Description of the Research Group

The research group belongs to Fundamental for Chemical Technologies Sector, acting in Brescia on three Departments (namely, DRIMI, DII and DMMT). The scientific and teaching activities are devoted to the chemical and chemical-physical foundations in the various technological fields, with particular reference to the materials, their properties and their interaction with the environment, providing a synthesis of the principles common to different phenomena and the different substance categories. Its content is suitable for teaching subjects specific to the sector both to the basic courses and to the more advanced disciplines with a high degree of complexity.

Research Activities
  • Material characterization

To enhance the understanding of materials properties and behavior is the primary aim of Chem4Tech. In particular, the activities are focused to develop and to optimize experimental techniques, methods, and protocols for studying new materials/devices.

Researches cover a very wide variety of materials (metal, ceramic, glass, semiconductor, polymers, and bio-organic materials) and they are carried out in collaboration with several national and international researchers belonging to government as well as private research laboratories.

Several facilities are available at Chem4Tech for physical, chemical, functional, and mechanical characterization of materials.

 

  • Eco-materials

Materials that have the least impact during the life cycle, also maintaining high quality and reliability performances, are defined as eco-materials. In the future, eco-materials will play an mandatory role in the development of the technologies, because of the need to minimize environmental impact, improve recyclability, and increase its energy and efficiency.

Our research objectives in this area are:

- to reduce the use of non-renewable resources; -

- to replace of non-renewable resources with renewable sources

- to reduce the use of natural resources

- to increase the use of recycled resources.

 

  • Atomic Layer Deposition

The ALD is a thin-film deposition method in which a film is grown on a substrate exposing the surface to gaseous species. Unlike chemical vapor deposition, the precursors are not present simultaneously in the reactor, but are inserted as a series of sequential pulses. In this way, the precursor molecules react with the surface in a self-limiting way and, consequently, the ALD cycle is determined by the nature of the precursor-surface interaction. The depositions are uniform and high accuracy can be achieved on arbitrarily complex and large substrates.

ALD is an active research field in our research group and several deposition processes have already been developed.

 

  • SIRIMAP project

The SIRIMAP project aims to develop new remote and proximity detection systems to monitor marine pollution due to macro, meso and microplastics, methodologies for their in-situ and at lab scale analyses, and appropriate strategies for recovery and recycling.

The objectives of SIRIMAP are particularly relevant for the protection of the Mediterranean Sea, recently identified as a great accumulation region of plastic debris. In this scenario, SIRIMAP represents a strategic proposal for the "Blue Growth" topic, in agreement with international, European and National guidelines.

The objectives of the project are: development of satellite data analysis methodologies and strategies for remote mapping of macroplastics, development of detection platform (drone) for proximity mapping of meso/microplastics; sampling and in-situ analyses, characterization of meso-microplastics and recovery/recycling strategy assessment; experimental development and demonstrators. The expected results are the development, design and implementation of: new algorithms for detecting plastics using satellite data; a new flying configuration with detachable and recoverable payload, a new hyperspectral analysis for mapping by drone; innovative methodologies for in situ analysis through a microfluidic system and an innovative microplastic analysis system. The obtained results will allow the realization of high-level demonstrators such as: a mock at real-scale with payload, a compact opto/mechanical system for in-situ analysis, innovative plant solutions for waste separation; prototyping of composites.
