conclusions the uv/zno system has been found an effective process with 90.2% cod removal and 95.6% dye removal after 50 minutes treatment. materials and methods in this work, zno catalyst and mercury lamp (uv-c, 254 nm) have been applied for removal of the c.i. sulphur red 14 dye from aqueous environments. the influence of various parameters such as the amount of zno, initial dye concentration,...

The molecular structure and hydrogen bonding of ethylene glycol (EG) and EG-water mixtures in the liquid phase were studied by using near-infrared (NIR) spectroscopy. The spectra were evaluated using a two-dimensional (2D) correlation approach, moving-window 2D correlation analysis and chemometric methods. The minor changes for the CH stretching bands indicate that the structures of pure liquid...

Liquid water has rich thermodynamic behavior over a range of temperatures and pressures[1]. Models of water used in protein folding simulations must be fast and reflect the underlying hydrogen bond network accurately. Although greatly simplified, current models of water can account for more then 99% of the CPU time during numerical simulations[2]. Current models assume simple additivity of free...

Combining density-functional theory and thermodynamics we compute the phase diagram of surface structures of rutile RuO2(110) in equilibrium with water vapor in the complete range of experimentally accessible gas phase conditions. Through the formation of hydroxyl or water-like groups, already lowest concentrations of hydrogen in the gas phase are sufficient to stabilize an oxygen-rich polar ox...

Water ice is abundant both astrophysically, for example in molecular clouds, and in planetary systems. The Kuiper belt objects, many satellites of the outer solar system, the nuclei of comets and some planetary rings are all known to be water-rich. Processing of water ice by energetic particles and ultraviolet photons plays an important role in astrochemistry. To explore the detailed nature of ...

Objectives This study aimed to investigate the protective effects of hydrogen-rich water (HW) intake on renal injury in neonatal rats with high oxygen loading.
