A Multiscale investigation of the influence of surface morphology on thin films CVD deposition

Barbato A., Rondanini M., Cavallotti C., Politecnico di Milano, IT

Growth rates and morphology of thin solid films deposited through Chemical Vapor Deposition processes are strongly dependent on chemical-physical events that occur at time and length scales differing by several orders of magnitudes. Models adopted [...]

A Kinetic Study of the MOCVD of GaN

Moscatelli D., Cavallotti C., Politecnico di Milano, IT

Quantum chemistry investigations have been performed to study the gas phase chemistry active during the MOVPE of GaN when Ga(CH3)3 and NH3, diluted in a H2 carrier gas, are used as precursors. Optimized molecular geometries, [...]

Molecular Dynamic investigation of the interaction of supported affinity ligands with Monoclonal Antibodies

Zamolo L., Busini V., Moiani D., Moscatelli D., Cavallotti C., Politecnico di Milano, IT

Monoclonal antibodies are gaining an increasing importance in diagnostic and therapeutic treatment of grave diseases such as immunodeficiency, Alzheimer’s syndrome and cancer. The production of these pharmaceuticals and especially the purification step, however, are still [...]

Influence of His-195 on the nitrogenase FeMo-cofactor activity

Cavallotti C., Moscatelli D., Carrà S., Politecnico di Milano, IT

Mo-nitrogenase is the enzyme responsible for the conversion of atmospheric nitrogen to ammonia. Its active site is the iron-molibdenum cofactor, FeMo-co, which is composed by two incomplete cubes, Fe4S3 and MoFe3S3, connected through three bridging [...]

Batch Fabrication of Nanostructured Heterogeneous Microarrays for Chemical Sensing

Barborini E., Leccardi M., Bertolini G., Rorato O., Repetto P., Bandiera D., Gatelli M., Raso A., Garibbo A., Seminara L., Ducati C., Milani P., Tethis srl, IT

Deposition of nanoparticles from the gas phase is becoming an enabling technology for batch production of nanostructured devices. Supersonic clusters beam deposition (SCBD) has been shown as a viable route for the production of nanostructured [...]

Low-T Quantum Transport in Carbon Nanotubes: Role of Vacuum Fluctuations in Loss of Phase Coherence

Gabrielli P.G., Gabrielli S., Gabrielli P.G., Gabrielli S., ENEA, IT

Among the items in the design of new generation of electronic devices there are the measurement and understanding of the current-voltage response of an electronic circuit in which molecular systems like carbon nanotubes (CNTs) act [...]

Growth of Ge nanowires by chemical vapour deposition technique

Phani A.R., Grossi V., Passacantando M., Ottaviano L., Santucci S., National Institute of Nuclear Physic, IT

Germanium, Mn doped Ge nanowires have been synthesized using chemical vapor deposition with Au nanoparticles (with size ranging from 5nm to 10 nm) as nucleating centers (catalysts) and Germanium, Manganese powders as a source for [...]

Study of field emission of multiwalled C nanotubes from arc discharge

Bellucci S., Balasubramanian C., Giannini G., Marchetti M., Micciulla F., Regi M., INFN-Laboratori Nazionali di Frascati, IT

Carbon nanotubes (CNT) were synthesized by DC thermal plasma method. After optimizing the synthesis parameters like the pressure, current etc., the synthesized products especially the anodic deposit was characterized by electron microscopies like Scanning Electron [...]

High performance iPP based nanocomposite for food packaging application

Avella M., Errico M.E., Gentile G., INSTITUTE OF POLYMER CHEMISTRY AND TECHNOLOGY - CNR, IT

High performance iPP based nanocomposites filled with innovative calcium carbonate nanoparticles were prepared by melt mixing. Peculiarities of the nanoparticles were the high specific surface area, the elongated shape (aragonite), and the surface modifiers (polypropylene-maleic [...]
