Bio4Energy Graduate School Opening Conference – Skellefteå, Sweden, 19-20 March 2013
The Bio4Energy Graduate School will officially begin its works on 19-20 March 2013 with a grand opening conference to be held in Skellefteå. On Day 1, from 10.00 to lunch, keynote lectures will be given by well-known guest speakers, while presentations given by PhD students and post-doctorate student will take up the rest of Day 1 and all of Day 2. PhD students and PostDocs are encouraged to submit their abstracts. The best one will be awarded a Solander prize.
The conference is dedicated in particular to PhD students and PostDocs, who will not pay a fee to attend the conference. This is an opportunity for them to present their research, exchange ideas and knowledge and enhance their own networks. Industrial partners and PhD student supervisors are welcome to attend, but will be charged a fee. The conference will be given annually, and participation in at least two of these conferences will be required for graduation. More information about the conference and abstract submission will be sent out after the Christmas vacation, but in the meanwhile book your calendars!

Umeå Renewable Energy Meeting, Umeå, Sweden, 25-27 February 2013
The Chemical Biological Centre (KBC) at Umeå University play host to this meeting which has sessions dedicated to the kind of research that Bio4Energy conducts.
The KBC homepage says: "The meeting aims to strengthen and display our efforts towards research in the renewable energy field that is carried out within several strong research environments and research programmes at Umeå University and the Swedish University of Agricultural Sciences: Solar
Fuels, Artificial Leaf Project, Bio4Energy, BioImprove and Trees and Crops for the Future".PhD students who participate with a poster receive 1 ECTS certificate from the KBC Research School, the announcement says.
The Organising Committee is made up of Bio4Energy members Johannes Messinger, Leif Jönsson, Johannes Hanson, Hannele Tuominen and Per Gardeström. Göran Samuelsson is also part of the committee.

Creating a Bio4Energy Graduate School, Skellefteå, Sweden, 21 November 2012
Ulrika Rova of Bio4Energy has been putting together a working group which is to "make concrete plans to implement the entire research school with workshops and courses". To get started she would like for the working group to meet at Skellefteå where discussions will centre around "the coming steps". To join the meeting as a member of the working group, please fill in the doodle that she sent: http://doodle.com/yf7crk5nym2zpcrc.

Workshop on Gasification Modelling, Luleå, Sweden, 21 November 2012
The Swedish Centre for Biomass Gasification (SFC) consists of three research nodes that focuses on three different gasification principles. Regardless of gasification principle there are certain aspects of the conversion of fuel particles and gas phase reactions that are the same. However, each gasification principle presents a unique set of challenges for the modelling researcher. This workshop is intended to bring together specialists and engineers with an interest in modelling and to create an environment for the sharing knowledge that hopefully will speed up the development of gasification models. The workshop has two parts, the first focusing on the microscopic details of fuel conversion and the gas phase reactions (sub models). The second targets the macroscopic behavior of the different reactor types (reactor models). The workshop will be made up of presentations and a discussion about the models and sub models.
Workshop dinner. All participants are invited to join a dinner on the evening before the workshop.
Agenda:
08:00–08:30 Introduction and presentation of participants
08:30–09:30 Modelling of fuel particles and gas phase
09:30–10:00 Coffee
10:00–12:00 Modelling of fuel particles and gas phase
12:00–13.00 Lunch
13:00–14:30 Reactor modelling
14:30–15:00 Coffee
15:00–16:30 Reactor modelling
16:30–17:00 Workshop summary and discussion of future work
