PEDOT:PSS-Based OECT Common-Source Amplifiers for Electrophysiological Signal Amplification

Stable amplification of weak electrophysiological signals is important for low-voltage bioelectronic interfaces, but the gain and waveform fidelity of organic electrochemical transistor (OECT)-based amplifiers are strongly influenced by device characteristics and bias conditions....

Interfacial Molecular Behavior and Organization of Low-Fluorine Surfactants at the sc-CO2/Water Interface

Understanding the molecular organization of surfactants at the sc-CO2/water interface is essential for the rational design of CO2-philic interfacial formulations with reduced fluorine content. In this work, three low-fluorinated anionic surfactants (LF1–LF3) with different hydrop...

Compatibility of Low‐Dimensional Perovskites in n–i–p and p–i–n Perovskite Solar Cells

ABSTRACT Low‐dimensional (LD) perovskites have emerged as a cornerstone strategy for mitigating the intrinsic instability and suppressing interfacial non‐radiative recombination in 3D perovskites. Nevertheless, the intrinsic charge transport anisotropy of LD phases fundamentally...

NoiBic: a noise-tolerant biclustering algorithm for high-throughput gene expression data analysis

Abstract Motivation High-throughput transcriptomic technologies generate large-scale gene expression datasets for functional module discovery. However, technical and biological noise can obscure coherent expression patterns and compromise module detection. Noise-tolerant methods...

Mitigating urban tunneling risks: Detecting adverse geology with a tunnel-surface-borehole observation system using TBM drilling noise source

Accurately forecasting adverse geological conditions ahead of the tunnel face is a critical challenge for the safety and efficiency of mechanized urban tunneling. Unforeseen features such as faults and karst cavities often pose significant geohazards, including collapse, ground d...

Functional Inequalities and Random Walks on Increasing Subsets of the Hypercube

Abstract. Motivated by random walks on subsets of the hypercube, we prove two discrete functional inequalities on the hypercube by the technique of induction-by-restrictions. First, we give a short, elementary proof of the Poincaré inequality on increasing subsets of the cube rec...

Rheological characterization and microstructural features of a novel polymer-modified bentonite slurry for underground construction

During underground construction, complex conditions often degraded slurry rheological performance and compromised stability. A polymer-modified bentonite slurry was developed in this study using a novel composite polymer additive prepared by combining polyethylene oxide (PEO) and...

Radiation-induced damage and static dielectric constant changes in AlGaN from multi-method simulations

This work presents a multiscale simulation study of irradiation induced amorphization and dielectric degradation in AlGaN alloys. Proton and alpha particle irradiation in Al x Ga 1-x N with different Al contents was first analyzed by Monte Carlo simulations to determine penetrati...

Vibration-Based Fault Diagnosis of Power-Transformer On-Load Tap Changers Using SGMD and CMPA-SMAGNet

Fault diagnosis of power-transformer on-load tap changers (OLTCs) is difficult because their vibration signals are nonlinear and nonstationary. This study evaluates CMPA-SMAGNet, a diagnostic framework that combines symplectic geometry mode decomposition (SGMD), a dual-branch mul...

Thermally Reversible Transformation between Two Isomers of Silver Sulfide Magic-Size Clusters

Abstract Isomers of semiconductor magic-size clusters (MSCs) share the same molecular formula but can exhibit distinct optical and electronic properties. Most of the reported MSC isomers have been so far limited to cadmium chalcogenides. Herein, we report the reversible transform...

Design of a load-responsive mechanical pressure limiter for overload protection in hydraulic actuators

To improve the overload protection performance of hydraulic actuators under dynamic load variations, a load-responsive mechanical pressure-limiting device is proposed with a wheel loader as the application background. The device integrates a pressure-sensitive element, a pressure...

Water-oil interfacial kinetics control enables water-based organic solar cells with 12.59% certified efficiency

Organic solar cells (OSCs) are promising for clean-energy generation, but sustainable production remains constrained by hazardous organic solvents. Aqueous organic-semiconductor nanoparticle (NP) inks offer an environmentally friendly route to OSCs, yet low efficiency and limited...
