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 ...

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 ...

Metal-organic frameworks (MOFs) offer great promise in a variety of gas- and liquid-phase separations. However, the excellent performance on the lab scale hardly translates into pilot- or industrial-scale applications due to the microcrystalline nature of ...

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 ...

With the ever-increasing production of electronics, there is an ensuing need for gold extraction from sources other than virgin mines. Currently, there are no technologies reported to date that can effectively and selectively concentrate ultratrace amounts ...

The present invention relates to a method for synthesis of a metal organic framework composite comprising the folowing steps: a) Synthesize a metal organic framework; b) Make a polymer grow on said metal organic framework, said polymer being chosen among p ...

Metal-organic frameworks are of interest in a number of host-guest applications. However, their weak coordination bonding often leads to instability in aqueous environments, particularly at extreme pH, and hence, is a challenging topic in the field. In thi ...

We report a one-step synthetic strategy to encapsulate copper nanocrystals (Cu NCs) in a carboxylate-based metal organic framework (MOF-74) to construct Cu@Cu-MOF-74 hybrids. One of the hurdles to realizing metal NC@MOF hybrids with uniform morphology and ...

The present invention concerns a perovskite solar cell provided with a polymer-porous template composite material for absorbing toxic metal ions. Preferably, the porous template material is a metal oxide framework (MOF) material. An example of a preferred ...

Aminated derivatives of 5-hydroxymethylfurfural (HMF) and furfural are critical intermediates for the pharmaceutical industry. The state-of-the-art catalysts currently used for these syntheses are mostly homogeneous in nature, motivating the design of recy ...

A double solvent method is for the first time used to synthesize a polymer composite that is constructed by a Ni-pyrazolate MOF and polydopamine (PDA). The resulting composite shows significantly enhanced water and CO2 adsorption properties compared to the ...

In this contribution, recent advances in the construction of MOF-polymer composites and their corresponding applications are briefly reviewed. The appearance of such architectures is becoming prominent in recent literature, due to the fact that the union o ...

he present invention relates to a composite for extracting one or more metal or contaminating chemical species from an aerial or aqueous medium by selective binding, said composite comprising at least one porous template functionalized by at least one poly ...

Transition-metal phosphides have received tremendous attention during the past few years because they are earth-abundant, cost-effective, and show outstanding catalytic performance in several electrochemically driven conversions including hydrogen evolutio ...

Drinking water contamination with heavy metals, particularly lead, is a persistent problem worldwide with grave public health consequences. Existing purification methods often cannot address this problem quickly and economically. Here we report a cheap, wa ...

Preventing the permeation of reactive molecules into electronic devices or photovoltaic modules is of great importance to ensure their life span and reliability. This work is focused on the formation of highly functioning barrier films based on nanocrystal ...

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 ...

MOF-derived Co3S4/CN hollow nanoboxes (CN=nitrogen-doped carbon) was used to catalyze the chemoselective reduction of nitroarenes to anilines under mild reaction conditions with H-2 as the reducing agent. The catalyst provides high conversion efficiencies ...
