Abstract:

Optimal conditions for the synthesis of sodium perborate are proposed through the chemical interaction of sodium tetraborate, hydrogen peroxide and sodium hydroxide in a peroxide environment. Based on the data of chemical analysis and physicochemical studies, its identification was carried out, it was established that the stoichiometric composition of NaBO3•4H2O depends on the concentration of the initial reagents and the synthesis temperature. Using thermogravimetric, X-ray phase analysis and IR spectroscopy methods, thermoanalytical studies of tetrahydrate crystalline hydrate were carri

Abstract:

AbstractFor selecting the most efficient treatment method of hospital waste, the composition analysis is generally considered to be the fundamental information. Currently, there are few studies regarding the characteristics of hospital waste. This study evaluated the physical and elemental composition of the hospital waste at the National Taiwan University Hospital (NTUH). The results should help us design an incinerator for the treatment of infectious waste, plastic syringes, pathological waste, and kitchen waste. During the study period, the estimated daily waste generation rate at NTUH was

Abstract:

In this work, soil corrosivity of the central desert of Iran was investigated by analyzing the physical-chemical characteristics of soils, weight loss testing, and electrochemical measurements. The most important factors affecting soil corrosivity that have been considered in this study are electrical resistivity, pH, redox potential, sulfides, moisture, soluble salts, chlorides, and cations content. The corrosion rate of soil in different areas of the central desert of Iran is in the range of 0.029 to 0.097 mm/y and 0.037 to 0108 mm/y with respect to field and laboratory corrosion experiments

There were four treatments included P0 (control feed), P1 (control feed + 10% Pomacea canaliculata meal), P2 (control feed+20% Pomacea canaliculata meal), P3 (control feed + 30% Pomacea canaliculata meal). The variables observed included final body weight, carcass weight, carcass yield, non-carcass weight, meat chemicals composition and haematological profile. The experimental design used a completely

Abstract:

This article provides an in-depth study of the chemical and mineralogical composition of kaolin raw material from the Karnab deposit, its industrial applications, and beneficiation methods. The article describes effective techniques for removing harmful impurities present in Karnab kaolin, such as iron and titanium oxides, as well as alkali and alkaline earth metal oxides. The kaolin is bleached and its physical and optical properties are improved through the use of various chemical reagents (e.g., sulfuric, hydrochloric, and organic acids), flotation, hydrothermal, and autoclave processing te

Abstract:

Clay material from Rendeng, Malo, Bojonegoro was studied by mineralogy and physicochemical characterization to evaluate its potential suitability as a raw material in pottery application. X-ray Diffraction (XRD) and Fourier Transform-Infrared (FTIR) spectrometry were used to establish the mineralogy composition. Meanwhile the physical properties were identified by particle size distribution and consistency limits. Chemical composition was carried out by X-ray Fluorescence Spectrometer (XRF). The results of XRD characterization revealed that clay from Rendeng Village, Malo, Bojonegoro contained

Abstract The problem of the internal structure of the Moon plays a special role in understanding its geochemistry and geophysics. The principal sources of information about the chemical composition and physical state of the deep interior are seismic experiments of the Apollo expeditions, gravity data from the GRAIL mission, and geochemical and isotopic studies of lunar samples. Despite the high degree of similarity of terrestrial and lunar matter in the isotopic composition of several elements, the problem of the similarity and/or difference in the major-component composition of the silicate s

Abstract:

AbstractSprings, or points of natural, concentrated groundwater discharge, may be located in river or lake beds, or below mean sea level along the coast, but many are found some distance from surface-water bodies. Spring water commonly represents rain or snow-melt that has entered the ground at a higher elevation a number of years earlier.Measured springwater temperatures in Canada range from very cold (−2.9 °C) to hot (82.2 °C). Thermal spring waters, with temperatures above the local mean-annual air temperature, have undergone geothermal heating during deep subsurface circulation in areas of

Background. Meteoroids can reach the Earth and penetrate its atmosphere creating meteor phenomena. Kinematic parameters, physical characteristics, and chemical compositions of the observed meteor bodies provide information about the properties of their parent bodies — comets and asteroids. On the other hand, these parameters can reflect the physical conditions of meteor- oids staying in different parts of the Solar System and beyond. Methods. The meteor data analyzed in this work were obtained from observations using the automatical video and spectral meteor patrol (AVSMP) of the Institute of

Abstract A special nano-composition of biodiesel was created that can increase the storage capacity and quality stability of the biodiesel fuel. The group compositions of pure nano-biodiesel and its blends with mineral diesel fuel were analyzed using a Fourier Infra Red (IR) spectrometer, and the individual hydrocarbons were identified by a gas chromatograph. The group compositions and physical and chemical parameters of the nano-biodiesel fuel fully met the standards and remained stable from 2018 through 2021, proving that this type of biodiesel can be stored for more than 4 years while maint
