Herein, a multifunctional leucine additive is introduced into ZnSO4 electrolyte to create adaptable interfaces. The polar groups make leucine preferentially adsorb on Zn metal surface, inducing Zn2+ uniform deposition to suppress Zn dendrites growth, while the hydrophobic groups prevent Zn metal contacting from water, inhibiting water-related side reactions. Meanwhile, the zwitterionic amino and carboxyl segments can dynamically adjust the pH changes with a stable interfacial microenvironment, thereby inhibiting side reactions. Besides, the high affinity of leucine to Zn2+ regulated the solvated structure and facilitated forming inorganic ZnS layer on Zn metal, reducing the Zn-ions desolvation energy barrier and enhancing Zn-ions plating kinetics. As a proof of concept, the symmetric cells with leucine additives exhibit an extended cycling lifetime of 2700 h at 1.0 mA cm−2/1.0 mAh cm−2 when compared to bare ZnSO4 electrolyte (200 h).

This research focused on addressing the limitations of conventional cathode materials while examining the intercalation behaviour of ammonium ions within the GeOx@Ti3C2Tx framework.

This approach enhanced the structural stability, increased the specific surface area, and improved ion transport properties. The postmortem ex-situ XRD, XPS and TEM investigations show that GeOx@Ti3C2Tx maintained its structural integrity and electrochemical stability during the charge/discharge process. The assembled GeOx@Ti3C2Tx//AC-AHSC device exhibits high specific capacitance, excellent rate capability, and remarkable cycling stability. The device exhibits a high energy density of 51.4 Wh/kg at a power density of 800.6 W/kg, which is superior to many existing MXene-based devices.

However, it remains a challenge to convert peel wastes into bioplastics without decomposing their biocomponents. Furthermore, most of the bioplastics currently being researched have poor performance, especially in terms of trade-offing high strength, toughness, and good processability. Here, we utilize a noncovalent-mediated design to convert peel waste into pectocellulosic bioplastic that features the in situ ordered self-assembly of cellulose and pectin in the peel into a structure similar to a carboxylic acid dimer via hydrogen bonding. Benefiting from efficient energy dissipation mechanisms and reversible hydrogen bonding interactions, pectocellulosic bioplastics exhibit excellent mechanical properties (superior to most petrochemical-based and bio-based plastic materials), and can be molded into 2D/3D shapes or reprocessed into new plastics, realizing a combination of high strength (50.5 MPa), toughness (5.1 MJ/m3) and good processability. These bioplastics also combine biosafety (48 h cell viability > 85 %), biodegradability, and durability. Based on these characteristics, these pectocellulosic bioplastics can be considered as a candidate for petrochemical plastics, particularly suitable for some sensitive applications such as food inner packaging. Excitingly, the universality of this strategy in a variety of peel wastes has been verified. This work highlights the transformative potential of converting peel waste into valuable materials, providing a sustainable solution to plastic pollution and organic waste management.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"114 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2024-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142840837","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

But they always suffer from severe deterioration in energy storage performance at high temperatures because of accelerated carrier transfer and thermal runaway. Incorporating ceramic fillers into polymer is one of the most promising strategies to suppress the high-temperature carrier transfer. However, poor compatibility between ceramic and polymer always leads to agglomeration. Herein, SiO2 microspheres and Au nanoparticles are homogeneously embedded into the polymer films, forming a unique nanocomposite with a hilly-like SiO2/Au nanolayer. Benefiting from the wide bandgap of SiO2 microspheres and Coulomb-blockade effect of Au nanoparticles, the high-temperature charge transport is effectively suppressed. As a result, the poly(vinylidene fluoride-hexafluoropropylene) film embedded with a hilly-like SiO2/Au nanolayer exhibits significant enhancements of 252 %, 145 %, and 220 % at 50 ℃, 80 ℃, and 100 ℃ in energy density. It is further demonstrated that, the SiO2/Au nanolayer can also be employed to enhance the high-temperature energy performances of polyetherimide. The SiO2/Au/polyetherimide composite film achieves a high discharged energy density (6.16 J cm−3) for the η of 80 % at 600 MV m−1 and 150 ℃. This work offers an innovative and effective strategy to address the long-standing filler agglomeration challenge in organic/inorganic nanocomposites, which is not only of great significance for polymer based dielectric composites, but is also illuminating for the design of other nanocomposites.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"7 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2024-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142840845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the polar thionyl groups in sulfone lead to continuous reaction with lithium (Li) metal, and high viscosity of sulfone could decrease its Li+ ionic conductivity, which obstructs further application of SL in Li metal batteries (LMBs). Herein, the methylenebisacrylamide (MBA) crosslinked SL, fluorinated ethylene carbonate (FEC) based quasi-solid-state electrolyte (MSFE) was designed to address above problems. By introducing FEC to passivate metallic Li and 1H,1H,5H-octafluoropentyl-1,1,2,2-tetrafluoroethyl ether (OTE) as diluent to decrease viscosity of electrolyte, MSFE exhibits a high ionic conductivity of 1.77 × 10−3 S cm−1 and wide electrochemical stability window up to 5.6 V. Therefore, LiCoO2/MSFE/Li (LCO/MSFE/Li) batteries show a high capacity retention of 95.7 % after 100 cycles under 0.2C. Moreover, formation mechanism and kinetic evolution of the hybrid EEI is revealed via density functional theory (DFT) calculations and in-situ galvanostatic electrochemical impendence spectra (IS-GEIS) coupled with distribution relax time (DRT) technology.

However, developing HNBR that combines high hydrogenation, excellent solvent resistance, and superior low-temperature performance remains a challenge. This study introduces a novel two-step process of “graft modification and catalytic hydrogenation” to enhance nitrile rubber (NBR) emulsions. Hydroxyethyl Acrylate (HEA) flexible monomer was grafted onto the rubber molecular chain, and the introduced ester group and hydroxyl group (–OH) enhanced the compatibility and low temperature resistance (−20 °C) of the latex system. We achieved hydrogenation rates of up to 99 % by precisely controlling intermediate formation during catalytic hydrogenation. This approach synergistically enhances the mechanical and solvent resistance of HNBR by combining hydrogen bonding from grafting and covalent cross-linking from hydrogenation. The resulting HNBR-HEA achieves a tensile strength of 7.2 MPa, which is 550 % higher than that of unmodified NBR, and the swelling resistance in toluene is reduced to 207 % with a high crosslinking density of 92.07 × 10−3 mol/cm3. Additionally, when blended with polyaniline (PANI), HNBR-HEA exhibited impressive mechanical strength (3.3 MPa) and high electrical conductivity (0.97 S m−1), making it suitable for electroluminescent devices, wearable sensors, and Morse code-based emotional expression systems.
