Here we investigate the steady-state dynamic processes of the double-cavity system and the transmission of optical waves from opposite cavity directions. The transmission spectrum of the probe field is presented in detail and the physical mechanism of the induced transparency window is analyzed.

Comparative transcriptome and metabolome analysis reveals the differential response to salinity stress of two genotypes brewing sorghum.

Salinity tolerance in brewing sorghum is a very important trait, especially in areas that are affected by soil salinity. In order to elucidate the mechanism underlying salt tolerance, we conducted a comparative analysis of the transcriptome and metabolome in two distinct sweet sorghum genotypes, namely the salt-tolerant line NY1298 and the salt-sensitive line MY1176, following exposure to salt treatment. Our initial findings indicate the presence of genotype-specific responses in brewing sorghum under salt stress conditions.

High-density lipoprotein nanoparticles spontaneously target to damaged renal tubules and alleviate renal fibrosis by remodeling the fibrotic niches.

Chronic kidney disease (CKD) ultimately causes renal fibrosis and end-stage renal disease, thus seriously threatens human health. However, current medications for CKD and fibrosis are inefficient, which is often due to poor targeting capability to renal tubule. In this study, we discover that biomimetic high-density lipoprotein (bHDL) lipid nanoparticles possess excellent targeting ability to injured tubular epithelial cells by kidney injury molecule-1(KIM-1) mediated internalization.

Data-driven exploration of weak coordination microenvironment in solid-state electrolyte for safe and energy-dense batteries.

The unsatisfactory ionic conductivity of solid polymer electrolytes hinders their practical use as substitutes for liquid electrolytes to address safety concerns. Although various plasticizers have been introduced to improve lithium-ion conduction kinetics, the lack of microenvironment understanding impedes the rational design of high-performance polymer electrolytes. Here, we design a class of Hofmann complexes that offer continuous two-dimensional lithium-ion conduction channels with functional ligands, creating highly conductive electrolytes.

Structural Basis of Ultralow Capacitances at Metal-Nonaqueous Solution Interfaces.

Metal-nonaqueous solution interfaces, a key to many electrochemical technologies, including lithium metal batteries, are much less understood than their aqueous counterparts. Herein, on several metal-nonaqueous solution interfaces, we observe capacitances that are 2 orders of magnitude lower than the usual double-layer capacitance. Combining electrochemical impedance spectroscopy, atomic force microscopy, and physical modeling, we ascribe the ultralow capacitance to an interfacial layer of 10-100 nm above the metal surface.

Nano LiF-Enabled In Situ Synergistic Catalytic Polymeric Electrolytes for Stable Lithium Metal Batteries.

Solid polymer electrolytes (SPEs) with excellent ionic conductivity and a wide electrochemical stability window are critical for high-energy lithium metal batteries (LMBs). However, the widespread application of polymer electrolytes is severely limited by inadequate room-temperature ionic conductivity, sluggish interfacial charge transport, and uncontrolled reactions at the electrode/electrolyte interface. Herein, we present a uniform polymerized 1,3-dioxolane (PDOL) composite solid polymer electrolyte (PDOL-S/F-nano LiF CSE) that satisfies these requirements through the in situ catalytic polymerization effect of nano LiF on the polymerization of 1,3-dioxolane-based electrolytes.

Rational Design of Nanozymes for Engineered Cascade Catalytic Cancer Therapy.

Nanozymes have shown significant potential in cancer catalytic therapy by strategically catalyzing tumor-associated substances and metabolites into toxic reactive oxygen species (ROS) , thereby inducing oxidative stress and promoting cancer cell death. However, within the complex tumor microenvironment (TME), the rational design of nanozymes and factors like activity, reaction substrates, and the TME itself significantly influence the efficiency of ROS generation. To address these limitations, recent research has focused on exploring the factors that affect activity and developing nanozyme-based cascade catalytic systems, which can trigger two or more cascade catalytic processes within tumors, thereby producing more therapeutic substances and achieving efficient and stable cancer therapy with minimal side effects.

Highly Optimized CNS Penetrant Inhibitors of EGFR Exon20 Insertion Mutations.

Despite recent advances in the inhibition of EGFR (epidermal growth factor receptor), there remains a clinical need for new EGFR Exon20 insertion (Ex20Ins) inhibitors that spare EGFR WT.
