Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plant nanobionics; Nanoparticles; Chitosan-modified polyethyleneimine; Infiltration; CO2 capture; Photosynthesis;
Abstract :
Photosynthesis is an evolutionary marvel that not only sustains plant life but also profoundly shaped the climatic conditions necessary for the development of other advanced forms of life and the ecosystems we know today. During photosynthesis, plants harness the energy of light to convert carbon dioxide (CO2), one of the main greenhouse gases, into sugars for the growth of both themselves and organisms that consume plants, and oxygen that sustains life on Earth.

Keywords : layer-by-layer assembly; nanofibrillated cellulose; thin film; surface adsorption; polyelectrolytes;
Abstract :
The preparation of multifunctional films, coatings and membranes from natural, sustainable and low-cost raw materials has attracted considerable interest during the last decade. In this respect, cellulose-based products possess a great promise for research and industry due both to the availability of large amounts of material in nature and to the preparation of new classes of nano-sized and well-characterized building-blocks of cellulose from trees or annual plants.
