During embryonic development, both corneal epithelial cells (CECs) and keratinocytes (KCs) originate from the surface ectoderm. As a result of this shared origin, corneal epithelial cells may exhibit the same characteristics as the skin epidermis in pathological situations, while keratinocytes are ideal seed cells for tissue-engineered corneas. However, how the identities of keratinocytes and corneal epithelial cells are determined is currently unclear.

Complex diseases may not always progress in a gradual manner. In the early stages of complex diseases, obvious symptoms are usually not observable, but there is a commonality: there is a brief state of predisease between the progression from normal state to disease state, which usually includes three stages: normal state, critical state of predisease, and disease state. Identifying this critical state, especially with a single sample from an individual, remains a difficult task.

Accurately predicting the efficiency of surfactant-enhanced recovery of non-aqueous phase liquid (NAPL) using non-ionic surfactants requires a precise estimation of the kinetics of rate-limited solubilization under the effect of bulk partition. This study investigated the kinetics of surfactant partition from aqueous phase into liquid NAPL and its subsequent impact on the solubilization kinetics of dodecane. For all surfactants examined, the solubilization of dodecane by anionic rhamnolipid (RL) and SDBS, presenting NAPL-water interface adsorption loss only, closely followed the first-order mass transfer model under the assumption of constant solubility.

Plexciton Photoluminescence in Strongly Coupled 2D Semiconductor-Plasmonic Nanocavity Hybrid.

ACS Nano

February 2025

Key Laboratory of Artificial Micro- and Nano-structures of Ministry of Education, School of Physics and Technology, Wuhan University, Wuhan 430072, China.

Strong plasmon-exciton interaction between two-dimensional transition metal dichalcogenides and a plasmonic nanocavity under ambient conditions has been reported extensively. But the suspicion on whether it has reached a true "strong coupling" is always there because the commonly used dark-field scattering spectroscopy shows a larger spectral splitting and the splitting in the photoluminescence spectra is absent. Here, by using a nanobipyramid-over-mirror to enhance the in-plane vacuum field, we achieve spectral Rabi splitting in both scattering and differential reflection spectra and observe a clear photoluminescence emission of the lower plexciton branch.

Ternary heterojunction BiS/MoS/BiMoO was designed as a signal probe to develop a dual signal amplification strategy empowered electrochemical biosensor for sensitive miRNA-21 detection by combining with catalytic hairpin assembly (CHA). The combination of the BiS/MoS/BiMoO heterojunction as a tracer indication probe and the CHA amplification strategy not only took fully use of the highly dense nanowire interwoven structure and superior active region of the probe, but also endowed the ability to improve the molecular hybridization efficiency by collision, which significantly avoided the cumbersome chain design and greatly simplified the step-by-step construction of the electrode surface. Hairpin H1 was first added dropwise to the gold nanoparticle-decorated electrode surface, and then opened by the introduced miRNA-21 to initiate the specific hybridization.

Impact of Varying Velocities and Solvation Boxes on Alchemical Free-Energy Simulations.

J Chem Inf Model

Department of Computational Chemistry, Lund University, Chemical Centre, P.O. Box 124, Lund SE-221 00, Sweden.

Alchemical free-energy perturbation (FEP) is an accurate and thermodynamically stringent way to estimate relative energies for the binding of small ligands to biological macromolecules. It has repeatedly been pointed out that a single simulation normally stays near the starting point in phase space and therefore underestimates the uncertainty of the results. Therefore, it is better to run an ensemble of independent simulations.

Shanghai-Hong Kong Joint Laboratory in Chemical Synthesis, Shanghai Institute of Organic Chemistry, University of Chinese Academy of Sciences, Chinese Academy of Sciences Shanghai 200032 China

An efficient Pd-catalyzed regioselective intramolecular aerobic oxidative dehydrocoupling of BH/CH between -carborane and arenes has been achieved with the construction of a series of five-, six- and seven-membered rings under mild reaction conditions. Control experiments indicate that B-H activation proceeds preferentially over the aryl C-H. These new polyarene-carborane conjugates have potential applications in materials as demonstrated by pyrene fused -carborane that exhibits unique dual-phase emission, intramolecular charge transfer (ICT), and aggregation-induced emission (AIE) properties.

A Reliable High-Performance Floating-Gate Transistor Based on ZrS Native Oxidation for Optoelectronic Synergistic Artificial Synapses.

ACS Appl Mater Interfaces

February 2025

Henan Key Laboratory of Infrared Materials & Spectrum Measures and Applications, School of Physics, Henan Normal University, Xinxiang 453007, China.

Floating-gate transistors (FGTs), considered the most promising structure among three-terminal van der Waals (vdW) synaptic transistors, possess superiorities in improved data retention, excellent endurance properties, and multibit storage capacity, thereby overcoming the von Neumann bottleneck in conventional computing architectures. However, the dielectric layer in FGT devices typically depends on atomic layer deposition or mechanically transferred insulators, posing several challenges in terms of device compatibility, manufacturing complexity, and performance degradation. Therefore, it is crucial to discover dielectrics compatible with two-dimensional (2D) materials for further simplifying FGT structures and achieving optimal performance.

Transition-metal-catalyzed enantioselective C-H activation has transformed the landscape of asymmetric synthesis, enabling the efficient conversion of C-H bonds into C-C and carbon-heteroatom (C-X) bonds. However, the formation of C-S bonds through enantioselective C-H thiolation remains underdeveloped due to challenges such as catalyst deactivation and competitive coordination of sulfur-containing compounds with chiral ligands. Herein, we report an unprecedented approach to constructing sulfur-substituted planar chiral ferrocenes (PCFs) through copper-mediated enantioselective C-H thiolation enabled by only a 2.
