A Proof‐of‐Principle Design for Through‐Space Transmission of Unidirectional Rotary Motion by Molecular Photogears**

open access: yesChemistry – A European Journal, Volume 30, Issue 2, January 8, 2024.
A stereochemical approach to transmitting the directional double‐bond rotary motion of light‐driven molecular motors through space onto a remote single‐bond axis is put forth and successfully tested by means of quantum‐chemical modeling. A key result in the assessment of the approach is that the desired photogearing process is favorable compared to the

Topology Optimization of Spiral Bevel Gear for Differential

open access: yesInternational Journal of Innovative Technology and Exploring Engineering, 2020
The Spiral Bevel gear used in differential should be enough stiff to resist the vibrations and stresses encountered during its operation. The gear must also have sufficient strength to bear the bending stresses occurring in the differential assembly in its course of operation.
