Abstract Background: Silica nanoparticles (SiNPs), commonly utilized in industrial and biomedical fields, are known to provoke pulmonary inflammation by elevating cyclooxygenase-2 (COX-2) levels in human pulmonary alveolar epithelial cells (HPAEpiCs). Salvianolic acid A (SAA), a water-soluble polyphenol extracted from Salvia miltiorrhiza (Danshen), possesses well-documented antioxidant and anti-inflammatory activities. Nevertheless, its potential to counteract SiNP-induced inflammatory responses in the lung has not been thoroughly explored. Objective: This study aimed to evaluate the protective role and mechanistic actions of SAA against SiNP-triggered inflammation in both cellular and animal models. Methods: HPAEpiCs were pre-incubated with SAA prior to SiNP exposure to… More >

Abstract The main objective of the study was to prepare a highly active antimicrobial remedy by combining active agents such as tannic acid and silver nanoparticles, which are usually used separately. This was achieved by applying a coating of 11 alternating layers of an insoluble complex of tannic acid with polyvinyl alcohol on paper by the layer-by-layer approach, on the surface of which uniformly distributed spherical silver nanoparticles of uniform size, mainly 20–30 nm, were synthesized by in situ reduction using tannic acid, which also acts as a stabilizer, or an external reducing agent, which prevented polyphenol More > Graphic Abstract

Abstract The food industry prioritizes food safety throughout the entire production process. This involves closely monitoring and evaluating all potential sources of biological or chemical contamination, starting from entering raw materials into the production chain and continuing to the final product. Biofilms on food surfaces or containers can harbor dangerous pathogens, such as Listeria monocytogenes. Therefore, it is essential to continuously manage microbial contamination on food contact surfaces to prevent foodborne infections. Recently, there has been increasing interest in using nanomaterials as surface coatings with antimicrobial properties in the food industry, especially since traditional disinfectants or antibiotics… More >

Abstract Climate change, rising fuel prices, and fuel security are some challenges that have emerged and have grown worldwide. Therefore, to overcome these obstacles, highly efficient thermodynamic devices and heat recovery systems must be introduced. According to reports, much industrial waste heat is lost as flue gas from boilers, heating plants, etc. The primary objective of this study is to investigate and compare unary (Al₂O₃) thermodynamically, binary with three different combinations of nanoparticles namely (Al₂O₃ + TiO₂, TiO₂ + ZnO, Al₂O₃ + ZnO) and ternary (Al₂O₃ + TiO₂ + ZnO) as a heat transfer fluid. Initially, three different types of… More > Graphic Abstract

Abstract The continuous increase in petroleum-based plastic food packaging has led to numerous environmental concerns. One effort to reduce the use of plastic packaging in food is through preservation using biopolymer-based packaging. Among the many types of biopolymers, chitosan is widely used and researched due to its non-toxic, antimicrobial, and antifungal properties. Chitosan is widely available since it is a compound extracted from seafood waste, especially shrimps and crabs. The biodegradability and biocompatibility of chitosan also showed good potential for various applications. These characteristics and properties make chitosan an attractive biopolymer to be implemented as food… More > Graphic Abstract

Abstract The productivity of fruit crops is badly affected by abrupt changes in climatic conditions. It is a matter of concern for fruit tree researchers to feed the huge population within the available resources. The adverse effects of abiotic stresses are increasing due to fluctuations in climate change. Several abiotic stresses (salinity, drought, water logging, minerals deficiency, temperature extremities and heavy metals) are reducing the overall productivity of crops. Therefore, the application of different management approaches, i.e., phytohormones, nanoparticles, organic amendments, microbes and molecular aspects are effective for the mitigation of abiotic stresses in fruit crops.… More >

Abstract Ferroptosis is an iron-driven, phospholipid hydroperoxide-mediated cell death, which has recently emerged as an attractive tool in cancer research due to its ability to govern the anti-tumor immune response. A growing research interest in ferroptosis biology has revealed the contribution of this regulated cell death to multiple diseases. In addition to iron, ferroptosis has been reported to be triggered by multiple heavy metals, which sheds light on the novel aspects of heavy metals-induced cytotoxicity. In this review, the ability of zinc, an essential biogenic element with a wide array of biological functions, to modulate ferroptosis… More >

Abstract In this research, the antibacterial properties of a composite material prepared from agave bagasse cellulose fibers doped with silver nanoparticles and chitosan were studied. The development of composite materials with antibacterial properties and environmentally friendly based on cellulose fibers from agave bagasse with silver nanoparticles prepared by green synthesis and chitosan from shrimp waste enhances the value of these agro-industrial wastes and offers the opportunity for them to have biomedical applications since these raw materials have been poorly reported for this application. The antibacterial properties of chitosan and silver nanoparticles are already known. However, the… More > Graphic Abstract

Abstract The current work includes a numerical investigation of the effect of biodiesel blends with different aluminum oxide nanoparticle concentrations on the combustion process in the cylinder of a diesel engine. IC Engine Fluent, a specialist computational tool in the ANSYS software, was used to simulate internal combustion engine dynamics and combustion processes. Numerical analysis was carried out using biodiesel blends with three Al₂O₃ nanoparticles in 50, 100, and 150 ppm concentrations. The tested samples are called D100, B20, B20A50, B20A100, and B20A150 accordingly. The modeling runs were carried out at various engine loads of 0, 100,… More >

Abstract The impregnation of nanoparticles magnetified into wood had been developed by different methods, like surface chemical coprecipitation and vacuum-pressure coprecipitation of magnetic nanoparticles (NPs). However, there is a lack of information on the best method to coprecipitation NPs. Then, the present study has the objective to measure the effects of the impregnation process of wood veneers through two in situ processes (immersion and vacuum-pressure) using a solution of FeCl₃·6H₂O, FeCl₂·4H₂O and ammonia in three tropical species (Pinus oocarpa, Vochysia ferruginea and Vochysia guatemalensis). It was measured the degree of synthesis of iron NPs using weight and density gains, Fe⁺³ absorption, emission… More > Graphic Abstract
