Investigation of Anti-Relaxation Coatings for Alkali-Metal Vapor Cells Using Surface Science Techniques

, 2010
Many technologies based on cells containing alkali-metal atomic vapor benefit from the use of anti-relaxation surface coatings in order to preserve atomic spin polarization.

Towards atomic resolution in sodium titanate nanotubes using near-edge X-ray-absorption fine-structure spectromicroscopy combined with multichannel multiple-scattering calculations

Beilstein Journal of Nanotechnology, 2012
Recent advances in near-edge X-ray-absorption fine-structure spectroscopy coupled with transmission X-ray microscopy (NEXAFS–TXM) allow large-area mapping investigations of individual nano-objects with spectral resolution up to E/ΔE = 104 and spatial ...

Molybdenum Doping Activates Lattice Oxygen in Ruthenium Oxide for Efficient Acidic Water Oxidation

Small Structures, Volume 7, Issue 2, February 2026.
Mo dopants with valence of higher than +4 may create cation vacancies, increase the valence of Ru and O, and enhance the covalency of Ru‐O in RuO2, which leads to the activation of lattice oxygen and LOM reaction pathway and improves the electrocatalytic performance of RuO2 in acidic medium.

Electronic structure of single-crystalline Mg$_x$Al$_{1-x}$B$_2$ probed by x-ray diffraction multipole refinements and polarization-dependent x-ray absorption spectroscopy

, 2012
X-ray diffraction multipole refinements of single-crystalline Mg$_x$Al$_{1-x}$B$_2$ and polarization-dependent near-edge x-ray absorption fine structure at the B 1$s$ edge reveal a strongly anisotropic electronic structure.

NEXAFS imaging to characterize the physio-chemical composition of cuticle from African Flower Scarab Eudicella gralli

Nature Communications, 2019
Biology serves as inspiration in materials development; this requires improved understanding of the surface chemistry responsible for processes which are being mimicked.

Suppression of spin-state transition in epitaxially strained LaCoO_{3}

, 2008
Epitaxial thin films of LaCoO_{3} (E-LCO) exhibit ferromagnetic order with a transition temperature T_c = 85 K, while polycrystalline thin LaCoO_{3} films (P-LCO) remain paramagnetic.

Core-level spectra and molecular deformation in adsorption: V-shaped pentacene on Al(001)

Beilstein Journal of Nanotechnology, 2015
By first-principle simulations we study the effects of molecular deformation on the electronic and spectroscopic properties as it occurs for pentacene adsorbed on the most stable site of Al(001).

Quasi-freestanding and single-atom thick layer of hexagonal boron nitride as a substrate for graphene synthesis

, 2010
We demonstrate that freeing a single-atom thick layer of hexagonal boron nitride (hbn) from tight chemical bonding to a Ni(111) thin film grown on a W(110) substrate can be achieved by intercalation of Au atoms into the interface.
