Estimation of Total Phenols, Flavanols and Extractability of Phenolic Compounds in Grape Seeds Using Vibrational Spectroscopy and Chemometric Tools [PDF]

open access: yes, 2018
Near infrared hyperspectral data were collected for 200 Syrah and Tempranillo grape seed samples. Next, a sample selection was carried out and the phenolic content of these samples was determined.

2D Co‐Mo‐Hydroxide‐Based Multifunctional Material for the Development of H2‐Based Clean Energy Technologies

open access: yesAdvanced Materials, EarlyView.
2D α‐Co(OH)2 interleaved with Mo species displays an appealing dual functionality for the production and use of green hydrogen.Mo incorporation greatly benefits the electrochemical behaviour in Oxygen Evolution Reaction for H2 production, while the magnetocaloric response at liquid H2 temperature paves the way for alternative cryogenic refrigerants ...

Enhanced mitochondrial activity reshapes a gut microbiota profile that delays NASH progression

open access: yesHepatology, EarlyView., 2022
Improved mitochondrial activity, due to the lack of methylation‐controlled J protein (MCJ), creates a specific microbiota signature that when transferred through cecal microbiota transplantation delays NASH progression by restoring the gut‐liver axis and enhancing hepatic fatty acid oxidation.

REPARABLE, ACTUALIZABLE Y RECICLABLE. LA ECONOMÍA CIRCULAR, COMO NUEVO MODELO ECONÓMICO SUSTENTABLE EN MÉXICO (Cartel) [PDF]

open access: yes, 2018
La economía lineal es decir “el Tomar, Hacer, Desechar” es el modelo de producción por la cual hoy por hoy se rigen los sistemas económicos. Pero ¿Este modelo sigue siendo funcional? Existen diferentes posturas las cuales son debatibles, pero hay algo en

High Light Utilization and Color Rendering in Vacuum‐Deposited Semitransparent Perovskite Solar Cells

open access: yesAdvanced Materials, EarlyView.
In this work, low bandgap (≈1.55 eV) semitransparent perovskite solar cells (ST‐PSCs) having thin (thickness < ≈100 nm) perovskite layers and transparent conductive oxide‐based rear electrodes are fabricated using vacuum‐deposition methods. Two different ST‐PSCs demonstrated a high light utilization efficiency value of 4.2 (PCE: 9.26% and AVT: 45.3 ...

La fiscalidad ambiental en materia de residuos en el marco de una economía circular

open access: yesCrónica Tributaria, 2019
La fiscalidad ambiental es una de las herramientas que, sin duda, ha demostrado una mayor eficacia para la protección del medio ambiente, en particular respecto al sector de los residuos, y al mismo tiempo también puede jugar un papel esencial en el ...

Spin‐Split Edge States in Metal‐Supported Graphene Nanoislands Obtained by CVD

open access: yesAdvanced Materials, EarlyView.
Combining STM measurements and ab‐initio calculations, we show that zig‐zag edges in graphene nanoislands grown on Ni(111) by CVD retrieve their spin‐polarized edge states after intercalation of a few monolayers of Au. ABSTRACT Spin‐split states localized on zigzag edges have been predicted for different free‐standing graphene nanostructures.

Flexoelectrically Induced Polar Topology in Twisted SrTiO3 Membranes

open access: yesAdvanced Materials, EarlyView.
Twisted SrTiO3 bilayers host polar vortices of flexoelectric origin, revealed through combined experiment and theory. By reconstructing polarization from the toroidal moment of strain gradients, the work establishes a 3D chiral state with broken inversion and mirror symmetries.

Atomistic Mechanisms Triggered by Joule Heating Effects in Metallic Cu‐Bi Nanowires for Spintronics

open access: yesAdvanced Materials, EarlyView.
Bi doped metallic Cu nanowires are promising for spintronics thanks to the stabilization of a giant spin Hall effect. However, heat resulting from current injection forces Bi to leave solution, forcing segregation into monoatomic decorations which evolve into coherent crystalline aggregates.
