Unraveling materials Berry curvature and Chern numbers from real-time evolution of Bloch states
(Natlacad Sciences, 2019-03-05)Materials can be classified by the topological character of their electronic structure and, in this perspective, global attributes immune to local deformations have been discussed in terms of Berry curvature and Chern ... -
Unraveling Sugar Binding Modes to DC-SIGN by Employing Fluorinated Carbohydrates
(MDPI, 2019-06-25)A fluorine nuclear magnetic resonance (F-19-NMR)-based method is employed to assess the binding preferences and interaction details of a library of synthetic fluorinated monosaccharides towards dendritic cell-specific ... -
Unraveling the Effect of Singlet Oxygen on Metal-O2 Batteries: Strategies Toward Deactivation
(Frontiers Media, 2020-07-22)Aprotic metal-O(2)batteries have attracted the interest of the research community due to their high theoretical energy density that target them as potential energy storage systems for automotive applications. At present, ... -
Unraveling the effects of Fe and Mn promoters on the tungstated zirconia catalyst: A DFT study
(Elsevier, 2022-10)Periodic DFT calculations are performed to unravel the effect of the incorporation of Fe and Mn into the tung-stated zirconia catalyst, (WO3)x/ZrO2 (x = 1,3), in their electronic, geometric, and catalytic properties. Our ... -
Unraveling the environmental and anthropogenic drivers of bacterial community changes in the Estuary of Bilbao and its tributaries
(Public Library Science, 2017-06-08)In this study, 16S rRNA gene sequencing was used to characterize the changes in taxonomic composition and environmental factors significantly influencing bacterial community structure across an annual cycle in the Estuary ... -
Unraveling the In Vitro Antitumor Activity of Vismia Baccifera Against HepG2: Role of Hydrogen Peroxide
(Elsevier, 2018-06-27)Currently natural products derived from plants are receiving huge attention because of their antitumor activities. In previous work we reported that an aqueous leaf extract of Vismia baccifera induced toxicity in HepG2. ... -
Unraveling the Photoprotective Response of Lichenized and Free-Living Green Algae (Trebouxiophyceae, Chlorophyta) to Photochilling Stress
(Frontiers Media, 2017-07-04)Lichens and free-living terrestrial algae are widespread across many habitats and develop successfully in ecosystems where a cold winter limits survival. With the goal of comparing photoprotective responses in free-living ... -
Unraveling the role of the thermal and laser impacts on the blackening of cinnabar in the mural paintings of Pompeii
(Springer, 2022-10-27)The blackening of red cinnabar (α-HgS) pigment has traditionally been explained by its conversion into black metacinnabar (β-HgS). Scarce is however the scientific evidence that supports this hypothesis in polychrome ... -
Unravelling metabolic mechanisms behind chloroplast desiccation tolerance: chlorophyllous fern spore as a new promising unicellular model
(Elsevier, 2018-11-22)Fern spores are unicellular structures produced by the sporophyte generation that give rise to the haploid gametophyte. When released from the sporangium, spores are desiccation tolerant (DT) in the royal fern (Osmunda ... -
Unravelling the electrochemical activation and the reaction mechanism of maricite-NaFePO4 using multimodal operando techniques
(RSC, 2023-08-23)The electrochemical properties of maricite NaFePO4 can be activated by ball milling with carbon. The origin of such activation is still unclear, as this material does not exhibit apparent open channels for Na+diffusion. ... -
Unravelling the Intertwined Atomic and Bulk Nature of Localised Excitons by Attosecond Spectroscopy
(Springer, 2021-02-15)The electro-optical properties of most semiconductors and insulators of technological interest are dominated by the presence of electron-hole quasi-particles, called excitons. The manipulation of excitons in dielectrics ... -
