In the present work, we have evaluated whether isomeric C5-alkene diols (1,2-dihydroxy-2-methyl-3-butene, 1,2-dihydroxy-3-methyl-3-butene, and 1,4-dihydroxy-2-methyl-2-butene (cis + trans)), which have first been detected upon photooxidation of isoprene in the absence of NO and are known to be formed in the ambient atmosphere, can serve as precursors for the 2-methyltetrols, C5-alkene triols, a...

Ethylarsine dichloride was used during WW I as a chemical warfare agent. Residues of this chemical warfare agent and its metabolites are still present today and continue to contaminate soil and water. A gas Chromatographic method for the detection and determination of ethylarsine dichloride is shown. Six dithiols were tested as possible derivatization reagents for ethylarsine dichloride. With s...

In the present work, we have investigated the conformational isomerism and calculated the vibrational spectra of the C4 oxygenates: 3-butyne-2-one, 3-butene-2-one, 2-butanone and 2-butanol using density functional theory. The calculations are validated by comparison to structural data where available and new, experimental inelastic neutron scattering and infrared spectra of the compounds. We fi...

BACKGROUND Bone metastases are associated with increased morbidity and poor prognosis in breast cancer patients. Radium-223 dichloride is a calcium mimetic that localizes to bone, providing targeted therapy for skeletal metastasis. METHODS We investigated the mode of action of radium-223 dichloride using breast cancer cell, osteoclast, and osteoblast cultures as well as a mouse model of breas...

Abstract The oxidative dehydrogenation (ODH) of 1-butene to 1,3-butadiene was studied over a series AFe 2 O 4 catalysts, where A = Zn, Mn, Ni, Cu, Mg and Fe. catalysts were characterised by XPS, EPR spectroscopy, BET surface area analysis, Raman spectroscopy XRD. All the ferrites active for ODH gave an order activity after 80 h on-stream ZnFe > NiFe MnFe MgFe CuFe FeFe . lost significant (up...

New CO and H2O time histories were measured for 2-Methyl-1-Butene (2M1B) behind reflected shock waves. The experimental setup was developed to simultaneously obtain carbon monoxide water from the oxidation of 2M1B in 99.5% He/Ar (20% He 79.5% Ar). experiments carried out at three different equivalence ratios (? = 0.5, 1.0, 2.0) pressures temperatures ranging 1.15 atm 1.32 1414 K 1894 K, respect...
