A micro-power energy harvesting system based on core(crystalline Si)-shell(amorphous Si) nanowire solar cells together with a nanowire-modified CMOS sensing platform have been developed to be used in a dust-sized autonomous chemical sensor node. The mote ( ...
Slurries are widely used in important chemical and pharmaceutical manufacturing processes. In this presentation we report chemical monitoring and modeling of batch slurry reactions using optical and calorimetric measurement where key analytes are present i ...
Photo-induced charge separation and charge transport are fundamental processes in many energy conversion techniques, where light is converted into chemical energy (PEC), into electrical energy (solar cells) or in the opposite sense if electrical energy is ...
The morphology of monolayers prepared from ternary lipid mixtures that have coexisting fluid phases has been examined by atomic force microscopy for samples transferred to mica before and after exposure to air. Mixtures of 1,2-dioleoyl- sn-glycero-3-phosph ...
Electronic and magnetic properties of quasi-one dimensional ormore widely low-dimensional systems aswell as their related correlated electron phenomena have been at the very frontier of condensed matter physics for quite some time. The reduced dimensionali ...
A combined synchrotron X-ray diffraction, Raman scattering, and infrared spectroscopy study of the pressure-induced changes in H3BO3 to 10 GPa revealed a new high-pressure phase transition between 1 and 2 GPa followed by chemical decomposition into cubic H ...
We investigated Si nanowires (SiNWs) fabricated by wet etching and chemical vapor deposition (CVD), and core-shell structures, formed by depositing silicon layers around the SiNWs, with respect to their crystallinity, the doping level, and the influence of ...
Recently, hybrid organic-inorganic metal halide perovskites have gained prominence as potent light harvesters in thin film solid-state photovoltaics. In particular the solar-to-electric power conversion efficiency (PCE) of devices using CH3NH3PbI3 as sensi ...
Post-synthesis thermal treatment promotes crystallinity and decrease the defect d. in soln.-processed nanomaterials. In particular, the annealing atm. strongly influences the functional properties of ZnO nanowires (NWs) and specifically their performance a ...
Semiconductor nanowires (NWs) possess a fascinating ability to efficiently collect and trap light into a sub-wavelength volume due to the occurrence of leaky mode resonances. The same confinement ability is manifested by metal nanostructures thanks to the ...
