ELECTRICAL CONDUCTIVITY AND OSMOTIC CONDITIONING WITH POLYETHYLENE GLYCOL IN STORAGE Caryocar brasiliense SEEDS

open access: yesRevista de Agricultura Neotropical, 2023
The propagation of Caryocar brasiliense (pequizeiro) is still little known. This study aimed to evaluate different osmotic conditions with polyethylene glycol (PEG) in the imbibition process and in the germination of pequi seeds, in addition to ...

Enhanced seed germination of Ilex dumosa R. (Aquifoliaceae) through in vitro culture of cut pyrenes [PDF]

open access: yes, 2011
An in vitro culture protocol was developed that increased the germination percentage and decreased the lag time to germination for Ilex dumosa R. pyrenes as a tool for replacing the laborious task of embryo rescue technique.

Prospects for obtaining oil from the kernels of the seeds of different varieties of peaches

open access: yesНауковий вісник Львівського національного університету ветеринарної медицини та біотехнологій імені С.З. Ґжицького. Серія: Харчові технології, 2023
Peach stones are obtained as waste at fruit canneries and fruit-drying enterprises. It is specific of this raw material that fruit stones normally enter oil-producing plants in batches which are unsorted mixtures of pyrenes from different fruit cultivars.

Bacillus subtilis is a Potential Degrader of Pyrene and Benzo[a]pyrene [PDF]

open access: yesInternational Journal of Environmental Research and Public Health, 2005
Polycyclic Aromatic Hydrocarbons (PAHs) are a group of compounds that pose many health threats to human and animal life. They occur in nature as a result of incomplete combustion of organic matter, as well as from many anthropogenic sources including cigarette smoke and automobile exhaust.

Non-K Region Disubstituted Pyrenes (1,3-, 1,6- and 1,8-) by (Hetero)Aryl Groups—Review

open access: yesMolecules, 2019
Disubstituted pyrenes at the non-K region by the same or different (hetero)aryl groups have proven to be an increasingly interesting area of research for scientists over the last decade due to their optical and photophysical properties.

Pyrene-4,5,9,10-Tetrachalcogenone Derivatives: A Computational Study on Their Potential Use as Materials for Batteries

open access: yesChemistry Proceedings, 2022
Polycyclic aromatic hydrocarbons are versatile building blocks for conjugated materials and can be applied in molecular electronics. Pyrenes are known as the best organic chromophores, and pyrene itself is known as an electron donor.

A pyrene maleimide with a flexible linker for sampling of longer inter-thiol distances by excimer formation. [PDF]

open access: yesPLoS ONE, 2011
Pyrene-containing compounds are commonly used in a number of fluorescence-based applications because they can form excited-state dimers (excimers) by stacking interaction between excited-state and ground-state monomers.

Dynamic exciton localisation in a pyrene–BODIPY–pyrene dye conjugate [PDF]

open access: yesPhysical Chemistry Chemical Physics, 2019
The photophysics of a molecular triad consisting of a BODIPY dye and two pyrene chromophores attached in 2-position are investigated by steady state and fs-time resolved transient absorption spectroscopy as well as by field induced surface hopping (FISH) simulations.
