Study on an Internal Gear with Asymmetric Involute Teeth

, 2014
[[abstract]]In this paper, a double envelope concept is used to determine the basic profile of an internal gear with asymmetric involute teeth including driving and driven gears. The teeth of the proposed gear are asymmetric involute teeth. Based on this

Lab‐in‐a‐Tube System Integrating Hierarchically Wrinkled Electrodes and DNAzyme‐Functionalized Beads for Diagnosis of Clostridioides difficile Infection

Advanced Materials, EarlyView.
The point‐of‐care diagnosis of Clostridioides difficile infection remains challenging due to reliance on slow culture and amplification‐based methods. A lab‐in‐a‐tube electrochemical biosensor integrating DNAzymes, antifouling magnetic beads, and a hierarchically structured flow cell enables amplification‐ and culture‐free detection directly in stool ...
