Surface Behavior Regulation of Intermediates on the Copper‐Based Catalysts for Enhancing Electrocatalytic CO2 Reduction to Ethylene

open access: yesSmall, EarlyView.
This review highlights the mechanistic regulation of *CO intermediates in electrocatalytic CO2 reduction to ethylene. Strategies including surface/structural engineering, valence tuning, interface modulation, and deoxygenation pathway control are systematically mapped to *CO generation, coupling, and transformation, offering guidance for mechanism ...

An inverse problem of reconstructing the electrical and geometrical parameters characterising airframe structures and connector interfaces [PDF]

open access: yes, 2007
This article is concerned with the detection of environmental ageing in adhesively bonded structures used in the aircraft industry. Using a transmission line approach a forward model for the reflection coefficients is constructed and is shown to have an ...

Dissecting the Structural Features of Folding Asymmetry and Transient Misfolding in a Multidomain PDZ Scaffold

open access: yesSmall Science, EarlyView.
This study reveals how a multidomain protein can misfold through subtle internal frustrations rather than by swapping entire domains. Using Φ‐value analysis, the authors map the structural features that govern folding and misfolding in the X11 PDZ1–PDZ2 scaffold.

Preliminary tests of vulnerability of typical aircraft electronics to lightning-induced voltages [PDF]

open access: yes
Tests made on two pieces of typical aircraft electronics equipment to ascertain their vulnerability to simulated lightning-induced transient voltages representative of those which might occur in flight when the aircraft is struck by lightning were ...

Fail‐Controlled Classifiers: A Swiss‐Army Knife Toward Trustworthy Systems

open access: yesSoftware: Practice and Experience, EarlyView.
ABSTRACT Background Modern critical systems often require to take decisions and classify data and scenarios autonomously without having detrimental effects on people, infrastructures or the environment, ensuring desired dependability attributes. Researchers typically strive to craft classifiers with perfect accuracy, which should be always correct and ...

Design of lightning protection for a full-authority digital engine control [PDF]

open access: yes
The steps and procedures are described which are necessary to achieve a successful lightning-protection design for a state-of-the-art Full-Authority Digital Engine Control (FADEC) system. The engine and control systems used as examples are fictional, but

Organic Representation as a Critical Media Approach to Leadership Studies in Popular Culture

open access: yesNew Directions for Student Leadership, Volume 2025, Issue 185, Page 75-80, Spring 2025.
ABSTRACT This article applies the critical media concept of organic representation to leadership studies as an analytic of how various creators in popular culture today are not just writing inclusive storytelling but, more notably, modeling new modes of production and self‐presentation that are actively challenging hegemonic industry practices and ...

Investigating Spatial‐Temporal Optical Emission Spectroscopy of Unstable Positive Leaders in Long Sparks Under Atmospheric Pressure

open access: yesHigh Voltage, EarlyView.
ABSTRACT This study explores exciting state species and reaction pathways in positive leaders to better understand the breakdown mechanisms of long air gap discharges and natural lightning. Emission spectra from an unstable positive leader in a 1 m rod‐plate air gap under switching impulse voltages were observed, spanning 300–800 nm.

Investigation of Dielectric and Thermal Properties of Mineral Oil‐Based Fe3O4‐Coated SiO2 Core‐Shell Nanofluids

open access: yesHigh Voltage, EarlyView.
ABSTRACT This study investigates the dielectric and thermal properties of transformer oil‐based nanofluids incorporating Fe3O4‐coated SiO2 core–shell nanoparticles as nanofillers. The nanoparticles were synthesised with varying shell thicknesses, and two samples underwent surface treatment.
