Scientists from the Massachusetts Institute of Technology have resorted to the help of nanotechnology to create a new generation of armor, which, according to them, is superior to Kevlar and steel.
A new understanding of the complex architecture of the lobster's lower abdomen has provided engineers at the Massachusetts Institute of Technology with a model of a new rigid and elastic hydrogel. The material mimics the spiral structure of the creature's natural armor, which gives it greater strength and tear resistance.
By the decision of the UNESCO General Assembly, 2019 was declared the International Year of the Periodic Table of Chemical Elements. 150 years ago, in February 1869, Dmitry Mendeleev sent out a draft to his colleagues briefly outlining the essence of the new law, and on March 6, Nikolai Menshutkin read his report to the Russian Chemical Society.
A few years ago, archaeologists discovered a fragment of a Spanish pistol at an excavation site in Colorado, the true age of which became known only recently. This means that the Spanish colonists carried out forays into the territory of modern Colorado 100 years earlier than scientists believed.
Metal foams are a very lightweight and surprisingly durable material. So durable that it can even stop an armor-piercing bullet, turning it into dust when it collides.
