The influence of paraffin wax addition on the isothermal crystallization of LLDPE

12-Sep-2016 | Thandi P. Gumede, Adriaan S. Luyt, Ricardo A. Pérez‐Camargo, Alejandro J. Müller, Journal of Applied Polymer Science, 2016

ABSTRACT The influence of paraffin wax addition on the isothermal crystallization kinetics of linear low density polyethylene (LLDPE) was studied in a temperature range where the wax was always in the molten state and could be considered a solvent for LLDPE. The LLDPE/wax blends were prepared ...

Variations of leaf cuticular waxes among C3 and C4 Gramineae herbs

26-Aug-2016 | Yuji HE, Jianhua GAO, Na GUO, Yanjun GUO, Chemistry & Biodiversity, 2016

Abstract Modern C4 plants are commonly distributed in hot and dry environments whereas C3 plants predominate in cool and shade areas. As the outmost of plant surface, the deposition and chemical composition of cuticular waxes vary under different environmental conditions. However, whether such ...

Molecules, Vol. 21, Pages 1039: Insecticidal Properties of a Highly Potent Wax Isolated from Dolichandra cynanchoides Cham

11-Aug-2016 | Díaz Napal, Georgina ; Carpinella, María C.; Palacios, Sara M., Molecules, 2016

Bioassay-guided fractionation of an ethanolic extract of the aerial parts of Dolichandra cynanchoides Cham. (Bignoniaceae) led to the isolation of a natural wax with anti-insect activity against Spodoptera frugiperda (Noctuidae) and Epilachna paenulata (Coleptera). The compound was identified ...

Pine Needles for the Screening of Perfluorinated Alkylated Substances (PFASs) along Ski Tracks

09-Aug-2016 | Mária Chropeňová; Pavlína Karásková; Roland Kallenborn; Eva Klemmová Gregušková; Pavel Čupr, Environmental Science & Technology, 2016

Perfluorinated alkylated substances (PFASs) are today considered persistent, toxic, and bioaccumulative contaminants. Perfluorooctansulfonate (PFOS) and perfluorooctanoic acid (PFOA) are currently listed as priority substances under the UNEP global convention for the regulation of POPs. A ...

Geographically‐related variation in epicuticular wax traits of Pinus nigra populations from Southern Carpathians and Central Balkans – taxonomic considerations

07-Jun-2016 | Zorica Šarac, Bojan Zlatković, Snežana Jovanović, Gordana Stojanović, Petar D. Marin, Chemistry & Biodiversity, 2016

Abstract The chemical composition of epicuticular waxes of nine populations from three Pinus nigra J.F. Arnold subspecies (determined as ssp. nigra, ssp. banatica (Borbás) Novák, and ssp. pallasiana (Lamb.) Holmboe), from Southern Carpathians and central Balkan Peninsula were analyzed using ...

Compositae Plants Differed in Leaf Cuticular Waxes between High and Low Altitudes

02-May-2016 | Na Guo, Jianhua Gao, Yuji He, Yanjun Guo, Chemistry & Biodiversity, 2016

Abstract We sampled eight Compositae species at high altitude (3482 m) and seven species at low altitude (220 m), analyzed the chemical compositions and contents of leaf cuticular wax, and calculated the values of average chain length (ACL), carbon preference index (CPI), dispersion (d), ...

Short‐Term Water Deficit Changes Cuticular Sterol Profile in the Eggplant (Solanum melongena)

29-Apr-2016 | Łukasz P. Haliński, Piotr Stepnowski, Chemistry & Biodiversity, 2016

Abstract Crop irrigation uses a majority of a total world water supply, in the same time displaying low efficiency. As the expected future water requirements are higher than the current ones, there is a risk of a growing deficit of water for the agricultural use. Hence, there is an arising ...

Temporal variations in the δD of leaf n-alkanes from four riparian plant species

24-Apr-2016 | Author(s): Abigail M. Oakes, Michael T. Hren, Organic Geochemistry, 2016

Publication date: Available online 20 April 2016 Source:Organic Geochemistry Author(s): Abigail M. Oakes, Michael T. Hren The hydrogen isotopic composition of terrestrial plant leaf waxes is widely used as a proxy for the isotopic composition of ambient water at the time of plant ...

Properties of Cookies Made with Natural Wax–Vegetable Oil Organogels

30-Mar-2016 | Hong‐Sik Hwang, Mukti Singh, Suyong Lee, Journal of Food Science, 2016

Abstract The aim of this study was to examine the feasibility of cookies in which the conventional margarine is replaced with an organogel of vegetable oil (VO) and natural wax. New cookies from VO organogels contain no trans fats and much less saturated fats than cookies made with a ...
