1. 1. Development of rotation electron diffraction as a fully automated and accurate method for structure determination

   Författare :Bin Wang; Xiaodong Zou; Andy Stewart; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; electron crystallography; structure determination; structure refinement; metal-organic framework; guest molecules; software development; automation; hierarchical cluster analyses; high-throughput data processing; data merging; frame orientations; least-squares optimization; data processing; TEM goniometer; Inorganic Chemistry; oorganisk kemi;

   Sammanfattning : Over the past decade, electron diffraction methods have aroused more and more interest for micro-crystal structure determination. Compared to traditional X-ray diffraction, electron diffraction breaks the size limitation of the crystals studied, but at the same time it also suffers from much stronger dynamical effects. LÄS MER

3. 2. Investigation of surface and interface phenomena in silicon and silicon dioxide systems

   Författare :Yong-Bin Wang; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The characterization of a thin silicon dioxide (SiO2) film close to the silicon dioxide -silicon interface is very important in understanding and improving solid state electronic and optoelectronic devices. The refractive index, the dielectric constant, and the density of oxide film, are all related to the chemical composition and porosity (voids) of the films. LÄS MER

4. 3. Dual-ion Conducting Nanocompoiste for Low Temperature Solid Oxide Fuel Cell

   Författare :Xiaodi Wang; Mamoun Muhammed; Zhu Bin; Peter Lund; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fuel cell; Nano; Composite; Conducting; Electrolyte; SRA - Energy; SRA - Energi;

   Sammanfattning : Solid oxide fuel cells (SOFCs) are considered as one of the most promising power generation technologies due to their high energy conversion efficiency, fuel flexibility and reduced pollution. There is a broad interest in reducing the operating temperature of SOFCs. LÄS MER

5. 4. Ionic Conducting Composite as Electrolyte forLow Temperature Solid Oxide Fuel Cells

   Författare :Xiaodi Wang; Mamoun Muhammed; Zhu Bin; Per H Alvfors; KTH; []
   Nyckelord :;

   Sammanfattning : Solid oxide fuel cells (SOFCs) are considered as one of the most promising powergeneration technologies due to their high energy conversion efficiency, fuel flexibilityand reduced pollution. The current SOFCs with yttria-stabilized zirconia (YSZ)electrolyte require high operation temperature (800-1000 °C), which not only hinderstheir broad commercialization due to associated high cost and technologicalcomplications.

7. 5. Fluorescent quantum dots and graphene-based sensors for forensic applications

   Författare :Johnny Jussi; Ying Fu; Simon Dunne; Qin Wang; Ingemar Petermann; Xin Wang; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Graphene; Quantum Dots; Blood; Forensics; Drugs; Biologisk fysik; Biological Physics;

   Sammanfattning : A key emerging concept within the forensic sciences today areportable measurementdevices, where a much more efficient usage of the resources involved with crime-solving is possible if confirmatory measurements can be realised directly at a crimescene with such devices. Today, the majority of the presently used methods duringcriminal investigation at a crime scene involves measurements of a presumptivenature, which is a vital tool as it enables the screening of samples.
