BackgroundThe degree sequence of a graph is the list of its vertex degrees arranged in usually increasing order. Many properties of the graphs realized from a degree sequence can be deduced by means of a recently introduced graph invariant called omega invariant.MethodsWe used the definitions of the considered graph products together with the list of degree sequences of these graph products for some well-know gra Read More

IntroductionThe objective of this study is to compute the Kirchhoff index and resistance distance for two classes of windmill graphs, namely the French windmill graph and the Dutch windmill graph.MethodsIn this study, G is considered a simple connected graph with vertex set V (G) and edge set E (G). N is supposed to represent a network derived from G by substituting a 1-ohm resistor for each edge of G. In that case, the resi Read More

BackgroundIn China, the traditional method for analyzing soil available phosphorus is inadequate for large-scale soil assessment and nationwide soil formulation demands. To address this, we propose a rapid and reliable method for soil-available phosphorus detection. The setup includes an on-site rapid pre-treatment device, a non-contact conductivity detection device, and a capillary electrophoresis buffer solution system com Read More

Oxazolines are important heterocyclic systems due to their biological activities, such as antibacterial, antimalarial, anticancer, antiviral, anti-inflammatory, antifungal, antipyretic, and antileishmanial. They have been widely applied as chiral auxiliaries, polymers, catalysts, protecting groups, building blocks, and ligands in asymmetric synthesis. Due to their importance, many synthetic routes to prepare oxazoline moiet Read More

Cellulose nanocrystals (CNCs) have triggered considerable research interest in the last few years owing to their unique optical, biodegradation, and mechanical behavior. Herein, recent progress on the sensing application of photonic CNC films is summarized and discussed based on the analyses of the latest studies. We briefly introduce the three approaches for preparing CNCs: mechanical treatment, acid hydrolysis, and enzymat Read More

Natural polysaccharide-based nanoparticles are known for their non-toxic nature and diverse medical applications. Graphene oxide (GO) nanoparticles show potential in cancer treatment due to their ability to target medication delivery and influence ROS generation. These nanocomposites are versatile in gene transport, therapy, and photodynamic therapy, especially when surface-modified. Proper dispersi Read More

BackgroundNitroaromatic compounds are important scaffolds used for the synthesis of a variety of compounds, such as explosives, herbicides, dyes, perfumes and pharmaceuticals. Bismuth nitrate pentahydrate is a widely used reagent in organic synthesis; however, its utility as a nitrating agent for anilines is underexplored.ObjectiveThe aim of this work is to propose and find the proper reaction conditions of an alternative Read More

BackgroundOne of the most researched issues is the elimination of uremic toxins from the human body. These toxins can build up and lead to catastrophic issues including renal failure. To get rid of them, absorbents like activated carbon, zeolites, and other minerals are frequently utilized.MethodsMesoporous silica nanoparticles functionalized with (3-Aminopropyl) triethoxysilane (APTES) linker (MSN-NH2) and meso Read More

AimsThe small organic molecular compounds with biological activity containing C-C and C-N or C-O bonding were efficiently prepared without catalyst and solvent in the hydrothermal synthesis reactor.ObjectivesOur goal was to explore new applications for the more environmentally friendly and efficient synthesis of bis(indolyl)methyl, xanthene, quinazolinone, and N-heterocyclic derivatives in hydrothermal synthesis r Read More

IntroductionThe effect of power and duration of ultrasonic irradiation on the synthesis of thiazoles via the Hantzsch reaction was investigated.MethodsThe reaction of phenacyl bromides with thioamides under ultrasonic irradiation afforded the target thiazoles in good yields.ResultsThe results showed that high power and long irradiation time cause the decomposition of the reaction materials, and for th Read More

IntroductionA new series of 4-hydroxy-8-methyl-2-oxo-1,2-dihydroquinoline-3-carboxamide derivatives has been synthesized in good yields, followed by complete characterization using 1D-NMR, 2D-NMR, and IR techniques.MethodsThe final products contain amide, hydroxyl, and aromatic functional groups that usually show significant bioactivity. The target products have been examined towards three cancer cell lines, nam Read More
