Fluorinated Carnitine Derivatives as Tools to Visualise Carnitine Transport and Metabolism
Advanced Science, EarlyView.Fluorinated carnitines, fluoromethyl carnitine (FMC) and [18F]fluoromethyl carnitine ([18F]FMC), are synthesised and established as powerful probes to interrogate carnitine biology. The multimodal detection facilitated by fluorine labelling, including 19F NMR, mass spectrometry, and positron emission tomography imaging, allowed for visualisation of ...

Bio‐Based Wax Interfaces for Droplet Energy Harvesting at Fluoropolymer‐Like Output Levels
Advanced Science, EarlyView.Replacing unsustainable fluorinated polymers in droplet‐based energy harvesters is usually limited by low power outputs, but carefully selected bio‐based polymers are capable of creating fluoropolymer‐like voltage outputs. Abstract Droplet impact and rebound on solid surfaces has emerged as a promising method for energy harvesting, typically ...

Imperfection in Semiconductors Leading to High Performance Devices
Advanced Science, EarlyView.Crystalline perfection is typically pursued in semiconductors to enhance device performance. However, through modeling and experimental work, we show that defects can be strategically employed in a specific detection regime to increase sensitivity to extreme values. GaN diodes are demonstrated to effectively detect high‐energy proton beams at fluxes as

Fourier multipliers in Hilbert spaces
, 2017 This is a survey on a notion of invariant operators, or Fourier multipliers on Hilbert spaces. This concept is defined with respect to a fixed partition of the space into a direct sum of finite dimensional subspaces. In particular this notion can be applied to the important case of $L^2(M)$ where $M$ is a compact manifold $M$ endowed with a positive ...

Advanced Science, EarlyView.Valence‐engineering of CeO2 redox modulator can remove the highly oxidative by‐products and accelerate the oxidation state transitions of Co/Fe centers in FeCo dual‐atom catalyst during oxygen reduction/evolution electrocatalysis. Therefore, the stability and activity issues are resolved, significantly enhancing the overall performance when used as an ...

Solid Harmonic Wavelet Bispectrum for Image Analysis
Advanced Science, EarlyView.The Solid Harmonic Wavelet Bispectrum (SHWB), a rotation‐ and translation‐invariant descriptor that captures higher‐order (phase) correlations in signals, is introduced. Combining wavelet scattering, bispectral analysis, and group theory, SHWB achieves interpretable, data‐efficient representations and demonstrates competitive performance across texture,

Local and global low-regularity solutions to generalized Leray-alpha equations
Electronic Journal of Differential Equations, 2015 It has recently become common to study approximating equations for the Navier-Stokes equation. One of these is the Leray-alpha equation, which regularizes the Navier-Stokes equation by replacing (in most locations) the solution u with $(1-\alpha^2 ...
