Molecular imine cages with π-basic Au3(pyrazolate) faces

Rosario Scopelliti, Kay Severin, Farzaneh Fadaei Tirani, Noga Eren

One tetrahedral and two trigonal prismatic cages with π-basic Au3(pyrazolate)3 faces were obtained by connection of pre-formed gold complexes via dynamic covalent imine chemistry. The parallel arrangement of the Au3(pyrazolate)3 complexes in the prismatic ...

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 ...

Operando diffuse reflectance infrared detection of cyanide intermediate species during the reaction of formaldehyde with ammonia over V2O(5)/ WO3-TiO2

Davide Ferri, Oliver Kröcher, Rob Jeremiah G. Nuguid

Hydrogen cyanide (HCN) is a highly poisonous gas that can form through the reaction between formaldehyde and ammonia (NH3) in the exhaust. While this detrimental side reaction has been the subject of recent catalytic studies under selective catalytic reduc ...

Gas-Phase Ozone Reactions with a Structurally Diverse Set of Molecules: Barrier Heights and Reaction Energies Evaluated by Coupled Cluster and Density Functional Theory Calculations

Jeremy Samuel Arey, Peter Rudolf Tentscher, Daniela Trogolo

Reactions with ozone transform organic and inorganic molecules in water treatment systems as well as in atmospheric chemistry, either in the aqueous phase, at gas/particle interfaces, or in the gas phase. Computed thermokinetic data can be used to estimate ...

Rapid, Selective Extraction of Trace Amounts of Gold from Complex Water Mixtures with a Metal-Organic Framework (MOF)/Polymer Composite

Wendy Lee Queen, Emad Oveisi, Natalia Gasilova, Daniel Teav Sun, Shuliang Yang

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 ...

CRADLE TO CRADLE® - PARQUET FOR GENERATIONS RESPECT FOR RESOURCES AND PRESERVATION FOR FUTURE

Working with wood means assuming a responsibility. Wood is the most important naturally re- growing raw material and it is considered to be the construction material of the future. However, treated with chemicals (adhesives, lacquers) the resource wood bec ...

Dimensional effects on the tunneling conductivity of gold-implanted nanocomposite films

Claudio Grimaldi

We study the dependence of the electrical conductivity on the gold concentration of Au-implanted polymethylmethacrylate (PMMA) and alumina nanocomposite thin films. For Au contents larger than a critical concentration, the conductivity of Au-PMMA and Au-al ...

Synthesis and Reactivity of Mononuclear Iron Models of [Fe]-Hydrogenase that Contain an Acylmethylpyridinol Ligand

Xile Hu, Dafa Chen, Bowen Hu

[Fe]-hydrogenase has a single iron-containing active site that features an acylmethylpyridinol ligand. This unique ligand environment had yet to be reproduced in synthetic models; however the synthesis and reactivity of a new class of small molecule mimics ...
