Metallic Al is an attractive anode material in lithium-ion batteries (LIBs) owing to its relatively high theoretical capacity, low cost, and natural abundance. However, the practical application of Al-based anodes is impeded by issues such as significant volume change, low Coulombic efficiency, growth of dendrites, and sluggish lithium-ion transport during cycling. Herein, we design the inorganic–organic hybrid materials composed of poly(ethylene oxide) (PEO) and lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) with controllable morphologies and porosity to construct a 3D transport channel and gradient multisite adsorption for Li+ on the Al anode surface. Benefiting from the uniform porous structure and stronger adsorption effect of the PEO–LiTFSI, Li+ is first adsorbed onto PEO–LiTFSI, redistributing Li-ion flux. Second, the adsorbed Li+ and Li+ in LiTFSI undergo an alloying reaction with the Al anode. The two reaction processes redistribute Li-ion flux and ensure more homogeneous transport properties compared to the direct alloying reaction with Al. As a result, the NCM||Al–PEO–LiTFSI cell delivered stable cycling behavior over 500 cycles under a high 1 C cycling rate, achieving a capacity retention rate of 92.8%. The excellent rate performance was also achieved at 222.4 mA h/g at 5 C, indicating the superior practical application prospect of Al-based batteries. The proposed surface modification strategy furnishes a practicable pathway for the construction of highly stable Al anodes, thereby enabling their potential for practical applications.

The membrane fouling is a challenge for the application of ultrafiltration , one of which the cake layer is the main influencing factor. However, the pros and cons of cake layer generated in the coagulation-ultrafiltration (C-UF) process needs to be explored. This study was carried out to investigate that the effect of a cake layer on the membrane fouling behavior with three Al species coagulants for different effluents. The results indicated that the fouling mechanisms of cake layer under different effluents conditions were diverse due to the particle characteristics. The Al hydrolysis that accompanied by the interaction between Al species coagulants and the –OH/-COOH functional groups of humic acid were conducted, and the effluents of Al a presented lighter membrane fouling. Meanwhile, the components mainly trapped by the membrane were soluble microbial products, protein, polypeptides and amino acid-like materials during C-UF process, because of the decrease in the proportion of fluorescence response. For the less/compact cake layer (system 2), the average of the external and internal membrane resistances were about 25 × 10 10 m −1 and 21 × 10 10 m −1 , respectively, which caused severe membrane fouling. It was concluded that the poriferous/loose cake layer could effectively alleviate membrane fouling by re-adsorbing some organic matters.

Ag/SiO2–Al2O3 aerogel composites with different molar ratio of Si to Al were prepared by the sol–gel synthesis followed by drying under atmospheric pressure and then characterized by XRD, FT-IR, BET, SEM, XRF, TG-DTG, and Py-FTIR, respectively. The effect of doping Al on their physicochemical properties and adsorption desulfurization performance was investigated in comparison with Ag/SiO2. The incorporation of Al in Ag/SiO2 resulted in a gradual decrease in the specific surface area, an increase in the actual content of Ag, and an appearance of Brönsted acid centers. The actual content of Ag in Ag/SiO2–Al2O3-n increased first and then decreased with the increase in Al content. Doping Al in Ag/SiO2 led to an improvement in the adsorption capacity and the adsorptive selectivity for thiophene at the presence of toluene and cyclohexene, as well as the solvent washing regeneration performance, attributed to the adsorption of thiophenics on Ag/SiO2–Al2O3-n by π-complexation of Ag(I) and the acid–base interaction of Lewis and Brönsted centers with thiophenics simultaneously, and the increase in the actual content of Ag in the adsorbents. Ag/SiO2–Al2O3-100 had the largest adsorption capacity for thiophene and benzothiophene, 12.2 mg of S/gads (0.57 mmol of S/mmol of (Ag + Al)) and 17.7 mg of S/gads (0.53 mmol of S/mmol of (Ag + Al)), respectively.

There has been an increasing demand for cutting tools with excellent strength, and high wear resistance due to the gradual application of high hardness materials such as high-temperature alloys and surface thermal spray coatings. This study proposes a new design of binder for polycrystalline cubic boron nitride (PcBN) composites. The effects of Al-ZrB 2 -TiC binders on the microstructural evolution, mechanical properties, and thermal shock resistance of the PcBN composites were systematically studied. Al melting at its relatively low temperature, which enables liquid-phase sintering, enhances grain bonding, and stimulates chemical interactions among the binder constituents. These reactions lead to the formation of new phases and promote strong grain bonding, resulting in good mechanical properties. In addition, increasing sintering temperature and cBN content are found to significantly improve the mechanical properties of PcBN composites. The PcBN composites exhibit excellent bending strength of 986.55 MPa, hardness of 42.09 GPa, relative density of 97.6 %, and fracture toughness of 7.66 MPa m 1/2 , respectively. After exposure to air at 1000 °C for 30 min followed by water quenching, the residual flexural strength remained as high as 866.89 MPa, indicating good thermal shock resistance.

Zn-Al-Mg powder co-diffusion was performed on Q235 steel using a mechanical energy-assisted diffusion process. The resulting ZAM alloy diffusion coating comprised an inner Fe Zn layer composed of δ(FeZn 10 ) and Γ(Fe 11 Zn 40 ) phases, while the outer layer exhibited a multiphase structure distributed discontinuously in island-like or dot-like patterns on the δ-phase surface. The multiphase structure exhibits layered characteristics extending outward from the δ phase: an Al-rich layer composed of Al 2 O 3 and Fe Al phases; a Mg-rich layer interwoven with Mg Al phases, Mg Zn phases, and MgO; and an amorphous ZnO layer. The growth mechanism is investigated by this study, revealing that during the primary co-diffusion phase, a 20 μm Fe Zn layer formed first on the substrate. Subsequently, increased Al atoms combined with Fe atoms within the Fe Zn phase to form an Fe Al layer, thereby inhibiting Fe Zn layer growth. Finally, active Mg atoms form a Mg-rich layer on the surface of the Fe Al layer. Mg-rich layer combines with Al atoms to form a Mg Al phase and induces lattice distortion, thereby inhibiting Fe Al layer growth. Throughout the process, the removal of HCl exposes the Fe Zn layer and restores its normal growth. Eventually, under this dynamic mechanism, a complex, multi-phase outer structure is formed. The self-corrosion current (J corr ) of the ZAM diffusion coating (1.673 × 10 −5 A/cm 2 ) markedly lower than the ZA diffusion coating (5.499 × 10 −5 A/cm 2 ). While the ZAM diffusion coating exhibited a weight gain of 1.182 ± 0.075 mg/cm 2 after 120 h of oxidation at 500 °C, which was slightly higher than the ZA diffusion coating but considerably lower than Q235 steel.

Exploring CO 2 adsorption under humid conditions is crucial for practical applications. Herein, ZJU-521(Al) was synthesized using low-toxicity helical secondary building units (SBUs, [Al 5 (OH) 7 (−COO) 8 ] ∞ ) and tetrakis (4-carboxyphenyl)methane (H 4 MTTB) ligand, with excellent chemical stability. Saturated CO 2 adsorption capacities of ZJU-521(Al) reach 6.19 mmol/g at 273 K and 4.52 mmol/g at 298 K, respectively, and moderate isosteric heat of 28.23 kJ/mol, enabling low-energy regeneration. Simulation results reveal two CO 2 adsorption sites on ZJU-521(Al): site I, located near the helical SBUs and interwoven with the helical SBUs, and site II, situated near the H 4 MTTB ligand. ZJU-521(Al) can effectively separate CO 2 from the CO 2 /N 2 mixture, as identified by the ideal adsorbed solution theory values of 28.81 at 273 K and 40.83 at 298 K for CO 2 /N 2 (15/85) mixture, respectively. Dynamic adsorption experiments reveal dynamic CO 2 adsorption of 0.59 mmol/g under dry conditions and 0.54 mmol/g at 80% relative humidity (RH) for ZJU-521(Al), highlighting its moisture-resistant behavior for CO 2 adsorption under humid conditions. Most adsorbed CO 2 is readily desorbed by argon purging at 14 min (dry) and 12 min (80% RH) at 298 K, respectively. Therefore, ZJU-521(Al) emerges as a promising candidate for efficient CO 2 adsorption, separation, and desorption even under humid conditions.

In this paper, a solvent/non-solvent synthetic approach has been utilized in preparing a new nanoenergetic material KClO 4 @Al/CuO by coating Al/CuO nanocomposites particles with a layer of nanoscale oxidizer KClO 4 . The coating process and mechanism are discussed. The composites of Al/CuO are uniformly mixed by mechanical ball milling process and CuO acts as a catalytic metallic oxide. The ternary mixtures KClO 4 @Al/CuO were characterized by X-ray diffraction (XRD) and the results reveal that after ball-milling and chemical synthesis process, the phase compositions haven’t changed. Scan electron microscopy (SEM) images show that these energetic nanocomposites consist of small clusters of Al/CuO that are in intimate contact with a continuous and clear-cut KClO 4 layer (100–400 nm). In a Scanning transmission electron microscopy (STEM) elemental map, high K/Cl intensity on the perimeter of the nanoparticles and high Cu/Al content in the interior powerfully demonstrated the KClO 4 @Al/CuO core-shell nanostructure. Electrical ignition experiments and pressure cell test prove that these nanoenergetic composites are more sensitive to ignition with much higher burning rate than traditional formulations (conventional counterparts). To quantify the enhancement of thermal behavior, Thermogravimetry (TG) and Differential scanning calorimetry (DSC) were performed and the results show that the burning rate of these energetic nanocomposites nearly tripled.

The core/shell nano-TiN-coated Al powders (TiN/Al) were prepared and added into A356 alloy by ultrasonic-assisted casting method in this work. The results show that TiN/Al has a better dispersion in A356 matrix and a stronger strengthening effect than TiN without the core/shell structure. With the addition of TiN/Al, most of the coarse primary α-Al dendrites of A356 turn into equiaxial. After T6 heat treatment, it is found that eutectic silicon in A356 with TiN/Al becomes columnar or globular in shape and smaller in size, which causes a greatly enhanced elongation of 11.7%. The results also suggest that the addition of nanoparticles can affect the precipitation behaviors and change the shapes and sizes of the precipitation.

Direct hydrogenation of CO 2 into ethanol has been considered as an up-and-coming way to achieve CO 2 utilization. Ethanol can be generated by reverse water gas shift as well as CO hydrogenation over Co-based catalysts, where the regulation of Co 0 − Co δ+ is critical. Herein, we designed a supported Co-based catalyst doped with gallium, which was derived from Co-Al-O spinel precursor to facilitate synergistic catalyzing for CO 2 -to-ethanol transformation. The selectivity of ethanol reached 20.1 % in a continuous flow fixed micro-reactor over reduced CoGa 1.0 Al 1.0 O 4 /SiO 2 catalyst at 270 °C and 3.0 MPa. Results of characterization show that the existence of the strong interaction between Ga oxide and cobalt induced the configuration of Co 0 − Co δ+ active pairs, which promotes the process of ethanol synthesis by coupling the dissociation (CH x *)/non-dissociation (CO*) of the intermediates. The strategy by tuning the interaction between cobalt and gallium and/or aluminum oxide brings an avenue to tailor Co 0 − Co δ+ active pairs for the hydrogenation of CO and CO 2 .

The preparation of the high cis −1,4-polyisoprene by Ziegler-Natta catalysis system was studied. The effect of Al-Ti catalysts modified by ethers with different structures which are different electron donor reagent on polymerization of isoprene has been mainly investigated. By the measurement method of the monomer conversion, FTIR, and 1 H NMR spectroscopy, the influence of, respectively, added diphenyl ether, anisole, dibutyl ether, or methyl tert -butyl methyl ether as a third active component on the heterogeneous TiCl 4 -Al( i -Bu) 3 -ether catalyst activity and microstructure of synthetic polyisoprene was analyzed. By the adding of diphenyl ether or dibutyl ether, the process of prefabricated heterogeneous catalyst is quickly and catalyst particle quantity is large. The polymerization conversion is high and the microstructure cis −1,4 content of the resulting polymer can reach 92%. But Al( i -Bu) 3 added anisole or methyl tert -butyl methyl ether hard to cooperate with TiCl 4 . © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016 , 133 , 44357.

NO 2 is a potent air pollutant because of its deleterious effects on human beings and other organisms. The state-of-the-art catalysis-based deNO x techniques (e.g., selective catalytic/non-catalytic reduction) are incapable of ambient NO 2 abatement due to their low efficiency at temperatures below 300 °C. It is thus conceivable to directly capture NO 2 from the atmosphere by selective adsorption on porous materials. This work reports the rational development and demonstration of the Mg–Al layered double hydroxides (LDHs) and their derived mixed metal oxides (MMO), using environmentally benign solvents , as high-capacity adsorbents for ambient NO 2 abatement. By boosting the densities of accessible basic sites using layer delamination strategies, the highest NO 2 adsorption capacity of 8.52 mmol/g was achieved by the delaminated LDH material (LDH-AM), which was substantially higher than other popular and robust adsorbents, such as zeolites (0.36–3 mmol/g) and carbon-based adsorbents (2–6 mmol/g). Using Fourier transform infrared spectroscopy and powder X-ray diffraction, it was revealed that NO 2 adsorption occurs on the surface M-OH basic sites and within the layers by simultaneously replacing the interlayer CO 3 2− ions of LDH. This work affords not only promising, durable, and scalable adsorbents for ambient NO 2 removal but also a strategy to develop adsorbents with high density of basic sites for capture of other pollutant acid gases from the environment.

Herein, fluorine fixation, nitrogen removal, and the alkaline solution recovery of alumina were studied using calcium-based high-temperature soda roasting. In addition, the effects of roasting conditions, dissolution conditions, and additives (carbon alkali and calcium salt) on fluorine fixation and alumina recovery were studied. The results show that when the roasting temperature was 1100 ℃ and the roasting time was 2 h, the dissolution temperature was 80 °C, while the dissolution time was 20 min. The ratio of soda to dross was 1.0, and 30 wt% CaCO 3 had been added as a fluorine fixing agent. The Al extraction rate from aluminum dross (AD) reached 86.21%, the denitrification rate reached 99.54%, the concentration of soluble fluoride ion was reduced to 0.111 g·L −1 , and the fluoride fixation rate was 75.04 wt%. CaF 2 is the main component of the leaching residue, which can be added as an insulation material for electrolysis. Alkaline oxidation roasting and calcium-based fluoride fixation are effective methods to separate aluminum, fluoride, and nitrogen. This study provides a new method for the safe and efficient utilization of AD.
