The Effect of the Aging Process of Polyamide 11 Used in Flexible Pipelines and Its Influence on the Permeability of Carbon Dioxide

Polymer Engineering &Science, EarlyView.
Field degradation inducing changes in the Polyamide 11 permeability. ABSTRACT This study investigates how long‐term natural aging affects the CO2 permeability of polyamide 11 (PA11) pressure sheaths recovered from decommissioned flexible risers. PA11 samples were extracted from two 18‐year‐old risers—a gas‐lift line and an oil‐production line—and ...

The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Theoretical framework for updating cross‐sections in river models using non‐standard information coming from crowdsourced images

River, EarlyView.
Abstract During high rainfall events, one reason for flooding in urban rivers is hydraulic blockages or obstructions in channels. These may cause damming and an immediate increase in upstream water levels, leading to inundation of surroundings. The accuracy of flood models is strongly dependent on the representation of the topography of floodplain and ...

A Versatile Heterometallic Microporous MOF for Photocatalytic Hydrogen Generation

Small, EarlyView.
This work describes a green and scalable approach to robust and flexible heterometallic MOFs, MIP‐215's, with tunable photoactivity for efficient, noble‐metal‐free solar hydrogen production. ABSTRACT Photocatalytic particulate systems offer a cost‐effective solar hydrogen production but are generally limited by narrow visiblelight absorption and poor ...

Adsorption equilibria of benzoic acid on silica gel from supercritical carbon dioxide

, 2010
Supercritical fluids, especially carbon dioxide, are increasingly used as carriers for adsorption-desorption processes, particularly in the pharmaceutical industry. Nevertheless, equilibria data for such processes are rather limited.

Organic reactions in supercritical fluids: Continuous, selective, and green.

, 1999
Supercritical fluids (SCFs) offer a wide range of opportunities as media for chemical reactions and supercritical CO2, ScCO2, is becoming increasingly important as a benign replacement for more toxic solvents.1 High pressure reactions, however, are more ...

One‐Pot Fabrication of Pentapeptide Bio‐Aerogel via Direct Alcogelation

Small, EarlyView.
A minimal tachykinin‐inspired pentapeptide (TC‐1) self‐assembles in water and ethanol to form robust gels that can be dried in one pot to ultra‐porous aerogels using supercritical carbon dioxide. Solvent choice programs nanoscale packing and bulk mechanics producing lightweight monoliths with high porosity for biomaterials applications, verified by ...
