This paper presents the study on aluminium-doped zinc oxide (AZO) films prepared by atmospheric atomic layer deposition (AALD) using Diethylzinc (DEZ), Zn(C2H5)2, and Trimethylaluminum (TMA), Al(CH3)3 as precursors. The optimal condition for doping was investigated by changing in DEZ/TMA ratio.

Zero-valent iron (ZVI)- and zero-valent aluminium (ZVA)-activated persulfate (PS) oxidation procedure was applied to remove the industrial pollutants 3,5-dichlorophenol (3,5-DCP; 12.27 µM) and 2,4-dichloroaniline (2,4-DCA; 12.34 µM) from aqueous solutions. The effects of PS concentration and pH were investigated to optimize heterogeneous treatment systems. Negligible removals were obtained for both pollutants by individual applications of nanoparticles (1 g/L) and PS (1.00 mM). PS activation with ZVI resulted in 59% (1.00 mM PS; 1 g/L ZVI; pH 5.0; 120 min) and 100% (0.

TiN-based coatings have been used widely for protecting surface of various application fields due to their superior properties such as high hardness, low friction coefficient, and low wear rate. Indeed, adding aluminium (Al) into the TiN coatings would further increase their hardness and oxidation resistance.

=Total Phenolics (TP) including Flavonoids were extracted from eight varieties grown through Conventional and Organic farming system of rice at Norman E. Boralog Crop Research Centre of G.B.P.U.A. & T., Pantnagar (U.K.) India. Extraction of TP including Flavonoids was carried out using 70% (V/V) ethanol at 25ºC.

In this study, the alkaline solutions (NaOH) with concentrations from 1M to 18M, red mud (RM) and silica fume (SF) were used as reactors in geopolymer reactions. RM contains 7.40% SiO2 and 13.65% Al2 O3 and SF has 94.50% SiO2 , but only the active oxides can participate in the geopolymer reactions. The activity of the oxides was investigated by determining the compressive strength of the samples under different curing conditions.

Petroleum contaminant decomposition and in-situ destruction may be accomplished using chemical oxidation technologies. In contrast to other remedial technologies, contaminant reduction can be seen in short time frames (e.g., weeks or months). As discussed in this chapter, a variety of chemical oxidants and application techniques can be used to bring oxidizing materials into contact with subsurface contaminants to remediate the contamination.

Sắc kí lớp mỏng (thin layer chromatography - TLC) là một kĩ thuật sắc kí được dùng để tách các chất trong hỗn hợp[1]. Phương pháp sắc kí lớp mỏng bao gồm pha tĩnh là một lớp mỏng các chất hấp phụ, thường là silica gel, aluminium oxide, hoặc cellulose được phủ trên một mặt phẳng chất trơ. Pha động bao gồm dung dịch cần phân tích được hòa tan trong một dung môi thích hợp và được hút lên bản sắc kí bởi mao dẫn, tách dung dịch thí nghiệm dựa trên tínhphân cực của các thành phần trong dung dịch....
