Engineering of Transmembrane Alkane Monooxygenases to Improve a Key Reaction Step in the Synthesis of Polymer Precursor Tulipalin A

open access: yesAngewandte Chemie International Edition, EarlyView.
A biosynthesis route for the polymer precursor tulipalin A starting from isoprenyl acetate is proposed. The alkane monooxygenase AlkB catalyzes the chemoselective terminal hydroxylation of isoprenyl acetate. Rational enzyme engineering further increased the activity of the membrane enzyme.

Valorization of CNSL as a Sustainable Solution for PVC Plasticization: A Comprehensive Study of Cardanol–Cardol Mixture

open access: yesJournal of the American Oil Chemists' Society, EarlyView.
ABSTRACT For the first time, a mixture of cardanol and cardol esters has been studied as plasticizers for PVC. From our previous work, it has been established that the favorable plasticizing properties of cardol for PVC materials exist. Hence, the utilization of cashew nutshell liquid (CNSL), a naturally occurring mixture of cardanol and cardol, as a ...

Improved Dewatering of Mature Fine Tailings Using High Molecular Weight Polyacrylamide Grafted From an Activated Carbon Surface by Surface‐Initiated ATRP

open access: yesJournal of Applied Polymer Science, Volume 142, Issue 22, June 10, 2025.
Efforts to address mature fine tailings in oil sand processing are advanced through the grafting of high molecular weight polyacrylamide onto activated carbon via surface‐initiated ATRP. Two grafting methods are compared, demonstrating improved dewatering performance with solids content increasing up to 50 wt%, offering a sustainable solution for ...

Production of a Polylactic Acid‐Based, Chitosan‐ and TiO2‐Modified Biodegradable Antimicrobial Coating Material and Investigation of Its Physical Properties

open access: yesJournal of Applied Polymer Science, EarlyView.
Biopolymer coating synthesized with PLA and TiO2 successfully shows a very good barrier property against water on paper. It is supported by SEM that the coating has a good surface appearance. ABSTRACT Polymer wastes are increasingly threatening the environment.

Topological Phase Transitions, Phase Diagrams, and Dielectric Properties of Pb(Zr0.7Ti0.3)O3‐Based Superlattices

open access: yesAdvanced Physics Research, EarlyView.
The phase‐field simulations are used to systematically calculate the phase diagrams of PZT/STO superlattices, considering various periodicities, strains, and temperatures. A rhombohedral‐type labyrinth domain oriented along the [110] direction is observed under low compressive strain. The dielectric responses for different polar topologies are examined,

A Needle in a Haystack: Landscape Survey and Archaeological Detection Experiments in Apalachee Bay

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT This paper presents the results of a pilot landscape‐scale seismic survey undertaken in Apalachee Bay, Florida, across a submerged landscape that contains dozens of Pre‐Contact sites. In addition to the goals of improving the geophysical and remote sensing ground model for this submerged landscape, the survey also sought to undertake the first

Remote Sensing Analysis and LiDAR Experimenting in the Espique Valley (La Peza, Granada, Spain)

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT The Espique valley is a small space at the foot of the mountain, practically closed, which hides a rich archaeological heritage, not only of habitats but also of varied productive spaces. For some years now, MEMOLab UGR has been carrying out research that is now enriched with the contribution of LiDAR, with whose application we are ...
