This session is compulsory for all experimentalists to attend and will provide useful information regarding analytical facilities at this Department including NMR, mass spectrometry and X-ray crystallography. Short descriptions will be given of all available instruments, as well as explain the procedures for preparing/submitting samples for the analysis will also be discussed.

Chemistry: CT2 Fundamentals of Mass Spectrometry Mon 4 Nov 2019   10:00 Finished

Mass spectrometry is one of the main analytical-chemical techniques used to characterise organic compounds and their elemental composition. This overview will discuss some of the most frequently used mass spectrometry techniques and their specific strengths (e.g., quadrupole, time-of-flight and high-resolution MS), as well as ionisation techniques such as electron ionisation (EI), electrospray ionisation (ESI), matrix assisted laser desorption/ionisation (MALDI) and MS techniques to quantify metal concentrations (e.g. inductively coupled plasma MS, ICP-MS) and isotope ratios.

This training will consist of two sessions, introducing you to use of both Water's MS software and MassLynx and Bruker and Thermo's MS software: MALDI and Orbitrap.

Chemistry: CT4 Solution Phase NMR Spectroscopy Fri 8 Nov 2019   14:00 Finished

Nuclear Magnetic Resonance (NMR) spectroscopy represents one of the most informative and widely used techniques for characterisation of compounds in the solution and solid state. Most researchers barely tap into the potential of the experiments that are available on the instruments in the Department, so in this short course we will explore the basic concepts that will allow you to make the most of these powerful techniques for routine analysis, as well as introducing more specialised experiments.

Chemistry: CT5 Solid State NMR Spectroscopy Mon 11 Nov 2019   14:00 Finished

This course will provide an idea of what kind of scientific problems can be solved by solid state NMR. It will cover how NMR can be used to study molecular structure, nanostructure and dynamics in the solid state, including heterogeneous solids, such as polymers, MOFs, energy-storage and biological materials This course will build on a basic working knowledge of solution-state NMR for 1H and 13C, i.e. undergraduate level NMR. In order to highlight the utility of this technique, some materials based research using solid state NMR will also be covered

The session will also give an insight into some of the more advanced features of the software, and how to optimise your workflow.

Chemistry: CT7 X-Ray Crystallography Tue 12 Nov 2019   14:00 Finished

These lectures will introduce the basics of crystallography and diffraction, assuming no prior knowledge. The aim is to provide an overview that will inspire and serve as a basis for researchers to use the Department’s single-crystal and/or powder X-ray diffraction facilities or to appreciate more effectively results obtained through the Department’s crystallographic services. The final lecture will be devoted to searching and visualising crystallographic data using the Cambridge Structural Database system.

Chemistry: CT8 Electron Microscopy Thu 5 Dec 2019   14:00 CANCELLED

This lecture will provide an overview of the Department’s electron microscopy facility. It will cover the theory of Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM), including cryo-TEM and tomography, as well as analytical techniques Energy-dispersive X-ray spectroscopy (EDX) and Electron Energy Loss Spectroscopy (EELS). Examples of how these techniques can be used to characterise a range of samples including polymers, proteins and inorganic materials will be shown.

Chemistry: CT9 Atomic Force Microscopy Mon 18 Nov 2019   10:00 Finished

Since introduction in 1986 by Binnig, Quate and Gerber, atomic force microscopy (AFM) has emerged as one of the most powerful scanning probe microscopy technique. The possibility to acquire three-dimensional morphology maps of specimens on a surface in both air and in their native liquid environment with sub-nanometre resolution makes it a very versatile single molecule technique. A conventional AFM topography map provides valuable information on the morphology and structure of heterogeneous biological samples, while single molecule force spectroscopy can interrogate the biophysical and nanomechanical properties of the sample at the nanoscale. Furthermore, the combination of AFM with spectroscopic modes enable to enquire the optical properties of the sample with nanoscale resolution. In these introductory lectures, the general capabilities of AFM with respect to other scanning probe and electron microscopy techniques will be discussed. The general principles governing the functioning of AFM in contact and tapping mode will be given, as well as the principles enabling the study of nanomechanical properties of samples by force spectroscopy and nanomechanical imaging. Other modes such as scattering SNOM, AFM-IR and Raman will be generally discussed. The course will provide the necessary background to acquire a morphology map by AFM. The last session will consist of a hand-on session introducing the students to the use and functioning of an AFM instrument.

Chemistry: DD10 Process Chemistry Workshop new Tue 3 Mar 2020   10:00 Finished

In this session, Dr. Mukund S. Chorghade will discuss the pivotal role played by Process Chemistry / Route Selection in the progress of a drug from conception to commercialization. The medicinal chemistry routes for synthesis are usually low yielding and are fraught with capricious reactions, cryogenic temperatures, tedious chromatography and problems in scale-up to multi-kilo and multi-ton levels. Considerable research efforts have to be expended in developing novel, cost efficacious and scalable processes and seamlessly transferring these technologies to manufacturing operations. These principles will be exemplified by process development case studies on a variety of pharmaceutical moieties such as anti-epileptic and an anti-asthma drugs. We were able to also discover a large number of New Chemical Entities by our new “Process Chemistry Driven Medicinal Chemistry”

We will exemplify advances in proprietary in vitro green chemistry-based technology, mimicking in vivo metabolism of several chemical entities used in pharmaceuticals, cosmetics, and agrochemicals. Our catalysts enable prediction of metabolism patterns with soft-spot analysis Metabolites are implicated in adverse drug reactions and are the subject of intense scrutiny in drug R&D. Present-day processes involving animal studies are expensive, labor-intensive and chemically inconclusive. Our catalysts (azamacrocycles) are sterically protected and electronically activated, providing speed, stability and scalability. We predict structures of metabolites, prepare them on a large scale by oxidation, and elucidate chemical structures. Comprehensive safety evaluation enables researchers to conduct more complete in vitro metabolism studies, confirm structure and generate quantitative measures of toxicity.
