Recent Trends in the Production, Combustion and Modeling of Furan-Based Fuels
There is growing interest in the use of furans, a class of alternative fuels derived from biomass, as transportation fuels. This paper reviews recent progress in the characterization of its combustion properties.

SYNTHESYS OF A FUNCTIONALIZED TETRAHYDROFURAN FRAGMENT THROUGH BROMINATION-CYCLIZATION OF A CONJUGATED DIENE [PDF]
Conjugate 1,4-addition of N-bromosuccinimide (NBS) to a diene system, possessing a suitable oxygen functionality, leads to functionalized tetrahydrofuran derivatives, which can be further derivatized into different synthetic targets.

QSTR Models in Dioxins and Dioxin-like Compounds Provide Insights into Gene Expression Dysregulation
Polychlorinated dibenzo-p-dioxins and polychlorinated dibenzo-p-furans (PCDD/Fs) are a group of organic chemicals containing three-ring structures that can be substituted with one to eight chlorine atoms, leading to 75 dioxin and 135 furan congeners.

Chemotaxis to Furan Compounds by Furan-Degrading Pseudomonas Strains [PDF]
ABSTRACT Two Pseudomonas strains known to utilize furan derivatives were shown to respond chemotactically to furfural, 5-hydroxymethylfurfural, furfuryl alcohol, and 2-furoic acid. In addition, a LysR-family regulatory protein known to regulate furan metabolic genes was found to be involved in regulating ...

Pyrolysis of furan in a microreactor [PDF]
A silicon carbide microtubular reactor has been used to measure branching ratios in the thermal decomposition of furan, C4H4O. The pyrolysis experiments are carried out by passing a dilute mixture of furan (approximately 0.01%) entrained in a stream of helium through the heated reactor.
