Asymmetric transformation of achiral gold nanoclusters with negative nonlinear dependence between chiroptical activity and enantiomeric excess

open access: yesNature Communications, 2023
The investigation of chirality at the nanoscale is important to bridge the gap between molecular and macroscopic chirality. Atomically precise metal nanoclusters provide an ideal platform for this research, while their enantiopure preparation poses a ...

A virtual structure for hybrid networks [PDF]

open access: yes2004 IEEE Wireless Communications and Networking Conference (IEEE Cat. No.04TH8733), 2004
Hybrid networks are heterogeneous networks merging both wireless and ad hoc nodes and where the interconnection to the IP world is an important topic through gateways called AP (access point). Indeed, each node can be contacted and can contact another node in the Internet. To reach that, architectures that support mobility management are studied.

THE INNER STRUCTURE OF HYBRID STARS [PDF]

open access: yes, 2006
Hybrid stars with extremely high central energy density in their core are natural laboratories to investigate the appearance and the properties of compactified extra dimensions with small compactification radius -- if these extra dimensions exist at all. We introduce the necessary formalism to describe quantitatively these objects and the properties of
