The Influence of Mixing Methods of Epoxy Composition ...

2021-1-15 · The best properties are obtained by introducing the smallest possible fillers, preferably with particle sizes measured on a nanometric scale [9,10]. It should be noted that smaller particles (e.g., nano-scale) disperse better in the resin matrix, hence a more homogeneous structure of the resulting compositions is obtained.

Microscopy and Microanalysis: Volume 21

The combined use of microscopy and X-ray spectroscopy analyses allowed us to identify the vestigial materials used for making the parchments, including products such as salt (NaCl), lime (CaO), pumice stone (SiO 2 +Al 2 O 3), and chalk (CaCO 3). Chalk was employed as a whitening agent to give the parchment its final color and opacity.

A wurtzite structure, in which Mn2+ replaces Zn2+, was obtained with a nanometric character. The photoluminescence of samples showed the characteristic (Mn2+T1)-T-4-(6)A(1) emission that was highly dependent on the doping level. The maximum luminescence efficiency through the ZnS excitation was found for a doping value of 1 mol%.

2018-4-1 · Lithography and lift-off of the catalyst is the established way to pattern forests of carbon nanotubes (CNTs). We demonstrate an alternative technique where we pattern a thin film reservoir residing below the Al 2 O 3 underlayer to partially or fully deactivate the iron catalyst on the surface, thus leading to short CNTs or no CNTs. High-resolution imaging suggests that …
