Abstract: A conductive nanocomposite which contains a mixed polymer matrix which contains a rubber and a polyether, carbon nanoparticles, and transition metal nanoparticles. The conductive nanocomposite has a nonlinear relationship between resistivity and temperature characterized by an exponential increase reaching a peak resistivity followed by an exponential decrease as temperature increases. Also disclosed is a method of forming the conductive nanocomposite involving mixing the components, aging, and pressing. The conductive nanocomposite forms a component of a heater that is self-regulating as a result of the nonlinear relationship between resistivity and temperature of the conductive nanocomposite. The nanocomposite also forms a component of a thermistor.

Abstract: A thin film coating apparatus is disclosed, including a sample holder rotatably configured in the apparatus. The sample holder is coupled to a motor configured to rotate the sample holder. The apparatus includes a heating chamber disposed around the sample holder. The heating chamber is configured to supply heat to a substrate loaded on the sample holder. The apparatus includes a top cover configured to selectively allow access to the substrate loaded on the sample holder. A controller is configured to: detect a speed of rotation of the sample holder; and operate the top cover to allow access to the substrate loaded on the sample holder when the detected speed of rotation of the sample holder is within a predefined range.

CPC classification number: H01M4/608 , H01M10/36 , H01M2004/027
Abstract: In the present disclosure, a p-n organic battery comprising a p-type organic semiconductor and n-type organic semiconductor as active electrodes, anode and cathode current electrodes, separator and electrolyte and a method of fabricating the same is disclosed. The p-n organic battery has an p-type organic semiconductor separated from a n type organic semiconductor by an aqueous electrolyte solution, contained in an insulating vessel with suitable terminals (not shown) being provided in electric contact with the anode current electrode and the cathode current electrode. The aqueous electrolyte can comprise water, and a transition metal salt such as NiCl2, CuCl2 dissolved in the water.
