The work presents a combined study on the impact of cryogenic thermal cycling in terms differential scanning calorimetry measurements bulk metallic glasses and extensive molecular dynamics simulations generic model glass former.
This article describes advancements in the ongoing digital transformation materials science and engineering. It is driven by domain‐specific successes development of specialized data spaces. There an evident increasing need for standardization across various subdomains to support exchange entities. The MaterialDigital Initiative, funded German Federal Ministry Education Research, takes on a key role this context, fostering collaborative efforts establish unified space. implementation...
We investigate the effect of low temperature (cryogenic) thermal cycling on a generic model glass and observe signature rejuvenation in terms per-particle potential energy distributions. Most importantly, these distributions become broader its average values successively increase when applying consecutive cycles. show that linear dimension plays key role for effects to visible, since we do only weak cubic system roughly one hundred particle diameter but strong changes rule-type geometry with...
We investigate the effect of low temperature (cryogenic) thermal cycling on dynamics a generic model glass via molecular simulations. By calculating mean squared displacements after varying number cycles, pronounced enhancement is observed. This rejuvenation visible already first cycle and accumulates upon further in an intermittent way. Our data reveal overall deformation (buckling slab-shaped system) modulated by heterogeneous field due to deep cryogenic cycling. It shown strain maps that...
Through the use of silicon micromachining, micron dimensional features have been photolithographically patterned and subsequently etched bonded to generate three-dimensional microstructures which are incorporated into world's smallest fastest gas chromatograph (GC). The micromachined devices GC provide only commercially available components can match enhanced performance efficiency microbore (i.e., <or=100 mu m) fused silica capillary columns. It is noted that resulting high-speed micro-GC...
Via molecular dynamics simulations of a generic glass former in the supercooled and normal liquid states, it is shown that spatial correlations strain fluctuations exhibit crossover from well-established power-law ∼1/r3-decay at long wavelengths to an exponential behavior, ∼ intermediate distances. The characteristic length decay grows both with temperature time via, , being temperature-dependent diffusion coefficient. This suggests between decays governed by process.
