ALERT: This system is being upgraded on Tuesday December 12. It will not be available
for use for several hours that day while the upgrade is in progress. Deposits to DukeSpace
will be disabled on Monday December 11, so no new items are to be added to the repository
while the upgrade is in progress. Everything should be back to normal by the end of
day, December 12.

A Model Elastomer with Modular Metal-Ligand Crosslinking
(2022)Metallosupramolecular polymers are increasingly of interest for functional and degradable polymeric materials. In these materials, the metal-ligand bonds often bear an external mechanical load, but little is yet understood ... -
Active Surfaces and Interfaces of Soft Materials
(2014)A variety of intriguing surface patterns have been observed on developing natural systems, ranging from corrugated surface of white blood cells at nanometer scales to wrinkled dog skins at millimeter scales. To mimetically ... -
Bridging Molecular Mechanochemistry and Network Fracture Mechanics
(2022)The fracture of polymer networks is usually perceived macroscopically and is considered as a mechanical engineering problem. However, to advance a crack in a polymer network, lots of polymer strands that bridge the crack ... -
Controlling and Exploiting Spiropyran-based Mechanochromism
(2019)When mechanical force is applied to synthetic materials, polymer chains becomehighly strained, leading to bond scission and ultimately material failure. Over the lastdecade or so, work in the field of polymer mechanochemistry ... -
Covalent mechanochemistry of four-membered carbocycles
(2021)The development of multi-mechanophore polymers (MMPs) has empowered new methodologies for observing and quantifying mechanochemical transformations. Previously developed techniques such as single-molecule force spectroscopy ... -
Electrogenetics: Genetically Encoded Electrophysiology
(2022)There are about 86 billion neurons in the human brain, connected by trillions of synapses. Deciphering the electrical signaling between neurons is key to understanding the brain in both health and disease. As understanding ... -
Extended, Localized, and Tailorable Delivery of Therapeutics from Poly(ester urea) Systems
(2023)Adequate pain management within the first 3-5 days following a procedure is vital to the enhancement of patient healing and recovery. The current gold standard for relieving post operative pain consists of oral medication ... -
From Molecular to Macroscopic Mechanochemical Responses
(2020)The key concept of polymer mechanochemistry is the rational design of mechanophores. When incorporated into polymeric materials, mechanophores can be used to produce strain-dependent covalent chemical responses, including ... -
Intrinsically Disordered Protein Polymer Libraries as Tools to Understand Protein Hydrophobicity
(2019)Intrinsically disordered protein polymers (IDPPs) are repetitive biopolymers that, when enriched with prolines, glycines, and aliphatic amino acids, have observable lower critical solution temperature (LCST) phase transition ... -
Mechanochemistry for Active Materials and Devices
(2016)The coupling of mechanical stress fields in polymers to covalent chemistry (polymer mechanochemistry) has provided access to previously unattainable chemical reactions and polymer transformations. In the bulk, mechanochemical ... -
Metal-Ligand Interactions in Stimuli Responsive Molecules
(2018)The ability to control changes in physical and chemical properties has allowed stimuli responsive molecules to be used in a variety of applications. Incorporating metals into stimuli responsive molecules introduces properties ... -
Molecular-Level Engineering of Stress-Responsive Materials
(2020)The insertion of force-sensitive motifs (mechanophores) into polymer backbones provides a mechanism to induce forbidden reactions, stabilize transition state, and build intrinsic stress-responsive materials. Although polymer ... -
Polymer Remodeling Enabled by Covalent Mechanochemistry
(2013)Material failure is a ubiquitous problem, and it is known that materials fail at much lower stresses than the theoretical maximum calculated from the number and strength of the individual bonds along the material cross-section. ... -
Polysequence Nanomaterials for Immunomodulation
(2021)Peptide-based vaccines have received growing interest due to their specificity and ability to limit off-target effects, and they are currently being explored toward a variety of infectious diseases and therapeutic targets. ... -
Probing Mechanical Activation of Covalent Chemistry in Crosslinked Polymer Gels
(2013)Toughness, the measure of how much energy a material can absorb before rupture, is an important property of materials. It has been demonstrated that the toughness of a single polymer chain of <italic>gem</italic>-dihaloc... -
Structure Activity Relationships in the Fracture of Hybrid Covalent/Metallosupramolecular Organogels
(2014)Hybrid polymeric networks constructed using both covalent and reversible cross-links have been shown to be effective in preventing fracture and ultimately failure in polymeric materials. The prevention of failure has been ...
