Two-step learning involved in acquiring olfactory preferences for plant volatiles by parasitic wasps

, 2012
Aphidius ervi is a parasitic wasp of several aphid species, including Acyrthosiphon pisum. This wasp is used as a biological control agent of its host aphid species in many regions of the world. Compared with responses to volatiles from intact plants, A.

The effects of diesel exhaust pollution on floral volatiles and the consequences for honey bee olfaction [PDF]

, 2015
There is growing evidence of a substantial decline in pollinators within Europe and North America, most likely caused by multiple factors such as diseases, poor nutrition, habitat loss, insecticides, and environmental pollution. Diesel exhaust could be a

Electrode and Microstructure Dependence of Oxygen Diffusion in Ferroelectric Hafnium Zirconium Oxide Thin Films

Advanced Functional Materials, EarlyView.
Significant nanoscale oxygen diffusion coefficient variations are measured in ferroelectric hafnium zirconium oxide films with grain boundaries and electrode interfaces exhibiting values 104 times larger than the grain cores. Overall coefficients are 10X larger for films prepared with metal nitride electrodes compared to refractory metals. New insights

Historical Foundation and Practical Guideline for Ferroelectric Switching Kinetic Studies

Advanced Functional Materials, EarlyView.
The P and U pulses in the conventional PUND measurements are not identical because of the interplay between switching current and the measurement circuit components. This circuit effect can lead to a shift in polarization transients and misinterpreted physics in the switching kinetics.

A review of the volatiles from the healthy human body

, 2014
A compendium of all the volatile organic compounds (VOCs) emanating from the human body (the volatolome) is for the first time reported. 1840 VOCs have been assigned from breath (872), saliva (359), blood (154), milk (256), skin secretions (532) urine ...

Support‐Controlled Reaction Pathways via Dynamic Sulfur‐Mediated Interfaces for Selective Urea Electrolysis

Advanced Functional Materials, EarlyView.
Sulfur‐doped graphitized carbon nanofibers act as adaptive catalyst–support platforms, enabling dynamic sulfur‐mediated reconstruction and strong metal–support interactions. This unique behavior enhances catalyst stability and controls reaction pathways, achieving highly selective urea oxidation (∼92% N2) coupled with efficient hydrogen evolution ...

Plant volatiles and components influencing behavior of the field slug, deroceras-reticulatum (mull)

, 1980
A new bioassay was devised in which slugs were allowed to follow trails of the aqueous volatiles isolated from plants by vacuum distillation. Volatiles from lettuce, carrot and dandelion induced greatest response.
