Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign h...
Trap and neutralize:A new way to clean contaminated groundwater
Trap neutralize clean contaminated groundwater
2016/4/25
A team of researchers from Washington University in St. Louis have helped discover a new chemical method to immobilize uranium in contaminated groundwater, which could lead to more precise and success...
Colonial New Delhi had a cobra infestation. To get rid of it, the government offered bounties for dead cobras, inadvertently turning cobra breeding into a thriving business. When the government got wi...
Effect of Matrix Clean-Up for Aflatoxin Analysis in Corn and Dried Distillers Grains
Aflatoxin LC-MS/MS Immunoaffinity SPE

Aflatoxins are a group of highly carcinogenic mycotoxins that contaminate a wide variety of agricultural crops and have a detrimental economic impact on industries, such as corn and ethanol production...
Study on Clean Leather Deliming Process with Sulfonated Phthalic Magnesium Salt
Deliming Leather Cleaer Production Non-Ammonium Deliming Agents Sulfonated Phthalic Magnesium Salt
2011/11/23
Sulfonated phthalic magnesium salt (SPMS) was used in the leather deliming process. The deliming properties of SPMS was determined with the indicators such as the change of pH, content of NH4-N, COD o...
Comparative Investigation of Mo(CO)6 Adsorption on Clean and Oxidized Si(111) Surfaces
Molybdenum hexacarbonyl SiO2/Si(111) Interaction High-resolution elec-tron energy loss spectroscopy
2012/4/5
Mo(CO)6 adsorption on the clean, oxygen-precovered and deeply oxidized Si(111) surfaces was comparatively investigated by high-resolution electron energy loss spectroscopy. The downward vibrational fr...
A multiple-beam CLEAN for imaging intra-day variable radio sources
Methods: data analysis – Techniques: image processing – Radio continuum: general
2011/10/13
The CLEAN algorithm, widely used in radio interferometry for the deconvolution of radio images, performs well only if the raw radio image (dirty image) is, to good approximation, a simple convolution ...
MEM and CLEAN Imaging of VLBA Polarisation Observations of Compact Active Galactic Nuclei
CLEAN Imaging VLBA Polarisation Compact Active Galactic Nuclei
2011/10/10
The Maximum Entropy Method (MEM) for the deconvolution of radio interferometry images is mathematically well based and presents a number of advantages over the usual CLEAN deconvolution, such as appre...
Two questions of L. Va${\rm \check{\textbf{s}}}$ on *-clean rings
Clean ring Clean ring Regular ring Strongly clean ring Unit regular ring
2011/8/26
Abstract: A ring $R$ with an involution * is called (strongly) *-clean if every element of $R$ is the sum of a unit and a projection (that commute). All *-clean rings are clean. Va${\rm \check{s}}$ [L...
Highly Efficient Synthesis of Clean Biofuels from Biomass Using FeCuZnAlK Catalyst
Biomass Biofuel Higher alcohol Liquid hydrocarbon FeCuZnAlK catalyst
2012/4/5
Highly efficient synthesis of clean biofuels using the bio-syngas obtained from biomass gasi-fication was performed over Fe1.5Cu1Zn1Al1K0.117 catalyst. The maximum biofuel yield from the bio-syngas re...
Protecting clean critical points by local disorder correlations
Protecting clean critical points local disorder correlations
2010/11/17
We show that a broad class of quantum critical points can be stable against locally correlated
disorder even if they are unstable against uncorrelated disorder. Although this result seemingly contrad...
How to make clean separation of CMB E and B mode from incomplete sky data
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/29
We have investigated CMB E/B decomposition of incomplete sky data. Noting E and B mode decomposition operators in real space involve differentials of CMB polarization, we point out we may make clean E...
