Topological insulators are a new class of quantum materials with metallic (edge) surface states and insulating bulk states. They demonstrate a variety of novel electronic and optical properties, which make them highly promising electronic, spintronic, and optoelectronic materials. We report on a novel conic plasmonic nanostructure that is made of bulk-insulating topological insulators and has a...

Nowadays, the most widely used insulating materials in high voltage equipment such as cables are polymeric insulations due to the numerous merits they possess with regards to electrical performance compared to paper insulations. However, electrical treeing, one of the dielectric pre-breakdown phenomena, has been considered as a major contribution to the failure of insulating polymeric materials...

Liquid paraffin as a coolant fluid can be  applied in electronic devices as a result to its suitable capabilities such as electrical insulating, high heat capacity, chemical and thermal stability, and high boiling point. However, the poor thermal conductivity of paraffin has been confined its thermal cooling application. Addition of high conductor nanoparticles to paraffin can fix this drawback...

Polymers with good insulating properties are widely used in motors, rotating machines and components in power electronics and microelectronics1-3. It is well know that polymer properties can be greatly improved by adding inorganic fillers to form composite polymer. Polyimide has been a polymer of choice in many areas owing to its excellent dielectric properties, high thermal mechanical strength...

Nowadays, energy efficiency and sustainability are the fulcra of building policies. These policies promote use new technologies materials that can reduce primary involved environmental costs construction, guarantying at same time a high level comfort for building’s occupants. Synergy between previous construction techniques should be pursued by employing with low impact optimal thermal insulati...

In this study, ‘Hanfu’ apple trees were used as a test material to determine the effect of a functional protective film on the ability of the trees to withstand temperatures below zero. The functional protective film is a quaternary copolymer prepared by emulsion polymerization of vinyl acetate (Vac), butyl acrylate (NbA), methyl methacrylate (MMA) and acrylic acid (AA). The resulting copolymer...
