From formulation to structure: 3D electron diffraction for the structure solution of a new indomethacin polymorph from an amorphous solid dispersion
Autor: Helen W. Leung, Royston C. B. Copley, Giulio I. Lampronti, Sarah J. Day, Lucy K. Saunders, Duncan N. Johnstone, Paul A. Midgley
Publikováno v: IUCrJ, Vol 11, Iss 5, Pp 744-748 (2024)
3D electron diffraction (3DED) is increasingly employed to determine molecular and crystal structures from micro-crystals. Indomethacin is a well known, marketed, small-molecule non-steroidal anti-inflammatory drug with eight known polymorphic forms,

Changing the game of time resolved X-ray diffraction on the mechanochemistry playground by downsizing
Autor: Giulio I. Lampronti, Adam A. L. Michalchuk, Paolo P. Mazzeo, Ana M. Belenguer, Jeremy K. M. Sanders, Alessia Bacchi, Franziska Emmerling
Publikováno v: Nature Communications, Vol 12, Iss 1, Pp 1-9 (2021)
Time-resolved in situ (TRIS) X-ray powder diffraction promises great potential to study mechanochemical processes. Here, the authors develop a strategy to enhance the resolution of TRIS experiments to allow deeper interpretation of mechanochemical tr

Biomagnetic Characterization of Air Pollution Particulates in Lahore, Pakistan
Autor: H. A. Sheikh, B. A. Maher, V. Karloukovski, G. I. Lampronti, R. J. Harrison
Publikováno v: Geochemistry, Geophysics, Geosystems, Vol 23, Iss 2, Pp n/a-n/a (2022)
Abstract We report the characterization of anthropogenic magnetic particulate matter (MPM) collected on leaves from roadside Callistemon (bottlebrush) trees from Lahore, Pakistan, and on known sources of traffic‐related particulates to assess the p

Understanding the unexpected effect of frequency on the kinetics of a covalent reaction under ball-milling conditions
Autor: Ana M. Belenguer, Adam A. L. Michalchuk, Giulio I. Lampronti, Jeremy K. M. Sanders
Publikováno v: Beilstein Journal of Organic Chemistry, Vol 15, Iss 1, Pp 1226-1235 (2019)
We here explore how ball-mill-grinding frequency affects the kinetics of a disulfide exchange reaction. Our kinetic data show that the reaction progress is similar at all the frequencies studied (15–30 Hz), including a significant induction time be

Accurate extrinsic and intrinsic peak broadening modelling for time-resolved in situ ball milling reactions via synchrotron powder X-ray diffraction
Autor: Paolo P. Mazzeo, Giulio I. Lampronti, Adam A. L. Michalchuk, Ana M. Belenguer, Alessia Bacchi, Franziska Emmerling
Publikováno v: Faraday Discussions. 241:289-305
A state-of-the-art Rietveld refinement strategy is proposed to derive the instrumental resolution function (IRF) for a ball-mill setup for time-resolved in situ (TRIS) synchrotron XRPD.

Disappearing Polymorphs Reappear in the Mill: The Case of Ritonavir
Autor: Pietro Sacchi, Sarah Wright, Petros Neoptolemou, Giulio I. Lampronti, Ashwin K. Rajagopalan, Weronika Kras, Caitlin L. Evans, Paul Hodgkinson, Aurora J. Cruz-Cabeza
Organic compounds can crystallise in different forms known as polymorphs. Some polymorphs have disappeared from the physical world, never to be recrystallised again under the same conditions. The most infamous of these cases is that of the HIV drug r
