2. 1. Statistical Mechanical Studies of Aqueous solutions and Biomolecular Systems

   Author : Fernando Luis Barroso Da Silva; Beräkningskemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; highly charged macromolecules; dielectric discontinuity; dissociation constant; Tanford-Kirkwood model; protein mutation; electrostatic interactions; chemical potential; titration; biomolecules; computer simulations; radial distribution function; electrolyte solutions; continuum model.; Theoretical chemistry; quantum chemistry; Teoretisk kemi; kvantkemi;

   Abstract : This thesis is concerned with theoretical studies of aqueous solutions and biomolecular systems. Part of the present work is to understand equilibrium solvent and solute properties, while the other part is to study processes that occur in these solutions. READ MORE

4. 2. High resolution microstructural characterization of oxide thin films and interfaces

   Author : Nikolina Tuzla; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; oxides; Microstructure; TEM; thin films; interfaces; HAADF STEM; YSZ.; SrTiO3; 2DEG; LaAlO3; heterostructures;

   Abstract : Oxide interfaces can introduce properties that are different compared to thecorresponding crystal bulk properties. The properties can be tuned by changing thestructure. It has become clear that these oxide interface systems are potentiallysuitable for future electronic devices with unique and tailored properties. READ MORE

5. 3. Engineering ferroelectric domains and charge transport by proton exchange in lithium niobate

   Author : Michele Manzo; Katia Gallo; Marin Alexe; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lithium niobate; Ferroelectrics; Teknisk materialvetenskap; Materials Science and Engineering; Fysik; Physics;

   Abstract : Ferroelectrics are dielectric materials possessing a switchable spontaneous polarization, which have attracted a growing interest for a broad variety of applications such as ferroelectric lithography, artificial photosynthesis, random and dynamic access memories (FeRAMs and DRAM), but also for the fabrication of devices for nonlinear optics, etc. All the aforementioned applications rely on the control of the ferroelectric domains arrangement, or the charge distribution and transport.

6. 4. Ultra-wideband Millimeter-wave Antenna Arrays and Front-end Systems : For high data rate 5G and high energy physics applications

   Author : Imran Aziz; Dragos Dancila; Ville Viikari; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The demand for wireless data communications is rapidly increasing due to several factors including increased internet access, increasingly growing number of mobile users and services, implementation of the Internet of Things (IoT), high-definition (HD) video streaming and video calling. To meet the bandwidth requirement of new and emerging applications, it is necessary to move from the existing microwave bands towards millimeter-wave bands. READ MORE
