  • Publication number: 20230321628
    Abstract: Provided is an absorption method of an element belonging to periods 4 to 6 and groups 3 to 15 of the periodic table. The method includes: preparing mesoporous alumina that satisfies at least one of the following items: (1) a surface hydroxyl content is 3.5 mmol/g or more; (2) a low-temperature CO2 desorption amount in CO2 thermal desorption amount spectrometry is 5 ┬Ámol/g or more; and (3) a low-temperature NH3 desorption amount in NH3 thermal desorption amount spectrometry is 25 ┬Ámol/g or more; and bringing a liquid containing an absorption target element in contact with the mesoporous alumina to absorb the absorption target element in the mesoporous alumina. The absorption target element is at least one type selected from the group consisting of an element belonging to periods 4 to 6 and groups 3 to 15 of the periodic table.

  • Publication number: 20230159347
    Abstract: Provided is a method for producing a porous metal oxide. The method includes: preparing a slurry by mixing a metal source, a pore forming agent and an aqueous solvent; drying the slurry to obtain a metal oxide precursor; and sintering the metal oxide precursor to generate a porous metal oxide. The metal source is an organometallic compound or hydrolyzate thereof containing a metal that makes up the porous metal oxide; the pore forming agent is an inorganic compound that generates a gas by decomposing at a temperature equal to or lower than a temperature at which the metal oxide precursor is sintered; and the slurry is prepared using 50 parts by weight or more of the pore forming agent with respect to 100 parts by weight of the metal source.

  • Patent number: 11576528
    Abstract: An herb grinding and rolling apparatus configured to provide availability of all of the elements required to facilitate the grinding of herbs and dispensing into a paper for subsequent rolling and smoking. The present invention includes a body wherein the body is formed from a first section, a second section and a third section. The three sections are foldably coupled so as to move the body between a folded position and an unfolded position. The first section includes an herb grinding compartment having an interior volume and an herb grinding plate. The second section and third section are configured to receive, retain and dispense sheets of paper suitable for use in rolling ground herbs. The paper includes perforation seams at one end thereof to produce a desired shape for an end of a rolled paper. The herb grinding compartment includes a funnel formation in the sidewall thereof.

  • Patent number: 11146832
    Abstract: This disclosure describes techniques for distributed storage of files that represent video content across different storage tiers to reduce the amount of computing resources used to store the files, while maintaining a low latency when responding to user requests to stream the video content. Video streaming services support the streaming of video content at different resolutions to support various user devices and/or user preferences. To provide streaming of a particular video content item at different resolutions, the video streaming services may store multiple files that represent the video content item for the different resolutions and stream at different bitrates to user devices. The techniques described herein include storing files configured to stream a video content item at different bitrates (and for different display resolutions) in a tiered storage structure to reduce the amount of computing resources taken to store the files.

  • Patent number: 7163889
    Abstract: The present invention provides a low dielectric constant copper diffusion barrier film suitable for use in a semiconductor device and methods for fabricating such a film. Some embodiments of the film are formed of a silicon-based material doped with boron. Other embodiments are formed, at least in part, of boron nitride. Some such embodiments include a moisture barrier film that includes oxygen and/or carbon. Preferred embodiments of the copper diffusion barrier maintain a stable dielectric constant of less than 4.5 in the presence of atmospheric moisture.
