High-Harmonic Generation from Spin-Polarised Defects in Solids
(Nature, 2020-01-31)
The generation of high-order harmonics in gases enabled to probe the attosecond electron dynamics in atoms and molecules with unprecedented resolution. Extending these techniques to solids, which were originally developed ...
Collective near-field coupling and nonlocal phenomena in infrared-phononic metasurfaces for nano-light canalization
(Nature, 2020-07-21)
Polaritons - coupled excitations of photons and dipolar matter excitations - can propagate along anisotropic metasurfaces with either hyperbolic or elliptical dispersion. At the transition from hyperbolic to elliptical ...
Tunable Polymeric Scaffolds for Enzyme Immobilization
(Frontiers Media, 2020-07-30)
The number of methodologies for the immobilization of enzymes using polymeric supports is continuously growing due to the developments in the fields of biotechnology, polymer chemistry, and nanotechnology in the last years. ...
Impact of MOF-5 on pyrrolidinium-based poly(ionic liquid)/ionic liquid membranes for biogas upgrading
(ACS, 2019-12-03)
Bearing in mind that Metal Organic Frameworks (MOFs) have remarkable CO2 adsorption selectivity and Mixed Matrix Membranes (MMMs) have been identified as potential solution for advancing the current state of the art of ...
Methodology and Research Protocols People with Disabilities and Other Forms of Vulnerability to the COVID-19 Pandemic: Study Protocol for a Scoping Review and Thematic Analysis
(Elsevier, 2020-12)
Objectives: To develop a protocol for a scoping review mapping as well as thematically analyzing the literature on the effect of, and responses to, the coronavirus disease 2019 (COVID-19) pandemic, focused on people with ...
Topologization of Beta-Antimonene on Bi2Se3 Via Proximity Effects
(Nature, 2020-09-03)
Topological surface states usually emerge at the boundary between a topological and a conventional insulator. Their precise physical character and spatial localization depend on the complex interplay between the chemical, ...
Electronic Decoupling of Polyacenes from the Underlying Metal Substrate bysp(3)Carbon Atoms
(Nature, 2020-09-15)
Many organic molecules exhibit interesting electronic and magnetic properties, but as they are deposited onto a metallic substrate, their hybridisation often impacts on the observed characteristics. Here, the authors report ...
Giant Exciton Mott Density in Anatase TiO2
(American Physical Society, 2020-09-10)
Elucidating the carrier density at which strongly bound excitons dissociate into a plasma of uncorrelated electron-hole pairs is a central topic in the many-body physics of semiconductors. However, there is a lack of ...
Hetero-Diels-Alder Cycloaddition with RAFT Polymers as Bioconjugation Platform
(Wiley, 2020-11-02)
We introduce the bioconjugation of polymers synthesized by RAFT polymerization, bearing no specific functional end group, by means of hetero-Diels-Alder cycloaddition through their inherent terminal thiocarbonylthio moiety ...
Antibacterial and cytotoxic activities of new sphingolipids and other constituents isolated from Cissus incisa leaves
(Elsevier, 2020-08)
Cissus incisa is used in traditional Mexican medicine to treat certain ailments, infectious or cancerous diseases. Excepting for our previous research, this species had no scientific reports validating its traditional use. ...
