M.Chem. Chemistry and Nanotechnology, M.Sc. Research Chemical Engineering
Liam Critchley is a writer and journalist who specializes in Chemistry and Nanotechnology. Liam’s scientific career started off by undertaking two master’s degrees. The first was a 4-year MChem in Chemistry and Nanotechnology from the University of Hull, which was followed by an MSc by Research in Chemical Engineering from the University of Birmingham.
Liam worked on various research projects at some the highest ranking Chemistry and Chemical Engineering departments for academic research in the UK. One of the research projects included creating polyoxovanadate molecular magnets under anaerobic conditions from calixarene precursor materials; scaling up the production of air-filled emulsions from the bench to pilot scale (for the first time). The project achieved a bench scale yield of up to 98.7% and producing polymer-based scaffolds for the proliferation of stem cells in tissue engineering applications.
Liam chose to step out of academic research and went straight into freelancing as a science writer. Aside from wanting to work in an area where this knowledge could be put to good use, Liam chose to take up freelancing as his career so that he could travel around the world with his family.
As a writer, Liam provides an informative approach, explaining complex scientific topics to both scientists and non-scientists. Liam has over 350 articles published to date across various scientific areas and industries - with over 200 articles located across all the AZo websites, including News Medical.
Liam also holds the position of Senior Science Communications Officer at the Nanotechnology Industries Association (NIA) and has spent the last few years providing writing and editing services for companies, associations and media websites located across the globe.
Aside from writing, Liam is also a Member of the Advisory Board for the National Graphene Association (NGA) in the U.S. and is a Member of the Board of Trustees for GlamSci – a UK-based science charity. Liam is also a member of the British Society for Nanomedicine (BSNM) and the International Association of Advanced Materials (IAAM), as well as a peer reviewer for multiple academic journals.
This article describes the methods required to set up a variety of schlieren optics.
This article gives a basic introduction of quantum optics, following the emergence of quantum-based applications in recent years.
Scanning Spreading Resistance Microscopy (SSRM) is a variation of AFM that employs a conductive tip in contact mode to measure the resistance of a surface in combination with a high force.
Scanning capacitance microscopy (SCM) is a technique that takes operational principles from both atomic force microscopy (AFM) and scanning probe microscopy (SPM).
In MFM, the tip detects the magnetic interactions at the surface of the material and builds up a spatial distribution map of the material’s magnetic structure.
EFM is one of the few methods where it is an adaptation of just AFM principles for deducing specific properties of materials.
C-AFM is a type of AFM mode that uses a sharp conductive tip (often a conductive diamond-coated silicon tip).
AFM has become a widely used technique for many reasons. It is most frequently used to determine the topography of a surface.
Atomic force microscopy (AFM) is a powerful and versatile microscopy technique that has been used across many scientific disciplines for decades. While it is a single technique, there are many ways in which it can be used.
Piezoresponse force microscopy (PFM) is a variation of atomic force microscopy (AFM) that uses a conductive probe tip to measure the piezoelectric, and more commonly the ferroelectric, domains of a material.
The Thermo Scientific™ ARL™ EQUINOX 3000 X-ray Diffractometer for research enables accurate measurements.
KLA’s Filmetrics F40 allows you to transform your benchtop microscope into an instrument to measure thickness and refractive index.
This product profile describes the properties and applications of the ProMetric® I-SC Solution Imaging Colorimeter.
