Electronic Coupling and Defect Engineering in Pd–HPW–ZnO Ternary Heterostructures for Ultrasensitive Triethylamine Detection

Abstract Rational design of interfacial electronic structures and defect sites is pivotal for advancing chemiresistive gas sensing, yet achieving synergistic modulation remains a formidable challenge. Herein, we report a ternary Pd–HPW–ZnO heterostructure constructed via the inte...

Simulation study on the mechanical evolution law of double-arch tunnel construction without middle drift

The construction method without middle drift can simplify the construction organization process of double-arch tunnels, thereby improving construction efficiency. However, the mechanical evolution of the surrounding rock and support system, as well as the working mechanism of the...

Need-responsive accessibility supports equitable sustainable development and reshapes migration as evolving human needs

Realizing the Sustainable Development Goals’ commitment to “leave no one behind” requires accessibility that responds to evolving human needs, yet prevailing accessibility assessments remain static and sector-specific, overlooking hierarchical need evolution and behavioral feedba...

Enhanced TetracyclineDegradation by a GaOOH@PDA/PESPhotocatalytic Membrane through S-Scheme Heterojunction Formation:A DFT-Guided Experimental Study

Abstract In this work, we rationally designed and fabricated an S-scheme GaOOH@PDA heterojunction under the guidance of density functional theory (DFT) calculations. Compared with pristine GaOOH, the as-fabricated GaOOH@PDA heterojunction exhibited nearly doubled photocurrent den...

An improved inverse method for estimating disease transmission rates in epidemics with low-incidence data

Abstract The accurate estimation of time-varying transmission rates is fundamental for understanding infectious disease dynamics and implementing effective public health interventions. To this end, we propose an improved inverse method for estimating time-varying transmission rat...

Charge Separation Engineering via ZnCdS/CoNiPPc Schottky Heterojunction to Achieve Efficient Photocatalytic Hydrogen Evolution Coupled with Benzaldehyde Production

To address common challenges in photocatalytic water splitting for hydrogen (H 2 ) production, such as slow hole consumption kinetics and uncontrolled oxidative side reactions, we have designed an innovative Zn 0.5 Cd 0.5 S/bimetallic cobalt/nickel polyphthalocyanine (denoted as...

Anti-swing control of double-pendulum cranes integrating input shaper and nonlinear Quasi-PID scheme

Mitigating swing and enhancing the adaptability have long been central concerns in crane automation. To address this issue, a novel integrated control strategy is proposed by combining the input shaping technique with an improved quasi-PID scheme, and it is applied to double-pend...

Experimental Study on the Physical and Mechanical Properties of Loess Improved by an LM-1 Curing Agent and Cement Composite

This study focuses on loess in the Lanzhou region and employs a self-developed LM-1 ionic cementitious curing agent (mainly sodium silicate) combined with cement for loess improvement. Through mechanical tests, X-ray diffraction (XRD), Scanning Electron Microscopy (SEM) analysis,...
