This review examines the increasing application of artificial intelligence (AI) and/or machine learning (ML) in microalgae processes, focusing on their ability to improve production efficiency, yield, and process control. AI/ML technologies are used in various aspects of microalgae processes, such as real-time monitoring, species identification, the optimization of growth conditions, harvesting, and the purification of bioproducts. Commonly employed ML algorithms, including the support vector machine (SVM), genetic algorithm (GA), decision tree (DT), random forest (RF), artificial neural network (ANN), and deep learning (DL), each have unique strengths but also present challenges, such as computational demands, overfitting, and transparency. Despite these hurdles, AI/ML technologies have shown significant improvements in system performance, scalability, and resource efficiency, as well as in cutting costs, minimizing downtime, and reducing environmental impact. However, broader implementations face obstacles, including data availability, model complexity, scalability issues, cybersecurity threats, and regulatory challenges. To address these issues, solutions, such as the use of simulation-based data, modular system designs, and adaptive learning models, have been proposed. This review contributes to the literature by offering a thorough analysis of the practical applications, obstacles, and benefits of AI/ML in microalgae processes, offering critical insights into this fast-evolving field.

Large-Current CO2 Electromethanation Through Active Hydrogen Regulation Over Carbon Nitride.

Electromethanation of CO2 has received intensive attention due to its high calorific value and convenient storage along with transportation to accommodate industrial demands. However, it is limited by sluggish multi-step proton-coupled electron transfer kinetics and undesired *H coupling under high current density, posing great challenges to its commercialization. Herein, carbon nitride (CN) with superior hydrogen adsorption ability is used as an active-hydrogen adsorption and supply material. Through a facile liquid-assisted exfoliation and electrostatic self-assembly strategy to strengthen its interfacial contacts with Cu2O catalysts, yielding a strengthened CH4 production 52 times higher than that of pristine Cu2O. Flow-cell test ultimately achieved FECH4 and remarkably CH4 partial current density of 61% and 561mAcm-2, respectively. With in situ ATR-FTIR spectra and DFT calculations, it is established that strengthened interfaces enabled abundant *H tethered by ─C─N═C─ sites in CN nanosheets and oriented to the *CO hydrogenation to *CHO and *CHx on Cu species. This work reveals the profound influence of fine-expanded interfaces with dimensional materials on the product distribution and yield through the active-hydrogen management, which is of reference value for other small-molecule electro-polarization dominated by the proton-coupled electron transfer (PCET) process (e.g., N2, O2, etc.).

Exploring symbiotic pathways: Unveiling the evolution and key drivers of China's human-environment relationship

Rapid urbanization increased human demand for natural resources, disrupting the balance between human and environment. This disruption led to regional environmental degradation, frequent natural disasters, and severe challenges in achieving sustainable development goals. In this context, fostering human and environment harmony is essential. However, research on quantifying their relationship and exploring the driving factors and mechanisms at a national fine spatial scale remains insufficient. This study endeavours to address this gap by constructing China's eco-environmental quality index (EQI) and human activity intensity (HAI) evaluation index systems with a 1 km resolution. Furthermore, the study utilizes the four-quadrant model and trend analysis to reveal the human-environment relationship, and employs the Bayesian network model to explore key drivers and underlying mechanisms influencing their relationship, aiming to foster harmonious human-environment interaction. Our results show that: (1) Both EQI and HAI increased over time, with their high values concentrated on the southeast side of the Hu Line but low on the northwest side. (2) The proportions of coordination and running-in areas increased while those of degradation and conflict areas declined, with 36.77% of the regions showing positive synergy during 2000–2020, indicating that China's human-environment relationship tended toward coordination. (3) Bayesian network analysis identified land use intensity, GDP, fraction vegetation coverage, and population density as critical factors affecting human-environment relationship. From a quadrant-based analysis, natural and eco-environmental factors including precipitation, water yield, and net primary productivity mainly influenced the spatial distribution of coordination and running-in intensity, while socioeconomic factors like population density and GDP primarily drove the spatial distribution of degradation and conflict intensity. This study finally proposed tailored management recommendations which would provide scientific support to facilitate the coordination and harmony of regional human-environment relationship.

Global Versus Local? A Study on the Synergistic Relationship of Ecosystem Service Trade-Offs from Multiple Perspectives Based on Ecological Restoration Zoning of National Land Space—A Case Study of Liaoning Province

Clarifying the trade-offs and synergies of ecosystem services in Liaoning’s ecological restoration zones is crucial for strengthening the positioning of ecological restoration zones and optimizing ecosystem services. This study is based on “Liaoning Provincial Land Spatial Planning (2021–2035)” and divides the area into ecological restoration zones. We utilized the InVEST model, ArcGIS Pro, and Geoda in this study to quantify five ecosystem services (Soil Conservation, Carbon Storage, Habitat Quality, Water Yield, and Food Production) and constructed an evaluation framework to assess the trade-offs and synergies of ecosystem services at both global and local levels. The conclusions are as follows: (1) The global relationships among ecosystem services in different ecological restoration zones are ranked as: strong trade-offs (35.51%) > weak trade-offs (33.17%) > low synergies (29.09%) > high synergies (2.24%); (2) The area exhibiting synergistic relationships between pairs of local ecosystem services in ecological restoration zones is larger than the area exhibiting trade-offs; (3) The strongest synergy is observed between water yield and soil conservation, while the most significant trade-off occurs between food production and soil conservation. These relationships exhibit similar spatial characteristics in the WSFR, SWCR, and WCR zones; (4) The proportion of areas showing trade-offs and synergies differs between global and local scales.

Catalytic vapor phase upgrading of sawdust pyrolysis using metal oxide catalysts: The support effect

Biocrude derived from biomass is unstable and has limited applications and vapor-phase upgrading of biomass pyrolysis over a catalyst can enhance bio-oil quality and yield, yet catalyst deactivation due to coke formation remains a major challenge. This study explores the effects of different magnesium oxide (MgO) catalysts supported on ZSM-5, Al2O3, ZrO2, TiO2 on the pyrolysis product yield, composition, and the extent of coke formation. Studies were conducted in a fixed-bed reactor at 550 °C at two different catalyst to biomass loadings (C/B) of 1:6, and 1:1. Non catalytic pyrolysis of sawdust resulted in the biocrude, gas, and char yields of ∼32 wt%, ∼29 wt%, and ∼39 wt% respectively. At a low C/B ratio, pyrolysis product yields were approximately comparable to those under non-catalytic conditions. However, at a high C/B ratio, biocrude yield decreased significantly with increase in gas yield, while char yield showed only minor changes. Using ZSM-5 and Al2O3 supported catalysts, low C/B ratios significantly increased phenolic content in the biocrude (∼58%). In contrast, higher C/B ratios enhanced the hydrocarbons (∼10%) and aromatics (∼32%) content, reducing phenolics and thereby lowering the biocrude's overall oxygen content, enhancing its stability. TiO2 and ZrO2 supports produced higher proportions of lower carbon chain length compounds, though with reduced hydrocarbon content compared to ZSM-5. ZSM-5 supported catalysts yield a high proportion of aromatic compounds, attributed to the synergy between the acidic sites of ZSM-5 and the basic sites of MgO that favored conversion of phenolics to aromatics through dehydroxylation and demethoxylation. Overall, this study highlights the influence of different catalyst supports in catalytic vapor phase upgrading of sawdust derived biocrude to selectively optimize bio-oil composition, increasing fuel or chemical potential while addressing coke formation.

Valorization of White Lupin Straw Through Mild Dilute Acid Hydrothermal Treatment: A Sustainable Route for Monosaccharide and 5-Hydroxymethylfurfural Production

This study investigates the potential use of white lupine straw (WLS), an underutilized agricultural by-product, as a raw material to produce valuable biochemicals such as monosaccharides and 5-hydroxymethylfurfural (5-HMF) through hydrothermal pretreatment. The aim was to optimize mild reaction conditions to maximize the recovery of these products while minimizing degradation. The hydrothermal treatment of WLS in subcritical water with trace amounts of sulfuric acid was performed, followed by a two-step approach to evaluate the yields of hemicellulose and 5-HMF. The highest monosaccharide yield (163 g/kg) was achieved at temperatures between 174 and 181 °C and a holding time of 7–14 min, while the 5-HMF production was 139.9 g/kg at 199–203 °C and after 0.5–4.5 min. These results suggest that optimal 5-HMF production also increases the remaining solid residue. This study highlights the feasibility of WLS as a sustainable, low-cost biomass resource. It highlights the balance between temperature and time to maximize valuable product yields. The results contribute to advancing biorefinery processes by demonstrating that WLS can be effectively converted into bioethanol precursors and industrial chemicals, supporting circular bioeconomy principles and providing an environmentally friendly alternative to burning crop residues.

Yeast β‒fructosidase-catalyzed synthesis of tyrosol fructoside in mono- and biphasic organic–aqueous systems

Abstract Tyrosol and its glycosides offer cell protection from oxidative stress and various health benefits. In this study, Saccharomyces cerevisiae β‒fructosidase potential for synthesizing tyrosol fructoside in mono- and biphasic solvent systems was assessed using 1.5 M sucrose, 10 g/L or 25 g/L tyrosol, at pH 6 and 40°C. Monophasic organic–water systems were designed with nine organic solvents (log P ranging from -1.35 to 0.5). Initial rates of sucrose hydrolysis, tyrosol and sucrose transfructosylation and tyrosol fructoside yields were evaluated. The hydrolytic activity increased with the addition of 5–15% organic solvents, revealing no clear correlation between the log P and sucrose hydrolysis rate. Simultaneously, transfructosylation reaction rates decreased, despite lower water activity. Notably, the effect of log P on tyrosol transfructosylation was observed in 70:30 (v/v) aqueous/organic biphasic systems. Differences in tyrosol fructoside synthesis in six biphasic reaction media were attributed to the unequal solubility of tyrosol in the organic phase, impacting its availability for the enzyme. Product yields were either similar to or lower than those in aqueous media, with no tyrosol fructoside partitioning into the organic phase, thus no effect of product stripping could be observed. Consequently, transfructosylation of tyrosol proves most effective in organic solvent-free media.

Light‐Responsive Aldehyde‐Reduction Catalysis Through Catalyst Encapsulation

We report a light‐responsive tetrahedral metal–organic capsule that binds a perrhenate catalyst, which is released selectively upon irradiation with 350 nm light, turning on the catalytic reduction of organic carbonyls by hydrosilanes. The catalytic activity can be switched off by heating at 75 °C for 2.5 h, which stimulates capsule reformation and catalyst re‐encapsulation. Multiple on‐off cycles were shown, with a clear relationship between product yield and light irradiation time. Encapsulation thus enables the coupling of light‐responsiveness to catalysis in a manner that might be generalized to other catalysts and capsules.

Thermo-amplifier circuit in probiotic E. coli for stringently temperature-controlled release of a novel antibiotic

Peptide drugs have seen rapid advancement in biopharmaceutical development, with over 80 candidates approved globally. Despite their therapeutic potential, the clinical translation of peptide drugs is hampered by challenges in production yields and stability. Engineered bacterial therapeutics is a unique approach being explored to overcome these issues by using bacteria to produce and deliver therapeutic compounds at the body site of use. A key advantage of this technology is the possibility to control drug delivery within the body in real time using genetic switches. However, the performance of such genetic switches suffers when used to control drugs that require post-translational modifications or are toxic to the host. In this study, these challenges were experienced when attempting to establish a thermal switch for the production of a ribosomally synthesized and post-translationally modified peptide antibiotic, darobactin, in probiotic E. coli. These challenges were overcome by developing a thermo-amplifier circuit that combined the thermal switch with a T7 RNA Polymerase. Due to the orthogonality of the Polymerase, this strategy overcame limitations imposed by the host transcriptional machinery. This circuit enabled production of pathogen-inhibitory levels of darobactin at 40 °C while maintaining leakiness below the detection limit at 37 °C. Furthermore, the thermo-amplifier circuit sustained gene expression beyond the thermal induction duration such that with only 2 h of induction, the bacteria were able to produce pathogen-inhibitory levels of darobactin. This performance was maintained even in physiologically relevant simulated conditions of the intestines that include bile salts and low nutrient levels.Graphical

Overcoming nucleotide bias in the nonenzymatic copying of RNA templates.

The RNA World hypothesis posits that RNA was the molecule of both heredity and function during the emergence of life. This hypothesis implies that RNA templates can be copied, and ultimately replicated, without the catalytic aid of evolved enzymes. A major problem with nonenzymatic template-directed polymerization has been the very poor copying of sequences containing rA and rU. Here, we overcome that problem by using a prebiotically plausible mixture of RNA mononucleotides and random-sequence oligonucleotides, all activated by methyl isocyanide chemistry, that direct the uniform copying of arbitrary-sequence templates, including those harboring rA and rU. We further show that the use of this mixture in copying reactions suppresses copying errors while also generating a more uniform distribution of mismatches than observed for simpler systems. We find that oligonucleotide competition for template binding sites, oligonucleotide ligation and the template binding properties of reactant intermediates work together to reduce product sequence bias and errors. Finally, we show that iterative cycling of templated polymerization and activation chemistry improves the yields of random-sequence products. These results for random-sequence template copying are a significant advance in the pursuit of nonenzymatic RNA replication.

Comparison of biocrude production and characterization from Persian Gulf Sargassum angustifolium macroalgae, Chlorella vulgaris, and Spirulina sp. microalgae using hydrothermal liquefaction (HTL): Potential of solid residue for heavy metal adsorption.

Biocrude production using the hydrothermal liquefaction (HTL) process is a promising alternative energy source to conventional fossil fuels. Using algal feedstock types in this process has many advantages, such as not needing to dry a high moisture content, which consumes much energy. In this study, the feedstock types of Sargassum angustifolium macroalgae, Chlorella vulgaris, and Spirulina sp. microalgae affected the yield and property of the biocrude products were obtained at 350 °C, 18 MPa, 35 min residence time, and 8.7 wt% feedstock concentration. The biocrude yields from Sargassum angustifolium, Chlorella vulgaris, and Spirulina sp. were 26.15 wt%, 55.8 wt%, and 56.32 wt%, respectively. These values revealed that feedstock's carbon and nitrogen contents have the most effect on the biocrude yield, and increasing these elements increases the biocrude yields. Moreover, the properties of the produced biocrudes revealed that the main components were esters, organic acids, ketones, aldehydes, aromatic rings, amides, amines, alcohol, and phenol. The thermal gravimetric analysis (TGA) results of biocrudes showed the decomposition of more organic components at the 175-600 °C temperature range. Also, the simulated distillation of biocrudes showed that most biocrude components from Sargassum angustifolium and Chlorella vulgaris are the same as heavy naphtha, and the biocrude from Spirulina sp. is similar to kerosene. These results showed that the produced biocrude from Chlorella vulgaris has a higher yield and quality than other resources. The quality of the biocrude produced from Sargassum angustifolium is comparable to other biocrudes. Besides, the higher solid-phase yield produced from Sargassum angustifolium was used as a heavy metal biosorbent. The effect of adsorbent concentration and adsorption time on adsorption efficiency was investigated. Results showed that the maximum adsorption efficiency of Fe2+, Zn2+, and Mn2+ was 47.07 wt%, 48.93 wt%, and 42.47 wt%, respectively, at 2 g/L adsorbent concentration and 60 min adsorption time, and the structure destruction of the solid phase was carried out under the biosorption process.

Biochar co-compost increases the productivity of Brassica napus by improving antioxidant activities and soil health and reducing lead uptake.

Lead (Pb) is a serious toxic metal without any beneficial role in the biological system. Biochar (BC) has emerged as an excellent soil amendment to mitigate Pb toxicity. The impact of BC co-compost (BCC) in mitigating the toxic impacts of Pb has not been studied yet. Therefore, this study aimed to evaluate the potential of BC and BCC in improving the growth, physiological, and biochemical traits of Brassica napus and soil properties and reducing health risks (HR). The study was comprised of different Pb concentrations (control and 100 mg kg-1) and organic amendments (control, BC, compost, and BCC). The results indicated that Pb stress reduced the growth, photosynthetic pigments, seed yield, and oil contents by increasing hydrogen peroxide (H2O2) production and Pb uptake and accumulation in plant tissues and decreasing photosynthetic pigment and nutrient availability. The application of BCC alleviated the adverse impacts of Pb and improved seed production (40.24%) and oil yield (11.06%) by increasing chlorophyll a (43.18%) and chlorophyll b (25.58%) synthesis, relative water content (23.89%), total soluble protein (TSP: 23.14%), free amino acids (FAA: 26.47%), proline (30.98%), APX (40.90%), CAT (32.79%), POD (24.93%), and SOD (33.30%) activity. Biochar co-compost-mediated increase in seed and oil yield was also linked with a reduced accumulation of Pb in plant parts and soil Pb availability and improved the soil-available phosphorus, potassium, total nitrogen, soil organic carbon (SOC), and microbial biomass carbon (MBC). Furthermore, BCC also reduced the bioaccumulation concentration, daily metal intake, hazard index, and target hazard quotient. In conclusion, application of BCC can increase the growth, yield, and oil contents of Brassica napus by improving the physiological and biochemical traits and soil properties and reducing the Pb uptake.

Facile Synthesis of Fluorescent Carbon Quantum Dots with High Product Yield Using a Solid-Phase Strategy.

The liquid-phase method is the most commonly utilized strategy for synthesizing fluorescent carbon quantum dots (CQDs). However, the liquid-phase synthesis of CQDs faces challenges such as low yield, complex purification, and the use of toxic solvents, which limit large-scale production and practical applications. In this study, fluorescent CQDs with a high product yield of 78% were synthesized using glucose as a carbon source through a green and facile one-step solid-phase approach, without solvents or post-treatment. A systematic study of the structure and fluorescence properties of the synthesized CQDs was conducted using various characterization techniques. The results indicated that the mean size of obtained CQDs was 4.1 nm, and that their surface had abundant oxygen-containing functional groups, resulting in favorable water solubility. The synthesized CQDs exhibited excitation-dependent fluorescence, with optimal excitation and emission wavelengths at 358 and 455 nm, respectively. Additionally, the CQDs solution showed bright blue fluorescence under 365 nm UV light, with a quantum yield of 6.21% and a fluorescence lifetime of 3.02 ns. This study offers valuable insights into the green and efficient synthesis of fluorescent CQDs powder.

Response of Onion to Deficit Irrigation Levels at Different Growth Stages on Yield and Water Productivity

The Ethiopian vegetable sub-sector, particularly onion, is crucial for the economy due to its high productivity and ease of cultivation. However, water scarcity in arid and semi-arid regions hinders its expansion. This study conducted at Wondo Genet Agricultural Research Center aimed to investigate the impact of deficit irrigation levels at various growth stages on onion yield and water productivity. The experiment employed a split plot design with four crop growing stages and three deficit irrigation levels. Results revealed that deficit irrigation significantly affected onion growth parameters and yield components. Bulb diameter, number of leaves per plant, and total bulb yield 5.84 cm, 6.85, 23.26 t/ha, respectively, were notably influenced by deficit irrigation levels, with the highest yields observed under full irrigation. Additionally, water use efficiency varied with deficit irrigation application timing, with the highest efficiency recorded during the maturation stage. Overall, deficit irrigation during initial and maturation stages at 55% ETc application level emerged as the most viable option, ensuring sustainable crop production in water-scarce areas. These findings underscore the importance of adopting deficit irrigation strategies to optimize water use efficiency and enhance onion yield in Ethiopia's vegetable sub-sector.

Benchtop 19F Nuclear Magnetic Resonance (NMR) Spectroscopy-Optimized Knorr Pyrazole Synthesis of Celecoxib and Mavacoxib, 3-(Trifluoromethyl) Pyrazolyl Benzenesulfonamides, Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)

Fluorinated organic compounds have demonstrated remarkable utility in medicinal chemistry due to their enhanced metabolic stability and potent therapeutic efficacy. Several examples exist of fluorinated non-steroidal anti-inflammatory drugs (NSAIDs), including diflunisal, flurbiprofen, and trifluoromethylated pyrazoles celecoxib and mavacoxib. These trifluoromethylated pyrazoles, which are most commonly constructed through the cyclocondensation of a trifluorinated 1,3-dicarbonyl and an aryl hydrazine, are also found in numerous other drug candidates. Here, we interrogate the effects of solvents and the presence of Brønsted or Lewis acid catalysts on catalyzing this process. We highlight the utility of benchtop 19F NMR spectroscopy in enabling the real-time quantification of reaction progress and the identification of fluorinated species present in crude reaction mixtures without the need for cost-prohibitive deuterated solvents. Ultimately, we find that the reaction solvent has the greatest impact on the rate and product yield, and also found that the relationship between the keto-enol equilibrium of the dicarbonyl starting material pyrazole formation rate is highly solvent-dependent. More broadly, we describe the optimization of the yield and kinetics of trifluoromethylpyrazole formation in the synthesis of celecoxib and mavacoxib, which is made possible through high-throughput reaction screening on benchtop NMR.

Analysis on Degradation Mechanism and Product Recycle of Ex-service Wind Turbine Blades by Hydrothermal Liquefaction.

The recycling of ex-service wind turbine blades (EWTBs) presents a significant challenge for the future. Hydrothermal liquefaction (HTL) has emerged as a promising approach for the recovery of resins and glass fibers (GFs) from EWTBs. This study offers a comprehensive analysis of the separation mechanisms and product characteristics under the catalytic effect of an acidic medium during the HTL tests. The primary factors were identified as hydrothermal temperature and H2SO4 concentration. The acidic medium facilitated disruption of the resin's structure by supplying hydronium ions, while temperature played a crucial role in determining the yield of oil-phase products. Operating conditions of 280 °C and 0.6 mol/L H2SO4 resulted in an oil-phase yield of 98.2%. The cleavage of cross-linked C-N and C-O-C bonds reacted with hydrogen ions to produce stable compounds, primarily phenol and p-cumyl alcohol. Based on these findings, two distinct mechanisms of resin depolymerization were proposed, depending on the sequential cleavage of C-O-C and C(benzene ring)-C(isopropyl) bonds. Intermediates, including bisphenol A and 2-propanol,1,3-diphenoxy-, were generated. They further decomposed into smaller units, eventually forming phenol. Moreover, temperature was found to be a critical factor in determining the strength of recycled glass fibers (RGFs). The optimal conditions of 260 °C and 0.6 mol/L H2SO4 concentration were identified as being capable of achieving complete resin depolymerization while preserving high-strength RGFs. These innovative findings provide valuable insights into the development of low-temperature, high-efficiency methods for the full-component recovery of EWTBs, offering significant guidance for future recycling efforts.

One-pot green synthesis, biological evaluation, and in silico study of pyrazole derivatives obtained from chalcones

Abstract Several chalcones and their pyrazole derivatives have been synthesized using traditional methods under microwave (MW) and ultrasonic (US) irradiation. The latter were synthesized using US-assisted and MW-assisted one-pot techniques. The use of this technology led to a reduction in reaction time and energy consumption, as well as an increase in the yield of the final products, which means more efficient synthesis. An in silico study was conducted and the plant growth-stimulating effects of the synthesized compounds were revealed. To study the growth-regulating activity of the synthesized compounds, a study of aqueous suspensions at a concentration of 50 and 25 mg·L−1 was carried out on the viability, germination, and growth of seeds.
