The aim of this study was to develop nanoemulsion formulations of tarragon (Artemisia dracunculus) essential oils and to investigate their antioxidant, antimicrobial and anticancer properties. Tarragon is a plant rich in tannins, flavonoids, vitamins and other bioactive compounds, and has attracted attention for its antioxidant, antimicrobial and anticancer potential. Tarragon nanoemulsions...

Today, with the developing technology and industrialization, the wastewater brought by the rapid population growth parallel to industrial progress threatens the environment and ecosystems more and more every day. Synthetic dyes are seen as one of the biggest causes of environmental pollution. Synthetic dyes, especially azo-dyes, are used in many areas, especially in textiles, leather,...

Water is one of the basic elements for living and has an important role in terms of the sustainability of ecosystems and human health. Water, which is involved in the stages of biological, physiological, and chemical processes of living things, is also used in many sectors, such as industry and energy production. The availability of clean and adequate water is important for food security and...

In recent years, synthetic colorants have been used more widely in the food industry instead of natural colorants. Synthetic colorants offer many advantages over natural dyes, such as high stability to light, oxygen and pH fluctuations, uniformity in color, high brightness, minimum sensitivity to microbiological contamination, a wide range of shades and relatively low production costs....

By using nanotechnology, it is possible to achieve properties of materials that are not visible in larger-sized. Bentonite is a mineral from the group of sheet phyllosilicates, which is mainly composed of the mineral montmorillonite. Pure montmorillonite (nano-clay) is the most widely used clay mineral in various industries, especially the medical and pharmaceutical industries. Since...

In recent years, the superior computational power of deep learning based on software has been widely recognized, and the practical applications of artificial intelligence are rapidly expanding. On the other hand, the hardware for replacing to such artificial intelligence (AI) algorithms is facing the physical limits of scaling in silicon CMOS technology, and performance improvement is expected...

Nano-clays are hydrous silicate minerals with a sheet structure that have a special place in various industries, especially in the field of health and treatment, due to their nano-metric dimensions (at least in one dimension) and unique structural properties. The presence of a negative surface charge with strong physical adsorption capacity is one of the valuable structural features of these...

Clay minerals are hydrous silicate sheets with a layered structure of the phyllosilicate type, which are composed of oxygen (O) and hydroxide (OH) layers. Generally, they are product of chemical weathering of other silicate minerals on the Earth's surface, and are considered to be among the most abundant substances in nature. In mineralogy, particles smaller than 4 microns (0.004 mm) are...

The frequency of diseases in certain regions of the world and the use of various minerals to treat diseases throughout history, indicate that there is a direct and close relationship between geological processes and the health of living organisms. The effective relationship between geological indicators and human, animal and plant health, as well as understanding the impact of environmental...

Abstract: The properties of synthesized carbon quantum dots (CQDs) depend on the precursor type and synthesis method. Therefore, selecting an appropriate precursor is the first step in the controlled production of CQDs. The synthesis method should be simple, environmentally friendly, and utilize materials that can replace conventional toxic substances. For this purpose, a green approach is...

In recent years, advances in nano-scale technology have led to the use of nanoparticles in almost all areas of life. Nanoparticles have been acknowledged as one of the emerging environmental threats; however, studies in different components of environment are limited. Among the available nanoparticles, zirconium oxide nanoparticles (ZrO2-NPs) are widely used in tooth coating and cosmetic...

Abstract
Carbon Quantum Dots (CQDs), a new generation of carbon-based nanomaterials, have attracted significant attention in scientific research due to their unique optical properties, high biocompatibility, low toxicity, and excellent chemical stability. Their low production cost and versatility in applications such as bioimaging, biosensors, drug delivery, and energy storage, especially...

Abstract
In this research, a graphene oxide/MnO₂ quantum dot (GO/MnO₂-QDs) nanocomposite was utilized as a solid-phase adsorbent to remove Ni²⁺ and Cr⁶⁺ metal ions from water and wastewater samples. This approach leverages the adsorption capabilities of the nanocomposite to effectively capture and eliminate these heavy metal contaminants, offering a potential solution for purifying water...

Pituitary adenomas constitute the most frequent neuroendocrine pathology, comprising up to 15% of primary intracranial tumors. Current therapies for pituitary tumors include surgery and radiotherapy, as well as pharmacological approaches for some types. Although all of these approaches have shown a significant degree of success, they are not devoid of unwanted side effects, and in most cases...
