Ben Muller joined JEOL’s SEM applications team in late September, and in that short time has already taught two classes and assisted several customers with applications support and sample preparation work.

NMR data contains a trove of useful information for answering a wide variety of chemical and biological problems. However, with this broad utility comes complexity. CRAFT uses a Bayesian statistical approach to convert NMR time-domain data directly to the tabular domain. This bypasses the artifacts created by the Fourier transform when producing the spectrum and makes the automated extraction of these chemical shift and intensity data tables more reliable. With CRAFT, the spectrum (or frequency-domain data) is simply a human visualization tool for the data tables.

That’s the problem that 8th (now 9th) grade students at Concord-Carlisle Middle School, in collaboration with Massachusetts Institute of Technology and JEOL USA, set out to solve when they responded to a NASA challenge for the development of innovative technologies to support human colonization of Mars by 2050.

Traditional SEM instruments have provided us with unprecedented details of every surface you can think of, from whole insects to crystals and bacteria, but can be complex to use, requiring specialist knowledge, and also require a large dedicated space. The dawn and advancement of compact and user-friendly benchtop SEMs however is changing this picture.

Entitled “Nano Nemo on the Water,” entry was selected as the winner of the Grand Prize SEM Image category in JEOL’s image contest for 2017.

Cian has submitted 3 images that are all relevant to platinum nanostructures. We thought that the patterns that they form were interesting, so we asked the PhD candidate about his work with platinum.

What makes the difference between a good SEM image and a stellar one? Imaging samples at the appropriate conditions, and that often means at very low accelerating voltage (low kV). It's time to give it a try!
