Indian J Chem Technol 2019, 26(3), 189-204.
Zirconia nanoparticles doped MnCO3 have been successfully immobilized on various percentages of highly reduced graphene oxide (HRG)[(X%)HRG/MnCO3–(1%)ZrOx](where, X=0–7)],via a facile and straight forward co-precipitation method. Upon calcination, the as-obtained materials have yielded different types of HRG/manganese oxide nanocomposites at different temperatures i.e.[(X%)HRG/MnO2–(1%)ZrOx] and [(X%)HRG/Mn2O3–(1%)ZrOx]. A detail investigation was carried out to compare the catalytic performance of carbonates and oxides based nanocomposites for the selective oxidation of secondary alcohols. For this purpose, molecular oxygen was employed as an environmentally benign oxidant under base-free conditions. The reaction conditions were optimized with different weight percentages of HRG, reaction times, calcination temperatures, catalyst dosages, and reaction temperatures using 1-phenylethanol as a substrate model. The catalytic performance of the nanocomposites was enhanced significantly due to the presence of HRG as a support material. The catalyst with (1%)HRG/MnCO3–(1%)ZrOx exhibited outstanding performance as well as excellent selectivity in the aerobic oxidation of 1-phenylethanol. In this case, 100% conversion in 4 min with more than 99% selectivity was achieved with excellent specific activity of 60.0 mmol.g−1.h−1. Moreover, catalyst can be efficiently reused 5 times without discernible decrease in its activity and selectivity. Apart from this, various other alcohols were also selectively oxidized to their corresponding carbonyls with complete conversion in short reaction times under optimal conditions without over-oxidation to the carboxylic acids.

The adsorption of dye C.I. Reactive Red 15 in aqueous solution onto montmorillonite was carried out in detail. The operation parameters influencing the adsorption process of dye C.I. Reactive Red 15 such as contact time and initial dye concentration were studied. Physicochemical characterizations including microscopy and Fourier transform infrared spectroscopy analyses of the surface of montmorillonite were carried out. The kinetic study was performed by the pseudo first order and the pseudo second order reactions. According to the experimental data, the pseudo second order model better described the adsorption of dye onto montmorillonite. It implies that the predominant process is chemisorption, which involves a sharing of electrons between the adsorbate and the surface of the adsorbent. The adsorption isotherms were studied by Langmuir model and Freundlich model. The results indicated that the adsorption followed the Langmuir model. The dye C.I. Reactive Red 15 adsorption onto montmorillonite was monolayer adsorption.

Lanthanum is one of the rare earth elements, which exhibits potential high adsorption capacity for a series of organic and inorganic pollutants. In this research, a lanthanum modified magnetic adsorbent La-modified Fe3O4 was prepared by chemical co-precipitation and used for adsorptive removal of tetracycline (TC) from aqueous solution. At the adsorbent dosage of 5 mg in 50 mL solution, the uptake of TC achieved as much as 83.29 mg/g. The equilibrium adsorption data were fitted by Langmuir, Freundlich, Temkin, RedlichPeterson and Koble-Corrigan models. The R2 values of Freundlich, Redlich-Peterson and Koble-Corrigan models were higher than those of Langmuir and Temkin models. This indicates the chemisorption occurring on heterogeneous adsorbent surface. At 298, 308 and 318 K, the qmax values by Langmuir model were of 110.4, 145.9 and 176.0 mg/g, respectively. Thermodynamic analysis indicates that ΔH° and ΔS° were 29.83 KJ/mol and 124 J·mol-1·K-1, respectively. This demonstrates that the adsorption process was spontaneous and endothermic in nature.

J Pharm Bioall Sci 2019, 11(2), 105-15.
A recent approach in shampoo research has been to find a natural alternative for synthetic detergents that have deteriorative effects on hair follicles. This study aimed at the formulation of a completely herbal shampoo containing a natural foaming agent, in addition to having conditioning, antioxidant, and antimicrobial effects. The leaves of Salix babylonica L., Ziziphus spina-christi L. (Willd), and Glycyrrhiza glabra rhizomes were extracted with 70% methanol then quantified for their phenolic and flavonoid contents using colorimetric assays that were qualitatively identified by Ultra-performance liquid chromatography (UPLC) with tandem mass spectrometry (MS-MS). The mineral content was also estimated. The radical scavenging activity was estimated using 1,1-diphenyl-2-Picrylhydrazyl (DPPH) and the half maximal inhibitory concentration (IC50) was determined. Additionally, the antimicrobial activity was tested using agar diffusion assay and compared to vancomycin and ketoconazole. Four formulations, consisting of the different plant extracts and a combination of the extracts, were prepared and evaluated for several physicochemical properties. The best formula was evaluated for its conditioning effects using scanning electron microscope and blind touch tests by asking volunteers for grading the formulations. UPLC-MS-MS analysis of S. babylonica and Z. spina-christi allowed tentative identification of 12 phytoconstituents in each. Z. spina-christi showed the highest phenolic content and a high copper, zinc, and manganese content beside the best antioxidant activity, whereas G. glabra had a high potency against Bacillus cereus and Candida albicans. The polyherbal shampoo formulation (F4) was selected as an optimized formulation because of a high foam stability after 4 min, low wetting time (2 s), surface tension reduction, and comparable results for percent solid content. F4 showed good conditioning effect and consumer contentment. The formulated polyherbal shampoo is chemical free, extra-nourishing shampoo with excellent conditioning, cleansing, and antimicrobial effects.

J Adv Sci Res 2019, 10(4), 53-9.
The thiocarbohydrazone Schiff base ligand (LH2 ) was synthesized by the condensation of thiocarbohydrazide and 1-(5- bromo-2-hydroxyphenyl)ethanone. Such Schiff base ligand with heteroatoms such as nitrogen, oxygen and sulphur as donor atoms have unique tendency to conjugate with metal ion for the formation of metal complexes. By knowing this fact, a series of Cu(II), Co(II), Th(IV), and Zr(IV) metal complexes were synthesized from (H2L) Schiff base ligand and characterized by using spectroscopic techniques. IR spectra reveal that co-ordination of the ligand with metal ion resulting into mononuclear complexes. The ligand mainly coordinates through the hydroxyl oxygen and azomethine nitrogen to give five membered rings in some cases. Molar conductance values of synthesized metal complexes in DMF indicate the nonelectrolytic nature of the complexes. From the observed magnetic moment and electronic spectral data, probable structures for the complexes have been proposed. The thermal behavior of ligand and metal complexes shows the presence of lattice and the co-ordinate water around their co-ordination sphere. The synthesized Schiff base ligand and its complexes were also tested for their antimicrobial activity against E. Coli, S. aureus, S. epidermis, and K. pneumoniae.

Alphonso) by physiological, biochemical, bio-enzymatic and elemental composition analysis (EDX). Indian J Biochem Biophys 2019, 56(3), 205-13.
The aim of the study was to determine the postharvest fruit quality of mango cv. Alphonso treated with the laboratory grade (LG) and commercial grade (CG) Calcium Carbide (CaC2 ) at the reported highest acceptable dose, and elemental composition analysis (EDX) results to support the statements for traceability of hazardous trace elements in CaC2 , which can serve as a basis towards developing sensors for identifying CaC2 treated mangoes through detection of trace elements. Physical, physiological, biochemical and EDX of mango cv. Alphonso harvested from farmers‘ field of Santur village in Krishnagiri district of Tamil Nadu, India were used for the study. All studied physical characteristics except fruit firmness of CG CaC2 treated fruits did not correlate to desirable fruit characteristics like total soluble solids (TSS), pH, titrable acidity, total sugars and ascorbic acid. Besides, these parameters were desirable only in control fruits, though a number of days taken to reach fruit consumption stage was relatively more compared to CaC2 treatment. In vitro, free radical scavenging potential of DPPH was comparatively higher in control fruits than CaC2 treated fruits of both grades. Lab grade (LG) CaC2 treated fruits were non-significant in modifying physical, physiological and biochemical properties of mango cv. Alphonso except for TSS. However, at the end of the experimental period, CG CaC2 treated fruits recorded higher TSS than LG CaC2 treated fruits. Energy Dispersive X-Ray (EDX) results confirmed traceability of health hazardous chemical substances of arsenic (As) and phosphorous (P) in both LG and CG CaC2 lumps. Calcium carbide when used as an artificial ripening agent was not in contact with the fruit surface, the presence of arsenic and phosphorus were not detected in the EDX spectrum, a novel finding of our study.

Nagar, Uttarakhand) : Methyl nonyl ketone and linalool rich essential oils from three accessions of Zanthoxylum armatum (DC.) and their biological activities. Int J Herb Med 2019, 7(3), 20-8.
Methyl nonyl ketone also known as 2-undecanone (6.7 - 61.2 %) and linalool (1.8 – 48.3 %) were identified as major constituents, analyzed in the essential oils of Zanthoxylum armatum DC. an important medicinal plant from three different ecological niches of Uttarakhand Himalayas in India. The other major constituents in the essential oils were sylvestrene, monomethyl cinnamate, 2- tridecanone, Ecaryophyllene, vinyl decanoate, phytol, caryophyllene oxide, etc. The essential oils exhibited significant antioxidant activity with IC50 values ranging from 13.68 ± 0.35 to 29.67 ± 0.95 µL. The in-vitro antiinflammatory activity with observed IB50 values ranging from 21.56 ± 0.08 to 27.64 ± 0.03 µL has also been found in the essentials, besides moderate anti-bacterial activity. The observed biological potential and diversified chemical makeup of essential oils besides the commercially and biologically important major compounds, it can be inferred that this medicinally important indigenous shrub may be a good source of important phytochemicals like methyl nonyl ketone, cosmetically important linalool for the development of herbal nutraceuticals and cosmeceuticals.

CdS–CuS heterojunction films have been grown successfully on a copper substrate using a chemical bath deposition (CBD) method. The obtained films are characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), optical absorption, Raman spectroscopy and photoluminescence (PL) analysis and the photo-electrochemical (PEC) properties of the CdS–CuS heterojunction have been studied using different electrolytes. The XRD pattern of CuS–CdS shows peaks corresponding to CuS (hexagonal) and CdS (cubic) structures, while the optical absorption studies revealed the presence of an absorption edge corresponding to CuS–CdS (band gap of 1.85 eV). The Raman spectra of the CuS, CdS and CuS–CdS heterojunctions were recorded and are in good agreement with the results reported in the literature. TEM and cross-sectional SEM images show an overlap between CuS rods and CdS flasks. The charge transfer across the layers was studied by using PL spectra. The measurement of the photo-electrochemical properties using a conventional two electrode system for an iodine electrolyte showed the highest conversion efficiency of 1.40% as against for potassium ferro–ferricyanide (0.38%) and polysulphide electrolytes (0.02%).

In the present study, superoxide dismutase (SOD) mimic activity of ferrite nanoparticles (NPs), having a formula MFe2O4 (M = Mn, Co and Cu) was investigated. Spinel ferrite NPs were synthesized by employing sol–gel methodology and characterized using scanning electron microscopy, X-ray diffraction, BET analysis and Fourier transform infrared spectroscopy techniques. BET analysis revealed that the surface area of ferrite NPs ranged from 0.43−23.49 m2g−1. Enzyme mimic activity was compared using SOD as a model enzyme. CuFe2O4 NPs exhibited a maximum activity followed by CoFe2O4 and MnFe2O4 NPs. The results were correlated with a facile interconversion of the oxidation state leading to a stable electronic configuration in CuFe2O4 NPs. Optimum pH and contact time was 1 and 3 min respectively. Kinetic studies were performed under optimum conditions and data were analysed using the Michaelis Menten equation. The values of Vmax (0.77 s−1) and Km (4.20 mM) proved CuFe2O4 NPs as potential SOD mimic for a wide range of applications.

Bull Mater Sci 2019, 42(3), 116.
In this work, the preparation of an antibacterial galactomannan/Zn(OH)2–ZnO composite material by a green process is proposed and demonstrated. The galactomannan polysaccharide was extracted from the arid-native mesquite (Prosopis spp.) seeds through a hydrothermal technique, and it was used as an organic polymeric matrix for the in situ chemical precipitation of the Zn(OH)2–ZnO inorganic particles from simple reactions between Zn2+ and NaOH. The preparation was performed under standard conditions in aqueous solutions. The composite material, which was obtained by centrifugation of the previous preparation, was characterized by X-ray diffraction, transmission and scanning electron microscopy, infrared spectroscopy and thermal analysis. By means of these techniques, it was deduced that the composite material is highly crystalline (about 94 %), composed of about 92 % inorganic and 8 % organic portion, and has a predominant size of 760 nm and a mean size of 800 nm. The antibacterial activity of the composite material was also studied, which resulted better against Escherichia coli (Gram-negative bacterium) than against Staphylococcus aureus (Gram-positive bacterium), which was calculated in a difference of about 30 %. This work presents the high potential of galactomannans to form functional composite materials with inorganic particles.

Bull Mater Sci 2019, 42(3), 110.
A hydrostatic extrusion (HE) process was applied to commercial pure polycrystalline aluminium (99.9 %) and two aluminium single crystals 111 and 110. On comparison, the results obtained from single crystals and polycrystalline aggregates are unique. Microstructure and crystallographic texture investigations were performed by transmission electron microscopy, electron backscatter diffraction and X-ray diffraction (XRD). Significant differences in grain refinement and texture formation were noticed depending on the starting orientation. The deformed single crystal with 110 starting orientation features an average grain size value of 150 % higher than the second investigated single crystal (0.5 μm for the 111 single crystal and 1.3 μm for the second crystal). In turn, the average grain size obtained for polycrystalline aluminium is 0.9 μm. The deformation process causes a difference in the grain sizes, while a fraction of the high angle grain boundaries have a comparable volume percentage in all the deformed microstructures—reached about 35 %. The qualitative and quantitative XRD texture results proved that the HE process leads to the formation of a characteristic fibrous texture.

Bull Mater Sci 2019, 42(3), 107.
The present work deals with a comparative study of ceramic/ceramic composites for the development of scaffolds for biomedical applications. Wollastonite and forsterite were synthesized by a sol–gel combustion method. The influence of constituents and composition on apatite deposition was studied by fabricating wollastonite/forsterite composites. The X-ray diffraction pattern explains the bone like-apatite deposition within early stages of immersion. The atomic force microscopy micrographs revealed that with an increase in wollastonite content in the composites the roughness was enhanced. Dissolution studies further confirmed the rapid consumption of Ca and P ions from the simulated body fluid. Hence, apatite formation was observed to be more on the surface of a composite containing a higher amount of wollastonite. The results suggest that composites have more influence on the biomineralization activity when compared with pure bioceramics.

A new series of poly(azomethine-ester)s (PAZ-E)s with different (turning ortho, meta and para) positions were synthesized by condensation polymerization. The chemical structure of polymers was verified by 1H-NMR, 13C-NMR, FTIR and UV–Vis measurements. Electrochemical characteristics of the corresponding polymers were obtained with cyclic voltammetric (CV) analysis. Thermal characteristics of the obtained polymers were analysed by TG-DTA, DMA and DSC measurements. The first degradation temperature values of PAZ-E compounds were found between 198 and 250◦C from TGA measurements. Photophysical characteristics of the obtained polymers were explained with photoluminescence (PL) spectroscopy. Molecular weight distributions of (PAZ-E)s were obtained by gel permeation chromatographic (GPC) analysis. Two- and three-dimensional (2D and 3D) properties and images of the synthesized (PAZ-E)s were analysed by SEM and AFM surface analysis techniques, respectively. Electrochemical band gap (Eg') values of (PAZ-E)s P-9, P-10, P-11, P-12, P-13 and P-14 were calculated as 2.58, 2.14, 1.90, 2.06, 1.89 and 1.69 eV, respectively. The Eg' values of the (PAZ-E)s were found to be quite low.

Bull Mater Sci 2019, 42(3), 105.
Synthesis of calcium-substituted sodium borophosphate glasses with compositions xCaO − (30 − x)Na2O − 35B2O3 −35P2O5 (x = 0, 2, 5, 7 and 10 mol%, abbreviated as CNVx) containing additional 1.0 mol% of V2O5 following a melt-quench method has been carried out. Different analytical techniques viz. wide angle X-ray diffraction (to confirm noncrystalline nature), ultraviolet–visible spectroscopy (for optical band gap analysis), infrared absorption spectroscopy (for structural analysis) and differential thermal analysis (to evaluate characteristic temperatures) were employed to characterize the synthesized compositions. The optical band gap is calculated for both indirect allowed and indirect forbidden transitions. The values of the band gap decrease with increasing concentration of CaO (from 5 to 10 mol%) at the cost of Na2O. The cut-off wavelength and Urbach’s energy are determined from the optical absorption spectra and were related to the structural changes occurring in these glasses with an increase in CaO content. The results obtained from Fourier-transform infrared studies confirm that V2O5 and CaO play the role of network modifier oxides. Also, the significant shifting in IR bands with an increase in CaO content in the glass matrix suggests the formation of a new boron–oxygen ring. From differential scanning calorimetry measurements it is observed that substitution leads to the increase in natural bond orbitals, high degree cross-linking and thus strengthens the glass network. Glass transition temperature (Tg) is found to increase from 483 to 522◦C. Electrical and dielectric properties are analysed using dc conductivity and impedance spectroscopy. Using impedance spectroscopy, different dielectric parameters i.e. dielectric loss (ε'), electrical modulus (M∗) and ac conductivity (σac) etc. are evaluated as a function of frequency, temperature and composition. The frequency dependence of impedance exhibits the non-Debye relaxation behaviour and the total conductivity obeys Jonscher’s power law.

Bull Mater Sci 2019, 42(3), 104.
In the present day scenario, the crisis of safe drinking water is an extremely serious issue across many parts of the globe and needs efficient methods to overcome this problem. The effort made in this study is to develop a method to prepare a ceramic membrane with locally available cheap compositions such as potters’ clay, stone dust and tea waste materials for efficient adsorptive dye removal from water. The preparation of ceramic membrane was carried out by a paste pressing method and sintered at an optimized temperature of 900◦C to obtain flat ceramic membranes of 42 mm in diameter and 3 ± 0.5 mm thickness with good thermal and chemical stabilities with 52.51% porosity and average pore size of 0.49 μm. The membrane was capable of decolouring methylene blue and congo red from water with good efficiency and the used membrane was regenerated by calcining at 400◦C for 30 min without much loss of its efficiency. Development of newer advanced products with the available local resources may be another way to sustain the small scale industry and livelihood of the people around.
