Microphysics of Cosmic Ray Driven Plasma Instabilities
, 2013 Energetic nonthermal particles (cosmic rays, CRs) are accelerated in supernova remnants, relativistic jets and other astrophysical objects. The CR energy density is typically comparable with that of the thermal components and magnetic fields.

Advanced Materials, EarlyView.A fully flexible ion‐gel‐gated graphene‐channel transistor driven by a triboelectric nanogenerator enables self‐powered tactile sensing and synaptic learning. Mimicking spike‐rate‐dependent plasticity, the device exhibits frequency‐selective potentiation and depression, supporting rate‐coded neuromorphic computation even under flex.

Plasma instabilities near Mars
, 2006 Meeting abstract from the CDROM, #2338It has been suggested in the literature that the Kelvin-Helmholtz instability can be responsible for significant ion loss at Mars through the detachment of ionospheric plasma clouds Clouds of detached ionospheric ...

Experimental Demonstration of Superradiant Amplification of Ultra-Short Laser Pulses in a Plasma
, 2005 A novel amplifications scheme for 20-30-fs laser pulses has been demonstrated. The signal pulses are amplified in a plasma by few picosecond long, counterpropagating pump pulses.

Numerical investigation of plasma-driven superradiant instabilities
, 2020 International audiencePhotons propagating in a plasma acquire an effective mass μ, which is given by the plasma frequency and which scales with the square root of the plasma density.

Advanced Materials, EarlyView.Oxygen‐releasing hydrogels are widely used to support cell survival in 3D cultures and to promote wound healing. However, incorporating catalase to convert H2O2 into O2 often generates additional oxygen bubbles, leading to material instability which rarely addressed.

Some Considerations and Techniques for the Predictive Simulation of Global Instabilities in Tokamaks
, 2010 This is a write-up of a lecture given at the Fourth ITER International Summer School held at the IFS, U. Texas in June 2010. A simple rigid plasma model is used to show that axisymmetric plasma instabilities (in two-dimensions) will occur on a resistive ...

Advanced Materials, EarlyView.An Aloe‐pinspired droplet electricity generator (A‐DEG) overcomes the limited energy collection zone of conventional DEGs by guiding impact droplets through a channeling midrib and artificial cuticle. The channeling midrib induces uni‐directional droplet spreading, while the artificial cuticle on the midrib further reinforces this behavior through its ...
