  1. 1. Biopolymers processed and used as enzyme carriers

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Dániel Mészáros; [2023]
    Nyckelord :Biobased materials; plasticized sodium alginate; water stability; extraction kinetics; enzyme carrier; Biobaserade material; Mjukgjort natriumalginat; Vattenstabilitet; extraktionskinetik; Enzymbärare;

    Sammanfattning : Syftet med detta masterprojekt var att undersöka möjligheten att använda biobaserat, mjukgjort natriumalginat (NaAlg) som enzymbärare. Alginaterna görs traditionellt bearbetbara genom att tillsätta olika mjukgörare, såsom polyoler (glycerol, sorbitol, etc.), i detta arbete användes glycerol. LÄS MER

  3. 2. Particulate matter analysis from engine outlet in heavy-duty diesel vehicles : A study of soot reactivity, morphology and ash-to-soot ratio from the outlet of 6-cylinder and 8-cylinder diesel engines.

    Master-uppsats, KTH/Kemiteknik

    Författare :Tayisiya Vlasenko; [2023]
    Nyckelord :Diesel engine; particulate matter; kinetics; soot; heavy-duty vehicles; Dieselmotor; partiklar; kinetik; sot; tunga fordon;

    Sammanfattning : De ökande luftföroreningarna i Europa är ett allvarligt miljöproblem, och vägtransporterna är en av de största orsakerna till detta. För att ta itu med detta problem och uppfylla nya utsläppskrav måste efterbehandlingssystemen för avgaser förbättras. LÄS MER

  4. 3. Solubility of arsenic in untreated and ZVI-treated contaminated aquifer material

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Oscar R. Davies; [2022]
    Nyckelord :Hjältevad; zerovalent iron; phosphate extraction; Oxalate extraction; Visual MINTEQ; geochemical modelling;

    Sammanfattning : Arsenic (As) is a toxic element to all life and exists in nature both naturally and anthropogenically. Naturally As contaminated soils are formed due to high geogenic background As concentrations which is released when bedrock is eroded. Asia is a continent with a high amount of naturally As contaminated soils and groundwater. LÄS MER

  5. 4. Polymerization of isatin towards polymers for anion exchange membranes and gas separation applications

    Master-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Simone Facchini; [2022]
    Nyckelord :organic chemistry; membranes; isatin; polymers; Chemistry;

    Sammanfattning : In a world where the problem of energy resources, pollution and all aspects related to these issues becomes more and more dominant, a greater commitment is needed in the search for solutions. The goal of this project is to make a contribution to the research and development of new materials to reduce the environmental impact in some fields. LÄS MER

  7. 5. Characterisation of free and conjugated protease inhibitors from Solanum tuberosum

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för kemi - BMC

    Författare :Kristoffer Lundmark; [2017]
    Nyckelord :enzyme; trypsin; chymotrypsin; pancrease protease; serine protease inhibitors; SPI; potato tubers; potato; Solanum tuberosum; immobilized; aluminium oxide membranes; inhibitor-enzyme interaction;

    Sammanfattning : The main purpose of the master thesis project is to investigate the influence of selected serine protease inhibitors (SPI) on the catalytic action of the serine proteases chymotrypsin and trypsin, in a conjugated and non-conjugated state. The inhibitors included for this study were extracted from Solanum tuberosum, i.e.common potato. LÄS MER
