Self-assembly of generative heterogeneous electric circuits
In this section, the circuit model and the self-assembly model being used are defined precisely. A full solution for the distribution of potentials as well as some properties of the models assembled are then derived using nodal analysis for a…

Targeting Entire Galaxies in Axion Search
• Physics 18, 93
Two independent teams have searched for axions using x-ray observations of entire galaxies, setting some of the strictest constraints to date on the properties of these dark matter candidates.
X-ray: NASA;…

A 100 Gb s−1 quantum-confined Stark effect modulator monolithically integrated with silicon nitride on Si
Static performance
The static electro-optic performance of the modulator was assessed in the O-band. For different bias voltages between −3 and −1 V the extinction ratio (ER) calculated with reference to the 0 V case is plotted in…

Inducing mechanical self-healing in polymer glasses
Our framework involves polymer glasses with short chains to avoid entanglement effects. Beads belonging to the same chain interact via harmonic covalent bonds. Non-consecutive beads and beads from different chains interact attractively,…

All-liquid thermal desalination and brine concentration via multichannel thermodiffusion
Theoretical framework for thermodiffusive separation
To address the first uncertainty regarding the thermodiffusive behaviour of multicomponent electrolytes, we started with the mass flux equation. For a binary system, the mass flux J under…
