Coupling electron microscopy techniques with in situ heating ability allows us to study phase transformations on the single-nanoparticle level.
Crack healing induced electrical and mechanical properties recovery in a Ti2SnC ceramic

Publication

Journal of the European Ceramic Society

Li, S.; Bei, G.; Chen, X.; Zhang, L.; Zhou, Y.; Mačković, M.; Spiecker, E.; Greil, P.

Ceramics are able to heal cracks and flaws by triggering local sintering (internal cracks) or oxidation reaction (surface cracks) which may induce the recovery of mechanical strength.
Unravelling structural ambiguities in lithium- and manganese-rich transition metal oxides

Publication

Nature Communications

Shukla, A. K.; Ramasse, Q. M.; Ophus, C.; Duncan, H.; Hage, F.; Chen, G.

Although Li- and Mn-rich transition metal oxides have been extensively studied as high-capacity cathode materials for Li-ion batteries, the crystal structure of these materials in their pristine state is not yet fully understood.
Exploring the single atom spin state by electron spectroscopy

Publication

Physical Review Letters

Lin,Y. -C.; Teng, P. -Y.; Chiu, P, -W.; Suenaga, K.

To control the spin state of an individual atom is an ultimate goal for spintronics. A single atom magnet, which may lead to a supercapacity memory device if realized, requires the high-spin state of an isolated individual atom.
Resonances of nanoparticles with poor plasmonic metal tips

Publication

Scientific Reports

Ringe, E.; DeSantis, C. J.; Collins, S. M.; Duchamp, M.; Dunin-Borkowski, R. E.; Skrabalak, S. E.; Midgley, P. A.

The catalytic and optical properties of metal nanoparticles can be combined to create platforms for light-driven chemical energy storage and enhanced in-situ reaction monitoring. However, the heavily damped plasmon resonances of many catalytically active metals (e.g.

Combined Cr and Mo poisoning of (La,Sr)(Co,Fe)O3 − δ solid oxide fuel cell cathodes at the nanoscale

Publication

Solid State Ionics

Ni, N.; Skinner, S.

Cr poisoning has been identified as a critical issue for solid oxide fuel cell (SOFC) cathodes degradation when metallic alloys are used for intermediate temperature SOFCs.
Multi-scale study of initial tool wear on textured alumina coating, and the effect of inclusions in low alloyed steel

Publication

Tribology International

Bejjani, R.; Collin, M.; Thersleff, T.; Odelros, S.

When turning low alloyed steel with hard inclusions, scores and grooves have been observed in the wear of the alumina coating in CVD coated cutting tools. This study focuses on detailed understanding of flank wear in the textured alumina coating and the relation to the workpiece’s inclusions.
Green one step morphosynthesis of silver nanoparticles and their antibacterial and anticancerous activities

Publication
