Abstract:
Polymer Electrolyte Membrane Fuel Cell (PEMFC), an electrochemical power generating technology, uses a precious metal Platinum (Pt) catalyst for Oxygen Reduction Reaction (ORR), which is a major hindrance in its commercialization. Using a non-precious group metal (NPGM) instead of Pt will reduces the cost of PEMFCs. Herein MnO2 carbon nanotubes (CNTs) were synthesized by impregnating the transition metal in large surface carbonaceous material CNTs by hydrothermal synthesis techniques. To enhance the catalytic reaction and increase the volumetric current density, the sample was pyrolyzed at 800 0C temperature under nitrogen atmosphere. During pyrolysis, the nitrogen was also doped in the framework of carbonaceous materials. The materials were then treated with acid, removing the unreacted metals and adding oxygen functional group to the CNT framework due to which the activity of the catalyst is amplified. The catalysts have been characterized by scanning electron microscope (SEM), Xray diffraction (XRD), Catalyst activity has been calculated by Rotating Disc Electrode (RDE) experiment. The resulting materials are stronger in experimental conditions in alkaline environment and have high electro catalytic activity for oxygen reduction reaction (ORR). Linear Sweep Voltammetry (LSV) depicts a current density of - 4.0 mA/cm2 and over potential of -0.3V vs. Standard Calomel Electrode (SCE) in 0.1M KOH electrolyte. Rotating Disk Electrode (RDE) was conducted at 400, 800, 1200, and 1600 rpm. The results of MnO2CNT are expected to be desirable in fuel cell commercialization.

Abstract:
A passive liquid feed Direct Methanol Fuel Cell ( DMFC ) was fabricated using given MEA ( Membrane Electrode Assembly ) and tested for different current collector structure. Mesh current collectors of different mesh densities along with different support structures were used and the performance was found to be better. Methanol concentration was also varied. Optimisation of mesh size, support structure and fuel concentration was achieved. Cost analysis was also performed for the different configurations of the Direct Methanol Fuel Cell which indicates that the mesh current collectors are always beneficial to be used in this fuel cell. From the performance analysis study of Direct Methanol Fuel Cell we can conclude about the following points : • Area Specific Resistance (ASR) of wiremesh current collectors compared to that of stainless steel current collectors. Also, the voltage-current ( V-I ) & power - current ( P-I ) characteristics & their trends using wiremesh current collectors as compared to that of the stainless steel current collectors configuration. • Supporting & strengthening structures’ vital role determination & validation in wiremesh current collectors configuration. • Voltage-current ( V-I ) & power - current ( P-I ) characteristics & their trends for the different wiremesh open area density of current collectors. •Voltage-current ( V-I ) & power - current ( P-I ) characteristics & their trends for the different wiremesh open area density of current collectors operating at different methanol concentrations. •Methanol concentration optimization for better and stable Direct Methanol Fuel Cell performance. Cost analytics for both the configurations i.e. Stainless steel current collectors configuration & wiremesh current collectors configuration. Its optimization to achieve the flexibility, light weight structure & compact size in wiremesh current collectors configuration.

Abstract:
It has been demonstrated during the last decade that radiative transfer could be significantly enhanced when the distance between two objects is smaller than the characteristic thermal wavelength due to photon tunneling or coupling of evanescent waves. In particular, the near-field radiative flux could far exceed the blackbody limit by the coupling of additional resonance modes. On the other hand, similar to photovoltaic panel, the thermophotovoltaic (TPV) energy conversion system, which consists of two main components of thermal emitter and TPV cell, is also a direct energy conversion process from heat to electricity through electron–hole pair generation from absorbed thermal radiation. The advantages of TPV systems include versatile thermal sources and high conversion efficiency potential, which makes it an important component of renewable energy conversion, while the power output and conversion efficiency achieved are still very low currently. However, the greatly enhanced radiative heat transfer in near field provides the possibility to improve power output and conversion efficiency of current TPV systems, and a near-field TPV system has been rapidly developed for the past decade. In this talk, we will firstly introduce some additional resonance modes to further enhance radiative heat transfer in near field, including commonly used surface plasmon/phonon polariton [1], recently developed hyperbolic modes [2], metamaterial based ones [2,3], and magnetic polariton [4,5], which was firstly discovered by us recently. Taking advantage of these mechanisms in enhancing near field radiative heat transfer, we also improved the power output and conversion efficiency of a near-field TPV system by carefully designing metamaterial based thermal emitters, like multilayer structure [6], nanowire based one [7], and nano gratings [8]. To summarize, combining the advantages of both metamaterial based thermal emitter and enhanced radiation in near field would benefit a lot for improving the performance of TPV energy conversion, and we hope this talk could provide some hints on this direction.

Title: Renewable Energy Output in Africa
Biography:
Completed University of Cape Coast (2007) with a Bachelors Degree in Economics. Worked with Standard Chartered Bank (Ghana) for almost Two years as Technical Support Specialist. And in 2017, I decided to get back into academia for my Master degree in Economics and Start a PhD in Environmental economics right afterwards. Currently, my paper “Trade liberalization and food balance sheet in Africa” has been accepted for publication in a book series. “Encyclopeadia of the UN Sustainable Development Goals. I have also submitted another paper Renwable energy consumption in Africa: Evidence from corrected least squares dummy variable to a peer review journal “Renewable Energy”
Abstract:
In most Sub Saharan African countries renewable energy has been part of the energy mix balance-sheet for quite a long time. However, the share of total primary energy from renewable sources have declined over time despite significant investment into the sector in the last decade. This paper pierce the veil of the energy sector to unearth the underlying factors driving renewable energy output in the region using a panel data of 32 SSA countries from 1990 to 2015. Using a novel estimator (Regression with Driscoll-Kraay standard errors) that is robust to serial correlation and cross-sectional dependence. Findings from the study point to the underlying factors of renewable energy in Co2 emissions per capita, income per capita, oil prices, trade openness, natural resource rents, urbanization, population growth rate, and climatic stress. The study proposes policies that incorporates environmental awareness in the national development plans of countries; increasing renewable energy consumption among the middle class; encourage regional renewable energy grid sharing; implementing and expanding the feed-in-tariff system; and granting tax incentives to companies that seek to invest and develop the renewable energy sector in the region.

Abstract:
The aim of presentation consist of renewable energy, resources, health, life, employment, income, economy poverty and hunger were studied and reported that Renewable Energy and Resources is the major industry for the development of health, basic need of daily life, create employment, generate income, stronger economy, reducing financial crises, global Poverty and hunger in the developing countries of the world particularly in south Asia. Renewable Energy means all forms of energy produce from the renewable sources. The major sources of renewable energy like biomass, hydropower, solar, wind, geothermal and ocean. In other word, energy derived from natural process such as sunlight, wind, rain, tides, redaction and other natural elements with the sustainable yield are called renewable energy. Renewable energy and wind are the basic need of our life. Look at the universe, no activity is found without the use of energy. You name any action in the world, you will find the force of energy behind it. As reported, major sources of renewable energy and wind are the cheapest source of electricity but the two main problems in the developing nations that is densely population of 5.87 billion amongst the world population of 7.84 billion and concentration on non-renewable energy which are very costly although a great potential of renewable energy and wind are available. According to World Bank, about 1.4 billon peoples lack electricity in the world and nearly one billion peoples in the developing nations like South Asia go to bed hungry each night. It means, renewable energy and resources are the main substitute of poverty, increase agricultural and industry production, create employment, generate income as well as decreasing energy crises, which will reduce the global poverty and hunger in the developing nation of the world like South Asia.
