  1. 1. Anions and Additives for Lithium Battery Electrolytes

    Author : Johan Scheers; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; lithium batteries; additives; Raman spectroscopy; anions; ab initio; electrolytes; ion pairs;

    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

    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. 3. The use of Fenton chemistry for reducing the refining energy during TMP production the effect of free ferrous and free or chelated ferric ions

    University dissertation from Sundsvall : Mid Sweden University

    Author : Karin Walter; Mittuniversitetet.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    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

  4. 4. The rule of hydrogen and rare earth metals in the formation of protective metal-oxides

    University dissertation from Stockholm : Materialvetenskap
