Title: Solution-Processed Organic Light-Emitting Devices
Abstarct: Organic light-emitting devices (OLEDs) have very promising applications in display, lighting, visible light communication, and medical treatment, which make them attractive in fundamental and applied researches. Currently, the manufacture of OLED panels mainly rely on high-vaccum thermal evaporation, which is very expensive and complicated. To address this issue, solution-processed OLEDs are favorable due to the merits of large-area and low-cost. In this talk, the state-of-the-art spin-coated OLEDs will be presented and explained, includingg material selection and device engineering. In addition, the innovation of transfer printing and inkjet printing for solution-processed OLEDs will be elaborated, which are more competitive for mass production.

Title: Auditing and Smartness Evaluation of Building Automation and Control Systems
In future smart communities, buildings must possess energy efficient systems, provide absolute comfort, empower occupants with information, adapt operations to energy grid situations and facilitate strategic maintenance. A key condition to realize these deliverables, is a proper designed and well-equipped building automation and control system (BACS). This talk presents an innovative holistic tool ‘IBACSA’, for BACS assessment and smartness evaluation using a hybrid qualitative-quantitative multi-criteria approach. The tool serves as a comprehensive and user-friendly instrument in a systematic building initial and retro commissioning platform, ensuring a good start-up for newly built and retrofitted energy efficient buildings. First, the talk will highlight the importance of building commissioning and BACS auditing in improving the overall building stock operation and meeting environmental and energy goals. Then, IBACSA design and development will be presented, followed by live demonstration, considering three hospital buildings in Denmark.

Title: Energy for 21st Century and Beyond
Abstarct: Widespread industrialization, rapid urbanization, and massive transport through land, waters, and air have led to catastrophes such as climate change, water pollution, resource limitation, and pandemics causing severe economic consequences, massive influences on the natural environment and pose a great threat to the life sustainability. Energy generation and usage are one of the principal contributors of environmental adversity; therefore, radical changes are required to decarbonize the energy sector. Electron and hydrogen economies are widely discussed as sources to lower energy for their potential in lowering the carbon emission. Ironically, while these protocols can potentially reduce emission during operation, processing of materials to fabricate the devices to enable electron and hydrogen economies, such as electrical energy storage devices and fuel cells, are principal contributors of emission. Therefore, the decarbonization of energy sector is unlikely be accomplished without decarbonizing the materials production sector and demand low carbon materials. For example, current rechargeable batteries in two storage modes are commercial, viz. lithium-ion batteries (LIBs) and electrochemical capacitors (ECs; synonymously supercapacitors), with significantly differing performance indicators arising from the differences in their storage mode. Considering sustainability of electrical energy storage devices, ECs are preferred over batteries at least for two reasons. First is that the electrode materials in batteries are earthborn, which are mined and processed as specialty materials, the processing add significant amount of carbon emission. On the other hand, electrode materials of ECs could be sought from biomass; and therefore, are sustainable. Secondly, EC is a non-faradic ion adsorption process, thereby giving chargeability at any voltage. On the other hand, battery storage is via faradic reaction through either alloying or intercalation or redox reactions or their combinations, thereby requiring certain energies for charging. These two advantages make the ECs to be an intensive research topic recently. Similarly, the fuel cell and air battery performances are greatly influenced by the anode and cathode catalysts, which are most commonly sourced from novel metals or their alloys or their oxides and chalcogenides. This lecture addresses several issues to be solved for clean energy sector.
