How to talk with nano things: the Micro for Nano approach
No full textThe nano or low-dimensional material is the key and in the meantime the start of a path that must conduct to the final product. The presented Micro4Nano (M4N) architecture was conceived with this path in mind, thinking that the information from the nano/low dimensions can be extracted with a distributed sensor array on chip, that reads electrical parameters in various locations directly from the device surface, where for example arrays of nanostructured materials are grown. The use of an on-die array sensor has several advantages: the direct growth of the nanomaterial on device surface permits the minimization of the stray capacitance as well as the noise issues it is related to; it improves the macrometric inspection of the material, that usually is clustered and not homogeneous at its first realization phase; enables a flexible and robust test-bed for electrical properties inspection on nanodevices, suitable for most of the available and new emerging nanostructured materials

A Comprehensive Review on Hydrogen Production from Biomass Gasification
Full text linkHydrogen production from biomass gasification has emerged as a strategic pathway for achieving carbon-neutral energy systems, circular resource utilization, and sustainable fuel generation. As global energy systems transition toward renewable sources, biomass-derived hydrogen represents a cornerstone of waste valorization, negative-emission bioenergy, and green hydrogen economies. Among all technologies, hydrogen production through gasification is one of the most consolidated routes with plenty of operative industrial-scale plants. The field of gasification is quite complex, and this comprehensive review describes the current scientific and technological achievements of biomass gasification for hydrogen production, describing the effect of feedstock, reactivity phenomena, reactor design, and catalyst systems. Furthermore, we report on a quantitative analysis regarding the operative cost of gasification of biomass compared with green hydrogen production and methane reforming. We provide a complete and synthetic picture for one of the most critical fields in the hydrogen economy that can actively promote a transition towards a more sustainable society
A new method for evaluation of sp3/sp2 ratio in diamond-like films from optical measurements
No full textA new method based on the analysis of the dielectric constant in the energy range 1 – 6.2 eV for the evaluation of sp3/sp2 ratio in a-C and a-C:H films has been proposed. The method has been tested on a number of films deposited by different techniques and it has been compared with the results on sp3/sp2 ratio obtained by other technique
