Plasmon-induced near-infrared fluorescence enhancement of single-walled carbon nanotubes

Ardemis Anoush Boghossian, Giulia Tagliabue, Sayyed Hashem Sajjadi, Alessandra Antonucci, Shang-Jung Wu, Theodoros Tsoulos, Amirmostafa Amirjani

Single-walled carbon nanotubes (SWCNTs) emit near-infrared (NIR) fluorescence that is ideal for optical sensing. However, the low quantum yields diminish the sensor’s signal-to-noise ratio and limits the penetration depths for in vivo measurements. In this ...

Multi-scale investigation on mechanical behavior and microstructural alteration of C-S-H in carbonated Alite paste

Karen Scrivener

Carbonation treatment is a promising option to enhance recycled concrete aggregate (RCA) quality and eventually improve concrete performance. This study investigated the multi-scale mechanical properties of calcium silicate hydrates (C-S-H) in a mature ali ...
