The photoactivity of methanol adsorbed on the anatase TiO2 (101) surface was studied by a combination of scanning tunneling microscopy (STM), temperature-programmed desorption (TPD), X-ray photoemission spectroscopy (XPS), and density functional theory (DFT) calculations. Isolated methanol molecules adsorbed at the anatase (101) surface show a negligible photoactivity. Two ways of methanol acti...

To investigate conformational properties of an isolated n-octadecane chain solvated in water-acetonitrile mixtures, configurational-bias Monte Carlo simulations in the isobaric-isothermal ensemble were performed at T = 323 K and p = 10 atm. The united-atom version of the transferable potentials for phase equilibria force field was used to represent n-octadecane and acetonitrile, and the TIP-4P ...

Inhibition of acetylcholinesterase (AChE) is a common treatment for early stages of the most general form of dementia, Alzheimer's Disease (AD). In this study, methanol, dichloromethane and aqueous crude extracts from 80 Traditional Chinese Medical (TCM) plants were tested for their in vitro anti-acetylcholinesterase activity based on Ellman's colorimetric assay. All three extracts of Berberis ...

Abstract: The laminar combustion characteristics of blends of isooctane and C1–C5 primary alcohols (i.e., methanol, ethanol, n-propanol, n-butanol and n-pentanol) were investigated using the spherical expanding flame methodology in a constant volume chamber at various equivalence ratios and volume fractions of alcohol. The stretch effect was removed using the nonlinear methodology. The results ...

A novel 3-5-dichlorosalicylaldehyde Schiff base chemodosimeter (compound 1) for water is designed and synthesized, and it works based on a water-triggered reaction of a Schiff base. Addition of trace amounts of water into 1 in various organic solvents leads to a fluorescence turn-on response and a simultaneous dual-channel signal modulation (both in the fluorescence and absorption spectra). Esp...

To improve the photo-catalytic degradation of salicylic acid, we reported the fabrication of ordered TiO2 nanotube arrays by a simple and effective two-step anodization method and then these TiO2 nanotubes were treated in a methanol solution under UV light irradiation. The TiO2 nanotubes prepared in the two-step anodization process showed better photo-catalytic activity than those prepared in o...

Ibuprofen, a non-steroidal anti-inflammatory drug (NSAID), is used in mild to moderate pain and fever. The rapid onset of action of ibuprofen depends on its solubility. Though ibuprofen has high membrane permeability, its solubility in aqueous media is poor (2.5mg/ml). To improve the solubility, several approaches such as solid dispersion, prodrug, inclusion complex, microencapsule etc. were do...
