The Clean Water Initiative is underway!

Daniel T. Sun wins two grants, the SNF/Innosuisse’s Bridge Proof of Concept and EPFL’s Tech4Impact Playgrant, to develop next generation prototype filter devices. The objectives are the production of clean potable water and the selective extraction of highly valuable commodities. Congratulations! Shinzou wo Sasageyo!

JACS Young Investigators Virtual Issue 2019

The JACS paper about gold extraction using MOF/polymer composites has been featured in the 2019 JACS Young Investigators Virtual Issue.

 

We are excited and pleased to provide an ACS Select virtual issue based upon the outstanding work of young investigators published in 2018 in the Journal of the American Chemical Society. This collection of Articles and Communications highlights premier research in diverse topical areas from around the world that is of broad interest to the contemporary readership of JACS. These carefully selected publications were chosen by the appropriate, knowledgeable JACS Editors on the basis of reviewer input and editorial evaluation.

—Peter J. Stang, Editor-in-Chief

Prof. Omar Yaghi highlighted the work: “Gold extraction from wasted electronic devices is an important problem. Wendy Queen and co-workers report an Fe-MOF polymer composite capable of extracting ultratrace amounts of gold from wastewater, fresh water, ocean water, and solutions used to leach gold from electronic waste and sewage sludge ash. The MOF material has an exceptional removal capacity, 934 mg gold/g of composite, with high cyclability”.

Congratulations Daniel!

A Mystical material for seawater uranyl capture

A first reaction paper highlighting the work by Guangshan Zhu group is published in ACS Central Science.

The very smart design of MISS-PAF-1, which can extract 99.97% of uranyl from a 5 ppm solution in less than 120 min, relies on the encoding of very specific, directional interactions for uranyl ions inside the porous framework. The approach can be summarised in three steps: 1) mixing of uranyl ions with salicylaldoxime molecules to create a uranyl coordination complex having a predetermined configuration of oxime fragments, 2) grafting of the complex onto the internal surface of the PAF-1 template and 3) release of the uranyl species via treatment with sodium bicarbonate. The resulting modified material offers suitable anchors able to achieve a desired local bonding geometry that is specific to the uranyl ion. It should be noted that it is estimated that 4.5 billon tons of this commodity are found in the sea.

In this article, Daniel T. Sun and Wendy L. Queen also emphasise the evidences of climate change and the necessity to move to sustainable energy sources.

Organic polymer inside MOF channels preserves porosity

The work is just published in JACS.

LFIM reported a novel approach that allows mesoporous MOFs to prevent from collapsing thanks to the controlled polymerisation of dopamine monomers into their cavities. This strategy was proved useful for the MOF family M2(NDISA), where M = Ni2+, Co2+, Mg2+ and Zn2+, attaining surface areas 5, 24, 50 and 20 times higher, respectively, upon post-synthetic polymerisation. The polymer were also used to immobilise Pd nanocrystals, which led to outstanding performance in Suzuki–Miyaura cross-coupling.

Congratulations Li and Shuliang!
