Effect of steric hindrance on the interfacial connection of MOF-on-MOF architectures
This work investigates how the interfacial strain effects occur in an interface of a MOF-on-MOF. The series of synthetic experiments and computational results revealed the importance of the proximity in each chemical connection point in a MOF-on-MOF system.

We present a novelty in the synthesis of 2D ultrathin silicon on Ag(111) and silicene-on-Ag(111) by molecular beam epitaxy.
About this collection
Guest Edited by Jin Zou (University of Queensland, Australia).
A key fabrication technique for nanoscale materials is the bottom-up approach. Epitaxial growth allows the grown nanostructures to have well defied orientation relationships, crystallographic directions/planes, crystal structures/phases, and facets/interfaces with their underlying substrates. Such unique features are often essential for securing their unique and high-efficient applications.
In the recent decades, epitaxial growth has been widely employed to grow various advanced nanostructures, including semiconductor nanostructures (such as quantum dots, semiconductor nanowires and quantum wells), 2D nanostructures (including ultra-thin nanosheets), and hierarchical nanostructured metal-organic frameworks (MOF-on-MOF).
This themed collection features work covering the development of these three groups of epitaxial nanostructures, in which their outstanding properties are obtained due to the epitaxy.
