TLDR
The geometry of simple knots and catenanes is described using the concept of linear line segments (sticks) joined at corners and this is extended to include woven linear threads as members of the extended family of knots.Abstract:
The geometry of simple knots and catenanes is described using the concept of linear line segments (sticks) joined at corners. This is extended to include woven linear threads as members of the extended family of knots. The concept of transitivity that can be used as a measure of regularity is explained. Then a review is given of the simplest, most ‘regular’ 2- and 3-periodic patterns of polycatenanes and weavings. Occurrences in crystal structures are noted but most structures are believed to be new and ripe targets for designed synthesis.read more

Nanoscale ATP-Responsive Zeolitic Imidazole Framework-90 as a General Platform for Cytosolic Protein Delivery and Genome Editing.
TL;DR: It was found that, in the presence of ATP, the ZIF-90/protein nanoparticles are degraded to release protein due to the competitive coordination between ATP and the Zn2+ of Zif-90.

Coordination-Directed Construction of Molecular Links.
TL;DR: This Review focuses on the role of metal-ligand paradigms in assembling molecular links and the ever-evolving approaches to efficient assembly, the structural features of the resulting architectures, and their prospects for the future.

Polymer Networks: From Plastics and Gels to Porous Frameworks.
TL;DR: A unifying overview of the fundamentals of polymer network synthesis, structure, and properties is provided, tying together recent trends in the field that are not always associated with classical polymer networks, such as the advent of crystalline "framework" materials.

A Single-Crystal Open-Capsule Metal-Organic Framework.
TL;DR: A new single-crystal capsular-MOF with openings on the wall, carefully designed at the molecular level and constructed from a crystal-structure transformation, which can easily load the largest amounts of sulfur and iodine among known MOFs.

Rod packings and metal-organic frameworks constructed from rod-shaped secondary building units.
TL;DR: The inclusion properties of the most open members are presented as evidence that MOF structures with rod building blocks can indeed be designed to have permanent porosity and rigid architectures.

The Reticular Chemistry Structure Resource (RCSR) Database of, and Symbols for, Crystal Nets
TL;DR: The underlying methodology of assigning symbols is explained and the Reticular Chemistry Structure Resource (RCSR) is described, in which about 1600 periodic nets are collected and illustrated in a database that can be searched by symbol, name, keywords, and attributes.
