Topology Optimization of High‐Performance Optomechanical Resonator

open access: yesAdvanced Science, EarlyView.
Compact mechanical resonators designed to operate at higher‐order modes are presented, achieving high frequencies and enhanced quality factor‐frequency (Qf) products. Using topology optimization, edge losses are reduced and damping is improved. These resonators offer strong performance in a small footprint, making them ideal for quantum transduction ...

Gravitational waves in Newton’s gravitation and criticism of gravitational waves resulting from the General Theory of Relativity (LIGO)

open access: yesҚарағанды университетінің хабаршысы. Физика сериясы, 2019
The most important conclusion from this article is that from the General Theory of Relativity do not result any gravitational waves, but just ordinary modulation of the gravitational field intensities caused by rotating of bodies.

Plant Robotics for Sustainable and Environmentally Friendly Robots: Insights from Actuation Characteristics

open access: yesAdvanced Science, EarlyView.
Plants are promising materials for building sustainable and eco‐friendly robots due to their inherent multifunctionality, with actuation playing a crucial role. This article focuses on the physical movements of plants and, from the perspective of actuation characteristics, explores representative plant species and their behaviors, the current state of ...
