Predicting metal-organic frameworks as catalysts to fix carbon dioxide to cyclic carbonate by machine learning

open access: yesJournal of Materiomics, 2021
The process of discovering and developing new materials currently requires considerable effort, time, and expense. Machine learning (ML) algorithms can potentially provide quick and accurate methods for screening new materials.

Extractability and mobility of mercury from agricultural soils surrounding industrial and mining contaminated areas [PDF]

open access: yes, 2010
This study focussed on a comparison of the extractability of mercury in soils with two different contamination sources (a chlor-alkali plant and mining activities) and on the evaluation of the influence of specific soil properties on the behaviour of the

Metal Oxide Chemiresistors: A Structural and Functional Comparison between Nanowires and Nanoparticles

open access: yesSensors, 2022
Metal oxide nanowires have become popular materials in gas sensing, and more generally in the field of electronic and optoelectronic devices. This is thanks to their unique structural and morphological features, namely their single-crystalline structure,

Metal-organic frameworks as selective or chiral oxidation catalysts [PDF]

open access: yes, 2014
Since the discovery of Metal Organic Frameworks (MOFs) in the early 1990s, the amount of new structures has grown exponentially. A MOF typically consists of inorganic nodes that are connected by organic linkers to form crystalline, highly porous ...

Development of a compact, IoT-enabled electronic nose for breath analysis [PDF]

open access: yes, 2020
In this paper, we report on an in-house developed electronic nose (E-nose) for use with breath analysis. The unit consists of an array of 10 micro-electro-mechanical systems (MEMS) metal oxide (MOX) gas sensors produced by seven manufacturers.

Double role of metalloporphyrins in catalytic bioinspired supramolecular metal–organic frameworks (SMOFs)

open access: yesIUCrJ, 2018
Heterogeneous catalysts are of great interest in many industrial processes for environmental reasons and, during recent years, a great effort has been devoted to obtain metal–organic frameworks (MOFs) with improved catalytic behaviour. Few supramolecular
