Cellulose is an important naturally occurring polymer, which humans have utilized for millennia. Today, researchers are chopping cellulose fibres into nanoforms and looking for solutions for industry's sustainable material needs.
M.Sc. (Tech.) Lauri Rautkari has developed several methods that can be used to improve the properties of for example Finnish tree species, Norway spruce and Scots pine, for the purposes of industrial use. The ecological and inexpensive methods can be compared to mangling or ironing using a steam iron. Compressing the surface of solid wood, such as floor planks, has similar effects as pressing sheets with a mangle.
Carbon capture and storage is a possible solution in reducing carbon dioxide emissions: for example when carbon dioxide is captured from flue gases emitted from power plants it does not go into the atmosphere. In her doctoral dissertation Claudia Dell’Era, M.Sc., from Aalto University's School of Chemical Technology performed phase equilibrium measurements and developed models which can be exploited in the design of separation processes for carbon dioxide removal.
Electric cars will only be driving around city streets in Finland after powerful enough batteries have been developed for them. The batteries must be compatible with future charging networks and the cold climate of Finland. Researchers from Aalto University are seeking a solution to the problem and analysing lithium-ion batteries with the aim to find a model suitable for the conditions in Finland.
In paper machines, breaks always mean financial losses. The better the runnability of a paper machine, the fewer the breaks that occur. Master of Science (Tech.) Markku Ora's doctoral dissertation revealed that the structure of paper affects the runnability of a paper machine. Ora will defend his doctoral dissertation at Aalto University this week.
Since 2007, the Department of Biotechnology and Chemical Technology and Neste Oil have been developing a new oil production method. The microbial oil research project has now reached the point where a pilot plant is being built in Porvoo.
Quality wine can turn to vinegar when gulped down from a plastic cup and cheap plonk sipped from a wine glass by the Eiffel Tower may seem like the most palate-pleasing experience you have ever had.
A product’s packaging is not merely a protective shell it travels home from the store in. Packaging may be fun and beautiful and does not need to be taken seriously.
Optimisation of industrial processes requires the ability to understand and predict the phenomena occurring during the actual processes. Computational models make it easier to understand the physical and chemical phenomena occurring between bubbles, particles and droplets – particularly when substances appear in the processes in several different states.
Professors Sami Franssila and Kyösti Kontturi, Visiting Professor Roman Nowak, Teacher-Researcher Lasse Murtomäki and Academy Research Fellow Maria Sammalkorpi have received research funding of a significant amount from the Academy of Finland in the Programmable Material Research Programme application process.

The IMPRESS Integrated Project, which focused on the study of intermetallic compounds, has been selected as one of the ten best EU-funded projects in industrial technologies. The EU funds over 900 such projects. Professor Michael Gasik from the School of Chemical Technology and his team of researchers have added Aalto University’s expertise in materials research to IMPRESS’s vast cooperation network.
During the last few decades, a large number of novel materials have been produced, enabling the development of new products and the improvement of the properties of old ones. This development shows no signs of slowing down. Composite materials are produced by combining two or more materials to get a composite with desired properties.
Graphene, a one-atom-thick lattice structure formed by carbon molecules is the thinnest possible material, and its discovery in 2004 brought the Nobel Prize in Physics for 2010 to Andre Geim and Konstantin Novoselov. The studies on graphene have multiplied exponentially, one sub-field being the use of graphene as a composite material. This research is also being carried out at the Aalto University Department of Biotechnology and Chemical Technology.
The Aalto University schools of technology celebrate their 22nd ceremonial conferment of doctoral degrees on 12 October 2012. Registration will be open until 9 September 2012.
This week, 161 new Finnish students are beginning their studies at the School of Chemical Technology. In addition, the school has today welcomed about 70 foreign students to the Aalto community. Foreign students have come to the school as exchange students (about 40) or as degree students to attend the school’s master’s and Erasmus Mundus programmes.
Aalto University and VTT Technical Research Centre of Finland organised a seminar on bioeconomy in Dipoli Congress Centre on 7 September. The focus of the seminar was on outlining the significance and different sectors of bioeconomy and on finding research topics that would allow Aalto University and VTT to join forces in a concrete way. The goal is to weld together the shared know-how of Aalto University and VTT, making Otaniemi the powerhouse of the bioeconomy development.
Aalto University School of Chemical Technology is part of the new Erasmus Mundus Joint Doctoral Programme, which is funded by the European Commission. The programme is unique among Finnish universities.
Former students from the School of Chemical Technology get together often, even though it's been decades since their studies began. Class reunions bring together old student friends and reinforce alumni connections with the university. For the school and departments, these reunions represent an opportunity to present current themes in research and teaching to an interested group of listeners.
One of the topics studied currently at the Department of Forest Products Technology of the School of Chemical Technology is the use of nanocellulose as reinforcement of polymers such as thermo-plastics. Nanocellulose, or wood fibre broken down to the nanoscale, mixed with a polymer results in a tough material. This purely natural product may replace synthetic petroleum-based fibres commonly used to reinforce composite materials nowadays.
The Aalto University schools of technology will celebrate their joint Ceremonial Conferment of Doctoral Degrees in Otaniemi on 12 October 2012. The doctors and honorary doctors to be conferred will be accepted as members of the technical science community. Doctoral hats will be set on their heads.
A bio-apartment building in Otaniemi, a modifiable sports and recreation centre in Tapiola and a route for light traffic on the nearby shoreline - all of these made from wood. These construction proposals came about from a joint venture between Aalto University students and six organisations, the purpose and aim of which was to come up with ways in which modern Finnish timber construction and the entire wood industry could be promoted.
Zoltán Javór, a doctoral candidate at the School of Chemical Technology has been granted an award at the largest international congress in the field of mineral processing. Mr Javór was awarded the young author award for his presentation. The congress was organised in India in late September. More than 600 works in the field of mineral processing were presented, of which ten received awards.
In his dissertation to be defended at Aalto University, Mikko Mäkelä, M. Sc. (Tech.), examined the use of by-products from forest and steel industries as soil amendments. Mixtures containing, e.g., slag from the steel industry and ashes and sludge from the forest industry proved to be promising new soil amendments compared to contemporary commercial options.
In his dissertation, Samuli Räsänen, PhD (Tech) replaced existing elements with others in well-known functional oxide materials, successfully making these more resistant to heat and moisture. The new materials could be suited for use in batteries, catalysers and power plants.
Minna Annala, M.Sc. (Tech.), publicly defending her doctoral dissertation at Aalto University's School of Chemical Technology, prepared in her thesis work three different electrically conductive plastic materials, which are also mechanically strong. Plastic, which is a known insulator, was, with the help of various polymerization techniques and carbon nanotubes, transformed into an electrically conductive form.
Laboratory work is an essential part of the studies of any chemistry student. However, there are many things that cannot be done due to the limitations posed by existing facilities or equipment. These include experiments conducted on living viruses in biotechnology, as the risk of contamination for people and facilities would be too great. In a virtual laboratory, however, this and many other things are fully possible.
Researchers at Aalto University School of Chemical Technology have developed a method for producing lithium batteries that is cheaper and more environmentally friendly than previously used methods. This new process has succeeded in replacing the harmful methylpyrrolidone (NMP) solvent, which is traditionally used in the manufacturing of electrodes, with water.
The Academy of Finland has decided on the funding for research within the Strategic Centres for Science, Technology and Innovation. At the School of Chemical Technology the funding is granted to two research projects lead by Professor Janne Laine and Professor Markus Linder. The research in both of the projects focuses on nanocellulose and the funding totals ca. 1.2 million euros.
Researchers at Aalto University have developed a simple method for reducing the amount of phosphorus in the wastewater of a pulp mill. The method is called simultaneous precipitation using iron sulphate. A separate treatment stage is not required, as the precipitation takes place simultaneously with the actual biological wastewater treatment.
In his dissertation for Aalto University and the University of Oulu, Mika Pietilä, M.Sc., discovered new properties in stem cells. He studied human mesenchymal stem cells, or MSCs, and found analysis of their metabolism to be helpful in their identification.
