UV tunable biobased pressure sensitive adhesives containing piperonyl methacrylate
(ACS, 2019)Novel waterborne pressure sensitive adhesives (PSA) with biobased contents up to 71%, and UV-light tunable features have been developed using piperonyl methacrylate as hard monomer. The biobased monomer was synthesized ... -
UV- and visible-light photocatalysis using Ni–Co bimetallic and monometallic hydrotalcite-like materials for enhanced CO2 methanation in sabatier reaction
(Elsevier, 2023-08)The CO2 catalytic reduction activities of four different Co-modified Ni-based catalysts derived from hydrotalcite-like materials (HTCs) prepared by co-precipitation method were investigated under thermal and photocatalytic ... -
UV-cross-linked poly(ethylene oxide carbonate) as free standing solid polymer electrolyte for lithium batteries
(Elsevier, 2019-04-10)Aliphatic polycarbonates have emerged as promising polymer electrolytes due to their combination of moderate ionic conductivity and high lithium transference numbers. However, the mechanical properties of the aliphatic ... -
UV-curable acrylic end-capped amphoteric waterborne polyurethane coatings
(Elsevier, 2024-03)Waterborne polyurethane dispersions (WPUs) are environmentally friendly coatings since they present low amount of volatile organic compound amounts (VOCs). In the majority of the WPUs the dispersions are balanced with ... -
UV-Selective Optically Transparent Zn(O,S)-Based Solar Cells
(Wiley, 2020-11)This work reports experimental evidence of a photovoltaic effect in transparent UV-selective Zn(O,S)-based heterojunctions. Zn(O,S) has a strong interest for the development of UV-selective solar cells with high transparency ... -

U–Pb dating of carbonate veins constraining timing of beef growth and oil generation within Vaca Muerta Formation and compression history in the Neuquén Basin along the Andean fold and thrust belt
(Elsevier, 2021-10)[EN]We combine structural analysis of fractures with 22 U–Pb dates measured in fracture-filling carbonate cements from bed-parallel fibrous calcite veins (beef), conjugated veins and faults within the Vaca Muerta Formation ... -
Vacancies mediated ordering in Ni-Mn-Ga shape memory alloys
(Elsevier, 2022-07-01)[EN] Vacancy mediated diffusion is the main atomic mechanism that controls the ordering of substitutional alloys. In particular, in Ni-Mn-Ga shape memory alloys vacancies control the evolution of the L21 atomic order degree ... -

Vacuum state of the Dirac field in de Sitter space and entanglement entropy
(Springer, 2017-03-13)We compute the entanglement entropy of a free massive Dirac field between two causally disconnected open charts in de Sitter space. We first derive the Bunch-Davies vacuum mode functions of the Dirac field. We find there ... -
