Interfacial charge sepn. in hybrid solar cells depends on both the energetic alignment and electronic coupling between the inorg. and org. semiconducting materials at the hetero interface. In the present work, bilayer solar cells comprising the small mol. ...
If nanotechnology proves to be successful for bulk applications, large quantities of nanocomposites are likely to end up in municipal solid waste incineration (MSWI) plants. Various studies indicate that nanoobjects might be harmful to human health and the ...
In this work, the tribocorrosion behavior of Ti-12.5Mo, Ti-13Nb-13Zr and Ti-29Nb-13Ta-4.6Zr beta titanium alloys which are candidate biomaterials for joint prostheses is studied against ultra high molecular weight polyethylene in Hank's balanced salt solut ...
The mechanical and electrical properties of nanocomposites created by gold and titanium implantation into Polydimethysiloxane (PDMS) are reported for doses from 1015 at/cm2 to 5x1016 at/cm2, and for ion energies of 2.5 keV, 5 keV and 10 keV. TEM cross-sect ...
In this work, a low-firing thick-film materials system allowing fabrication of piezoresistive sensors on surgical alloys is presented in detail, with application to a force-sensing surgical instrument. The system comprises a series of individual thick-film ...
Titanium oxide due to its optical properties, such as high refractive index, transparency to visible light and photocatalytic properties is being used in a large number of devices such as micro-optical elements and solar cells. The fabrication of TiO2 micr ...
A tetragonal molybdenum nitride (beta-Mo2N) has been prepared by temperature programmed treatment of MoO3 in flowing N-2 + H-2 and for the first time shown to catalyze the liquid phase selective hydrogenation (T = 423 K; P-H2 = 11 bar) of a series of para- ...
Ole-ain't: Trialkyl oxonium salts are universal reagents for native-ligand stripping of carboxylate- (e.g., oleate-), phosphonate-, and amine-passivated nanocrystal thin films and dispersions to give bare or BF 4 -/DMF-passivated surfaces. Meerwein-activat ...
The properties of tasked nanocrystals in energy-related devices are strongly dependent on the presence and chem. nature of ligands at their surface, and the architectures they assume in electroactive layers. Here we will describe an exceptionally versatile ...
