Scientists at Rice University have succeeded in creating graphene through a "highly renewable" and common resource, which is wood! In 2014, a team of chemists led by James Tour developed a process for fabricating 3D graphene foam by heating a polymer surface with a laser, which is called “laser mutagenesis graphene†( Laser-induced graphene), abbreviated as LIG. Now, they have used this technology in the latest research results.
The new process is called "pine laser-induced graphene" (P-LIG for short)
New Atlas pointed out that the problem with LIG is that only a specific type of plastic (Polyimide) can be used until Rice University's research team realizes that certain woods (such as Pine/Pine) have similar mechanical structures.
Based on this, they used industrial lasers to heat a piece of pine (in an oxygen-free environment), which turned the wood surface into graphene foam. After continuous trial and error, they found that 70% of the laser energy is best suited to induce the conversion of pine wood to graphene.
Although there is still a long way to go from commercial use, the research team hopes that the technology will one day help reduce the growing problem of e-waste. Details of this research have been published in the recently published Academic Journal of Advanced Materials.
Expanded metal is a versatile and economical product made from a high-quality sheet of aluminum, steel, galvanized steel or stainless steel that is uniformly slit and stretched. This forms a diamond-shaped pattern of openings in the metal sheet.
Aluminum Expanded Metal Mesh is a type of expanded metal that is made from a sheet of aluminum. It is light, durable, and corrosion-resistant. This type of expanded metal is often used in architectural applications, such as window screens, room dividers, and decorative accents.
Expanded Metal Sheet is a broad term that refers to any type of expanded metal, regardless of the material from which it is made. These sheets are available in a variety of thicknesses and sizes, and they can be used for a wide range of applications, from industrial to decorative.
Expanded Metal for Construction is a type of expanded metal that is designed for use in construction applications. It is often used as a sturdy, lightweight material for walkways, ramps, and platforms. It can also be used as a reinforcement material in concrete and other construction projects. This type of expanded metal is typically more durable and has a higher load-bearing capacity than other types of expanded metal.
