Graphical Interc-Al-ation for batteries : A high-capacity cathode with porous α-MnSe is designed for rechargeable aluminum batteries. The fundamental reaction mechanism of the α-MnSe cathode is deeply researched in the manuscript. The synergistic effect of nanostructure and porosity could efficiently mitigate volume changes of the α-MnSe and enhance intercalation kinetics of Al 3+ , which sheds new light on the establishment of advanced energy-storage devices. Aluminum batteries (ABs) have been considered as a viable candidate for new-generation energy-storage devices due to its low cost and high theoretical volumetric capacity. Despite these advantages, the large-scale application of ABs is constrained by scarce options of suitable cathode materials. Herein, three-dimensional nanostructured α-MnSe microspheres with porous properties are reported as a cathode for ABs. The nanosized and porous structure of α-MnSe could offer numerous open channels and the short ionic transport path, which would efficiently mitigate volume changes and enhance electrochemical reaction kinetics. Moreover, the pseudocapacitive characteristic of Al 3+ storage in α-MnSe contributes to the fast kinetics of the cathode. It is demonstrated that the reversible Al 3+ insertion/extraction occurs in the α-MnSe cathode during the cycling process. The resulting aluminum battery based on the α-MnSe cathode, AlCl 3 /[EMIm]Cl ionic liquid electrolyte, and aluminum anode exhibits an ultrahigh reversible capacity of 408 mA h g −1 at 0.2 A g −1 . Even for a current density at 1 A g −1 , a discharge capacity of 131 mA h g −1 could be retained with a Coulombic efficiency of 97 % over 150 cycles. This strategy has referential significance in aspects of the selection of compatible cathode for ABs.

In view of global warming and following fossil energy consumption caused by the using of heavy-loaded air conditioners, smart windows, which can intelligently regulate solar radiation, became a highly anticipated strategy to slow down the pressure. As most of the traditional hydrogel-based smart windows abruptly switch between transparent and opaque making a sudden change in temperature and light, we established a poly- N -isopropylacrylamide (PNIPAM) thermo-responsive hydrogel system with additional cross-linking of chitosan and Al 3+ , which exhibited a smooth thermo-response during heating and a novel recovery hysteresis during cooling. By enabling additional gentle transition in translucency, we are able to retain a comfortable indoor temperature/lightness balance during an increase in outdoor temperature, in avoidance of sudden indoor darkness at elevated temperature. By enabling additional control in the thermo-response hysteresis, this methodology provides a solution to continuously shield the dazzling afternoon sunshine until a comfortable outdoor temperature is reached. And the response degree and response temperature can be adjusted by the contents of chitosan and Al 3+ , respectively, so that the material can be customized personally. Moreover, we discovered that the hydrogel-based smart window system constructed by this methodology bears notably enhanced strength, toughness and conductivity, making it a comprehensively promising candidate for customizable smart windows.

Fluoride coating can reduce the ignition temperature, enhance the burning rate and inhibit the agglomeration of aluminum powder. However, the addition of non-energetic fluoride can reduce the energy of aluminum powder. In this study, for the first time, 3-Perfluorohexyl-1,2-epoxypropane (PFHP) was coated on the surface of aluminum powder, which reacted with glycidyl azide polymer (GAP) in situ to form core–shell Al@PFHP@GAP. Compared with raw aluminum powder, Al@PFHP@GAP not only significantly reduced ignition temperature (about 150 °C), but also greatly improved the combustion efficiency (from 87.7% to 97.6%). Besides, the heat of combustion was also greatly increased by 6.3%, compared with that of raw aluminum powder. Such performances were outstanding among the existing coated Al. In addition, the formation of coating shell effectively improved the hydrophobicity and corrosion resistance of the aluminum powder. In a word, our derived Al@PFHP@GAP provided a novel rationale for aluminum powder with greatly enhanced combustion performance.

Multi-ion-responsive probes are particularly attractive due to their high detection efficiencies and potential cost reductions, while there still remains the formidable challenge of discriminating different metal ions in pure aqueous media. Herein, a novel imidazolium chloride ionic liquid-grafted rhodamine B salicylaldehyde hydrazone (IMI-SARhBH) was rationally designed and developed as a promising multi-ion-responsive probe for the colorimetric detections and individual identifications of Cu 2+ and Al 3+ in 100% aqueous solutions. Benefitting from the remarkably hydrophilic nature of the grafted ionic liquid , the IMI-SARhBH was highly water-soluble, and showed excellent sensing performances for detections of Cu 2+ and Al 3+ under pure aqueous conditions in terms of high sensitivity, satisfactory selectivity, and strong anti-disturbance ability. More importantly, dissociation of the grafted ionic liquid in water made the probe positively charged, which caused electrostatic repulsion between itself and metal ions and thus offered the chance to differentially recognize Cu 2+ and Al 3+ . The Cu 2+ was repelled relatively weakly by IMI-SARhBH and thus identified quickly (<1 min), while the sensing detection of Al 3+ required a longer time (5 h) due to the relatively stronger electrostatic repulsion. Accordingly, a new and convenient method for individual identifications of Cu 2+ and Al 3+ from Cu 2+ –Al 3+ -coexisted solution was also successfully established.

The precise separation of macerals is the premise and foundation for the efficient utilization of coal resources, and flotation is the separation method with the greatest industrial potential. The differences in the surface hydrophobicity of macerals provide the basis for flotation, but the complexity of their surface properties makes separation challenging. In this study, sub-bituminous coal was used to obtain vitrinite and inertinite , and a detailed analysis was carried out on the samples. The surface morphologies of vitrinite and inertinite were observed in the QI TM (quantitative imaging) mode of AFM (atomic force microscope) to explore the adsorption of the reagents. The effect of the reagents on the interaction forces between the coal particles and bubbles was measured to reveal the change in hydrophobicity. The attachment performance of macerals under different reagent treatments was investigated using a laboratory-built apparatus. Overall, the results demonstrated that the difference in zeta potential between vitrinite and inertinite was a viable approach for separating the macerals. CTAB adsorption on coal samples changed the surface morphology and the interaction force between particles and bubbles. Interestingly, CTAB adsorption on the gas–liquid interface decreased the interaction force. Vitrinite and inertinite attachment performances were enhanced when Al 3+ and SDS were used simultaneously.

In this paper, a new strategy was presented for fluorescence labeling and imaging Al 3+ in live cells with excess aluminum ions using thiolated fluorescence gold nanoclusters (Au NCs). The glutathione (GSH)-capped Au NCs were prepared via a green, facile one-pot method in aqueous solution and displayed excellent stability, ultrasmall size, monodispersity, and larger Stokes shift, which exhibits a relatively weak fluorescence at 650 nm Al 3+ -induced fluorescence enhancement of the GSH-Au NCs can be observed due to Al 3+ -triggered aggregation-induced emission (AIE) effect, which allows the role of GSH-Au NCs as a fluorescence light-up probe for detection of Al 3+ . Moreover, it was demonstrated that the fluorescence probe for Al 3+ showed a wide detection range from 100 to 600 μM and good selectivity against other metal ions and common biomolecule. Furthermore, due to the advantages of excellent biocompatibility, low toxicity, red emission and high specificity, the proposed GSH-Au NCs fluorescence probes are suitable for the imaging of high concentrations of aluminum ions in cells, which can be applied to the diagnosis of cellular aluminum poisoning.

Molten salt aluminum-sulfur batteries are based exclusively on resourcefully sustainable materials, and are promising for large-scale energy storage owed to their high-rate capability and moderate energy density; but the operating temperature is still high, prohibiting their applications. Here we report a rapid-charging aluminium-sulfur battery operated at a sub-water-boiling temperature of 85 °C with a tamed quaternary molten salt electrolyte. The quaternary alkali chloroaluminate melt – possessing abundant electrochemically active high-order Al-Cl clusters and yet exhibiting a low melting point – facilitates fast Al 3+ desolvation. A nitrogen-functionalized porous carbon further mediates the sulfur reaction, enabling the battery with rapid-charging capability and excellent cycling stability with 85.4% capacity retention over 1400 cycles at a charging rate of 1 C. Importantly, we demonstrate that the asymmetric sulfur reaction mechanism that involves formation of polysulfide intermediates, as revealed by operando X-ray absorption spectroscopy, accounts for the high reaction kinetics at such temperature wherein the thermal management can be greatly simplified by using water as the heating media.

Stabilization of bioactive components, especially for hydrophobic functional factors, is a promising approach for improving their biological activity. Here, a metal-phenolic coordination chemistry that synthesizes biocompatible and biodegradable thin film based on tannic acid and trivalent metal ion (Fe 3+ or Al 3+ ) is addressed, and the results also demonstrate its use for encapsulating a hydrophobic drug (nobiletin) and triggering drug release for cancer treatment both in vitro and in vivo. This assembled system provides drug-loaded nanoparticles (NPs) with small, but uniform, size (≈200 nm). It displays beneficial potential in enhancing colloidal stability and preventing premature drug leakage. Moreover, the metal-phenolic coating is found to possess high cell biocompatibility as a delivery vector for controlled drug delivery, while the final fabricated drug NPs have effective anti-tumor activity by both inducing higher tumor apoptosis and inhibiting tumor metastasis, which is superior to naked drug formulations. Overall, these findings propose an effective and straightforward way for coating hydrophobic drugs employing interfacial adhesion and assembly, which can be a highly promising vehicle for controlled-release biomedical applications for cancer therapy.

Traditional hydrogel-based strain sensors do not work well under water due to extreme swelling and poor adhesion to substrates in water-rich conditions. Inspired by the jellyfish tentacles, a super stretchable dual crosslinked hydrogel was prepared as a motion sensor underwater. The hydrogel contained a cationic surfactant , hexadecyl trimethyl ammonium bromide (CTAB), that crosslinked with hydrophobic lauryl methacrylate (LMA) units in an AA-LMA copolymer . Al 3+ ions also coordinated with carboxyl groups in PAA chains and amino groups on chitosan (CS) to form ionic crosslink points. The formed hydrogel exhibited excellent anti-swelling characteristics, superior tensile properties (≈3000%), and rapid self-healing performance. Due to the complementary effects of electrostatic interactions and dynamic chemical bond formation, the hydrogel efficiently and repeatably adhered to various biological tissues, such as hogskin and shrimp, in aquatic environments. Moreover, the hydrogel-based strain sensor showed high sensitivity (GF = 2.04) over a wide sensing range from 0 to 1000% strain with high stability in air and water. The prepared materials' unique performance further expands their application prospects in flexible wearable devices , anti-counterfeiting recognition, and other fields in environmental conditions.
