There are few applications in which materials quality is more important than in the production of polycarbonate ophthalmic lenses. The slightest variation from perfection can alter the prescription ...

If you stretch an elastic band, it becomes thinner - a physical behavior that applies to most "common" materials. Since the 20th century, an opposite behavior has been known in materials research: The ...

The artificial construction of anisotropic deforming materials is one of the great challenges in materials and polymer chemistry. In this paper, we demonstrate a unidirectionally deformable material ...

Lithium-ion batteries are a kind of rechargeable battery that is charged or discharged through desorption or insertion of lithium ions (Li +) from or into the active material structure. In recent ...

In my previous column, I discussed the influence of column buckling of the composite material test specimen on its measured compressive strength (see "Buckling of composite material compression ...
