  1. 6. Knowledge Distillation of DNABERT for Prediction of Genomic Elements

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Joana Palés Huix; [2022]
    Nyckelord :Knowledge distillation; Transformers; BERT; Genomics; Promoter identification; Explainability;

    Sammanfattning : Understanding the information encoded in the human genome and the influence of each part of the DNA sequence is a fundamental problem of our society that can be key to unveil the mechanism of common diseases. With the latest technological developments in the genomics field, many research institutes have the tools to collect massive amounts of genomic data. LÄS MER

  3. 7. Life Cycle Assessment of a small scale, solar driven HVR water purification system

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Sharang Kolathur; [2022]
    Nyckelord :life cycle assessment; air gap membrane distillation; solar energy; levelized cost; grid operated system; livscykelanalys; luftgapmembrandestillation; solenergi; utjämnade kostnader; nätdrivet system;

    Sammanfattning : Water purification systems have made access to drinking water easier by treating water sources which previously could not be used for drinking. Such systems however require energy and materials to build and operate which means they have environmental impacts. LÄS MER

  4. 8. 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

  5. 9. Negative CO2 Emissions from Chemical Looping Combustion: Gas Cleaning for CO2 Storage

    Master-uppsats, KTH/Kemiteknik

    Författare :Laura Raud Pettersson; [2022]
    Nyckelord :Chemical Looping Combustion; Flue Gas Treatment; Negative emissions; Biomass; CCS; Linde Hampson; Cryogenic Separation; Kemcyklisk Förbränning; Rökgasrening; Negativa Utsläpp; CCS; Biomassa; Linde Hampson; Kryogen Destillation;

    Sammanfattning : Kemcyklisk förbränning (CLC) involverar en icke komplex separation av den bildade koldioxiden (CO2) efter förbränningen eftersom syret (O2) överförs till bränslet via en syrebärare som cirkulerar mellan luft- och bränslereaktorn. Eftersom O2 separeras effektivt från kvävgasen (N2) i luftreaktorn, erhålls en produkt gas som till majoriteten består av CO2 och vatten (H2O). LÄS MER

  7. 10. Prospective Life Cycle Assessment of an Electrochemical Hydrogenation Process Over a Nickel Foam Cathode

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Hanson Appiah-Twum; [2022]
    Nyckelord :Scale-up; early process design; catalysis; environmental impact; hotspot analysis; green chemistry;

    Sammanfattning : The need for a safe and sustainable chemical industry has called for the development of emerging technologies with improved environmental performance. In this study, an emerging electrochemical hydrogenation process over Ni foam is being developed at the laboratory scale with an expectation of less environmental impacts than a conventional palladium on carbon hydrogenation process.
