Modern hybrid pigments and second-generation dry-pigment preparations have a performance potential that cannot be achieved with basic dry-blending techniques. Due to their properties, well-known inorganic pigments, such as complex inorganic color (CIC), pigments are suitable for a range of high-performance applications. They are easy to disperse and are therefore a sustainable factor in the manufacture of coatings. They give coatings opacity, chemical resistance and excellent outdoor durability. The idea behind the hybrid pigment technology is the combination of a highly resistant and easy-to-process micronized-pigment core particle with pre-dispersed high performance organic pigments. Another positive effect of the hybrid-pigment concept is improved hiding power and the degree of improvement depends on the shade and formulation that can reach a high level. A new process has recently come into the market to simplify the coloring of products in the paint and plastic industry.

Pigments are basically used to impart color. But the reflection of Near Infrared Radiation (NIR) is a requirement of modern pigments that gains particular importance for a multitude of uses. This paper reports about smart ways to formulate with this class of pigments. The main objective in this context is the enhancement of coloristic and NIR-reflective properties in typical plastics applications.

GaN nanotubes with coaxial InGaN quantum wells were analyzed by scanning transmission electron microscopy in order to determine their structural properties as well as the indium distribution across the InGaN quantum wells. For the latter, two process steps are necessary. First, a technique to prepare cross-sectional slices out of the nanotubes has been developed. Second, an existing scanning transmission electron microscopy analysis technique has been extended with respect to the special crystallographic orientation of this type of specimen. In particular, the shape of the nanotubes, their defect structure, and the incorporation of indium on different facets were investigated. The quantum wells preferentially grow on m-planes of the dodecagonally shaped nanotubes and on semipolar top facets while no significant indium signal was found on a-planes. An averaged indium concentration of 6% to 7% was found by scanning transmission electron microscopy analysis and could be confirmed by cathodoluminescence measurements. © 2016 Author(s).
