Spontaneous hierarchical assembly of crown ether-like macrocycles into nanofibers and microfibers induced by alkali-metal and ammonium salts.

Chemistry (Weinheim an der Bergstrasse, Germany)

Hui JK, Frischmann PD, Tso CH, Michal CA, Maclachlan MJ.
PMID: 20066701
Chemistry. 2010 Feb 22;16(8):2453-60. doi: 10.1002/chem.200902712.

Schiff base macrocycle 1, which has a crown ether like central pore, was combined with different alkali-metal and ammonium salts in chloroform, resulting in one-dimensional supramolecular aggregates. The ion-induced self-assembly was studied with solid-state NMR spectroscopy, transmission electron microscopy...

Increasing the dimensionality of cryogenic molecular coolers: Gd-based polymers and metal-organic frameworks.

Chemical communications (Cambridge, England)

Lorusso G, Palacios MA, Nichol GS, Brechin EK, Roubeau O, Evangelisti M.
PMID: 22729217
Chem Commun (Camb). 2012 Aug 07;48(61):7592-4. doi: 10.1039/c2cc33485b. Epub 2012 Jun 25.

The magnetothermal properties of a coordination polymer and a metal-organic framework (MOF) based on Gd(3+) ions are reported. An equally large cryogenic magnetocaloric effect (MCE) is found, irrespective of the dimensionality. This combined with their robustness makes them appealing...

BACKGROUND: There are very few long-term Canadian data on breast cancer outcomes by stage. We described the stage, treatment and outcomes of breast cancer at a population level for patients in British Columbia.METHODS: This population-based cohort study included almost...

Cell-laden microengineered pullulan methacrylate hydrogels promote cell proliferation and 3D cluster formation.

Soft matter

Bae H, Ahari AF, Shin H, Nichol JW, Hutson CB, Masaeli M, Kim SH, Aubin H, Yamanlar S, Khademhosseini A.
PMID: 21415929
Soft Matter. 2011 Jan 01;7(5):1903-1911. doi: 10.1039/C0SM00697A.

The ability to encapsulate cells in three-dimensional (3D) environments is potentially of benefit for tissue engineering and regenerative medicine. In this paper, we introduce pullulan methacrylate (PulMA) as a promising hydrogel platform for creating cell-laden microscale tissues. The hydration...

Extending lead-free hybrid photovoltaic materials to new structures: thiazolium, aminothiazolium and imidazolium iodobismuthates.

PMID: 29741166
Dalton Trans. 2018 May 22;47(20):7050-7058. doi: 10.1039/c8dt00864g.

We report on the synthesis, crystal structures, optoelectronic properties and solar cell device studies of three novel organic-inorganic iodobismuthates - [C3H4NS]3[Bi2I9] ([TH]3[Bi2I9]), [C3H4N2]3[Bi2I9] ([IM]3[Bi2I9]) and [C3H5N2S][BiI4] ([AT][BiI4]) as lead-free light harvesters. [TH]3[Bi2I9] and [IM]3[Bi2I9] show zero-dimensional structures, whereas a...

Severe Late Toxicity After Adjuvant Breast Radiotherapy in a Patient with a Germline Ataxia Telangiectasia Mutated Gene: Future Treatment Decisions.

Cureus

Dosani M, Schrader KA, Nichol A, Sun S, Shenkier T, Lohn Z, Aubertin G, Tyldesley S.
PMID: 28929041
Cureus. 2017 Jul 11;9(7):e1458. doi: 10.7759/cureus.1458.

Ataxia telangiectasia mutated (ATM) gene mutations may confer increased sensitivity to ionizing radiation and increased risk of late toxicity for cancer patients. We present the case of a 55-year-old female treated with adjuvant breast and regional nodal radiation following...

Cages on a plane: a structural matrix for molecular 'sheets'.

Bio-inspired Domino oxa-Michael/Diels-Alder/oxa-Michael Dimerization of para-Quinols.

Angewandte Chemie (International ed. in English)

Green NJ, Connolly CA, Rietdijk KPW, Nichol GS, Duarte F, Lawrence AL.
PMID: 29637681
Angew Chem Int Ed Engl. 2018 May 22;57(21):6198-6202. doi: 10.1002/anie.201802125. Epub 2018 Apr 25.

A bio-inspired, pyrrolidine-mediated, dimerization of para-quinols has been developed. It represents one of the most complex, yet general, dimerization reactions ever disclosed, selectively forming four new bonds, four new rings, and eight new contiguous stereogenic centres. The para-quinol starting...

Oxidative addition of inert bonds at low-valent main-group centres is becoming a major class of reactivity for these species. The reverse reaction, reductive elimination, is possible in some cases but far rarer. Here, we present a mechanistic study of...

Noncovalent encapsulation is an attractive approach for modifying the efficacy and physiochemical properties of both therapeutic and diagnostic species. Abiotic self-assembled constructs have shown promise, yet many hurdles between in vitro and (pre)clinical studies remain, not least the challenges...
