Temperature, inocula and substrate: contrasting electroactive consortia, diversity and performance in microbial fuel cells [PDF]

open access: yes, 2018
The factors that affect microbial community assembly and its effects on the performance of bioelectrochemical systems are poorly understood. Sixteen microbial fuel cell (MFC) reactors were set up to test the importance of inoculum, temperature and ...

Neutron capture cross section and capture gamma-ray spectra of 138Ba in the keV-neutron energy region

open access: yesEPJ Web of Conferences, 2015
The neutron capture cross sections and the capture γ-ray spectra of 138Ba were measured in the astrophysically important energy region. Measurements were made at neutron energies from 15 to 80 keV.

Interfacial Heat Transfer of Condensation Bubble with Consideration of Bubble Number Distribution in Subcooled Flow Boiling

open access: yesJournal of Thermal Science and Technology, 2013
For predicting the void fraction distribution in subcooled flow boiling, it is necessary to measure the interfacial heat transfer coefficient—which determines the amount of condensation rate of vapor bubble—with high accuracy.
