A method is developed for detection of polycyclic aromatic hydrocarbons (PAHs) and Phthalic Acid Esters (PAEs) in soil samples. Ultrasonic Wave Extraction under airtight circumstances is adopted to ex...
Dimethyl ether (DME) is amongst one of the most promising alternative, renewable and clean fuels being considered as a future energy carrier. In this study, the comparative catalytic performance of th...
To utilize starch and protein contained in microalgae as carbon and nitrogen sources for ethanol production, an extraction method, i.e. ultrasonic treatment using a homogenizer, and simultaneous sacch...
Several experimental candidates for quantum spin liquids have been discovered in the past few years which appear to support gapless fermionic S = 1 2 excitations called spinons. The spinons may form ...
The integration of high-resolution, non-invasive geophysical techniques (such as ground-penetrating radar or GPR) with emerging sensing techniques (acoustics, thermography) can complement limited dest...
摘要 Excess volumes (VE), ultrasonic velocities (u), isentropic compressibility (∆Ks) and viscosities (η) for the binary mixtures of dimethyl formamide (DMF) with 1,2-dichlorobenzene, 1,3-dichloro...
Zinc oxide (ZnO) thin films have been prepared by ultrasonic Spray Pyrolysis (USP) technique using zinc acetate dihydrate dissolved in methanol, ethanol and deionized water. A thermodynamic analysis f...
The total conductivity of KHCO3 compound is studied in the frequency range 50 Hz-1 MHz and in the temperature range 300-370 K. The conductivity frequency dependence relation is divided into three regi...
A quick and convenient method for the preparation of 2-aminobenzophenone derivatives is described. This approach consists of the nucleophilic substitution reaction of nitrobenzenes by phenylacetonitri...
Real time ultrasound data was generated on 10,596 live Hanwoo cows to study genetic variation on ultrasonic beef quality traits and to assess the best model to estimate genetic parameters on these tra...
Real time ultrasonic measurements for 13th rib fat thickness (LBF), longissimus muscle area (LEMA) and marbling score (LMS) of live animal at pre-harvest and subsequent carcass measurements for fat th...
A method of ultrasonic leaching has been developed for the destructive analysis of magmatic rock samples1. This method was applied to determine three new elements, Ca, Mg and Al, in magmatic rock samp...
An in situ density profile has been measured with an ultrasonic density probe in the mining lake Merseburg-Ost 1b. From the acquired measurements of sound speed and acoustic impedance, the important p...
Determination of Manganese and Iron in Magmatic Rocks After Ultrasonic Leaching by flame AAS.
