Shahmohammadi, M.S. (author), Parker, L.A. (author), Henke, S. (author), Urbanus, J.H. (author)Microplastics are a growing environmental and toxicological concern, having been found in the remotest locations of the earth and within multiple organs of the human body. However, the scale of the problem is not yet fully known as the smallest micro- and nanoplastics (MNPs) cannot accurately be measured due to limitations in measurement and...article 2022

Roch, T. (author), Šimurka, L. (author), Ow-Yang, C.W. (author), Sezen, M. (author), Satrapinskyy, L. (author), Turutoğlu, T. (author)Magnetron sputtering is widely used for deposition of silicon oxynitride (SiOxNy) coatings on glass in large-area applications. Since repeated deposition simulates the factory-scale in-line processing, amorphous aluminum-doped SiOxNy layers with thickness of about 250 nm were deposited by reactive pulsed DC sputtering in a multi-pass process...article 2019

Yang, G. (author), Guo, P. (author), Procel, P. (author), Weber, A.W. (author), Isabella, O. (author)The poly-Si carrier-selective passivating contacts (CSPCs) parasitically absorb a substantial amount of light, especially in the form of free carrier absorption. To minimize these losses, we developed CSPCs based on oxygen-alloyed poly-Si (poly-SiOx) and deployed them in c-Si solar cells. Transmission electron microscopy analysis indicates the...article 2018

(author)To date, conventional thermal atomic layer deposition (ALD) has been the method of choice to deposit high-quality Pt thin films grown typically from (MeCp)PtMe3 vapor and O2 gas at 300 °C. Plasma-assisted ALD of Pt using O2 plasma can offer several advantages over thermal ALD, such as faster nucleation and deposition at lower temperatures. In...article 2017
