  1. 11. Assessment of promoter regulation in Pseudomonas putida using GFP and flow cytometry

    University essay from Lunds universitet/Teknisk mikrobiologi

    Author : Luka Cululejevic; [2022]
    Keywords : applied microbiology; Pseudomonas putida; promoter characterization; aromatic compounds; vanillin; guaiacol; Biology and Life Sciences;

    Abstract : Lignin is found in all biomass and is an abundant natural source of aromatic compounds. It has the potential to serve as a renewable raw material for a variety of chemicals currently derived from fossil fuel sources such as muconic acid, an important platform chemical. Kraft lignin is a waste stream from the pulp and paper industry. READ MORE

  3. 12. Mechanical properties of viscose filament : Made from recycled cotton textile and softwood dissolving pulp

    University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Author : Sanne Karlsson; [2022]
    Keywords : Recycled cotton textile; recycled textile; dissolving pulp; wood dissolving pulp; softwood; viscose dope; viscose filament; the viscose process; spinning process; Återvunnen bomullstextil; återvunnen textil; dissolvingmassa; trädissolvingmassa; barrved; viskos dop; viskosfilament; viskosprocessen; spinningprocess;

    Abstract : The textile industry is one of the largest industries in the world and it causes up to 10 % of the global greenhouse gas emissions. With large environmental issues of cotton- and oil-based textiles, other options are explored such as man-made fibers producing fibers like viscose and lyocell. READ MORE

  4. 13. Investigating the process parameters that influence the z-strength of liquid paperboard using data mining and machine learning

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Gustav Thaung Tolförs; [2021]
    Keywords : paperboard; liquid paperboard; z-strength; process parameters; machine learning; data mining;

    Abstract : Parameters affecting the z-strength of liquid paperboard (LPB) has been analyzed and identifiedusing data mining and machine learning on 6 years of operational data from a multi-ply LPB mill, and control and stabilizing of them was proposed. Linear regression models were built for 9 articles with satisfactory results, and whose attributes were further analyzed as the most important parameters for the z-strength. READ MORE

  5. 14. Thermally insulating carbon foams from carbonized kraft lignin

    University essay from KTH/Fiber- och polymerteknologi

    Author : Isabelle Hernodh Svantesson; [2021]
    Keywords : Carbon foams; thermal insulation; kraft lignin; carbonization; thermal conductivity; Kolskum; värmeisolering; kraftlignin; karbonisering; värmeledningsförmåga;

    Abstract : Kolmaterial, såsom kolfibrer och kolskum, används som värmeisolatorer i applikationer vid höga temperaturer. För närvarande härleds dessa material från fossilbaserade källor, vilket tyder på ett behov av att hitta alternativa kandidater baserade på förnybara källor. READ MORE

  6. 15. Development of pulp fiber charge in oxygen delignification of softwood

    University essay from KTH/Fiber- och polymerteknologi

    Author : Jiahao Mai; [2021]
    Keywords : fiber; fiber charge; fine content; oxygen delignification; softwood; fiber; fiberladdning; finmaterial; syrgasdelignifiering; barrved;

    Abstract : Esteves et.al. 2020 visade att syrgasdelignifiering ökar den totala fiberladdningen men leder inte alltid till ökad pappersstyrka. Denna studie syftar till att undersöka hur fiberladdning påverkar massans egenskaper. READ MORE
