New analysis method of the halo phenomenon in finite many-fermion systems. First applications to medium-mass atomic nuclei

open access: yes, 2009
A new analysis method to investigate halos in finite many-fermion systems is designed, as existing characterization methods are proven to be incomplete/inaccurate. A decomposition of the internal wave-function of the {$N$-body} system in terms of overlap

Nuclear Spin‐Free 70Ge/28Si70Ge Quantum Well Heterostructures Grown on Industrial SiGe‐Buffered Wafers

open access: yesAdvanced Science, EarlyView.
Hyperfine coupling to 29Si$^{29}{\rm Si}$ and 73Ge$^{73}{\rm Ge}$ nuclear spins limits hole spin‐qubit coherence in Ge heterostructures. We demonstrate device‐grade, nuclear‐spin‐free 70Ge$^{70}{\rm Ge}$/28Si70Ge$^{28}{\rm Si}^{70}{\rm Ge}$ quantum wells grown on industrial SiGe buffers with minimal use of enriched precursors.

Shell Model Study of the Neutron-Rich Nuclei around N=28 [PDF]

open access: yes, 1996
We describe the properties of the neutron rich nuclei around N=28 in the shell mode framework. The valence space comprises the $sd$ shell for protons an the $pf$ shell for neutrons without any restriction.

How to produce new superheavy nuclei?

open access: yes, 2019
Existing experimental facilities limit the possibilities for discovery of new nuclides to those synthesized with cross sections above 100 fb, but the perspectives for future high current accelerators could lower this limit by two orders of magnitude ...

Enhancing the d–Electrocatalytic Activity of MXene Through Defect Engineering

open access: yesCarbon Energy, EarlyView.
Applications of MXene. ABSTRACT Due to their versatile and tunable surface and bulk chemistry, MXenes have great potential as electrocatalysts for batteries and supercapacitors. When compared with other electrocatalytic processes, in electrocatalytic reactions, MXenes could improve ion diffusion and charge transfer by either providing functional groups
