A customized MOF-polymer composite for rapid gold extraction from water matrices

Wendy Lee Queen, Daniel Teav Sun, Shuliang Yang, Jun Li, Li Peng, Olga Syzgantseva

With the fast-growing accumulation of electronic waste and rising demand for rare metals, it is compelling to develop technologies that can promotionally recover targeted metals, like gold, from waste, a process referred to as urban mining. Thus, there is ...

An Investigation into the Intrinsic Peroxidase-Like Activity of Fe-MOFs and Fe-MOFs/Polymer Composites

Wendy Lee Queen, Daniel Teav Sun, Vikram Vinayak Karve

The quest for developing materials that provide a perfect trade-off between factors such as enzyme-like response, stability, and low cost has been a long-standing challenge in the field of biosensing. Metal-organic frameworks (MOFs) and their composites ha ...

A metal-organic framework/polymer derived catalyst containing single-atom nickel species for electrocatalysis

Wendy Lee Queen, Emad Oveisi, Wen Luo, Daniel Teav Sun, Shuliang Yang, Li Peng, Jie Zhang, Mehrdad Asgari, Olga Trukhina, Dragos-Constantin Stoian

While metal-organic frameworks (MOF) alone offer a wide range of structural tunability, the formation of composites, through the introduction of other non-native species, like polymers, can further broaden their structure/property spectrum. Here we demonst ...

Evaluation of materials for iodine and technetium immobilization through sorption and redox-driven processes

Wendy Lee Queen, Daniel Teav Sun

Radioactive iodine-129 (I-129) and technetium-99 (Tc-9(9)) pose a risk to groundwater due to their long half-lives, toxicity, and high environmental mobility. Based on literature reviewed in Moore et al. (2019) and Pearce et aL (2019), natural and engineer ...

Construction of MOF/Polymer Composites for Metal Ion Capture

Daniel Teav Sun

Metal ion capture is of environmental and economic significance. The industrial revolutions have discharged increasing amounts of heavy and precious metals into complex water sources. The key is that these types of metal ions tend to be at trace amounts in ...
