Modeling the Effect of Defects and Disorder in Amorphous Metal-Organic Frameworks. [PDF]

Chem Mater, 2022
Amorphous metal–organic frameworks (aMOFs) are a class of disordered framework materials with a defined local order given by the connectivity between inorganic nodes and organic linkers, but absent long-range order.

Packaging and delivering enzymes by amorphous metal-organic frameworks. [PDF]

Nat Commun, 2019
Enzymatic catalysis in living cells enables the in-situ detection of cellular metabolites in single cells, which could contribute to early diagnosis of diseases. In this study, enzyme is packaged in amorphous metal-organic frameworks (MOFs) via a one-pot

A method to quantify crystallinity in amorphous metal alloys: A differential scanning calorimetry study. [PDF]

PLoS One, 2020
We developed and describe a differential scanning calorimetry method for calculating the initial crystallinity, change of crystallinity and crystallinity percentage of amorphous metal alloys as a function of temperature. Using thermodynamic enthalpies of

Stöber method to amorphous metal-organic frameworks and coordination polymers

Nature Communications
The Stöber method is a widely-used sol-gel route for synthesizing amorphous SiO2 colloids and conformal coatings. However, the material systems compatible with this method are still limited.

Single‐element amorphous metals

Interdisciplinary Materials
To unveil the nature of amorphous states, single‐element amorphous metals have been the perfect research subject due to the simplest composition. However, the extreme crystal nucleation and growth rate in single‐element metal make the synthesis of single‐

Machine learning-based prediction of elastic properties of amorphous metal alloys [PDF]

Physica A: Statistical Mechanics and its Applications, 2023
The Young's modulus $E$ is the key mechanical property that determines the resistance of solids to tension/compression. In the present work, the correlation of the quantity $E$ with such characteristics as the total molar mass $M$ of alloy components ...

Topological Amorphous Metals [PDF]

Physical Review Letters, 2019
We study amorphous systems with completely random sites and find that, through constructing and exploring a concrete model Hamiltonian, such a system can host an exotic phase of topological amorphous metal in three dimensions. In contrast to the traditional Weyl semimetals, topological amorphous metals break translational symmetry, and thus cannot be ...
