Fingerprinting Superconductors by Disentangling Andreev and Quasiparticle Currents Across Tunable Tunnel Junctions

Small, EarlyView.
Tunneling Andreev reflection spectroscopy leverages the exponential sensitivity of tunneling current to distinguish between a variety of superconducitng order parameters. Here it is shown that the additivity of excess decay rate enables clear separation of Andreev and quasiparticle currents, fingerprinting the existence of sign changing superconducting

“White and Clear” (WaC): A tunable hydrophilic tissue clearing strategy for multi‐species 3D imaging

VIEW, EarlyView.
Optical tissue clearing methods help scientists make tissues transparent to image structures deep inside organs in 3D, but many existing techniques are limited in performance and difficulty. In this study, we developed an optimized clearing method called WaC (White and Clear), which improves upon existing techniques by combining efficient tissue ...

Experimental Demonstration of Superradiant Amplification of Ultra-Short Laser Pulses in a Plasma [PDF]

, 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.

Four‐dimensional immuno‐mechanobiomaterials: Dynamic material cues that program host response to prevent fibrosis and enable regeneration

VIEW, EarlyView.
Dynamic immuno‐mechanobiomaterials with time‐programmed mechanical adaptation orchestrate host responses through precise mechanotransduction and immune‐stromal regulation. These adaptive biomaterials minimize mechanical mismatch, attenuate the forign dy response and fibrosis, promote angiogenesis and controlled extracellular matrix remodeling, and ...
