An international team of researchers, coordinated by the University of Milan and with the collaboration of the ICMATE Institute, studied how the leaf of the carnivorous plant Drosera Capensis is able to bend when it is stimulated, for example, with a drop of milk. The interdisciplinary approach has combined biophysical studies with structural microscopy of the leaf, quantitative analysis of factors such as auxin involved in cell growth and computer simulations that allowed the creation of a metamaterial that encompasses all biological properties observed in the plant. This study, in addition to allowing the creation of a new metamaterial, led to the understanding of the mechanism used by the leaf to bend over the prey, correlating it to the structural properties of the cells that make up the leaf itself.
News & Events
Marco Musiani, research director at ICMATE CNR Padova, has been appointed Honorary Member of the International Society of Electrochemistry (ISE) by the Executive Committee of the Society, which has approved a proposal of the seven ISE Presidents in charge from 2005 to 2018. ISE Honorary Members are appointed primarily in recognition of their contribution to the Society. The ISE By-Laws limit to ten their maximum number, at any time.
The definition of the authenticity of artworks has undergone a slow process of development: with time, connoisseurship — the traditional practice of attributing detailed artistic identities to works of art on the basis of a comparative analysis of stylistic and formal components — has lost its position of technical leadership. In fact, currently, trust in the expert eye is increasingly subjected to the “objective” outcomes ensured by new and more rigorous techniques of scientific analysis of materials. However, this approach risks being somewhat reductive and incomplete.
THIS WEEK'S HIGHLIGHTS
The electric micro-generation is gaining an increasing interest in the last years both for off-grid systems and for energy harvesting applications. In particular, starting from our skills and expertise in the field of microcombustion, the interest is now moving towards the development of co-generative and energy recovery systems based on Peltier cells.
Alloy design method which consists of theoretical analysis and experimental examination has been /is applied to develop three class of alloy systems, i.e. new Pb-free solders, alloy catalysts and biomedical alloys by using nanoparticles (NPs).
Carbon Glass (CG) and CG modified with Carbon Nanotubes (NTs) or poly-ethylenedioxythiophene (PEDOT) electrodes, for the sensing of chemotherapic molecules in physiological solutions, through Cyclic Voltammetry (CV) and Differential Pulsed Voltammetry (DPV).
