Three dimensional (3D) characterization of structural defects in nanoparticles by transmission electron microscopy is far from straightforward. We propose the use of a dose-efficient approach, so-called multimode tomography, during which tilt series of low and high angle annular dark field

The use of a palladium (Pd) catalyst has been proposed to promote combustion of tobacco, thereby reducing concentrations of certain toxic components of smoke, including polyaromatic hydrocarbons (PAHs). In the present work, toxicological comparisons were made using experimental cigarettes containing

For patch testing, replacement of the commonly used palladium dichloride (PdCl2) by sodium tetrachloropalladate (Na2[PdCl4]) was recently demonstrated to improve test accuracy and show a significant correlation with nickel (Ni), supporting the concept of cross-reactivity between Pd and Ni. A
