1. Ferroelectric domain engineering and characterization for photonic applications
Abstract : Lithium niobate (LiNbO3) and KTiOPO4 (KTP) are ferroelectric crystals of considerable interest in different fields of optics and optoelectronics. Due to its large values of the nonlinear optical, electro-optic (EO), piezoelectric and acousto-optical coefficients, LiNbO3 is widely used for laser frequency conversion using the quasiphase matching (QPM) approach where the sign of nonlinearity has been periodically modulated by electric field poling (EFP).

2. Composites studied by moiré methods and high speed photography
Abstract : Fibre composites are today used as construction material in a growing number of applications. Carbon fibres/epoxy matrix composites are employed in high performance applications as aircrafts where a high stiffness/weight ratio is important. READ MORE

3. Healing of tympanic membrane perforations : an experimental study
Abstract : Most acute tympanic membrane perforations heal spontaneously without any residual complication, whereas a fraction transforms into a chronic perforation. The current treatment of a chronic perforation is surgical repair, which is a costly, time consuming and uncomfortable procedure particularly for the pediatric patients. READ MORE

4. Stiffness changes of the tympanic membrane in otitis media
Abstract : Acute purulent otitis media and otitis media with effusion, are common diseases in childhood. Years later some of the children will get "complications", such as retraction pockets and cholesteatoma, that often need advanced surgical treatment. READ MORE
