Molybdenum can increase steel`s
corrosion resistance in the acid-based solutions and liquid metals, thus
improve its wear resistance, hardenability, weldability, and heat resistance.
As an element which easy to form carbides, molybdenum can effectively avoid
oxidation during steel making process, and it can be used alone or mix with
other alloy element to achieve the best performance.
A pure molybdenum rod is a cylindrical bar made entirely of molybdenum, a chemical element with the symbol Mo and atomic number 42. Molybdenum is a refractory metal known for its high melting point, excellent thermal conductivity, and resistance to corrosion. Pure molybdenum rods are commonly used in various applications, including the manufacturing of electrodes, heating elements, and high-temperature furnaces. They are also utilized in the aerospace, defense, and medical industries due to their exceptional mechanical and thermal properties.

Streptococcus suis is the main cause of bacterial meningitis in adults in Southeast Asia and pigs around the world.
Almost every pig carries a harmless strain of this bacterium. But another type of this bacterium is more deadly. They can cause disease in pigs around the world and also promote the use of antibiotics.
This deadly strain is also increasingly associated with serious human diseases such as meningitis and sepsis.
International studies have found that harmless strains and pathogenic strains are genetically different. Strains that can cause disease have 50-100 fewer genes than symbiotic bacteria.
The first author of the study, Dr. Lucy Weinert of the Department of Veterinary Medicine of the University of Cambridge, said: "The reduction in genes of this strain is related to its pathogenic characteristics."
By studying the evolution of Streptococcus suis, researchers have discovered that the strains that can cause meningitis in pigs and humans first appeared in the 1920s.
The emergence of this strain coincided with the time when the large-scale indoor pig breeding model began to be promoted. This breeding method is supported by the government and is beneficial to large producers with stable production capacity.
Duncan Maskell, director of the School of Biological Sciences at the University of Cambridge, said: "Human Streptococcus suis disease is rare in the West, but it occurs more frequently in East Asia.
It is most likely to be spread to humans due to poor food hygiene habits or other environmental factors. This highlights the importance of monitoring food regulations and implementing policies to reduce mutual infections between different species. "

According to reports, changes in breeding methods may cause pig disease to spread from person to person
[China Native Pig Trading Network] According to reports, international media reported on April 2, 2015 that a new study from the University of Cambridge found that pig breeding has changed to large-scale indoor group breeding and bacterial meningitis (a kind of Diseases that can affect pigs and humans at the same time) appear at the same time.
