Nanotechnology in cosmetics

Prof. Beata Kaczmarek, Szczepańska Nicolaus

Copernicus University, Poland

Prof. Beata discussed the regulations of nanoparticles used in the cosmetic industry. She further shed light
on the opportunities and challenges of their application in cosmetics. Nanomaterials in cosmetics could

have various functions (e.g., UVA and UVB filters in sunscreens, nano-preservatives). At last, she gave a
brief explanation about the safety of nano cosmetics. This talk mainly focused on biomaterials and
cosmetics, especially including natural compounds.

X-ray: Non-destructive testing of materials and

composites

Dr. Anja Waske, BAM Federal Institute for Materials
Research and Testing, Berlin, Germany

She brought up an interesting topic about how X-ray tomography investigations can contribute to
structure elucidation in composites and solid samples. These X-rays are non-destructive to characterize
cracks, pores, and other defects. Their influence on the functional properties in three-dimensional analysis

can improve the material's life cycle was explained. If one can combine microtomography with other
methods of magnetic material characterization, one can determine unique statements about the structure
and the functional properties of that material.

Spark Plasma Texturing: A technology development

for lead-free piezoelectrics

Prof. Paula M. Vilarinho, University of Aveiro, Pourtgal

Prof. Vilarinho described the interplay between material

structure, microstructure, electrical conductivity, and non-linear dielectric properties for Spark plasma
Texturing (SPT) (K1-xNax)NbO3 (KNN) and the key idea to inducing the electrical properties. Nowadays,

the need for sensors and actuators are rising. To meet the above application professor shared the vision
about the functional oxides, including piezoelectric ceramics used in compact electronic equipment and
tools. Furthermore, she explained how the KNN system replaces the lead-based piezoelectrics and the
work that exploited the one derivative method of spark plasma sintering. Moreover, she concluded with

significant improvement in undoped KNN ceramics processed, SPT in inducing the dielectric and
piezoelectric performances. This talk addressed mainly the sintering of undoped lead-free piezoelectric.
