Luminescent materials doped with rare-earth (RE) ions have emerged as powerful tools in thermometry, offering high sensitivity and accuracy.
Essential oils (EOs) obtained from Juniperus communis L. are frequently used in the production of bioproducts. However, there no studies regarding industrial crops' production, allowing for better control quality and juniper EOs. To select plant material developing future crops this species northern Spain, four locations where shrub grows wild were selected samples both genera collected. The EOs by steam distillation, their chemical composition bioactivity evaluated. results showed that...
Increasing applications and markets for essential oils could bring new opportunities cost-effective sustainable management of unused forestry biomass; however, better knowledge the production application such is necessary. The objective this work to contribute greater oil on a pilot scale from foliage biomass wild shrubs tree residues produced in some enhancement operations study their antioxidant capacity (ORAC—oxygen radical absorbance capacity). Fresh (twigs) seven species (E. globulus,...
Cupressus sempervirens L., Juniperus communis L. and Cistus ladanifer are Mediterranean arboreal shrub species that possess essential oils (EO) in their leaves branches. This study aimed at characterizing the EOs obtained by steam distillation from three collected different locations Spain (Almazán, Andévalo, Barriomartín, Cerezal, Ermitas Huéscar). For this purpose, volatiles composition was determined GC-MS, bioactivities were evaluated. The highest content terpenes observed C. (Huéscar...
The interest for essential oils is increasing, alongside ongoing scientific research into distillation techniques. This process generates significant solid residue that could be revalorized as energy source. study explores the recovery of fraction produced during three aromatic plants: Cistus ladanifer, Juniperus communis and Rosmarinus officinalis. Two conventional technologies were considered compared through an balance: biofuel production biogas generation. In case biofuels, fractionation...
Cistus ladanifer is a Mediterranean native plant from which valuable products, such as essential oil, are obtained. Manual harvesting of the plants in wild shrublands usual during short periods time. Their mechanised could increase volume harvested and prevent fires, further storage collected being necessary. The objective this work to study influence period mechanically bales on oil yield qualitative composition. trials were carried out with an adapted commercial harvester baler was...
For guayule (Parthenium argentatum A. Gray) to become a viable market option, it will be necessary exploit not only the rubber and resin components, but also other high-value plant products such as essential oils (EOs). A detailed EO profiling study was conducted on 16 accessions for first time, which revealed significant differences in yield profile among them. Accession AZ-2 had highest up 0.9% (dry weight), followed by CFS18–2005, CAL-7, CFS17–2005. These yields were comparable with those...
The fluctuation in yield, composition, antibacterial and antioxidant activity of the essential oil (EO) rockrose (Cistus ladanifer L.) obtained from two locations central Spain was analysed compared over course one year. Fifteen kilograms C. ladanifer, collected monthly or fortnightly sites with different plant age (7 12 years), underwent steam-distillation. GC (FID)-MS analyses were done to determine volatile profile EOs. Obtained EO yields varied significantly (P < 0.001) throughout year,...
Permittivity of materials is utmost importance for microwave applicators’ design and to predict high-frequency dielectric heating materials. In the case aromatic plant biomass, however, there are few data that help researchers applicators microwave-assisted extraction. this work, permittivity cypress rockrose biomass samples were measured versus temperature, density, moisture content. A resonant technique based on a coaxial bi-reentrant cavity was employed obtain complex as function those...
Biomass storage is an essential requirement in the supply chain of bio-refineries and power plants. This research aims to evaluate influence long-term outdoor (1 year) baled rockrose (Cistus laurifolius L.) shrub biomass on biofuel’s quality, pre-treatment processes combustion emissions industrial boiler. The raw material was obtained from different shrublands north central Spain. A total 233 tWM (tones wet matter) were used produce biofuels (30 mm milled Ø 8 pellets) pilot plants at...
GaP as one of the III–V semiconductors has an indirect band gap in its natural zinc-blend (ZB) crystal phase, limiting applications optoelectronics. The atomic arrangements ZB GaP, however, can be changed by adding energy to system, for example, using strain and defects. In such a way, crystallized wurtzite (WZ) phase with direct yellow–green range promising new optical properties. nanostructures offer great possibility induce strain, hence, expect obtain WZ modifying geometry dimensionality...
Juniperus communis L. is a species commonly grown in regions of the Northern Hemisphere, and good candidate to be cultivated marginal lands. Plants coming from pruning performed natural population located Spain were used assess yield quality different products obtained following cascade principle. A total 1050 kg foliage biomass crushed, steam-distilled, separated into fractions produce biochar absorbents for pet industry using pilot plants. The analysed. essential oil, with 0.45% dry basis...
