Carbon dioxide (CO2) play a basic role as a sustainable feedstock during chemical synthesis. The considered approach should be moderated to be viable. Iron(II) trisbipyridine complex [Fe(Bpy)3]2+ supported over fibrous phosphosilicate (FPS) utilizing dipyridin ligands has been determined as highly valuable catalysts of cycloaddition of ortho-heteroaryl anilines with CO2 during the synthesis of quinoline-2-ones

Water resources may badly have affected by industrial effluents contain organic azo dyes. The present study successfully synthesized silver (Ag) and zinc oxide (ZnO) supported periodic mesoporous organosilicates (Ag-PMOS and ZnO-PMOS) for catalytic degradation of methylene blue (MB) and methyl orange (MO). Initially, methyacryl functionalized periodic mesoporous organosilica (PMOS) framed through tween-80

Manganese ferrites (MnFe2O4) and three different weight percentage of nickel doped manganese ferrites (Ni: MnFe2O4) was prepared through a chemical co-precipitation method. The crystal structure, crystallite size, and phase of the prepared materials are determined by X-Ray Diffraction technique (XRD). The average crystallite size was calculated to be 44 nm, 42 nm, 37 nm, and 35 nm for MnFe2O4, Ni1%Mn(x-1%)

Fly ash-based geopolymer incorporated with 2% nano-SiO2 (NS)/nano-TiO2 (NT) particles was subjected to microstructural and statistical nanoindentation analysis. With the addition of both types of nanoparticles, the compressive strength of geopolymer and the micromechanical properties of N-A-S-H gel were increased. NS exhibited higher reinforcement effect than NT on macro-strength. However, NT more

In this work, barium sulfate (BS) fibers with a three‐level nanorod‐assembled hierarchical structure have been synthesized in a large scale by the barium oleate precursor hydrothermal method. A new kind of anti‐acid and anti‐alkali fire‐resistant BS inorganic paper has been developed using BS fibers, glass fibers and inorganic adhesive, and has the advantages such as high flexibility, good tensile

Chirality is one of the most important topics in chemistry attributable to the peculiar stereochemical properties. Since the chirality belongs to one of the noncentrosymmetric (NCS) crystal classes, chiral materials may reveal second‐harmonic generation (SHG) properties, one of the unique structure‐related properties. The high efficiency of SHG can be achieved by the well‐controlled alignment of NCS

Potentially tridentate, phosphine‐containing Schiff bases with P,N,O and P,N,P donor sets have been prepared from 2‐(diphenylphosphino)benzaldehyde, salicylaldehyde, 2‐aminophenol and 2‐((diphenylphosphino)phenyl)­methylamine and reacted with (NEt 4 ) 2 [Re(CO) 3 Br 3 ] in methanol. Deprotonation and the formation of neutral [Re(CO) 3 (L)] complexes with tridentate coordination of the Schiff bases

ZnSe nanocrystals (NCs) were synthesized by aqueous method and were grown by microwave irradiation times (MWIRT) of 0-6 min at fixed solution pH of 11.2. Disk diffusion antibacterial property of these nanocrystals owing the mean size of ∼2 nm, was carried out against the gram negative bacteria of Escherichia coli and Pseudomonas aeruginosa, by considering nanoparticle loading volumes of 140 and 70

In this work, to enhance supercapacitor research performance, we have prepared two different types of ferrites as CoFe2O4 and NiFe2O4 nanoparticles by two different routes, such as co-precipitation followed by hydrothermal method and facile hydrothermal method for the first time. In order to study the structural, morphological, and elemental composition of the fabricated ferrite electrodes, various

Multi-walled carbon nanotubes (MWCNTs) were introduced into titanium dioxide (TiO2) photoanode films in quantum dot sensitized solar cells (QDSCs) to modify the microcracks structure that produced during the sintering process. The effect of different mass fractions (0%, 0.01%, 0.05%, 0.1% and 0.3%) of MWCNTs and photoanode film thickness on the performance of QDSCs was investigated. BET test verified

Sucrose mediated LaAlO3: Ce3+ nanopowders were prepared by propellant chemistry technique. The preliminary characterizations were carried out using Powder X-Ray Diffraction (PXRD), Fourier Transform InfraRed spectra (FTIR), Scanning Electron Microscopy (SEM) and transmission electron microscopy (TEM) to analyse the structure and morphology of the prepared nanophosphors. PXRD studies showed pure rhombohedral

Two hybrid materials (1_TiO2 and 2_TiO2) were designed and prepared by anchoring novel [Cp*Ir(κ3‐O,N,O‐glyphosate)] (1; glyphosate = N‐(phosphonomethyl)glycine) and [Cp*Ir(κ3‐O,N,O‐glyphosine)] (2; glyphosine = N,N‐bis(phosphonomethyl)glycine) complexes onto rutile TiO2. Characterization in solution (NMR spectroscopy) and solid state (X‐Ray diffractometry) indicates that 1 and 2 are stabilized by the

On August 8, 2019, an explosion of a military missile occurred at the Nenoksa (also transcribed as Nyonoksa) Missile Test Center (Russian Federation). Russian authorities confirmed a release of radioactive material in the course of this incident, which fueled rumors that it could have involved a nuclear‐propelled missile of the Burevestnik/Skyfall type. In this study, our radioanalytical efforts are

Abstract In the current research, two new Cu(II)-containing coordination polymers with the chemical formulae of [Cu2(L)2]·2DMA·3H2O (1) and [Cu2(L)2]·H2O (2, H2L = 2-(imidazol-1-yl)terephthalic acid) have been solvothermally synthesized by reaction of Cu(NO3)2·3H2O with the H2L ligand in different solvent systems (DMA/H2O for 1 and NMP/H2O for 2), which have been well characterized by elemental analysis

ABSTRACT In the preservation of cultural heritage, the measurement of pH has implications both as a parameter for assessing the state of conservation and as a reference for the preparation and use of aqueous treatment solutions. Few studies in the relevant literature, however, deal with evaluating the reliability of measurements. The purpose of this study was to identify the best method and the confidence
