Wood based ionic diode

Wood and its derivatives are highly attractive materials, not only due to their sustainability, low cost, and biodegradability, but also because of their intrinsic porous and hierarchical structure, excellent mechanical properties, and versatile surface chemistry. In this work, we present an ionic diode based on bipolar membranes fabricated from two oppositely charged wood membranes. The

Novel bio-based, hygroscopic insulation materials for enhanced energy performance and robustness of buildings

The construction sector in Sweden stands for about 22% of total greenhouse gas emissions. Reducing the embodied carbon in new buildings can be achieved by a transition to bio-based insulation materials since conventional insulation accounts for about 20% of the total embodied carbon. Additionally, bio-based materials are hygroscopic, i.e. they absorb moisture from the air

Increased accessibility and reactivity of cellulose for high-performance derivatives

Cellulose is a renewable and biodegradable material, but its natural structure limits its use in some applications. Chemical modification can impart new properties to cellulose and expand its applications. This project will investigate methods to enhance cellulose reactivity and accessibility, aiming to improve the production of cellulose derivatives.https://www.kth.se/fpt/woodchem/research/cellulose-for-high-performance-derivatives-1.1244385

Diffusion and damage during delignification of wood biomass (D4mass)

Delignification is a crucial process in the pulp industry that separates lignin and cellulose, the two biobased raw materials with enormous potential. During this process, the removal of lignin through diffusion is coupled with the accumulation of damage in cell walls, causing cracks and changing the trajectory of diffusion. However, a mechanistic understanding and a

Circular, scalable, multifunctional wood aerogel 

Aerogels are attractive in various applications ranging from aerospace to energy storage due to low density and high specific surface area. Mainstream strategy to obtain lignocellulosic aerogels is bottom-up approach, disintegrating wood into nano building blocks (e.g. nanocellulose) followed by reassembling into aerogels. The complex and/or energy intensive processing are challenges. Top-down approach is an
