High-quality-factor viscoelastic nanomechanical resonators from moiré superlattices
Large TBG drumhead resonators
The TBG drumhead nanomechanical resonators are prepared by a ‘tear-and-stack’ method using both wet and dry transfer techniques (see Methods). Supplementary Table S1 presents our devices based on their size,…

Multi-DoF AlN-on-SOI BAW MEMS resonators with coated ZIF-8 for gas sensing application
Sensing mechanism
A single BAW resonator system can be modeled as a mass-spring-damper system and a representation that also extends to 2 and 3-degree-of-freedom (DoF) resonating devices30, as illustrated in Fig. 1. Figure 1a shows the proof mass…

Sub-pA dark current infrared photodetection enabled by polarized water-intercalated heterojunctions
Designing ultra-thin polar barrier structures
As illustrated in Fig. 1a, b, realizing an ideal unipolar barrier nBn structure solely by engineering the band structure via 2D layer stacking presents a significant challenge. The core difficulty…

Enhancing xanthan hydrogels for water shutoff treatment in sandstone oil reservoirs through core flooding and CCD approach
Performance of hydrogel
While confirming the relatively low stability of xanthan-based hydrogels that tend to break over time, it has been tried to investigate the factors that can increase the strength and stability of xanthan-based hydrogels and…
