Ceramic composite protection for turbine disc bursts [PDF]

, 1977
Ceramic composite turbine disc protection panels for the A300B were developed using armor technology. Analytical predictions for modifying the ballistic projectile armor system were verified by a test program conducted to qualify the rotor containment ...

Quantum partition noise of photo-created electron-hole pairs

, 2002
We show experimentally that even when no bias voltage is applied to a quantum conductor, the electronic quantum partition noise can be investigated using GHz radiofrequency irradiation of a reservoir.

Structural Color Inkjet Printing With Mie‐Resonant Silicon Nanoparticles

Advanced Materials, EarlyView.
Water‐based inks incorporating Mie‐resonant silicon nanoparticles were developed, and their application to structural color inkjet printing was demonstrated. By controlling the nanoparticle size and concentration, coloration covering a wide color gamut was achieved.

Expansion velocity of a one-dimensional, two-component Fermi gas during the sudden expansion in the ballistic regime [PDF]

, 2012
We show that in the sudden expansion of a spin-balanced two-component Fermi gas into an empty optical lattice induced by releasing particles from a trap, over a wide parameter regime, the radius $R_n$ of the particle cloud grows linearly in time.

Cellular Snowballing: Cell Adhesion and Migration Drive the Self‐Assembly of Cell‐Microgel Biohybrid Spheroids

Advanced Science, EarlyView.
A new class of biohybrid spheroids is engineered through the self‐assembly of adherent cells and extracellular matrix‐mimetic hydrogel microparticles (microgels). By mimicking a snowballing effect, this approach enables scalable formation of porous, millimeter‐scale spheroids with enhanced cell viability and molecular diffusion.

Ballistic electron spectroscopy

, 2006
We demonstrate the feasibility of ballistic electron spectroscopy as a new tool for mesoscopic physics. A quantum dot is utilised as an energy-selective detector of non-equilibrium ballistic electrons injected into a two-dimensional electron system.

Ejecta‐Modulated Bubble Dynamics Play a Dominant Role in Stone Retropulsion

Advanced Science, EarlyView.
Stone motion during laser ablation is shown to result primarily from asymmetric cavitation bubble collapse, not from ejecta recoil. This challenges long‐standing assumptions and highlights the dominant role of bubble dynamics in laser–material interactions.
