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

Journal 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

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.

Purification of Single-Wall carbon nanotubes by heat treatment and supercritical extraction

Materials Research, 2011
Arc discharge is the most practical method for the synthesis of single wall carbon nanotubes (SWCNT). However, the production of SWCNT by this technique has low selectivity and yield, requiring further purification steps.

Reframing FDI Motivations Through OLIP: Explaining Private Engagement for Sustainable Development in PPPs

Sustainable Development, EarlyView.
ABSTRACT The drivers of firms' participation in fragile markets have become increasingly complex. Under such conditions, the conventional explanation focusing on incentives within the OLI framework—ownership, location, and internalization advantages—proves insufficient.

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

Small, 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 ...

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 ...
