High-purity hydrogen generated from a single device

(PhysOrg.com) -- There are many ways to generate hydrogen, such as water electrolysis and steam reforming of gas, but the hydrogen produced by these methods tends to be combined with other byproduct and residual gases. For ...

Deuterated formaldehyde detected in protostar HH 212

Using the Atacama Large Millimeter Array (ALMA) in Chile, a team of researchers has detected the emission of deuterated formaldehyde (HDCO) from the hot inner region of the protostar HH 212. The finding, reported January ...

Researchers develop “net” nanodetector

Bin Ding and his team of researchers at Donghua University, Shanghai, China, have developed a new method of testing for formaldehyde using an electro-spinning netting technique. The process, described in their paper published ...

A known environmental hazard can change the epigenetics of cells

Epigenetics, the chemical mechanisms that control the activity of genes, allows our cells, tissues and organs to adapt to the changing circumstances of the environment around us. This advantage can become a drawback, though, ...

Formaldehyde is an organic compound with the formula CH2O. It is the simplest aldehyde, hence its systematic name methanal.

Formaldehyde is a colorless gas with a characteristic pungent odor. It is an important precursor to many other chemical compounds, especially for polymers. In 2005, annual world production of formaldehyde was estimated to be 23 million tonnes (50 billion pounds). Commercial solutions of formaldehyde in water, commonly called formalin, were formerly used as disinfectants and for preservation of biological specimens.

In view of its widespread use, toxicity and volatility, exposure to formaldehyde is a significant consideration for human health. On 10 June 2011, the US National Toxicology Program has described formaldehyde as "known to be a human carcinogen".
