Humidity sensor using surface adsorbed channel modulated Graphene nanoribbon: NEGF approach
Shakil, Shifur Rahman; Zohra, Fatema Tuz; Pramanik, Parna; Tushar, Raihanul Islam
Electronic transport properties of Graphene nanoribbon (GNR) are explored by self-consistent numerical simulation. The effects of vapour (H2O) adsorption in GNR sheets on its current-voltage (I-V) characteristics, conductivity, electrostatic difference potential and device density of states were studied with necessary physical insight. We found that conductivity of GNR sheet increases in some particular energy range with the increase in number of H2O molecules adsorbed. Then we encounter the effects of metal-GNR contact to investigate the practical performance of GNR as a medium of humidity sensing. Later we propose a simple schematic model for GNR Humidity Sensor (GNRHS) to investigate its performance in applied regime.

Propasal of possible OTEC sites in Bangladesh
Shakil, Shifur Rahman; Hossain, Md. Safwat; Rouf, Nirjhor Tahmidur
Bangladesh, a new name among the fast developing country, has a huge population of more than 160 Million people and a large demand for electricity. Although Bangladesh is still struggling to provide a stable energy source to the growing industrial sectors and general mass, the geographical location of this country is very advantageous for the development of renewable energy. The site of Bangladesh is naturally gifted area to establish alternate energy collection sources like Ocean Thermal Energy Conversion (OTEC). Since Bangladesh lies just beneath the tropic of cancer and on the shore of the Bay of Bengal, the two vital elements: constant sunlight and large littoral areas needed for OTEC can easily be found in this region. With huge water bodies throughout, this zone is very much suitable for developing multiple OTEC plant size.

Proposal for introduction of ocean thermal energy conversion (OTEC) to the energy sector of Bangladesh
Shakil, Shifur Rahman; Hoque, Md. Anamul
Bangladesh is among the worst victims of the global energy crisis, but it is also in one of the most advantageous positions to make transition towards the renewable energy path. In order to solve the power crisis problem by introducing innovative renewable technologies, this paper proposes and analyses the factors behind OTEC technology establishment in Bangladesh. The main objective of this paper is to propose and present the need to set up this new cleaner and efficient source of renewable energy by analyzing its suitability on geographical position. The site of Bangladesh is naturally gifted area to establish Ocean Thermal Energy Conversion (OTEC) as Bangladesh lies just beneath the tropic of cancer and on the shore of the Bay of Bengal, the two vital elements: constant sunlight and large littoral areas needed for OTEC can easily be found in this region.

Exploring modular architecture for nano satellite and opportunity for developing countries

SPACE Technology has the potential to provide information, infrastructure and inspiration that meets national needs in developing countries like Bangladesh. Many countries recognize this; in response they are investing in new national satellite programs to harness satellite services. Technology related to space is one example of a tool that can contribute to development both by addressing societal challenges and by advancing a nation's technological capability. To cope up with the advanced world in space technology Bangladesh seems to be highly potential country for satellite, Robotics, embedded systems and renewable energy research. BRAC University, Bangladesh is planning to launch a nano satellite with the collaboration of KIT, Japan. The proposed nano satellite project mission is to experiment about social, commercial and agricultural survey needs in Bangladesh. Each of the proposed applications of the project will improve the lives of millions of people of Bangladesh and it will be a pathfinder mission for the people of this country. Another intention of this project is to create a cheap satellite based remote sensing for developing countries as the idea of large space systems is very costly for us therefore we have decided to make a Nano-satellite.
