Patent number: 10696851Abstract: Intercalation pastes for use with semiconductor devices are disclosed. The pastes contain precious metal particles, intercalating particles, and an organic vehicle and can be used to improve the material properties of metal particle layers. Specific formulations have been developed to be screen-printed directly onto a dried metal particle layer and fired to make a fired multilayer stack. The fired multilayer stack can be tailored to create a solderable surface, high mechanical strength, and low contact resistance. In some embodiments, the fired multilayer stack can etch through a dielectric layer to improve adhesion to a substrate. Such pastes can be used to increase the efficiency of silicon solar cells, specifically multi- and mono-crystalline silicon back-surface field (BSF), and passivated emitter and rear contact (PERC) photovoltaic cells. Other applications include integrated circuits and more broadly, electronic devices.Type: GrantFiled: November 23, 2016Date of Patent: June 30, 2020Assignee: Hitachi Chemical Co., Ltd.Inventors: Brian E.

Patent number: 9758826Abstract: p53-upregulated modulator of apoptosis (PUMA) is a biomarker associated with islet cell health. If PUMA is low, islet cells are typically healthy. If PUMA is high, islet cells are typically unhealthy or dying. PUMA may be measured by either measuring its nucleic or amino acid. PUMA mRNA may be induced by TNF-? stimulation in a time- and dose-dependent manner and ? cell apoptosis is induced through a mitochondrial pathway. TNF-? significantly inhibited glucose-induced preproinsulin precursor mRNA synthesis. Such ? cell stress signaling in human islets indicates overall state of islet health and, ultimately, the risk of onset and/or degree of severity of both type 1 and type 2 diabetes mellitus.Type: GrantFiled: June 17, 2011Date of Patent: September 12, 2017Assignees: City of Hope, Hitachi Chemical Research Center, Inc., Hitachi Chemical Co., Ltd.Inventors: Yoko Mullen, Masato Mitsuhashi, Keiko Omori
