Highly Coherent Femtosecond Electron Pulses for Ultrafast Transmission Electron Microscopy [PDF]
We describe the implementation and detailed characterization of a laser-triggered field-emitter electron source integrated into a modified transmission electron microscope. Highly coherent electron pulses enable high resolution ultrafast electron imaging

Direct and remote induced actuation in artificial muscles based on electrospun fiber networks
The present work reports a new configuration of soft artificial muscle based on a web of metal covered nylon 6/6 micrometric fibers attached to a thin polydimethylsiloxane (PDMS) film.

Effect of geometry, anisotropy and composition on the third-order optical nonlinearities of multilayer hyperbolic metamaterials -INVITED [PDF]
Quantum technologies require advanced optical metamaterials whose properties can be tailored and controlled as desired. Hyperbolic metamaterials have great potential for applications in nonlinear nanophoton-ics, such as all-optical switching, optical ...

An extended computational approach for point-defect equilibria in semiconductor materials
Concentrations of intrinsic and extrinsic point defects in crystalline materials with a bandgap are typically calculated in a constant-μ approach from defect formation energies based on density functional theory. In this work, calculations of thermal and

Figure of merit for design of ε-near-zero metamaterials with enhanced Kerrtype nonlinearities [PDF]
Metamaterials are artificial media designed to display properies going beyond those of ordinary materials. Particularly interesting are ε-near-zero (ENZ) media with real part of the permittivity going to zero in a certain spectral range.

Quantitative prediction of grain boundary thermal conductivities from local atomic environments
Connecting grain boundary structures to macroscopic thermal behaviour is an important step in materials analysis and design. Here the authors develop a physical model combined with a machine-learning approach to accurately predict thermal conductivities ...
