Stable cellulose nanofibril microcapsules from Pickering emulsion templates
Electrostatic attractions are essential in any complex formation between the nanofibrils of the opposite charge for a specific application, such as microcapsule production. Here, we used cationized cellulose nanofibril...

An analytical study of the pulsed thermography defect detection limit
A simple modification of the one-dimensional expression for the thermal contrast of a layer provides a useful prediction of peak contrast temperature and contrast peak time for defects of all aspect ratios. The new analytical...

An objective comparison of pulsed, lock-in, and frequency modulated thermal wave imaging
An objective comparison of three different thermal non-destructive evaluation (NDE) techniques - pulsed thermography (PT), lock-in (LI) thermography, and frequency modulated thermal wave imaging (FMTWI), has been carried out on...

A comparison of the pulsed, lock-in and frequency modulated thermography nondestructive evaluation techniques
Pulsed, lock-in and frequency modulated thermography are three alternative nondestructive evaluation techniques. The defect imaging performance of these techniques are compared using: matched excitation energy; the same carbon...

LED optical excitation for the long pulse and lock-in thermographic techniques
High power light emitting diode (LED) arrays have been investigated as excitation sources for long pulse and lock-in thermography. Images of artificial defects in a carbon fibre reinforced plastic (CFRP) composite sample are...
