Skin cancer is a growing global concern, strongly linked to ultraviolet (UV) radiation exposure, which is intensified by ozone depletion and lifestyle factors. Although synthetic sunscreens are widely used, many active ingredients raise serious environmental issues, including marine toxicity, bioaccumulation, and ecosystem disruption. This study investigates the use of polyphenol-rich plant extracts as sustainable, eco-friendly alternatives for skin photoprotection. Extracts from Cytisus triflorus L'Her, Cistus creticus L., and Ephedra alata subsp. alenda (Stapf) Trab., previously optimized through green extraction techniques, were evaluated for their sun protection factor (SPF), photostability under UV exposure, and anti-inflammatory properties. Both in vitro and in vivo analyses demonstrated that the extracts provided high SPF values (up to 30), retained stability after prolonged UV irradiation, and significantly reduced inflammatory responses. Compared to commercial sunscreens, these plant-based formulations offered comparable protective efficacy without the environmental burden of synthetic compounds. The study highlights the potential of renewable botanical resources as effective and sustainable alternatives in skincare, aligning with green chemistry principles and supporting environmentally responsible approaches to skin cancer prevention.

皮肤癌是一个日益受到全球关注的问题，与紫外线照射密切相关，臭氧消耗和生活方式因素加剧了紫外线照射。尽管合成防晒霜被广泛使用，但许多活性成分引发了严重的环境问题，包括海洋毒性、生物积累和生态系统破坏。本研究探讨了利用富含多酚的植物提取物作为可持续的、环保的皮肤光保护替代品。三花cytius L'Her，山竹，麻黄亚种提取物。日历（Stapf）之前通过绿色提取技术优化，评估了它们的防晒系数（SPF）、紫外线照射下的光稳定性和抗炎特性。体外和体内分析表明，提取物具有高SPF值（高达30），在长时间紫外线照射后保持稳定性，并显着减少炎症反应。与商业防晒霜相比，这些基于植物的配方提供了相当的保护功效，而没有合成化合物的环境负担。该研究强调了可再生植物资源作为有效和可持续的护肤替代品的潜力，与绿色化学原则相一致，并支持对环境负责的皮肤癌预防方法。

This study proposes valorization strategy of CO₂-delipidated hop residues using pressurized ethanol extraction (PLE-EtOH), targeting to obtain products with high xanthohumol (XN) concentration, also potent in vitro antioxidant and antimicrobial activity. The PLE-EtOH was optimized by coupling central composite design and response surface methodology (CCD-RSM) with Aspen Plus® simulation, providing an integrated approach of experimental design and physical process modeling for scalable biorefinery applications. The effects of PLE-EtOH temperature and extraction time on extraction yield, XN concentration and antioxidant responses were evaluated, identifying two optimal conditions: (1) 40 °C/15 min for XN-rich extracts (83.5 mg/g XN); and (2) 85 °C/18 min for maximum antioxidant recovery, yielding ∼2-fold higher extract quantity, total phenolic content (TPC) and enhanced oxygen radical absorbance capacity (ORAC). The XN-rich fraction exhibited strong ORAC activity (2624 mg TE/g extract) and significant inhibition of Staphylococcus aureus. The validated Aspen Plus® model closely aligned with CCD-RSM predictions, confirming process scalability and energetic feasibility under both optimal conditions. The recovery of diverse high-value bioactive fractions from hop processing by-products as a single feedstock aligns with sustainable extraction, green chemistry, and circular bioeconomy principles, offering promising applications in the food, nutraceutical, pharmaceutical, and cosmetic industries.

本研究提出了利用加压乙醇提取（le - etoh）对co2降解啤酒花残留物进行增殖的策略，目的是获得高含量的黄腐酚（XN），并具有较强的体外抗氧化和抗菌活性。通过将中心复合设计和响应面方法（CCD-RSM）与Aspen Plus®模拟相结合，对le - etoh进行了优化，为可扩展的生物炼制应用提供了实验设计和物理过程建模的集成方法。考察了萃取温度和萃取时间对提取率、XN浓度和抗氧化反应的影响，确定了两个最佳条件：(1)富XN提取物（83.5 mg/g XN）的提取温度为40°C/15 min；(2) 85°C/18 min达到最大抗氧化回收率，提取量、总酚含量（TPC）和氧自由基吸收能力（ORAC）提高约2倍。富xn组分表现出较强的ORAC活性（2624 mg TE/g提取物）和对金黄色葡萄球菌的显著抑制作用。经过验证的Aspen Plus®模型与CCD-RSM预测密切一致，确认了在两种最佳条件下的工艺可扩展性和能量可行性。从啤酒花加工副产品中回收多种高价值生物活性组分作为单一原料，符合可持续提取，绿色化学和循环生物经济原则，在食品，营养保健，制药和化妆品行业提供了有前途的应用。

Rare earth elements are essential components in renewable energy technologies and advanced functional materials. Despite their critical importance, they are typically present in low concentrations and are in increasingly high demand. Current mining and refining processes are energy intensive and cause significant environmental pollution. Therefore, there is an urgent need for eco-friendly, rapid, and effective analytical methods for their exploration. Traditional detection techniques are often costly, time-consuming, and non-portable. There remains a critical gap in the availability of rapid, sensitive, and economical sensors for rare earth element detection. In this study, we introduce a novel portable electrochemical detection system. This system utilizes a recombinant plasmid constructed using a codon-optimized gene to heterologously express a high-affinity protein that binds rare-earth ions. It integrates a graphene oxide-coated screen-printed electrode with an electrochemical workstation for the detection of rare-earth ions. Given that Yb has widespread applications among rare-earth elements, we selected Yb³⁺ for detection to validate the sensor's performance. The developed electrochemical biosensor exhibits a detection limit of 1.617 μM and demonstrates linear response across a concentration range of 10–90 μM (R² = 0.98). This rare-earth ion electrochemical sensor offers multiple advantages, including high sensitivity, a broad detection range, low cost, ease of use, portability, and potential for field deployment. The materials employed are environmentally friendly, aligning with green production requirements. The proposed method holds promise for practical applications in rare earth mineral exploration.

稀土元素是可再生能源技术和先进功能材料的重要组成部分。尽管它们至关重要，但它们的浓度通常很低，需求量却越来越大。目前的采矿和精炼过程是能源密集型的，并造成严重的环境污染。因此，迫切需要一种环保、快速、有效的分析方法来探索它们。传统的检测技术往往昂贵、耗时且不可携带。在快速、灵敏和经济的稀土元素检测传感器的可用性方面仍然存在重大差距。在这项研究中，我们介绍了一种新型的便携式电化学检测系统。该系统利用利用密码子优化基因构建的重组质粒异源表达一种结合稀土离子的高亲和力蛋白。它集成了一个氧化石墨烯涂层的丝网印刷电极和一个用于检测稀土离子的电化学工作站。考虑到Yb在稀土元素中有广泛的应用，我们选择Yb3+进行检测，以验证传感器的性能。该电化学生物传感器的检测限为1.617 μM，在10 ~ 90 μM的浓度范围内呈线性响应（R2 = 0.98）。这种稀土离子电化学传感器具有多种优势，包括高灵敏度、宽检测范围、低成本、易于使用、便携性和现场部署潜力。采用的材料是环保的，符合绿色生产的要求。该方法在稀土矿产勘查中具有实际应用前景。

Concrete sludge waste (CS), a by-product of concrete production, poses serious environmental challenges due to its disposal. This study aims to evaluate the potential of unground (UCS) and ground (GCS) CS as partial replacements for ground granulated blast-furnace slag (GBFS) in one-part alkali-activated composites (AACs), thereby advancing sustainable binder systems and reducing reliance on virgin raw materials. The experimental program included flowability, compressive and flexural strength, density, porosity, water absorption, sorptivity, and durability assessments under sulfate attack, freeze–thaw cycling, acid exposure, and elevated temperatures. UCS and GCS replaced GBFS at 5–30 % by weight, activated with sodium metasilicate. Microstructural analysis (SEM, XRD) was conducted to link performance outcomes with matrix development and reaction products. The results showed that UCS reduced flowability significantly (up to −38.5 % at 30 %), while GCS caused only minor changes (−4.6 % at 30 %). At 90 days, UCS at 5–10 % improved compressive strength by 15.5 % and 9.0 %, whereas higher UCS levels caused reductions. All GCS mixtures outperformed the reference, achieving up to 26.2 % strength gains and 46.8 % flexural improvement. Optimal GCS incorporation also enhanced resistance to sulfate, acid, freeze–thaw, and high-temperature exposures, while excessive UCS replacement reduced performance. Microstructural observations confirmed denser matrices with reduced porosity in GCS mixtures, while greenness assessment showed that 10–20 % GCS substitution achieves ∼3–4 % embodied CO₂ savings together with up to 26 % strength gains, thereby combining performance enhancement with sustainability benefits.

混凝土污泥废物是混凝土生产过程中产生的副产品，其处理方式对环境造成了严重的挑战。本研究旨在评估未磨碎的（UCS）和磨碎的（GCS） CS在单组分碱活性复合材料（AACs）中部分替代磨碎的颗粒状高炉渣（GBFS）的潜力，从而推进可持续的粘结剂体系，减少对原始原料的依赖。实验程序包括流动性、抗压和抗弯强度、密度、孔隙率、吸水率、吸附性和硫酸盐侵蚀、冻融循环、酸暴露和高温下的耐久性评估。用偏硅酸钠活化后，UCS和GCS以5 - 30%的重量取代GBFS。通过微观结构分析（SEM， XRD）将性能结果与基质发育和反应产物联系起来。结果表明，UCS显著降低了流动性（30%时降低了- 38.5%），而GCS只引起了轻微的变化（30%时降低了- 4.6%）。在90天内，5 - 10%的UCS可使抗压强度提高15.5%和9.0%，而更高的UCS水平则会降低抗压强度。所有GCS混合物的表现都优于对照，达到了26.2%的强度提高和46.8%的弯曲改善。最佳的GCS掺入也增强了抗硫酸盐、酸、冻融和高温暴露的能力，而过量的UCS更换会降低性能。微观结构观察证实，在GCS混合物中，密度更大的基质孔隙率更低，而绿色度评估表明，10 - 20%的GCS替代可以节省~ 3 - 4%的隐含二氧化碳，同时强度提高高达26%，从而将性能增强与可持续性效益结合起来。

In order to address the challenges of modifier penetration waste and pore blockage in the surface modification of porous biomass materials, this study proposes a solvent-free modification strategy based on solid-media surface force field regulation, otherwise known as the media-ball method. The directional spreading of liquid modifiers (Isopropyl tri(dioctyl pyrophosphate) titanate and Dodecyltrimethoxysilane) into micron-scale liquid films (thickness: 2–20 μm) is facilitated by the mechanical shearing forces and surface energy gradient of high-surface-energy media balls (stainless steel: 45.2 mJ/m², zirconia: 35.0 mJ/m²), These modifiers preferentially react with hydroxyl groups on the biomass outer surface. This approach has been shown to enhance surface reactivity in a synergistic manner, while preserving the porous structure. The experimental findings demonstrate that the modifier utilisation efficiency of the media-ball method is 3.8–7.4 times higher than that of traditional liquid-phase methods (XPS analysis reveals increased P content from 0.36 % to 2.22 %), with intact pore structure retention. The optimization of media-ball material (stainless steel) and size (2.0 mm) has been demonstrated to yield a 92.9 % success rate, concurrently reducing biomass powder adhesion to 1.0 %. The technology, operates through a "surface force field-mechanical synergy" mechanism, enabling efficient biomass surface functionalisation. This offers a green solution for developing environmental remediation materials and bio-based composites.

为了解决多孔生物质材料表面改性中存在的改性剂渗透浪费和孔隙堵塞问题，本研究提出了一种基于固体介质表面力场调节的无溶剂改性策略，也称为介质球法。高表面能介质球（不锈钢：45.2 mJ/m2，氧化锆：35.0 mJ/m2）的机械剪切力和表面能梯度促进了液体改性剂（三（焦磷酸二辛酯）钛酸异丙酯和十二烷基三甲氧基硅烷）在微米级液体膜（厚度：2 ~ 20 μm）上的定向扩散，这些改性剂优先与生物质外表面的羟基发生反应。这种方法已被证明以协同方式增强表面反应性，同时保持多孔结构。实验结果表明，介质球法的改性剂利用率是传统液相法的3.8 ~ 7.4倍（XPS分析显示，P含量从0.36%提高到2.22%），且孔隙结构保持完整。介质球材料（不锈钢）和尺寸（2.0 mm）的优化已被证明可以产生92.9%的成功率，同时将生物质粉末附着力降低到1.0%。该技术通过“表面力场-机械协同”机制运行，实现了高效的生物质表面功能化。这为开发环境修复材料和生物基复合材料提供了绿色解决方案。

As the most widely used construction material globally, concrete faces increasing demand for amended mechanical, durability and sustainability performance. Fiber reinforcing has become a viable approach to overcome concrete's inherent drawbacks such as brittleness and low tensile strength. In this study, the effects of incorporating hybrid polypropylene fiber (PPF) and date palm fiber (DPF) on concrete's fresh and hardened properties were investigated. Response Surface Methodology (RSM) served as the tool to formulate an experimental program, allowing for a systematic examination of the effects of fiber doses on the fresh and hardened properties of the concrete. Results revealed that while DPF enhanced specific mechanical properties due to its high aspect ratio and fibrous structure, it reduced workability and density because of its affinity for moisture and poor bonding with the cement matrix. Conversely, PPF improved ductility and reduced water absorption but had minimal impact on compressive strength. Hybridization of DPF and PPF offered a balanced approach to achieving optimal mechanical performance and durability, though careful dosage optimization was required to mitigate adverse interactions. Mathematical models developed through RSM demonstrated high accuracy in predicting concrete behavior, validated by experimental results with average errors below 6 %. Multi-objective optimization using desirability functions identified an optimal mix containing 0.7 % PPF and 0 % DPF yielding the best compromise between strength enhancement and reduced water absorption. The optimization result does not negate the role of DPF in strength and durability but reflects the trade-offs in fiber interactions. While DPF enhances mechanical properties, its hydrophilic nature increases water absorption, making PPF alone more effective for the desired balance in this study. This research underscores the potential of hybrid fiber-reinforced concrete systems in sustainable construction, emphasizing the need for scientific design approaches like RSM to optimize performance characteristics effectively.

混凝土作为全球应用最广泛的建筑材料，其力学性能、耐久性和可持续性等方面的要求日益提高。纤维增强已成为克服混凝土脆性和抗拉强度低等固有缺陷的可行方法。研究了掺入混合聚丙烯纤维（PPF）和枣椰树纤维（DPF）对混凝土新鲜性能和硬化性能的影响。响应面法（RSM）作为制定实验程序的工具，允许系统地检查纤维剂量对混凝土的新鲜和硬化性能的影响。结果表明，DPF由于其高纵横比和纤维结构而提高了特定力学性能，但由于其对水分的亲和力和与水泥基体的粘结性差，降低了和易性和密度。相反，PPF提高了延性，降低了吸水率，但对抗压强度的影响最小。DPF和PPF的杂交提供了一种平衡的方法来实现最佳的机械性能和耐久性，尽管需要仔细优化剂量来减轻不良相互作用。通过RSM建立的数学模型在预测混凝土性能方面显示出很高的准确性，实验结果验证了平均误差低于6%。使用期望函数进行多目标优化，确定了含有0.7% PPF和0% DPF的最佳混合物，从而在强度增强和减少吸水率之间取得最佳折衷。优化结果并没有否定DPF在强度和耐久性中的作用，而是反映了纤维相互作用的权衡。虽然DPF提高了机械性能，但其亲水性增加了吸水率，使得PPF单独使用更有效地达到本研究中所期望的平衡。这项研究强调了混合纤维增强混凝土体系在可持续建筑中的潜力，强调需要像RSM这样的科学设计方法来有效地优化性能特征。

Fiber reinforcing has become a viable approach to overcome concrete's inherent drawbacks such as brittleness and low tensile strength. In this study, the effects of incorporating hybrid polypropylene fiber (PPF) and date palm fiber (DPF) on concrete's fresh and hardened properties were investigated. Response Surface Methodology (RSM) served as the tool to formulate an experimental program, allowing for a systematic examination of the effects of fiber doses on the fresh and hardened properties of the concrete. Results revealed that while DPF enhanced specific mechanical properties due to its high aspect ratio and fibrous structure, it reduced workability and density because of its affinity for moisture and poor bonding with the cement matrix. Conversely, PPF improved ductility and reduced water absorption but had minimal impact on compressive strength. Hybridization of DPF and PPF offered a balanced approach to achieving optimal mechanical performance and durability, though careful dosage optimization was required to mitigate adverse interactions. Mathematical models developed through RSM demonstrated high accuracy in predicting concrete behavior, validated by experimental results with average errors below 6 %. Multi-objective optimization using desirability functions identified an optimal mix containing 0.7 % PPF and 0 % DPF yielding the best compromise between strength enhancement and reduced water absorption.

This study presents a sustainable strategy for the synthesis of benzofurans, starting from simple, unprotected phenols via Pd-catalyzed C–H functionalization. The developed methodology addresses key environmental challenges commonly associated with such transformations, including the use of toxic solvents, homogeneous catalysts, and stoichiometric amounts of inorganic oxidants. By employing γ-valerolactone (GVL), a bio-based solvent, in combination with a heterogeneous Pd/C catalyst and molecular oxygen at atmospheric pressure as the terminal oxidant, we offer a significantly greener alternative. The sustainability of this protocol was compared with existing C–H functionalization methods using the CHEM21 green metrics toolkit and E-factor analysis. Mechanistic insights supported by DFT calculations highlight the key role of cyclization and reductive elimination steps in the catalytic cycle. The newly defined protocol established a marked improvement in environmental performance, aligning well with the principles of green chemistry by promoting the use of renewable resources and reducing environmental impact in the synthesis of pharmaceutically relevant heterocycles.

Sewage sludge pyrolysis provides a sustainable way to turn waste into valuable products, mitigating environmental issues linked to traditional disposal. This research combines Aspen Plus® process simulation, experimental validation, and Artificial Neural Network (ANN) modeling to improve key pyrolysis parameters for better biochar yield and quality. The simulation used feedstock analysis through proximate and ultimate tests, modelled with the Peng–Robinson–Boston–Mathias (PR-BM) equation of state within temperature ranges of 350–650 °C, heating rates of 5–10 °C min⁻¹, and residence times of 30–60 min. Experimental and simulation results were in close agreement, showing that increasing temperature reduced biochar yield while enhancing non-condensable gas production through intensified devolatilization and secondary cracking. Bio-oil yield peaked at 500 °C, whereas higher temperatures improved biochar fixed carbon content and thermal stability. The ANN model with three input variables and ten hidden neurons achieved predictive accuracy, and temperature was identified as the dominant factor. Profiler-based optimization indicated that optimal biochar and quality occur at 450–500 °C, 5–7.5 °C min⁻¹, and 45–60 min. A techno-economic analysis confirmed 500 °C to be the most cost-effective condition, with a payback period of 4.4 years and an estimated net annual profit of USD 500,000. These results demonstrate the potential of AI-assisted pyrolysis modeling for scalable, resource-efficient sewage sludge treatment within a circular bioeconomy.

污泥热解提供了一种可持续的方式，将废物转化为有价值的产品，减轻了与传统处理相关的环境问题。本研究结合Aspen Plus®过程模拟、实验验证和人工神经网络（ANN）建模来改进关键热解参数，以提高生物炭的产量和质量。在温度范围为350-650°C，加热速率为5-10°C min - 1，停留时间为30-60分钟的条件下，采用Peng-Robinson-Boston-Mathias （PR-BM）状态方程对原料进行了近似和终极测试分析。实验结果与模拟结果一致，表明温度升高降低了生物炭的产率，但通过加速脱挥发和二次裂解提高了不凝气的产率。生物油产率在500°C时达到峰值，而更高的温度提高了生物炭的固定碳含量和热稳定性。采用3个输入变量和10个隐藏神经元的人工神经网络模型实现了预测精度，并将温度确定为主导因素。基于profiler的优化表明，在450-500°C、5-7.5°C min - 1和45-60 min时，生物炭和质量最佳。技术经济分析证实，500°C是最具成本效益的条件，投资回收期为4.4年，预计年净利润为50万美元。这些结果证明了人工智能辅助热解建模在循环生物经济中可扩展、资源高效的污水污泥处理方面的潜力。

In recent years, green analytical chemistry has gained significant importance in the scientific community and socioeconomic development. Various metric tools have been developed to evaluate the greenness of analytical methods. However, despite scientific progress, the knowledge gap regarding the green determination of complex emerging contaminants remains unresolved. In this present review, a comparative greenness and whiteness assessment of methodologies for the determination of high-polar pesticides such as glyphosate and its metabolite aminomethylphosphonic acid (AMPA) was conducted. The Analytical GREEness Calculator (AGREE) and RGB 12 algorithm were used as metrics of greenness and whiteness, respectively. From the green metric used, scores between 0.14 and 0.50 were obtained for the selected methodologies. Regarding the whiteness metric, the analyzed methodologies showed values from 69.8 % to 93.2 %. Advantages and opportunity areas were described thanks to the metric tools employed. The obtained findings suggest that the analytical procedures implemented over the last decade have advanced in the green determination of the selected analytes. Furthermore, there is limited research on the green and white assessment methods used to determine glyphosate and AMPA. To delve deeper into this type of study, which employs metrics to demonstrate improvements over conventional analytical methodologies, could significantly enhance awareness of sustainable chemistry research.

近年来，绿色分析化学在科学界和社会经济发展中得到了极大的重视。已经开发了各种度量工具来评估分析方法的绿色度。然而，尽管科学进步，关于复杂的新兴污染物的绿色测定的知识差距仍然没有解决。本文对草甘膦及其代谢物氨基甲基膦酸（AMPA）等高极性农药的绿度和白度测定方法进行了比较评价。分别使用分析绿色计算器（AGREE）和RGB 12算法作为绿色和白色的度量标准。从所使用的绿色度量标准中，所选方法的得分在0.14到0.50之间。关于白度度量，分析方法显示值从69.8%到93.2%。由于所使用的度量工具，优势和机会领域被描述。获得的结果表明，在过去十年中实施的分析程序在选定分析物的绿色测定方面取得了进展。此外，用于确定草甘膦和AMPA的绿色和白色评估方法的研究有限。这类研究采用指标来证明对传统分析方法的改进，深入研究可以显著提高对可持续化学研究的认识。

Ion adsorption clay (IAC) is a major source of rare earth elements (REEs). However, the leaching process of REEs using ammonium sulfate as a leaching agent faces various challenges, including, environmental pollution, co-leaching of impurities, and low permeability through the clay. Therefore, this review explores the development of sustainable, selective, and efficient leaching agents for REEs leaching from IAC. The review covers, leaching mechanisms using inorganic and organic salts to leach REEs from all phases with various phenomena such as ion exchange, complexation, and reduction. Consequently, the leaching agents, aids, and technologies on an industrial as well as laboratory scale have been discussed. From extensive literature, it has been revealed that the use of alternative leaching agents such as bioleaching agents, organic acids, and biodegradable surfactants can reduce environmental impacts and improve the selectivity and leaching efficiency of REEs. The integration of permeability enhancers, including cationic polysaccharides, is crucial for overcoming low permeability and swelling in IAC. This review highlights the importance of the advancement of leaching agents to achieve more sustainable and efficient leaching of REEs.

离子吸附粘土（IAC）是稀土元素的主要来源。然而，以硫酸铵为浸出剂的稀土元素浸出过程面临着环境污染、杂质共浸、粘土渗透性低等诸多挑战。因此，本文对从IAC中浸出稀土的可持续、选择性和高效浸出剂的开发进行了综述。本文综述了利用无机盐和有机盐从各相中浸出稀土元素的浸出机理，包括离子交换、络合和还原等各种现象。因此，在工业和实验室规模上讨论了浸出剂、助浸剂和浸出技术。大量文献表明，使用生物浸出剂、有机酸和可生物降解表面活性剂等替代浸出剂可以减少对环境的影响，提高稀土的选择性和浸出效率。包括阳离子多糖在内的渗透性增强剂的整合对于克服IAC中的低渗透性和肿胀至关重要。本文综述了浸出剂的发展对实现稀土的可持续和高效浸出的重要性。
