Biological and Non-Conventional Synthesis of Zinc Oxide Nanoparticles (ZnO-NPs): Their Potential Applications

Bhabesh Deka, Chittaranjan Baruah, Azariah Babu, Pankaj Kalita

In nature, nanoparticles can be found as natural or synthetic. Nanoparticles may form either physically or chemically. Nanoparticles are uniform types of common material whose dimensions are less than 100 nm. Volcanic ash, ocean spray, fine sand, and dust are some examples of natural nanoparticles.

Photocatalytic Degradation of Organic Dyes Using Titanium Dioxide (TiO2) and Mg-TiO2 Nanoparticles

Sandesh Jaybhaye, Nikita Shinde, Shrutika Jaybhaye, Himanshu Narayan

Titanium dioxide (TiO2 ) based nano-sized photocatalysts (NPCs) were synthesized following a green method from the extract of Peepal (Ficus religiosa) leaves and titanium tetrachloride as precursors. Doping of TiO2 with Magnesium (Mg) was done using magnesium chloride through the method of chemical precipitation. Size of the NPC samples were estimated and characterized by CPS Disc Centrifuge, Diffracted Light Scattering (DLS) and Field Emission Gun Scanning Electron Microscopy (FEG-SEM) techniques.

Detection of Viruses and Development of New treatments: Insights into Antibody-Antigen Interactions and Multifunctional Lab-On-Particle for SARS CoV-2

Martin Amé, Esraa Samy Abu Serea, Ahmed Esmail Shalan, A. Guillermo Bracamonte

The Corona Virus disease is a severe respiratory problem generated via severe acute respiratory syndrome coronavirus 2 (SARS CoV-2). The latest strain of the disease was deadly enough to halt the global routines of human development. In this context, a number of research studies have been conducted to provide knowledge and to combat with this severe illness.

Nanotechnology in Water Treatment: An Optimistic Perspective for the Near Future

Bruna Maria Praun Pereira, Bianca Pizzorno Backx

Unequal access to drinking water and basic sanitation are old issues in Brazil and worldwide. Besides, this situation foments the proliferation of infectious parasitic diseases. Moreover, mainly in underdeveloped countries, it victimizes socioeconomically vulnerable people. The degree of water contamination analysis, usually by fecal matter, is made by the number of microorganisms present in the sample, including Escherichia coli or thermotolerant coliforms. In addition, several

At the end of 2019, a novel severe respiratory disease (coronavirus disease 2019, COVID-19) spread to Wuhan, China, it became pandemic in few months, with more than 41 million people infected worldwide as of October 2020. COVID-19 is caused by a novel virus called severe acute respiratory syndrome (SARS) CoV-2 to distinguish it from SARS-CoV that emerged in Guangdong province in China in 2003 and caused the severe clinical condition known as SARS. Like SARS-CoV, SARS- CoV-2 causes a severe inter

Green Nanotechnology: The Influence of Intermolecular and Supramolecular Interactions

Otávio Augusto Leitão dos Santos, Bianca Pizzorno Backx

In the last decade, the study of nanometer-scale particles has grown exponentially worldwide. This growth is due to the broad field of nanostructures applications, which, due to their dimensions in nanometric sizes, have new properties not found in micro and macro scale. These properties result from the increase in the ratio between the surface area and volume, and the nanostructures’ size directly influences these. Tolerance to temperature, variety of colors, changes in chemical reactivity,

Current Progress in Vanadium Oxide Nanostructures and Its Composites as Supercapacitor Electrodes

Raktima Basu, Sandip Dhara

In recent time, supercapacitors (SCs) are one of the emerging technologies used for clean energy prospect. The higher power density, low specific energy, longer cycle life, and environmental affability made the SCs superior compared to conventional batteries. However, the scientific community is working towards increasing the specific energy of SCs by finding a suitable electrode material. Carbon materials, conducting polymers, and metal oxide or hydroxides are

Reducing the size of a metal from macroscopic to the nanoscale generates a scaling behavior in physical and chemical properties due to the large surface-to-volume fraction. While a further size reduction to small clusters under 2 nm (<~100 atoms) yield geometric and electronic structurwhich are still different from their nanoparticle (NP) counterpart.
