In this hydrogen refining pressure-boosting device the flow path surface of a cathode-side separator is sized so as to be contained on the inside of the flow path surface of an anode-side separator, in the direction of a plane parallel to a solid polymer electrolyte membrane.Type: GrantFiled: August 5, 2014Date of Patent: July 3, 2018Assignee: UNIVERSITY OF YAMANASHIInventor: Masahiro Watanabe

Patent number: 9847439Abstract: Titania is a semiconductor and photocatalyst that is also chemically inert. With its bandgap of 3.0, to activate the photocatalytic property of titania requires light of about 390 nm wavelength, which is in the ultra-violet, where sunlight is very low in intensity. A method and devices are disclosed wherein stress is induced and managed in a thin film of titania in order to shift and lower the bandgap energy into the longer wavelengths that are more abundant in sunlight. Applications of this stress-induced bandgap-shifted titania photocatalytic surface include photoelectrolysis for production of hydrogen gas from water, photovoltaics for production of electricity, and photocatalysis for detoxification and disinfection.Type: GrantFiled: June 20, 2016Date of Patent: December 19, 2017Inventor: John M.

Patent number: 9518077Abstract: The present disclosure provides methods for producing chitosan derivatives and the derivatives formed by these methods. The processes of the present disclosure utilize electrochemical methods to functionalize and/or modify amine and/or hydroxyl groups present on chitosan, to form new derivatives. In embodiments, a chloro-chitosan derivative may be prepared. The altered cationic affinity of these derivatives make them excellent candidates for biomedical applications, including pharmaceuticals, as well as food applications.Type: GrantFiled: February 1, 2013Date of Patent: December 13, 2016Assignee: The Research Foundation for the State University of New YorkInventors: Gary P.
