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….

Selective anodes for seawater splitting via functionalization of manganese oxides by a plasma-assisted process
