Abstract Topological indices are numerical numbers associated to molecular graphs and are invariant of a graph. In QSAR/QSPR study, Zagreb indices are used to explain the different properties of chemical compounds at the molecular level mathematically. They have been studied extensively due to their ease of calculation and numerous applications in place of the existing chemical methods which needed more time and increased the costs. In this paper, we compute precise values of new versions of Zagreb indices for two classes of dendrimers.

Abstract Recently, sonochemistry has been used for the synthesis of inorganic compounds, such as zinc borates. In this study using zinc sulphate heptahydrate (ZnSO4·7H2O) and boric acid (H3BO3) as starting materials, a zinc borate compound in the form of Zn3B6O12·3.5H2O was synthesized using an ultrasonic probe. Product’s characterization was carried out with using X-ray diffraction (XRD), Scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FT-IR) and Raman spectroscopy. Zinc borate compound’s chemical bond structure was observed with Raman and FTIR. From the XRD results it was seen that Zn3B6O12·3.5H2O can be quickly synthesized upon heating at 80°C and 85°C (55 min) or 90°C (45 min) in very high yield (>90%). The minimum particle size obtained was ~143 μm from the SEM results. Zinc borate compound was synthesized at a lower temperature in less time than other synthesized zinc metal compound in literature.

Abstract A massive of early drug tests indicates that there is some strong inner connections among the bio-medical and pharmacology properties of nanostar dendrimers and their molecular structures. Topological descriptors are presented as fundamentally transforming a molecular graph into a number. There exist various categories of such descriptors particularly those descriptors that based on edge and vertex distances. Topological descriptors are exercised for designing biological, physico-chemical, toxicological, pharmacologic and other characteristics of chemical compounds. In this paper, we study infinite classes of siloxane and POPAM dendrimers and derive their Zagreb eccentricity indices, eccentric-connectivity and total-eccentricity indices.

Abstract The entropy-based procedures from the configuration of chemical graphs and multifaceted networks, several graph properties have been utilized. For computing, the organizational evidence of organic graphs and multifaceted networks, the graph entropies have converted the information-theoretic magnitudes. The graph entropy portion has attracted the research community due to its potential application in chemistry. In this paper, our input is to reconnoiter graph entropies constructed on innovative information function, which is the quantity of different degree vertices along with the quantity of edges between innumerable degree vertices.”In this study, we explore two dissimilar curricula of carbon nanosheets that composed by C4 and C8 denoted by T1C4C8(S)[m, n] and T2C4C8(R)[m, n]. Additionally, we calculate entropies of these configurations by creating a connection of degree-based topological indices with the advantage of evidence occupation.

Abstract β-diketiminate coordinated magnesium(I) compounds, [{(ArNacnac)Mg}2] (ArNacnac = [(ArNCMe)2CH]– (Ar = 2,6-diisopropylphenyl (Dip) or mesityl (Mes)), have been utilized as reducing agents in reactions with the redox active 1,4-diazabutadiene, (ButNCH)2 (ButDAB), and 2,2’-bipyrine (bipy). These reactions led to one-electron reductions of the unsaturated substrate, and formation of the highly colored radical complexes, [(ArNacnac) Mg(ButDAB•)] and [(MesNacnac)Mg(bipy•)(bipy)]. The X-ray crystal structures of the compounds reveal each to possess one singly reduced ButDAB or bipy ligand.

Abstract Lithium (Li) is a widely-used medication for the treatment of patients with bipolar disorder. Li causes different complications. One of the most important adverse effects of Li is neurotoxicity. Neurotoxicity is usually irreversible which may lead to very important complications. The symptoms of Li-induced neurotoxicity include tremor, delirium, seizures, coma, and death. In this study, we wanted to evaluate the exact sub-cellular mechanisms of Li-induced neurotoxicity. For this purpose, we used primary neuronal cortical culture for investigating lithium-induced neurotoxicity. We applied the postnatal rat pups for isolating the cortical neurons. After that, we evaluated neural viability, neural reactive oxygen specious (ROS), lipid peroxidation, mitochondrial membrane potential (MMP), lysosomal membrane integrity (LMI), and reduced (GSH) and oxidized (GSSG) glutathione. Our results demonstrated that the cytotoxic effect of Li has mediated through lysosomal membrane leakage associated with ROS formation and reduction of MMP. Furthermore, the incubation of isolated neurons with Li caused rapid GSH depletion (as GSSG efflux) as another marker of cellular oxidative stress. We concluded that Li causes neurotoxicity in a dose-dependent manner. Besides, Li-induced neurotoxicity is a result of the generation of ROS and LP, which leads to mitochondrial/lysosomal toxic cross-talk.

Abstract A new 2D dibutyltin coordination polymer with 3,5-dinitrosalicylate and 4,4’-bipyridine ligands, [{Bu2Sn(3,5–(NO2)2–2–OC6H2COO)}2(4,4’-bpy)]n (1), has been synthesized and characterized both spectroscopically (IR, 1H, 13C, and 119Sn NMR) and a single-crystal X-ray diffraction analysis. The coordination geometry of tin atom in 1 is a distorted octahedron. 3,5-Dinitrosalicylate as doubly charged anion ligand adopts chelating-bridging mode to coordinate to tin atoms, and 4,4’-bipyridine further bridges the tin atoms to form a 2D herringbone-like network structure containing the 34-membered hexa-nuclear macrocycles.

Abstract Increased growth of textile industries leads to the tremendous accumulation of dyes on water and surrounding environments. This terrific increase of dyes is the major cause of water pollution which in turn adversely affects the aquatic lives and the balance of our ecosystem. Purpose of the present study is to report the synthesis and characterization of a composite namely zinc oxide incorporated nanocellulose (ZnO/NC) for effective degradation of an anionic dye, Congo red. Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), Brunaeur, Emmett and Teller (BET) surface area analysis and scanning electron microscopy (SEM) studies have helped to characterize the composite. The optical properties of the samples were studied by UV-Visible spectroscopy. Feasibility of the photocatalyst in the degradation of Congo red was tested. Experimental conditions such as time of contact, concentration of the dye solution, catalyst dosage, pH were altered to find out the optimum conditions of degradation. The optimum pH was found to be 5.5 and dosage of ZnO/NC was optimized as 0.075 g for a dye concentration of 20 ppm. Equilibrium was attained at 120 min. The studies reveal that the photocatalyst ZnO/NC is efficient for the photodegradation of Congo red. Photodegradation was due to electron hole interaction between metal oxides and nanocellulose.
