This study investigates the effect of highly fluorinated electroslag with TiO 2 content 0%, 3%, 6% and 9% on melting process, crystallisation kinetics crystalline product structure by using STA, XRD SEM-EDS techniques. The results demonstrated a gradual decrease in temperature, heat fusion first temperature slag as increased. main precipitation phases are Ca 12 Al 14 O 32 F , CaF CaZrO 3 CaTiO (Ca, Zr, Ti)O MgO. larger ratio :ZrO higher rate multi-faceted . dendritic was also gradually...
A simple and reliable method was established for simultaneous determination of 4-hydroxyphenyl acetic acid, lactic 3,4-hydroxyphenyl propionic acid in human urine by high-performance liquid chromatography with fluorescence detection. Solid-phase extraction used to eliminate the interferences urine. The separation three analytes achieved using a C18 column mobile phase formed 95:5 v/v mixture 50 mmol/L ammonium acetate buffer at pH 6.8 that contained 5 tetrabutyl bromide acetonitrile. Under...
Experimental investigations on the heat transfer characteristics of an oscillating-flow pipe with acoustic cavitation in comparison ordinary are given this article. The experimental results showed that rate field imposed evaporator section was higher than without a by 8–24.5%. It has been proved can enhance performance pipe. However, for case applied condenser section, not all ultrasonic fields were effective, and increased from −39 to 77%. Further discussion is provided.
Adsorption of phosphate onto construction solid waste (CSW) was investigated in a batch system. CSW as an inescapable by-product the and demolition process, used composite adsorbent for removal this study. The adsorption kinetics under various parameters such contact time, pH, dosage, initial concentration particle size. Greater percentage removed with decrease increase amount used. pH dependent, maximum immobilisation capacity obtained alkaline condition. Lagergren first-order, second-order,...
A non-ionic water-soluble galactomannan, isolated from the seed endosperm of Crotalaria mucronata Desv., may be an ideal thickener to increase food viscosity. The present study hypothesized that viscous property galactomannan associated with its spatial structure. Therefore, structure was elucidated using atomic force microscope. results demonstrated polysaccharide consisted a D‑mannose backbone D‑galactose branches, and D‑mannose/D‑galactose ratio 2.375:1. In three‑dimensional helix common...
A novel, simple, rapid, and accurate method is reported for the determination of 4-hydroxyphenyllactic acid in human urine by high-performance anion-exchange chromatography with fluorescence detection magnetic solid-phase extraction. The separation pretreatment conditions were optimized. isolation was performed isocratic elution 4 mmol L−1 sodium hydroxide at 0.45 mL min−1. Fluorescence an excitation wavelength 277 nm emission 340 nm. Under optimized conditions, linear dynamic range limit...
In this paper, a fast and reliable method was developed for simultaneous quantification of tyrosine, 4-hydroxyphenyl acetic acid, lactic 3-4-hydroxyphenyl propionic 4-hydroxyphenethyl amine alanine in human urine by ultra-high performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UHPLC-Q-TOF-MS). The sample preparation procedure simplified to obtain analysis terms diluting the ultrapure water centrifuging pre-analysis. After estimating matrix effect,...
SnxSy thin films were prepared by a two-step process. This process includes deposition of Sn on glass substrates thermal evaporation and sulfurization in vacuum condition at different temperatures 150~300° for 45min. The microstructures, composition photoelectrical properties the investigated. results show that, there are some differences structure, phase morphology synthesized temperatures. All p-type conduction. With increase temperature, Hall mobility carrier concentration increased,...
MnO x has become a focus in the research of low-temperature SCR De-NO catalysts for its good catalytic activity.Many -based have been researched which all high selectivity N 2 and anti-poisoning, but most them lack enough clear reaction mechanism kinetic.In this paper, progress mechanisms kinetics were summarized.The are NH 3 as reducing agents active centres.The overall can be explained by L-H, E-R Mars-van Krevelen mechanisms.H O SO deactivation also mentioned.The at studied based on power...
