Zirconia as a support for catalysts: influence of additives on the thermal stability of the porous texture of monoclinic zirconia [PDF]

open access: yes, 1991
A single-phase monoclinic zirconia (the thermodynamically stable modification up to a temperature of 1170°C), having a specific surface area of 67 m2g¿1 and a well-developed mesoporous texture, has been prepared by gel-precipitation followed by ...

The Bulk Channel in Thermal Gauge Theories [PDF]

open access: yes, 2010
We investigate the thermal correlator of the trace of the energy-momentum tensor in the SU(3) Yang-Mills theory. Our goal is to constrain the spectral function in that channel, whose low-frequency part determines the bulk viscosity.

Chemical Composition and Color of Short-Rotation Teak Wood Thermally Modified in Closed and Open Systems

open access: yesApplied Sciences, 2023
Although the effect of thermal modification (TM) on teak wood color is well documented, few studies have been carried out on closed-system processes, and it remains unclear what the effect is of different processes on the same material.

Morphology and properties evolution upon ring-opening polymerization during extrusion of cyclic butylene terephthalate and graphene-related-materials into thermally conductive nanocomposites [PDF]

open access: yes, 2017
In this work, the study of thermal conductivity before and after in-situ ring-opening polymerization of cyclic butylene terephthalate into poly (butylene terephthalate) in presence of graphene-related materials (GRM) is addressed, to gain insight in the ...

Thermal Interface Conductance between Aluminum and Silicon by Molecular Dynamics Simulations [PDF]

open access: yes, 2014
The thermal interface conductance between Al and Si was simulated by a non-equilibrium molecular dynamics method. In the simulations, the coupling between electrons and phonons in Al are considered by using a stochastic force.

Holographic Interferometry for Measuring the Effect of Thermal Modification on Wood Thermal Properties

open access: yesApplied Sciences, 2021
The paper focuses on the use of holographic interferometry in the research of thermal modification and its effect on the heat transfer from the wood surface to the surrounding air. In the experiment, spruce wood samples modified at 160 °C, 180 °C, 200 °C,

Microscopic theory of the pseudogap and Peierls transition in quasi-one-dimensional materials [PDF]

open access: yes, 1995
The problem of deriving from microscopic theory a Ginzburg-Landau free energy functional to describe the Peierls or charge-density-wave transition in quasi-one-dimensional materials is considered.

Butterflies from Information Metric [PDF]

open access: yes, 2016
We study time evolution of distance between thermal states excited by local operators, with different external couplings. We find that growth of the distance implies growth of commutators of operators, signifying the local excitations are scrambled.
