Continuous Cooling Curve Diagrams of Isotactic-Polypropylene/Polyethylene Blends: Mutual Nucleating Effects under Fast Cooling Conditions
(American Chemical Society, 2021-05-25)
Crystallization kinetics under processing-relevant cooling conditions of polyethylene/isotactic-polypropylene (PE/PP) blends, with compositions similar to real recycled blends, was investigated through an in situ temperature ...
Survival of Floquet-Bloch States in the Presence of Scattering
(American Chemical Society, 2021-06-23)
Floquet theory has spawned many exciting possibilities for electronic structure control with light, with enormous potential for future applications. The experimental demonstration in solids, however, remains largely ...
Coexistence of Superconductivity and Spin-Splitting Fields in Superconductor/Ferromagnetic Insulator Bilayers of Arbitrary Thickness
(American Physical Society, 2021-05-19)
Ferromagnetic insulators (FI) can induce a strong exchange field in an adjacent superconductor (S) via the magnetic proximity effect. This manifests as spin splitting of the BCS density of states of the superconductor, an ...
Magnetism at the nanoscale: Electron spin resonance
(2021-05-12)
Scanning tunneling microscope (STM) lleva revolucionando el campo de la materia condensada desdehace unos años. Esta técnica ofrece tanto una gran resolución espacial como energética, permitiendo lamanipulación atómica ...
Evidence for a Spin Acoustic Surface Plasmon from Inelastic Atom Scattering
(Nature, 2021-01-15)
Closed-shell atoms scattered from a metal surface exchange energy and momentum with surface phonons mostly via the interposed surface valence electrons, i.e., via the creation of virtual electron-hole pairs. The latter can ...
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 ...
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 ...
