Employing response surface methodology, we identified optimal extraction conditions for maximizing the yield of total phenolic content from . The optimal conditions were determined to be a temperature of 195.43 °C, a reaction time of 18.82 min, and a solid/liquid ratio of 0.032 g/mL. The optimized extract (OSE) was analyzed, revealing a total phenol content of 29.01 ± 0.28 mg phloroglucinol equivalent/g and a total flavonoid content of 10.33 ± 0.48 mg quercetin equivalent/g. Ultra-performance liquid chromatography–electrospray ionization quadrupole time-of-flight mass spectrometry revealed 64 phenolic compounds, including phenolic acids, flavonoids, and other polyphenols. Nuclear magnetic resonance spectroscopy confirmed the presence of polysaccharides and phenolic compounds in OSE. Furthermore, residue analysis indicated the potential for biofuel production from the remaining biomass, contributing to a zero-waste biorefinery process. This study establishes a theoretical foundation and provides practical guidelines for the efficient extraction and processing of phenolic compounds from , indicating the feasibility of a sustainable biorefinery process using SWT.

Water purification is a crucial task in the advancement of human civilization as it plays a significant role in environmental preservation. So far, complex processes and various methods have been utilized to treat contaminated water. Water treatment using radicals via oxidation–reduction is a chemically advanced oxidation process. This reaction is carried out using a metal oxide and a radical precursor. Metals react with oxygen molecules to produce oxides, peroxides, or superoxides. The oxide forms of transition metals have been studied as catalysts and as alternatives to precious metals due to their high stability and low price. This review summarizes recent research activities focused on water treatment using transition metal oxides, bimetallic oxides, and metal oxides doped with co-catalysts.

The main aim of this work is to determine performance ranking of asphaltene controlling chemical additives using Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) method. The performance of four chemicals namely; Cocamide Diethanolamide (CDEA), Dodecyl Benzene Sulphonic Acid (DBSA), Salicylic Acid, and Toluene were evaluated on crude oil of Pakistani origin. The performance of chemical additives was evaluated before and after the initiation of asphaltene precipitation as chemical performance during pre-treatment and post-treatment stage respectively. TOPSIS method was used to incorporate different parameter of experiment as criteria and further the weight of criteria importance were altered to yield rankings of chemicals under different scenarios. Three cases were developed to implement TOPSIS method. For case – 1 and Case – 2, generally, DBSA found to be the best additive while for case – 3 Salicylic acid and Toluene was proved to be rank 1 additive. The alteration of weight importance of criteria affects the chemical additive ranking. This research work highlighted the importance of decision making process for the selection of chemical additives considering the desired specific role of chemical additive to be used for the prevention and mitigation of asphaltene deposition in crude oil.

Lead’s high density (density of ∼ 11.34 g/cm) facilitates X-ray attenuation, but its mass and toxicity limit applicability. Therefore, it is essential to replace Pb with lighter and nontoxic shielding materials; however, alternative shielding usually exhibits inferior performance to Pb. In this study, we successfully developed efficient radiation shielding sponges with a light weight (density of ∼ 1 g/cm) and a coin shape (thickness of 3 mm and diameter of 25 mm) by combining polymeric Polydimethylsiloxane (PDMS), sulfated tungsten oxide (S-WO), and bismuth halides. The synthesized S-WO powder, PDMS/S-WO and PDMS/S-WO/BiI sponges are examined using numerous techniques, such as XRD, FE-SEM with EDX/mapping, HR-TEM with EDX/mapping, XPS, BET, TGA, FT-IR and mechanical properties analysis. The XRD patterns revealed no significant peak shifts, indicating that sulfation had no discernible impact on the crystal structure or phase composition of WO. SEM analysis of PDMS/S-WO, PDMS/S-WO/BiI sponge indicated an even distribution of S-WO and bismuth halide particles within the PDMS matrix. Our novel porous sponge matrices of PDMS and S-WO effectively adsorbed bismuth halide salts on their porous surfaces, forming intimate interfaces and uniform dispersions in the composites. The shielding sponge exhibits high X-ray attenuation. Coin-shaped PDMS/S-WO/BiI demonstrated 90.2 % X-ray shielding efficiency at 60 kV, a top value for non-heavy-metal shields. This study investigates the development and characterization of PDMS/S-WO/BiI composite materials aimed at enhancing X-ray shielding effectiveness. The composite leverages the high atomic number and density of S-WO and BiI to improve X-ray attenuation, while the flexibility and chemical stability of PDMS provide mechanical robustness and ease of fabrication. Through a series of experimental evaluations, we demonstrate that the PDMS/S-WO/BiI composite exhibits superior X-ray shielding capabilities compared to conventional materials. This work demonstrates significant progress in flexible, high-performance X-ray shielding. The approach provides a foundation for developing lightweight, radiation-protective materials using doped metal oxides and halide salts.
铅的高密度（密度为 11.34 克/厘米）有利于 X 射线衰减，但其质量和毒性限制了其适用性。因此，必须用更轻、无毒的屏蔽材料来替代铅，但替代屏蔽材料的性能通常不如铅。在这项研究中，我们将聚合物聚二甲基硅氧烷（PDMS）、硫酸化氧化钨（S-WO）和卤化铋结合在一起，成功研制出重量轻（密度为 1 克/厘米）、形状为硬币（厚度为 3 毫米，直径为 25 毫米）的高效辐射屏蔽海绵。合成的 S-WO 粉末、PDMS/S-WO 和 PDMS/S-WO/BiI 海绵采用多种技术进行了检测，如 XRD、带 EDX/绘图的 FE-SEM、带 EDX/绘图的 HR-TEM、XPS、BET、TGA、FT-IR 和机械性能分析。XRD 图谱没有发现明显的峰值偏移，表明硫化对 WO 的晶体结构或相组成没有明显影响。对 PDMS/S-WO、PDMS/S-WO/BiI 海绵的 SEM 分析表明，S-WO 和卤化铋颗粒在 PDMS 基体中分布均匀。我们的新型 PDMS 和 S-WO 多孔海绵基质能有效地在其多孔表面吸附卤化铋盐，在复合材料中形成亲密的界面和均匀的分散。这种屏蔽海绵具有很高的 X 射线衰减性。硬币形 PDMS/S-WO/BiI 在 60 千伏电压下的 X 射线屏蔽效率为 90.2%，是非重金属屏蔽的最高值。本研究调查了 PDMS/S-WO/BiI 复合材料的开发和特性，旨在提高 X 射线屏蔽效果。这种复合材料利用 S-WO 和 BiI 的高原子序数和密度来改善 X 射线衰减，而 PDMS 的柔韧性和化学稳定性则提供了机械坚固性和易于制造性。通过一系列实验评估，我们证明了 PDMS/S-WO/BiI 复合材料与传统材料相比具有更出色的 X 射线屏蔽能力。这项工作表明，在柔性、高性能 X 射线屏蔽方面取得了重大进展。该方法为开发使用掺杂金属氧化物和卤化物盐的轻质辐射防护材料奠定了基础。

Li-X zeolites have been widely used as nitrogen-selective adsorbents in oxygen concentrators. However, the synthesis of Li-X zeolites requires an excessive amount of Li for ion exchange, and Li-X zeolites are vulnerable to humid conditions because of their high affinity for water vapor. To solve these problems, a ZSM-5 zeolite exchanged with both Cu and Li (CuLi-ZSM-5) was developed for N adsorption. CuLi-ZSM-5 achieved a high Li content (Li/Al =0.84) despite the use of a smaller amount of Li in its ion-exchange procedure and exhibited higher N uptake (0.81 mmol/g) at 298 K than the Li-X zeolite (0.69 mmol/g). This is possibly because the Li in CuLi-ZSM-5 is effectively distributed at sites accessible for N adsorption. In addition, CuLi-ZSM-5 had higher N/O selectivity in the low-pressure range and a much lower affinity for water vapor than the Li-X zeolite, resulting in significantly lower HO/N selectivity. CuLi-ZSM-5 has the potential to be a new economical N-selective adsorbent with low interference from water vapor.

Aluminium-air (Al-air) batteries have been considered as one of the most promising next-generation energy storage devices. In this study, we investigated the effect of structural changes in the main body of porous aluminium anode on the electrochemical performance under the constraints of the 3D printing process using both simulation and experimental methods. By analysing the simulation results under the constraint of 3D printing process, we found that the variation of the base fillet radius affects the dimensional deviation of the porous aluminium anode. As the radius of the fillet increases, the degree of warpage deformation gradually decreases. For this reason, we experimentally verified the self-corrosion rate, electrochemical and discharge properties of aluminium anodes under the same process parameters. The test results are consistent with the simulation analysis. With the increase of fillet radius, the self-corrosion rate of anode gradually decreases and the electrochemical activity gradually increases. Meanwhile, the discharge voltage was as low as 1.55 V in the periphery without rounded corners, and increased by 1.3 % and 3.2 % when the periphery radius was 1 mm and 2 mm, respectively. This research result provides a new method for other researchers to further improve the overall performance of aluminium-air batteries.
铝-空气（Al-air）电池一直被认为是最有前途的下一代储能设备之一。在本研究中，我们采用模拟和实验两种方法，研究了在三维打印工艺的约束下，多孔铝阳极主体结构变化对电化学性能的影响。通过分析三维打印工艺约束下的模拟结果，我们发现基底圆角半径的变化会影响多孔铝阳极的尺寸偏差。随着圆角半径的增大，翘曲变形程度逐渐减小。因此，我们通过实验验证了相同工艺参数下铝阳极的自腐蚀速率、电化学性能和放电性能。试验结果与模拟分析结果一致。随着圆角半径的增加，阳极的自腐蚀速率逐渐降低，电化学活性逐渐增加。同时，外围无圆角时的放电电压低至 1.55 V，当外围半径为 1 mm 和 2 mm 时，放电电压分别增加了 1.3 % 和 3.2 %。这项研究成果为其他研究人员进一步提高铝空气电池的整体性能提供了一种新方法。

In alignment with the principles of green chemistry as well as environmental sustainability, herein two novel double-armed corrosion inhibitors (CIs) 5,5′-((1,4-phenylenebis(azanylylidene))bis(methanylylidene))bis(2-methoxyphenol) (PAMM-1) and 6,6′-((1E,1′E)-(1,4-phenylenebis(azanylylidene))bis(methanylylidene))bis(2-methoxyphenol) (PAMM-2) were synthesized through energy-efficient ultrasound assisted synthetic pathway. Both of the CIs exhibited excellent corrosion inhibition properties toward the protection of mild steel (MS) in static HCl medium. Remarkably, the highest inhibition efficiency (IE) achieved through electrochemical analysis was 94.7% and 93.4% for 4 mM of PAMM-1 and PAMM-2, respectively. Morphological analysis has been evaluated through field emission scanning electron microscopy (FE-SEM), atomic force microscopy (AFM), X-ray photoelectron spectroscopy (XPS), and water contact angle (WCA) measurements. The protective performance of CIs have been validated using density functional theory (DFT) and non covalent interaction (NCI) in a perceptive way. To delve deeper into the molecular level insights, the interactions of the CIs with corrosive elements and metal atoms in a real corrosive environment have been analyzed using molecular modelling, indicating spontaneous adsorption of the green CIs with high binding energy (947.37 kJ/mol). The present research is shedding light on how the IE is influenced by different positional substituents (–OCH and –OH) within the molecular scaffold, resulting in the ultimate achievement of ‘4E factors’: energy, economy, environment, and efficiency.

Remarkably, the highest inhibition efficiency (IE) achieved through electrochemical analysis was 94.7% and 93.4% for 4 mM of PAMM-1 and PAMM-2, respectively. Morphological analysis has been evaluated through field emission scanning electron microscopy (FE-SEM), atomic force microscopy (AFM), X-ray photoelectron spectroscopy (XPS), and water contact angle (WCA) measurements. The protective performance of CIs have been validated using density functional theory (DFT) and non covalent interaction (NCI) in a perceptive way. To delve deeper into the molecular level insights, the interactions of the CIs with corrosive elements and metal atoms in a real corrosive environment have been analyzed using molecular modelling, indicating spontaneous adsorption of the green CIs with high binding energy (947.37 kJ/mol). The present research is shedding light on how the IE is influenced by different positional substituents (–OCH and –OH) within the molecular scaffold, resulting in the ultimate achievement of ‘4E factors’: energy, economy, environment, and efficiency.","PeriodicalId":363,"journal":{"name":"Journal of Industrial and Engineering Chemistry","volume":"22 1","pages":""},"PeriodicalIF":6.1,"publicationDate":"2024-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141931197","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, a series of butterfly-shaped fulvene based acceptor molecules ( and ) with A2-π-A1-π-A2 configuration was designed to explore their photovoltaic behavior. This designing strategy was carried out incorporating extended end-capped acceptors at the peripherals of conjugated tetraphenyl fulvene core (). Density functional theory (DFT) and time-dependent DFT (TD-DFT) approaches were conducted on the designed compounds to elucidate their structure–property relationships, photovoltaic and opto-electronic characteristics. Various analyses like HOMO-LUMO energy gaps, absorption maxima, density of states, binding energies of electrons and holes, transition density matrix, and open-circuit voltage, were employed to investigate photovoltaic behaviour of the entitled compounds. Interestingly, all the designed molecules ( and ) exhibited remarkable photovoltaic characteristics, such as minimal bandgap values in range of 2.275–2.310 , red-shifted absorption maxima (range 715–722 ) with good open-circuit voltage values. Moreover, all the derivatives exhibit lower binding energies with a decreasing order of Particularly, reveal the smallest exciton binding energy of 0.546 . These findings suggest that the entitled newly tetraphenyl fulvene based NFAs specifically hold significant potential as highly efficient candidates in the field of organic solar cells.

Effluent derived from spent lithium-ion batteries (LIBs) electrolyte or discarded ionic liquids (ILs) is a potentially resource of hexafluorophosphate (PF) which can be recovered through solvent extraction. In this study, an efficient extraction approach was proposed to recover the hexafluorophosphate from solutions. A basic investigation on the interactions between extractants and hexafluorophosphate was firstly carried out using density functional theory (DFT), which demonstrated the stability of the extracted complex structure. The effects of extractant (Alamine336) and modifier, common anions and metallic ions in waste-streams, initial pH, and temperature on the extraction efficiency were explored. The results showed that 96.16 % of hexafluorophosphate could be extracted and transferred into organic phase using Alamine336/modifier as extractant under optimal conditions (0.15 mol/L of Alamine336 and 0.25 mol/L of modifier). The organic phase exhibited an excellent extraction capability of >95 % under optimal condition. Moreover, it was found that the use of sodium hydroxide as stripping reagent presented a superb stripping and cycling properties. Thermodynamic analysis and spectral data indicated that PF was extracted into the organic phase in the form of RNH⋅PF, which is a spontaneous exothermic process. The novel extraction method provides a broad application perspective for the removal and recovery of valuable hexafluorophosphate from aqueous system.
