A 70 MPa silicon resonant pressure microsensor with resonators supported by micro beams based on volume compressed sensing
Structural design and sensing principle
Figure 1a shows the overall structural design of the microsensor, which mainly consists of two parts: a SOI wafer and a silicon wafer as cap. Micro-beam supports and resonators are placed on the device layer…

Strain-tuning for superconductivity in La3Ni2O7 thin films
Epitaxial thin film
We fabricated La3Ni2O7 thin films on three substrates using pulsed-laser deposition (see Methods for details). To tune the strain, we selected SrTiO3 (001) with (aSTO = 3.905 Å), NdGaO3 (001)pc (aNGO = 3.855 Å)…

Giant activity-induced elasticity in entangled polymer solutions
Model: active entangled polymer simulations
We perform 3D Brownian dynamics simulations of highly-entangled polymer solutions of N self-propelled, flexible polymer chains using the bead-spring model28. Each chain consists of Np monomers with…
