Rational design of mechanically robust Ni-rich cathode materials via concentration gradient strategy

Nature Communications, 2021
Mechanical integrity issues are one of the main causes of limited long-term cycle stability for Ni-rich cathode materials. Here the authors analyse the roles of cobalt and manganese and utilise a concentration gradient design to mitigate these issues.

Quantum detector tomography of a time-multiplexed superconducting nanowire single-photon detector at telecom wavelengths [PDF]

, 2013
Superconducting nanowire single-photon detectors (SNSPDs) are widely used in telecom wavelength optical quantum information science applications. Quantum detector tomography allows the positive-operator-valued measure (POVM) of a single-photon detector ...

Passive Q-Switching of a Diode-Pumped Pr:LiYF₄ Visible Laser Using WS₂ as Saturable Absorber

IEEE Photonics Journal, 2016
Q-switched laser operation of a blue-diode-pumped Pr:LiYF4 laser is demonstrated at 640 nm for the first time by using a tungsten disulfide (WS2) nanosheet material as a saturable absorber.

Two-way tuning of structural order in metallic glasses

Nature Communications, 2020
While metallic glasses are expected to have tunable structures, these have rarely been demonstrated. Here, the authors combine temperature and pressure to show a two-way structural tuning in rare earth-based metallic glasses beyond the nearest-neighbor ...
