Ripening-related cell wall modifications in olive (Olea europaea L.) fruit: A survey of nine genotypes
(Elsevier, 2020-08-04)The production of olive (Olea europaea L.) is very important economically in many areas of the world, and particularly in countries around the Mediterranean basin. Ripening-associated modifications in cell wall composition ... -
Role of charge regulation and fluctuations in the conformational and mechanical properties of weak flexible polyelectrolytes
(MDPI, 2019-11-29)This work addresses the role of charge regulation (CR) and the associated fluctuations in the conformational and mechanical properties of weak polyelectrolytes. Due to CR, changes in the pH-value modifies the average ... -
Seasonal variations in proton binding characteristics of dissolved organic matter isolated from the southwest baltic sea
(ACS publications, 2021)The physicochemical characteristics of dissolved organic matter (DOM) strongly influence its interactions with inorganic species such as protons and trace elements in natural waters. We collected water samples at Boknis ... -
Selection footprints in barley breeding lines detected by combining genotyping-by-sequencing with reference genome information
(Springer, 2015)This study is a retrospective analysis of an elite cross from the Spanish National Barley Breeding Program. This was the most successful cross produced in the breeding program in the past 20 years. The progeny from this ... -
Shelf Life Potential and the Fruit Cuticle: The Unexpected Player
(Frontiers Media, 2019-06-12)The plant cuticle is an extracellular barrier that protects the aerial, non-lignified parts of plants from the surrounding environment, and furthermore plays important functions in organ growth and development. The role ... -
Silver nanoparticles coated with natural polysaccharides as models to study AgNP aggregation kinetics using UV-Visible spectrophotometry upon discharge in complex environments
(Elsevier, 2016-01-01)This study provides quantitative information on the aggregation and dissolution behaviour of silver nanoparticles (AgNPs) upon discharge in fresh and sea waters, represented here as NaCl solutions of increasing ionic ... -
Small-scale production of straight vegetable oil from rapeseed and its use as biofuel in the Spanish territory
(Elsevier, 2010-01)Biofuels nowadays are an important topic of study. The most significant point is the availability of bioethanol or biodiesel and their production from different raw materials. It is already known that large-scale production ... -
Solid−Liquid Equilibria in Aqueous Solutions of Tris, Tris-NaCl, Tris- TrisHCl, and Tris-(TrisH)2SO4 at Temperatures from 5 to 45 °C
(American Chemical Society, 2021-01-14)The substance Tris (or THAM, 2-amino-2-hydroxymethyl-1,3-propanediol) is used in the preparation of pH buffer solutions for applications in natural water chemistry, including seawater. The development of a chemical speciation ... -
Solvent-free biocatalytic interesterification of acrylate derivatives
(Elsevier, 2012)The ability of diverse commercial lipases and whole cells (fungal resting cells) to synthesise allyl and dichloropropyl acrylate from allyl dodecanoate through an interesterification process is presented. The process was ... -
Spanish barley landraces outperform modern cultivars at low-productivity sites
(Wiley, 2014)Barley landraces from the western Mediterranean area have not been thoroughly exploited by modern breeding. This study aims at assessing the agronomic value of a core collection of lines derived from landraces of Spanish ... -
Speciation of Inorganic Compounds in Aquatic Systems Using Diffusive Gradients in Thin-Films: A Review
(Frontiers Media, 2021)The speciation of trace metals in an aquatic system involves the determination of free ions, complexes (labile and non-labile), colloids, and the total dissolved concentration. In this paper, we review the integrated ... -
Speciation of Zn, Fe, Ca and Mg in wine with the Donnan Membrane Technique
(Elsevier, 2018)Free concentrations of Zn2+, Fe3+, Ca2+ and Mg2+ in a red wine (Raimat, Catalonia, Spain) have been determined, with the Donnan Membrane Technique (DMT) for the first time. The required equilibration time benefits from the ... -
Standardisation of near infrared hyperspectral imaging for quantification and classification of DON contaminated wheat samples
(Elsevier, 2019-12-23)Near infrared hyperspectral imaging (HSI-NIR) is considered a promising technique able to replace time-con- suming, costly and destructive classic methods to predict and classify deoxynivalenol (DON) contaminated wheat ... -
Standardization of near infrared hyperspectral imaging for wheat single kernel sorting according to deoxynivalenol level
(Elsevier, 2020-11-28)The spatial recognition feature of near infrared hyperspectral imaging (HSI-NIR) makes it potentially suitable for Fusarium and deoxynivalenol (DON) management in single kernels to break with heterogeneity of contamination ... -
Steady-state currents at inlaid and recessed microdisc electrodes for first-order EC′reactions
(Elsevier, 1999)The analytical solutions, approximate expressions and a Finite Element simulation of the steady-state currents arising from the diffusion of a regenerating electroactive species towards a disc electrode, either inlaid in ... -
Suitability of analytical methods to measure solubility for the purpose of nanoregulation
(Taylor & Francis, 2016)Solubility is an important physicochemical parameter in nanoregulation. If nanomaterial is completely soluble, then from a risk assessment point of view, its disposal can be treated much in the same way as “ordinary” ... -
Sustainable Synthesis of Omega-3 Fatty Acid Ethyl Esters from Monkfish Liver Oil
(MDPI, 2021-01-13)The search for economic and sustainable sources of polyunsaturated fatty acids (PUFAs) within the framework of the circular economy is encouraged by their proven beneficial effects on health. The extraction of monkfish ... -
