The development of microreactors that operate under harsh conditions is always of great interest for many applications. Here we present a microfabrication process based on low-temperature co-fired ceramic (LTCC) technology for producing microreactors which are able to perform chemical processes at elevated temperature (>400 °C) and against concentrated harsh chemicals such as sodium hydroxide, ...

Using GC-MS and GC-flame ionization detection (FID)/olfactometry, 95 volatile components were detected in orange essence oil, of which 55 were aroma active. In terms of FID peak area the most abundant compounds were: limonene, 94.5%; myrcene, 1%; valencene, 0.8%; linalool, 0.7%, and octanal, decanal, and ethyl butyrate, 0.3% each. One hundred percent of the aroma activity was generated by sligh...

Photoactivation of the visual rhodopsin, a prototypical G protein-coupled receptor (GPCR), involves efficient conversion of the intrinsic inverse-agonist 11-cis-retinal to the all-trans agonist. This event leads to the rearrangement of the heptahelical transmembrane bundle, which is thought to be shared by hundreds of GPCRs. To examine this activation mechanism, we determined the x-ray crystall...

The study aims to analyze the chemical composition of Suaeda aegyptiaca essential oil (PSAE) by GC–MS, produce nanoemulsified (NSAE) using ultrasound, and compare antimicrobial antioxidant activity PSAE NSAE in laboratory medium rainbow trout fish (Oncorhynchus mykiss). Geranyl-acetone (30.52%) p-Vinylguaiacol (10.66%), (e)-β-ionone (7.79%) were main compounds. mean droplet size diameter, polyd...

This work aimed to investigate the occurrence of different monoterpenoids and norisoprenoids in 10 monovarietal Italian red wines (Aglianico, Cannonau, Corvina, Montepulciano, Nebbiolo, Nerello, Primitivo, Raboso, Sangiovese Teroldego) from 12 regions across Italy. The were produced their terroirs following oenological practices legislation respective appellation. Data showed that wine varietal...

Abstract – Retinal is a chromophore of foremost relevance for potential applications in bio-photonics devices. Here, we study the degenerate two-photon absorption spectrum of all-trans retinal in ethanol. We observed two peaks; one associated to the twophoton dipolar contribution to a higher energy state, which contributes to the monotonic increase of the nonlinearity below 600 nm. The other on...
