KNN piezoelectric ceramics are of great importance in the field scientific research due to their high Curie temperature, good electrical properties, etc. The application potassium sodium niobate K0.5Na0.5NbO3 (KNN) is strictly limited volatility Na+ and K+ its leakage current. In order investigate effect Mn doping on KNN-based ceramic coatings, KNN-0.02Mn (KNMN) coatings were successfully prepa...

Green bactericides are excellent strategies for reducing food spoilage. Phloretin was regarded as efficient, broad-spectrum and safe preservative, which showed enormous potential in industry. Inhibitory mechanism of phloretin on Listeria monocytogenes systematically elucidated through integrity cell membrane, intracellular protein content, energy level, nucleic acid morphological character. SEM...

The catalytic inactivation of Escherichia coli (E. coli) in water by silver loaded alumina as catalyst was investigated. Ag/Al(2)O(3) and AgCl/Al(2)O(3) catalysts exhibited high bactericidal activity at room temperature in water with no need for any light or electrical power input. Dissolved oxygen which can be catalyzed to reactive oxygen species (ROS) was found to be essential for the strong ...

Experiments have been performed to determine some of the factors affecting the release of intracellular enzymes, in the hope of improving our understanding of the mechanisms whereby tissue enzymes reach the circulation in disease processes. The discharge of intracellular enzymes into the medium during prolonged incubation of human leukocytes and rat lymphocytes has been shown to be inversely re...

Among the electrophysiological properties differentiating stratum oriens horizontal interneurons from pyramidal neurons of the CA1 hippocampal subfield are the more depolarized resting potential and the higher input resistance; additionally, these interneurons are also less sensitive to ischemic damage than pyramidal cells. A differential expression of pH-sensitive leakage potassium channels (T...

Inhalation therapy using essential oils has been used to treat acute and chronic sinusitis and bronchitis. The aim of the present study was to determine the chemical composition of the essential oil of Artemisia capillaris, and evaluate the antibacterial effects of the essential oil and its main components, against common clinically relevant respiratory bacterial pathogens. Gas chromatography a...

irrigation with distillery effluent, besides influencing crop yield, may have considerable impact on physical properties of soil because of its high salt and organic carbon contents. this experimental study was conducted to evaluate the effect of distillery effluent on hydraulic conductivity of a sandy loam alluvial soil and compare the effect of inorganic salts of potassium (k) with that of di...

Objective: Fruits of lemon pepper (Zanthoxylum acanthopodium DC., Rutaceae) have been traditionally used as a spice and in folk medicine for treatment of diarrhea and stomachache. Stomachache could be associated with mycobacterial infection. The present study was designed to investigate the activity of Z. acanthopodium fruits against a non-infectious Mycobacterium smegmatis and to identify the ...

nitration of potassium sulphamate was carried out using a mixture of sulphuric and nitric acid at -30 °c. the reaction time was optimized at the mole ratio of sulphuric to nitric acid of (1:3.5). the difference in product yield by changing the potassium to ammonium sulphamate was studied throughly. it was found that both the yield and purity of the product is better starting with potassium sulp...
