Polymerized Pro‐Estrogen Microneedles via Two Photon Polymerization

Macromolecular Rapid Communications, EarlyView.
Acrylic pro‐drugs of 17β‐estradiol were subjected to spatially controlled two‐photon polymerization to create bespoke microneedle geometries with potential biomedical applications for long‐term transdermal hormone delivery. ABSTRACT Two‐photon polymerization (TPP) is a powerful technique to create microscale structures with high precision, offering ...

A Stopped‐Flow Instrument for Millisecond Timescale Reaction Monitoring on a Standard NMR Spectrometer

Magnetic Resonance in Chemistry, EarlyView.
A new stopped‐flow instrument allows kinetic measurements of reactions 10 milliseconds after initiating them by mixing in a flow cell inserted into a standard NMR probe and spectrometer. High‐speed video, pressure and NMR line‐shape data are used to characterise mixing and stopping, and a protodeboronation reaction with a 5‐millisecond half‐life used ...

Application of Pulsed eddy current technique to stress and residual stress measurement [PDF]

International Journal of Advanced Design and Manufacturing Technology, 2014
Stress and residual stress are the main problems in the operating performance of materials. They are the principal causes of material failure and can affect life time of component. However measurement or predictions of them are typically difficult.

Evaluation of Pulse Eddy Current for Autonomous Airborne Inspections

IEEE Sensors Letters
Unmanned Aerial Vehicles (UAVs) integrated with Pulsed Eddy Current (PEC) technologies present a potential solution for Non-Destructive Testing (NDT) in environments where manual inspection is impractical or hazardous. PEC inspections conducted via UAVs facilitate remote structural health monitoring and offer invaluable thickness measurements for ...

Data fusion algorithm for pulsed eddy current detection

IET Science, Measurement & Technology, 2007
A weighted data fusion algorithm based on matching pursuit (MP)-wavelet packet (WP) atomic decomposition and its applications in pulsed eddy current (PEC) non-destructive testing systems for estimation of feature parameters is presented. MP-WP atomic decomposition is used to estimate each noise-free pulse response from its noisy observation of a single-

Fat/Water Separation at 7 T Using a 3D Radial Sequence With Quasi‐Continuous Echo Times

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To achieve a reliable fat/water separation (FWS) at 7 T using a new 3D radial sequence and reconstruction workflow with quasi‐continuous TE sampling. Methods A 3D radial density‐adapted sequence with quasi‐continuous TE sampling was developed for a 7 T whole‐body MRI system.
