Water-soluble metal working fluids are used for processing of aluminum alloy materials. This short paper describes properties of new additives for water-soluble cutting fluids for aluminum alloy materials. Some alkyldiphosphonic acids were prepared with known method. Amine salts of these phosphonic acids showed anti-corrosion property for aluminum alloy materials. However, they have no hard wat...

X-ray powder diffraction methods have been more and more extensively used, in the last twenty years, in the characterization of different crystalline and non-crystalline materials of archaeological, historical, artistic interest. The present paper aims to discuss the use of these methods in studying different aspects related to the Cultural Heritage conservation. This purpose has been achieved ...

The breakthrough in biomedical and surgical instrument research follows the advances of newly developed biomedical technologies, improved composite materials, and renovated manufacturing methodologies. These new biomedical and surgical instruments allow physician to perform complex biomedical treatments and surgical operations with better medical quality. Some more complicated biomedical treatm...

Corrosion protection performance of a completely soluble polyaniline-dodecylbenzenesulfonic acid salt (PANI-DBSA) on C45 steel has been studied with electrochemical impedance and potentiodynamic measurements. Chloroform is the most suitable solvent to process the pristine PANI-DBSA because of negligible interaction of the solvent with the polyaniline (PANI) backbone. An anodic shift in the corr...

The corrosion protection of petroleum storage tank is important for safety work in petroleum depot. Precise prediction of soleplate corrosion may reflect the security state of a storage tank, and it can provide scientific references to the anti-corrosion and maintenance in safety management. Grey Model GM (1,1) in the Grey Theory is a good prediction method based on small volume of original dat...

Carotenoids are bio-pigments naturally available in many prokaryotic and eukaryotic microorganisms which cannot be synthesized biologically by one self including animal but, required for our basic nutritional supplement. Different types of carotenoid pigments are available with different colors especially yellow, orange, red, and purple etc. includes approximately 700 different types (Cabral et...
