  1. 1. Pharmaceutical Nanocomposites Structure–Mobility–Functionality Relationships in the Amorphous State

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Joel Hellrup; Denny Mahlin; Göran Alderborn; László Fábián; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; amorphous; pharmaceutical composites; solid state; structure; molecular mobility; spray-drying; freeze-drying; moisture sorption; physical stability; compression; Farmaceutisk vetenskap; Pharmaceutical Science;

    Abstract : Amorphous materials are found in pharmaceutical formulations both as excipients and active ingredients. Indeed, these formulations are becoming an essential strategy for incorporating drugs into well-performing solid dosage forms. READ MORE

  2. 2. Inorganic and organic polymer-grafted nanoparticles : their nanocomposites and characterization

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Carmen Cobo Sanchez; Eva Malmström; Henrik Hillborg; Anna Barros Timmons; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Si-ATRP; ATRP; polyelectrolytes; rGO; aluminium oxide; silica; CNF; CNC; PCL; LDPE; EBA; nanocomposites; matrix-free; extrusion; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Nanocomposites (NCs) have been widely studied in the past decades due to the promising properties that nanoparticles (NPs) offer to a polymer matrix, such as increased thermal stability and non-linear electrical resistivity. It has also been shown that the interphase between the two components is the key to achieving the desired improvements. READ MORE

  4. 4. Graphene-based nanocomposites for electronics and photocatalysis

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Ebrahim Chalangar; Håkan Pettersson; Magnus Willander; Omer Nour; Maria Messing; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Graphene; Zinc oxide; Silver iodine; Plasmonics; Nanocomposites; Conjugated electronics; Photocatalysis; Photodegradation;

    Abstract : The development of future electronics depends on the availability of suitable functional materials. Printed electronics, for example, relies on access to highly conductive, inexpensive and printable materials, while strong light absorption and low carrier recombination rates are demanded in photocatalysis industry.
