Cellulosed based foams for water purification

TREESEARCH

We have designed foams which are built only from green components and can be prepared in up-scalable and easy manner: blending and oven-drying. Amyloid nanofibrils are used mainly as a foaming agent and cellulose nanofibrils are playing the role of the main visco-elastic stabilizer. We also use covalent cross-linking to enhance foam resistance towards capillary

Structure-properties relationship of covalently crosslinked cellulose networks

TREESEARCH

In this work, the structure-property relationship of covalently crosslinked cellulose networks is studied by utilizing surface modified cellulose nanofibrils and polymer links of defined structure and molecular weight. The effect of molecular weight, chemical functionality and concentration on specific surface area, swelling, and mechanical properties of the hydrogel networks will be investigated.

BIOdegradable vegan networks from REcycled agro-food waste as sustainable single-use abSORBents (BioRESorb)

TREESEARCH

The objective is to develop biodegradable absorbents containing nonwoven fiber networks from agro-food biomass waste. The material's structure-absorption relationship will be investigated and designed to make a fully bio-based absorbent core encapsulated in a natural nonwoven fabric. The raw materials will also be combined with other natural polymers to provide additional functionality (antimicrobial or binding

Atomistic understanding of biomass interaction with hydrotreating catalysts

TREESEARCH

The development of catalysts to upgrade renewable feedstocks is vital for a sustainable future. Alternative feedstocks typically differ in chemical composition compared to fossil-based feedstocks and to further develop catalytic materials that enable efficient and environmentally friendly chemical processes, it is necessary to understand the functional mechanisms of these materials in detail.The high oxygen content

Bio-sourced, oven-dried and wet-stable foams based on cellulose and amyloid nanofibrils

TREESEARCH

In the recent decades, foams have been extensively used for different applications such as: packaging, thermal and acoustic insulation, energy storage, and water purification. However, fabrication of foams from renewable resources through green methods with scale-up potential is challenging. In this context, cellulose nanofibrils (CNFs) as the most abundant bio-derived nanofibrils with outstanding physical properties

Structure-property relationships in lignin-based porous carbon materials for water purification

TREESEARCH

Good water quality is essential to human health, social and economic development, as well as the ecosystem. Industrialization and urbanization, together with the explosive population growth, have caused a great challenge for maintaining safe and clean water resources. Among many strategic and research activities for water protection, a direct approach is to develop biobased porous

Defibrillation of cellulosic substrates by novel bio-based ionic liquids

TREESEARCH

New bio-based ionic liquids were developed as a greener and simple pathway for the activation of cellulosic substrates compatible with chemical modification (such as in situ polymerization). Preliminary experiments showed that these ionic liquids promote swelling/dispersing/defibrillation/partial dissolution of cellulose while retaining cellulose I crystalline structure after regeneration (full dissolution is not achieved). To get a

Cellulose-based organic solar cells via spray deposition

TREESEARCH

In this project, we use spray deposition to fabricate cellulose-based, flexible organic solar cells. We use TEMPO-cellulose nanofibrils (TEMPO-CNF) as sustainable substrate material, flexible silver- or copper-nanowires (AgNW-/CuNW) as electrode material, conductive poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) as electron blocking layer, and a mixture of poly(3 hexylthiophene) (P3HT) and [6,6]-phenyl C61 butyric acid methylester (PCBM) as

Bottom-up assembly of synthetic plant cells

TREESEARCH

Recently, isolated CNFs has been utilized as outer cell wall to assemble around micro containers (Paulraj, T. et al., Nat. Comm., 2020). In such an assembly termed as “plantosomes” or synthetic plant cell, the lipid growth was regulated by changes in the pH or ions, similar to what occurs in plant cells. This project focuses
