Investigating the Efficiency of Explosion Chemistry as a Source of Complex Organic Molecules in TMC-1 [PDF]

open access: yes, 2019
Many species of complex organic molecules (COMs) have been observed in several astrophysical environments but it is not clear how they are produced, particularly in cold, quiescent regions.

Ultrafaint Dwarfs - Star Formation and Chemical Evolution in the Smallest Galaxies [PDF]

open access: yes, 2014
In earlier work we showed that a dark matter halo with a virial mass of $10^7$ M$_\odot$ can retain a large percentage of its baryons in the face of the pre-ionization phase and supernova explosion from a 25$M_\odot$ star.

The origin of the high velocity circumstellar gas around SN 1998S [PDF]

open access: yes, 2001
Modelling of high resolution Balmer line profiles in the early-time spectra of SN 1998S shows that the inferred fast (roughly 400 km/s) circumstellar (CS) gas on days 23 and 42 post-explosion is confined to a narrow, negative velocity gradient shell just

Instabilities and soot formation in high-pressure, rich, iso-octane-air explosion flames - 1. Dynamical structure [PDF]

open access: yes, 2007
Simultaneous OH planar laser-induced fluorescence (PLIF) and Rayleigh scattering measurements have been performed on 2-bar rich iso-octane–air explosion flames obtained in the optically accessible Leeds combustion bomb.

Influence of Gas from Long-Flame Coal Spontaneous Combustion on Gas Explosion Limit

open access: yesInternational Journal of Chemical Engineering, 2023
To investigate the impact of multiple combustible gases produced by long-flame coal spontaneous combustion on the gas explosion limit and to guide the reoperation of the coal mine goaf and fire area, the influence of gas generated by coal spontaneous ...

Continuous Gas explosions in NigeriaContinuous Gas explosions in Nigeria

open access: yes, 2018
This study examined “gas explosions in Nigeria: the causes and management’’. The study depended on the secondary source of information. A gas explosion has become a very tragic accident in Nigeria that when it happens, many families morn. For instance, the recent explosion in Lafia, the Nasarawa State capital (10th September 2018) has left over fifty ...

Simulation of gas explosions [PDF]

open access: yesModeling, Identification and Control: A Norwegian Research Bulletin, 1989
Gas explosion hazard assessments in flammable gas handling operations both offshore and onshore are crucial in order to obtain an acceptable level of safety. In order to perform such assessments good predictive tools are needed, which take account of the relevant parameters, such as geometrical design variables and gas cloud type and distribution.

Silicon clusters produced by femtosecond laser ablation: Non-thermal emission and gas-phase condensation

open access: yes, 2004
Neutral silicon clusters Si_n (up to n = 7) and their cations Si_n+ (up to n = 10) have been produced by femtosecond laser ablation of bulk silicon in vacuum and investigated using time-of-flight mass spectrometry.
