Scientists at the University of Maryland, College Park, have developed see-through wood by removing the material that gives wood its yellowish color and then injecting the wood with epoxy to strengthen it.
The "invisible" wood -- as Dr. Liangbing Hu of the University's Department of Material Science and Engineering describes it -- is sturdier than traditional wood, and can be used in place of less environmentally friendly materials, such as plastics.
Samsung claims to have developed an “Ultra Thin Glass” for its new Galaxy Z Flip foldable smartphone, signalling scratch resistance and durability beyond that of similar products. But tests conducted by Zack Nelson using a Mohs Hardness Testkit [Amazon] — a set of styluses made of different materials — show that it is no more […]
It’s historically been tough and slow-going to 3D print objects made from multiple materials. Now, Harvard researchers developed an ingenious nozzle that enables the 3D printer to spew out eight different materials at the resolution of a human hair. To demonstrate the system, they printed fantastic flexible origami structures and even a “soft” robotic millipede […]
The US Air Force Research Laboratory (AFRL) has developed a new form of liquid metal with very strange conductive properties. Usually, when a flexible, conductive material is stressed or stretched, its electrical conductivity drops and resistance increases when it’s stress or stretched. Just the opposite, Air Force’s novel “Polymerized Liquid Metal Networks… can be strained […]
Back in the 50s and 60s, it was no big deal in most areas to make a call to your local liquor store and have beer, wine and spirits delivered right to your house with little to no restriction. However, that ease and simplicity certainly isn’t in place today. Alcohol delivery laws in 2020 are […]
Unless you’re a regular cannabis user, you might be surprised to learn that the plant itself is basically just that — a plant. It’s not until you put cannabis under high heat that the process of decarboxylation breaks down that raw form into the psychoactive compounds that can actually benefit the body. This unlocking process […]
With our smartphones serving as the vital tether that links us to the rest of our lives, it’s no wonder how low batteries and power emergencies can occasionally feel like a life-and-death situation. I mean, it’s usually not, of course…but darned if it doesn’t feel that way when your indicator is showing only 5 percent […]
