Abstract: An electrode structure for a secondary battery includes a potential sheath capable of suppressing a side reaction between an electrode and an electrolyte through electric potential control. The electrode structure for the secondary battery uses the electric potential control so that an unstable SEI layer, which causes decrease in cycle characteristic and capacity of an anode material, occurs only on the surface of a potential sheath without occurring on the surface of the anode active material, thereby being capable of completely solving the problems of the existing nanostructured electrode.

Abstract: Provided are a rubber composition for tire containing raw material rubber and cellulose whiskers, and a tire produced from the same composition and having excellent general properties. Since the rubber composition for tire contains cellulose whiskers having superior reinforcing properties than rubber reinforcing materials, the rubber composition for tire can provide a tire having markedly enhanced properties compared to tires using the conventional rubber reinforcing materials. Also, when cellulose whiskers are applied to the rubber composition for tire, the content of the conventional rubber reinforcing materials can be reduced. As a result, the elongation ratio and low-fuel consumption performance that have been considered poor due to the use of conventional rubber reinforcing materials can be improved to a superior level, and a lightweight tire can be provided.

Abstract: A solar cell using a p-i-n nanowire that may generate light by absorbing solar light in a wide wavelength region efficiently without generating light loss and may be manufactured with a simplified process and low cost.

The PD includes a graphene thin film having a sheet shape formed by means of a graphene deposition process using a vapor-phase carbon (C) source and a nanoparticle layer formed on the graphene thin film and patterned to define an electrode region of the graphene thin film, the nanoparticle layer being formed of nanoparticles without a matrix material. The PD has a planar structure using the graphene thin film as a channel and an electrode and using nanoparticles as a photovoltaic material (capable of forming electron-hole pairs due to photoelectron-motive force caused by ultraviolet (UV) light). Since the PD has a very simple structure, the PD may be fabricated at low cost with high productivity. Also, the PD includes the graphene thin film to reduce power consumption.
