Battery technology and recycling alone will not save the electric mobility transition from future cobalt shortages
Zeng, Anqi; Chen, Wu; Dalgas Rasmussen, Kasper; Zhu, Xuehong; Lundhaug, Maren Cathrine; Mueller, Daniel Beat; Tan, Juan; Keiding, Jakob K.; Liu, LiTao; Dai, Tao; Wang, Anjian; Liu, Gang (Peer reviewed; Journal article, 2022)In recent years, increasing attention has been given to the potential supply risks of critical battery materials, such as cobalt, for electric mobility transitions. While battery technology and recycling advancement are ... -
Carbon neutrality of China's passenger car sector requires coordinated short-term behavioral changes and long-term technological solutions
Chen, Wu; Sun, Xin; Liu, Litao; Liu, Xiaojie; Zhang, Rui; Zhang, Shaohui; Xue, Jinjun; Sun, Qian; Wang, Minxi; Li, Xin; Yang, Jianxin; Hertwich, Edgar G.; Ge, Quansheng; Liu, Gang (Peer reviewed; Journal article, 2022)The passenger car sector accounts for nearly half of all transport-related emissions. Rapid decarbonization is therefore important but challenging, particularly in China, where, despite recent emission peak (by 2030) and ... -
Closing the loop: Tracking stocks and flows of steel from the end of useful life to re-melting
Rørtveit, Ingrid (Master thesis, 2014)Recycling steel scrap from different stages in the life cycle is an important input to secondary steel production and manufacturing. While flows and losses from pre-consumer processes are well known, there are considerable ... -
Comparative study of indirect tensile test and uniaxial compression test on asphalt mixtures: Dynamic modulus and stress-strain state
Chen, Hao; Alamnie, Mequanent Mulugeta; Barbieri, Diego Maria; Zhang, Xuemei; Liu, Gang; Hoff, Inge (Peer reviewed; Journal article, 2022)Dynamic modulus is an essential parameter for the performance characterisation of asphalt materials for performance prediction and pavement design. The Indirect Tensile (IDT) test and the Uniaxial Compression (UC) test are ... -
Influence of material factors on the determination of dynamic moduli and associated prediction models for different types of asphalt mixtures
Chen, Hao; Saba, Rabbira Garba; Liu, Gang; Barbieri, Diego Maria; Zhang, Xuemei; Hoff, Inge (Peer reviewed; Journal article, 2022)In a Mechanistic-Empirical (ME) pavement design system, the dynamic modulus is used to characterise asphalt mixtures, which are affected by many factors including environmental conditions and material properties. This study ... -
Interactive data visualization of the Norwegian phosphorus cycle, coupling phosphorus with dry matter and energy in a multi-layered material flow analysis model
Rud, Richard Olav (Master thesis, 2015)The utilization of data visualization to explore complex systems is arguably an indispensable method for increasing understanding of a specific problem domain. It is argued that visualization techniques for presenting ... -
Laboratory-based modelling of viscoelastic properties of asphalt pavement
Chen, Hao (Doctoral theses at NTNU;2023:207, Doctoral thesis, 2023)The Norwegian Public Roads Administration (NPRA) is running a project “VegDim” with the aim of developing and implementing a Mechanistic-Empirical (ME) pavement design system for Norwegian conditions. The traditional ... -
Prepare Russia to meet IPCC 2050, based on dynamic MFA approach for greenhouse gas emissions
Volsky, Uladzimir (Master thesis, 2012)An integrated MFA (Material Flow Analyse) model was developed for Russia, based on the year 2009. Integration was done between MFA, energy and greenhouse gas (GHG).Technologies in all production related processes of aluminium ... -
Rolling Out the Anthropogenic Aluminum Cycle: With Foci on Temporal, Geographical, and Emission Perspectives
Liu, Gang (Doktoravhandlinger ved NTNU, 1503-8181; 2013:95, Doctoral thesis, 2013)Anthropogenic metal cycles today confront three interconnected large challenges: an increasing global demand due to rising population and escalating industrialization and urbanization, a profound change of the global supply ...
