Orbital Hybridization‐Mediated Decoupling of Electrocatalytic Functions for Paired CO2 Electrosynthesis

open access: yesAdvanced Science, EarlyView.
This study constructs a dual‐scale Ag‐based catalyst on CeO2 nanorods via a facet‐guided strategy. This catalyst can induce a cascaded orbital hybridization effect, which synergistically optimizes oxygen vacancy stability, CO desorption kinetics, and charge transfer efficiency.

Molecular Bottom‐Up Design of Single‐Site Copper‐Palladium Catalysts for Selective Glycerol Electro‐Oxidation

open access: yesAdvanced Energy Materials, EarlyView.
A bimetallic Cu‐Pd single‐site catalyst for the selective and efficient electrooxidation of glycerol to formate and C3‐products (lactate, glycolate, glycerate) is reported. Experimental and theoretical studies shed light on the catalyst function and reveal that Pd sites facilitate the adsorption of hydroxyl (C‐OH) species which prevents C‐C bond ...

Dual Chemical Looping/Catalytic Process for Alkylation of Benzene With Ethane and Propane Yielding Ethylbenzene and Cumene Over Copper‐Containing Mordenite

open access: yesAngewandte Chemie, EarlyView.
We report a dual chemical looping/catalytic process coupling alkane dehydrogenation with aromatic alkylation over Cu‐mordenite, yielding up to 25% alkylated aromatics with >95% selectivity per cycle. In situ NMR, FTIR spectroscopy, and DFT show alkylation proceeds via a π‐bound Cu(I)–olefin intermediate and Brønsted acid sites.

SINGLE FACTOR STOCHASTIC MODELS WITH SEASONALITY APPLIED TO UNDERLYING WEATHER DERIVATIVES VARIABLES [PDF]

open access: yes
This paper estimates single factor stochastic models describing daily air temperature behaviour. We modify classical financial models to reflect temperature seasonality and fit them to a time series representing temperatures in Spain.

Breaking Down Lignin: A Macromolecule's Path to the Nanoscale

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
This section highlights lignin's critical role as a sustainable, multifunctional precursor for nanomaterial design. Its unique structure and abundance enable the creation of lignin‐based, lignin‐derived, and hybrid nanomaterials with tunable properties. Emphasis is placed on lignin's potential to drive innovation in nanotechnology, offering ecofriendly
