“…No significant difference in the positions of the other peaks was found, indicating that the treatment of CFs only slightly affected the chemical composition. The same peaks were observed at 3450, 2300 -1 , 1650 -1 , and 1450 cm -1 , corresponding to -OH, C≡C, C=O, and-C-O, respectively [21,22]. The peak intensity of the treated CF increased significantly at 3450 and 1650 cm -1 , indicating an increase in the oxygencontaining functional group on the surface of CFs.…”

In this study, carbon fibers (CFs) were used as toughening materials to improve the mechanical properties of cement stone. The surfaces of the CFs were treated with concentrated nitric acid and sodium hypochlorite to increase the interfacial adhesion between the CFs and the cement. The CFs subjected to surface treatment were evaluated by scanning electron microscopy and infrared analysis to find a significant increase in the number of oxygen-containing groups on the surface. The CFs subjected to surface treatment were added to the cement matrix. The effect of the modified CFs on the mechanical properties of the cement matrix was evaluated by testing the means of mechanical properties. The maximum tensile strength, maximum compressive strength, and ultimate strain of the enhanced cement stone of the CFs treated with sodium hypochlorite increased by 68.2%, 12.0%, and 4.4%, respectively. The maximum tensile strength, maximum compressive strength, and ultimate strain of the enhanced cement stone of the CFs treated with concentrated nitric acid increased by 72.7%, 14.7%, and 4.5%, respectively. The addition of CFs to the cement stone exerted no effect on the type of cement hydration products, as determined by infrared analysis and X-ray diffraction. The toughening mechanism of the modified CFs added to the cement stone was ultimately explored, and the bridging effect, deflection effect, and pull-out effect of cracks were evaluated.

Pandemic is not a word to use lightly or carelessly. It is a word that, if misused, can reason difficult fear, or unwarranted acceptance that the fight is over, foremost to needless suffering and fatality. Coronavirus disease of 2019 (COVID-19) has become a deadly disease shaking the whole world. All the countries are facing a crisis in disposing of fast diagnostics of the syndrome, able to be organized to a wide number of persons. To control the spread of this virus harmful results of coronavirus have given rise to the growth of analysis tools. In this urgent situation, many researchers and scientists are working on finding a solution to control the deadly virus. In this chapter, we focused on researching biosensors that could detect the virus in the air. People breathe about 11,000 L of polluted air that is invisible. The major purpose of this sensor is, it could be used as another method and more significant to calculate the concentration of virus in the air, but it won't be the replacement for laboratory tests. Advanced technology, time-consuming and low-cost equipment for this disease spreading virus is in need to control the pandemic at the earliest. This biosensor is prevalent and can detect even minute amounts of viruses present in the air and surroundings.

“…It has been seen that their size can be constrained by observing its acid base balance, and temperature of the extract. Intracellular combination yields nanoparticles of littler size are also noted [28]. AgNO3 arrangement at 28 °C for 72 h was allowed to communicate which is separated from the Taxus plant with the organism (fungus), Verticillium sp.…”

In this modern era, (M/MO-NPs) Metal/metal oxide nanoparticles are utilized in various areas. The growth of nanoparticles is tremendous in our daily activities like beauty products, doses, delivery of drugs, and outfit. They can be set up by numerous strategies, for example, green amalgamation and the ordinary compound blend techniques. Green synthesis incorporates endless increase to deliver M/MO-NPs with requesting properties. In Bioengineering, the "green" combination has increased massive consideration as a trustworthy, dependable, and natural benevolent convention for orchestrating a wide scope of Nanomaterials including M/MO-NPs and bio propelled materials. Be that as it may, the utilization of plant extracts for this intention is profitable over organisms because of usability and less biohazard. Union of metal and MO-NPs by using the extract of plant fluid arrangement have increased consideration toward the green methodology and with no antagonistic impact on nature. The current article intends to survey the advancement made lately on nanoparticle biosynthesis by organisms. These microbial assets incorporate microorganisms, organisms, yeast, green growth, and viruses. This study predominantly centers on the biosynthesis of the most usually examined M/MO-NPs, for example, copper, cadmium, noble metals, platinum, titanium oxide, palladium, zinc oxide, and cadmium sulfide.
