Hello everyone!

I’m writing to announce a change in my program road-map, well actually the COLABS program itself is going to finish as expected on the 7th of August. Continue reading “COLABS update: project extended”

COLABS Update

COLABS Update

[EN-IT]

This is just a brief update.
As you know from the last update we had some interesting results, but now we have to link all those aspects (microstructure, magnetic susceptibility and so on) to find a pattern between the starting point, which are the powders, and the final properties of the sintered material.

COLABS update

[EN-IT]

Last update was two weeks ago already, and now I finally have some news…and exciting ones.

Basically in these two weeks I’ve been rushing to get everything done: I’ve been preparing new samples of even more concentrated alloys, I’ve been doing magnetic analysis, electron scanning and scattering, X-ray analysis and diffraction…
Lots of stuff, and the results are intriguing 😉 Continue reading “COLABS update”

COLABS update: last rush before the deadline

[EN]

I’ve been absent for quite long, I’ve been both busy and lazy, but here we have a new update.

Last time I talked about the promising results of the XRD analysis of my samples. After that almost two weeks have passed and I figured out what the unexpected peaks are (metastable intermetallics), measured the elastic modulus and the magnetic susceptibility of the samples.

As I wrote in my first article about my research the aim of the project is to obtain a novel alloy with a very low magnetic susceptibility and good mechanical properties to be used as an alternative to titanium in orthopedics. So the magnetic susceptibility is one of the most important results of my experiment. Continue reading “COLABS update: last rush before the deadline”

Now it’s high time for an update on my research work!

The last time I wrote I was still sintering my samples using Spark Plasma Sintering, I finished that part of the work as predicted before the beginning of May and after the Golden Week I started with the preparation of the specimens for the analysis.
It took a long time because both polishing and cutting are very slow, in particular the cutting part is very time demanding. I had to cut through every sample 8 times to produce the bars for mechanical tests and the specimens for XRD, TEM, EBSD, and every cut took 45 minutes with the fine cutter.

But finally last week I finished and now I’m performing the analysis! Continue reading “COLABS update”

How to domesticate a star

How to domesticate a star

[EN-IT]

The technology to control nuclear fusion is the next milestone of nuclear engineering, and it can lead to a number of useful applications.
First of all it will be possible to produce a massive quantity of electric energy while the world is getting hungrier and hungrier of electricity. Moreover since the feedstock for nuclear fusion is hydrogen and the products are low density elements like helium, it will be possible to produce power at relatively low footprint; that’s because hydrogen can be extracted from water or air while nowadays nuclear plants use rare and radioactive elements that need to be imported mainly from Africa.

Because of those (and other) reason the scientific community has long been trying to tackle the fusion problem: how to control the damn plasma. Continue reading “How to domesticate a star”

COLABS perspectives

COLABS perspectives

[EN-IT]

Well I haven’t been writing for a while now, and I’m not going to explain it here so let’s go straight to the point: COLABS.

As you know the COLABS program is what took me here so it’s the core of my exchange experience…well in this period I’m going to do some research around metals alloys for biomedical application, which fit perfectly what I’ve been studying for the last two years. Continue reading “COLABS perspectives”
