High Center‐of‐Mass, Multi‐Legged Soft Robots Powered by Geometrically Encoded Liquid Crystal Elastomer Arc Appendages

open access: yesAdvanced Materials, EarlyView.
Inspired by the octopus and the golden wheel spider, soft robots with liquid crystal elastomer arc fibers as appendages are fabricated to transcend surface constraints through an elevated center of mass and minimal contact footprints. By leveraging curvature‐encoded deformation‐recovery cycles, these robots exhibit contractile, torsional, and flexural ...

Impact of Automatic Transmission on Vehicles Exploatation Caracteristics [PDF]

open access: yes, 2016
Transmisija vozila jedan je od najvažnijih sustava na cestovnim motornim vozilima. Njezina zadaća je snagu motora transformirati i dovesti do pogonskih kotača. No mjenjač kao dio transmisije ima najveću ulogu u tom procesu.

Universal Adaptive Automatic Reclosure Techniques For Transmission Lines

open access: yes, 2013
A fault on a transmission line leads to opening of both ends circuit breakers to isolate the fault from rest of the power system. Majority of faults on a transmission line are temporary as the arc extinguishes itself after certain time.

Engineering Layered Magnetic Hydrogels for Cell Placement via Shear and Magnetic Field‐Induced Assembly

open access: yesAdvanced Materials, EarlyView.
Magnetic particles are organized into layered architectures by combining shear flow and magnetic fields, with the resulting structures governed by appropriate Mason numbers. The programmed assemblies provide spatial guidance for cell placement, linking field‐controlled self‐assembly, flow‐induced structuring and biological organization.

Ambient Light‐Activatable Luminescent Particle‐Embedded Conformal Patch for Photochemical Tissue Bonding and Photobiomodulated Healing

open access: yesAdvanced Materials, EarlyView.
We report a wearable photonic patch integrating room light‐ and sunlight‐activatable luminescent particles (RSLPs) for both photochemical tissue bonding and photobiomodulation. RSLPs harvest ambient light and emit red luminescence to drive chlorin e6–mediated collagen crosslinking.
