Nanocellulose providing sustainable solutions for the needs of industry

15.02.2012 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.

Compressing the surface of softened solid wood improves its properties in an environmentally friendly way

17.02.2012 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 units can be planned more accurately with new models

07.03.2012 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.

To get Finns excited about electric cars, we first need batteries

02.04.2012 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.

Paper structure affects the number of breaks in paper machines

17.04.2012 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.

From packaging into an experience

27.04.2012 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.

Creating packaging experiences

23.05.2012 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.

Computational models mean more efficient industrial processes

29.05.2012 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.

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.

Better composite materials using graphene

13.08.2012 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.

Nanocellulose enables the manufacturing of new environmentally friendly materials

03.10.2012 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.

Virtual experiments on viruses

05.11.2012 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.
