Optimising sequential electrodeposition to control structure and pseudocapacitive performance in PEDOT/MnOx electrodes

This work systematically investigates how PEDOT and MnOx deposition parameters affect the electrochemical performance of sequentially electrodeposited composites by independently varying the growth potential and synthesis charge of each layer. The PEDOT underlayer transformed the...

Understanding the Drivers of Environmental Innovation: Regulatory Pressures, Economic Incentives and Market Mechanisms

ABSTRACT This study examines the associations between regulatory pressures, economic incentives, market‐related mechanisms and firms' reported environmental benefits from innovation, distinguishing between benefits related to internal production processes and those that benefit e...

Tensile properties and bond behaviour to concrete of thermoplastic GFRP bars at elevated temperature

Thermoplastic glass fibre-reinforced polymer (GFRP) bars offer a more versatile and sustainable alternative to conventional thermoset bars, given their ability to be bent on-site and potential for easier recycling. However, as a newly developed technology, its mechanical performa...

A Review of Wastewater for Hydrogen Production by Electrochemical Processes

Wastewater electrochemical processes and electrolysis—defined here as direct electrochemical water splitting using wastewater as the electrolyte, without biological hydrogen-producing pathways or external organic oxidation processes—have emerged as compelling dual-function strate...

WAPOSAL: a multi-regional wave dataset from satellite altimetry for significant wave height, period estimation, and wave power density

Abstract. Accurate assessment of wave power density (WPD) is essential for marine renewable energy development and for validating numerical wave models, particularly in coastal and nearshore regions where in situ observations are sparse. This study presents a high-resolution, mul...

Stability and Bifurcation of a Multi-Trait Eco-Evolutionary Logistic-Type Model

We extend a two-dimensional discrete-time eco-evolutionary logistic model to the case of finitely many quantitative traits. The original planar model couples population density to a single mean trait under stabilizing selection; the extension retains this mechanism while allowing...

Resilient train formation control for ASVs under intermittent communication environment via actor–critic reinforcement learning

To address the train formation task of autonomous surface vehicles (ASVs) operating under intermittent communication environment, this paper investigates the problem of resilient formation robust control for ASVs. First, a resilient distributed leader predictor (RDLP) is designed...

Federated EGA in the European and Global Human Data Ecosystem

This Federated EGA in the European and Global Human Data Ecosystem white paper sets out our vision for the future role of Federated EGA (FEGA) in supporting secure, responsible and FAIR reuse of controlled-access human data. It describes how FEGA has developed into an operational...

Ultrasonic Guided Wave Localization and Classification of Damage-like Perturbations in a CFRP Plate Using a PZT Network

Ultrasonic guided waves acquired using permanently bonded piezoelectric transducers enable large-area monitoring of composite structures. For practical structural health monitoring; however, both the location and the condition of a structural change are critical. This paper prese...

Stem-cell modeling of cerebellar dysfunction of Angelman syndrome

Angelman syndrome is a severe neurodevelopmental disorder caused by loss of function of the maternal allele of the neuron-specific imprinted gene UBE3A. Although Angelman syndrome presents with developmental delay, ataxia, epilepsy, and speech impairment, the contribution of spec...

A multi-level framework for type-safe topological structures with efficient connectivity queries

We present a framework for representing and querying multi-type topological structures with applications to finite element meshes, hypergraphs, and hierarchical data. The framework introduces a four-level architecture—O2M (One-to-Many), M2M (Many-to-Many), MM2M (Multi-type Many-t...
