Colorimetric determination of formaldehyde in air using a hanging drop of chromotropic acid
(Royal Soc Chemistry, 2000-12-01)
A simple and sensitive method to determine parts per billion (ppb) of atmospheric formaldehyde in situ, using chromotropic acid, is described. A colorimetric sensor, coupled to a droplet of 15.5 muL chromotropic acid, was ...

The Final Months of Massive Star Evolution from the Circumstellar Environment around SN Ic 2020oi
(IOP Publishing, 2021-09)
We present the results of Atacama Large Millimeter/submillimeter Array (ALMA) band 3 observations of the nearby type Ic supernova (SN) 2020oi. Under the standard assumptions on the SN-circumstellar medium (CSM) interaction ...
