Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine
Advanced Materials, EarlyView.A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...

Liquid Metal Microrobots for Magnetically Guided Transvascular Navigation
Advanced Materials, EarlyView.Liquid metal‐based microrobots combine magnetic steering, intrinsic X‐ray visibility and softness, to navigate blood vessels even against flow. Under clinically relevant magnetic fields, liquid metal microrobots roll along vessel walls, cross endothelial barriers, and accumulate in target tissues.

Friction torque in the slide bearings
Bulletin of Prydniprovs’ka State Academy of Civil Engineering and Architecture, 2016 Постановка проблеми. Досьогодні підшипники ковзання іще широко використовуються в машинобудуванні. Але їх розрахунок проводиться за застарілою методикою на основі такого досить хиткого параметра як спрацюваннявкладиша підшипника. При цьому в довідковій літературі прийнято вважати, якщо матеріали вала та вкладиша однорідні, то поверхні деталей по мірі ...

Breaking the 2‐nm Barrier in Hard Disk Drives Using Monolayer Amorphous Carbon Overcoats
Advanced Materials, EarlyView.The rapid growth of AI has increased demand for large‐scale data storage, making HDDs indispensable in data centers. Increasing areal storage density is crucial, but limited by the traditional carbon overcoats (COC). Monolayer amorphous carbon (MAC) offers a superior alternative.
