:Recycling and depolluting are some of the biggest tasks of our society in the current time. For this purpose, finding greener processes for ionic or molecular extraction, based on liquid-liquid phase separation, is one of the very challenging problems faced to material scientists. In this aim, thermomorphic Aqueous Biphasic Systems (ABS) have been explored and....

From planktonic species (a few micrometers in size) to large mammals (up to several meters), the movements of aquatic organisms span a wide range of length and time scales. Their individual and collective movements as well as their intra- and interspecific mutual interactions have significant ecological and environmental impacts [Pavlov & Kasumyan 2000]. Several social....

Gaining a better understanding of the mechanical behaviour of snow is crucial for numerous applications, including avalanche forecasting and risk management, modelling the evolution of seasonal snowpack and polar firn, and predicting the loads induced by the snowpack on infrastructure and buildings. Snow is a complex material characterised by a highly porous microstructure and a....

: Growing roots of plants constitute typical cases of living organisms able to forage the soil by adapting to the environment, avoiding obstacles, and following some attractors as gravity, water or nutrient gradients. Beyond the scientific challenge to understand, characterize, and reproduce strategies of living organisms to penetrate and move into the soil, growing roots....

Buildings use about 40% of Europe’s total energy, with more than half dedicated to heating and cooling. Insulation is key to reducing energy demand, but most current materials, such as glass wool, rock wool, and polymer foams, are derived from non-renewable sources and are hard to recycle. Bio-based alternatives made from plant, animal, or mineral....

Bacteria spend most of their life attached to surfaces, in structured colonies encased in a self-produced polymeric matrix called biofilms, which are the prevalent form of life on earth. The organization in biofilms confers them a selective advantage over the individual, e.g., by increasing resistance to mechanical damage and antibiotic agents. This strongly influences the....

The fabrication of 3D objects embedding electronic functionalities is a rather new research area which relies on the combined development of: i) new manufacturing machines and control strategies, ii) new materials with adapted rheology and functionalities, ii) the design and simulation of new 3D devices with unconventional geometries. Despite the intrinsic complexity of direct devices....
