  1. 21. Analytical Methods for High Molecular Weight UV Stabilizers

    University essay from KTH/Kemi

    Author : Elin Ljungström; [2022]
    Keywords : hindered amine light stabilizers; light stabilizers; polyolefins; LC-MS; HPLC; hindrade aminljusstabilisatorer; ljusstabilisatorer; polyolefiner; LC-MS; HPLC;

    Abstract : Utomhusprodukter gjorda i plast är sårbara för nedbrytning på grund av UV-energi från solljus. För att stoppa denna fotonedbrytning används UV-stabilisatorer i plastmaterial; en av huvudkategorierna är hindrade aminljusstabilisatorer (HALS, hindered amine light stabilizers). READ MORE

  2. 22. DINCH and DINP Plasticizers Alter Lipid Metabolism in 3T3-L1 cells

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Isabel Häggblom; [2022]
    Keywords : ;

    Abstract : Di(isononyl)cyclohexane – 1,2 dicarboxylate (DINCH) and Diisononyl phthalate (DINP) are high molecular weight compounds used as plasticizers. DINCH and DINP use on the market have been increasing recently to replace previously used phthalate plasticizers in polymeric products. READ MORE

  3. 23. Oligosaccharide Analysis - Assessment of the DNS Method and Specification of Glucans Processed with CGTase

    University essay from Lunds universitet/Bioteknik; Lunds universitet/Bioteknik (master)

    Author : Matilda Johansson; [2022]
    Keywords : CGTase; DNS; Chromatography; HPAEC; HPAE; Carbohydrate; Carbohydrates; Glucans; Cyclodextrin glycosyltransferase; Biotechnology; Bioteknik; Flory; Enza; Enzyme; Technology and Engineering;

    Abstract : In this study, the reagent 3,5-dinitrosalicylic acid (DNS) and high-performance anion exchange chromatography (HPAEC) were used for carbohydrate characterisation. It was revealed that the DNS reaction is not exclusive to reducing ends as commonly thought, but rather that the reagent reacts with other parts of the carbohydrate molecules as well. READ MORE

  4. 24. Effect of Endocrine Disruptor Chemicals(EDCs) Mixture G1 on Molecular Endpoints in Human Mesenchymal Stem Cells

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Wedyan Azeez Saleh Bahr; [2022]
    Keywords : ;

    Abstract : Endocrine disrupting chemicals (EDCs) are used in many every-day products but they can alter functions of the endocrine system. Exposure to these chemicals during early development can lead to long term health adversities. READ MORE

  5. 25. Deep learning for nanofluidic scattering microscopy

    University essay from

    Author : Gustaf Sjösten; [2021-06-09T11:22:05Z 2021-06-09T11:22:05Z 2021 2020]
    Keywords : data analysis; machine learning; deep convolutional neural networks; nanofluidic scattering spectroscopy; biomolecules; physical chemistry; dark-field microscopy;

    Abstract : A novel technique for label-free, real-time characterization of single biomolecules called Nanofluidic Scatter Microscopy (NSM) has recently been developed by a the Langhammer research group at Chalmers. We have created a machine learning (ML) framework consisting of deep convolutional neural networks such as U-nets, FCNNs, and YOLO in order to characterize single biomolecules through kymographs collected through NSM, as an alternative approach to a standard data analysis method (SA).
