New Method for Synthesis of Coatings of Molybdenum, Tungsten, Their Carbides and Composites
(Scientific Research, 2013-04)In this paper we report, for the first time, a new approach for synthesis of high quality faceted microcrystalline coatings of molybdenum (Mo), tungsten (W), their carbides and composites. These studies are carried out ... -
Non-thermal Influence of A Weak Microwave on Nerve Fiber Activity
(2014-10)This paper presents a short selective review of the non-thermal weak microwave field impact on a nerve fiber. The published results of recent experiments are reviewed and analyzed. The theory of the authors is presented, ... -
The Novel Pyruvated Glucogalactan Sulfate Isolated from the Red Seaweed, Hypnea pannosa
(Scientific Research Publishing, 2016-06)The polysaccharide was isolated from Hypnea pannosa which was grown in Okinawa, Japan. The yield of the polysaccharide was 17.2%, and the total carbohydrates, pyruvic acid, sulfuric acid and ash contents were 55.2%, 3.8%, ... -
A Novel Technique for Determination of Flow Characteristics of Blast Furnace Slag
(Scientific Research, 2012-06)A study of flow characteristics of blast furnace slag helps determine its softening and flow (liquid-mobility) temperatures. The slag with a narrow difference between the two temperatures is termed a “Short Slag”. Its ... -
On-Line Measurement of the Chemical Oxygen Demand in Wastewater in a Pulp and Paper Mill Using Near Infrared Spectroscopy
(Scientific Research, 2014-10)Although near infrared (NIR) spectroscopy has been evaluated for numerous applications, the number of actual on-line or even on-site industrial applications seems to be very limited. In the present paper, the attempts ... -
Optical and Electrical Properties of Nanocrystalline SnO2 Thin Films Synthesized by Chemical Bath Deposition Method
(Scientific Research, 2015-10)The chemical bath deposition (CBD) technique was used for the synthesis of the tin oxide (SnO2) thin films. X-ray diffraction (XRD) was employed to find the crystallite size by using Debye Scherrer’s formula. The surface ... -
Plant Cell Wall, a Challenge for Its Characterisation
(Scientific Research Publishing, 2016-06)The plant cell wall is a complex 3D network composed of polysaccharides, lignin and proteins. The knowledge of the structure and content of each cell wall polymer is a prerequisite to understand their functions during plant ... -
Possible Synergistic Effect and Antioxidant Properties of Chitosan Nanoparticles and Quercetin against Carbon Tetrachloride-Induce Hepatotoxicity in Rats
