Topologically Optimized Cast Glass: A New Design Approach for Loadbearing Monolithic Glass Components of Reduced Annealing Time

open access: yesChallenging Glass Conference Proceedings, 2022
Up to now, fabricating cast glass components of substantial mass and/or thickness involves a lengthy and perplex annealing process. This has limited the use of this glass manufacturing method in the built environment to simple objects up to the size of ...

Enzymatic degradation of biopolymers in amorphous and molten states: mechanisms and applications

open access: yesFEBS Open Bio, EarlyView.
This review explains how polymer morphology and thermal state shape enzymatic degradation pathways, comparing amorphous and molten biopolymer structures. By integrating structure–reactivity principles with insights from thermodynamics and enzyme engineering, it highlights mechanisms that enable efficient polymer breakdown.

Unveiling the structural arrangements responsible for the atomic dynamics in metallic glasses during physical aging

open access: yesNature Communications, 2016
Glass aging is one of unsolved problems during glass processing and annealing, partly due to the lack of the mechanistic understanding on microscales. Here, the authors show how local stresses and their evolution affect structural relaxation at an atomic

Measuring free energy in parallel tempering Monte Carlo

open access: yes, 2015
An efficient approach of measuring the absolute free energy in parallel tempering Monte Carlo using the exponential averaging method is discussed and the results are compared with those of population annealing Monte Carlo using the three-dimensional ...

Disorder-to-order transition in the magnetic and electronic properties of URh_2Ge_2 [PDF]

open access: yes, 1999
We present a study of annealing effects on the physical properties of tetragonal single--crystalline URh_2Ge_2. This system, which in as-grown form was recently established as the first metallic 3D random-bond heavy-fermion spin glass, is transformed by ...

Revisiting Stability Criteria in Ball‐Milled High‐Entropy Alloys: Do Hume–Rothery and Thermodynamic Rules Equally Apply?

open access: yesAdvanced Engineering Materials, Volume 27, Issue 6, March 2025.
The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

Characterization and Conduction Mechanism of Highly Conductive Vanadate Glass

open access: yesCroatica Chemica Acta, 2015
This paper reviews recent studies of highly conductive barium iron vanadate glass with a composition of 20 BaO ∙ 10 Fe2O3 ∙ 70 V2O5 (in mol %). Isothermal annealing of the vanadate glass for several ten minutes at a given temperature, higher than glass ...

Optimised simulated annealing for Ising spin glasses [PDF]

open access: yesComputer Physics Communications, 2015
We present several efficient implementations of the simulated annealing algorithm for Ising spin glasses on sparse graphs. In particular, we provide a generic code for any choice of couplings, an optimized code for bipartite graphs, and highly optimized implementations using multi-spin coding for graphs with small maximum degree and discrete couplings ...
