This lecture explains what carbonization is, addresses its causes and impacts. It then offers technological solutions to reduce CO2 emissions from the electric power sector which is responsible over 30% of global Carbon emissions. In order to address the reduction of carbon emissions from the electric power sector, a collaborative approach between the industrialized nation states and emerging economies is necessary. This will involve a portfolio of solutions with low-carbon generation from wind, solar, hydro and nuclear, storage, cross-border power transfer and advanced technology focusing on energy efficiency. This talk also discusses the IEEE Climate Change program and related activities.

We review recent research in various types of optical quantum computing using liquid crystal devices. First, we have investigated Young's Interference experiment using self-aligned liquid crystal (LC) devices and a logical "NOT" operation is achieved. Second, numerical quantization of interfering small photons using a LC retarder is investigated. Third, a Mach-Zehnder interferometer with an optical phase control by a twisted nematic (TN) LC device was studied. Fourth, a basic experiment on 2-bit quantum calculations related to the Deutsch-Jozsa algorithm on a linear optical quantum computer using the LC device as a linear optical element was investigated.

Amid imminent conventional fuel crisis, electrical energy supply may face serious consequences in many developing countries, including Bangladesh. Many developed nations have already aligned themselves towards alternatives to fossil fuels in their long-term energy roadmap, attributing to the tremendous development of renewable energy resources especially solar photovoltaic energy technologies. Over the past few decades, solar energy in the form of solar photovoltaics (PV) has demonstrated to be the most potential renewable energy resource to date. The cost-efficiency has become praiseworthy whereby $/Wp cost of solar PV products or LCoE have reduced tremendously with many consumer-friendly policies around the world. Since ‘90s we have been using solar panel systems with the then-given warranty of around 25 years. Now, time has come in many countries to think about recycling or end-of-life management. The talk will introduce recent trends of solar PV home and abroad as well as some of the prominent technologies of solar panels’ end-of-life management in the hope that Bangladesh can also step into a new industrial sector ahead of many other nations. This is to encourage our stakeholders to get ready for future endeavors towards a new industrial frontier of solar PV energy application.

Infrared (IR) detectors play a significant role in a wide range of applications such as military use, surveillance, medical diagnostics, remote sensing, space exploration, nondestructive inspections and scientific research involving spectrometers and radiometers. Since the 1950s, a variety of materials and technologies have been developed for IR detection. A microbolometer is a class of IR detector in which the resistance changes with change in temperature because of absorption in the IR regions. While Various vanadium oxide and amorphous silicon are two of the most commonly used materials for microbolometers, they suffer from low absorption in the wavelengths of interest. In this context Sn doped GexSi1-xOy film was investigated for desired electrical and optical properties for using them as NIR (SWIR) and mid IR sensor. In this talk I will present the electrical, optical and thermal properties such as variations of resistance with temperature, TCR, activation energy, electrical noise, thermal conductivity, and variations of transmittance, reflectance and absorption, optical constants (n, k, and ) with wavelengths of the Sn doped Ge-Si-O alloys for use in microbolometers.

Dr. Rajan Kapur started his career at AT&T Bell Labs. Since 1985 he has worked exclusively with start-ups, first with micro-chips in the Silicon Valley, and then micro-displays in Colorado. In 2006, he transitioned to renewable energy and founded a solar micro-inverter company that he later sold. Since then, he has run a sustainability incubator in his garage in Colorado, working with small dispersed teams on early-stage projects, with participants from the US and abroad.. In the leadership team at IEEE Smart Village, an all-volunteer humanitarian seed-fund cum incubator, he works with five regional groups in underserved regions around the world. They leverage renewal enegry and the productive use of technologies, education and enterprise to improve livelihoods. They address climate change through the electrification of underserved economies. Current enterprises include Solar smart irrigation in India, gem-stone cutting in Zambia, electrification to combat deforestation in Argentina, peri-urban aquaculture in Malawi and India, Solar animal farming in China, etc. Working with Rotary International, IEEE Smart Village has funded telehealth projects in Uganda and Kenya. Under his leadership, they have started “vocational awareness” initiatives for children to better prepare for a more electrified future. Dr. Kapur is the holder of five issued US patents. He holds Electrical Engineering degrees from the Indian Institute of Technology, Kanpur; Rice University, Houston and the University of Texas at Austin.
