  • Retention Indices for Frequently Reported Compounds of Plant Essential Oils
    Retention Indices for Frequently Reported Compounds of Plant Essential Oils V. I. Babushok,a) P. J. Linstrom, and I. G. Zenkevichb) National Institute of Standards and Technology, Gaithersburg, Maryland 20899, USA (Received 1 August 2011; accepted 27 September 2011; published online 29 November 2011) Gas chromatographic retention indices were evaluated for 505 frequently reported plant essential oil components using a large retention index database. Retention data are presented for three types of commonly used stationary phases: dimethyl silicone (nonpolar), dimethyl sili- cone with 5% phenyl groups (slightly polar), and polyethylene glycol (polar) stationary phases. The evaluations are based on the treatment of multiple measurements with the number of data records ranging from about 5 to 800 per compound. Data analysis was limited to temperature programmed conditions. The data reported include the average and median values of retention index with standard deviations and confidence intervals.

This article is published with open access at Springerlink.com Abstract: In recent years, a new 2D-layered material—black phosphorus (BP)—has been a rising star after the era of graphene owing to its high charge carrier mobility, tunable direct bandgap and unique in-plane anisotropic structure. With the development of the synthesis and modification methods of BP, its extensive applications, e.g., transistors, batteries and optoelectronics have emerged. In order to explore its full potential, research into the tribological properties of BP 2D-layered materials such as lubrication additives and fillers in self-lubricating composite materials would be not only of high scientific value but also of practical significance. In this work, recent advances on the friction and lubrication properties of BP nanosheets made by our group, including the micro-friction properties, the lubrication properties of BP nanosheets as water-based and oil-based lubrication additives, and the friction and wear of BP/PVDF composites will be presented. Finally, the future challenges and opportunities in the use of BP materials as lubricants will be discussed. Keywords: black phosphorus; two-dimensional (2D) material; lubricant additive; self-lubricating composite materials; friction 1 Introduction certain period owing to the finite lubricant thickness, and it can be easily affected by the environment.

It is the element with atomic number 8 and represented by the symbol 'O'. It is a highly reactive non-metallic period 2 element that readily forms compounds (notably oxides) with almost all other elements. Oxygen is the third most abundant element in the universe by mass after hydrogen and helium. Diatomic oxygen gas constitutes 21% of the volume of air. Water is the most familiar oxygen compound. OXYGEN HISTORY Oxygen makes up 21% of the atmosphere we breathe, but it was not discovered as a separate gas until the late i8th century. Oxygen was independently discovered by Carl Wilhelm Scheele, in Uppsala in 1773 or earlier and by Joseph Priestley in Wiltshire, in 1774. The name oxygen was coined in 1777 by Antoine Lavoisier.
