Publication number: 20230364585Abstract: The present disclosure discusses a method of separating and/or purifying polynucleotides. The method includes injecting a sample into a chromatographic column that is packed with a porous sorbent having a pore size that substantially excludes the polynucleotides from the sorbent. This restricted access to the sorbent allows separation of large polynucleotides from each other and from smaller molecular weight impurities.Type: ApplicationFiled: May 8, 2023Publication date: November 16, 2023Applicant: Waters Technologies CorporationInventors: Matthew A.

Patent number: 11661788Abstract: A recording head has a near-field transducer that extends a first distance away from a media-facing surface. Two subwavelength focusing mirrors are at an end of a waveguide proximate the media-facing surface and extend a second distance away from the media-facing surface that is less than the first distance. The subwavelength mirrors are on opposite crosstrack sides of the near-field transducer and separated from each other by a crosstrack gap. The subwavelength focusing mirrors each include a first material at the media-facing surface and a plasmonic material that covers an edge of the subwavelength focusing mirror that faces the near-field transducer. The first material is more mechanically robust than the plasmonic material.Type: GrantFiled: January 25, 2022Date of Patent: May 30, 2023Assignee: Seagate Technology LLCInventors: Weibin Chen, Nan Zhou, Ruoxi Yang, Michael Allen Siegler

Patent number: 11028878Abstract: The present application discloses a bearing structural member, a support, a joint assembly and a tube section assembly, wherein the maximum counter force provided by the bearing structural member under an external load is an own designed threshold value, namely when the external load is greater than the designed threshold value of the bearing structural member, the bearing structural member deforms, and provides a counter force equal to the designed threshold value; the support includes at least one bearing structural member; and the joint assembly and the tube section assembly are both equipped with the support. When the external load is not high and is less than the designed threshold value, the bearing structural member may effectively suppress the deformation just like a rigid structural member; when the external load exceeds the designed threshold value, the bearing structural member may deform, and provide a stable counter supporting force less than the external load.Type: GrantFiled: January 12, 2018Date of Patent: June 8, 2021Assignees: China Communications Construction Co.
