The ultimate step towards a tailored engineering of core@shell and core@shell@shell nanoparticles

Nanoscale, 2014
Core@shell and core@shell@shell nanoparticles are building blocks for more sophisticated systems and a plethora of applications. The one-step generation of such complex nanoparticles is reported where the atoms of the core and shell can be easily inverted, avoiding intrinsic constraints of chemical methods.

Engineered inorganic core/shell nanoparticles [PDF]

Physics Reports, 2014
It has been for a long time recognized that nanoparticles are of great scientific interest as they are effectively a bridge between bulk materials and atomic structures. At first, size effects occurring in single elements have been studied. More recently, progress in chemical and physical synthesis routes permitted the preparation of more complex ...

Engineering of Yolk/Core–Shell Structured Nanoreactors for Thermal Hydrogenations [PDF]

Small, 2020
AbstractHeterogeneous hydrogenation reactions are of great importance for chemical upgrading and synthesis, but still face the challenges of controlling selectivity and long‐term stability. To improve the catalytic performance, many hydrogenation reactions utilize special yolk/core–shell nanoreactors (YCSNs) with unique architectures and advantageous ...

Egg-inspired engineering in the design of thin-walled shelled vessels: a theoretical approach for shell strength [PDF]

Frontiers in Bioengineering and Biotechnology, 2022
A novel subdiscipline of bionics is emerging in the form of ‘egg-inspired engineering’ through the use of egg-shaped ovoids as thin-walled tanks and building structures. Hügelschäffer’s and Narushin’s models of egg geometry are highly applicable within this proposed subdiscipline.
