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

open access: yesBatteries &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.

Multi‐Scale Investigation of Supramolecular Organogels Assembled From Pt(II)‐Salphen Complexes

open access: yesChemistry – A European Journal, EarlyView.
A family of Pt(II)‐salphen complexes with long alkyl chains is investigated as low‐molecular‐weight organogelators. Multi‐scale characterization of their supramolecular gels reveals how the chain length, Pt‐Pt interactions, and π–π stacking direct self‐assembly and tune gel mechanics.

Origin of the Springback Effect in Ambient-Pressure-Dried Silica Aerogels: The Effect of Surface Silylation

open access: yesGels, 2023
Ambient pressure drying (APD) can prospectively reduce the costs of aerogel fabrication and processing. APD relies solely on preventing shrinkage or making it reversible.

Electrospun fibrous sorbents for the removal of uranium and americium from aqueous media

open access: yesPolymer International, EarlyView.
Polymethacrylate‐based electrospun microfibers with tertiary amino functionalities are evaluated as adsorbents for U‐232 and Am‐241 in both simplified and complex (seawater) water matrices, highlighting their ability for efficient actinide removal. Abstract Polymethacrylate‐based electrospun microfibers containing tertiary amino functionalities were ...
