a novel acrylic acid-functionalized fe3o4 magnetic nanoparticle with a core-shell structure was developed for utilization as a heterogeneous organosuperacid in chemical transformations. the structural, surface, and magnetic characteristics of the nanosized catalyst were investigated by various techniques such as transmission electron microscopy (tem), thermogravimetric analysis (tga), and ft-ir...
Abstract The widespread use of antibiotics has resulted in the emergence multidrug-resistant bacteria. Therefore, it is essential to explore alternative strategies effectively combat medically significant resistant pathogens. In recent years, nanoparticles (NPs) have emerged as a promising source antimicrobial agents. While nanoscale particles were traditionally synthesized using chemical techn...
The abiotic reduction reactions that form the basis of in situ chemical reduction (ISCR) have been studied extensively, but there has been little effort to develop a unified understanding of what factors control ISCR performance. Some of the key factors are summarized here, with the ultimate goal of building a basis for rational design of better ISCR reductants. INTRODUCTION The fact that groun...
background: today the use of natural substances plays a major role in improving the growth and immunity of aquatic organisms. objectives: the purpose of the present study was to evaluate the effects of iron nanoparticles with lactobacillus casei as a probiotic on growth parameters and probiotic counts in rainbow trout intestine. methods: seven hundred and twenty fish with 12±0.49 g initial weig...
background and purpose:organic dyes with a complex structure are often toxic, carcinogenic, mutagenic, non-biodegradation and stable in the environment and if released to the environment without treatment can endanger the environment and human health. the aim was to evaluate the performance nanoscalezero-valent iron (nzvi) in the removal of dye acid red 18 (ar18) from aqueous solutions. materia...
Silver and gold nanoparticles display unique physical and biological properties that have been extensively studied for biological and medical applications. Typically, gold and silver nanoparticles are prepared by chemical reductants that utilize excess toxic reactants, which need to be removed for biological purposes. We utilized a clean method involving a single synthetic step to prepare metal...
