Now that the panic over the coronavirus has plagued the entire world community, it has become clear that the progress of our civilization is in question - it either zigzags or we slide back into the caves.
A societal approach to a pandemic should be dealt with dynamic and complex issues via collaborative approaches. In order to develop problem-solving techniques, basic steps should be adopted through solution-oriented processes and methods.

Mixed oxide nanoparticles of iron and aluminium (FeAlO) were synthesized by combustion process and evaluated for the removal of chromium by adsorption from aqueous solution. The FeAlO were characterized for various physico-chemical properties using x ray diffraction, particle size, SEM, TEM, FTIR analysis. The adsorbent was evaluated to study the effect of different parameters like dose, pH and interference of other ion on removal efficiency. The data was fitted in Langmuir and Freundlich adsorption parameters were computed to determine adsorption capacity. The adsorption isotherm was best fitted for Freundlich adsorption model and adsorption capacity was 0.824mg g-1 for Cr (VI). The FeAlO has good potential for the removal of Cr(VI) from water and wastewater.

Facing the rage of nature appears to be unavoidable with its catastrophic impact on human life. However, every event is an opportunity to learn and set control measures to avoid or at least minimize the damage as much as possible. One of the most devastating natural phenomena is Tsunami. Pacific region is one of the most impacted areas in the world that is affected by this type of incident. A comprehensive record of southeastern islands in Hawaii was gathered as a comma-separated values file for measuring heights of Tsunami waves at coastal locations. The database was modified and stratified for trending and descriptive analysis using a unique approach through the statistical process control (SPC) platform. Quantitative analysis of the database showed Tsunami in 1946 was the strongest one with destructive waves striking most locations. Control charts for separate and averaged Tsunami incidences showed the average wave heights, upper tidal thresholds and excursions in the wave level in the recorded locations. Some preceding points before the apparently highest waves showed warning signals of tidal drift from the mean coastal Tsunami wave level. Fast, simple and inexpensive SPC methodologies can be used as a quantitative tool in crisis risk evaluation, decision-making and resources management.

Perovskite materials have become one of the hottest topics in solar energy conversion in recent years. They reached similar efficiency to the polycrystalline silicon solar cells, and also found applications in a variety of fields out of energy harvesting, such as lighting. The main advantage of this class of materials is the ease of processing, a line with the large-scale solution fabrication techniques. Although the technology still faces some challenges related to long-term stability the prospects for commercialization at the beginning of 2021 are much more realistic in comparison with the forecasts released at the end of the previous 2019 year. In this perspective articles analysis of the research and market perspectives of the perovskite solar cells is made.

The demand for new advanced functional materials has driven scientific work over the past decades. Nature has been inspiring in the creation of different types of self-cleaning and super repellent surfaces mimicking those of plants (lotus leaves), animals (shark skin) or insects (butterfly wings, water strider). To produce and maintain super repellent materials, chemical modification of the surface by using low surface energy materials such as fluoropolymers and/or siloxanes is necessary. Also, physical modification of surface roughness enhances super-repellency against various liquids. The surface roughness can be achieved e.g., by the deposition of nano particles (NPs) using Liquid Flame Spray (LFS). Industrial applications like paper coatings, oil-water separation, and microfluidic devices have benefited from the fabrication of super-hydrophobic surfaces by LFS. In our work, glass substrates were fluorinated by chemical vapor deposition (CVD) method, and others were additionally pre-coated with silica NPs by LFS. The coated glass surfaces were characterized for their anti-wettability by measuring the contact angles of water and compare that to bare glass. The influence of the produced coatings on the wettability of surface with different liquids was examined through measuring advancing/receding contact angles as well as the roll off angle. Results showed that compared to bare glass only fluorination of glass increased the water static contact angle from 18  to almost 112 . This is indicative of hydrophobic behaviour. Coating glass with silica NPs by LFS before fluorination, enhanced the water anti-wetting property for super hydrophobicity. LFS coating provided good oleophobic characteristic.
