Observation of vacuum ultraviolet laser oscillation in nitric oxide

Applied Optics, 1993
We report recent experiments that demonstrate the line tunability of a fluorine laser-pumped nitric oxide laser. Laser oscillation has been observed at 589, 234, 226, 218, 211, and 163 nm. The possibility of achieving laser oscillation on further UV and vacuum UV laser transitions in nitric oxide is discussed.

Light‐Induced Field‐Tunneling Synapses in Solution‐Processed Van Der Waals Heterostructures for Scalable, Retina‐Inspired Optical Sensing

Advanced Functional Materials, EarlyView.
A scalable, solution‐processed WSe2/ZrO2‐x van der Waals heterostructure realizes a light‐induced field‐tunneling synapse (LIFTS) that activates exclusively under bright illumination, emulating the photopic adaptation of the human retina at the device level.

Bright continuously tunable vacuum ultraviolet source for ultrafast spectroscopy

Communications Physics
Ultrafast electron dynamics drive phenomena such as photochemical reactions, catalysis, and light harvesting. To capture such dynamics in real-time, femtosecond to attosecond light sources are extensively used.

Bio‐Inspired Artificial Ionic Mechanoreceptor

Advanced Functional Materials, EarlyView.
A skin‐inspired artificial mechanoreceptor based on ionic interactions is presented for biomimetic tactile sensing. Pressure‐driven ionic redistribution within microfluidic channels generates a self‐powered electrical signal without external bias. The generated waveform exhibits mechanoreceptor‐like temporal features, including overshoot and undershoot,

Using the longitudinal space charge instability for generation of vacuum ultraviolet and x-ray radiation

Physical Review Special Topics. Accelerators and Beams, 2010
Longitudinal space charge (LSC) driven microbunching instability in electron beam formation systems of x-ray free-electron lasers (FELs) is a recently discovered effect hampering beam instrumentation and FEL operation.

Kinetics‐Controlled Architecture of Binder‐Free Organic Electrodes for Enhanced Ion Transport

Advanced Functional Materials, EarlyView.
Pulse reverse electrodeposition controls nucleation and growth to create hierarchically porous Py‐derived oligomeric electrodes with enhanced ionic accessibility and reduced transport resistance. The resulting binder‐free architectures translate these transport advantages into practical sodium‐storage functionality.
