Abstract Lignocellulosic waste, consisting mainly of cellulose, hemicellulose and lignin, is the most abundant global biomass. Industries generate millions of tonnes of this waste biomass every year. This includes: sugarcane bagasse, corncob, rice straw and husk, oil palm fibres and empty fruit bunches, wheat straw, brewer’s spent grains, among others. These wastes could be valorized to produce high-value industrial lignocellulase enzymes, such as cellulases, hemicellulases and ligninases, by several microorganisms, including bacteria and fungi. Furthermore, the crude or purified lignocellulase enzymes or the microbes producing these enzymes could be used to hydrolyze the lignocellulosic wastes into… More >

Abstract Bio-derived carbon cryogels have garnered significant interest as promising electrode materials for supercapacitors due to their high specific surface area (SSA), hierarchical porosity, and eco-friendly synthesis methods. In this study, a tannin-modified phenolic hydrogel was synthesized using a sustainable tannin–phenol precursor system and subsequently subjected to three distinct drying methods-freeze-drying (FD), supercritical drying (SCD), and ambient pressure drying (APD)-to systematically evaluate their influence on structural integrity, porosity, and electrochemical behavior. Among these, the sample obtained via freeze-drying (TPUF-FD) maintained the most intact porous network, minimizing structural collapse during sublimation of ice under vacuum. This preservation… More > Graphic Abstract

Abstract Nickel (Ni) is an essential metallic micronutrient for optimal plant growth and development, regulator of essential metabolic processes, but its interaction with other essential nutrients can result in differences in the absorption of these nutrients, which can disrupt the ionic balance. The objective of this research was to evaluate the physiological performance and growth of soybean plants subjected to Ni levels applied via soil under Fe (iron) excess, determining the behavior of redox metabolism, gas exchange, and photosynthetic pigments. The experiment was conducted in a completely randomized design with a factorial 2 × 3, with… More >

Abstract Photoreforming is an emerging photocatalytic process that converts organic waste into hydrogen H₂ using solar energy, offering a dual solution for waste valorization and sustainable fuel production. This review comprehensively examines the fundamental mechanisms of photoreforming, emphasizing the critical role of photocatalyst design in optimizing hydrogen evolution. Key criteria for effective photocatalysts including suitable band edge positions, broad spectrum solar absorption, and photostability are systematically analyzed alongside advances in heterojunction engineering and defect modulation. The review further explores diverse waste-derived feedstocks, such as biomass: alcohols, saccharides, lignin and plastics: PET, PLA, polyolefins, highlighting substrate, specific challenges More > Graphic Abstract

Abstract The combined effects of macronutrients (Nitrogen, Phosphorus, and Potassium-N, P, K) and micronutrient fertilization on turmeric yield, soil enzymatic activity, microbial biomass, and nutrient dynamics remains poorly understood, despite their significance for sustainable soil fertility management and optimizing crop productivity across diverse agroecosystems. To investigate, a net house experiment on sandy loam Haplic Chernozem was conducted to 03 fertilizer regimes, viz. N₇₅P₅₀K₅₀ kg ha⁻¹ (T-2), N₁₂₅P₁₀₀K₁₀₀ kg ha⁻¹ (T-3), and N₁₀₀P₇₅K₇₅ + B₃Zn₆Fe₆ kg ha⁻¹ (T-4). Furthermore, the influence of these treatments was systematically assessed on soil nutrient status (N, P, K), enzymatic activities (alkaline phosphomonoesterase, dehydrogenase, fluorescein diacetate… More >

Abstract Biomass is a resource whose organic carbon is formed from atmospheric carbon dioxide. It has numerous characteristics such as low carbon emissions, renewability, and environmental friendliness. The efficient utilization of biomass plays a significant role in promoting the development of clean energy, alleviating environmental pressures, and achieving carbon neutrality goals. Among the numerous processing technologies of biomass, hydrothermal carbonization (HTC) is a promising thermochemical process that can decompose and convert biomass into hydrochar under relatively mild conditions of approximately 180°C–300°C, thereby enabling its efficient resource utilization. In addition, HTC can directly process feedstocks with high… More >

Abstract Essential oils (EOs) derived from medicinal plants are gaining recognition as sustainable alternatives to synthetic fungicides in the management of plant pathogens. This study investigates the chemical composition, chromatographic profile, and antifungal of Mentha rotundifolia essential oil against Fusarium oxysporum f. sp. albedinis (Foa), the pathogen responsible for Bayoud disease in date palm. The oil was extracted through hydrodistillation and characterized using thin-layer chromatography (TLC) and gas chromatography–mass spectrometry (GC-MS), revealing multiple fractions corresponding to terpenoid constituents and 23 chemical constituents, predominantly oxygenated monoterpenes (68.51%), with piperitenone oxide as the major component (62.53%). The antifungal efficacy was evaluated… More >

Abstract Selenium (Se) deficiency is a global health problem affecting more than 500 million people; crop biofortification is a sustainable strategy for its mitigation. This study investigated the effect of the application of selenate nanoparticles (SeO₄²⁻) and the combination of selenate (SeO₄²⁻) and chitosan (CS) (forming a SeO₄²⁻-CS complex) on the antioxidant profile, growth, biomass, bioactive compounds, enzymes, and Se accumulation of wheat (Triticum spp.) sprouts. Fourteen treatments were applied using a factorial design combining seven concentrations and two formulations: SeO₄²⁻ and SeO₄²⁻-CS. It was identified that chitosan increased Se uptake efficiency by 30% versus conventional selenate. The optimal… More >

Abstract Biomass-derived hard carbon has gradually become an important component of sodium-ion batteries’ anodes. In this work, Setaria viridis, a widely distributed plant, was employed as a precursor to synthesize hard carbon anodes for sodium-ion batteries. However, the hard carbon derived from raw precursors contains substantial impurities, which limit the performance of the obtained hard carbon. With different chemical etching processes, the content of impurities in the resultants was reduced to varying degrees. The optimized hard carbon anode delivered a reversible capacity of 198 mAh g⁻¹ at a current density of 0.04 A g⁻¹. This work shows the More > Graphic Abstract
