A spring is made of steel and not copper. Why? Why aluminium wires used in the transmission of electrcity are not insulated? What are two reasons why zinc and potassium are unlikely to form a solid solution alloy? Why is it difficult to make mercury enter a fine thermometer tube?
Why aluminium wires used in the transmission of electrcity are not insulated? Why can't all materials become superconductors? What property makes metal a good conductor and rubber a good insulator? Why does elasticity increase when a material is hammered if material with smaller grains a...
Maraging steel is usedin aircraft, with applications including landing gear, helicopter undercarriages, slat tracks and rocket motor cases – applications which require high strength-to-weight material. Maraging steel offers an unusual combination of high tensile strength and high fracture toughness. ...
In aircraft, Monel is used for parts demanding bothstrengthand high resistance to corrosion, such as exhaust manifolds and carburetor needle valves and sleeves. K-Monel is a nonferrous alloy containing mainly nickel, copper, and aluminum. It is produced by adding a small amount of aluminum to t...
If the cause of the loading can be determined, the number of cycles to failure can then be used to estimate the time required for crack growth. Fatigue cracking is the most common cause of structural failure in aircraft, even though the laboratory fatigue behavior of most metals and alloys ...
The science-less claim that residual vaccines can be flushed from someone’s system had been a point of advocacy for years among the so-called “anti-vax” crowd, Nathan said, an idea built on the fact that older vaccines sometimes contained aluminium and mercury compounds in very low ...
Fungi have been companions of mankind for millennia. Mushrooms inspired our eating culture, and yeasts and filamentous fungi were developed into highly efficient cell factories during the last 100 years to produce many products utilized in different indu

Why is US interested in Ukraine’s raw materials? The US is seeking access to over 20 raw materials seen as strategically critical to its interests, including some non-minerals such as oil and natural gas. Among them are Ukraine’s deposits of titanium, which is used for making a...
