A group of researchers and their team (Zhao et al .) from various Universities ( Tsinghua University, China, Southeast University, China, Columbia University, New York, Imperial College London, and The Ohio State University, USA) have surveyed a review on biomass-based chemical loops, its good, bad, and future aspects. Zhao et al ., have discussed the biomass, which is considered to be one of a promising renewable energy resource owing to its high moisture content, low energy density, and complex ash components. Biomass is a major energy source, it is considered to be a carbon-neutral renewable and abundant energy resource. The use of carbon in biomass for energy production, which was obtained from atmospheric CO 2 , is considered to be a carbon-neutral fuel. When this biomass is combined with carbon capture technology, then the overall energy conversion progress will be in negative in terms of net CO 2 emission, which is to be termed as BECCS (bioenergy with carbon capture and stora

The term “Bionic Eye” referes to a device to help the blind who lost their vision due to diseases like retinitis pigmentosa or macular degeneration. Prof. Jeffrey V. Rosenfeld, (Senior Neurosurgeon, Alfred Hospital and Professor of Surgery, Monash University), and his team has reported on the effective bionic vision results with his team. New development of “Bionic Eye”, using a brain prosthesis, wireless device interface with brain response. Figure 1. Schematic of cortical vision prosthesis system in bionic eye   [1] . The technical word ‘bionic’ was pointed by Maj. Jack E. Steele (1958), Air Force - US. Bionic is an interdisciplinary sharable word from life science ( bio logy) and engineer science (electro nics ) sectors. Engineers have created a new device to support physically challenged people do chores like normal people [2] . In 1970, Bionic was famous with TV series by “The Bionic Woman” and “The Six Million Dollar Man”, highlighted about the various super human intelligen

 Beijing University of Science and Technology researchers and their team (Huang et al.) have surveyed the synthesis of nanoporous perovskite metal oxides and their applications. They discussed various synthesis methods for the preparation-nanoporous perovskite metal oxides and used it for various useful applications. In general Perovskite metal oxides (ABX 3 ), here A-site is an alkaline, earth-alkaline or lanthanide element and B-site preferably with a transition metal. ABX 3 structure tolerates very large distortion with respect to the ideal cubic symmetry and X = O, Cl, Br, F (ex: CaTiO 3 ). Among the f ive compositional flexibilities of ABO 3 , the major response in experimental and predicted (theoretical) reports are done in (A 1+ B 5+ O 3 ), (A 2+ B 4+ O 3 ), and (A 3+ B 3+ O 3 ), In reality, of the 2346 kinds of possible ABO 3 composition only about 265 have been obtained experimentally [ 1 ]. Tolerance factor and stability are playing a vital role in their application scen

  Face masks have become a part of many people's everyday wardrobe due to the  coronavirus  pandemic. Researchers, designers, and everyday people have shown their imagination and creativity by turning face masks into art projects and expressions of identity.  While the work on the COVID-19 vaccine is still in progress, people have advised to maintain social distance, personal hygiene in public places, in addition, to mandatorily wear face masks all-the-time outside of the home. Coronavirus disease (COVID-19) is an infectious disease caused by a newly discovered coronavirus. Most of our peoples are infected due to COVID-19, they will experience mild to moderate respiratory illness and recover without requiring special treatment. The coronavirus spreads primarily through droplets of saliva or discharge from the nose when an infected person coughs or sneezes, speaks, and sings [ 1 ]. Older people and those with underlying medical problems like cardiovascular disease, diabetes, chron

Metal Organic Frameworks (MOFs) are constructed by metal ions/clusters and multidentate organic linkers via coordination bonds (reticular synthesis) have significantly enriched the domain of porous materials [ 1 , 2 ]. Based on the flexibility of the constituents, geometry, size and functionality, MOFs with a crystalline nature possess extremely high surface areas (typically ranging from 1000 to 10,000 m 2 g -1 ) and tunable pore sizes/characteristics. These aspects endow MOFs with fantastic functionalities/properties for a variety of applications such as gas adsorption, separation, catalysis, sensors, drug delivery, proton conduction etc [ 2 ]. In the de novo synthesis of MOFs, ligands with relatively high pKa (e.g. azoles) easily produce robust frameworks with low-valent metal ions, while linkers with relatively low pKa (e.g. carboxylic acids) tend to bind with high-valent metal ions to give stable structures. In general, dense and rigid frameworks are constructed by rigid and h

  The trend of exploring new sources of fuel for automobiles is increasing over the past decade, where the use of biodiesel as alternatives for fossil fuels is investigated exclusively, due to its potential of decreasing greenhouse gas and air pollutant emissions. Production and use of biodiesel can encourage the agricultural industry and provide self-reliance on automobile fuels which in turn boosts regional economic development. Biofuels or biodiesel is widely used as hybrid fuel in more than 20 countries around the world with an account annual consumption of over 2 million tons  [ 1 ] .  Figure 1. Credit to SNB. As an example in this context, considering the Hong Kong region, the increasing interest among the public to reduce air pollution drives them to use biodiesel as fuels. The environmental protection department of Hong Kong has conducted a feasibility study at the University of Hong Kong on the use of biodiesel as an automotive fuel in Hong Kong. The main motivation and goal o
