pollution remediation techniques are considered to be sustainable approaches. This review exclusively discusses the facets of macro and microalgae in the treatment of organic toxicants. The current trends of algae-mediated water treatments have been discussed under adsorption and degradation methods. A focus on algae fuel cell, algae mediated activation of oxidizing agents, Fenton-like reactions, and photocatalysis was given. The need of algae-based adsorptive and catalytic materials was mentioned. The role of algae in the synthesis of catalysts which were employed in pollutant removal methods was also explained. The integrated algae-mediated water treatment techniques were also highlighted. The toxicant removal performances of different algae-based materials in the water medium were summarized. The conclusion and future prospects derived from the literature survey were described. This review will be helpful for researchers who are working in the field of sustainable water pollution remediation.]]></description>

        <description><![CDATA[Biodiesel is an eco-friendly, renewable alternative fuel, and it can be obtained from soybean oil, vegetable oils, animal fat, or microalgae. This study presents a comprehensive investigation into the production and characterization of microalgae biodiesel utilizing multiple analytical techniques, including CHNSO analysis, Fourier-transform infrared spectroscopy (FTIR), gas chromatography–mass spectrometry (GC–MS), and proton nuclear magnetic resonance spectroscopy (1H NMR). The CHNSO analysis revealed the elemental composition of biodiesel blends, highlighting the effects of TiO2 nanoparticle concentrations on carbon, nitrogen, sulfur, and oxygen content. With increasing TiO2 concentration, a steady increase in the carbon content and a gradual decrease in the nitrogen content were observed. According to the CHNSO analysis, the sulfur content of blended biodiesel was found to be lower than that of fossil diesel, with an empirical formula of CH2.26N0.000584S0.000993O0.0517. FTIR and 1H NMR spectroscopy confirmed the synthesis of biodiesel. Fourier-transform infrared resonance confirmed the presence of ester groups at 1732 cm-1, and a prominent peak at 1,455 cm-1 indicated a higher carbon content in the blended biodiesel. GC–MS analysis identified compounds of fatty acid methyl esters (FAMEs) and hydrocarbons. The major components of FAMEs were 9-octadecenoic acid methyl ester (C19H36O2), linoleic acid ethyl ester (C20H36O2), and hexadecanoic acid methyl ester (C17H34O2), with compositions 20.65%, 9.67%, and 6.26%, respectively. The presence of methyl ester in the blended fuel suggests its potential as an alternative fuel source.]]></description>

        <description><![CDATA[The significant increase in thermal efficiency and the rate of energy exchange used in fuel dynamics and automobile coolants are leading to a better understanding of nanofluids. This computational analysis explores the thermal conductivity performance for radiative cross-flow of a nanofluid across an expanding/constricting sheet with a suction effect as a result of its application. To compute or calculate the magnificent point of nanofluid flow, the entropy, and asymmetrical heat source/sink effects are also elicited. The boundary layers traverse a stream-wise procedure for expanding and contracting sheets. Additionally, the study examines the features of heat transfer and cross-flow of nanofluids using numerical simulations. By employing similarity variables, the basic PDE equations of the current model are transformed into ODEs, and they are subsequently evaluated using the bvp4c method. Therefore, the effects of embedded flow variables on drag force, heat transfer rate, and entropy generation profiles have been framed using parametric research. Multiple solutions are offered for a specific range of the contracting parameter as well as the mass suction parameter. In addition, the heat transfer rate accelerates due to the heat source and decelerates due to the heat sink. The literature that is already published has been compared favorably, and it reveals many commonalities.]]></description>

        <description><![CDATA[The escalating accumulation of toxic wastes and biowastes constitutes a critical environmental crisis that demands immediate and effective solutions. Traditional waste treatment methods, predominantly chemical and physical, are increasingly viewed as unsustainable, burdened by high operational costs and the risk of generating secondary pollutants. Against this backdrop, bioremediation emerges as a crucial and sustainable alternative, utilizing the natural detoxifying capabilities of microorganisms. This review article focuses on the use of fungal and bacterial strategies in bioremediation, emphasizing their vital role in the degradation, stabilization, or detoxification of pollutants. We provide an in-depth analysis of the mechanisms by which fungi and bacteria break down various contaminants, presenting a current snapshot of the field’s state of knowledge. The article highlights recent innovative advancements that improve the effectiveness and expand the applicability of bioremediation technologies. Moreover, it discusses the practical challenges of scaling these solutions to meet global environmental needs and suggests directions for future research and implementation. This synthesis not only underscores the significance of microbial bioremediation in addressing pressing environmental problems but also acts as a call to action for continued innovation in the sustainable management of hazardous wastes.]]></description>

        <description><![CDATA[The present article aims to examine the thermal performance and the sensitivity analysis of a GO−TiO2/water hybrid nanofluid in the presence of different nanoparticle shapes along with heat absorption and thermal radiation effects over a wedge geometry. Analyzing the effects of heat generation and radiation effects is one of the key studies conducted by researchers in various nanofluid flows over some required geometries. However, a combined study of these effects has yet to be studied over a moving wedge, and that combination defines the novelty of the work. Similarity transformations are implemented to the governing equations to obtain the final set of nondimensional equations, which are solved using the bvp4c code in MATLAB. The results obtained were in close agreement with the published results. The Nusselt number decreased with an increase in the heat source parameter Q, and it increased with an increasing Hartree pressure gradient β and thermal radiation parameter Rd. The sensitivity is statistically analyzed for the variations in radiation effect, heat source, and pressure gradient parameters on the Nusselt number. The high values for R2=99.99% and Adj R2=99.96% validate the ANOVA results obtained using a Box–Behnken design (BBD) model in the response surface methodology (RSM) with 14 degrees of freedom. The input parameters Rd and β show positive sensitivity, while Q shows negative sensitivity toward the skin friction. The Nusselt number proves to be most sensitive toward the pressure gradient parameter. TiO2, graphene (Gr), and the derivative forms of graphene, are gaining much importance due to their wide applications in the oil and petroleum industries. Thus, this study contributes to lubrication purposes, emulsion stabilizers, oxalic acid removal, anti-corrosive properties, etc.]]></description>
