Scrap aluminum (Al) alloy recycling is critical for energy conservation and decreasing carbon emissions. Conventional remelting process does not remove alloying elements, severely limiting the value and applications of recycled Al. To overcome this limitation, this study develops an efficient process for recovering pure Al from scrap Al alloys via soluble anode electrolysis in a designed MgCl 2 -KCl-NaCl (MKN) molten salt system. Real-time monitoring of the electrolysis process, time-dependent characterization of cathodic deposits, and electrochemical analyses reveal a three-stage cathodic deposition mechanism in the MKN molten salt system: initial underpotential deposition of Mg 2+ transitions to co-deposition of Mg 2+ and Al 3+ , and ultimately to exclusive reduction of Al 3+ , which is driven by progressive Al 3+ accumulation. The introduction of AlCl 3 proves pivotal, simultaneously enhancing Al 3+ deposition efficiency while effectively suppressing Mg 2+ co-reduction. Systematic optimization identifies 12.5 wt% AlCl 3 addition, 500 °C, and 0.15 A/cm 2 as the ideal operational parameters, achieving recycled Al with 99.84 wt% purity. The soluble anode electrolysis process in the MKN molten salt system represents an efficient and scalable alternative to conventional remelting. The developed process is capable of producing recycled Al with purity comparable to that of primary Al while addressing critical sustainability challenges in the Al industry.

Renewable lubricant base oils derived from biomass can effectively mitigate environmental challenges while exhibiting exceptional properties. Herein, we propose a novel approach for the synthesis of ester-based and alkane-based renewable lubricant base oils, achieving an impressive yield of up to 99%. This strategy involves the utilization of methyl oleate and biomass-derived aromatics through two distinct chemistries: alkylation and alkylation followed by hydrodeoxygenation (HDO). Among the various Lewis acid catalysts screened, AlCl3 demonstrated superior performance and achieved a remarkable maximum yield of 99% for the alkylation product under the optimized reaction conditions. Subsequent hydrodeoxygenation (HDO) of these alkylation products using the Ir-ReOx/SiO2 catalyst resulted in the production of alkane-based lubricant base oils, with an impressive maximum yield of 96.3%. The molecular size and branching of ester-based and alkane-based products can be finely adjusted by employing diverse aromatic compounds during the alkylation process, thereby enabling tuning of their lubricant properties. The as-synthesized base oils exhibit superior properties to petroleum-derived group III base oils and demonstrate comparable performance to synthetic ester and PAO base oils. The presented strategy for synthesizing renewable base oils offers a sustainable alternative to petroleum-derived counterparts, thereby potentially mitigating greenhouse gas emissions.

Ethnopharmacological relevance ShengHui decoction (SHD), a traditional Chinese herbal formula, has long been used clinically to mitigate Alzheimer’s disease (AD), demonstrating significant efficacy in alleviating cognitive impairment. However, its molecular mechanisms remain insufficiently understood. Aim of the study To clarify the effects of SHD on oxidative stress–related markers and inflammatory cytokines in an aluminum chloride (AlCl 3 )-induced zebrafish model of AD and as well as uncover its underlying mechanisms in alleviating oxidative stress and neuroinflammation.. Materials and methods Ultra-performance liquid chromatography–tandem mass spectrometry (UPLC-MS/MS) was employed to identify the bioactive constituents of SHD. Behavioral tests and histopathological analyses were then conducted to evaluate the effects of SHD (0.74, 1.48, and 2.96 mg/mL) on apoptosis and amyloid-beta (Aβ) deposition in an AlCl 3 -induced AD zebrafish model. Biochemical assays and enzyme-linked immunosorbent assay were used to quantify superoxide dismutase (SOD), malondialdehyde (MDA), glutathione peroxidase (GSH-Px), tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), IL-1 beta (IL-1β), and IL-18.. Western blot analysis was performed to determine the protein expression of nuclear factor erythroid 2–related factor 2 (Nrf2), heme oxygenase-1 (HO-1), NAD(P)H quinone dehydrogenase 1 (NQO1), nuclear factor-kappa B p65 (NF-κB p65), phosphorylated NF-κB p65 (p–NF-κB p65), and NOD-like receptor family pyrin domain containing 3 (NLRP3). Results UPLC–MS/MS profiling identified phenolic acids, saponins, lignans/coumarins, flavonoids, and aliphatic alcohols as the main constituents of SHD. SHD significantly ameliorated cognitive deficits and histopathological abnormalities in AlCl 3 -induced zebrafish. Moreover, SHD attenuated oxidative stress by upregulating Nrf2, HO-1, and NQO1 expression, while downregulating AlCl 3 -induced levels of NF-κB p65, p–NF-κB p65, NLRP3 and pro-inflammatory factors. Conclusions SHD effectively improved cognitive performance and reduced AD-like pathological lesions in AlCl 3 -induced zebrafish. Importantly, SHD exhibits both antioxidant and anti-inflammatory activities by activating the Nrf2/HO-1 axis and inhibiting NF-κB signaling, thereby alleviating oxidative stress and neuroinflammatory responses in AD. These findings provide experimental evidence supporting SHD as a potential therapeutic agent for AD, and substantiate the traditional Chinese medicine principle of tonifying the kidney and replenishing essence in the treatment of AD.

Plant polyphenols, especially their flavonoid subclass are important bioactive compounds. Simultaneous determination of total flavonoids (TFs) and total polyphenols (TPs) is crucial for studying the distribution characteristics of polyphenols. Traditional methods for determining TFs and TPs require complicated operational procedures, and reported flow injection analysis (FIA) methods have also been limited due to inefficiencies caused by carrier changing and system resetting. Simultaneous determination of TFs and TPs is difficult to achieve with the existing methods. Therefore, in this study, a merging-zone FIA technique was developed for the simultaneous determination of TFs and TPs based on the study of the AlCl3 and Folin-Ciocalteu colorimetric reaction mechanisms. The FIA parameters were optimized by univariate experimental design, and standard curves for TFs and TPs were established in the concentration ranges of 10-800 mg/L and 15-400 mg/L, respectively. The limit of detection of the proposed FIA method for TFs and TPs was 3.114 mg/L and 4.166 mg/L, and the limit of quantitation was 10.38 mg/L and 13.89 mg/L. The relative standard deviations were below 2.5% (n=15). The recoveries of spiked sample ranged from 93.89% to 103.8%, and the sample throughput was approximately 67 h-1. The proposed method was successfully applied to the simultaneous determination of TFs and TPs in nine plants, and the analytical results were in good agreement with those of traditional methods. This study provides a rapid, automated and reliable method for simultaneous quantitative analysis, showing high application potential for simultaneous evaluation of these two bioactive compounds in various plants.

The stability of the lithium-metal/solid electrolyte interface remains a critical challenge in the development of all-solid-state lithium-metal batteries (ASSLMBs), as it directly influences their cycling performance, rate capability, and safety. Here, a thin, flexible, and lithium-stable sulfide electrolyte membrane is presented with high ionic conductivity (3.25 × 10 −3 S cm −1 ) and low electronic conductivity (1.45 × 10 −9 S cm −1 ) at room temperature, prepared with an AlCl 3 coating in a low-cost wet process. The in situ formation of a lithiophilic Li-Al alloy and a lithiophobic LiCl layer at the interface creates a stable dual-layer structure, effectively suppressing Li-dendrite growth and enhancing Li-transport across the interface. Symmetric Li/Li cells with this coated membrane exhibit exceptional cycling stability, operating for over 10000 h at 0.5 mA cm −2 . ASSLMBs assembled with a LiNi 0.8 Co 0.1 Mn 0.1 O 2 cathode and a metallic lithium anode exhibit excellent cycling performance, highlighting the potential of this coating strategy to stabilize the Li/solid electrolyte interface and expedite the commercialization of ASSLBs.

The transition to clean energy necessitates the development of alternative or complementary battery chemistries to lithium-ion batteries. Aluminium (Al) metal batteries (AMBs) are a promising option owing to their high energy density and advantages in terms of abundance, recyclability, manufacturability and sustainability. However, state-of-the-art AMBs rely primarily on electrolytes featuring chloroaluminate anions such as Al 2 Cl 7 − . Unfortunately, such electrolytes create a disparity between achievable energy density and potential, in addition to having high corrosivity, high cost, high viscosity and poor transport kinetics. Here we break this paradigm by formulating an organochloro electrolyte with AlCl 3 salt in dipropyl ether (DPE) solvent. Notably, this AlCl 3 /DPE electrolyte shows no corrosion behaviour towards stainless steel current collectors during 90-day soaking. It enables stable cycling of the Al anode for over 2,000 h at 0.2 mA cm −2 and a high Coulombic efficiency of 99.85%, and prototype Al//Mo 6 S 8 full cells survive 300 cycles. Underlying these unprecedented performances is the unique organochloro solvation structure, AlCl 2 (DPE) 2 + , which is desolvatable and immobilizes free Cl − . By extending the horizon of electrolyte design into the organic domain, this work addresses the notorious issues facing AMBs and paves the way for the implementation of multivalent rechargeable batteries.

Graphene-based materials are cathodes of Al-ion batteries and have attracted the attention of researchers worldwide. However, reasons for self-discharge in Al/graphene batteries have not been studied in depth. In the present work, a pseudo-capacitive reaction is proposed to be a probable cause of the self-discharge. Quantitative analysis of the capacitance process and diffusion-control process is critical for the pseudo-capacitive behavior in Al/graphene batteries. Two self-supported graphene cathodes (R h -GOP and R n -GOP) were successfully produced from graphene oxides (GO) reduced with hydriodic acid and hydrazine vapor, respectively. R h -GOP and R n -GOP cathodes enabled the delivery of considerably high specific capacities of 81.5 mAh g -1 and 92.8 mAh g -1 , at the current density of 2 A g -1 . In addition, the activation processes of both materials were observed during 200 cycles of the charge-discharge process. From a quantitative perspective, the ratios of faradaic pseudo-capacitance to the total capacity of the R h -GOP and R n -GOP cathode were 48.6% and 38.5%, respectively, at a scanning rate of 5.0 mV s -1 . It is found that the proportion of faradaic pseudo-capacitance will increase as cyclic voltammetry scanning increases, which indicates the existence of pseudo-capacitance being the reason why it an Al/graphene battery has to be charged-discharged at high current densities to maintain normal operation.

To promote the functionalization of chitosan-based films, lignin separated from Moso bamboo using type IV deep eutectic solvents (DESs; FeCl 3 /glycerol (Gly), AlCl 3 /Gly, and CuCl 2 /Gly) was incorporated into chitosan to prepare lignin/chitosan composite films. For comparison, lignin pretreated with an aqueous NaOH solution was prepared and used for forming a film. The systematic characterization of lignin samples and lignin/chitosan composite films was performed using advanced analytical techniques. Gel permeation chromatography showed that the type-IV-DES-pretreated lignin sample possessed a lower molecular weight and more uniform structure than the NaOH-pretreated lignin sample, which was more conducive to increasing the compatibility between lignin and chitosan. 31 P nuclear magnetic resonance spectroscopy and two-dimensional heteronuclear correlation results revealed that the excellent antioxidant activity of lignin following AlCl 3 /Gly pretreatment was due to the high phenolic hydroxyl group content (1.16 mmol/g). Moreover, the free-radical scavenging capacity of the resulting DES-pretreated lignin/chitosan composite film reached 83.12 %, which was 3.4-fold higher than that of the pure chitosan film. In general, type-IV-DES-pretreated lignin was superior to NaOH-pretreated lignin in terms of enhancing the ultraviolet-shielding ability, antioxidant capacity, and antibacterial properties of the chitosan films. Notably, these films have great potential for use in food packaging applications.

Based on the high safety and low costs, molten salt batteries (Na-S battery, liquid metal battery, ZEBRA battery, etc.) have received more and more attention as large-scale electrical storage technology. However, the high operating temperature of molten salt batteries is still one of the roadblocks that impeded their practical application. Here we present the novel Ni-graphite molten salt battery based on outstanding electrochemical reversibility of the Ni/NiCl 2 redox and intercalation/de-intercalation chemistry of chloroaluminate anions in graphite. By using the low-cost, quaternary inorganic molten salt AlCl 3 /KCl/NaCl/LiCl as electrolyte, the as-designed Ni-graphite battery possesses low operating temperature of 95 °C, and average voltage about 1.7 V. The Ni-graphite battery delivers stable specific capacity of 174 mAh/g at 500 mA/g after 120 cycles, with the capacity retention rate of 98%. In addition, the Ni-graphite battery also shows low material costs about 113.6 $/kWh and high electrode energy density of 289 Wh/kg. This work develops an advanced molten salt battery with low operating temperature and high energy density, as well as provides an alternative means of developing future large-scale power storage equipment based on molten salt batteries.
