Diene Dione dye which has donor and acceptor molecules can act as non linear dye for optoelectronic application. The dye was found to have some non linearity can be exploited in devices such as LED, electro optic and sensors.
The dye can be fabricated as cross linked or grafted polymer in thin film form. Optimisation of exposure time, voltage applied and excitation wavelength can change the refractive index(n) of the doped polymer. The change in refractive index of polymer due to doped dye is valuable in the construction of devices such as electro optic, light emitting diode, laser amplifiers and sensors. This dye was also found to have fluorescence properties when exposed to uv light. Hence, this natural dye has potential as dopant for optoelectronic devices which is non toxic and abundance in nature

Creating a new material that is useful, easily reproducible and sustainable source of energy that is environmental friendly due to its biodegradable properties is the objective of this research work. A new solid mixture in the form of pellets and thin films based on amino acid were prepared by low sintering and casting method. It was found that the samples are ionic and showed reasonably good electrical conductivity that is in the range of 10-4 S/cm. Hence these materials are suitable for application in solid state batteries. This organic polymer is chosen as the host material or additive due to its molecular structure where it can be complexed with lithium salts such as lithium iodide or lithium triflate and hence a superionic lithium based solid electrolyte may be produced. Its plastic characteristic which helps to rubberize molten salt systems and recyclability property can also be considered as added values in using amino acid as a conducting ion.

Particle strands were successfully produced from oil palm trunk using a flaker. Particleboard was then produced using urea formaldehyde resin. Properties of the Oil palm board surpassed the minimum requirements of the BS 5669 standards fro general purpose particleboard. Particleboard made from the particle strands is very much suitable for furniture manufacturing and it also overcome the problem of raw material shortage in the particleboard industry.
