Here we show that the introduction of N into a carbon surface facilitates hydrogen-bonding interactions between and CO2 molecules, which accounts for superior uptake N-doped activated carbons. This new finding challenges long-held viewpoint acid–base N-containing basic functional groups acidic gas are responsible enhanced capture capacity
A series of carbide-derived carbons (CDCs) with different surface oxygen contents were prepared from TiC powder by chlorination and followed HNO3 oxidation. The CDCs characterized systematically a variety means such as Fourier transform infrared spectroscopy, X-ray photoelectron ultimate analysis, energy dispersive N2 adsorption, transmission electron microscopy. CO2 adsorption measurements showed that the oxidation process led to an increase in capacity porous carbons. Structural...
In this paper, we present a stable silver-based surface plasmon resonance (SPR) sensor using self-assembled monolayer (SAM) as protection layer and investigated its efficiency in water 0.01 M phosphate buffered saline (PBS). By simulation, SPR has better performance field enhancement penetration depth than that of gold-based sensor, which are 5 1.4 times, respectively. To overcome the instability bare silver film investigate protected layer, SAM 11-mercapto-1-undecanol (MUD) was used layer....

Monitoring glucose levels is one of the main diagnostic methods for preventing and treating diabetes. Conventionally monitoring blood through a finger-stick procedure brings pain. It essential to develop biosensors low concentration detection in non-invasive samples. In this paper, tilted fiber grating based localized surface plasmon resonance (LSPR) biosensor ultrasensitive has been demonstrated. The was fabricated by immobilization Au nanoparticles (AuNPs) onto an excessively (Ex-TFG)...
Arrays of ordered nanorods are special interest in many fields. However, it remains challenging to obtain such arrays on conducting substrates a facile manner. In this article, we report the fabrication highly and vertically standing nanorod both metals semiconductors Au films indium tin oxide glass without an additional layering. approach, following simple hydrophilic treatment anodic aluminum (AAO) membrane substrates, AAO was transferred onto modified with excellent adhesion....
Abstract A stretchable and steady performance of human–machine interfaces localized tactile perception is a broad concerning problem. Existing sensors touchpads claim to be for location detection failing offer with uniformity during inevitable flexible movements, as well linearity. The fabrication highly transparent touch sensor, which made hydrogels PDMS, could simultaneously precisely determine pressure while being stretched or unstretched. It noteworthy that the sensor introduces new...
