Nitrile Butadiene Rubber

This study was done to investigate the microstructures of nanocrystalline cellulose (NCC) after hydrolysis with mineral acid concentrated. The optimum NCC was achieved through acid hydrolysis and the NCC was used as a reinforcement in nitrile butadiene rubber composites. The Field Emission Scanning Microscopy (FESEM) was used to study the structures and surfaces of the NCC and composites produced. The NCC that was synthesis from microcrystalline cellulose (MCC) found to be more individual and agglomerated due to hydrogen bonding between the NCCs, the more individual NCC produced would create more surface area to be bonded with NBR as a reinforcement. More surface area of NCC was good to create physical bonding with NBR and increase mechanical performance of composites. The NCCs in NBR composite found to form agglomeration caused by different properties that exhibited by both materials. This can restrict and reduce the performance of composite produced. A combination of these materials can be used as a reinforcement but need more attention on the modification to make these materials more compatible. Further research can be done to find the best way to prevent agglomeration between these both materials.

Shear Transformation

An interest in NiTi alloys with near stoichiometric composition (55 NiTi) has intensified since they were found to exhibit a unique mechanical shape memory effect at the Naval Ordnance Laboratory some twelve years ago (thus refered to as NITINOL alloys). Since then, the microstructural mechanisms associated with the shape memory effect have been investigated and several interesting engineering applications have appeared.The shape memory effect implies that the alloy deformed from an initial shape will spontaneously return to that initial state upon heating. This behavior is reported to be related to a diffusionless shear transformation which takes place between similar but slightly different CsCl type structures.
