Journal ArticleDOI
Clusters of superparamagnetic iron oxide nanoparticles encapsulated in a hydrogel: a particle architecture generating a synergistic enhancement of the T2 relaxation.
Chantal Paquet,Hendrick W. de Haan,Donald M. Leek,Hung-Yu Lin,Bo Xiang,Ganghong Tian,Ganghong Tian,Arnold J. Kell,Benoit Simard +8 more
TL;DR: This demonstration of a surface-active particle structure opens new possibilities in using similar structures for nanoparticle-based diagnostics using magnetic resonance imaging.
Journal ArticleDOI
Cucurbit[n]urils (n = 5–8): A Comprehensive Solid State Study
David Bardelang,Konstantin A. Udachin,Donald M. Leek,James C. Margeson,Gordon Chan,Christopher I. Ratcliffe,John A. Ripmeester +6 more
TL;DR: In this article, a self-closing effect was rationalized in terms of multiple weak CH···O interactions between the macrocycles, the degree of which is discussed in detail.
Journal ArticleDOI
Methanol incorporation in clathrate hydrates and the implications for oil and gas pipeline flow assurance and icy planetary bodies
Kyuchul Shin,Konstantin A. Udachin,Igor L. Moudrakovski,Donald M. Leek,Saman Alavi,Christopher I. Ratcliffe,John A. Ripmeester +6 more
TL;DR: A previously unverified role for methanol as a guest in clathrate hydrate cages is revealed and molecular dynamics calculations confirmed the possibility of meethanol incorporation into the hydrate lattice and show that methanian can favorably replace a number of methane guests.
Journal ArticleDOI
Unusual sculpting of dipeptide particles by ultrasound induces gelation.
David Bardelang,Franck Camerel,James C. Margeson,Donald M. Leek,Marc Schmutz,Md. Badruz Zaman,Kui Yu,Dmitriy V. Soldatov,Raymond Ziessel,Christopher I. Ratcliffe,John A. Ripmeester +10 more
TL;DR: A readily synthesized dipeptide shows unprecedented gelation behavior when dispersed and submitted to ultrasound in nonsolvents and maintains an anti conformation inside β-sheets at the molecular scale.
Journal ArticleDOI
Low-Temperature Approach to Highly Emissive Copper Indium Sulfide Colloidal Nanocrystals and Their Bioimaging Applications
Kui Yu,Peter Ng,Jianying Ouyang,Md. Badruz Zaman,Abedelnasser Abulrob,Toya Nath Baral,Dorothy Fatehi,Zygmunt J. Jakubek,David Kingston,Xiaohua Wu,Xiangyang Liu,Charlie Hebert,Donald M. Leek,Dennis M. Whitfield +13 more
TL;DR: This is a noninjection based approach in 1-dodecanethiol (DDT) with excellent synthetic reproducibility and large-scale capability and the bioimaging data illustrate that the CuInS2 NCs from the authors' SDPP-based low-temperature nonin injection approach are good quality.
