High‐Quality Epitaxial Five‐Layer Aurivillius Films with In‐Plane Ferroelectricity for Electrocaloric Cooling

Advanced Electronic Materials, Volume 11, Issue 11, July 2025.
High‐quality epitaxial five‐layer Sr2Bi4Ti5O18Aurivillius films are grown on SrTiO3 by pulsed laser deposition. The electrocaloric effect derived from measurements of the in‐plane ferroelectric polarization reveals a maximum temperature change of ΔT ∼ 0.95 °C under an electric field of 150 kV cm⁻¹ at 135 °C.

Improving the Efficiency of a Bioreactor Equipped With Mixed‐Flow Impellers

Chemical Engineering &Technology, Volume 48, Issue 7, July 2025.
The present work investigated the biological performance of mixed‐flow impellers. To the authors’ knowledge, this is the first experimental study on such impellers in a fermentation process using A. vinelandii, which was chosen as a microorganism due to its high oxygen demand.

Controlling Lampenflora in Heritage Sites: In Situ Testing of Polyoxometalate–Ionic Liquids in the Pommery Champagne Cellar

ChemPlusChem, Volume 90, Issue 7, July 2025.
The article evaluates polyoxometalate–ionic liquids (POM–ILs) as biocidal agents against lampenflora in the UNESCO‐listed Pommery Champagne cellar. POM–ILs effectively inhibit microbial colonization over one year with minimal visual impact and outperform the commercial biocide Preventol RI80.

New Insight on the Formation of Sodium Titanates 1D Nanostructures and Its Application on CO2 Hydrogenation

Frontiers in Chemistry, 2019
The aim of this work is focused on the study of a series of non-traditional catalytic nanomaterials to transform greenhouse CO2 gas into added-value products. We found encouraging results of CO2 hydrogenation activity over sodium titanates with different

Expression Profiles of Exosomal miRNAs in Gaucher Patients and Their Association With Severity of Bone Involvement

Journal of Inherited Metabolic Disease, Volume 48, Issue 4, July 2025.
ABSTRACT Bone manifestations are one of the most prevalent complications in patients with Gaucher disease (GD). Bone involvement is evaluated by using imaging methods, and there are different scores to assess its severity. However, there are no biomarkers that allow us to predict these manifestations.

Degradable Ureido‐Polycarbonate Block Copolymers with a Complex UCST Thermoresponse

Macromolecular Rapid Communications, Volume 46, Issue 14, July 18, 2025.
Amphiphilic block copolymers with degradable ureido‐functionalized polycarbonate segments self‐assemble into spherical micelles in water, exhibiting an intriguing upper critical solution temperature (UCST) behavior. Upon heating, these micelles swell, collapse, and reorganize into highly hydrated condensates that mimic polymeric nanogels.
