Modeling of secondary organic aerosol yields from laboratory chamber data [PDF]

, 2009
Laboratory chamber data serve as the basis for constraining models of secondary organic aerosol (SOA) formation. Current models fall into three categories: empirical two-product (Odum), product-specific, and volatility basis set. The product-specific and

Chitosan‐Based pH‐Responsive Films and Edible Coatings to Enhance Fruit Shelf‐Life: Impact of Plant Biomolecules and Composition

Food Chemistry International, EarlyView.
Chitosan based coatings/films forming solution with the use ofplant extracts and parameters for fruit shelf life analysis. ABSTRACT Fresh fruits are a natural source of various minerals and vitamins, which are essential for human health. However, a rapid rate of respiration, water loss and fast ripening ability result in shorter shelf life and ...

Attenuating effect of α‐pinene on neurobehavioural deficit, oxidative damage and inflammatory response following focal ischaemic stroke in rat

The Journal of pharmacy and pharmacology, 2019
Oxidative stress and inflammation have a critical role in the pathogenesis of ischaemic stroke. Alpha‐pinene is a monoterpenoid molecule with anti‐inflammatory and antioxidant properties.

Effect of Fruit Maturation Stage on the Chemical Composition and Antioxidant and Cytotoxic Activities of Piper nigrum Essential Oil

Flavour and Fragrance Journal, EarlyView.
The essential oils of Piper nigrum show marked chemical and biological variation across fruit maturation stages. Ripe fruits yield oils with the strongest antioxidant and cytotoxic activities, demonstrating that maturation directly modulates volatile composition and enhances the bioactive potential of this aromatic species.

Composition and Enantiomeric Analysis of the Essential Oil of the Fruits and the Leaves of Pistacia vera from Greece

Molecules, 2007
The essential oils of the fruits and the leaves of pistachio (Pistacia vera L.) were analyzed by GC and GC/MS. Fresh unripe pistachio fruits were richer in essential oil (0.5 %, w/w) than the leaves (0.1 %, w/w).

Emissions of biogenic volatile organic compounds and subsequent formation of secondary organic aerosols in a Larix kaempferi forest [PDF]

Atmospheric Chemistry and Physics, 2015
We conducted simultaneous measurements of concentrations and above-canopy fluxes of isoprene and α-pinene, along with their oxidation products in aerosols in a Larix kaempferi (Japanese larch) forest in summer 2012.

Influence of Humidity, Temperature and Radicals on the Formation and Thermal Properties of Secondary Organic Aerosol (SOA) from Ozonolysis of {\beta}-pinene

, 2013
The influence of water and radicals on SOAs produced by {\beta}-pinene ozonolysis was investigated at 298 and 288 K using a laminar flow reactor. A volatility tandem differential mobility analyzer (VTDMA) was used to measure the evaporation of the SOA ...
