Shelf-Life Prediction of Shallot Powder Using Accelerated Shelf-Life Testing (ASLT) Method by the Arrhenius Equation Approach

open access: yesIndustria: Jurnal Teknologi dan Manajemen Agroindustri, 2022
The storage process of shallot powder can cause a quality decrease. This study aims to estimate shelf-life of shallot powder at various storage temperatures and determine quality changes during storage. This study used a Completely Randomized Design with

No-pumping theorem for non-Arrhenius rates

open access: yes, 2017
The no-pumping theorem refers to a Markov system that holds the detailed balance, but is subject to a time-periodic external field. It states that the time-averaged probability currents nullify in the steady periodic (Floquet) state, provided that the ...

Predictions of Dynamic Behavior Under Pressure for Two Scenarios to Explain Water Anomalies [PDF]

open access: yes, 2007
Using Monte Carlo simulations and mean field calculations for a cell model of water we find a dynamic crossover in the orientational correlation time $\tau$ from non-Arrhenius behavior at high temperatures to Arrhenius behavior at low temperatures.

Electrical Conductivities of Conductors, Semiconductors, and Their Mixtures at Elevated Temperatures

open access: yesAdvanced Engineering Materials, EarlyView.
This article presents a comprehensive review of temperature‐dependent electrical conductivity data for multiple material classes at elevated temperatures, highlighting a persistent conductivity gap between metals and semiconductors in the range of 102$\left(10\right)^{2}$– 107$\left(10\right)^{7}$ S/m. Metal–ceramic irregular metamaterials are proposed

Iridium-catalyzed enantioconvergent hydrogenation of trisubstituted olefins

open access: yesNature Communications, 2022
Usually asymmetric hydrogenation of olefins is enantiodivergent and thus requires isomerically pure olefins, which is a considerable drawback. Here, the authors show a general iridium-catalyzed enantioconvergent hydrogenation of a broad range of ...

Temperature-Dependent Activity of Motor Proteins: Energetics and Their Implications for Collective Behavior

open access: yesFrontiers in Cell and Developmental Biology, 2021
Molecular motor proteins are an extremely important component of the cellular transport system that harness chemical energy derived from ATP hydrolysis to carry out directed mechanical motion inside the cells. Transport properties of these motors such as

Rafting of Ni‐Based Superalloys Under Multiaxial Load as Understood by Phase‐Field Simulations and Critical Experiments

open access: yesAdvanced Engineering Materials, EarlyView.
Phase‐field simulations coupled with dislocation‐density‐based crystal plasticity modeling reproduce γ′ rafting behavior in single‐crystal Ni‐based superalloys under varied loading conditions. The model captures both macroscopic creep and microscopic morphology evolution, with results matching high‐temperature creep experiments.

Why are glass-forming liquids non-Arrhenius?

open access: yes, 1997
A major mystery of glass-forming liquids is the non-Arrhenius temperature-dependence of the average relaxation time. This paper briefly reviews the classical phenomenological models for this phenomenon - the free-volume model and the entropy model - and ...
