A triboelectric generator include at least two yarns, one of which has been infiltrated with a material having a positive triboelectric affinity and one of which has been infiltrated with a material having a negative triboelectric affinity. The at least two yarns are threaded through holes within a disk so that both of the yarns are disposed on both sides of the disk and pass through the holes within the disk. The at least two yarns are helically wrapped (or “coiled”) together on both sides of the disk. During uncoiling, the moving contact between the two yarns, infiltrated with materials having opposite triboelectric affinities, causes an electrical charge to develop. The generated electrical charge can be conducted away for use as electricity.

A semiconductor device includes a first conductive pattern at an upper portion of a first insulating interlayer on a first substrate, a first plurality of conductive nanotubes (CNTs) extending vertically, a second conductive pattern at a lower portion of a second insulating interlayer beneath a second substrate, and a second plurality of CNTs extending vertically. A lower surface of the second insulating interlayer contacts an upper surface of the first insulating interlayer. At least a portion of a sidewall of each of the first plurality of CNTs is covered by the first conductive pattern, and at least a portion of a sidewall of each of the second plurality of CNTs is covered by the second conductive pattern. The first and second conductive patterns vertically face each other, and at least one of the first plurality of CNTs and at least one of the second plurality of CNTs contact each other.

A superconductor thermal filter is disclosed that includes a normal metal layer having a first side, an insulating layer overlying the first side of the normal metal layer, and a multilayer superconductor structure having a first side overlying a side of the insulting layer opposite the side that overlies the normal metal layer. The multilayer superconductor structure is comprised of a plurality of superconductor layers with each superconductor layer having a smaller superconducting energy band gap than the preceding superconductor as the superconductor layers extend away from the normal metal layer. The thermal filter further includes a normal metal layer quasiparticle trap having a first side and a second side with the first side being disposed on a second side of the multilayer superconductor. A bias voltage is applied between the normal metal layer and the normal metal layer quasiparticle trap to remove hot electrons from the normal metal layer.

A mesoporous, nanocrystalline, metal oxide construct particularly suited for capacitive energy storage that has an architecture with short diffusion path lengths and large surface areas and a method for production are provided. Energy density is substantially increased without compromising the capacitive charge storage kinetics and electrode demonstrates long term cycling stability. Charge storage devices with electrodes using the construct can use three different charge storage mechanisms immersed in an electrolyte: (1) cations can be stored in a thin double layer at the electrode/electrolyte interface (non-faradaic mechanism); (2) cations can interact with the bulk of an electroactive material which then undergoes a redox reaction or phase change, as in conventional batteries (faradaic mechanism); or (3) cations can electrochemically adsorb onto the surface of a material through charge transfer processes (faradaic mechanism).

The present invention relates to a manufacturing method of a nanodisc comprising an olfactory receptor protein, and a nanodisc comprising an olfactory receptor protein manufactured by the same, and more specifically, a manufacturing method of a nanodisc comprising an olfactory receptor protein using E. coli, and a nanodisc comprising an olfactory receptor protein manufactured by the same.

According to the present invention, nanodiscs (T13NDs) are manufactured by producing receptors used in T13NDs from E. coli, thereby being able to mimic the original receptor structure and can be stable in water and atmospheric environments, and by the same, not only selectivity, accuracy, and reproducibility can be improved, but also it was possible to selectively detect cadaverine, which is known to occur from rotten foods, through the improved performance ability.

A method for increasing a service lifetime of an electronic component includes applying a topological insulator coating layer on a surface of the electronic component and performing a test on the electronic component with the topological insulator coating layer applied thereto. The electronic component with the topological insulator coating layer exhibits at least a 100% improvement during the test when compared to an otherwise equivalent electronic component without the topological insulator layer applied thereto. The electronic component with the topological insulator coating layer exhibits at least a 100% improvement during the test when compared to an otherwise equivalent electronic component with a graphene layer applied thereto. The test includes at least one of: a waterproofness test, an acetic acid test, a sugar solution test, and a methyl alcohol test.

A vascular graft includes deformable sleeves that include an electrical component. The electrical component can be variable-resistance or piezoelectric, in embodiments, such that deformation of the sleeves due to pressure changes create or modify an electrical signal. A transponder can then transmit information relating to the pressure inside and outside of the vascular graft.
