Initial Distance‐Dependent Mean Force Drives Synaptic Vesicle Motion Toward Fusion Sites in Stimulated Hippocampal Neurons

open access: yesAdvanced Science, EarlyView.
Synaptic vesicle (SV) motion and exocytosis dynamics in the presynaptic terminals of live neurons are intimately linked to synaptic transmission during neuronal activity. In this work, it is revealed that, during electrical stimulation, SVs located farther from their fusion sites exhibit greater straightness and experience larger mean forces directed ...

Feline‐Inspired Robot Enabled by Combustion‐Driven Actuators for Agile Motion and High‐Payload Obstacle Traversal

open access: yesAdvanced Science, EarlyView.
Inspired by nature's competitive maneuvers, this study introduces a combustion‐driven soft actuator that powers a multi‐modal “Jump‐and‐Fly Catbot” (JFC). With millisecond response, high‐force output (over 70 times its weight) and precise control (error within 5%), the robot can jump, fly, hover, and escape from challenging environments, achieving ...

Analysis of light weight natural fiber composites against ballistic impact: A review

open access: yesInternational Journal of Lightweight Materials and Manufacture, 2023
The main factors in the ballistic impact mechanism, an incredibly complicated mechanical process, are the target material's thickness, toughness, strength, ductility, density, and projectile parameters. Creating resilient, high-strength, and high-modulus

Anomalous Ballistic Transport in Disordered Bilayer Graphene: Dimer Vacancies induced Dirac Semimetal

open access: yes, 2015
We report anomalous quantum transport features in bilayer graphene in presence of a random distribution of structural vacancies. By using an efficient real-space Kubo-Greenwood transport methodology, the impact of a varying density of dimer versus non ...

Heterogeneous Integration of Flipped Oxide Heterostructure Membranes for Nanoelectronics

open access: yesAdvanced Electronic Materials, EarlyView.
A flipped electronically reconfigurable STO/LAO freestanding membrane is demonstrated and integrated with various host platforms via controlled transfer. Using ultra‐low‐voltage electron‐beam lithography, conductive nanostructures are created at the buried STO/LAO interface. This novel approach enables heterogeneous integration of flipped complex oxide
