  1. 26. FTIR method for analysis of synthesis gas

    University essay from Institutionen för fysik, kemi och biologi; Tekniska högskolan

    Author : Marina Broberg; [2013]
    Keywords : FTIR; infrared spectroscopy; synthesis gas; syn gas; vibration mode; symmetric operation; Michelson interferometer;

    Abstract : The research institute ETC in Piteå is working with energy technical research and development. Today, much work revolves around research about renewable sources for fuel. In one project, biomass such as wood pellet is heated up while producing synthesis gas. The synthesis gas is then analyzed using three different GC techniques. READ MORE

  3. 27. Effects of ethylene on secondary xylem formation in Arabidopsis thaliana

    University essay from SLU/Dept. of Forest Genetics and Plant Physiology

    Author : Haley Rupp; [2013]
    Keywords : Arabidopsis thaliana; Ethylene; ACC; Secondary xylem; Cell wall chemistry; Lignin;

    Abstract : Ethylene has myriad roles as a plant hormone, ranging from senescence and defending against pathogen attacks to fruit ripening and interactions with other hormones. It has been shown to increase cambial activity in poplar, but the effect on wood formation in Arabidopsis hypocotyl has not previously been studied. READ MORE

  4. 28. Nanocellulose Based Films : Improved Mechanical And Gas Barrier Properties

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Philip Lamberstam; [2012]
    Keywords : ;

    Abstract : Microfibrillated cellulose (MFC) films have been prepared to demonstrate the potential of the material in order to see if it is a possibility to replace most parts of petroleum-based plastics. MFC is produced by mechanically delaminating the wood fiber cell wall into individual nano-fibrils. READ MORE

  5. 29. Inverkan av röjning och gödsling på mikrofibrillvinkeln i tallens (Pinus sylvestris L.) ungdomsved

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Björn Henningsson; [2012]
    Keywords : skogsskötsel; vedcell; cellvägg; kambial ålder; vedegenskaper; kvalitet; juvenil; silvicultural regime; wood cell; cell wall; cambial age; wood structure; quality; juvenile;

    Abstract : Tall (Pinus sylvestris L.) är ett av Sveriges viktigaste trädslag. Med ökad efterfrågan på vedråvara samt ökade krav på naturavsättningar är det viktigt att öka produktionen i skogen. Röjning och tidig gödsling ger ökad volymproduktion men kan ge icke önskvärd påverkan på vedegenskaper som ökad mikrofibrillvinkel (MFV). READ MORE
