  2. 1. External enablers and new venture creation : How characteristics of environmental changes and enabling mechanisms influence entrepreneurial responses

    Author : Jiyoung Kim; Daniel Pittino; Francesco Chirico; Per Davidsson; Matthew S. Wood; Jönköping University; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : Changes in the external environment—whether technological breakthroughs, natural environmental disasters, regulatory reforms, economic shifts, sociocultural movements, or demographic transitions—provide the essential enablement of entrepreneurial endeavors and outcomes. Despite extensive existing research on this topic, the predominant focus on a single type of change has hindered the attainment of broadly generalizable insights or advancements in theoretical and practical knowledge.

  4. 2. Biosynthesis, interactions, and structure of native lignin

    Author : Ioanna Sapouna; Lauren S. McKee; Francisco Vilaplana; Claudia Crestini; KTH; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; lignin; biomass valorization; extraction; tissue culture; lignin nanoparticles; wood aerogels; lignin; biomassavalorisering; extraktion; vävnadsodling; lignin nanopartiklar; trä aerogeler; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Wood biomass is an important resource in the development ofstrategies towards replacement of fossil-based materials. Woodcomprises cellulose, hemicelluloses and lignin, in amounts thatvary between species. READ MORE

  5. 3. Particles from biomass combustion -Characteristics and influence of additives

    Author : Linda S Bäfver; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; combustion; particle emission; wood; biomass; cereals; wood pellets;

    Abstract : AbstractHigh particle concentration in the air is a health risk, and particles from domestic biomass combustion are a significant particle source. In larger boilers, particles are an important element in the build-up of deposits on heat transfer surfaces, causing increased operation and maintenance costs. READ MORE

  6. 4. Micromechanics of softwoods in the transverse plane : effects on cell and annual ring scales
