Design and fabrication of an electrostatic precipitator for infrared spectroscopy

Infrared (IR) spectroscopy is a direct measurement technique for chemical characterization of aerosols that can be applied without solvent extraction thermal treatment a priori. This technique has been used for chemical speciation, source apportionme

Fragment ion-functional group relationships in organic aerosols using aerosol mass spectrometry and mid-infrared spectroscopy

Autor: Nikunj Dudani, Amelie Bertrand, Imad El Haddad, Satoshi Takahama, André S. H. Prévôt, Amir Yazdani, Ann M. Dillner

Aerosol mass spectrometry (AMS) and mid-infrared spectroscopy (MIR) are two analytical methods for characterizing the chemical composition of organic matter (OM). While AMS provides high-temporal-resolution bulk measurements, the extensive fragmentat

Characterization of primary and aged wood burning and coal combustion organic aerosols in environmental chamber and its implications for atmospheric aerosols

Autor: Amir Yazdani, Nikunj Dudani, Satoshi Takahama, Amelie Bertrand, André S. H. Prévôt, Imad El Haddad, Ann M. Dillner

Particulate matter (PM) affects visibility, climate, and public health. Organic matter (OM), a uniquely complex portion of PM, can make up more than half of total atmospheric fine PM. We investigated the effect of aging on secondary organic aerosol (

Organic functional group composition of particulate matter from fresh and aged wood burning and coal combustion

Autor: Amelie Bertrand, Imad El Haddad, Amir Yazdani, André S. H. Prévôt, Satoshi Takahama, Ann M. Dillner, Nikunj Dudani

Particulate matter (PM) affects visibility and climate through light scattering, direct and indirect radiative forcing, and affecting cloud formation [1]. In addition, exposure to ambient fine PM is estimated to have caused 8.9 million deaths worldwi

Aberration-corrected cryoimmersion light microscopy

Autor: Christian Boeker, Nikunj Dudani, Thomas P. Burg, Till Stephan, Yara X. Mejia, Stefan Jakobs, R. Faoro, Margherita Bassu

Publikováno v: Proceedings of the National Academy of Sciences of the United States of America

Significance Cryofluorescence imaging is of great interest in biological microscopy because vitrified samples (i.e., frozen without ice crystallization) are free from fixation artifacts, are highly photostable, and allow direct correlation with elect

Method and apparatus for quantitative measurement of aerosol composition using controlled collection of airborne particles

Autor: Nikunj Dudani, Satoshi Takahama

It is important to characterize the composition of aerosol particles in air, which causes adverse health effects and millions of deaths each year. Aerosol, or particulate matter (PM), is difficult to characterize because of its wide range of particle
