STEM Viewgraph of a Cross Section

The NWs were placed horizontally on a Si wafer then with the FEI Helios the Pt protection layer was deposited by E-beam and Ion-beam successively. Subsequently a TEM lamellae was prepared in maual mode (bottom left) and then imaged in STEM mode using the same FEI Helios featuring the core GaAs NW with an AlGaAs Shell (dark region in top and bottom right viewgraphs) and a GaAs outer shell. The work has been done by Dr. Jie Tian and Dr. Michael Gao using the ANFF ACT node dual beam FIB Helios.

Silver Clusters - Invisible Worlds

Silver clusters deposited by thermal evaporation onto self-assembled polystyrene nano-spheres (900 nm). Inspect F SEM FEG @ Nanofacility Piemonte INRIM. Self-assembled polystyrene nanospheres are used as masks for thin films and materials nanostructuration on large area. Maybe the subject doesn't match the topics of this year, but surely the title fits.

Atomic Structure of a Family of Amyloid Fibrils

Pictured are the atomic-resolution structures of three amyloid polymorphs against a (falsely coloured) background image of the fibrils taken with a transmission electron microscope. Determining the fibril structures, and defining the major structural elements and interactions contributing to their hierarchical self-assembly, provides insight into the formation of polymorphic amyloid in a range of protein deposition disorders including Alzheimer’s and Parkinson’s diseases.

WAR IN OUR HUMAN TRENCHES

The captions shows the dramatic encounter, in the liver, of our unsung heroes, the immune cells, and an invading parasite, the trypanosome. Each side bears an impressive arsenal of chemical weapons that will define at the end the unset, or not, of the Sleeping Sickness.

Nanoindent of Copper

Nanoindent on deformed copper imaged with channeling contrast. Nanoindentation is a tool to measure the hardness very localised at a low force. Therefore surface defects such as scratches or, as can be seen here, the oxide layer might have an influence on the measurement.

Gallium Phosphide

Pyramidal shape (ice cream like) of a GaP nanocolumn tipped by a spherical ball containing Ga + In metallic liquid. The metallic ball is coverd by a carbon nanomembrane. The structure was grown by the Metallorganic Chemical Vapours Phase Technique. The colors were obtained by mixing the signals of secondary and backscattered electrons. The mixing is performed using the software FEI Company.

Cork

The picture above shows cork structure. It is composed of suberin, a hydrophobic substance that has impermeable, buoyant, elastic, and fire retardant properties. Cork's bubble-form structure and natural fire retardant make it suitable for acoustic and thermal insulation in house walls, floors, ceilings and facades. Cork's elasticity combined with its near-impermeability makes it suitable as a material for bottle stoppers, especially for wine bottles. Cork stoppers represent about 60% of all cork based production.

Inner Quartz Plasma Tube

Particles were found on the wafer surfaces inline after a plasma was generated through this quartz tube. I cracked open the tube and found how the plasma was etching into the quartz, revealing these structures that would eventually thin enough to break off and land on the wafer.
