In this work, we studied indium tin oxides (ITOs) modified with dendrimer-encapsulated Pt nanoparticles (Pt DENs) to develop efficient p-aminophenol (p-AP) redox cycling platforms. The ITO surfaces were modified via electro-oxidative grafting of the

Enhanced electrochemiluminescence (ECL) of luminol was reported with the use of dendrimer-encapsulated Au nanoparticle (Au DEN)-modified ITOs in the presence of hydrogen peroxide, which was applied for sensitive ECL-based electroanalysis of hydrogen

The intermediates of thermal decomposition of 1,3-disilabutane (SiH 3 CH 2 SiH 2 CH 3 , DSB) to form SiC on Si(1 0 0) surface were in situ investigated by reactive ion scattering (RIS), temperature programmed reactive ion scattering (TPRIS), temperat

We have investigated adsorption and desorption condition of atomic hydrogen on single-walled nanotubes (SWCNTs) using ultraviolet photoelectron spectroscopy (UPS) and thermal desorption spectroscopy (TDS). The SWCNTs were made by the high pressure ca

Influence of oxygen adsorption on CO chemisorption behavior over W(110) surfaces was studied using valence band spectra and thermal desorption spectroscopy (TDS). In the absence of O, CO formed a tilted and a vertical structure at 120 K on W(110). In

This study examined the adsorption of CO on a Mo(110) surface by Thermal Desorption Spectroscopy (TDS) and synchrotron-radiation based photoemission spectroscopy (SRPES). CO desorption was observed at approximately 400 K (α-CO) and > 900 K (β-CO).

Adsorption structure of CO on W and Mo at above ∼800 K (β-CO) has been extensively studied in the history of surface science. Most of the previous studies concluded that CO is dissociated in the β-CO, and a tilted structure plays a role as a prec

Hydrogen storage in single-walled carbon nanotubes (SWCNTs) was investigated by using a dual quartz-crystal microbalance (QCM). The chamber pressure can be adjusted from 10 - 9 torr up to 1 MPa. The dual QCM decreases the frequency fluctuations that
