Frequency stability of a wavelength meter and applications to laser frequency stabilization [PDF]

, 2015
Interferometric wavelength meters have attained frequency resolutions down to the MHz range. In particular, Fizeau interferometers, which have no moving parts, are becoming a popular tool for laser characterization and stabilization.

Ion‐Confinement‐Assisted Erasure Purifies Oxidized MXene for Reuse

Advanced Science, EarlyView.
An erasure‐purification strategy removes surface‐derived TiO2 from oxidized Ti3C2Tx MXene by ion‐confinement‐induced interfacial conversion to soluble titanates, followed by brief acid washing. The scalable process enables approximately 70% material recovery, restores electrical conductivity, and recovers functional performance, including high ...

Testing Lorentz Invariance by Comparing Light Propagation in Vacuum and Matter

, 2010
We present a Michelson-Morley type experiment for testing the isotropy of the speed of light in vacuum and matter. The experiment compares the resonance frequency of a monolithic optical sapphire resonator with the resonance frequency of an orthogonal ...

Toward Reliable Metal Halide Perovskite FETs: From Electronic Structure and Device Physics to Stability and Performance Engineering

Advanced Electronic Materials, EarlyView.
Metal halide perovskite field‐effect transistors (PeFETs) offer great promise for flexible, low‐cost, and high‐performance due to their excellent charge carrier properties. However, challenges like ion migration, hysteresis, and instability limit their performance.

Spectroscopy, Manipulation and Trapping of Neutral Atoms, Molecules, and Other Particles Using Optical Nanofibers: A Review

Sensors, 2013
The use of tapered optical fibers, i.e., optical nanofibers, for spectroscopy and the detection of small numbers of particles, such as neutral atoms or molecules, has been gaining interest in recent years. In this review, we briefly introduce the optical

Activism in the arts: Co‐researching cultural inequalities with young people during the COVID‐19 pandemic

British Educational Research Journal, EarlyView.
Abstract This paper explores the growing influence of young people's activism in UK museums and its educational implications. It draws on a five‐year collaborative programme (2019–2023) with young people of colour (16–28) in a university museum setting, focusing on a Young Collective established to address cultural inequalities.

Synergistic SnSe2@Ti3C2Tx MXene Heterostructured Separator for Highly Efficient Polysulfide Adsorption, Catalytic Redox Acceleration, and Enhanced Electrochemical Stability in Advanced Lithium–Sulfur Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A multifunctional SnSe2@MXene heterostructure coated on a separator serves as a catalytic interlayer in Li‐S batteries. This design synergistically integrates the strong polysulfide adsorption and catalytic activity of SnSe2 with the high electrical conductivity of the MXene matrix, effectively suppressing the shuttle effect and enabling long‐term ...
