  2. 1. Early Hydration of Portland Cement

    Author : Rikard Ylmén; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SEM; freeze-drying; cement; calorimetry; nano-silica; carbonation; hydration; FTIR; infrared spectroscopy;

    Abstract : The production of cement is responsible forapproximately 7 % of the total CO2 emissions caused by man. To compensate for high energyconsumption and CO2 emission, thus making the utilization of concrete more sustainable,several strategies can be used. READ MORE

  4. 2. Exploration of Graphene-like 2D Materials for Energy Management and Interface Enhancement Applications

    Author : Ya Liu; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Industrial Application; Graphene-like 2D materials; Interface Enhancement; Energy Management;

    Abstract : Ever since the discovery of graphene in 2004, graphene-like 2D materials and their derivatives have attracted extensive investigations because of their exceptional physical and chemical properties. At present, the study of graphene-like 2D materials is at a stage where most of their outstanding physical and chemical properties have been discovered, but the technology for incorporating them into practical commercial products is rarely revealed.
