Supplementary Dataset for Thesis: Bridging the Gap in Sustainable Continuous Chemicals Manufacture: Integrating Upstream Synthesis and Downstream Crystallisation - Chapter "Thermochromics"
The dataset includes the videos recorded for hot-stage microscopy measurements of cocrystal systems: 4-bromo-2-methylaniline:3,5-dinitrobenzoic acid (4Br2MA:35DNBA) and 4-iodo-2-methylaniline:3,5-dinitrobenzoic acid (4I2MA:35DNBA) isolated from slow evaporation and antisolvent crystallisation (batch and flow) experiments which is discussed in the Thesis Chapter.
The video demonstrates the co-crystals systems colour changing properties and phase transition behaviour in response to temperature as well as the co-crystal melting points.
TC1.8 and Cc4 concern 4I2MA:35DNBA cocrystals and TC3.1, TC3.4, TC4.1 TC4.2, TC4.3 and TC4.4 correspond to 4Br2MA:35DNBAReal-time analysis of phase transitions was conducted using a Mettler Toledo FP82 hot stage equipped with a Leica DM1000 microscope. A small amount of sample was placed onto a glass slide and transferred to the hot stage chamber. The sample was then subjected to a temperature program using the FP90 Central Processor. The microscope was equipped with an Infinity 2 camera to record any changes in real time. The Studio86Designs software was used capture the video. Playback of the videos was carried out using Studio Player.
In a typical experiment, a sample is heated at 5 C per min from a start temperature of 35 C until the sample has visibly melted. The video would be logged and played back to observe any visible changes in colour; a loss of crystallinity; solvent precipitation or a melting point over a specific temperature range.
In samples subjected to water, 20 uL deionised water was added to the sample on the glass slide before being subjected to hot stage microscopy.Playback software capable of reading avi. files - e.g. VLC media playe
Dataset for "Continuous flow for materials synthesis, assembly and crystallisation at Diamond: discovery and delivery of high value materials"
Continuous crystallisation of the model system Carbamazepine (CBZ) in ethanol in the KRAIC-D (Kinetically Regulated Automated Input Crystalliser - Diffraction) platform on beamline I11 (high resolution powder diffraction) is presented. The effect of introducing a controlled solid interface into the crystallisation process is investigated, where CBZ form III seeds are introduced in polymorphic purity at different seeding positions (pre- and post-nucleation) throughout the length of the KRAIC-D. The video associated with Chapter 4 corresponds with a post-nucleation CBZ form III experiment where a separation of crystal habit is observed as a result of the different interaction with the flow paths in the solution slugs with the segmented flow.
The second device is the KRAIC-S (Kinetically Regulated Automated Input Crystalliser - Single Crystal) platform installed at I19 (small molecule single crystal beamline) employed to investigate the continuous crystallisation of paracetamol (PCM) in 60:40 water:isopropanol via a range of experiments including unseeded and seeded cooling crystallisations. The unseeded experiments also looked at the crystallisation at different set points along the KRAIC-S (6.7 m and 8.7 m) to investigate crystal growth and crystal rotation at different length scales. The videos associated with Chapter 5 include single crystals produced from the range of experiments investigated. Each video tracks a different single crystal in a solution slug, where through use of the slug triggering mechanism, whereby an optical trigger prompts translation of the motorised stage to artificially suspend the single crystal in the X-ray beam during data collection. These videos complement the diffraction data and can provide explanation for data collections, which do not achieve cell indexation as the single crystal is shown to move in and out of the X-ray beam in these videos.Videos obtained using Camera positioned by X-ray beam on beamline I19, the small molecule single crystal beamline at Diamond Light Source
Underreporting of drug industry payments to patient organisations in the UK (2012-2016)
This online dataset comprises web supplements (WS) accompanying the paper entitled “An underreported relationship: a comparative study of pharmaceutical industry and patient organisation payment disclosures in the UK (2012-2016)”.
The dataset includes aggregated information from
1. yearly disclosure reports published by 63 UK-based drug companies including payments made to patient organisations;
2. yearly financial accounts produced by 200 UK-based charities and published on charity regulator websites.
The data is divided into web supplements 3-20 which are signposted throughout the Results section of the above-mentioned article as “web supplement XX”.The methodology is described in full in the Data sources and extraction section of the paper entitled "An underreported relationship: a comparative study of pharmaceutical industry and patient organisation payment disclosures in the UK (2012-2016)".
In brief, the data collection process involved downloading disclosure reports including payments to patient organisations made by a sample of 108 companies participating in the Disclosure UK initiative in 2016 (https://www.abpi.org.uk/our-ethics/disclosure-uk/). We subsequently searched for the annual accounts of patient organisations identified in drug company payment disclosure reports on the websites of the three UK charity regulators, that is the Charity Commission for England and Wales (https://www.gov.uk/government/organisations/charity-commission), the Scottish Charity Regulator (https://www.oscr.org.uk/) and the Charity Commission for Northern Ireland (https://www.charitycommissionni.org.uk/). The payment data from drug company payment disclosure reports and charity annual accounts was extracted into two separate Excel spreadsheets.
We subsequently combined payment records form the two spreadsheets into a single excel spreadsheet comprising a series of drug company by patient organisation matrices corresponding with different types of analysis carried out as part of our research study.
In total, this online dataset comprises 17 web supplements with the results of calculations based on these matrices. The web supplements correspond with and provide additional background information for specific subsections in the Results section of the article entitled "An underreported relationship: a comparative study of pharmaceutical industry and patient organisation payment disclosures in the UK (2012-2016)".The data was created using Excel (primarily "countifs", "sumifs", and "V-lookup" functions)The data is organised into 17 appendices which correspond with specific parts of the Results section of the paper entitled "An underreported relationship: a comparative study of pharmaceutical industry and patient organisation payment disclosures in the UK (2012-2016)"

Dataset for 'Zn doped Fe2TiO5 photoanodes grown by aerosol-assited chemical vapor deposition'
This dataset includes a range of experimental data collected. In particular, raw data from X-Ray diffraction patterns (XRD), UV- Vis spectroscopy, X-Ray Photoelectron Spectroscopy (XPS), linear sweep voltammetries, photcurrent times curves, IPCE and electrochemical impedance spectroscopy (EIS). Specifics of the methology employed for data collection is described in detail in the experimental part of the paper. Raw data has been labeled following the same methodology as in the paper.Physical Characterisation
X- ray diffraction (XRD) patterns were collected from 10 to 60° (2θ) using a Bruker D8 diffractometer with Cu Kα (0.154 nm) radiation.
Raman spectroscopy was performed on a Renishaw inVia system using a 532 nm diode-pumped solid-state laser (DPSS) manufactured by Cobolt. A 50x long distance objective was used to focus the laser beam onto the sample.
UV-Vis measurements were carried out in a Lambda 950 spectrometer (Perkin Elmer) with an integrating sphere (150 mm InGaAS). The samples were mounted in the center. Diffuse-reflectance UV-Vis measurements were performed in an Agilent Cary 100 spectrophotometer.
X-ray photoelectron spectroscopy (XPS) was performed with a monochromatic Al Kα X-ray-source (1486.74 eV, Specs Focus 500 monochromator). C 1s was used for internal charge correction. Ultraviolet photoelectron spectroscopy (UPS) was carried out with a He I source (E = 21.218 eV) in the same chamber. A hemispherical analyzer (Specs Phoibos 100) was used for both XPS and UPS measurements. The base pressure of the system was ∼10−9 mbar.
(Photo)electrochemical characterisation:
Photoelectrochemical (PEC) performance of photoanodes was measured under simulated solar light using a WACOM Super Solar Simulator (Model WXS-505-5H, AM 1.5, Class AAA) and an EG&G Princeton Applied Research Potentiostat/Galvanostat (Model 273A). PEC cells were prepared using a three electrode configuration with Pt as the counter electrode, a silver chloride reference electrode (Ag/AgCl-reference electrode, XR300, Radiometer Analytical, EAg/AgCl=0.197 VRHE) and the as-prepared photoanodes as the working electrode. Illumination was directed towards the back of the photoanode (Glass-FTO-sample). 1 M NaOH (pH=13.6) was used as electrolyte.
Incident photon-to-current efficiency (IPCE) measurements were performed using an Xe lamp (LOT, LSH302), an Acton Research monochromator (Spectra Pro 2155) and an electronic shutter (Uniblitz LS6). The intensity of the monochromated light was measured by a calibrated photodiode (PD300R-UV, Ophir) just after a clean FTO-glass substrate placed at the working electrode position, in the absence of PEC cell quartz window or PEC cell electrolyte.
PEC impedance spectroscopy (PEIS) was carried out under simulated sunlight (AM 1.5G, 100 mW cm-2) using a CompactStat. Potentiostat (Ivium technologies). Measurements were performed in a frequency range from 105 to 0.1 Hz, with an AC voltage amplitude of 10 mV at a potential range of 0.6 to 1.2 VRHE with 0.05V steps, in 1M NaOH. EIS measurements in the dark were also measured to obtain Mott-Schottky plots. These measurements were performed at a fixed frequency of 100 and 1000 Hz.Data for the different technqiues are presented in different documents. Data has been labeled as follows: #_Fe2TiO5, #_Fe2TiO5_Zn, #_Fe2O3 and #_Fe2O3_Zn, where # corresponds to the nomenclature of x and y axis of the plot

Dataset for Impact of Inductively Coupled Plasma Etching Conditions on the Formation of Semi-Polar (11-22) and Non-Polar (11-20) GaN Nanorods
The formation of gallium nitride (GaN) semi-polar and non-polar nanostructures is of importance for improving light extraction/absorption of optoelectronic devices, creating optical resonant cavities or reducing the defect density. However, very limited studies of nanotexturing via dry etching have been performed, in comparison to wet etching. In the paper associated with this dataset, we investigate the formation and morphology of semi-polar (11-22) and non-polar (11-20) GaN nanorods using inductively coupled plasma (ICP) etching. The impact of gas chemistry, pressure, temperature, radio-frequency (RF) and ICP power and time are explored. The scanning electron microscopy images contained in this dataset indicate that a chemical component of the etch process is found to have a significant impact on the morphology, being impacted by the polarity of the planes. In contrast, the images show that increasing the physical component enables the impact of crystal orientation to be minimized to achieve a circular nanorod profile with inclined sidewalls. These conditions were obtained for a small percentage of chlorine (Cl2) within the Cl2 + argon (Ar) plasma combined with a low pressure. Damage to the crystal was reduced by lowering the direct current (DC) bias through a reduction of the RF power and an increase of the ICP power.Full details of the methodology may be found in the Materials and Methods section of the associated paper.Secondary electron images were captured using a Hitachi S-4300 scanning electron microscope (SEM)
