Synergetic Combination of Carbon Xerogels, Graphene Oxide and nano‐ZnO for Aqueous and Organic Supercapacitors

Batteries &Supercaps, Volume 8, Issue 3, March 2025.
This work proposes the synthesis of carbon‐based nanostructured materials obtained using ZnO as both nanos‐ template and catalysts simultaneously. During the synthesis, GO was used as a stabiliser, preventing the collapse of the 3D structure and improving its properties in terms of capacitance and surface area.

WSPLK: A systematic approach to the thermodynamic characterization of light and heavy Mexican crude oil

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract A streamlined characterization framework (WSPLK) is presented for modelling complex reservoir fluids using cubic equations of state. The key methodological contribution is the introduction of a single global parameter ε directly into Pedersen's boiling‐point correlation, restoring pure‐component calibration and eliminating the need for ...

Dinuclear Rhodium(I)–N‐Heterocyclic Carbene Complexes as Alkyne Hydropyridonation Catalysts

European Journal of Inorganic Chemistry, EarlyView.
Catalyst Improvement by NHC tuning: A series of new RhI–NHC dinuclear complexes has been revealed as efficient alkyne hydropyridonation catalysts. 333053IMes complex displays the highest reactivity of the series, suggesting that a moderate steric demand combined with balanced σ‐donation facilitates precatalyst activation and substrate exchange.

Gender Mainstreaming in Urban Food Policies: Governance Processes and Policy Designs From Three Spanish Cities

European Policy Analysis, EarlyView.
ABSTRACT This paper explores the integration of gender mainstreaming in urban food policies (UFPs) through three Spanish case studies: Barcelona, Valencia, and Zaragoza. While UFPs are pivotal for addressing sustainability in urban food systems, attention to gender disparities within them remains insufficient.
