In this study, we report the potential of 2D/2D TiO2-GO-ZnFe2O4 photocatalyst obtained using the fluorine-free lyophilization technique for the degradation of ibuprofen belonging to the group of active pharmaceutical ... -
Systematic diffusion-ordered spectroscopy for the selective determination of molecular weight in real lignins and fractions arising from base-catalyzed depolymerization reaction mixtures
The valorization of biorefinery downstream lignin fractions is a key issue in increasing the sustainability of second-generation biofuels. The development of reliable methodologies for the selective determination of the ... -
Tailoring magnetic and transport anisotropies in Co100−x –Cux thin films through obliquely grown nano-sheets
The magnetic and transport properties of pulsed laser-deposited Co100−x –Cux thin films were tailored through their nano-morphology and composition by controlling for the deposition geometry, namely normal or oblique ... -
Tailoring the structural and magnetic properties of Co-Zn nanosized ferrites for hyperthermia applications
A comparative study of the magnetic properties (magnetic moment, magnetocrystalline anisotropy) and hyperthermia response in Co-Zn spinel nanoparticles is presented. The CoxZn1-xFe2O4 nanoparticles (x = 1, 0.5, 0.4, 0.3, ... -
A techno-economic and life cycle assessment for the production of green methanol from CO2: catalyst and process bottlenecks
The success of catalytic schemes for the large-scale valorization of CO2 does not only depend on the development of active, selective and stable catalytic materials but also on the overall process design. Here we present ... -
Testing of black-carrots-derived fluorescence imaging and anti-metastatic potential
(Elsevier, 2024) Artículo / ArtikuluaThis paper explains the basis for the excitation energy-independent fluorescence emission of biomass-derived carbon dots (CDs) and shows that these CDs have excellent anti-melanoma and anti-metastatic potential. Additionally, ... -
Thermally induced structural transitions between single-crystalline states in the first hybrid compound combining Keggin-type clusters with metal-cyclam complexes: from two-dimensional covalent assemblies to discrete molecular species
A hydrothermal reaction between the monolacunary polyoxometalate [SiW11O39]8-, a copper(II) salt, and 1,4,8,11-tetraazacyclotetradecane (cyclam) affords the first example of a hybrid compound combining metal complexes of ... -
Thermodynamic and physical property estimation of compounds derived from the fast pyrolysis of lignocellulosic materials
The development of biomass pyrolysis oil refineries is a very promising path for the production of biofuels and bioproducts from lignocellulosic materials. Given that bio-oil is a complex mixture of organic compounds, the ... -
Three classes of hemoglobins are required for optimal vegetative and reproductive growth of Lotus japonicus: genetic and biochemical characterization of LjGlb2-1
Legumes express two major types of hemoglobins, namely symbiotic (leghemoglobins) and non-symbiotic (phytoglobins), with the latter being categorized into three classes according to phylogeny and biochemistry. Using knockout ... -
Thrust actuator with passive restoration force for wide gap magnetic bearings
Active thrust magnetic bearings provide an axial force to balance the moving parts of machines. However, most devices produce null or unbalancing passive forces. Furthermore, reported designs usually feature very small ... -
Titania-triethanolamine-kaolinite nanocomposites as adsorbents and photocatalysts of herbicides
Kaolinite-titania adsorbents/photocatalysts were prepared by functionalizing a kaolinite with titanium(IV) triethanolaminate isopropoxide by the sol–gel route. These materials were characterized by various techniques and ... -
Toward optimal irrigation management at the plot level: evaluation of commercial water potential sensors
