Prof. Anping Wang et al., with his research collaborative team from china ( 1. Guizhou University, China; and 2. Guizhou Normal University, China) and India (National Chemical Laboratory, India) have reviewed the research over views on the preparation methods, physicochemical properties, stabilization/functionalization, and the catalytic applications of magnetic materials, including magnetic acids, bases, enzymes, and acid-base bifunctional materials for the synthesis of bio-diesel. Here, we discuss only the preparation of efficient bio-diesel with merits and applications of magnetic nanocatalyst for the bio-diesel preparation . Bio-diesel products are mainly attain from bio mass feed stocks, which gives more attention in the biorefinery research affairs [1]. A green way of renewable liquid biofuels are emergency required one in present atmosphere. Among the various classes, best one is renewable diesel fuel, the chemical content of long-chain fatty acid methyl ester (FAME) or ethy

Prof. Jiang  et al ., from (1 . Research Center for Eco-environmental Sciences, Chinese Academy of Sciences, Beijing, China; 2 . University of Chinese Academy of Sciences, Beijing, China, 3 . Institute of Environmental and Ecological Engineering, Guangdong University of Technology, Guangzhou, China ) and their research collaboration team have reported on the single-atom Fe(III)- and nitrogen doped carbon (Fe−N−C) which can efficiently activate peroxydisulfate (PDS) to selectively remove some organic pollutants following an unreported nonradical pathway. Generally, PDS is used as an oxidant for the degradation of polluted water/soil, it generates sulfate radical intermediate for the degradation pollutants, and this radical unselectively reacts with most of the substances in water/soil. PDS can be activated by base, heat, UV, low valent transition metal ions (e.g., Co 2+, Fe 2+, Cu 2+, and Ag + ), and zero valent iron to produce a sulfate radical (SO 4 •− ). All these PDS activation pro

Tokyo University of Science, Kagulazaka 1-3, Shinjuku, Tokyo 162-0825, Japan)  and their research collaboration team have discovered hierarchical Sn and AgCl co-doped TiO 2 microspheres as an electron transport layer for the enhanced perovskite solar cell performance.   Zero carbon emission by low-cost and environmentally-friendly alternative energy resources is required for the growing world’s energy demand. Concerning this, perovskite solar cells (PSCs) have gained more attention in recent years, owing to their low cost, higher absorption coefficient, and high efficiency

Let us start with David Frederick Attenborough, who is an English BBC broadcaster  and  natural historian . In 2019, he also received Landscape Institute  Medal for Lifetime Achievement and Landscape Institute Honorary Fellow (HonFLI). He mentioned about the global climate impact as follows: “It may sound frightening, but the scientific evidence is that if we have not taken dramatic action within the next decade, we could face irreversible damage to the natural world and the collapse of our societies”.                                         ---  Attenborough, Our Planet Scientific experts and researchers are under monitoring and providing the global climate context to the crisis, including:  Dr. James Hansen , NASA Goddard Institute for Science Studies  Professor Naomi Oreskes , Harvard University  Richard Black , UK Energy and Climate Intelligence Unit  Sunita Narain , India’s Centre for Science and Environment  Professor Michael Mann , Penn State University  Professor Andrew Shephe

Scientists from Various Universities ( Department of Mechanical Engineering, School of Engineering and Applied Sciences, University of Rochester, Rochester, NY, USA, Department of Physics and Astronomy, University of Rochester, Rochester, NY, USA, Intel Corporation, Hillsboro, OR, USA, Department of Chemistry and Biochemistry, University of Nevada Las Vegas, Las Vegas, NV, USA, Department of Physics and Astronomy, University of Nevada Las Vegas, Las Vegas, NV, USA ) and their research collaboration team have discovered a mystery material that conducts electricity without any resistance at a room temperature of up to 15 °C. It is a new record for superconductivity, a phenomenal effect which is usually operated at very cold temperatures. As per the discovery in 2015, the material itself shows the potential of a class of superconductors. Over the past decades, there was an emerging interest in the discovery of materials relevant to room-temperature superconductivity mainly for the produc

Prof. Lahiru A. Wijenayaka, Sri Lanka Institute of Nanotechnology (SLINTEC), Mahenwatte, Pitipana, Homagama, Sri Lanka and his collaboration team has reported on the interesting materials for effective environmental alternative remediation via nontoxic, low cost and eco-friendly methods dedicated to the scientific community. Here, a novel, facile, and green synthetic approach to synthesize gold nanoparticle decorated over TiO 2 (Au/TiO 2 ) nanocomposites for sustainable environmental development has been discussed [ 1 ] . Based on various metal oxide semiconductor (MOS) photocatalysts, titanium dioxide (TiO 2 ) is the most widely used, owing to its effective and excellent results in optical transmittance, high refractive index, chemical stability, concurrently being stable, nontoxic, and inexpensive [ 2 ]. They are highlighted with the following points: (i) Synthesis of the Au/TiO 2 nanocomposite, (ii) Microscopic characterization, (iii) Dye adsorption on Au/TiO 2 and (iv) Photoca

According to the Food and Agriculture Organization of the United Nations (FAO UN), Hunger Report, Ending hunger is a major objective of the United Nations’ (UN) Sustainable Development Goals (SDG), hunger is the term used to define periods when populations are experiencing severe food insecurity - means that they go for entire days without eating due to lack of money, lack of access to food, or other resources [ 1 ]. Hunger is strongly interconnected with poverty, and it involves interactions among an array of social, political, demographic, and societal factors. An attention is must in the following topics to put an end card for poor hunger:  Global Hunger Index (GHI). World Food Program’s 2020. Global Report on Food Crises.   Smallholder-farming. Ceres2030. The two main international institutions are the International Institute for Sustainable Development (IISD) and the International Food Policy Research Institute (IFPRI) , joined forces to estimate what it would cost to end hunge
