When it comes to 3D printing, the sky is the limit. As 3D printing technology continues to advance, applications can be as far reaching as airplane and automobile parts to medical devices and even anatomically correct, biocompatible models. Although 3D printing technology is developing at a rapid pace, the technology itself is not new. It emerged in the 1980s as a means of creating rapid prototypes. In recent years the applications for 3D printed models have evolved with the available hardware, software, and printable materials. Evolving technology, paired with the creative and innovative minds of scientists, engineers, and physicians, has been the launching pad for developments within 3D printing technology specific to healthcare. One way 3D printing technology is poised to create better patient outcomes is in creating an anatomically and patient-specific models to aid in surgery and medical procedures. With the capability to 3D ...
Who would have thought that a shell could spark what has been hailed by many scientists as the “next technological revolution.” By mimicking structures found in mollusks, scientists have created a transparent plastic that is as strong as steel.
Plastic nanotechnologies are built one nanoscale layer at a time. The process is similar to the way that mother-of-pearl, oyster and other mollusk shells grow. When the nanosheets are arranged in a brick-and-mortar structure, the final product is thinner than a strand of human hair but millions of times stronger.
These advancements in plastic nanotechnology reverberate widely. During the last decade, scientists have hoped to substitute polymers for the ultra-pure and very expensive silicon material used to make computer chips.
Plastic chips might soon be used in consumer electronics to drive flexible displays and keyboards and even changeable electronic wallpaper. Imagine that when you turned off your wall-sized television screen, a wallpaper pattern would appear to camouflage it. This is the future of nanotechnology in the living room.
Other possible applications include smart train and bus tickets and radio identification tags used to keep track of parts in factories or goods in stores.
Researchers also hope to develop improved polymer solar cells using nanomaterial additives. Labs across the country and abroad are currently experimenting with thin polymer film that can be rolled out in sheets. The film contains nanoscale pieces of semiconductor material and single-walled carbon nanotubes that maximize light to energy transfers. In layman’s terms, these ultra-thin, flexible sheets of plastic convert more of the sun’s rays into clean, inexpensive energy.
Most importantly, these sheets of film can be cut up and reused even if they have been bent. This is a marked contrast to rigid silicon cells that are easily cracked and expensive to replace.
