2. 1. Growth and Characterization of ZnO Nanocrystals

   Author : Leif KE Ericsson; Kjell O Magnusson; Lars SO Johansson; Hanmin M Zhang; Omer Nour; Karlstads universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; ZnO; Nanocrystals; Surface physics; XPS; SEM; AES; AFM; STM; Physics; Fysik;

   Abstract : The understanding of surfaces of materials is of crucial importance to all of us. Considering nanocrystals (NCs), that have a large surface to bulk ratio, the surfaces become even more important. Therefore, it is important to understand the fundamental surface properties in order to use NCs efficiently in applications. READ MORE

4. 2. Type-II interband quantum dot photodetectors

   Author : Oscar Gustafsson; Mattias Hammar; Wenquan Ma; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; photodetector; quantum dot; infrared; MOVPE; thermal imaging; type-II; photoluminescence; III V; InSb; InGaSb; InAs; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Abstract : Photon detectors based on single-crystalline materials are of great interest for high performance imaging applications due to their low noise and fast response. The major detector materials for sensing in the long-wavelength infrared (LWIR) band (8-14 µm) are currently HgCdTe (MCT) and AlGaAs/GaAs quantum wells (QW) used in intraband-based quantum-well infrared photodetectors (QWIPs).

5. 3. A Biotechnology Perspective on Silicon Nanowire FETs for Biosensor Applications

   Author : Nima Jokilaakso; Amelie Eriksson Karlström; Christer Wingren; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The study of silicon nanowire-FET-based electronic biosensor applications is an emerging scientific field. These biosensors have the benefit of being theoretically extremely sensitive and reports of down to femtomolar (fM) levels of biomolecule detection have been reported. READ MORE

6. 4. High-quality InP on Si and concepts for monolithic photonic integration

   Author : Carl Junesand; Sebastian Lourdudoss; Wolfgang Stolz; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : As the age of Moore’s law is drawing to a close, continuing increase in computing performance is becoming increasingly hard‐earned, while demand for bandwidth is insatiable. One way of dealing with this challenge is the integration of active photonic material with Si, allowing high‐speed optical inter‐ and intra‐chip connects on one hand, and the economies of scale of the CMOS industry in optical communications on the other.

7. 5. Application of magnetic nanoparticles and reactive filter materials for wastewater treatment

   Author : Ramnath Lakshmanan; Gunaratna Kuttuva Rajarao; Erik Dahlquist; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reactive filter materials; magnetic nanoparticles; wastewater treatment process; nutrient reduction; sludge water content; toxicity of magnetic nanoparticles;

   Abstract : Lately sewage wastewater treatment processes (WWTP) are facing challenges due to strict regulations in quality of effluent standards and waste production. The reuse of wastewater treatment effluents is rapidly gaining attention as a means of achieving sustainable water supply. Therefore, new methods are required to achieve an efficient WWTP. READ MORE
