La investigación que se planteará a continuación se enfocará en el estudio de una propuesta de trasdosado de fibras prensadas y conformadas para que se simplifique e industrialice los actuales procesos en rehabilitación ...

Background: The increasing interest in replacing petroleum-based products by more sustainable materials in the packaging sector gives relevance to cellulose as a biodegradable natural resource. Moreover, its properties can ...

Bacterial cellulose was combined with wood cellulose papers in order to obtain biomaterials with increased barrier properties. For this purpose, different parameters were assessed: two producing bacterial strains ...

Over the past decade, bio-based polymers, especially in packaging, have gained a bigger role due to the over consuming of petrol derivates and the gradually growing concerns relating environment and sustainability issues. ...

The aim of the thesis is to develop technology for producing cellulose fatty acid esters that later will be used to produce fibrous materials by means of electrospinning. Main material of the study is cellulose-stearate ...

A TCF sulphite pulp, bleached at the laboratory scale with a laccase–violuric acid system and complemented with a pressurized hydrogen peroxide stage, was treated with two endoglucanases, one obtained from Paenibacillus ...

Several cellulosic substrates have been surface-functionalized with cyclomaltoheptaose (b-cyclodextrin, b-CD) using citric acid as a crosslinker agent to obtain new surface-modified materials able to release antiseptic ...

El treball va adreçat a posar a punt 3 mètodes d'anàlisi (UV, turbidimetria i digestió i anàlisi) per la determinació de la concentració de suspensions de nanopartícules en aigua. S'assajaran sistemes d'interès formats per ...

Bacterial cellulose (BC) has emerged as an attractive adsorptive material for antimicrobial agents due to its fine network structure, its large surface area, and its high porosity. In the present study, BC paper was first ...
