Mechanical Mixtures of Me (Ni, Pd) Ce Oxides and Silica-Supported Heteropolyacids: Role and Optimal Concentration of Each Active Species in n-Hexane Isomerization [PDF]

open access: yes, 2006
Catalytic properties of silica-supported heteropolyacids (HPA) in a mechanical mixture with reduced Me–Ce oxides (Me = Ni, Pd) in n-hexane isomerization are studied.

Total Synthesis of Tulearin C

open access: yes, 2011
With the help of the smaller brother: Although alkyne metathesis will always be the little brother of alkene metathesis, it allows problems to be solved that are currently beyond reach of the more famous sibling.

Emission characteristics of CO, NOx, SO2 and indications of biomass burning observed at a rural site in eastern China [PDF]

open access: yes, 2002
Atmospheric O3, CO, SO2, and NO* y (NO* y ≈ NO + NO2 + PAN + organic nitrates + HNO3 + N2O5 + ⋯) were measured in 1999-2000 at a rural/agricultural site in the Yangtze Delta of China.

Methyl on the Bridge: 2‐Methyl Propellane as Precursor for 1,3‐Substituted 2‐Methylated Bicyclo[1.1.1]Pentanes

open access: yesChemistry – A European Journal, EarlyView.
The synthesis of 2‐methyl propellane and its conversion to various 1,2‐ and 1,2,3‐di‐ and trisubstituted bicyclopentanes is reported. Abstract Bicyclo[1.1.1]pentanes (BCPs) have emerged as isosteric replacements for mono‐ and para‐substituted benzene rings in medicinal and materials applications, involving substitution at the BCP bridgehead (1,3 ...

Computer model for refinery operations with emphasis on jet fuel production. Volume 2: Data and technical bases [PDF]

open access: yes
The FORTRAN computing program predicts the flow streams and material, energy, and economic balances of a typical petroleum refinery, with particular emphasis on production of aviation turbine fuel of varying end point and hydrogen content specifications.

(2‐Phosphinophenyl)aluminum Dichloride Complexes as Intramolecular Al/P Frustrated Lewis Pairs for Ketone, Ester, and Imine Activation

open access: yesChemistry – A European Journal, EarlyView.
Three 2‐phosphinophenylaluminum dichloride complexes were synthesized and characterized as novel intramolecular FLPs. These FLP systems exhibit high Lewis acidity and effectively activate challenging substrates including aliphatic ketones, imines, and esters. DFT analysis revealed that strain release and Al–P dynamics govern their reactivity. Abstract (

Breath pentane concentrations during labor and the effect of epidural analgesia on the pentane concentration

open access: yesInternational Journal of Obstetric Anesthesia, 1997
Increased lipid peroxidation has been observed in pregnancy and particularly in preeclampsia. Pentane, a by-product of lipid peroxidation, can be measured in exhaled breath, and its measurement is considered a non-invasive method of assessing lipid peroxidation in vivo.

Air quality in Mecca and surrounding holy places in Saudi Arabia during Hajj: initial survey. [PDF]

open access: yes, 2014
The Arabian Peninsula experiences severe air pollution, the extent and sources of which are poorly documented. Each year in Saudi Arabia this situation is intensified during Hajj, the Holy Pilgrimage of Islam that draws millions of pilgrims to Mecca.
