Biosynthesis of Manganese Dioxide Nanoparticles and Optimization of Reaction Variables

Abelneh Terefe Mekuria

Biosynthesis is an efficient and environmentally friendly process used to synthesize nanoparticles. This study presents a simple, environmentally friendly, and cost-effective method for synthesizing manganese dioxide nanoparticles from aqueous manganese (II) acetate using lemon extract as a reducing agent. Turmeric extract (curcumin) was employed to stabilize the biosynthesized nanoparticles. UV-visible spectroscopy was used to evaluate the concentration of nanoparticles at 350 nm wavelength.

The Effect of Nano-Encapsulated Orlistat on Prostate Cancer: An In vitro Study

Ferah Armutcu, Bahattin Adam

Background: The targeted inhibition of fatty acid synthase (FASN) by Orlistat, a potent FASN inhibitor, has been shown to block tumor proliferation and induce apoptosis in cultured tumor cells. Since Orlistat is insoluble, its solubility in blood circulation is limited. Cancer nanotherapeutics are rapidly progressing and are being implemented to solve several limitations of conventional drug delivery systems.

How to Compare and Select Flame Retardants for Rigid Polyurethane Foam

Ya Xuan Thong, Xiaodong Li, Xi Jiang Yin

Polyurethane (PU) foam is synthesised via a polymerisation reaction of polyol and isocyanate, in the presence of various formulations of catalysts and surfactants. For this reason, depending on the composition, PU foam can be tailor-made into flexible foams, semi-rigid foams, and/or rigid foams, resulting in a wide range of products with unique properties.

Nanotechnology for Water Purification – Current Trends and Challenges

M. P. Ajith, Paulraj Rajamani

Environmental pollution is a significant concern in both developing and developed countries. The pollution load in the environment accumulates as a result of anthropogenic activity. Both organic and inorganic contaminants are hazardous to living things, and their incidence and persistence have risen dramatically in current years.

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,

Multidirectional Benefits of Nanotechnology in the Diagnosis, Treatment and Prevention of Tuberculosis

Monika Gupta, Shivangi, Laxman S. Meena

Despite the curious advancement in medical science and therapeutics, tuberculosis (TB) persist the primary factor of mortality than any other infectious disease and socioeconomic disaster for millions of people around the world. According to the World Health Organization (WHO), World’s One-third of the population is infected with this disease and of these, 8 to 10 million people develop active disease and 2 million people die each year and the rest of the infected people remain asymptomatic.

Exploiting Nanotechnology to Target Viruses

Sérgio Antunes Filho, Otávio Augusto Leitão dos Santos, Mayara Santana dos Santos, Bianca Pizzorno Backx

Infectious diseases caused by microorganisms of the most varied natures and by viral entities cause millions of deaths every year. Around the world, viral infections have impacted civilizations’ circumstances since the earliest times, including the current panorama of the SARS-CoV-2 pandemic known as coronavirus disease in 2019 (COVID-19). In this sense, in the last century,

Development of Metal Oxide Nanoparticles as Semiconductors

Ahmed M. Abu-Dief

The variety of methods employed during the fabrication of MONPs can alter the characteristics and control the properties of the obtained nano-oxides. The reaction mechanisms and, therefore, the functionality of nanostructured MOx depend on their composition
