1. 1. Preparing Spatial Haptics for Interaction Design

   Författare :Jonas Forsslund; Eva-Lotta Sallnäs Pysander; Ylva Fernaeus; Jan Gulliksen; Karl-Johan Lundin-Palmerius; Karon MacLean; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; haptics; interaction design; surgery simulation; haptik; interaktionsdesign; medicinsk simulering; kirurgi; Människa-datorinteraktion; Human-computer Interaction;

   Sammanfattning : Spatial haptics is a fascinating technology with which users can explore and modify3D computer graphics objects with the sense of touch, but its application potentialis often misunderstood. For a large group of application designers it is still unknown,and those who are aware of it often have either too high expectations of what is technicallyachievable or believe it is too complicated to consider at all.

3. 2. Micro-reaction Mechanism Study of the Biomass Thermal Conversion Process using Density Functional Theory

   Författare :Xiaolei Zhang; Weihong Yang; Linda J. Broadbelt; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomass thermal conversion; cellulose pyrolysis; char steam gasification; adsorption; interaction; mechanism; quantum chemistry; density functional theory;

   Sammanfattning : Biomass, or bio-energy, is one of the most important alternative energies because of environmental concerns and the future shortage of fossil fuels. Multi-scaled bioenergy studies have been performed in the division of Energy and Furnace Technology, which included studies of macroscopic systems such as systems and reactors, modeling of computational fluid dynamics (CFD), and atomic/molecular level studies.

4. 3. Investigations of the retention mechanisms in hydrophilic interaction chromatography

   Författare :Ngoc Phuoc Dinh; Knut Irgum; Andrew J. Alpert; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; HILIC; hydrophilic interaction chromatography; adsorption isotherm; water enriched layer; multivariate data analysis; retention mechanism; separation; analytisk kemi; Analytical Chemistry;

   Sammanfattning : Hydrophilic interaction chromatography is well known as a powerful technique separation of polar and ionizable compound nowadays. However the retention mechanism of the technique is still under debate. Understanding retention mechanism would facilitate the method development using the technique and its future improvement.

5. 4. Formation and Decomposition of Platinum–Thallium Bond, Kinetics and Mechanism. Structural Characterization of Some Metal Cyanides in the Solid State

   Författare :Péter Nagy; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; metal–metal bond; platinum; thallium; kinetics; mechanism; stopped flow; oxidative addition; cyano complexes; edta; redox reaction; metal cyanides; X–ray diffraction; Raman; NMR; mercury; palladium; nickel; one dimensional wire;

   Sammanfattning : The kinetic and mechanistic features of a new series ofplatinum-thallium cyano compounds containing a direct andunsupported by ligands metal-metal bond have been studied insolution, using standard mix–and–measurespectrophotometric technique and stopped–flow method.These reactions are interpreted as oxidative addition of the cspecies to the square planar Pt(CN)42-complex.

7. 5. Adsorption of pinosylvin onto the structure of wood : mechanism and adsorption parameters

   Författare :Ildiko Mohammedne Ziegler; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

   Sammanfattning : Pinosylvin and polyhydroxybenzene derivatives are natural components of wood, known for their fungicidal/fungistatic properties. These components were used as adsorbates in the present investigation. LÄS MER
