Highly Luminous Scintillating Nanocomposites Enable Ultrafast Time Coincidence Resolution for γ‐rays Detection with Heterostructured Multilayer Scintillators

open access: yesAdvanced Functional Materials, EarlyView.
A scintillating polymeric composites loaded with hafnia nanoparticles is engineered to obtain a highly luminous material, thus achieving a 400% improvement of the scintillation yield under soft X‐rays. The nanocomposite is employed to realize a multilayer heterostructured prototype scintillator than enable for ultrafast time coincidence resolution in ...

Post-quantum Cryptography: Code-Based Signatures [PDF]

open access: yes, 2010
This survey provides a comparative overview of code-based signature schemes with respect to security and performance. Furthermore, we explicitly describe serveral code-based signature schemes with additional properties such as identity-based, threshold ring and blind signatures.

Exploring Electronic States and Ultrafast Electron Dynamics in AlInP Window Layers: The Role of Surface Reconstruction

open access: yesAdvanced Functional Materials, EarlyView.
This study examines the surface characteristics of AlInP (001), crucial for advanced solar cells and photoelectrochemical devices. Using theoretical modeling and experiments, it identifies how phosphorus‐rich and indium‐rich surfaces create mid‐gap states that pin the Fermi level and influence ultrafast electron dynamics.

Rational Design of a Facially Coordinating P,N,N Ligand for Manganese‐Catalysed Enantioselective Hydrogenation of Cyclic Ketones

open access: yesAngewandte Chemie International Edition, Volume 62, Issue 3, January 16, 2023., 2023
A Mn catalyst has been rationally redesigned to repel sp3hybridised substituents while attracting sp2 substituents, and hence enable enantioselective hydrogenation of cyclic ketones. DFT calculations enable a robust prediction of the level of enantiocontrol across a range of substrates.
