The nucleation and early stages of layer-by-layer growth of metal organic frameworks on surfaces

Peter Beton
High resolution atomic force microscopy (AFM) is used to resolve the evolution of crystallites of a metal organic framework (HKUST-1) grown on Au(111) using a liquid-phase layer-by-layer methodology. The nucleation and faceting of individual crystallites is followed by repeatedly imaging the same sub-micron region after each cycle of growth and we find that the growing surface is terminated by {111} facets leading to the formation of pyramidal nanostructures for [100] oriented crystallites, and triangular [111]...

Van der Waals-induced chromatic shifts in hydrogen-bonded two-dimensional porphyrin arrays on boron nitride

Peter Beton
The fluorescence of a two-dimensional supramolecular network of 5,10,15,20-tetrakis(4-carboxylphenyl)porphyrin (TCPP) adsorbed on hexagonal boron nitride (hBN) is redshifted due to, primarily, adsorbate-substrate van der Waals interactions. TCPP is deposited from solution on hBN and forms facetted islands with typical dimensions of 100 nm and either square or hexagonal symmetry. The molecular arrangement is stabilised by in-plane hydrogen bonding as determined by a combination of molecular-resolution atomic force microscopy performed under ambient conditions, and density functional...

Discovery of a novel polymer for human pluripotent stem cell expansion and multilineage differentiation - Supporting data 1

Adam Celiz, James Smith, Chris Denning & Morgan Alexander
A scalable and cost-effective synthetic polymer substrate that supports robust expansion and subsequent multilineage differentiation of human pluripotent stem cells (hPSCs) with defined commercial media is presented. This substrate can be applied to common cultureware and used off-the-shelf after long-term storage. Expansion and differentiation of hPSCs are performed entirely on the polymeric surface, enabling the clinical potential of hPSC-derived cells to be realized. Data presented herein includes time-of-flight secondary-ion mass spectrometry (ToF-SIMS), X-ray photoelectron spectroscopy...

Compounding and rheometry of PLA nanocomposites with coated and uncoated hydroxyapatite nanoplatelets

Magdalena M. Tomczynska
This is the research data for polylactic acid and novel nanoplatelets of hydroxyapatite (HANP) that were compounded in a laboratory scale twin-screw extruder and injection moulded to shape. The effect of HANP loading content, between 1 wt% and 10 wt%, and of HANP surface coating with tailored molecular dispersants, on processability and rheological behaviour were investigated. Dispersion of HANP within the matrix system was determined qualitatively using transmission electron micrographs. Surface coating of HANP with...

Institutional stakeholder interviews (Portland, Oregon) on the uncertainties, concerns and challenges the limit implementation of Blue-Green infrastructure

Colin Thorne
This is a qualitative data collection. These data were collected as part of an interdisciplinary project undertaken by the Blue-Green Cities (B-GC) Research Consortium with the Portland-Vancouver ULTRA (Urban Long-term Research Area) project (PVU), as part of the “Clean Water for All” initiative. The project examined the sources of uncertainty responsible for current concerns and challenges to widespread adoption of Blue-Green Infrastructure in urban flood risk management. The study consisted of eleven semi-structured interviews with...

Delivering green streets: an exploration of changing perceptions and behaviours over time around bioswales in Portland, Oregon

Jessica Lamond
Green Infrastructure (GI) is an increasingly popular means of dealing with flooding and water quality issues worldwide. This study examines public perceptions of, and behaviour around bioswales, which are a popular GI facility in the United States. Bioswales are highly visible interventions requiring support from residents and policy-makers to be implemented and maintained appropriately. To understand how residents’ perceptions and attitudes might develop over time we interviewed residents of Portland, Oregon, living near bioswales installed...

Discovery of a novel polymer for human pluripotent stem cell expansion and multilineage differentiation - Supporting data 2

James Smith
A scalable and cost-effective synthetic polymer substrate that supports robust expansion and subsequent multilineage differentiation of human pluripotent stem cells (hPSCs) with defined commercial media is presented. Data presented here shows cell adhesion to microarrays, scaled up surfaces, pluripotent marker expression and multilineage differentiation markers. Please note that this data set is in two parts, the first part of which can be found here: http://dx.doi.org/10.17639/nott.12
