CATALD: ALD catalytic materials in exhaust pollution reduction and control systems

New business opportunities for sustainable technologies

This project aims to develop the business opportunities and create new business in the field of emission (SOx, NOx, PM) detection, control and reduction from combustion reactions by catalysts. Project will evaluate the potential markets and clarify the state-of-the-art catalyst technologies and improvements needed based on targeted emission limits. Technological development in the project will be based on utilization and investigation of existing and well known atomic layer deposition (ALD) processes of catalytic materials and the evaluation of their commercial exploitation in the exhaust emission reduction applications.

The industrial emission reduction technologies are based on catalysts. The catalytically active materials are deposited on the catalyst support typically by a washcoat method. A washcoat is a carrier for the catalytic and catalytically active materials and is used to disperse the materials over a high surface area. Favorable for the effective performance of catalyst is to maximize the catalytically active surface available to react with the exhaust gas. The catalytic coatings typically have surface roughness of several or several tens of microns. ALD as a surface drive coating method is seen to have a great potential in catalyst surface optimization since it coats conformally the complex shapes of structures and thus maximizes the surface area to be coated.

The primary target for this technology is the manufacturers of system manufacturers for exhaust emission (SOx, NOx and PM) control and reduction in combustion engines.

The project is run by LUT Savo ASTRaL laboratory together with LUT TBRC (Technology Business Research Center).

Roll-to-roll atomic layer deposition development

Atomic layer deposition (ALD) is a process of thin film deposition characterised by extreme uniformity, controllability and conformality. ALD is applied to many areas including microelectronics, photovoltaics and electro-optical displays. Up until now, atomic layer deposition (ALD) has been restricted to batch processing of individual parts. For low cost manufacture of flexible devices, a roll-to-roll process is needed which can deposit on continuous webs. ASTRaL has developed a true roll-to-roll atomic layer deposition (ALD) process aimed towards producing materials for flexible electronics and intelligent packaging applications. It allows us to deposit ALD layers on flexible webs up to 500 mm width.

This project is funded by TEKES/ERDF and our partners are VTT and Tampere University of Technology with support from Stora-Enso, UPM-Raflatac and Innovia films. Details of the roll-to-roll ALD system can be found here.

NANOMEND: Nanoscale Defect Detection Cleaning and Repair for Large Area Substrates

NanoMend is a collaborative, end user led project aimed at pioneering novel technologies for in-line detection, cleaning and repair of micro and nano scale defects on thin films deposited on large area substrates. The aim is to integrate these technologies into systems that work at speeds required for continuous production, thus enabling the new technologies to improve product yield and performance, while keeping manufacturing costs low.


This is an EU Framework 7 project with 14 partners from Finland, Germany, Switzerland, the Netherlands and the United Kingdom. It runs from 2012 to 2015.

PlasTEP: Dissemination and fostering of plasma based technological innovation for environment protection in the Baltic Sea region.

Pollution control is a transnational problem for all countries and a strategic aim of the European Union. This is reflected in the increasing tightening of the exhaust emission standards particularly in the Baltic Sea region (BSR) countries. The objective of the project is to direct plasma based cleaning technologies for atmospheric air and water treatment towards practical application.

This is an EU-funded project under the Baltic Sea Region programme. There are 15 partners from the countries bordering the Baltic Sea. ASTRaL also received support from the Finnish Ministry of the Environment and Miktech Oy. It ran from 2010 to 2012

Bacteriosafe: Active wound dressings based on biological mimicry.

The aim of  BacterioSafe to construct, test and develop a unique active wound dressing, which incorporates novel colourimetric sensor and active therapeutic processes for detecting and counteracting pathogenic bacteria in wounds. The inspiration of this project is the natural mechanism of bacterial attack of healthy cells. The outer cell walls are ruptured by an array of protein toxins, lipases and other enzymes secreted by these bacteria. We mimic this natural process by using these pathogenic factors to liberate engineered and biologically derived antibiotics/antimicrobials and indicating molecules from highly designed surface immobilized nanocapsules. These are immobilised on currently available wound dressing materials such as polypropylene or polyethylene non-wovens using a range of deposition processes. This will minimize the need for frequent traumatic changes of wound dressing and will provide a simple optical indicator of bacterial infection.

This is an EU Framwork 7 project with 11 partners from Australia, Belgium, Finland, Germany, Ireland and the United Kingdom. it runs from 2010 to 2014.
