| Description | We have published four high-profile papers in Chemical Science, JACS (2) and Angewandte Chemie. We have submitted two further papers to Angewandte Chemie and Advanced Materials. In the latter manuscript, we show how to occlude ~500 nm diameter oil droplets within calcite. This is a remarkable achievement and we have filed an initial patent application with the University of Sheffield. As a result of this IP, P & G has agreed to partly-fund a CDT PhD studentship in this area to investigate whether this new technology may have potential commercial applications. |

| Title | Data associated with "Sub-Nanometer Thick Gold Nanosheets as Highly-efficient Catalysts" |
| Description | Two-dimensional metal nanomaterials offer exciting prospects in terms of their properties and functions. However, the ambient aqueous synthesis of atomically-thin, two-dimensional (2D) metallic nanomaterials represents a significant challenge. Herein, freestanding and atomically-thin gold nanosheets with a thickness of only 0.47 nm (two atomic layers thick) were synthesized via a one-step aqueous approach at 20°C, using Methyl Orange as a confining agent. Owing to the high surface-area-to-volume ratio, abundance of unsaturated atoms exposed on the surface and large interfacial areas arising from their ultrathin 2D nature, the as-prepared Au nanosheets demonstrate excellent catalysis performance in the model reaction of 4-nitrophenol reduction, and remarkable peroxidase-mimicking activity which enables a highly-sensitive colorimetric sensing of H2O2 with a detection limit of 0.11 µM. This work represents the first fabrication of freestanding 2D gold with a sub-nanometer thickness, opens up an innovative pathway towards atomically-thin metal nanomaterials that can serve as model systems for inspiring fundamental advances in materials science, and hold potential across a wide region of applications. |

| Title | Dataset for 'Controlling the fluorescence and room-temperature phosphorescence behaviour of carbon nanodots with inorganic crystalline nanocomposites' |
| Description | Dataset for Tuning Room-Temperature Phosphorescence from Carbon Dots in Inorganic Crystalline Nanocomposites. Carbon dots are occluded in calcite single crystal hosts and analysed by confocal microscopy, pXRD, SS-PL, phosphorescence spectroscopy, video stroboscopy, time-resolved phosphorescence microscopy, Raman spectroscopy, SEM, FLIM and quantitative analysis. The activation of room-temperature phosphorescence was demonstrated, and the control of the host over photoluminescent behaviour in CDs was explored. The dataset shown here was published in a paper with the same title. |

| Title | Dataset for Dichroic Calcite Reveals the Pathway from Additive Binding to Occlusion |
| Description | Dataset for all results concerning the occlusion for linear dyes in calcite, particularly that of Congo red. This includes photographs, micrographs and absorbance spectra. This data was used to show that linear dyes incorporate in an oriented way, such that their absorbance, and therefore colour, relates to the orientation of the crystal with respect to the plane of polarised light. |

| Title | Dataset for Skin-deep Patterning of Calcite |
| Description | Dataset for Skin-deep Patterning of Calcite. From the data in this file, we show that calcite surface patterning changes with experimental conditions, additive concentrations, time, additive mixtures and additive chemistry. As a model additive, we used a cement protein cp20k, to develop a range of surface patterns such as nanoshoots and arrowheads. From a range of other additives, we were then able to show how many other surface patterning motifs were then accessible. The data includes SEM, Optical, confocal fluorescence, FIB/SEM, and TEM data. |
