    Abstract The declaration of COVID 19 as pandemic has impacted the society at large. In what started with 17 cases in Wuhan spread its tentacles and has now over 4 million cases across the globe. In this rapidly changing environment, it is extremely difficult to quantify the impacts that the virus has on many aspects of society. The paper highlights the various challenges and the impact on society, economy and general health. These are only initial levels impacts, and it goes on with greater implications on growth depends on many factors, including the social distancing norms and shutdown rules laid by countries. Nonetheless, it is clear that the virus is here to stay and is likely to impact growth, health and society substantially.

    Abstract Worldwide significant efforts are ongoing to develop devices that store solar energy as fuels. In one such approach, solar energy is absorbed by semiconductors and utilized directly by catalysts at their surfaces to split water into H2 and O2. To protect the semiconductors in these photo-electrochemical cells (PEC) from corrosion, frequently thin TiO2 interlayers are applied. Employing a well-performing photoanode comprised of 1-D n-Si microwires (MWs) covered with a mesoporous (mp) TiO2 interlayer fabricated by solution processing and functionalized with α-Fe2O3 nanorods, we studied here the function of this TiO2 interlayer by high-energy resolution fluorescence detected X-ray absorption near edge structure (HERFD-XANES) spectroscopy, along with X-ray emission spectroscopy (XES) and standard characterization techniques. Our data reveal that the TiO2 interlayer not only protects the n-Si MW surface from corrosion, but that it also acts as a template for the hydrothermal growth of α-Fe2O3 nanorods and improves the photocatalytic efficiency. We show that the latter effect correlates with the presence of stable oxygen vacancies at the interface between mp-TiO2 and α-Fe2O3, which act as electron traps and thereby substantially reduce the charge recombination rate at the hematite surface.

    Abstract The novel coronavirus or COVID-19 has extended its spread across the globe, and most of the countries have reported infections. In what started as a first case single reported in Egypt has now magnified and close to about 355000+ infections have been reported across the African region as on 26-6-2020. The transmission trajectory of COVID-19 across the globe remains a mystery, and much remains to be learned. The fear of spread among nations is a cause for concern, especially among African countries with weaker governance, high poverty levels, weak health systems etc. The density of population in urban areas could be a trigger factor and could be devastating. The management and control of COVID-19 are critical to check the spread, and most of it is reliant on the health facilities in countries to carryout repeated tests. This paper aims to analyses the various parameters and tabulates a risk matrix and places it analysis using SPSS based on the available data. The analysis also provides potential insight into the vulnerabilities among African countries and a relative review of factors associated with the novel coronavirus.

    Abstract The growth of renewable energy technologies as an alternative source of power is a great boon to the rural masses where energy is predominantly a challenge. This paper focuses on studying the microeconomic benefits of the virtual power plant as a solution to the rural masses who either have no access to energy or has limited access. The model here uses HOMER as a tool for modelling the design. The simulation results discuss the profitability of the virtual power plant as a solution not only to the virtual power plant operator but also to the rural households while ensuring a sustainable income source with the use of solar power PV as a generator.

    Abstract Improving interfacial contact between each component in the proton exchange membrane fuel cell (PEMFC) can lead to a significant increase in power density and Pt utilization. In this work, the junction between the catalyst layer and gas diffusion layer (GDL) is greatly enhanced through direct attachment of helical carbon nanofibers, giving rise to a hierarchical structure within the electrical interconnections. The alternative novel GDL is produced by spraying a thin layer of Pd

    Abstract Herein, we communicate about an Earth-abundant semiconductor photocathode (p-Si/TiO2/NiOx) as an alternative for the rare and expensive Pt as a counter electrode for overall photoelectrochemical water splitting. The proposed photoelectrochemical (PEC) water-splitting device mimics the "Z"-scheme observed in natural photosynthesis by combining two photoelectrodes in a parallel-illumination mode. A nearly 60% increase in the photocurrent density (Jph) for pristine α-Fe2O3 and a 77% increase in the applied bias photocurrent efficiency (ABPE) were achieved by replacing the conventionally used Pt cathode with an efficient, cost effective p-Si/TiO2/NiOx photocathode under parallel illumination. The resulting photocurrent density of 1.26 mA cm-2 at 1.23VRHE represents a new record performance for hydrothermally grown pristine α-Fe2O3 nanorod photoanodes in combination with a photocathode, which opens the prospect for further improvement by doping α-Fe2O3 or by its decoration with co-catalysts. Electrochemical impedance spectroscopy measurements suggest that this significant performance increase is due to the enhancement of the space-charge field in α-Fe2O3.
