Theory of Fighting Pathogens with Pathogens Is Homeopathy A Credible Treatment? Around 1790‚ Samuel Hahnmann‚ a German physician took in a certain amount of quinine from the bark of Cinchona sp. which was usually used to treat malaria (the main symptom is fever) and later he noticed some effects such as his body temperature raised. With further study‚ he concluded the theory that a substances cause disease symptom can also alleviate the disease which later developed to be “Homeopathy” treatment

Abstract The photocatalytic degradation of phenol has been tested primarily with titanium dioxide (TiO2) either alone or in combination with other materials. In this work‚ Mg/Al hydrotalcites prepared by two methods using inorganic (HC) or organic (HS) chemical reagents‚ along with mixed oxides produced by calcination of these products (HCC and HSC) were mixed with titanium isopropoxide to obtain hydroxide-TiO2 compounds (HCC-TiO2 and HSC-TiO2) to test their photocatalytic activity compared with

1.1 Definition Nanochemistry is concerned with generating and altering chemical systems‚ which develop special and often new effects as a result of the laws of the nanoworld. The bases for these are chemically active nanometric units such as supramolecules or nanocrystals. Nanochemistry looks set to make a great deal of progress for a large number of industry sectors. Nanotechnology exists in the realm where many scientific disciplines meet. Achievements in physics are getting progressively

Evaluation of the effects of Ag exchanged zeolite nanocomposite on excisional wound healing in rats. Introduction Skin is often injured by wounding or physical trauma. Damages to skin initiate a series of complicated and well-orchestrated events of repair processes ending with complete reestablishment of the penetrate deep in the skin remain a major clinical problem because of morbidity associated with prolonged periods required for repair and regeneration of the injured tissue‚ bleeding‚ risk for

Topic: Silver is an ancient mineral that dates back since prehistoric times. One thing that makes silver so special is that it was one of the first five metals that we started to use. Silver is found in almost every electronic device there is‚ and as time progresses the usage of it increases‚ unfortunately the amount there is left decreases. How is it created or source of the mineral? (5) Silver is not originated from Earth‚ as it happens it came from space. Many elements were formed in the big

3.2 “Lab-on-a-Chip” A Lab-on-a-Chip (LOC) device‚ also known as a micro-total-analytical system (microTAS) or microfluidics device‚ is a device that can integrate miniaturized laboratory functions (such as separation and analysis of components of a mixture) on a single microprocessor chip using extremely small fluid volumes on the order of nanoliters to picoliters. From a technology categorization perspective‚ LOCs can be viewed as a subset of microelectromechanical systems (MEMS) and combine

Previously‚ the electrode is modified with noble metal nanoparticles such as Pd‚ Pt and Au. Among the Pd‚ Au and Pt‚ Au has good prospect and choose to determine uric acid due to unique structure and excellent conductivity. Furthermore‚ the method such as capillary electrophoresis and high performance liquid chromatography
