Thermodynamics of DNA: heat capacity changes on duplex unfolding

open access: yesEuropean Biophysics Journal, 2019
The heat capacity change, ΔCp, accompanying the folding/unfolding of macromolecules reflects their changing state of hydration. Thermal denaturation of the DNA duplex is characterized by an increase in ΔCp but of much lower magnitude than observed for ...

Assessing the Microstructure of SnBiZn Alloys during Semisolid Treatment

open access: yesAdvanced Engineering Materials, EarlyView.
The development of Sn‐based alloys for semisolid processing is crucial for Industry 4.0. This study investigates Sn40Bi and Sn40Bi2Zn alloys, revealing that Zn refines Sn‐rich globules by pinning dendrite boundaries. Bi saturation occurs at 60 min, while Zn enhances globule microhardness at 90 min through solid solution strengthening.

Timelike Boundary Sine-Gordon Theory and Two-Component Plasma

open access: yes, 2007
It has long been known that there is a relation between boundary sine-Gordon theory and thermodynamics of charge neutral two-component Coulomb plasma on a unit circle.

Modified theory of gravity and clustering of multi-component system of galaxies

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
In this paper, we analyze the clustering of galaxies using a modified theory of gravity, in which the field content of general relativity has been be increased.

Mechanical Behavior and Microstructural Changes Associated with Tensile Deformation above the Martensite Start Temperature during Quenching and Subsequent Partitioning of a Low‐Alloy 37SiB6 Steel

open access: yesAdvanced Engineering Materials, EarlyView.
A new experimental setup, incorporating digital image correlation and infrared thermography in combination with inductive‐conductive heating for precise temperature control, is used to analyze the mechanical behavior and microstructural changes of sheet metal under complex thermomechanical test conditions that represent quench and partitioning ...

Interacting two-component fluid models with varying EoS parameter

open access: yes, 2014
In this paper, we consider Universe filled with two-component fluid. We study two different models. In the first model we assume barotropic fluid with the linear equation of state as the first component of total fluid.

THERMODYNAMIC EXPRESSIONS FOR MELTING OF TWO COMPONENT COPOLYMERS

open access: yesSen'i Gakkaishi, 1973
As the representative theories on melting in copolymers composed of units of type A capable of crystallizing and other units B incapable of crystallizing, two theories proposed by P. J. Flory in 1949 and in 1955 are known well. However, there are not a few experimental results on melting in copolymers that can not be explained enough even with those ...

Thermodynamics properties of the coexisting phases and thermochemical properties of the NaCl component in boiling NaCl solutions

open access: yes, 1976
Preliminary steam tables that give the thermodynamic data for the coexisting liquid and gas and that give the thermochemical data for the NaCl component in the liquid for the system H/sub 2/O--NaCl are given for liquid concentrations between 0 mol NaCl ...

Preparation and Thermal Modification of Disentangled Ultrahigh‐Molecular‐Weight Polyethylene Particles for Powder‐Based Additive Manufacturing

open access: yesAdvanced Engineering Materials, EarlyView.
Ultrahigh‐molecular‐weight polyethylene powders (<≈40 μm) with a bulk density of 260 g L−1 are prepared from a silica supported bisimine pyridine iron catalyst. The nascent product is disentangled and can be thermally densified without loss of its low viscosity.

On Equivalence of Nonequilibrium Thermodynamic and Statistical Entropies

open access: yesEntropy, 2015
We review the concept of nonequilibrium thermodynamic entropy and observables and internal variables as state variables, introduced recently by us, and provide a simple first principle derivation of additive statistical entropy, applicable to all ...
