Excited-state band structure mapping
(American Physical Society, 2022-02-15)
[EN] Angle-resolved photoelectron spectroscopy is an extremely powerful probe of materials to access the occupied electronic structure with energy and momentum resolution. However, it remains blind to those dynamic states ...
Surface Roughness Enhances Self-Nucleation of High-Density Polyethylene Droplets Dispersed within Immiscible Blends
(American Chemical Society, 2022)
[EN] Highly linear or high-density polyethylenes (HDPEs) have an intrinsically high nucleation density compared to other polyolefins. Enhancing their nucleation density by self-nucleation is therefore difficult, leading ...
Nanometer-Scale Lateral p–n Junctions in Graphene/α-RuCl3 Heterostructures
(American Chemical Society, 2022)
[EN] The ability to create nanometer-scale lateral p-n junctions is essential for the next generation of two-dimensional (2D) devices. Using the charge-transfer heterostructure graphene/alpha-RuCl3, we realize nanoscale ...
Probing phonon dynamics with multidimensional high harmonic carrier-envelope-phase spectroscopy
(National Academy of Sciences, 2022-06)
We explore pump-probe high harmonic generation (HHG) from monolayer hexagonalboron-nitride, where a terahertz pump excites coherent optical phonons that are subsequently probed by an intense infrared pulse that drives HHG. ...
Photoactive Platinum(II) Azopyridine Complexes
(Wiley, 2022-01)
Platinum(II) complexes containing the strong pi-acceptor N,N-chelating ligand phenylazopyridine (Ph-azpy) [Pt(p-R-Ph-azpy)X2 ], R = H, NMe2 or OH, X = Cl or N3 , have been synthesized and characterized to explore the effects ...
Comment on "Anomalous structural recovery in the near glass transition range in a polymer glass: Data revisited in light of temperature variability in vacuum oven-based experiments"
(Wiley, 2022-08)
Recent efforts, fostered by a pioneering work by us, have shown the of multiple steps in the recovery of equilibrium of glasses. Jin and McKenna raise concerns regarding the validity of such scenario alleging that the ...
Effect of the TrFE Content on the Crystallization and SSA Thermal Fractionation of P(VDF-co-TrFE) Copolymers
(MDPI, 2022-09-08)
In this contribution, we study the effect of trifluoro ethylene (TrFE) comonomer content (samples with 80/20, 75/25, and 70/30 VDF/TrFE molar ratios were used) on the crystallization in P(VDF-co-TrFE) in comparison with a ...
Pi-magnetism and quantum transport in graphene-based nanostructures
(2022-10-21)
El grafeno constituye un material idóneo para aplicaciones electrónicas, sin embargo, al no poseer un gapen la estructura de bandas, este material dos-dimensional no puede utilizarse para construir la arquitecturadel ...
Characterization and Modification of Red Mud and Ferrosilicomanganese Fines and Their Application in the Synthesis of Hybrid Hydrogels
(MDPI, 2022-10-14)
In this work, hybrid hydrogels were synthesized with the inclusion of two types of clay materials that are considered industrial waste: red mud (RM) and ferrosilicomanganese fines (FeSiMn). These solid waste materials were ...
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 ...
