Formaldehyde sensing by Co3O4 hollow spheres at room temperature [PDF]
arXiv, 2020 Formaldehyde is a ubiquitous and high toxicity gas. It is an essential task to efficient detect owing to their toxicity and diffusion. In this work, we studied on the detection of trace amount of formaldehyde based on hollow Co3O4 nanostructure. It is found that Co3O4 hollow spheres with different structures shows distinct sensing performance towards ...

Spectroscopy of formaldehyde in the 30140-30790cm^-1 range [PDF]
J. Mol. Spec. 252, 25 (2008), 2008 Room-temperature absorption spectroscopy of formaldehyde has been performed in the 30140-30790cm^-1 range. Using tunable ultraviolet continuous-wave laser light, individual rotational lines are well resolved in the Doppler-broadened spectrum. Making use of genetic algorithms, the main features of the spectrum are reproduced.

Evaluation of two eco-friendly neutralizers for a spectrum of tissue fixatives for biomedical applications. [PDF]
, 2018 Formaldehyde is a widely used aldehyde in biomedical applications, including tissue fixation. It is this same fixative property that can result in toxicity if aldehydes are improperly discarded.

The distribution of deuterated formaldehyde within Orion-KL [PDF]
, 2015 We report the first high angular resolution imaging (3.4\arcsec $\times$ 3.0\arcsec) of deuterated formaldehyde (HDCO) toward Orion--KL, carried out with the Submillimeter Array (SMA). We find that the spatial distribution of the formaldehyde emission systematically differs from that of methanol: while methanol is found towards the inner part of the ...

Detection of protonated formaldehyde in the prestellar core L1689B [PDF]
A&A 588, L8 (2016), 2016 Complex organic molecules (COMs) are detected in many regions of the interstellar medium, including prestellar cores. However, their formation mechanisms in cold (~10 K) cores remain to this date poorly understood. The formyl radical HCO is an important candidate precursor for several O-bearing terrestrial COMs in cores, as an abundant building block ...

Microencapsulation of Butyl Stearate as Phase Change Material by Melamine Formaldehyde Shell for Thermal Energy Storage [PDF]
Journal of Chemical and Petroleum Engineering, 2017 Butyl stearate as a phase change material was microencapsulated within melamine-formaldehyde resin using emulsion polymerization. Morphology and thermal specification of produced microcapsules were studied by Fourier transform infrared spectroscopy, FT ...

Critical role of formaldehyde during methanol conversion to hydrocarbons
Nature Communications, 2019 Formaldehyde is an important intermediate product in the catalytic conversion of methanol to olefins (MTO). Here we show that formaldehyde is present during MTO with an average concentration of ~0.2 C% across the ZSM-5 catalyst bed up to a MeOH ...

Studies on the formation of formaldehyde during 2-ethylhexyl 4-(dimethylamino)benzoate demethylation in the presence of reactive oxygen and chlorine species [PDF]
Studzi\'nski, W., Gackowska, A., Przyby{\l}ek, M. et al. Environ
Sci Pollut Res (2017) 24: 8049. https://doi.org/10.1007/s11356-017-8477-8, 2018 In order to protect the skin from UV radiation, personal care products (PCPS) often contain chemical UV-filters. These compounds can enter the environment causing serious consequences on the water ecosystems. The aim of this study was to examine, the effect of different factors, such as UV light, the presence of NaOCl and H2O2 on the formaldehyde ...
