Achieving High Spatial Resolution Transmission Electron Microscopy Studies in Closed Liquid Cells

open access: yesAdvanced Materials, EarlyView.
Achieving high spatial resolution is important for resolving nanoscale dynamic processes and structural transformations in liquid environments, yet remains challenging in liquid cell transmission electron microscopy (LCTEM). This review highlights key strategies, including mitigating membrane bulging, displacing or redistributing local liquid ...

Giant Nonequilibrium Valley Control via Spin‐Selective Hot‐Carrier Transfer in an Antiferromagnetic van der Waals Stack

open access: yesAdvanced Materials, EarlyView.
Spin‐selective hot‐carrier transfer across CrSBr/WSe2/CrSBr interfaces couples the continuously tunable magnetic configuration of antiferromagnetic CrSBr to the valley degrees of freedom of monolayer WSe2, enabling giant nonequilibrium valley control and magnetic‐state‐dependent reversal of circularly polarized emission.

Optical Hybrid Switching – Combined Optical Burst Switching and Optical Circuit Switching

2004
In this paper, we propose a new optical hybrid switching technique which combined Optical Burst Switching (OBS) and Optical Circuit Switching (OCS) using flow classification. In particular, this switching technique classifies incoming IP traffic flows into short-lived and long-lived flows for Quality of Service (QoS) provisioning according to traffic ...

Optical Packet Switching and Optical Burst Switching

2020
Optical transmission has long been the established choice for nonwireless data transmission spanning distances longer than a few tens of meters, due to its high bandwidth and electromagnetic noise immunity. Most current high-bandwidth networks are essentially a group of fiber-optic links connected by nodes whose function is to forward incoming data to ...

MEMS optical switches

IEEE Communications Magazine, 2001
Leveraging MEMS's inherent advantages such as the batch fabrication technique, small size, integrability, and scalability, MEMS is positioned to become the dominant technology in optical crossconnect switches. MEMS optical switches with complex movable 3D mechanical structures, micro-actuators, and micro-optics can be monolithically integrated on the ...
