Finding out if the food and water we consume are safe from toxic and carcinogenic metals can now be much faster and simpler. Researchers at the University Johannesburg developed an efficient and more ...

Sheet metal forming operations can vary greatly in their processes. From simple bending to stretching to deep drawing of complex parts, sheet metal forming operations may take many forms. Image Credit ...

A material’s hardness relates to its mechanical resistance when subjected to mechanical indentation by another harder body. Diamond is considered the hardest natural material and is typically used for ...

In 1905, the U.S. Pharmacopeial Convention, the nonprofit standards-setting organization known as USP, introduced a method to check for heavy metals in U.S. pharmaceuticals. More than 100 years later, ...

When metallic components in airplanes, bridges, and other structures crack, the results are often catastrophic. But Johns Hopkins University researchers have found a way to reliably predict the ...

Mechanical fasteners have been used to join wood and metal plates for hundreds of years. Because mechanical fastening of composite material plates is a much more recent development, most of the ...

Limestone composition and reactivity are critical factors that determine the performance of limestone-based wet flue gas desulfurization systems. Limestone quality affects sulfur dioxide (SO 2) ...

Until the early 1970s, there was relatively little interest in measuring the compressive properties of composite materials. For design purposes, it was generally assumed that the compressive strength ...
