Tailoring 2D semiconductor heterostructures with specific bandgaps is a key aspect of leveraging new quantum materials for electronics and optoelectronics, one of the hot topics for researchers currently working in nanotech. Craig Wall, applications scientist at Montana Instruments, recently investigated the subject using Mountains® software to analyze results from Raman spectroscopy and photoluminescence.
Bacterial infection of wounds is a major risk for patients undergoing skin grafts following severe burn injuries. Drs Monica Iliescu Nelea (left) & Michel Alain Danino, of the Plastic and Reconstructive Surgery Department at the University of Montreal Hospital Center (CHUM), Montreal, Canada are part of a group of researchers working on furthering medical understanding of this phenomenon.
Ultrashort femtosecond lasers are known for their capacity to efficiently fabricate complex nanostructures and devices for a wide variety of applications. In two recent studies, the properties of femtosecond laser-structured surfaces were revealed thanks to a unique SEM image reconstruction technique.
Scientists from the ISEN (Institut Supérieur de l’Électronique et du Numérique) in Lille, France, used photoelectron spectroscopy to investigate a new method for growing PbS nanoplatelets on InP surfaces.
Bioceramics are particularly useful in the repair and reconstruction of bone. A group of researchers at the University of Limoges investigated the impact of bioceramic surface topography and composition on protein adhesion forces.
Recently, graphene oxide nanostructures have attracted great interest due to their exceptional physicochemical properties for many applications, including flexible electronics and water purification.
The goal of the NanoRef programme, involving multiple partners (LP-Cnam, INM, LPUB, Institut Fresnel, Novasic and LNE), is to develop a roughness standard with a quasi-continuum spatial frequency spectrum and to define the appropriate machining and polishing processes.
LABMEM facility scientists at the Universidad Nacional de San Luis (Argentina) investigated properties of an inorganic compound for use as a solid electrolyte on a high temperature fuel cell (SOFC type).
Researchers at the FEMTO-ST Institute in Besançon, France studied methods for fabricating lithium niobate ridges to be used for the development of programmable microcomponents.
