There are a lot of research programs focusing on the development new solvents for carbon dioxide capture. The most important priority should be reducing energy consumption needed at regeneration step, but minimizing solvent degradation and its corrosivity is also considered as priority. In this research, aqueous blends 2-amino-2-methyl-1-propanol (AMP: 1 kmol·m−3) 1-amino-2-propanol (MIPA: 0.1–...

A Rh porphyrin on carbon black was shown to catalyze the electro-oxidation of several aliphatic alcohols (ethanol, 1-propanol, and 2-propanol) and benzyl alcohols. The overpotentials for alcohol oxidation were very low. The reaction mechanism and substrate specificity are discussed.

The application of Raman spectroscopy to characterize natively unfolded proteins has been underdeveloped, even though it has significant technical advantages. We propose that a simple three-component band fitting of the amide I region can assist in the conformational characterization of the ensemble of structures present in natively unfolded proteins. The Raman spectra of alpha-synuclein, a pro...

RATIONALE Electrospray ionization mass spectrometry (ESI-MS)-based techniques commonly used in oligonucleotide analyses are known to be sensitive to alkali metal adduct formation. Adducts directly impact the sensitivity of MS-based analyses as the available charge is distributed across the parent peak and adduct(s). The current study systematically evaluated common liquid chromatography (LC) co...

Particulate matter (PM) is emitted from a range of combustion sources, can vary greatly in properties, and able to penetrate deep into the human lungs, conveying carcinogenic PAHs present on particle surface. Alcohol based biofuels have been shown potentially reduce PM emissions when displacing fossil fuels. To improve understanding influence fuel bound oxygen relative toxicity PM, this paper i...

The disposition of [(14)C]-labeled n-butyl glycidyl ether (BGE, 3-butoxy-1,2-epoxypropane) was studied in rats and mice. The majority of a single p.o. dose (2-200 mg/kg) was excreted in urine (rats, 84-92%; mice, 64-73%) within 24 h. The rest of the dose was excreted in feces (rats, 2.6-7.7%; mice, 5.3-12%) and in expired air as (14)CO(2) (rats, 1.5%; mice, 10-18%), or remained in the tissues (...

In this study, CeO2 hollow spherical nanoparticles, CeO2/SiO2 @ CeO2 core/shell composites,and hollow CeO2/SiO2 sensors were synthesized and their microstructures were researched byFT-IR, XRD, FESEM, EDX and BET analyses. The peaks observed in the FT-IR spectra of the synthesizedsamples corresponded to Ce-O stretching vibration (ca. 566 cm-1) and O-Si-O bendingvibration (ca. 470 cm-1). XRD diff...
