“…The larger the displacement in BASs signals after the saturation step, the higher the acid strength. These resonance displacements induced by adsorption have been measured for a number of zeolites (H-X; HeY; Al,Na-X; Al,LaeY; H,NaeY; Al,NaeY; H-MOR; and H-USY), showing strong correlations with results afforded from other methods [65,107,109].…”

“…1f, a low-field shoulder appears at 9 ppm. Signals at a very similar chemical shift were observed upon interaction of acetonitrile with Brønsted acidic bridging OH groups (SiOHAl) in zeolites H,Na-Y [16,20], which is originated by hydrogen bondings of zeolitic SiOHAl groups with the nitrile. In Fig.…”

The authors use elastomeric polydimethylsiloxane substrates to strain single-walled carbon nanotubes and modulate their electronic properties, with the aim of developing flexible materials that can sense their local strain. They demonstrate micron-scale nanotube devices that can be cycled repeatedly through strains as high as 20% while providing reproducible local strain transduction via the device resistance. They also compress individual nanotubes and find that they undergo an undulatory distortion with a characteristic spatial period of 100-200 nm, in agreement with continuum elasticity theory. These could potentially be used to create quantum-well superlattices within individual nanotubes, enabling novel devices and applications.
