The ongoing technological advances necessitate the discovery of new materials with exceptional functional properties to ensure superior efficiency, stability, and cost effectiveness. [1-4] The available options are inadequate as long as the search is limited to the stable ground states of materials. Alternatively, the oft-overlooked arena of ‘metastable’phases promises us with limitless new possibilities.
ART-ER promuove e supporta l’accesso di ricercatori e imprese con sede in Emilia-Romagna alle opportunità di finanziamento per ricerca e innovazione dell'Unione Europea. In particolare, ART-ER svolge il ruolo di punto di contatto regionale per i finanziamenti sia in qualità di Sportello APRE Emilia-Romagna (dal 2004) sia come nodo locale della Enterprise Europe Network (dalla sua nascita nel 2008).
Electrodeposition is one of the main thin films deposition technique in the laboratory of materials and renewable energies (LMER) on the faculty of sciences Ibn Zohr of Agadir_Morocco. Among the compound that are already elaborated, ZnO, Cu2ZnSnS4, Cu2O, In2O3, CuInS2 and very recently CuSbSe2.
The seminar will be focused on the results obtained so far on the different electrodeposition techniques used to develop CuSbSe2 thin films, as well as some characterization results such as XRD, SEM and UV-Vis spectrophotometry.
Nel seminario saranno illustrate le caratteristiche del sistema SEM-FIB Zeiss Auriga Compact dell'Istituto IMEM-CNR. Sulla base di esempi di attività svolte negli ultimi anni in Istituto, saranno mostrate le attuali potenzialità dello strumento in diverse modalità: SEM (microscopia elettronica), EDX (analisi composizionale), GIS (deposizione di metalli) e FIB (microscopia, incisione e impiantazione a fascio ionico). Saranno inoltre elencati alcuni possibili sviluppi del sistema in grado di ampliarne le attuali potenzialità e soddisfare le esigenze di nuove attività di ricerca.
Nanotechnology has enabled unprecedented control of the interactions between materials and biological
entities, from the microscale down to the molecular level. For example, nanosurfaces and nanostructures
have been used to mimic or interact with biological microenvironments, to support specific biological
functions such as cell adhesion, mobility and differentiation, as well as tissue healing.
Recently, a new paradigm has been proposed for nanomedicine to exploit the intrinsic properties of
In this seminar, metal-matrix (tungsten-based) and ceramic (strontium ferrite-based) composites will be presented. Tungsten-based composites, which will be presented, are candidates for the DEMO divertor. DEMO is a next generation of fusion reactors, which will also be a demonstrational fusion power plant and the divertor is part of the reactor chamber, which has to withstand the highest thermal loads. On the other hand, strontium ferrite-based composites are part of the quest to replace rare-earth magnets in applications, which do not require such high energy products (BHmax).
The ESRF Detector Unit has a long experience in the development of X-ray detectors for a wide range of synchrotron applications. After a brief introduction of the ESRF, this talk will present examples of in-house designed 2D detector systems and their applications on beamlines, with some insights into the underlying technologies.
Resistive switching in nano particle incorporated polymer and bio degradable films is now a fast growing field as it has memory applications. Further the conduction mechanisms involved that lead to switching are of great interest.
Giving a brief summary of the status of different emerging memory sytems, I shall describe our work and recent results on resistive switching in :
1. PMMA-Al doped ZnO nano particles,
2. PVA-reduced graphene oxide
3. Gelatin-Graphene Oxide,
4. Gelatin-CdTe quantum dots and
5. Gelatin-Silver nano particles.
Low field microwave absorption (LFMA) was first observed in Cuprate high-Tc Superconductors. Later LFMA was reported in half metallic manganites, then followed by some magnetic materials. The fact that LFMA is not observable in every magnetic material makes this phenomenon intriguing. Examples for LFMA in ZnO system arre given, then LFMA in multiferroic BiFO3 sytem is described. We then show our preliminary results from BiFe0.5Mn0.5O3 system from Parma.
The remaining part of my talk is about a brief description of other activities of my group at UNISA:
