Abstract: A process for the synthesis of nanocrystals of metal chalcohalides is disclosed, where M is a metal, E is a chalcogen and X is a halogen, starting from a salt of M. The process includes the following steps: a) a precursor of metal M is mixed with a surfactant in a solvent having a boiling point higher than 180° C.; b) the mixture obtained in previous step a) is heated, in order to dissolve the components, until it becomes clear; c) the solution is heated up under inert atmosphere at the desired temperature; d) chalcogen and halogen precursors in 0 a solvent having a boiling point higher than 180° C. are added through injection, while heating the solution obtained in steps a) to c); e) after the reaction time has elapsed, the product is quenched down to room temperature.

The invention also relates to a process for the preparation of titanium dioxide nanorods with anatase phase composition, which are highly suitable for applications involving photovoltaic cells, particularly Dye Sensitized Solar Cells (DSSC), photoelectrolysis cells and tandem cells for the conversion of solar energy and the production of hydrogen.

Abstract: An organic light emitting diode (OLED) emitting light downward through a transparent substrate. The OLED embeds a microcavity formed between a cathode and an anode and includes a plurality of organic layers including a light emitting layer. The plurality of organic layers include at least a first layer made of an organic doped material aimed at enhancing the transport of electrons; and at least a second layer made of an organic doped material aimed at enhancing the transport of holes. The anode is obtained by deposition of a semitransparent layer of silver (Ag) over the transparent substrate to be directly in contact with the first doped organic layer. Then, thicknesses of the first and second doped organic layers can be freely adapted to best adjust the optical characteristics of the microcavity for the wavelength of monochromatic light to be produced by the OLED.

Abstract: The present invention relates to a double layer coating formed of a first layer (lower layer) of photo/thermosetting resin and a second later (upper layer) comprising hydrophobic microparticles partially incorporated in a matrix of photo/thermosetting resin. The application of said coating is an effective method for generating ultra water-repellent and antireflective surfaces.

Abstract: Masters for imprint processes are produced by providing a resist layer, and patterning the resist layer after a respective mold pattern to produce a patterned resist layer adapted to be directly used as a master for imprint lithography. Preferably the resist is spin cast on a substrate and is comprised of a photoresist, such as negative-tone, electron-beam sensitive resist having a glass transition temperature above 200° C. and adapted to be mechanically stable to pressures up to 104 psi. Preferably, the resist is a polymer resist, such as an epoxy resist e.g. SU8 and SU8-2000. Patterning the resist layer includes the steps of structuring the resist layer, soft-baking the structured resist layer in order to selectively cross-link the structured portion of the structured resist layer and developing the structured resist layer in order to receive a patterned resist layer. The patterned resist layer is preferably cured e.g.
