chemical Communications 2025年第43期61卷 7770-7794页

作者： Sawangphruk, Montree Centre of Excellence for Energy Storage Technology Department of Chemical and Biomolecular Engineering School of Energy Science and Engineering Vidyasirimedhi Institute of Science and Technology Rayong21210 Thailand

This review explores recent advances in lithium-sulfur (Li-S) batteries, promising next-generation energy storage devices known for their exceptionally high theoretical energy density (∼2500 W h kg−1), cost-effectiveness, and environmental advantages. Despite their potential, commercialization remains limited by key challenges such as the polysulfide shuttle effect, sulfur's insulating nature, lithium metal anode instability, and thermal safety concerns. This review provides a comprehensive and forward-looking perspective on emerging material strategies—focusing on cathode, electrolyte, and anode engineering—to overcome these barriers. Special emphasis is placed on advanced sulfur-carbon composites, including three-dimensional graphene frameworks, metal-organic frameworks (MOFs), covalent organic frameworks (COFs), and MXene-based materials, which have demonstrated significant improvements in sulfur utilization, redox kinetics, and cycling stability. Innovations in electrolytes—particularly solid-state and gel polymer systems—are discussed for their roles in suppressing polysulfide dissolution and enhancing safety. This review also examines lithium metal anode protection strategies, such as use of artificial SEI layers and 3D lithium scaffolds and lithium alloying. Finally, it discusses critical issues related to large-scale manufacturing, safety, and commercial scalability. With ongoing innovation in multifunctional materials and electrode design, Li-S batteries are well positioned to transform energy storage for electric vehicles, portable electronics, and grid-scale systems. © 2025 The Royal Society of Chemistry.

This study synthesizes three sequential steps: pretreatment, acid hydrolysis, and enzyme hydrolysis for bioethanol and hydrochar production from macroalga Gracilaria. The Taguchi method is employed separately in each step to optimize relevant operating factors, aiming to maximize the monosaccharide yield. During pretreatment, environmentally friendly alkaline ionized water is utilized as it does not contain chemical additives. Afterward, microwave-assisted hydrolysis is adopted to enhance the monosaccharide yield of the macroalga for bioenergy production. The results show that the total sugar of Gracilaria undergoing acid hydrolysis alone is 28.72 g‧L−1. The total sugar content after alkaline pretreatment followed by acid hydrolysis is 32.64 g‧L−1, and it increases to 34.76 g‧L−1 after adding enzymes. Meanwhile, the higher heating value of Gracilaria increases from 10.884 MJ‧kg−1 to 12.620 MJ‧kg−1 after undergoing alkaline pretreatment. After the acid and enzyme hydrolysis processes, it increases to 15.164 MJ‧kg−1. The solid biofuel's calorific value increases by 39 % from the three-stage processes. The liquid product combined with Saccharomyces cerevisiae can produce bioethanol, while the produced hydrochar can be used as a solid fuel. This research promotes the development of macroalgal biomass for energy and environmental applications, thereby advancing the circular bioeconomy. © 2024 The Institution of chemical Engineers

Mechanics-modified equilibrium potential for linear-elastic electrode materials

EES Batteries 2025年第3期1卷 450-467页

作者： Taeho Jung Yueming Song Gianna M. Valentino Paul Albertus Department of Chemical and Biomolecular Engineering University of Maryland College Park Maryland USA Department of Materials Science and Engineering University of Maryland College Park Maryland USA

There is inconsistency in how the mechanics-modified equilibrium potential is constructed in the literature for solid-state batteries; both hydrostatic and surface-normal stresses have been employed. We attempt to resolve this by deriving equilibrium-potential expressions for a linear-elastic electrode material deposited on a solid electrolyte under three different loading conditions: (1) working electrode under out-of-plane uniaxial compression, (2) solid electrolyte under in-plane uniaxial compression, and (3) solid electrolyte under pure shear. Our analysis, which starts from full tensorial stress and strain descriptions specifically at the isothermal electrode/electrolyte interface, indicates that the hydrostatic stress is a more general and widely applicable choice. The deviatoric contribution that the full tensor treatment considers is shown to be practically negligible, making the hydrostatic stress an excellent approximation for battery-modeling purposes. Furthermore, our analytical expressions depend on the mechanical properties of the constituent electrode and electrolyte (i.e., their elastic moduli and Poisson's ratios); no such explicit dependence has been fleshed out previously for experimentally relevant systems. COMSOL simulation results are provided to verify the validity of the analytical expressions, and correction factors are introduced to extend their use to more practical systems. Finally, a cantilever-beam experiment is suggested to help validate our proposed use of the hydrostatic stress more explicitly.

Household bleach products as high-performance and cost-effective cleaning agents for membrane fouling

引用

South African Journal of chemical engineering 2023年 46卷 35-41页

It has been widely known that polymeric membrane such as polyvinylidene fluoride (PVDF) is very prone to fouling that occurs during the filtration process. In the same light, membrane cleaning has also been popularly used as a mean to remove foulants which accumulated on or inside the membrane. In this paper, the utilization of domestic bleach, which is affordable and easily found in the nearest markets, as the membrane cleaning agent is discussed. The performance evaluation is conducted on three kinds of commercial domestic bleaches, namely Bayclin, Proclin, and Soclin. In order to study deeper about those product potentials, the performance is compared with the pure sodium hypochloride (NaOCl) which has been known as a common chemical cleaning agent, and distillate water. The results show that the bleach products work excellence in cleaning the fouled membrane which confirmed by the scanning electron microscopy (SEM) analysis results, in which membranes cleaned with the bleaches have cleaner surface compared to that cleaned with distillate water. Interestingly, the positive outcome can also be seen in the flux recovery ratio (FRR) of the membranes after cleaning which managed to recover up to 95% of the lost flux. Overall, all three bleach products showed closely similar performance as the original NaOCl, and showed far better performance than distillate water. This result emphasizes that the domestic bleaches are highly promising to be membrane chemical cleaning agents, replacing the common chemicals. This work makes a significant contribution toward giving reasonably priced options for alternative methods of cleaning membranes. © 2023 The Author(s)

作者： Bellaver, Emyr Hiago Militão da Costa, Ingrid Redin, Eduarda Eliza Moroni, Liziane Schittler Kempka, Aniela Pinto Santa Catarina State University Department of Animal Production and Food Science Multicentric Graduate Program in Biochemistry and Molecular Biology SC Lages Brazil Santa Catarina State University Department of Food Engineering and Chemical Engineering SC Pinhalzinho Brazil

The increasing quest for therapeutic alternatives in treating non-communicable chronic diseases like obesity has propelled research into bioactive peptides, with a particular focus on milk due to its rich protein composition and associated health benefits. Milk fermentation, a traditional process in dairy production, enhances the bioactivity of peptides, broadening their potential therapeutic uses. This study investigated the anti-obesity potential of peptides from bovine milk fermented by Lacticaseibacillus casei LBC 237, identifying 143 peptides, notably LGPV and EVPMP. In silico analyses revealed that LGPV and EVPMP biopeptides exhibited significant interactions with target proteins, employing various molecular interactions such as Van der Waals forces, hydrogen bonds, and electrostatic interactions. These peptides shared common binding sites in some enzymes, suggesting a similar mode of interaction between molecule and target protein, akin to key pharmaceuticals recommended for treating these pathologies. Furthermore, amino acid characteristics present in the peptides, including hydrophobic residues like Leucine, Glutamate, Valine, and Proline, proved essential for their bioactive and inhibitory activities. These findings highlight the potential of LGPV and EVPMP biopeptides as therapeutic agents in managing obesity and metabolic disorders. They provide important insights into their mechanisms of action, paving the way for future research to apply them practically in preventing and treating metabolic conditions. © 2024 The Authors
