New sustainable catalyst: Fast, selective, reductive conversion of CO2!

webfull — Tue, 24 Sep 2024 18:48:36 +0000

Anthropogenic climate change drastically affects our planet, with CO₂ being the most critical gaseous driver. Here, we present a fast, effective, and sustainable route for coupling diverse alcohols, amines and amides with CO₂ via heterogenization of a natural metal-based homogeneous catalyst through decorating on functionalized graphene oxide. Combined synthetic, experimental, and theoretical studies unravel mechanistic routes to convergent 4‑electron reduction of CO₂ under mild conditions.

Dr. Seyed Mohammad Amin Ojagh, from Prof. van de Ven's research group and his colleagues, introduced a novel class of highly functionalized nanocellulose-based materials for diverse applications, recently published in the Chemical Engineering Journal. This study involved the in-situ modification of bacterial cellulose (BC) with hairy nanocellulose (HNC), resulting in nanocomposites with enhanced physicochemical properties compared to BC alone.

Nanoplastics in Water: Artificial Intelligence-Assisted 4D Physicochemical Characterization and Rapid In Situ Detection

webfull — Tue, 07 May 2024 13:28:13 +0000

For the first time, The Ariya lab present a much-needed technology for the in situ and real-time detection of nanoplastics in aquatic systems.
We show an artificial intelligence-assisted nanodigital in-line holographic microscopy (AI-assisted nano-DIHM) that automatically classifies nano- and microplastics simultaneously from nonplastic particles within milliseconds in stationary and dynamic natural waters, without sample preparation.

Phenols are a common functional group of many naturally occurring and biologically active molecules, including many that are part of the human diet. In 2020 alone, ~60% of small molecule drugs approved by the FDA contained a phenol or a closely related phenolic ether, underscoring their importance to the pharmaceutical industry.
