A simple, time effective and cost effective, methos was reported for synthesis of nickel oxide nanostructure. The NiO nanostructure was synthesized by gamma-irradiation method from NiSO4 precursor. The solution was irradiated by 60Co gamma-ray source at the dose rate of 40 Gy/min for determined time. The synthesized powders are characterized by means of X-ray powder diffraction (XRD), Energy-di...

One solution to the high cost and scarcity of building materials is use alternative sustainable materials. The study presented herein developed an eco-friendly masonry grout using volumes palm oil clinker powder replace cement coarse aggregate. Several batches grouts with different amounts these were made determine technical viability grout. Scanning Electronic Microscope (SEM), X-Rays Diffract...

This study investigated the optimization of bioconcrete engineering properties and durability as a response calcium lactate (CL) content (0.22–2.18 g/L) curing duration (7–28 days) using surface methodology (RSM). Scanning electronic microscopy (SEM) was conducted to evaluate microstructure precipitated inside bioconcrete. The results indicated that optimal conditions for concrete were determin...

In this experimental research, an attempt is made to develop Al2214-B4Cp composite materials with reinforcement of micro boron carbide (B4Cp) (viz. 0, 1.5, 3, 4.5, and 6 wt.%) by using a novel liquid metallurgical stir casting technique modified bottom pouring facilities studying the microstructure, physical, mechanical, dry sliding wear resistance responses. The microstructure samples varied w...

Thermoluminecsence (TL) characteristics of pure CaSO4 nanoparticles produced by co-precipitation method are presented. The formation of the nanoparticles was confirmed by X-ray diffraction (XRD) and scanning electron microscope (SEM). TL glow curve of this phosphor, exposed to gamma radiation exhibits five overlapping glow peaks in the complex glow curve at 463, 470, 483, 498 and521(K) respecti...

This paper describes analytical and digital photogrammetric methods of a stereo pair of scanning electron microscope (SEM) photographs. Analytical method was applied to a triplet of stereo SEM photographs of an impression left by the diamond indenter of Vicker's hardness tester. The height error of the three dimensional measurement was ±5% and the precision is sufficient for surface shape analy...

in this work firstly fe3o4 nanoparticles were synthesized via a sono-chemical method. at the second step magnesium hydroxide shell was synthesized on the magnetite-core under ultrasonic waves. for preparation fe3o4-mgo the product was calcinated at 400 ºc for 2h. properties of the product were examined by x-ray diffraction pattern (xrd), scanning electron microscope (sem) and fourier transform ...
