Imaging moiré deformation and dynamics in twisted bilayer graphene
(Nature Research, 2022-01)
[EN] In 'magic angle' twisted bilayer graphene (TBG) a flat band forms, yielding correlated insulator behavior and superconductivity. In general, the moire structure in TBG varies spatially, influencing the overall conductance ...
Synthesis and applications in immunoassays of antibody-protected nanoclusters
(2022-03-18)
Los nanoclusters (NCs) han ganado atención los últimos años debido a sus propiedades ópticas y químicas dependientes del tamaño. En esta tesis se presenta el primer método para la síntesis de NCs empleando anticuerpos como ...
Crystallization of a Self-Assembling Nucleator in Poly(L-lactide) Melt
(American Chemical Society, 2021-09-01)
[EN]In the present work, crystallization of a soluble nucleator N, N′, N″-tricyclohexyl-1,3,5-benzenetricarboxylamide (TMC-328) in a poly(l-lactic acid) (PLLA) matrix has been studied at different temperatures. Based on ...
Realization of nearly dispersionless bands with strong orbital anisotropy from destructive interference in twisted bilayer MoS2
(Nature Research, 2021-09)
[EN]Recently, the twist angle between adjacent sheets of stacked van der Waals materials emerged as a new knob to engineer correlated states of matter in two-dimensional heterostructures in a controlled manner, giving rise ...
Simulating Vibronic Spectra without Born-Oppenheimer Surfaces
(ACS Publications, 2021-04-01)
We show how linear vibronic spectra in molecular systems can be simulated efficiently using first-principles approaches without relying on the explicit use of multiple Born-Oppenheimer potential energy surfaces. We demonstrate ...
Nanoparticle-Doped Hybrid Polyelectrolyte Microcapsules with Controlled Photoluminescence for Potential Bioimaging Applications
(MDPI, 2021-11-24)
Fluorescent imaging is widely used in the diagnosis and tracking of the distribution, interaction, and transformation processes at molecular, cellular, and tissue levels. To be detectable, delivery systems should exhibit ...
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 ...
Large Perpendicular Magnetic Anisotropy in Nanometer-Thick Epitaxial Graphene/Co/Heavy Metal Heterostructures for Spin-Orbitronics Devices
(American Chemical Society, 2021-05-28)
Nanometer-thick epitaxial Co films intercalated between graphene (Gr) and a heavy metal (HM) substrate are promising systems for the development of spin-orbitronic devices due to their large perpendicular magnetic anisotropy ...
Can aluminum, a non-redox metal, alter the thermodynamics of key biological redox processes? The DPPH-QH2 radical scavenging reaction as a test case
(Elsevier, 2022-02-01)
[EN] The increased bioavailability of aluminum has led to a concern about its toxicity on living systems. Among the most important toxic effects, it has been proven that aluminum increases oxidative stress in biological ...
A Review on Current Strategies for the Modulation of Thermomechanical, Barrier, and Biodegradation Properties of Poly (Butylene Succinate) (PBS) and Its Random Copolymers
(MDPI, 2022-03-03)
The impact of plastics on the environment can be mitigated by employing biobased and/or biodegradable materials (i.e., bioplastics) instead of the traditional “commodities”. In this context, poly (butylene succinate) (PBS) ...
