Sectioning and Electron Microscopy of Eucalypt Leaf Waxes [PDF]

open access: yesAustralian Journal of Biological Sciences, 1964
A method is described of preparing leaf sections for electron microscopy. which preserves the surface wax structures; it involves the evaporation of gold-palladium on to the waxy leaf surface before dehydration and embedding with the usual solvents.

Understanding the Middle Miocene Climatic Optimum: Evaluation of Deuterium Values (δD) Related to Precipitation and Temperature [PDF]

open access: yes, 2013
The Middle Miocene Climate Optimum was a unique warming period in the Earth’s geologic history, when a high global mean annual temperature was accompanied by a relatively low global CO2 concentration. Hydrogen isotopic signals (specifically molecular δD,

Assessing the capacity of trees and shrubs species to accumulate of particulate matter (PM10, PM2.5 and PM0.2)

open access: yesسلامت و محیط, 2019
Background and Objective: Today, the presence and increase of particulate matter is one of the serious factors that threaten human health. In the meantime, trees can accumulate airborne particles by their foliage.
