Organic (opto) electronic materials have received considerable attention due to their
applications in thin-film-transistors, light-emitting diodes, solar cells, sensors, photorefractive …

For many years, considerable research efforts have been directed toward exploring the
interaction between light and matter for the prospective replacement of electronic devices …

This review describes recent advances and applications in the field of organic
photorefractive materials, an interesting area in the field of organic electronics and …

Electromagnetic acoustic transducers (EMATs) have a behaviour that depends on the
distance between the transducer and the surface of the material under test, namely the lift …

Non-destructive testing is an important technique, and improvements are constantly needed.
Surface defects in metals are not necessarily confined to orientations normal to the sample …

In this work a method is presented for detecting and locating stress corrosion cracking (SCC)
in stainless steel pipe samples. The method combines laser generation and either laser or …

Surface-breaking defects often have a geometry which is more complicated than the 'normal
slot'used in many calibration tests, and this geometry will affect the reflection and …

A unimorph flexural transducer design is proposed and tested with regard to mode shapes
and frequencies. The transducers consist of a passive metal cap structure, and a thin …

Energy transfer between two laser beams writing a volume hologram in a photorefractive
polymer composite is applied to video-rate optical processing applications. A net increase in …

Defects that propagate from the inside of a structure can be difficult to detect by traditional
non-destructive inspection methods. A non-contact inspection method is presented here that …
