1. 1. Graphene : a vision to the future of smart E-Textile application

   Författare :Milad Asadi; Nawar Kadi; Priniotakis Georgios; Högskolan i Borås; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; graphene; graphene-coated e-textiles; catalyst immobilisation; hybrid graphene-catalyst multifunctional textiles; dye removal; e-textile; electro-Fenton; Fenton; wastewater treatment; Textil och mode generell ; Textiles and Fashion General ;

   Sammanfattning : Smart textile is a term referring to the textiles that could interact with their environment, receiving input and giving output based on their applications. Among smart textiles, electrically driven smart textiles (E-textiles) are being produced by various methods and materials integrated with textile substances. LÄS MER

3. 2. Fenton Pre-treatment of a Birch Kraft Pulp for MFC preparation

   Författare :Pia Hellström; Helena Håkansson; Anette Heijnesson Hultén; Magnus Paulsson; Monica Ek; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microfibrillated cellulose; Fenton chemistry; carbonyl groups; surface charge; total charge; Enzymatic hydrolysis; Tensile strength; z-directional strength; Chemical Engineering; Kemiteknik;

   Sammanfattning : The potential to use acidic hydrogen peroxide in the presence of ferrous ions (Fenton’s reagent) as a pre-treatment when producing microfibrillar cellulose (MFC) from a fully bleached birch (Betula verucosa) kraft pulp was investigated and the properties of the produced MFC was compared to the properties of a MFC produced with enzymatic pre-treatment with a monocomponent endoglucanase (FiberCare® R). The mechanical treatment to MFC was performed in a laboratory colloid mill or in a pilot high-pressure homogeniser and the pre-treated pulps as well as the produced MFCs were chemically and morphologically characterised.

4. 3. Bioelectronic Approaches for On-Demand Generation of Reactive Oxygen Species

   Författare :Eva Miglbauer; Eric Glowacki; Oliya Abdullaeva; Lars Peter Nielsen; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ROS; ORR; WOR; Fenton reaction; Electrolysis; Bioelectronics;

   Sammanfattning : Reactive oxygen species (ROS) are an integral part of our lives. They perform essential functions in our biology and are, due to their high oxidative power, key molecules in advanced oxidation processes in industrial applications such as treatment of wastewater. LÄS MER

5. 4. Surface reactions on metallic nanoparticles : Ligand adsorption, metal release, and reactive oxygen species generation

   Författare :Amanda Kessler; Inger Odnevall; Tommy Nylander; KTH; []

   Sammanfattning : Humans are exposed daily to metallic nanoparticles (Me NPs) from multiple sources which can have both natural and anthropogenic origins. Such exposures take place via different routes including inhalation and skin contact and may result in adverse health effects. LÄS MER

7. 5. Analysis of PAHs and their transformations products in contaminated soil and remedial processes

   Författare :Staffan Lundstedt; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; polycyclic aromatic hydrocarbons; PAHs; degredation; transformation; formation; accumulation; oxidation products; metabolites; oxogenated polycyclic aromatic hydrocarbons; oxy-PAHs; soil; gasworks; remediation; bioremediation; bioslurry; wood-rotting fungi; Fenton´s reagent; avaliability; bioavaliability; chemical analysis; extraction; pressurized liquid extraction; PLE; accelerated solvent extraction; ASE; Miljökemi; Environmental chemistry; Miljökemi; analytisk kemi; Analytical Chemistry;

   Sammanfattning : Soil that is heavily contaminated with polycyclic aromatic hydrocarbons (PAHs) is often found at the sites of former gasworks and wood-impregnation plants. Since PAHs are toxic these sites represent a hazard to human health and the environment, and therefore they need to be treated, preferably by a method that destroys the contaminants, and thus eliminates the problem permanently.
