Autor: Nilanjon Naskar, Martin F. Schneidereit, Florian Huber, Sabyasachi Chakrabortty, Lothar Veith, Markus Mezger, Lutz Kirste, Theo Fuchs, Thomas Diemant, Tanja Weil, R. Jürgen Behm, Klaus Thonke, Ferdinand Scholz

Publikováno v: Sensors, Vol 20, Iss 15, p 4179 (2020)

The development of sensitive biosensors, such as gallium nitride (GaN)-based quantum wells, transistors, etc., often makes it necessary to functionalize GaN surfaces with small molecules or even biomolecules, such as proteins. As a first step in surf

Visible light induced RAFT for asymmetric functionalization of silica mesopores

Autor: Claire, Förster, Lothar, Veith, Annette, Andrieu-Brunsen

Publikováno v: RSC advances. 12(42)

One key feature for bioinspired transport design through nanoscale pores is nanolocal, asymmetric as well as multifunctional nanopore functionalization. Here, we use a visible-light induced, controlled photo electron/energy transfer-reversible additi

Tuning the Charge of Sliding Water Drops

Autor: William S. Y. Wong, Pravash Bista, Xiaomei Li, Lothar Veith, Azadeh Sharifi-Aghili, Stefan A. L. Weber, Hans-Jürgen Butt

Publikováno v: Langmuir

When a water drop slides over a hydrophobic surface, it usually acquires a positive charge and deposits the negative countercharge on the surface. Although the electrification of solid surfaces induced after contact with a liquid is intensively studi

Chemical Strain Engineering of MAPbI3 Perovskite Films

Autor: Yenal Yalcinkaya, Ilka M. Hermes, Tobias Seewald, Katrin Amann‐Winkel, Lothar Veith, Lukas Schmidt‐Mende, Stefan A.L. Weber

Publikováno v: Advanced Energy Materials

This study introduces a new chemical method for controlling the strain in methylammonium lead iodide (MAPbI3) perovskite crystals by varying the ratio of Pb(Ac)2 and PbCl2 in the precursor solution. To observe the effect on crystal strain, a combinat

Distribution of Paramagnetic Fe2O3/SiO2–Core/Shell Nanoparticles in the Rat Lung Studied by Time-of-Flight Secondary Ion Mass Spectrometry: No Indication for Rapid Lipid Adsorption

Autor: Lothar Veith, Antje Vennemann, Daniel Breitenstein, Carsten Engelhard, Birgit Hagenhoff, Martin Wiemann

Publikováno v: Nanomaterials, Vol 8, Iss 8, p 571 (2018)

Amorphous silica nanoparticles comprise a class of widely used industrial nanomaterials, which may elicit acute inflammation in the lung. These materials have a large specific surface to which components of the pulmonary micro-milieu can bind. To con

Detection of ZrO2 Nanoparticles in Lung Tissue Sections by Time-of-Flight Secondary Ion Mass Spectrometry and Ion Beam Microscopy

Autor: Lothar Veith, Julia Böttner, Antje Vennemann, Daniel Breitenstein, Carsten Engelhard, Jan Meijer, Irina Estrela-Lopis, Martin Wiemann, Birgit Hagenhoff

Publikováno v: Nanomaterials, Vol 8, Iss 1, p 44 (2018)

The increasing use of nanoparticles (NP) in commercial products requires elaborated techniques to detect NP in the tissue of exposed organisms. However, due to the low amount of material, the detection and exact localization of NP within tissue secti
