Abstract Organic- inorganic hybrid perovskite shows promising properties such as optical, electrical, and magnetic. To address issues in the standard methylammonium lead iodide perovskite such as toxicity and stability, lead was replaced with Cu in metal ion part and iodine replaced by chlorine in the anionic position. In this work, methyl ammonium copper chloride (MA2CuCl4) and phenyl ethyl ammonium copper chloride (PEA2CuCl4) were synthesised. Optical and structural property variations of solution obtained by mixing MA2CuCl4 and PEA2CuCl4 in 1:1 ratio was studied. Methylammonium lead iodide

Streszczenie:

To improve the compatibility and dispersion of the sepiolite in polymers, a surfactant of octadearyl dimethyl ammonium chloride（OTAC）was used to modify sepiolite. The experiment was used to analyze the effects of OTAC dosage, reaction temperature and reaction time on the wettability of organically-modified sepiolite. The effects on the structure performance of sepiolite were investigated by XRD, SEM and contact angle measurements. The orthogonal experimental esults show that the optimum amount of OTAC, reaction temperature and reaction time are 400 mmol/kg, 90 °C and 120 min, respectively.

Herein, a novel chitosan derivative nanoparticle was proposed to function as a delivery carrier. First of all, an improvement was made to the way N-2-hydroxypropyl trimcthyl ammonium chloride chitosan (N-2-HACC) was synthesized. Moreover, the solution to one-step synthesis of N-2-HACC from chitosan (CS) was developed. Different from the previous report, the synthesis process was simplified, and there was a reduction in the amount of 2,3-epoxypropyl trimethyl ammonium chloride (EPTAC) used. With its excellent water solubility maintained, the relatively low degree of substitution was controlled

Abstract. Incubation experiments were conducted using soil samples from a forested riparian wetland where we have previously observed anaerobic ammonium oxidation coupled to iron reduction. Production of both nitrite and ferrous iron was measured repeatedly during incubations when the soil slurry was supplied with either ferrihydrite or goethite and ammonium chloride. Significant changes in the microbial community were observed after 180 days of incubation as well as in a continuous flow membrane reactor, using 16S rRNA gene PCR-denaturing gradient gel electrophoresis, 454 pyrosequencing, and

Chemical bath deposition of CdS thin film for solar cells was investigated in this study. CdS thin films were prepared by chemical-bath deposition (CBD) from a bath containing cadmium acetate, ammonium chloride, ammonium hydroxide and thiourea in aqueous solution on the glass substrate at certain bath temperature. The characterization of samples was conducted by using different methods such as scanning electron microscopy (SEM), X-ray diffraction (XRD) and ultraviolet spectrophotometry (UV). The crystal quality of CdS thin films was improved after CdCl2 thermal annealing at 400C. The results s

One novel, simple and convenient synthetic approach has been proposed to prepare the porous molybdenum disulfide materials by utilizing ammonium tetrathiomolybdate as the precursor and sodium chloride as the template. The as-synthesized products were characterized by X-ray powder Diffraction (XRD), Low-temperature N2 Adsorption (BET method), and Scanning Electron Microscopy (SEM). The characterization results reveal that the as-synthesized molybdenum disulfide material has high specific surface area (253.5 m2/g).

In a one-step thermal process using 2-[(methacryloyloxy)ethyl]trimethylammonium chloride (META), an ammonium polymer was successfully obtained for the removal of anions (nitrates, nitrites, and phosphates) from aqueous solutions. Ethylene dimethacrylate (EDMA) was used as a cross-linking agent. The effect of cross-linking agent, porogen, and polymerization time on the structure and physical properties of the obtained polymer was examined (FTIR, SEM, BET, elemental analysis). The optimal conditions for META synthesis were a monomer to porogen ratio of 20:80, 75% functional monomer content and a

We use BC/TiO2 membrane as substrate by introduced quaternary ammonium groups to prepare BC/TiO2/CHPTAC (3-chloro-2-hydroxypropyl trimethyl ammonium chloride) composite membranes. The as-prepared composite membrane was characterized by XRD, SEM, XPS, and TG methods.

The discharging of ammonium from industrial, domestic, and livestock sewage has caused eutrophication of the water environment. The objectives of this study are to synthesize magnetic zeolite (M-Zeo) by an eco-friendly, economical, and easy procedure and to investigate its suitability as an adsorbent to remove ammonium from an aqueous solution. Based on characterization from XRD, BET, and SEM-EDS, Fe3O4 was proved to successfully load on natural zeolite. The effect of pH, temperatures, reacting times, initial ammonium concentrations, and regeneration cycles on ammonium adsorption was examined
