Supramolecular metal ion assemblies are deposited from their solutions onto highly orientated pyrolytic graphite (HOPG) substrates to be imaged by scanning tunnelling microscopy (STM). Since the structural and electronic information of STM measurements are strongly entangled, the spectroscopic interpretation and analysis of the images of such molecular assemblies has proven to be challenging. T...

The shape memory effect exhibited by Fe-Mn-Si based alloys is due to the y(f.c.c.)-e(h.c.p.) martensitic transformation. The martensitic transformation induced by traction at room temperature in a Fe16Mn-9Cr-5Si-4Ni (%mass) is here studied by optical microscopy, scanning electron microscopy, transmission electron microscopy and scanning tunnelling microscopy. The martensitic microstructure and ...

The electropolymerization of 3,4-ethylenedioxythiophene (EDOT) to poly(3,4-ethylenedioxythiophene) (PEDOT) was investigated in the air and water-stable ionic liquids 1-hexyl-3-methylimidazolium tris(pentafluoroethyl) trifluorophosphate [HMIm]FAP and 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl) amide [EMIm]TFSA. In situ scanning tunnelling microscopy (STM) results show that the elect...

Scanning probe microscopy techniques (SPM) have been applied to a rapidly improvement in the characterization of metal oxide nanocrystalline. These materials are widely used in photon-to-electricity conversion devices, such as dye-sensitized solar cells. The surface properties of such nanocrystalline determine the devices’ performance. SPM imaging of nanocrystal surfaces and nanoscale systems h...
