Patent number: 10875015Abstract: Methods for making porous materials having metal alloy nanoparticles formed therein are described herein. By preparing a porous material and delivering the precursor solutions under vacuum, the metal precursors can be uniformly embedded within the pores of the porous material. Once absorption is complete, the porous material can be heated in the presence of one or more functional gases to reduce the metal precursors to metal alloy nanoparticles, and embed the metal alloy nanoparticles inside of the pores. As such, the metal alloy nanoparticles can be formed within the pores, while avoiding surface wetting and absorption problems which can occur with small pores.Type: GrantFiled: September 24, 2018Date of Patent: December 29, 2020Assignees: Toyota Motor Engineering & Manufacturing North America, Inc., Toyota Jidosha Kabushiki Kaisha, The University of AkronInventors: Li Qin Zhou, Kan Huang, Tomoyuki Nagai, Hongfei Jia, Hisao Kato, Xiaochen Shen, Zhenmeng Peng

Patent number: 10875016Abstract: A micro analysis chip comprises an inlet and a fluid flow path communicating thereto. The fluid flow path comprises a first flow path, a second flow path, and a third flow path arranged continuously along a longitudinal direction of the fluid flow path. An antibody is bound on at least one peripheral surface selected from the group consisting of peripheral surfaces of the second and third flow paths. A cross-sectional area of the third flow path is constant or increased monotonically along a direction X from the second flow path toward the third flow path. A cross-sectional area of the second flow path is increased monotonically along the direction X from the one end to the other end of the second flow path. A cross-sectional area of the first flow path is larger than a cross-sectional area at the one end of the second flow path.Type: GrantFiled: February 20, 2018Date of Patent: December 29, 2020Assignees: PANASONIC CORPORATION, IMEC VZWInventors: Shuji Sato, Yasuaki Okumura, Yukari Nishiyama, Tatsurou Kawamura, Ben Jones, Liesbet Lagae, Tim Stakenborg

Patent number: 10875020Abstract: An optical waveguide comprises multiple layers of solid-state material disposed on a substrate. One of the layers is a lifting-gate valve made of a high refractive index material. The device provides for better optical confinement in microfluidic channels, and has the capability to integrate both optical signals and fluid sample processing. The optical paths on the chip are reconfigurable because of the use of a movable microvalve that guides light in one of its positions.Type: GrantFiled: September 1, 2016Date of Patent: December 29, 2020Assignee: The Regents of the University of CaliforniaInventor: Holger Schmidt
