RELATIONSHIP BETWEEN ROLLING AND SLIP RESISTANCE IN ROLLING BEARINGS
Nauka ta progres transportu, 2016 Purpose. About one of the causes of slip rolling is known from the second half of the 19th century, it was believed that the slip resistance appears at the place of contact due to different speeds on the arc of contact.

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.

Advanced Materials, EarlyView.Device‐level zinc batteries are energy‐limited by the mass/volume of inactive components, while lean‐electrolyte operation triggers interfacial water depletion and unstable kinetics. Here we elucidate lean‐failure mechanisms and develop a COF@PAN functional separator that regulates hydrogen‐bonding networks to manage water activity and accelerate ...
