Oxidation of single-walled carbon nanotubes in dilute aqueous solutions by oz…
Abstract. A clean and simple wet chemical process using dilute aqueous ozone (O3) solution with or without ultrasound (US) was used to functionalize single-walled carbon nanotubes (SWCNTs). Both O3 and O3/US treatments greatly increased the stability of SWCNTs in water. Results of X-ray photoelectron spectroscopy (XPS) showed that the surface oxygen to carbon atomic ratio increased by more tha…

Correlating hydrogenation activity with binding energies of hydrogen and cycl…
Abstract. This study used a combination of density functional theory (DFT) and temperature-programmed desorption (TPD) to determine trends in the hydrogenation activity of cyclohexene on several bimetallic surfaces prepared by modifying Pt(111) with 3d transition metals (Fe, Co, Ni, and Cu). The hydrogen binding energy (HBE) on the subsurface Pt-3d-Pt(111) “sandwich” structures was sign…

A DFT study of the chain growth probability in Fischer–Tropsch synthesis
Abstract. The chain growth probability (α value) is one of the most significant parameters in Fischer–Tropsch (FT) synthesis. To gain insight into the chain growth probability, we systematically studied the hydrogenation and C–C coupling reactions with different chain lengths on the stepped Co(0001) surface using density functional theory calculations. Our findings elucidate the relati…

Effect of Cage Charges on Multiphoton Absorptions: First-Principles Study on …
A combined method of the time-dependent density functional theory (TDDFT) and sum-overstate (SOS) formula was implemented to model multiphoton absorption spectra, including two-photon absorption (2PA) and three-photon absorption (3PA), of Sc2C2@C68 and Sc3N@C68 endohedral metallofullerenes (EMFs). This method has been proved to be effective by comparisons between the calculated and experimen…

Fibre digestion potential in sugarcane across the harvesting window
The objectives of this study were to determine the proportion of indigestible neutral detergent fibre (iNDF) in the neutral detergent fibre (NDF) fraction of sugarcane,to estimate changes in NDF digestibility (NDFD) during the harvesting window and to predict sugarcane digestibility based on its fibre fractions. Whole plants of the IAC86-2480 and IAC93-3046 varieties were collected during the …
