Quenching and partitioning - a new steel heat treatment concept [PDF]

open access: yes, 2011
Steel continues to be one of the primary materials in use today, however, even after 200 years of published research, innovative methods are being discovered and exploited to produce steel with enhanced properties.

QUENCHING OF THE DEUTERON IN FLIGHT [PDF]

open access: yesInternational Journal of Modern Physics E, 2007
We investigate the Lorentz contraction of a deuteron in flight. Starting from the Blankenbecler-Sugar projection of the Bethe-Salpeter equation to a 3-dimensional quasi potential equation, we apply it for the deuteron bound in an harmonic oscillator potential (for an analytical result) or by the Bonn NN potential for a more realistic estimate. We find

Applications of fluorescence spectroscopy in protein conformational changes and intermolecular contacts

open access: yesBBA Advances, 2023
Emission fluorescence is one of the most versatile and powerful biophysical techniques used in several scientific subjects. It is extensively applied in the studies of proteins, their conformations, and intermolecular contacts, such as in protein-ligand ...

Quenching-driven equatorial depletion and limb asymmetries in hot Jupiter atmospheres: WASP-96b example [PDF]

open access: yes
Transport-induced quenching in hot Jupiter atmospheres is a process that determines the boundary between the part of the atmosphere at chemical equilibrium and the part of the atmosphere at thermochemical (but not photothermochemical) disequilibrium. The

The Effect of Heat Treatment on the Microstructure and Mechanical Properties of Cu-Al-Mn Shape Memory Alloy [PDF]

open access: yesKemija u Industriji, 2018
The 8-mm diameter bars of Cu-Al-Mn shape memory alloys were produced by continuous casting technique. The samples were characterised using optical microscopy and scanning electron microscopy along with EDX analysis.

Modelling fluorescence quenching in systems with restricted diffusion: applications to oligonucleotides and polypeptides [PDF]

open access: yes, 2004
The objectives of the present thesis are 1) to systematically develop a series of models and theoretical expressions for the diffusion-controlled reaction, which can be used to analyze the time-resolved fluorescence data in systems where the diffusion is

THE QUENCHING TIMESCALE AND QUENCHING RATE OF GALAXIES

open access: yesThe Astrophysical Journal, 2016
ABSTRACT The average star formation rate (SFR) in galaxies has been declining since the redshift of 2. A fraction of galaxies quench and become quiescent. We constrain two key properties of the quenching process: the quenching timescale and the quenching rate among galaxies.

THE USE OF CARBON, HIGH-CHROMIUM STEELS FOR LINERS OF MUD PUMPS AND DRILLING RIGS

open access: yesИзвестия высших учебных заведений: Нефть и газ, 2017
The paper shows that high temperature heating (from 1 100 to 1 170 0C) for the subsequent quenching of high-chromium steels of a martensitic-carbide class 95X18 and X12MFL provides structure to the metal base, which consist of high-carbon containing ...

Microstructure and Mechanical Behavior of Cu-Al-Ni-B Alloys with Thermoelastic Martensitic Transformation

open access: yesMetals, 2023
For the first time, using optical, scanning, and transmission electron microscopy and X-ray phase analysis in combination with measurements of tensile mechanical properties, we obtained data on the structural features of the polycrystalline shape-memory ...
