Article Abstract
Solid-state lithium metal batteries with a Li-rich manganese oxide (LRMO) cathode suffer from challenges in interfacial compatibility. This study improves the interface between a PVC-based gel electrolyte and electrodes dual-component modulation. The optimized electrolyte exhibits high oxidation stability and facilitates the formation of inorganic-rich interphases, contributing to the long-term stability of the interface. Therefore, the 4.6 V Li|LRMO cells operate stably for 100 cycles at 0.2C, delivering an initial capacity of 215.2 mA h g and average coulombic efficiency of 99.55%.

The treatment of chronic diabetic wounds faces considerable challenges owing to complex environments in the wound bed, such as chronic inflammation, excessive reactive oxygen species (ROS), impaired extracellular matrix (ECM) and bacterial infection. Current strategies, including bandages, hydrogel dressings and medical devices, that focus solely on a few pathological features have limited success. Herein, a fast self-gelling polyacrylic acid (PAA) derivative/madecassoside (MA) particulate dressing with anti-inflammatory, antioxidative, collagen deposition-promoting and intrinsic antibacterial properties is developed to simultaneously regulate the wound microenvironment and promote tissue regeneration in infected diabetic wounds.

The increasing density and complexity of electromagnetic signals have brought new challenges to multi-component radar signal recognition. To address the problem of low recognition accuracy under low signal-to-noise ratios (SNR) in adapting the common recognition framework of combining time-frequency transformations (TFTs) with convolutional neural networks (CNNs), this paper proposes a new dual-component radar signal recognition framework (TFGM-RMNet) that combines a deep time-frequency generation module with a Transformer-based residual network. First, the received noisy signal is preprocessed.

One of the goals of synthetic biology is to enable the design of arbitrary molecular circuits with programmable inputs and outputs. Such circuits bridge the properties of electronic and natural circuits, processing information in a predictable manner within living cells. Genome editing is a potentially powerful component of synthetic molecular circuits, whether for modulating the expression of a target gene or for stably recording information to genomic DNA.

The development of injectable, dual-component formulations based on natural-based polysaccharides is a promising strategy for the localized treatment of rheumatoid arthritis (RA). In the present study, biomimetic formulations consisting of aldehyde-functionalized hyaluronic acid (AHA) and O-carboxymethyl chitosan (OCC) were developed, presenting rapid in situ gelation rates and finely tunable physicochemical properties. These two properties allowed for the controlled delivery of anti-inflammatory, antioxidant, and pro-regenerative agents (i.
