Impact of washing parameters on bacterial filtration efficiency and breathability of community and medical facemasks

open access: yesScientific Reports, 2022
Can medical face masks be replaced by reusable community face masks with similar performance? The influence of the number of wash cycles, the wash temperature and the use of detergent was evaluated on the performance of one medical face masks (MFM) and ...

Stable carbon isotope fractionation in chlorinated ethene degradation by bacteria expressing three toluene oxygenases

open access: yesFrontiers in Microbiology, 2012
One difficulty in using bioremediation at a contaminated site is demonstrating that biodegradation is actually occurring in situ. The stable isotope composition of contaminants may help with this, since they can serve as an indicator of biological ...

Filtration efficiency of medical and community face masks using viral and bacterial bioaerosols

open access: yesScientific Reports, 2023
Face masks are often recommended in community settings to prevent the airborne transmission of respiratory viruses or bacteria. Our first objective was to develop an experimental bench to assess the viral filtration efficiency (VFE) of a mask with a ...

Chemical Stress Relaxation of cis-1, 4-polybutadiene

open access: yesThe Journal of the Society of Chemical Industry, Japan, 1966
Polybutadiene is considered to be most promising elastomers in synthetic rubber industry as the result of remarkable improvement made on this material in recent years so that it contains now nearly all cis-1, 4 in its structure. The chemorheological study of this material is in this way becoming a very interesting subject.For the measurement of stress ...
