Castor Seed Bio -Transformer Oil As An Alternative To Conventional Transformer Oil
, 2016 In search of solution to the harmful ecological problems due to toxicity and non-biodegradability posed by conventional transformer insulation oil (mineral oil), the production of transformer oil from castor seed oil (vegetable oil) was carried out. The oil was extracted using N-hexane and was refined.

Mono‐Material Polydisulfides for Pressure Sensitive Adhesive Tapes With Closed‐Loop Recyclability
Advanced Functional Materials, EarlyView.A high‐performance pressure‐sensitive adhesive (PSA) tape is developed where both the adhesive layer and plastic backing layer can be recycled back to monomer in a closed‐loop cycle. Both layers of the tape are composed of analogous polydisulfide copolymers using only two unique monomers, thus giving it a mono‐material design and enabling recycling of ...

Study of surface discharge behaviour at the oil-pressboard interface
, 2013 This thesis is concerned with the surface discharge behaviour at the oil-pressboard interface. For large transformers this is classified as a serious failure mode because it can lead to catastrophic failure under normal AC voltage operating conditions ...

Preferential Interfacial Engineering of Hydrogels via Interdigitated Nanoparticle Assembly
Advanced Functional Materials, EarlyView.Robust surface functionalization of hydrogel surfaces is performed via interdigitated metal nanoparticle assembly, inducing strong affinity with the hydrogel matrix. The partially exposed nanoparticle domains act as interfacial nanobridges that mediate both chemical and physical bonding with diverse materials, including small molecules, fluorous ...
