Dynamic Reconstruction of Interfacial Hydrogen‐Bond Networks Enhances CO2 Electroreduction Selectivity

EcoEnergy, EarlyView.
Concentrated NaClO4 dynamically reconstructs interfacial hydrogen‐bond networks during CO2 electroreduction, restricting proton transport and stabilizing CO‐derived intermediates. Multinuclear NMR, infrared spectroscopy, and simulations reveal electrolyte‐mediated electric‐double‐layer regulation, which suppresses hydrogen evolution and enhances C–C ...

Toward Single‐Crystal Upcycling of Degraded Lithium‐Ion Battery Cathodes

EcoEnergy, EarlyView.
This review first summarizes the degradation mechanisms of polycrystalline cathodes, emphasizing the role of grain boundaries and rock‑salt phase formation. It then highlights the main optimization pathways (surface reconstruction, rapid structural repair, PC‑to‑SC transformation, and interface engineering) and the three conversion methods (SSU, MSAU ...

Artificial Intelligence in Optical Coherence Tomography‐Based Ophthalmic Imaging: From Automated Diagnosis to Personalized Disease Monitoring

Eye &ENT Research, EarlyView.
ABSTRACT Artificial intelligence (AI) is increasingly applied to optical coherence tomography (OCT) in ophthalmology, but evidence for automated diagnosis is stronger than evidence for longitudinal monitoring. This narrative review evaluates OCT‐based AI with emphasis on disease monitoring and progression, particularly in retinal disease and glaucoma ...

The translational asymmetry of corpus callosotomy: Two literatures that answered different questions

Epilepsia Open, EarlyView.
Abstract Corpus callosotomy is an established palliative operation for drug‐resistant epilepsy dominated by drop attacks, and it is performed in three extents: anterior, usually of the anterior two‐thirds; total, in one or two stages; and selective posterior, which preserves the genu and rostral body.

Stress Analysis of Slab Track System Using Dimensional Analysis

, 2011
版式軌道是由鋼軌、扣件、混凝土版與路基組成之複雜系統，若以理想、之彈性理論進行分析將無法較精確地掌握其力學行為。而版式軌道在不考慮、以鋼筋混凝土或預力混凝土方式設計時，其型態與剛性路面之的結構型類似。因此，本研究之主要目的在以軌道力學理論為基礎，結合剛性鋪面力學分析之方式，建立新式的版式軌道力學分析方法。研究中以自由體圖之概念，將版式軌道系統分成軌道與混凝土版之模組，並分別應用軌道力學理論與剛性鋪面之版理論進行分析。本研究採用因次分析的方法，配合三維有限元素法數值運算與統計分析之方式 ...

Whole‐House Thermal Bridge Modelling for Accurate Retrofit Energy Prediction

Energy Science &Engineering, EarlyView.
This study models thermal bridging in a UK semi‐detached house across pre‐ and post‐retrofit scenarios using piecemeal and whole‐house approaches with EWI and IWI. Whole‐house retrofits reduce heat transfer coefficient by 60%; findings demonstrate that default values are often unrepresentative and advocate tailored Ψ value databases.

Modelling the acoustic performance of slab tracks

, 2020
Transport is a major contributor to anthropogenic greenhouse gas emissions. Railway transport has a small footprint compared to other means of transport. This is one reason for the construction of new high-speed railway lines world-wide. These lines are often constructed using slab track technology, in which the traditional track configuration of ...

A Genetic Algorithm‐Optimized LSTM Framework for Mechanics‐Conditioned Reconstruction of Stress–Strain Curves in High‐Performance Cementitious Materials

Energy Science &Engineering, EarlyView.
GA‐optimized LSTM for full stress–strain curve prediction of high‐performance cementitious materials. Compression‐test data are preprocessed (cleaning, normalization, interpolation/standardization, and Savitzky–Golay smoothing). A Genetic Algorithm tunes LSTM hyperparameters, while a physics‐informed loss enforces stiffness, peak response ( σ max ...

Influence of Adhesive Type on Heat Induced Delamination in Tension Loaded Shear Lap Cross‐Laminated Timber Samples Exposed to Radiant Heat Flux

Fire and Materials, EarlyView.
ABSTRACT Heat induced delamination (HID) is a phenomenon in engineered wood products which may result in the detachment of the bonded timber lamellae before charring propagates to the bond line interphase. This study aims to correlate the thermal degradation of two 1‐c‐polyurethane adhesives at the microscale to the thermo‐hydro‐mechanical behaviour of
