Chemical Ecology of Clytini (Coleoptera: Cerambycidae)
… that three methylalkanes present in the wax layer of females are sufficient to elicit a mating response from males.

Factors contributing to variation in cuticular hydrocarbon profiles of two species of longhorned beetles (Coleoptera: Cerambycidae)
… (F.) and Xylotrechus colonus F. The cuticular wax layer of N. acuminatus comprises at least 20 hydrocarbons ranging from C24 to C29, three of which serve as the contact pheromone of females. The wax layer of X. colonus contains at least 17 hydrocarbons that range from C25 to C31, and the …

The structure and function of Gene's organ and its associated glands in ticks
… describe the structure of Gene's organ, the egg-waxing organ in ticks, using electron microscopy. Both ultrastructural and physiological aspects are investigated in two important pest species, Boophilus microplus and Amblyomma variegatum. The organ performs an essential function in females by …

Opuntia ficus-indica: a climate-resilient biomass feedstock for low-input drylands agriculture
… putative polymeric aldehydes in the epicuticular wax layer and recalcitrant epoxy-ω-hydroxy fatty acids in cutin that might help to reduce water losses through the cuticle. A metabolic study using well-watered and water-deficit stressed mesophyll and epidermis tissues identified numerous responses …

Investigating The Relationship Between Surface Topology And Functional Characteristics For Injection Moulded Thermoplastic Components
… the surface of a gecko skin, and the hydrophobic wax layer of forest leaves. Main barriers to adoption include that these surfaces alone are difficult to manufacture on 3D products, expensive to fabricate on a large scale and do not last long when subjected to environmental wear. Replication of …

The effects of adjuvents upon the pesticide uptake and penetration of foliage
… the compound does not partition into the surface waxes and crystallises as an external deposit. This deposit is stable to volatilization and photochemical and biochemical degradation, and is depleted by foliar penetration. Adsorbtion by the leaf surface wax is initially rapid and thereafter occurs …

Introduction of a thermo-sensitive non-polar species into polyelectrolyte multilayer capsules for drug delivery
The layer-by-layer assembly (LBL) of polyelectrolytes has been extensively studied for the preparation of ultrathin films due to the versatility of the build-up process. The control of the permeability of these layers is particularly important as there are potential drug delivery applications. …

NMR Studies of Emulsions in Porous Media and Applications to Fischer-Tropsch Synthesis
… development. Finally, the phase behaviour of wax and water was studied post-FTS $\textit{in situ}$ in 1~wt$\%$~Ru/TiO2 catalysts at both 180 and 220~$\degree$ C. Emulsion formation was detected by slowly increasing the water partial pressure between 0.3~-~0.95. At …

IDENTIFICATION OF ULTRASTRUCTURAL AND BIOCHEMICAL MARKERS OF FROST AVOIDANCE IN THE CUTICULAR LAYER OF CORN
… and biochemical changes in the cuticular wax layer in all four genotypes. These changes were measured using a suite of complementary techniques including: thermal imaging, hydrophobicity, Confocal Laser Scanning Microscopy (CLSM), Attenuated Total internal Reflectance (ATR-FTIR), and Gas …
