Applied Physics Reviews 8, 011408 (2021)

Abstract:
Recent developments in attosecond technology led to table-top x-ray spectroscopy in the soft x-ray range, thus uniting the element- and state-specificity of core-level x-ray absorption spectroscopy with the time resolution to follow electronic dynamics…

Nature Chemistry volume 13pages420–427 (2021)

Abstract:
Molecular Russian dolls (matryoshkas) have proven useful for testing the limits of preparative supramolecular chemistry but applications of these architectures to problems in other fields are elusive. Here we report a three-shell…

Author: Ivan SpajićEhsan RahimiMaria LekkaRuben OffoiachLorenzo Fedrizzi and Ingrid Milošev

Journal of The Electrochemical SocietyVolume 168Number 7

Abstract:
Thin films of alumina and hafnia were prepared by atomic layer deposition, with the aim of investigating the use of such films in biomedical applications. Films were deposited on commercially pure titanium and on medical stainless steel…

Gigahertz Frame Rate Imaging of Charge-Injection Dynamics in a Molecular Light Source

Gigahertz Frame Rate Imaging of Charge-Injection Dynamics in a Molecular Light Source

Author: Anna RosławskaPablo MerinoChristopher C. LeonAbhishek GrewalMarkus EtzkornKlaus Kuhnke, and Klaus Kern

Nano Lett. 2021, 21, 11, 4577–4583

Abstract:
Light sources on the scale of single molecules can be addressed and characterized at their proper sub-nanometer scale by scanning tunneling microscopy-induced luminescence (STML). Such a source can be driven by defined short charge…

1D charge density wave in the hidden order state of URu2Si2

1D charge density wave in the hidden order state of URu2Si2

Author: Edwin Herrera, Víctor Barrena, Isabel Guillamón, José Augusto Galvis, William J. Herrera, José Castilla, Dai Aoki, Jacques Flouquet & Hermann Suderow

Communications Physics. volume 4, Article number: 98 (2021

Abstract:
Single crystals of URu2Si2 show below 17.5 K a transition into an ordered state with a significantly reduced entropy. The low temperature phase is called the hidden order (HO) state, because its microscopic origin is still unknown—there are no charge….

Applied Catalysis B: Environmental. Volume 284, 5 May 2021

Abstract:
The electrolysis of seawater, a significantly more abundant natural reservoir than freshwater, stands as a promising alternative for sustainable hydrogen production, provided that the competitive chloride electrooxidation is minimized…

Particle and rain erosion mechanisms on Ti/TiN multilayer PVD coatings for carbon fibre reinforced polymer substrates protection

Particle and rain erosion mechanisms on Ti/TiN multilayer PVD coatings for carbon fibre reinforced polymer substrates protection

Author: Borja Coto, Per Hallander, Lucía Mendizabal, Francesco Pagano, Hans Kling, Rocío Ortiz, Javier Barriga, Linnéa Selegård

Wear. Volumes 466–467, 15 February 2021

Abstract:
PVD coatings have been studied as candidates for erosion protection of carbon fibre reinforced polymers. Thus, multilayer Ti/TiN coating stacks with different thicknesses ranging from 1.5 to 11 μm have been deposited by pulsed…

Vibrational Frequencies of Cerium-Oxide-Bound CO: A Challenge for Conventional DFT Methods

Vibrational Frequencies of Cerium-Oxide-Bound CO: A Challenge for Conventional DFT Methods

Author: Pablo G. Lustemberg, Philipp N. Plessow, Yuemin Wang, Chengwu Yang, Alexei Nefedov, Felix Studt, Christof Wöll, and M. Verónica Ganduglia-Pirovano

Phys. Rev. Lett. 125, 256101 – Published 17 December 2020

Abstract:
In ceria-based catalysis, the shape of the catalyst particle, which determines the exposed crystal facets, profoundly affects its reactivity. The vibrational frequency of adsorbed carbon monoxide (CO) can be used as a sensitive probe…
