About Maria Nila
Formaldehyde is the simplest aldehyde made of hydrogen, carbon and oxygen with the formula CH2O. Formaldehyde is one of a large family of chemicals known as volatile organic compounds which evaporates and become gaseous at room temperature. Formaldehyde is a reactive molecule and first in the series of aliphatic aldehydes. Formaldehyde, being the simplest aldehyde has a very simple structure. Its molecule consists of a carbon atom from which two hydrogen atom is attached by a single bond and a oxygen atom which is bonded to the carbon atom by a double bond.
The formaldehyde line emission structure of IC 860 is presented in Fig. 2 as a zeroth-moment colour map overlaid on the radio continuum map. The moment map incorporates line emission features above a threshold of 0.8 mJy beam −1, while the rms in the line channel maps (away from the location of the source) is 0.31 mJy beam −1. The formaldehyde line emission structure of IC860 is presentedinFigure2asazeroth-momentcolourmapover-laidontheradiocontinuummap.Themomentmapincor- Symbol which looks like a small house Solid circle with an upward pointer in it. Jump to content α-, β-, γ- and δ-MnO2 catalysts were prepared by a hydrothermal method and tested for the catalytic oxidation of formaldehyde (HCHO) at low temperature. Dramatic differences in activities among the MnO2 catalysts with different crystal structures were observed. A copolymer containing melamine, formaldehyde, and sodium bisulfite produces a foam with sound-absorbing and flame-retardant properties. The foam has a notably hard microbubble structure, which gives it an abrasive quality that has been utilized in the development of cleaning products.
