Copolymer Synthesis of N‐Vinylacetamide and 2‐Methylene‐1,3‐Dioxepane Provides a New Degradable Polymer

open access: yesJournal of Polymer Science, Volume 63, Issue 6, Page 1306-1318, 15 March 2025.
ABSTRACT N‐vinylamides, especially noncyclic N‐vinylacetamide (NVA), have been used in various applications such as biomaterials, surfactants, and hydrogels. However, their potential to copolymerize with cyclic ketene acetal (CKA) to create degradable polymers is underexplored.

The continuing significance of chiral agrochemicals

open access: yesPest 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.

3D‐Printed Crosslinked Nanocellulose‐MXene Hydrogels and Aerogels with High Strength and Conductivity

open access: yesSmall, EarlyView.
This study presents a robust strategy for 3D printing conductive, mechanically resilient MXene–CNF composite structures using a single‐step freeze‐induced crosslinking method. The printed architectures remain stable in both wet and dry states, exhibit high electrical conductivity and mechanical strength, and demonstrate practical application in fully ...

Supercritical-fluid extraction of oil-palm components

open access: yes, 1995
Residue from the mechanical processing of palm oil was treated with supercritical-fluid extraction (SFE) to extract carotenes. This was done at different extraction conditions.

Solar‐Powered Water Depollution Through a Bioinspired Device Based on ZIF‐8 Loaded Macroporous Hydrogels Prepared via Ice‐Templating

open access: yesSmall, EarlyView.
ABSTRACT Water pollution poses a constant threat to the environment and is one of the central causes for global shortage of clean water. Metal–Organic Frameworks (MOFs) have emerged as highly efficient adsorbents; however, their application is limited by their common production as fine powders, which hinders recovery and reuse.

A Versatile Heterometallic Microporous MOF for Photocatalytic Hydrogen Generation

open access: yesSmall, 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 ...

Characterization of the Pore Environments in Covalent Organic Frameworks by Dynamic Spin Probe Exchange

open access: yesSmall, EarlyView.
Covalent organic frameworks (COFs) with alkyl or triethylene glycol pore linings are probed with water‐dissolved nitroxide radicals using CW EPR spectroscopy. Adsorption affinity, local polarity, and radical concentration inside the pores are quantified, revealing hydrogen bonding, dipolar, and π‐π interactions that govern guest binding, which ...

Integrated Experimental, Chemometric, and In Silico Analyses of Larvicidal Supercritical Extracts From Myrtaceae Species Against Aedes aegypti. [PDF]

open access: yesChem Biodivers
The cross‐validated regression tree showed modest predictive performance. Mortality was not significantly associated with the first two PCA axes. Molecular modeling generated testable ligand–target hypotheses. Psidium cattleianum had lower LD50. The larvicidal activity of the crude extracts could not be attributed to individual constituents.

Porous biomaterials by using supercritical fluids emulsions

open access: yes, 2006
Different authors have investigated the production of porous polymeric materials using supercritical CO2 as a solvent and/or foaming agent. The removal of the template phase is simple since CO2 reverts to gas phase upon depressurization.
