The picture above shows bread mold which is a type zygospore fungi. These fungi produce spores in the black stalk-like structures you can see in the picture.
Wootz steel is a steel characterized by a pattern of bands or sheets of micro carbides within a tempered martensite or pearlite matrix. It is the pioneering steel alloy matrix developed in South India in the sixth century BC and exported globally.It was also known in the ancient world as Seric Iron.ral tradition in India maintains that a small piece of either white or black hematite (or old wootz) had to be included in each melt, and that a minimum of these elements must be present in the steel for the proper segregation of the micro carbides to take place.
Diamagnetic Metals. The term diamagnetic is a more technically accurate way of describing a material that is not attracted to a magnet. The atoms or molecules of a diamagnetic substance do not have net dipole moments, so they do not act as magnets.A diamagnetic substance is pushed out of a magnetic field, but with most materials the force is so weak you won't be able to observe it in everyday life. Diamagnetic metals include copper, silver and lead.he atoms or molecules of a diamagnetic substance do not have net dipole moments, so they do not act as magnets.
