A Bio‐Inspired Perspective on Materials Sustainability

Advanced Materials, EarlyView.
This perspective discusses natural materials as inspiration for sustainable engineering designs and the processing of materials. First, circularity, longevity, parsimony, and activity are presented as essential material paradigms. The perspective then uses many examples of natural and technical materials to introduce principles such as oligo ...

Intramolecular forces: the molecular structure and conformation of 2-cyclopropylpyridine and 4-cyclopropylpyridine

Journal of Molecular Structure, 2005
Abstract The molecular structure and conformation of 2-cyclopropylpyridine and 4-cyclopropylpyridine have been studied experimentally by gas-phase electron diffraction as well as by ab initio quantum chemical calculations. 2-Cyclopropylpyridine appears exclusively in the bisected form, with the cyclopropyl group pointing towards the nitrogen atom ...

Intramolecular Cation−π Interactions As the Driving Force To Restrict the Conformation of Certain Nucleosides

The Journal of Organic Chemistry, 2010
Despite the well-established importance of intermolecular cation-pi interactions in molecular recognition, intramolecular cation-pi interactions have been less studied. Here we describe how the simultaneous presence of an aromatic ring at the 5'-position of an inosine derivative and a positively charged imidazolium ring in the purine base drive the ...

Expanded Nanofibrous Cellulose Electrode Binder: Declustering Lithium Polysulfides for Lean‐Electrolyte Li‒S Batteries

Advanced Materials, EarlyView.
2,2,6,6‐Tetramethylpiperidin‐1‐oxyl radical (TEMPO)‐oxidized cellulose nanofiber (TOCN) is presented as a class of expanded nanofibrous electrode binders for lean‐electrolyte lithium–sulfur (Li–S) batteries. Owing to the increased active sites for intermolecular interaction with Li polysulfides (LiPS), the TOCN binder promotes the declustering of LiPS,

Functional Biomaterials Derived from Protein Liquid–Liquid Phase Separation and Liquid‐to‐Solid Transition

Advanced Materials, EarlyView.
Protein can undergo liquid–liquid phase separation and liquid‐to‐solid transition to form liquid condensates and solid aggregates. These phase transitions can be influenced by post‐translational modifications, mutations, and various environmental factors.
