TSPDF correlates variation in local structure with kinetic behavior in amorphous pharmaceutical formulations

Many newly discovered, and possibly life-saving, drug compounds do not possess sufficient solubility or permeability in the digestive tract to make it to production status. Amorphous and nanocrystalline drug dispersions are being developed to overcome these issues but result in secondary issues with product stability. In a recent report, we have used the total scattering… Read More TSPDF correlates variation in local structure with kinetic behavior in amorphous pharmaceutical formulations

PDF combined with SCXRD solves the atomic structure of tetrahedral quantum dots

Luminescent semiconducting quantum dots (QDs) are central to emerging technologies that range from tissue imaging to solid-state lighting. However, existing samples are heterogeneous, which has prevented atomic-resolution determination of their structures and obscured the relationship between their atomic and electronic structures. In this work, we synthesized, isolated and structural characterized  three cadmium selenide QDs with… Read More PDF combined with SCXRD solves the atomic structure of tetrahedral quantum dots

PDF unveils the structure of organic-inorganic perovskite solar cell

For the first time, the  detailed structure of the light harvesting material in recently discovered high performance  dye sensitized solar cells (DSSCs) has been determined. There has been a strikingly rapid increase in the performance of solar cells based on methylammonium lead iodide (MAPbI3) perovskites following the first report in 2009; today greater than 15%… Read More PDF unveils the structure of organic-inorganic perovskite solar cell

PDF reveals structure of miracle perovskite in novel solar cells

For solar electricity to be economically competitive with fossil fuel based electricity, the cost of fabricating and installing solar cells needs to be much lower. Solution processed solar cells can potentially achieve this with a drastically lower fabrication cost but their low performance has so far limited their success. Recently, solar cells based on methylammonium… Read More PDF reveals structure of miracle perovskite in novel solar cells

PDF unveils the structure of important 2D nanocrystalline MXene materials

MXenes are emerging 2-D materials that are extremingly promising for applications in electronic and energy storage devices (Science 341, 1502, 2013; Nat. Commun. 4, 1716, 2013). However, due to their nanomaterial nature, it has proven impossible to solve their structures by means of traditional x-ray crystallography. Atomic pair distribution function technique (PDF), on the other… Read More PDF unveils the structure of important 2D nanocrystalline MXene materials

PDF makes important contribution to understanding of solar-driven catalytic hydrolysis

It will take state-of-art nanoparticle catalysts to harness sunlight to split water, a holy grail of energy research, into hydrogen and oxygen, green fuels with the potential to satisfy the ever-increasing demand for energy. Due to the catalysts’ nanostructured nature, their structures are unknown, which poses a great challenge for understanding their function. Recently, Billinge… Read More PDF makes important contribution to understanding of solar-driven catalytic hydrolysis
