Implications of automatic photon quenching on compact gamma-ray sources [PDF]

open access: yes, 2011
Aims: We investigate photon quenching in compact non-thermal sources. This involves photon-photon annihilation and lepton synchrotron radiation in a network that can become non-linear.

Fluorescence-based primary productivity estimates are influenced by non-photochemical quenching dynamics in Arctic phytoplankton

open access: yesFrontiers in Microbiology, 2023
Chlorophyll fluorescence-based estimates of primary productivity typically include dark or low-light pre-treatments to relax non-photochemical quenching (NPQ), a process that influences the relationship between PSII photochemistry and fluorescence yields.

An experimental and CFD study of liquid jet injection into a partially baffled mixing vessel: a contribution to process safety by improving the quenching of runaway reactions [PDF]

open access: yes, 2008
Thermal runaway remains a problem in the process industries with poor or inadequate mixing contributing significantly to these incidents. An efficient way to quench such an uncontrolled chemical reaction is via the injection of a liquid jet containing a ...

Study of Tailored Hot Stamping Process on Advanced High-Strength Steels

open access: yesJournal of Manufacturing and Materials Processing, 2022
Ultra-high-strength steels (UHSS) combined with tailor-stamping technologies are increasingly being adopted in automotive body production due to crashworthiness improvements and part weight reduction, which meet safety and energy saving demands. Recently,

Heat transfer analysis of the forced air quenching with non-isothermal and non-uniform oxidation.

open access: yesPLoS ONE, 2021
In this paper, the heat transfer characteristics of the forced air quenching with non-isothermal and non-uniform oxidation are investigated. By introducing the variations of interfacial temperature and oxygen partial pressure, a three-layered non ...

Nonmonotonic energy harvesting efficiency in biased exciton chains [PDF]

open access: yes, 2007
We theoretically study the efficiency of energy harvesting in linear exciton chains with an energy bias, where the initial excitation is taking place at the high-energy end of the chain and the energy is harvested (trapped) at the other end.

Medium-induced cascade in expanding media

open access: yesJournal of High Energy Physics, 2020
Detailed insight into the interplay between parton energy loss and the way deconfined medium created in heavy-ion collisions expands is of great importance for improving the understanding of the jet quenching phenomenon. In this paper we study the impact

Experimental and Numerical Process Design for Press Partitioning of the New Q&P Steel 37SiB6

open access: yesMetals, 2023
Quenching and partitioning (Q&P) heat treatments of low-alloy steels with exceptional property combinations are particularly promising. In this study, we characterize for the first time a new low-alloy steel to be processed using Q&P heat treatments.

Energy loss, equilibration, and thermodynamics of a baryon rich strongly coupled quark-gluon plasma [PDF]

open access: yes, 2016
Lattice data for the QCD equation of state and the baryon susceptibility near the crossover phase transition (at zero baryon density) are used to determine the input parameters of a 5-dimensional Einstein-Maxwell-Dilaton holographic model that provides a
