Supernucleation Dominates Lignin/Poly(ethylene oxide) Crystallization Kinetics
(American Chemical Society, 2022)
The effect of lignin nanoparticles (LNPs) on the crystallization kinetics of poly(ethylene oxide) (PEO) is examined. Lignin from spruce and ionic isolation was used to prepare LNPs with a number-averaged diameter of 85 nm ...
Disentangling the Calorimetric Glass-Transition Trace in Polymer/ Oligomer Mixtures from the Modeling of Dielectric Relaxation and the Input of Small-Angle Neutron Scattering
(American Chemical Society, 2022-08)
We have disentangled the contributions to the glass transition as observed by differential scanning calorimetry (DSC) on simplified systems of industrial interest consisting of blends of styrene-butadiene rubber (SBR) and ...
Effect of Chain Stereoconfiguration on Poly(3-hydroxybutyrate) Crystallization Kinetics
(American Chemical Society, 2022-08)
Poly(3-hydroxybutyrate) (PHB) is naturally accumulated by bacteria but can also be synthesized chemically. Its processability is limited, as it tends to degrade at temperatures above its melting temperature; hence, ...
Multiple headspace solid-phase microextraction (MHS-SPME) methodology applied to the determination of volatile metabolites of plasticizers in human urine
(Elsevier, 2022-09)
In the present work, an optimization and validation of an analytical method for the determination of two plasticizer metabolites, 2-ethylhexanol and 4-heptanone in urine, were carried out by multiple headspace solid-phase ...
Multicentre study of magnet ingestion in Spanish paediatric emergency departments.
(Elsevier, 2022-11)
INTRODUCTION: The ingestion of magnetic objects can cause complications in children, and there are no epidemiological or clinical data on the subject in Spain.
OBJECTIVES: To determine the incidence, epidemiological ...
What Accounts for Physical Activity during Pregnancy? A Study on the Sociodemographic Predictors of Self-Reported and Objectively Assessed Physical Activity during the 1st and 2nd Trimesters of Pregnancy
(MDPI, 2020-04-07)
Physical activity (PA) during pregnancy has positive health implications for both mother and child. However, current literature indicates that not all pregnant women meet the international recommendations for PA (at least ...
Iodine Deficiency and Mortality in Spanish Adults: Di@bet.es Study
(Mary Ann Liebert, 2021-01-01)
Background:Longitudinal data assessing the impact of iodine deficiency (ID) on mortality are scarce. We aimed to study the association between the state of iodine nutrition and the risk of total and cause-specific mortality ...
Association between long term exposure to particulate matter and incident hypertension in Spain
(Nature Research, 2021-10-05)
[EN]Exposure to air particulate matter has been linked with hypertension and blood pressure levels. The metabolic risks of air pollution could vary according to the specific characteristics of each area, and has not been ...
Influence of lignin modifications on physically crosslinked lignin hydrogels for drug delivery applications
(Elsevier, 2022-09)
So far, the possibility of synthesizing hydrogels based on multiple biopolymers has been investigated, and among them lignin has proven to be one of the potentials for this purpose due to the multiple advantages it offers. ...
Deep transfer learning-based gaze tracking for behavioral activity recognition
(Elsevier, 2022-08)
Computational Ethology studies focused on human beings is usually referred as Human Activity Recognition (HAR). Specifically, this paper belongs to a line of work on the identification of broad cognitive activities that ...
