Working with Reactive, Volatile, Complex Materials to Produce Novel Alloys

Technologies are an integral part of our lives and we rely on them for such things as communication, heating and cooling, transportation, and construction. Improvements to technologies have made what they do for us more precise, automated, efficient, and powerful.

Il team dei nostri ricercatori vanta grande esperienza in tutte le aree della ricerca quali Life Science, scienza dei materiali, sintesi chimica, cromatografia, discipline analitiche, ecc..
