Electrochemical properties of ruthenium oxide (RuO₂)/oxidized multi-walled carbon nanotube (MWCNT) (RuO₂/MWCNT) composite electrodes in supercapacitors were investigated. The electrodes were prepared by impregnating MWCNTs with different concentrations of RuCl_3•xH₂O solution, followed by chemical reduction and annealing at 150°C under a nitrogen atmosphere. 

Encapsulation of therapeutic molecules (e.g., small molecule inhibitors, mRNA, siRNA, aptamers, etc.) into nanomaterials can improve the solubility and blood circulation of the drugs, alter their biodistribution, decrease their toxicities, overcome drug resistance, and facilitate their entry into target cells. The development of anti-cancer nanodrugs has been the focus of intense study for decades. Several anti-cancer nanodrugs have been approved for clinical use all over the world.

The manufacture of scaffolds for wound healing has become important, especially the formation of tissuespecific scaffolding. In order to create scaffolds, it is essential to mimic the chemical composition, physical morphology and biological functions of the human body. Scaffolds can be created by using synthetic polymers (e.g. polycaprolactone) or natural polymers (e.g. chitosan) or a combination of both. The addition of natural polymers can be very advantageous as they can avoid

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,

Cancer nanomedicine was originally developed for more efficient delivery of chemotherapeutic agents into tumor, and has been extensively employed as a therapeutic for cancer treatment owing to its unique features in drug delivery, diagnosis and imaging, as well as the therapeutic nature of some nanomaterials themselves.

The study of surface and interfacial science via analytical techniques is a growing interest in the easy mode of diagnosing probe molecules adsorbed on the surface. In that line, Raman spectroscopy is an analytical method that is inefficient to carry the surface analysis employing their weak cross-sectional scattering until the discovery of Surface-Enhanced Raman Scattering (SERS) in late 1970s

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.

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.

Nanotechnology is an evolving revolution with enormous promise in a variety of fields, including mechanics, medicine, and the food business. Nanoparticles owing to having greater surface area and enhanced rates of mass transfer seem to pose higher biological and chemical activities, penetrability, catalytic behaviour, enzymatic reactivity, and quantum

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.

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.

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

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.

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.

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.

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.
