High-Speed Nanomechanical Property Mapping of Polyetherimide/Zinc Titanate Nanocomposites


Material Science

Determination of mechanical properties of modern nanocomposite materials through conventional macroscale test methods is always challenging and questionable. Nanoparticles interact with polymer molecules at a micron to nanoscale, and hence to precisely determine the properties of these composites, micron level test methods such as nanoindentation need to be utilized. In this work, we have used the nanoindentation techniques combined with a recently developed novel accelerated property mapping (XPM) technique to study the statistical quantification of mechanical properties such as hardness and modulus, and the variance of these properties across the phases of polyetherimide (PEI) nanocomposites reinforced with 5, 10, 15 wt. % of zinc titanate (ZnTiO3) nanoparticles.

Effect of Infrared Radiation on the Hydrogen in Thin Films Double Barriers Based Melt Silicone-Germany

Abstract Possibilities of plasma chemical deposition of α-Si 1-x Ge x :H (x=0÷1) films undoped and doped with PH 3 or B 2 H 6 have been analyzed from the viewpoint of their application in p-i-n structures of solar cell. The optical properties are considered, and the amount of hydrogen contained in those films is determined. The film properties are found to strongly depend on the film composition and the hydrogenation level. The number of hydrogen atoms in the films is varied by changing the gas mixture composition, and IR absorption in α-Si:H and α-G e :H films is measured. The α-Si:H and а-Si 0,88 Ge 1,2 :H films were used to fabricate three-layer solar with an element area of 1,3 sm 2 and an efficiency (η) of 9.5 %.

The Erroneous Banishment of Plastics Authorized by Walter Eevers Since some months, youth is marching in the streets of several cities throughout Europe. They scream for political attention for the fight against climate change. The debates in the press and on social media go into all directions and give attention to technological solutions to fight climate change, the need for personal lifestyle adaptation but also to fights against nuclear power generation, air traffic etc. But in the margin of these protests also plastics and the use of plastics are condemned in many of these communications.
