2. 16. Alternative Energy Harvesting and Conversion Systems Based on Nanostructured Heterostructures

   Author : Mojtaba Gilzad Kohan; Alberto Vomiero; Andrea Li Bassi; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; light harvesting; solar supercapacitors; energy conversion; Photovoltaic; energy storage; metal oxide semiconductors; Experimentell fysik; Experimental Physics;

   Abstract : Conversion and storage of the solar radiation into applicable forms of energy, using ubiquitous materials is of central importance that quests several disciplinary fields in both applied technology and fundamental science. Harnessing the solar energy received by the earth has the potential to replace the current sources of energy and it is imperative for sustainable development. READ MORE

4. 17. Trees to supercapacitors: green energy storage for sustainable future

   Author : Bony Thomas; Kristiina Oksman; Mohini Sain; Milo Shaffer; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trä och bionanokompositer; Wood and Bionanocomposites;

   Abstract : Currently the world is transitioning to a fossil free and circular economy-based development to achieve the environmental and climate objectives along with the sustainable development goals. To achieve this target, efficient use of resource materials is important, which can increase the lifetime and economic value of the resources while decreasing both the extraction of new raw materials and landfill waste.

5. 18. Control and Optimization of Fuel Cell Based Powertrain for Automotive Applications

   Author : Qian Xun; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power distribution; Cut-off frequency; Fuel cell; Chance-constraint co-design optimization; Supercapacitors; Convex programming; Electric vehicles; Load disturbance compensator; DC-link voltage; Robust co-design optimization; Batteries;

   Abstract : Fuel cell powered electric vehicles, with fast-refueling time, high energy density, and zero CO2 emissions, are becoming a promising solution for future fossil-free transportation. However, the relatively slow dynamic response and the inability of recovering the regenerative energy make vehicles solely powered by fuel cells not an immediately attractive solution. READ MORE

6. 19. Hybrid Materials for Wearable Electronics and Electrochemical Systems

   Author : Mehmet Girayhan Say; Isak Engquist; Magnus Berggren; Shizuo Tokito; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wearables; Green electronics; Organic electronics; Conductive polymers;

   Abstract : Flexible electronic systems such as wearable devices, sensors and electronic skin require power sources and sensing units that are mechanically robust, operational at low bending radius, and environmentally friendly. Recently, there has been an enormous interest in active materials such as thin film semiconductors, conductive polymers, and ion-electron conductors. READ MORE

7. 20. Carbon nanomaterial-based interconnects, integrated capacitors and supercapacitors

   Author : Muhammad Amin; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbon nanotubes; Integrated capacitors; vertically aligned carbon nanofibers; Interconnects; PECVD; Interdigitated micro-supercapacitors;

   Abstract : The constant miniaturization and steady performance improvement of electronics devices have generated innovative ideas such as internet of thing (IoT), which also includes devices with integrated energy sources. The high performance is conceived by the high density of the devices on a chip leading to a high density of interconnects, to connect these devices to outside world. READ MORE
