1. Anions and Additives for Lithium Battery Electrolytes
Abstract : Based on the atomic postulate, which is now more than 2400 years old, scientists have developed very advanced tools for studying the material world. With the potential realized with modern computers, more and more sophisticated methods are available for predicting real material properties, even from simple theoretical model systems. READ MORE

2. Synthesis, Characterization and Applications of Metal Oxide Nanostructures
Abstract : The main objective of nanotechnology is to build self-powered nanosystems that are ultrasmall in size, exhibit super sensitivity, extraordinary multi functionality, and extremely low power consumption. As we all know that 21st century has brought two most important challenges for us. One is energy shortage and the other is global warming. READ MORE

3. Asymmetric and symmetric hydration of hydrated anions in aqueous solution
Abstract : The interaction between solvent and solute is a very important chemical property that has large impact on the chemical reactions taking place. In Paper I and II the structure of hydrated sulfite, selenite and selenate in aqueous solutions are determined and compared. READ MORE

4. The use of Fenton chemistry for reducing the refining energy during TMP production : the effect of free ferrous and free or chelated ferric ions
Abstract : The potential of using acid hydrogen peroxide under Fenton conditions to lowerthe electrical energy consumed during the production of Black spruce (Piceamariana) thermomechanical pulp (TMP) was investigated in pilot scale. Thechemical system, which consisted of ferrous sulphate, hydrogen peroxide andoptionally an enhancer (such as a chelating agent), was evaluated as an inter-stagetreatment. READ MORE

5. The rule of hydrogen and rare earth metals in the formation of protective metal-oxides
Abstract : The effects of hydrogen and rare earth metal (REM) additionson the oxidation behavior of metals and alloys that formchromia, alumina and zirconia in 20 mbar O2and/or H2O have been investigated at elevated temperatures.The metal-gas reactions were studied by the use of isotopicallylabeled gas in combination with mass spectrometry and bymeasuring changes in the total pressure in a closed reactionchamber.
