Terpene epoxides are considered as potential primary intermediates in the synthesis of numerous green polymers including epoxy resins, polycarbonates, nonisocyanate polyurethanes and even some polyamides. In this chapter we describe recent efforts from our group to develop catalytic noncatalytic processes for terpene epoxidation using a variety oxidizing agents process intensification methods. ...

the prospects of using the biostimulation and bioaugmentation treatment for the removal of the polychlorinated biphenyl (pcbs) from contaminated sediment collected from the sewage canal in the surroundings of a former pcb manufacturing plant in slovakia is described. the eleven bacterial strains isolated in our previous work from sewage strážsky canal sediments were able to aerobically degrade ...

In spring, with the appearance of new foliage, the aromatic content of the air as measured with the gas chromatograph does not increase much, and the air is essentially free of terpenes such as a-pinene. Even when plastic bags are put around young shoots of Aster, no terpenes are detectable inside the bag until the leaves are crushed, when large amounts of terpenes are immediately released. Soo...

Microbiol. 10:524-528. 1962.-Several strains of fungi were tested for their ability to metabolize a-pinene in shake cultures. A strain of Aspergillus niger showing marked efficiency in this respect was selected for further studies. T...

The purpose of this study was to investigate the distribution of terpenes in loblolly pine with respect to the potential impact of volatile organic compound emissions during drying. The total terpene content in the inside, middle, and outside of increment core sections from twelve 40-year-old loblolly pines was determined over a period of 14 months. A method for extracting and analyzing terpene...

The purpose of this study was to investigate the effect of ultradeformable liposome components, Tween 20 and terpenes, on vesicle fluidity. The fluidity was evaluated by electron spin resonance spectroscopy using 5-doxyl stearic acid and 16-doxyl stearic acid as spin labels for phospholipid bilayer fluidity at the C5 atom of the acyl chain near the polar head group (hydrophilic region) and the ...
