IBM researchers used a new nanopatterning technique to create the "world' smallest" 3D map of the Earth. Approximately 1000 of them would fit on a single grain of salt. Separately, they also carved out a 25-nanometer tall model of the Matterhorn. A nanometer, of course, is one-billionth of a meter, so that's a 1:5 billion scale nano-mountain.
From IBM Research:
The core component of the new technique, which was developed by a team of IBM scientists, is a tiny, very sharp silicon tip measuring 500 nanometers in length and only a few nanometers at its apex...
The tip, similar to the kind used in atomic force microscopes, is attached to a bendable cantilever that controllably scans the surface of the substrate material with the accuracy of one nanometer–a millionth of a millimeter. By applying heat and force, the nano-sized tip can remove substrate material based on predefined patterns, thus operating like a "nanomilling" machine with ultra-high precision.
The video conferencing app Zoom has become suddenly ubiquitous over the past few weeks, as the coronavirus shutdown closes schools, businesses, and keeps us all indoors. Shares of Zoom dropped 9% on Monday, adding to their sharp declines in recent days, as security and privacy vulnerabilities are reported. There is also new competition from other […]
Canada’s prime minister Justin Trudeau says the country has signed an agreement with Amazon.com for the distribution of critical emergency medical supplies such as masks, face shields, gowns, ventilators, and test kits in the COVID-19 crisis.
In baseball, utility players often stay employed almost exclusively because of their versatility, their ability to slide effortlessly into a variety of needed roles and remain productive. Your current tech setup doesn’t need to work any differently — except that tech items are usually created to fulfill just one purpose. But if you want a […]
While all the downsides of stay-at-home orders and social distancing are evident, there are at least a few small silver linings to come out of all this. For many, this time spent indoors has meant a happy reintroduction to your very own kitchen. You know your kitchen. It’s usually the place that holds all your […]
Have you ever had more time to hone in on fine details than right now? Sure, at first glance, this might not seem like the time to get tripped up on the nitty-gritty of minutia. But how often are you ever going to have this much time to really stop and think about hows and […]
