Fossils air to form
2019/11/15
Some of the world's most exquisite fossil beds were formed millions of years ago during time periods when Earth's oceans were largely without oxygen.That association led paleontologists to believe tha...

Research on Compression and Rebounding of the Zoom Air in Sport-Shoes
Compression Energy Return Rebounding Shock Absorption Sport-Shoe Zoom Air
2011/12/21
Today, the zoom air was widely used in top grade sport-shoes. Firstly, the function of zoom air, including shock absorption, energy return, light quantization and ornament results were introduced. Sec...

utdoor radon seasonal and spatial variations
2017/4/12
Atmospheric radon concentrations were monitored from autumn 2004 to winter 2007 in an abandoned coal mining
area of SW Poland that contained various bedrock uranium contents, ranging from 1 to 8 ppm....
Determination of Henry’s law constant of halocarbons in seawater and analysis of sea-to-air flux of iodoethane (C2H5I) in the Indian and Southern oceans based on partial pressure measurements
solubility equilibrator volatile organic compounds
2017/4/12
The sea-to-air flux of C2H5I (iodoethane) in the Indian Ocean and the Southern Ocean was estimated from the Henry’s
law constant (KH) and the measured partial pressures of C2H5I in surface seawater a...
Helium in old porcelain: The historical variation of the He isotopic composition in air
helium isotopes atmosphere porcelain anthropogenic fluxes Industrial Revolution
2017/8/9
It is still debated whether there is a variation of the atmospheric 3He/4He ratio, due to the anthropogenic release of radiogenic 4He contained in fossil fuels, in modern era. In this study, we measur...

Properties of As and S at NiAs, NiS, and Fe1-xS surfaces, and reactivity of niccolite in air and water
NiAs NiS reactivity of niccolite air and water X-ray photoelectron spectroscopic
2012/3/31
Niccolite (NiAs), NiS (high temperature form), and pyrrhotite (Fe S) are structurally related,
with sulfur and arsenic sixfold coordinated. Their fracture or cleavage necessarily produces sur-
hybri...
The {l014} surfaces ofoptical quality calcite (Iceland spar) wereexamined in air using scanning force microscopy (SFM) immediately after cleavage and during the hours and days that followed. In the ab...
Vapor-Phase Sorption and Polymerization of Phenols by Smectite in Air and Nitrogen
Adsorption Mass spectrometry Nitrogen Phenols Pollution Polymerization Smectite
2012/1/13
Reactions of smectite with phenols were investigated to understand the role of clay minerals in abating transport of these organic pollutants to ground water. Sorption of o-methylphenol, o-chloropheno...
