Bio/Nanotechnology

Understanding the behaviour of water and nanofluids
Nanoscience and nanotechnology are undergoing rapid exponential growth. According to this new way of looking at how manipulate and utilize matter on a very small scale, our vision is to explore the potentialities of nanotechnologies when meet medicine. In this context, computer modeling of nanoscale matter will be the bridge from theoretical findings to nanomedicine applications: For example, from magnetic nanoproperties of iron to innovative cancer treatments.

Micro/Nanotechnology

Enhancing heat transfer for electronics cooling
Micro/Nanotechnology has a tremendous potential for solving long-lasting problems in engineering. However, most of the times, nano-technological ideas do not go beyond proof-of-concept. We work in strong connection with micro/nanotechnology experts for boosting nano-technological ideas up to industrialization.

Energy

Future emerging technologies and fuel cells
Energy sector is crucial for society. Future emerging technologies are required for fulfilling the increasing demand for energy, in a respectful way with regards to environment. We study new materials for promoting thermal conduction, functionalized surfaces for enhancing heat transfer and nano-engineered porous electrodes for next-generation fuel cells.

Modelling & Simulation

Lattice Boltzmann model and systematic model reduction
Modeling and simulations are essential in modern science and engineering. However we think that they cannot be unrelated to applications. Hence our laboratory develops innovative computational methods in order to make feasible the investigation of new phenomena. The most important results are in the context of the Lattice Boltzmann method and systematic model reduction of complex models.

The transport of water in nanoconfined geometries is different from bulk phase and has tremendous implications in nanotechnology and biotechnology. In the recent paper published by Elio Chiavazzo, Matteo Fasano and Pietro Asinari on NATURE Communications, the molecular dynamics is used to compute the self-diffusion coefficient D of water within nanopores, around nanoparticles, carbon nanotubes and proteins. For almost 60 different cases, D is found to scale linearly with a parameter which represents the ratio between the confined and total water volumes. As an example, such relationship is shown to accurately predict the relaxometric response of contrast agents for magnetic resonance imaging. This relationship can help in interpreting the transport of water molecules under nanoconfined conditions and tailoring nanostructures with precise modulation of water mobility. More

In the recent paper published by Luigi Ventola, Eliodoro Chiavazzo and Pietro Asinari on Int. J. of Heat and Mass Transfer, experimental evidences are reported on the potential of direct metal laser sintering (DMLS) in manufacturing at and finned heat sinks with a remarkably enhanced convective heat transfer coefficient, taking advantage of artificial roughness in fully turbulent regime. To the best of our knowledge, this is the first study where artificial roughness by DMLS is investigated in terms of such thermal performances. On rough at surfaces, we experience a peak of 73% for the convective heat transfer enhancement (63% on average) compared to smooth surfaces. We propose that heat transfer close to the wall is dominated by eddies with size depending on the roughness dimensions and the viscous (Kolmogorov) length scale. More

In the recent paper published by Eliodoro Chiavazzo, Luigi Ventola and Pietro Asinari on Experimental Thermal and Fluid Science, a sensor for measuring small convective heat flows (<0.2 W/cm^2) from micro-structured surfaces is designed and tested. This sensor exploits the notion of thermal guard and is purposely designed to deal with metal samples made by additive manufacturing, such as direct metal laser sintering (DMLS). Similar works in the literature often have the necessity of maintaining one-directional heat flows along the main dimension of a conducting bar using insulating materials. Such an approach can be critical for small fluxes due to the curse of heat conduction losses along secondary directions. As a result, it is necessary to estimate those secondary fluxes (e.g. by numerical models), thus making the measurement difficult and indirect. On the other hand, depending on the manufacturing accuracy, the present sensor enables to practically reduce at will those losses, with direct measurement of the heat flux. More
