Meet the team at Granta Design

The second in a series in which we meet the Granta team. We spoke with our colleague Pippa, to find out what she enjoys about being an Education Account Manager, and which scientist and material inspires her most. We’re always looking for like-minded individuals who have passion and drive to make positive change to our educational practices, take a look at our current opportunities if you think this could be you.

“As a member of the Education division I work with universities and colleges across the globe including the UK, Netherlands, Singapore, and Australia. I support them in the use of both CES EduPack and CES Selector, for teaching and research respectively, from initial engagement to see if the software will help their current teaching right through to advising them on the deployment and use of the software.

How Cook Medical’s regulatory team uses materials data

How Cook Medical’s regulatory team uses materials data

 

This week, I presented in a collaborative webinar with Cook Medical’s David Chadwick, Director of Regulatory Affairs, covering the best practise when applying materials data and predicate device information in healthcare. The healthcare industry faces a colossal task when choosing materials for use in new or existing medical devices. For those unfamiliar with the medical industry, the number of factors which need to be carefully considered when selecting a material for use in the human body can seem overwhelming; engineering properties, biocompatibility, effect of sterilization treatments, material-drug interactions, regulatory approval processes such as FDA approval and CE Marking, just to name a few.

Poly(methyl methacrylate): a biocompatible acrylic

medicalDiscovered in 1877 and patented in 1933, PMMA, or acrylic, is often used as a lighter, more shatter-resistant alternative to glass. It is easy to process and make, resulting in a low cost versatile material used for everything from windows in aquariums, to protecting the audience from stray pucks in ice hockey rinks, and even in shoes.

What is interesting about PMMA, though, is its biocompatibility. Despite being formed by polymerizing Methyl Methacrylate, an irritant, and possibly a carcinogen, PMMA is extremely biocompatible, resistant to long exposure to temperatures, chemistry and cell action of human tissue.

100 Years of Stainless Steel

oil-rigGranta’s recent trip to MS&T in Pittsburgh, the Steel City, reminded me that this year marks a hundred years since the invention of stainless steel, or at least since the first patents were granted to Strauss and Maurer in 1912 for the austenitic stainless steel they branded Nirosta. At about the same time in Sheffield, England, Harry Brearley discovered a corrosion resistant martensitic alloy which, although designed for gun barrels, first found fame                                     as the new, shiny entrance canopy material for the Savoy Hotel.
