Surface functionalizedCasuarina equisetifoliapine powder for the removal of hetero-polyaromatic dye: characteristics and adsorption

The seed ofCasuarina equisetifolia, the genus of Pinus of the familyPinaceaewas examined for the potentiality of adsorbing a thiazine-based hetero-polyaromatic dye from water system. For which, the surface functionalization ofCasuarina equisetifolia(SFCE) was achieved through H(2)SO(4)acidic bath to treat methylene blue (MB) dye contaminated water. The SFCE was characterised using scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) to analyse morphological, physical and chemical behaviour after surface modification. The effects of adsorption process influencing variables such as pH, concentration of MB dye, contact time and temperature was examined. The maximum adsorption capacity of 0.5 gL(-1)SFCE for the concentration ranging from 20 to 100 mgL(-1)of MB was investigated using different variables. The effect of parameters including pH, time and temperature were optimised at a speed of agitation of 150 rpm. The adsorption data retrieved from batch experiments were fit with Langmuir, Freundlich, Temkin and Dubinin-Raduskevich (D-R) isotherm models, and as a result, Freundlich presents the best fit (R-2 > 0.97). Pseudo-second order kinetic was superior indicating that SFCE-MB system has undergone the chemisorption mechanism (R-2 > 0.99) spontaneously. Overall, the tested system with synergistic effect was witnessed with maximum adsorption efficiency of 42.19 mg g(-1)to remove dye from industrial wastewater.

Sublimation enthalpy of 1,3-thiazine structural analogues: Experimental determination and estimation based on structural clusterization

The saturated vapor pressures of 4 nonaromatic bicyclic 1,3-thiazine and 1,3-selenazine derivatives have been measured by the method of transpiration by inert gas-carrier in the temperature range of 308-392 K. Based on the experimental data the thermodynamic functions of sublimation have been calculated. The sublimation enthalpies of the compounds vary from 104 to 150 kJ mol(-1) depending on the chemical nature of the substituent in the aryl moiety and the heteroatom in the bicyclic fragment. The crystal lattice energy of thiazines decreases with the introduction of substituents in the following order: cyano > acetyl > isopropyl. New approach has been suggested to evaluating sublimation enthalpy of the studied and structurally related compounds by using clusterization of the space of experimental points.

A Facile and Chemoselective Synthesis of Novel Pyrimido[5,4-b][1,4]thiazines by exo-dig Iodocyclization Reactions

The present manuscript involves the synthesis of 5-prop-2-ynylsulfanyl-pyrimidin-4-ones 3a-i by [4+2] cycloaddition reactions of 1,3-diazabuta-1,3-dienes 1a-i with prop-2-ynyl-sulfanyl ketene 2. These 5-prop-2-ynylsulfanyl-pyrimidin-4-ones 3a-i were explored in iodocyclization for the synthesis of novel pyrimido[5,4-b][1,4]thiazines 4a-i in excellent yields. The iodocyclizations followed exo-dig ring-closure cyclizations to yield 6-6 bicyclic fused pyrimidinones, while corresponding endo-dig ring-closure iodoamination was not observed.

Characterization of biogenically synthesized silver nanoparticles for therapeutic applications and enzyme nanocomplex generation

The present study describes green synthesis of silver nanoparticles (AgNPs) and inulin hydrolyzing enzyme nanocomplexes (ENC) usingAzadirachta indica(Ai) andPunica granatum(Pg) leaf extracts. Surface topology and physico-chemical characteristics of AgNPs were studied using surface plasmon resonance (SPR), FTIR, SEM, AFM and EDX analyses. Particle size analysis using dynamic light scattering and AFM studies revealed thatAi-AgNPs (76.4 nm) were spherical in shape having central bigger nano-regime with smaller surroundings whilePg-AgNPs (72.1 nm) and ENCs (Inulinase-Pg-AgNPs similar to 145 nm) were spherical particles having smooth surfaces.Pg-AgNPs exhibited significant photocatalysis of a thiazine dye, methylene blue. BothAi-andPg-AgNPs showed selective antibacterial action by inhibiting pathogenicBacillus cereus, while the probioticLactobacillusstrains remained unaffected.Ai-AgNPs showed potential anti-biofilm effect (30% viability) onB. cereusbiofilms.Pg-AgNPs showed anti-cancer effect against human colon cancer cell lines (Caco-2) resulting in 40% cell death in 48 h. Enzymes (inulinase, L-asparaginase and glucose oxidase) were successfully immobilized onto nanoparticles together with the biogenic synthesis of AgNPs and recyclability of the Inulinase-Pg-AgNPs complex was demonstrated. The study elaborates characteristics of green synthesized nanoparticles and their potential applications as anti-cancer, antibacterial and antioxidant nano drugs that could be used in food and nutraceutical industries. Enzyme immobilization on AgNPs without any toxic cross-linker opens up newer possibilites in enzyme-nanocomplex research.

Ecofriendly pH-Tunable Hydrogels for Removal of Perilous Thiazine Dye

Reactive dyes are extremely toxic and harmful to the environment even present at very low concentration. In this study, sodium alginate based reusable hydrogels was prepared for the removal of methylene blue from waste water. pH-tunable hydrogels was prepared by the introduction of ionic pendant functionalities on sodium alginate (SA) by the utilization of ethylene glycol and acrylic acid through condensation followed by free radical polymerization. The structure, formation and thermal stability of hydrogel was identified by Fourier transform infra red spectroscopy and thermogravimetric analysis respectively. Swelling nature at different pH ranges and the humidity contents of both dried and dye adsorbed hydrogels was investigated. The morphology of the dry and dye adsorbed hydrogel was also studied using scanning electron microscopy. The swelling studies infer that pronounced swelling obtained at higher pH than at lower pH. The surface morphology of plain hydrogel before and after adsorption of methylene blue (MB) was examined by SEA analysis. The adsorption tendency of the SEA hydrogel in MB was steadily investigated at different pH, contact time, concentration dye and adsorbent dosage. All prepared hydrogels were performed well in the removal of MB from waste water up to 80-98%. Recycling of hydrogels has a vital role for waste water treatment and it can be done by desorption studies which shows that 0.1 N HCl revealed higher elution efficiency i.e. 90.00%. Furthermore, adsorption-desorption studies suggested that SA based hydrogels contributes to enhance the removal efficacy, which renders the hydrogels well-designed for the efficient removal of cationic dyes (MB). However, polyol based hydrogels have been chosen for an adsorbent because of low-cost, ecofriendly, biocompatible and efficient biosorbents. [GRAPHICS] .

Crystal structure, Hirshfeld surface analysis and interaction energy, DFT and antibacterial activity studies of (Z)-4-hexyl-2-(4-methylbenzylidene)-2H-benzo[b][1,4]thiazin-3(4H)-one

The title compound, C22H25NOS, consists of methylbenzylidene and benzothiazine units linked to a hexyl moiety, where the thiazine ring adopts a screw -boat conformation. In the crystal, inversion dimers are formed by weak C Hmthn’ OBnzthz hydrogen bonds and are linked into chains extending along the a -axis direction by weak C H- -Bnz OBnzthz (Bnz = benzene, Bnzthz = benzothiazine and Mthn = methine) hydrogen bonds. A Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H H (59.2%) and H -C/C- H (27.9%) interactions. Hydrogen bonding and van der Waals interactions are the dominant interactions in the crystal packing. Computational chemistry indicates that in the crystal, the C HBnz OBnzthz and C HMthn. OBnzthz hydrogenbond energies are 75.3 and 56.5 kJ mol-1, respectively. Density functional theory (DFT) optimized structures at the B3LYP/ 6-311 G(d,p) level are compared with the experimentally determined molecular structure in the solid state. The HOMO LUMO behaviour was elucidated to determine the energy gap. Moreover, the antibacterial activity of the title compound was evaluated against gram -positive and gram-negative bacteria.
