From dot-matrix to 3-D, printing technology has come a long way in 40 years. But all of these technologies have created hues by using dye inks, which can be taxing on the environment. Now a team reports in ACS Nano the development of a colorless, non-toxic ink for use in inkjet printers. Instead of relying on dyes, the team exploits the nanostructure of this ink to create color on a page with inkjet printing.
In a new study, Hao Yan, director of the Center for Molecular Design and Biomimetics at Arizona State University's Biodesign Institute presents a clever means of localizing and confining enzymes and the substrate molecules they bind with, speeding up reactions essential for life processes.
An engineering research team at the University of Alberta has invented a new transistor that could revolutionize thin-film electronic devices. Their findings, published in Nature Communications, could open the door to the development of flexible electronic devices with applications as wide-ranging as display technology to medical imaging and renewable energy production. The transistor is easily scaled and has power-handling capabilities at least 10 times greater than commercially produced thin film transistors.
Since the discovery of the diffraction of X-rays by crystals just over 100 years ago, X-ray diffraction as a method of structure determination has dominated structural research in materials science and biology. However, many of the most important materials whose structures remain unknown do not readily crystallize as three-dimensional periodic structures.
Vitrified metals, or metallic glasses, are at the frontier of materials science research. But much about them remains poorly understood. A team is trying to figure out the rules that govern metallic glass's creation. They are doing this by looking at metallic glasses under extreme pressures. High-pressure research can be used to probe structure on an atomic level and understand a material's state of order or disorder.
A team led by engineers at the University of California, San Diego has 3-D-printed a tissue that closely mimics the human liver's sophisticated structure and function. The new model could be used for patient-specific drug screening and disease modeling. Researchers said the advance could help pharmaceutical companies save time and money when developing new drugs. The work was published the week of Feb. 8 in the online early edition of Proceedings of the National Academy of Sciences.
Scientists have created a crystal structure that boosts the interaction between tiny bursts of light and individual electrons, an advance that could be a significant step toward establishing quantum networks in the future.
Pollens, the bane of allergy sufferers, could represent a boon for battery makers: Recent research has suggested their potential use as anodes in lithium-ion batteries.
The way to better wearable electronics is dotted with iron steppingstones. Check out how Michigan Tech researcher Yoke Khin Yap's nanotubes bridge the gap with quantum tunneling.
Scientists have for the first time reengineered a building block of a geometric nanocompartment that occurs naturally in bacteria to give it a new function.
