US military scientists have recently developed a transparent metal "clay" substance that can be used to make super-sturdy screens and monitors. In the future, people's mobile phone screens may have bulletproof functions, so you don't have to worry about the mobile phone screen falling on the ground.
This new material is made of spinel (MgAl2O4) composed mainly of magnesium and aluminum. It is stronger than bulletproof glass and lighter in weight. Researchers say it can also be used to protect aircraft, cockpits, and spacecraft. And satellite.
Scientists claim that the material can also be used to make scratch-resistant mirrors for cameras and smartphones to prevent the phone from falling when it falls on the ground. This transparent bulletproof material can also be used to make military lasers and infrared devices.
It is reported that after more than ten years of research and development, this material is to stamp and heat the nano powder to form spinel crystals, and then add mold processing.
Dr. Jas Sanghera, the U.S. Naval Research Laboratory responsible for this research, said that this material has better performance than bulletproof glass, which is a composite formed by special processing of glass and high-quality engineering plastic Type material, it can slow down the bullet speed.
He said: "If you use spinel instead, the weight of the bulletproof material will be reduced a lot." In addition, once the glass crystal structure shows cracks, it will continue to penetrate completely broken, compared with the spinel This is not the case with glass.
Spinel can be collected as a gemstone. The US Naval Research Laboratory can synthesize ultra-pure spinel powder and use a hot pressing process called "sintering" to make crystal flakes. It has been found that the material is very pure and can be used to make lenses for sensitive infrared cameras and laser equipment. (Author | Camera)
WATERPROOF Light Emboss SPC Flooring is the sound of what is sure to be the death nail to WPC (wood polymer composite) flooring as well as laminate flooring. SPC is a massive technical upgrade to WPC, wood composite core materials.
Light Emboss Spc Flooring can also be laid over most subfloors with little preparation. Unlike traditional vinyl floor that will highlight any unevenness present in the subfloor, the rigid core of SPC Flooring allows for longer and wider format options so you don't have to worry when installing over cracks or divots in subfloors
