An All-in-One Nanomechanical Bio-nanofluidic System for Possible Applications as Sensor and Actuator in Precise Drug Delivery

Fakhrabadi M.M.S., Università Degli Studi di Padova, IT

The paper presents the physical design and mathematical formulation of a bio-nanofluidic device for possible applications in nanoengineering in general and bio-nanoengineering in particular such as in precise drug delivery as sensors and actuators. The [...]

Enhanced in vitro testing model for rapid risk assessment of ingested nanomaterials

Carnovale C., Guarnieri D., De Angelis I., Barone F., Sabella S., Italian Institute of Technology, IT

Following advances in the synthesis of manufactured nanomaterials, interest for their inclusion in various consumer products has increased. Due to various factors including their unique optical and antimicrobial properties, likely applications of nanomaterials include textiles, [...]

From Self-assembled Brominated Diphenylacetylene Molecules to On-surface Organic Nanowires

Sedona F., Seyyed Fakhrabadi M.M., Sambi M., Università Degli Studi di Padova, IT

Fabrication of nanomaterials is one of the pivotal challenges that researchers endeavor to find novel techniques for them. Due to the inherent and practical limitations of top-down techniques frequently applied to fabricate nanosystems, scientists try [...]

Immobilization of TiO2 nanopowders in multilayer fluorinated coatings for highly efficient clear and turbid wastewater remediation

Diamanti M.V., Bettini L.G., Milani P., Sansotera M., Persico F., Navarrini W., Pedeferri M.P., Politecnico di Milano, IT

The use of nanosized photocatalytic TiO2 in suspension or slurry type reactors is well reported. However, the industrial feasibility of such systems is limited, on account of the low quantum efficiency reported for slurry processes [...]

Improving the optical-radiative properties of TiO2 containing coatings – a side effect of air purification

Paolini R., Sleiman M., Pedeferri M.P., Diamanti M.V., Politecnico di Milano, IT

A manifold positive contribution to climate change mitigation and in the improvement of air quality of built environments can be provided by the use of titanium dioxide (TiO2), also – but not exclusively – as [...]

MaimAir: A Flexible and Modular Energy Storage System for Tomorrow Energy Banks

Fargion D., Habib E., Rome University 1, Sapienza, IT

We considered a novel energy storage system based on the compression of air through pumped water. Differently from CAES on trial, the proposed indirect compression leaves the opportunity to choose the kind of compression from [...]

Perfluoropolyethers as superhydrophobizing agents for carbon-based surfaces of fuel cell gas diffusion layers

Navarrini W., Sansotera M., Diamanti M.V., Pedeferri MP., Gola M., Dotelli G., Politecnico di Milano, IT

Perfluoropolyether (PFPE) peroxide has been employed in the functionalization of conductive carbon-based materials to confer them the highly hydrophobic surface properties of the perfluorinated materials. The thermal decomposition of a linear PFPE peroxide produced PFPE [...]

Hexadecane and water droplets impacting on amphiphobic surfaces

Veronesi F., Raimondo M., Guarini G., Boveri G., Institute of Science and Technology for Ceramics ISTEC CNR, IT

The control of surface wetting and the ability to actively modulate its response in different environments and against different liquids can make a bulk material a new functional one. In the field of materials science, [...]

Allyl, glycidyl methacrylate and cyclodextrin-modified nanocelluloses. Preparation, characterisation and adsorption-release specific properties

Vismara E., Zarattini M., Bernardi A., Nanni D., Bertini S., Freire C., Politecnico di Milano, IT

Advances in the chemical modification of nanocelluloses have been recently reviewed by Youssef Habibi.1 Our work aims to enlarge the number of nanocellulose chemical modifications and broaden the horizon of nanocellulose applications. Oxidized and hydrolyzed [...]

Memristor fabrication and characterization based on TiO2

Diamanti M.V., Pisoni R., Cologni A., Corinto F., Pedeferri M.P., Politecnico di Milano, IT

Today, Si-based flash memory devices represent the most prominent nonvolatile data memory (NVM) because of high density and low fabrication costs. However, they suffer from low endurance, low write speed, and high voltages required for [...]
