Creep compression behaviour of a polyurethane foam from cryogenic temperatures: size effect and long-term prediction

open access: yesEPJ Web of Conferences, 2010
The objective of this work was to predict the long term behavior of Polyurethane foam (PU) at very low-temperature, by applying the time-temperature superposition principle (TTSP).

An equation for bolt clampup relaxation in transient environments [PDF]

open access: yes
An equation for bolt clampup relaxation for transient temperature-moisture (T-M) conditions was derived starting with a relaxation equation for steady-state conditions, and then using an incremental time approach that exploits the superposition principle

Coupled thermo mechanical characterisation of polymers based on inverse analyses and IR measurements

open access: yes, 2011
International audienceHeat dissipation during mechanical testing can disturb experimental characterisation of polymers. In this work it is demonstrated that these effects are not limited to extreme loading conditions such as impacts. A visco-hyperelastic,

Correlating the Photoshunt with Charge‐Collection Losses in Organic Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
Quantifying charge extraction losses in organic solar cells is crucial for understanding the origin of power losses and, consequently, for improving the performance. An analytical framework is presented that utilizes a readily available observable photoshunt and its correlation with light intensities for evaluating charge transport properties of a ...

A novel semi-analytical methodology for predicting sound absorption of anechoic coatings with arbitrary rotary cavities dependent on temperature and frequency

open access: yesResults in Physics, 2021
In response to the shortcomings of existing studies on the sound-absorbing characteristics of an anechoic coating, which most ignore the frequency factor and are expensive for temperature-tunable hydroacoustic experiments, a novel semi-analytical ...

Zinc Grid Based Transparent Electrodes for Organic Photovoltaics

open access: yesAdvanced Energy Materials, EarlyView.
A transparent flexible electrode based on an embedded zinc grid with ≈1 µm linewidth is reported, and its utility as a drop‐in replacement for indium‐tin oxide coated glass electrodes in organic photovoltaic devices is demonstrated. The zinc grids are fabricated using the unconventional approach of condensation coefficient modulation, using a ...

Thermodynamic Scaling of the Dynamics of a Strongly Hydrogen-Bonded Glass-Former

open access: yesScientific Reports, 2017
We probe the temperature- and pressure-dependent specific volume (v) and dipolar dynamics of the amorphous phase (in both the supercooled liquid and glass states) of the ternidazole drug (TDZ). Three molecular dynamic processes are identified by means of

Ion‐Anchoring Dipole‐Integrated Composite Elastomer Electrolyte and Cathode for High‐Performance Lithium Metal Batteries via Multiple‐Bridge Engineering

open access: yesAdvanced Energy Materials, EarlyView.
The multiple‐bridge engineered composite elastomer electrolyte enhances Li+ transport through ion‐rotating and ion‐anchoring dipole interactions, as well as hydrogen bonding, improving conductivity and promoting uniform Li+ deposition. The composite elastomer cathode improves interfacial stability, resulting in excellent cycling stability in lithium ...

Memory and superposition in a spin glass

open access: yes, 2000
Non-equilibrium dynamics in a Ag(Mn) spin glass are investigated by measurements of the temperature dependence of the remanent magnetisation. Using specific cooling protocols before recording the thermo- or isothermal remanent magnetisations on re ...
