Tuning the interaction between Cu and surface -OH in Cu/Ti3C2 MXene derived catalyst for enhanced semi-hydrogenation of dimethyl oxalate

Methyl glycolate (MG), a crucial chemical raw material and fine chemical intermediate, holds immense potential in the production of the next-generation biodegradable material, polyglycolic acid, via polycondensation reactions. In this study, layered Ti3C2 MXene was used as support precursor to construct Cu based catalysts for the semi-hydrogenation of dimethyl oxalate to MG. By fine-tuning the loading method of Cu species, the interaction between Cu species and surface hydroxyl groups (-OH) was modulated, and the effect on the semi-hydrogenation performance of Cu-based catalysts were thereby explored. These catalysts underwent rigorous characterization using BET, SEM-EDS, XRD, FT-IR, H2-TPR and XPS techniques. The results revealed that varying loading methods significantly influenced the interaction between Cu species and surface -OH on Ti3C2 MXene during preparation process, altering the content of Ti-O-Cu as well as the Cu0 ratio of Cu/Ti3C2-derived catalysts. The Cu/Ti3C2 MXene-I catalyst displayed remarkable performance, achieving a MG selectivity of 88.85 % and stability of up to 120 h in the DMO hydrogenation reaction due to its high Cu0 ratio and large Cu particles.

Industrial production of asymmetric wettability patterned fabric for efficient atmospheric water harvesting

While harvesting water from the atmosphere is considered as a promising technology to address the increasing issue of water scarcity, its wide applications are still limited by the difficulty in mass production of water harvesting materials. Here, an industrial-producible asymmetric wettability patterned fabric (AWPF) with high water harvesting capacity is developed using a continuous and low-cost weaving technology. Four textile patterns are developed for high-efficiency atmospheric water harvesting. The alternating patterned surface in AWPF is constructed with hydrophilic bumps and hydrophobic grooves using one set of green fluorine-free superhydrophobic polyester warp yarns and two sets of superhydrophobic polyester/hydrophilic viscose weft yarns. We optimized the water collection performance of the single-sided AWPF by spraying co-MBAA-DVB superhydrophobic material on the back of the AWPF to construct a wetting gradient, that is, double-sided AWPF. The double-sided AWPF shows a strong water harvesting capacity of 2840.2 mg·6h−1·cm−2, which increased the water harvesting efficiency by 43.2 % compared with the unoptimized single-sided AWPF. To reduce the pressure drop, 6 mm wide the double-sided AWPF was designed, resulting in a water harvesting capacity that is 1.23 times higher than that of without cutting. This advanced industrialized weaving technology with an asymmetric fabric structure design holds great potential for substantial water harvesting.

Deactivated Ca-based sorbent derived from calcium looping CO2 capture as a partial substitute for cement to obtain low-carbon cementitious building materials

Calcium looping CO2 capture is a highly promising technology for carbon capture, utilization, and storage. Nevertheless, the disposal of deactivated calcium-based sorbents following cyclic carbonation and calcination processes presents an unresolved challenge. Concurrently, the development of low-carbon cement products is also a critical priority. Given the calcium-rich composition and carbon-negative nature of the calcium-based sorbent, it is proposed that the deactivated sorbent could be utilized as a partial substitute for cement in the production of building materials. This paper explored the potential of using two types of deactivated calcium sorbent (DPC/DGC) to partial substitute cement for low-carbon cementitious materials production. The effects of partial substitution of cement materials on volume stability, compressive/flexural strength, hydration kinetics, and carbon emission of the composite cementitious materials were investigated. The results indicate that a 5% and 10% replacement of cement with DPC/DGC has modest impact on volumetric stability and compressive strength. The composite cement with 5% DPC replacement achieves a 28-day compressive strength of 48.1MPa, representing a 0.4% increase compared to the 47.9MPa observed in the reference sample. Specimens with 15% DPC/DGC substitution exhibit inferior volume stability and mechanical performance than the control sample. The total hydration heat releases decrease with the increasing substitution ratio due to the dilution effect by the introduction of DPC/DGC. Additionally, substituting cement with Ca-based sorbents significantly reduced the carbon footprint of construction materials. The net carbon footprints for the building materials that containing 1 ton of binder (substitued with 10wt% DPC and DGC) were 152.5kg and 43.5kg, corresponding to reductions of 79.6% and 94.2% compared to reference cement mortar. These carbon footprints are projected to further decrease to -108.5kg and -375.5kg when DPC and DGC were obtained after 100 CO2 capture cycles. A novel technological route combining the high-temperature calcium looping CO2 capture and CO2 mineralization curing was proposed, and the associated challenges of this method were also discussed.

Spatial confinement of MoS2 nanoparticles in jellyfish-inspired open-mouthed spheres for high-capacity and ultrafast-rate sodium-ion capture

Rational nanoscale structure engineering of electroactive nanoarchitecture is a very promising strategy for designing advanced capacitive deionization (CDI) materials. Herein, inspired by jellyfish physiological structure, open-mouthed MoS2/C hierarchical porous spheres were fabricated via direct-spray pyrolysis by adopting a strategy of coupling defective MoS2 with locally conductive network graphene quantum dots. Such a well-developed open-mouthed interconnected porous structure significantly stimulated the permeation of electrolyte ion the deep internal spaces of electrode, facilitated fast ion diffusion and provided abundant electrochemical adsorption sites, endowing the MoS2/C electrode with a remarkable desalination capacity of 118.83 mg g−1, an impressively rapid desalination rate of 51.35 mg g−1 min−1, and a good long-term cycle stability of 82 % after 50 cycles. This work inspires the design hierarchically porous composite materials with unique micro-nanostructures, offering a new viable route for the continuous and efficient production of CDI electrode materials.

Synthesis and Characterisation of Porous Carbide-derived Carbon from SiC in Molten Salt

Aims: In this paper, we aimed to prepare SiC-CDC with porous structure from SiC precursor by using simple molten salt electrochemical etching method at 900 ºC in argon at an applied constant voltage of 3.0 V. Background: Nanoporous materials include carbon materials, silica or alumina, gel, and zeolite, which have been known since ancient times. Among all these materials, carbon materials are particularly outstanding. In recent years, carbide-derived carbon (CDC), a type of unconventional carbon material produced by selectively extracting metal elements from the lattice of carbides, has attracted increasing attention from researchers. Many different methods have now been proposed to prepare CDC, among these methods, currently the preparation of mesoporous carbide-derived carbon (CDCs) materials mainly relies on chlorination. The main problems with chlorination are the corrosion of chlorine gas and the treatment of secondary products (MClx). Therefore, the search for environmentally friendly strategies for the production of CDC is still ongoing. Objective: This article proves that we can successfully prepare SiC-CDC with porous structure from SiC precursor by using simple molten salt electrochemical etching method at 900ºC in argon at an applied constant voltage of 3.0 V. Methods: The SiC-CDC with porous structure has been prepared from SiC precursor by using simple molten salt electrochemical etching method at 900ºC in argon at an applied constant voltage of 3.0 V. Results: The results show that the nanoporous SiC-CDC was successfully synthesized from the silicon carbide microspheres powder via by electrolysis in molten CaCl2 at 3.0 V, 900°C for 15 h. Conclusions: The nanoporous SiC-CDC was successfully synthesized from the silicon carbide microspheres powder via by electrolysis in molten CaCl2 at 3.0 V, 900°C for 15 h and their microstructure, specifc surface area, and pore size were analyzed. The SiCCDC obtained in this experiment mainly consisted of amorphous carbon and maintained the shape of SiC particles. The SiC-CDC is a mixture of amorphous carbon and ordered graphite phase with a highly degree of graphitization. The SiC-CDC displays a BET specific surface area of 561.39 m2/g and a total pore volume of 0.39 cm3/g. This method to produce SiC-CDC is very attractive because it will not only pave a new way for the preparation of SiC-CDC but also for mass production of high-quality carbon material.

Complex waste stream valorization through combined enzymatic hydrolysis and catabolic assimilation by Pseudomonas putida

Biogenic waste-derived feedstocks for production of fuels, chemicals, and materials offer great potential supporting the transition to net-zero and greater circularity. However, such feedstocks are heterogeneous and subject to geographical and seasonal variability. Here, we show that, through careful strain selection and metabolic engineering, Pseudomonas putida can be used for efficient co-utilization of highly heterogeneous substrate compositions derived from hydrolyzed mixed municipal-like waste fractions (food, plastic, organic, paper, cardboard, and textiles) for growth and synthesis of exemplar bioproducts. Experiments were designed to explore the combinatorial space of nine waste-derived monomers, displaying robust catabolic efficiency regardless of substrate composition. Prospective life-cycle assessment (LCA) and life-cycle costing (LCC) illustrated the climate change (CC) and economic advantages of biomanufacturing compared with conventional waste treatment options, demonstrating a 41–62% potential reduction in CC impact. This work demonstrates the potential for expanding treatment strategies for mixed waste to include engineered microbes.

Femtosecond laser-induced plasma-assisted backward deposition of robustly adherent porous carbon films on glass substrates

The simple and rapid production and transfer of high-quality carbon materials are crucial for the flexible and efficient fabrication of carbon-based electronic devices. Recently, a laser-assisted transfer method combining laser-induced carbonization and transfer printing was demonstrated for the one-step preparation and transfer of patterned laser-induced carbon films to transparent substrates. However, this method is limited by insufficient robustness and weak adhesion of the carbon film post-transfer. Herein, we developed a non-contact laser-induced plasma-assisted deposition method to deposit robustly adherent porous carbon films on glass substrates. By well-adjusting the laser parameters and inserting spacers with adjustable thickness, laser-induced plasma ablation replaced direct laser ablation during femtosecond laser scanning of the substrate-polyimide-carrier sandwich structure, resulting in micro-channels with a carbon-glass recast layer instead of easily peelable flakes on the glass substrate. This hierarchical structure significantly enhances the adhesion between the laser-induced carbon film and the glass substrate, ensuring outstanding stability of the deposited carbon film under various adhesion tests. Furthermore, compared to carbon films prepared by the laser-assisted transfer method, the obtained carbon films are hydrophilic, low-resistance, and porous, facilitating the fabrication of energy storage devices. To demonstrate its practical application, a planar carbon-based micro-supercapacitor was fabricated on glass, exhibiting excellent electrochemical and cycling performance.

Enhanced conversion of rosin to polymerized rosin with reusable Brønsted acid deep eutectic solvent

With the depletion of non-renewable resources and the increasingly serious environmental problems, the production of high value-added polymer materials using renewable resources as raw materials had aroused great interest. Deep eutectic solvent (DES)-[ChCl][TfOH]2 (prepared by choline chloride (ChCl) and trifluoromethanesulfonic acid (TfOH)), with suitable acid strength (H0=0.98) and active hydrogen, had been successfully used for enhanced conversion of rosin to polymerized rosin efficiently, under the conditions of rosin =15 g, mDES: mrosin=30 %, T=110℃ and t=9 h, polymerized rosin with high softening point (150.40℃) and low acid value (124.21 mg KOH/g) could be produced efficiently. [ChCl][TfOH]2 required no special treatment then could be reused for 5 times without significant loss of catalytic performance, on this basis, the green synthesis technology of polymerized rosin under DES system was given, not only promoted the further application of polymerized rosin, but also realized the high value-added utilization of renewable resource rosin. In addition, the formation mechanism of DES was systematically explained through DFT calculation, the reaction mechanism of rosin polymerization over [ChCl][TfOH]2 was explored, which could provide theoretical basis for further research.

Closing the Loop on Polyester: A Green Approach to Chemical Recycling with Zn[L-Proline]2 Supported Kaolin Catalyst

In present work, the depolymerization process utilizes kaolin-supported Zn[L-proline]2 (ZnP@K) as a recyclable Lewis acid catalyst, paving the way for the cost-effective production of recycled materials. The supported catalyst is characterized using FTIR, X-ray diffraction, SEM and BET analysis. The depolymerization of polyester textile waste, especially coloured threads, promoted by ZnP@K to yield more than 90% of monomers in pure form. In addition, irrespective of the colour of polyester threads, the process exhibited 100% conversion of polyester threads and obtained pure colourless monomers, bis(2-hydroxyethyl)terephthalate (BHET) and bis(2-hydroxyethyl)-terephthalamide (BHETA). The monomers are assessed for their structure and purity using FTIR, mass and NMR spectral techniques. While comparing with ZnO nanoparticles, ZnP@K depolymerized the polyester wastes in terms of yield and purity and it proved efficient and sustainable for recycling textile polyester waste.

Medicinal potential of adventitious root cultures of Hypericum perforatum: study on antioxidant stress and anti-melanogenic properties.

Adventitious root (AR) culture is an effective method for the production of Hypericum perforatum raw materials. However, the ARs are seldom utilized in practical applications. Therefore, this study investigated the effects of H. perforatum ARs on antioxidative stress and anti-melanogenesis, aiming for future applications in the development of related products. In the antioxidative stress experiment, tert-butyl hydroperoxide-stimulated HepG2 cells were pre-treated with 12.5-50 μg mL-1 of AR ethanolic extract (HpE), which significantly increased (P < 0.05) cell viability and reduced reactive oxygen species levels. In alcohol-stimulated mice, pre-treatment with HpE (2.5-10 mg kg-1) enhanced the activities of superoxide dismutase, catalase, glutathione, ethanol dehydrogenase, and acetaldehyde dehydrogenase, while reducing the levels of alanine aminotransferase, aspartate aminotransferase, and triglycerides. In the anti-melanogenesis experiment, α-melanocyte-stimulating hormone-stimulated B16-F10 mouse melanoma cells were pre-treated with 25-100 μg mL-1 of HpE, resulting in increased tyrosinase activity and melanin content, along with a decrease in the expression levels of microphthalmia-associated transcription factor, tyrosinase-related proteins, and tyrosinase. HpE efficiently protects HepG2 cells from oxidative stress and safeguards the liver in mice by mitigating oxidative damage. Additionally, HpE inhibits melanin synthesis in B16-F10 cells by suppressing tyrosinase activity. These findings suggest that H. perforatum ARs hold potential for use in the development of healthy foods, cosmetics, and pharmaceutical products aimed at antioxidative stress and anti-melanogenesis. © 2024 Society of Chemical Industry.

Electrochemical exfoliation of graphite using aqueous ammonium hydrogen carbonate solution and the ability of the exfoliated product as a hydrogen production electrocatalyst support

Electrochemical exfoliation of graphite has attracted much attention as a practical mass production of two-dimensional graphene-like materials. There is an increasing desire to find new and improved methods to create unique exfoliated products with excellent functionality. We used aqueous ammonium hydrogen carbonate solution as a new electrolyte for anodic oxidative exfoliation of graphite. The exfoliated product has a porous two-dimensional structure, and it can be dispersed in water for over five years. The oxidized and defected porous surface serves as an ideal support for molecular metal complexes, effectively functioning as heterogeneous electrocatalysts for hydrogen production.

Utilizing the mutant library to investigate the functional characterization of GhGLR3.4 regulating jasmonic acid to defense pest infestation.

The glutamate receptor (GLR) serves as a ligand-gated ion channel that plays a vital role in plant growth, development, and stress response. Nevertheless, research on GLRs in cotton is still very limited. The present study conducted a comprehensive analysis of GLRs gene family in cotton. In total, 41 members of the GLR family were identified in cotton unveiling distinct subgroups in comparison to Arabidopsis. Among these members, the third subgroup highlights its pivotal role in cotton's defense against insect infestation. Furthermore, the CRISPR/Cas9 system was utilized to create a mutant library of GLR members, which consisted of a total of 135 independent mutant lines, resulting in the production of novel cotton materials with valuable breeding potential for pest control. Further, this study elucidates the influence of GhGLR3.4 on jasmonic acid (JA) pathway signal transduction and demonstrated its participation in the influx of intracellular Ca2+, which regulates "calcium transients" following stimulation, thereby influencing multiple intracellular reactions. The study also found that GhGLR3.4 influences the synthesis of the JA pathway and actively partakes in long-distance signal transmission among plants, facilitating the transfer of defense signals to neighbor leaves and thereby triggering systemic defense. Consequently, this research advances our knowledge of plants' comprehensive defense mechanism against insect pest infestation.

Sustainable building solutions: A comprehensive study on PCPET waste-induced bricks

An exponential increase in plastic production and a substantial rise in plastic waste have forced scholars to seek a sustainable and groundbreaking solution that recycles/reuses plastic waste to minimize its adverse environmental impacts upon disposal. Having been used by various sectors, production of construction material from plastic waste has received more interest. Numerous studies have proven that shredded polyethylene terephthalate (PET) plastic bottles constitute a valuable construction material where plastic waste management/recycling procedures are not effective. The goal of this study lies in factors such as strengthening construction material, reducing carbon emissions in atmosphere and minimizing overall costs. Manufacturing plastic M-sand bricks, and integrating post-consumer PET (PCPET) from single-use plastic water bottles into M-Sand is the main focus of our research. This work used two types of PCPET wastes (washed and unwashed) with different mix proportions of plastic and M-sand, such as 1:1, 1:2 and 2:1 for brick production. The bricks manufactured are tested for durability through compression, water absorption, efflorescence, and dimensional stability, and subsequently, Energy Dispersive X-ray Analysis (EDX) and scanning electron microscopy (SEM) for morphological assessment. By the conducted experiential results, it is evident that the design mixes M3 and M8 guarantee appreciable strength that is 2–1.5 times of other mix designs. The M3 design mix with one part washed PCPET and two parts M-sand has exhibited superior performance, with a compressive strength of 40.29 N/mm², minimal water absorption, and observed homogeneity in SEM. In addition, post-demolition sustainability is addressed by integrating recycled brick aggregate with M-sand, showing optimal results for design mix M8, including a compressive strength of 40.54 N/mm², favorable water absorption, and positive SEM findings. EDX confirmed zero carbon elements in the produced bricks. These findings prove the strength of our research on the sustainable recycling of waste thermoplastics within the circular economy, presenting a promising solution to environmental and economic challenges.

Optimal operation guidelines for direct recovery of high-purity precursor from spent lithium-ion batteries: hybrid operation model of population balance equation and data-driven classifier

The direct resynthesis of precursor from spent lithium-ion batteries (LIBs) via co-precipitation is a crucial step in closed-loop cathode recycling systems. However, design and operation strategies for producing high-purity precursors have not been comprehensively explored or optimized. Herein, we propose the optimization of co-precipitation during the recovery of spent LIBs to achieve impurity-free precursor resynthesis. By incorporating the thermodynamic equilibrium model of the leaching solution of spent LIBs into a population balance equation (PBE) model, we identified the operating ranges that prevented the formation of impurities. Bayesian optimization was employed within the screened operating ranges to determine the optimal operating conditions for minimizing both operation time and maximum particle size. This optimization was performed for both unseeded batch and semi-batch systems. The results demonstrate that the selection of an optimal semi-batch operation can reduce the operation time by 23.33% and increase the particle size by 54.75%, owing to the high nucleation and particle growth rate during the initial time step. By employing an optimization approach based on the PBE model, this study provides detailed operational guidelines for batch and semi-batch co-precipitation, enabling the production of high-purity precursor materials from spent LIBs, while minimizing both operating time and maximum particle size.

Composite Materials Based on Spent Coffee Grounds and Paper Pulp

The need for biodegradable and environmentally friendly materials is increasing due to resource shortages and rising levels of environmental pollution. Agro-food waste, which includes coffee grounds, is of great interest in the production of composite materials due to its low cost, low density, easy availability, non-abrasive nature, specific properties such as reduced wear on the machinery used, the absence of residues and toxic products, and biodegradable characteristics. The composite materials developed that include coffee grounds exhibit good characteristics. This field is evolving and requires further improvements, but, at this moment, it can be stated that coffee grounds are not just waste but can be transformed into a highly efficient material applicable in various domains. In this study, composite materials were prepared using paper pulp as a matrix, coffee grounds as a filler material, and water as a binding agent. The obtained composite materials were evaluated through thermal analysis, SEM, EDX, ATR-FTIR, and rheological behavior analysis. The composite materials created from paper pulp and coffee grounds proved to be effective for use in the production of seedling pots. The seedling pots created in this study are produced at a low cost, are environmentally friendly, exhibit thermal stability, have good stability over time, and have good resistance to deformation.

Hierarchically mimicking outer tooth enamel for restorative mechanical compatibility

Tooth enamel, and especially the outer tooth enamel, is a load-resistant shell that benefits mastication but is easily damaged, driving the need for enamel-restorative materials with comparable properties to restore the mastication function and protect the teeth. Synthesizing an enamel analog that mimics the components and hierarchical structure of natural tooth enamel is a promising way to achieve these comparable mechanical properties, but it is still challenging to realize. Herein, we fabricate a hierarchical enamel analog with comparable stiffness, hardness, and viscoelasticity as natural enamel by incorporating three hierarchies of outer tooth enamel based on hierarchical assembly of enamel-like hydroxyapatite hybrid nanowires with polyvinyl alcohol as a matrix. This enamel analog possesses enamel-similar inorganic components and a nanowire-microbundle-macroarray hierarchical structure. It exhibits toughness of 19.80 MPa m1/2, which is 3.4 times higher than natural tooth enamel, giving it long-term fatigue durability. This hierarchical design is promising for scalable production of enamel-restorative materials and for optimizing the mechanical performance of engineering composites.

ECONOMIC ANALYSIS OF ANNUAL CROPS SUBJECT TO BIOAGRICULTURAL MANAGEMENT

The growing need for food worldwide causes changes in supply, which is not always concerned with the quality in which this food is being offered to consumers. That said, the concern with producing quality food, aiming at the maximum organic bases and available inputs, combined with the ability to produce one's own bioinputs on the farm, reduces dependence on external inputs, and greater control of production costs within the properties demonstrates a total internal interdependence for the production of food or raw materials. The research aims to evaluate the economic sustainability in the cultivation systems of the most important annual crops in the country; Soybeans, Corn, Wheat and Beans in the use of bioinputs on the farm to obtain a reduction in production costs. Research conducted in the municipality of Chapecó - SC during the 2021/2022 and 2022/2023 harvests. The research design is a factorial (3x6), factor A crop management, factor B different doses of basalt powder for the crops of Corn Harvest, Beans Off-season, Wheat Harvest and Soybean Harvest. Qualitative research on product/dose/target values. Economic results differed between production costing, attractive on a scale in R$/ha-¹ in biological management (A) and Bioagricultural (C) in the crops of corn, beans and soybeans. As well as the break-even point, the economic and financial results of the four crops evaluated were equivalent and positive in biological management (A). Expressively positive analysis in the economic indicators of profitability, between the different cultivable managements and doses of basalt powder.

Itaconic acid/cellulose-based hydrogels with fire-resistant and anti-freezing properties via vat photopolymerization 3D printing

Hydrogel-born materials have garnered significant interest due to their inherent flame retardant properties and eco-friendly characteristics. In light of the diminishing petroleum reserves and the escalating environmental challenges, there is an urgent impetus to exploit high-value applications of naturally occurring resources and to advance research in sustainable manufacturing technologies. In this vein, we describe an innovative and sustainable methodology for the development and production of flame-retardant hydrogels. This approach perfectly integrates renewable itaconic acid and cellulose derivatives with rapid vat photopolymerization (VP) 3D printing technology, which affords a green and efficient route for materials processing. Specifically, the biomass-based ink formulated for 3D printing demonstrates excellent visible-light curing properties, achieving a maximum double-bond conversion of 45.3 % within 10 min of exposure to visible-light LED under ambient conditions. Moreover, the resultant 3D-printed biomass-based hydrogels exhibit commendable flame-retardant performance, as evidenced by a V-0 flammability rating and a Limiting Oxygen Index (LOI) value of 60.2 %. They also possess desirable mechanical attributes (95.2 kPa) and exceptional thermal stability, enduring high temperatures for up to 12 min. Notably, these hydrogels exhibit remarkable freeze tolerance, maintaining their functionality even at profoundly low temperatures. This study demonstrates a novel strategy for the design and production of flame-retardant materials, contributing to the pursuit of green sustainability.

Effect of cement on carbonation behaviors of argon oxygen decarburization stainless steel slag (AODS)

Argon oxygen decarburization stainless steel slag (AODS) is an ideal CO2 feedstock. This study investigated the co-carbonation mechanisms of AODS and cement (A70C30) under slurry conditions. The results indicated that co-carbonation accelerates early carbonation but slows down later carbonation. The main reason was that low-Mg calcite formed in A70C30 at a slow rate when the pH dropped below 10 at the later stage. The carbonation rate was controlled by the incorporation of Mg into the calcite crystal structure. Co-carbonation also improved the stability of the formed carbonates by preventing the formation of metastable monohydrocalcite, which typically occurs during AODS carbonation. It was also pointed out that whether cement improved carbonation capacity lied in whether the co-precipitation behavior of Ca and Mg was enhanced. This study provides theoretical insights into the use of AODS-cement for CO2 capture in the production of building materials.
