  1. 1. An investigation of the interactions between clay nanoplatelets in the presence of monovalent and divalent salts, as well as cationic peptides utilising atomistic molecular dynamics

    University essay from Lunds universitet/Kemiska institutionen

    Author : Mona Koder Hamid; [2020]
    Keywords : clay; molecular dynamics simulations; physical chemistry; fysikalisk kemi; theoretical chemistry; teoretisk kemi; Chemistry;

    Abstract : Clays are negatively charged nanoplatelets with a layered silicate structure. It has been observed from small angle X-ray scattering measurements, and coarse-grained molecular dynamics simulations (CG-MD) that clay nanoplatelets are able to form stacks, known as tactoids, in the presence of divalent or multivalent counterions [8, 5].

  2. 2. Water Insoluble Fraction of Nopal (Opuntia ficus) Cladodes Beneficially Affects Postprandial Appetite-related Variables, while the Soluble Fraction Has No Effect: A Randomized Crossover Study in Healthy Volunteers

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Phuong Dung Kieu; [2020]
    Keywords : Nopal cladodes; appetite variables; dietary fiber; hydrolysis index; obesity; applied nutrition; food chemistry; industriell näringslära; livsmedelskemi; Medicine and Health Sciences;

    Abstract : Introduction: The world has witnessed a global trend of increasing obesity, which is directly linked to non-communicable diseases, such as type 2 diabetes (T2D). The epidemic of obesity is largely associated with consumption of high calorie diets and low physical activity. READ MORE

  3. 3. Aqueous self-assembly behaviour alteration derived from primary structure changes of model peptides

    University essay from Lunds universitet/Kemiska institutionen

    Author : Marcus Bäcklund; [2020]
    Keywords : Model peptides; self-assembly; SAXS; FTIR; CD; physical chemistry; fysikalisk kemi; Chemistry;

    Abstract : Understanding of the self-assembly behaviour of peptides is of great interest within several different areas such as neurodegenerative diseases, biotechnology, and peptide pharmaceuticals. In this work we have compared the impact on the self-assembly behaviour derived from systematic changes of the primary structure of A8K, where A denotes alanine and K lysine. READ MORE

  4. 4. Factors influencing the generation of carbon monoxide in fires partially suppressed through water mist application

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Haydn Lewis; [2020]
    Keywords : Fire safety engineering; water mist; fire suppression; carbon monoxide; water; combustion; Technology and Engineering;

    Abstract : Fires in the built environment typically consist of diffusion flames with inefficient mixing of fuel and oxygen, resulting in a degree of incomplete combustion and the generation of carbon monoxide. Fire suppression systems, used to control the growth and spread of fire, influence the combustion reaction process. READ MORE

  5. 5. Benchmarking Physical Properties of Water Models

    University essay from Uppsala universitet/Molekyl- och kondenserade materiens fysik

    Author : Tomas André; [2019]
    Keywords : Water Models; Molecular Dynamics; Properties of water; MD; Simulation; GROMACS;

    Abstract :     Water is a fundamental part of life as we know it, and by that also a fundamental for biology, chemistry, and parts of physics. Understanding how water behaves and interacts is key in many fields of all these three branches of science. READ MORE
