Pathway decisions for reuse and recycling of retired lithium-ion batteries considering economic and environmental functions.

Reuse and recycling of retired electric vehicle (EV) batteries offer a sustainable waste management approach but face decision-making challenges. Based on the process-based life cycle assessment method, we present a strategy to optimize pathways of retired battery treatments economically and environmentally. The strategy is applied to various reuse scenarios with capacity configurations, including energy storage systems, communication base stations, and low-speed vehicles.

Collaborative and privacy-preserving retired battery sorting for profitable direct recycling via federated machine learning.

Unsorted retired batteries with varied cathode materials hinder the adoption of direct recycling due to their cathode-specific nature. The surge in retired batteries necessitates precise sorting for effective direct recycling, but challenges arise from varying operational histories, diverse manufacturers, and data privacy concerns of recycling collaborators (data owners). Here we show, from a unique dataset of 130 lithium-ion batteries spanning 5 cathode materials and 7 manufacturers, a federated machine learning approach can classify these retired batteries without relying on past operational data, safeguarding the data privacy of recycling collaborators.

Flexible Zinc-Air Batteries with Ampere-Hour Capacities and Wide-Temperature Adaptabilities.

Flexible Zn-air batteries (FZABs) have significant potentials as efficient energy storage devices for wearable electronics because of their safeties and high energy-to-cost ratios. However, their application is limited by their short cycle lives, low discharge capacities per cycle, and high charge/discharge polarizations. Accordingly, herein, a poly(sodium acrylate)-polyvinyl alcohol (PANa-PVA)-ionic liquid (IL) hydrogel (PANa-PVA-IL) is prepared using a hygroscopic IL, 1-ethyl-3-methylimidazolium chloride, as an additive for twin-chain PANa-PVA.

Species-Specific Gene Expansion of the Gene Superfamily in the Orchidaceae Family and Functional Divergence of Mannan Synthesis-Related Genes in .

Plant genes constitute a supergene family that includes the (CesA) family and nine -like (Csl) families, the members of which are widely involved in the biosynthesis of cellulose and hemicellulose. However, little is known about the superfamily in the family Orchidaceae, one of the largest families of angiosperms. In the present study, we identified and systematically analyzed the family members in three fully sequenced Orchidaceae species, i.

Freestanding and Sandwich MXene-Based Cathode with Suppressed Lithium Polysulfides Shuttle for Flexible Lithium-Sulfur Batteries.

Flexible lithium-sulfur (Li-S) batteries with high mechanical compliance and energy density are highly desired. This manuscript reported that large-area freestanding MXene (TiCT) film has been obtained through a scalable drop-casting method, significantly improving adhesion to the sulfur layer under the continuously bent. Titanium oxide anchored on holey TiCT (TiO/H-TiCT) was also produced by the well-controlled oxidation of few-layer TiCT, which greatly facilitates lithium ion transport as well as prevents the shuttling of lithium polysulfides.

Phylogenetic relationships of sucrose transporters (SUTs) in plants and genome-wide characterization of genes in Orchidaceae reveal roles in floral organ development.

Sucrose is the primary form of photosynthetically produced carbohydrates transported long distance in many plant species and substantially affects plant growth, development and physiology. Sucrose transporters (SUTs or SUCs) are a group of membrane proteins that play vital roles in mediating sucrose allocation within cells and at the whole-plant level. In this study, we investigated the relationships among SUTs in 24 representative plant species and performed an analysis of genes in three sequenced Orchidaceae species: , , and .

Stabilized Solid Electrolyte Interphase Induced by Ultrathin Boron Nitride Membranes for Safe Lithium Metal Batteries.

Lithium-ion batteries (LIBs) are still facing safety problems, mainly due to dendrite growth on the anode that leads to combustion and explosion. Forming a stable solid electrolyte interface (SEI) layer is an effective way to suppress this. To induce the formation of stable SEI using simple methods at a low cost, we report an ultrathin and large-scale hexagonal boron nitride (h-BN)/polyimide (PI) layer that was coated on a commercial polypropylene (PP) separator.

7-(Pyrazol-4-yl)-3H-imidazo[4,5-b]pyridine-based derivatives for kinase inhibition: Co-crystallisation studies with Aurora-A reveal distinct differences in the orientation of the pyrazole N1-substituent.

Introduction of a 1-benzyl-1H-pyrazol-4-yl moiety at C7 of the imidazo[4,5-b]pyridine scaffold provided 7a which inhibited a range of kinases including Aurora-A. Modification of the benzyl group in 7a, and subsequent co-crystallisation of the resulting analogues with Aurora-A indicated distinct differences in binding mode dependent upon the pyrazole N-substituent. Compounds 7a and 14d interact with the P-loop whereas 14a and 14b engage with Thr217 in the post-hinge region.

Lipid-modified polyethylenimine-mediated DNA attraction evaluated by molecular dynamics simulations.

The effect of lipid modification on polyethylenimine (PEI)-mediated DNA attraction was studied by performing umbrella sampling molecular dynamics simulations that involved PEIs modified with three different types of lipids: oleic acid (OA), linoleic acid (LA), and caprylic acid (CA). The potential of mean force between two DNA molecules in the presence of these lipid-modified PEIs was calculated using the weighted histogram analysis method, and it predicted the stability and size of the DNA aggregate. When compared to native PEI, lipid modification was found to enhance the stability of DNA aggregation in the case of long lipids (LA and OA) but reduce the stability in the case of a short lipid (CA).

Aurora isoform selectivity: design and synthesis of imidazo[4,5-b]pyridine derivatives as highly selective inhibitors of Aurora-A kinase in cells.

Aurora-A differs from Aurora-B/C at three positions in the ATP-binding pocket (L215, T217, and R220). Exploiting these differences, crystal structures of ligand-Aurora protein interactions formed the basis of a design principle for imidazo[4,5-b]pyridine-derived Aurora-A-selective inhibitors. Guided by a computational modeling approach, appropriate C7-imidazo[4,5-b]pyridine derivatization led to the discovery of highly selective inhibitors, such as compound 28c, of Aurora-A over Aurora-B.

A molecular dynamics simulation study on the effect of lipid substitution on polyethylenimine mediated siRNA complexation.

Polycations have been explored as non-viral carriers for effective delivery of small interfering RNA (siRNA). Modifying polycations such as polyethylenimine (PEI) with lipid substitution was found to improve the siRNA delivery efficiency of polycationic carriers. However, the role of such lipid modification is not clear and remains to be probed at the atomistic level.

Potential of mean force of polyethylenimine-mediated DNA attraction.

The aggregation of DNA molecules induced by cationic polymers is of importance to applications in gene delivery. In this work, we performed a series of umbrella sampling molecular dynamics simulations to calculate the potential of mean force (PMF) between two DNA molecules in the presence of polyethylenimine (PEI) molecules using the weighted histogram analysis method. The distance between the centers of mass of the two DNAs was chosen as the reaction coordinate, and the location and depth of the global minimum in the PMF curve were used to gauge the compactness and stability of the formed aggregate.
