Making Materials That Repel All Liquids

Making Materials That Repel All Liquids 

 Water (dyed blue) and hexadecane (dyed red), an oil, bead up on an omniphobic surface, which repels all liquids.

Materials under development at MIT could lead to coatings that repel both water and oil. A group of MIT researchers have created an improved set of design rules for making any surface impervious to any liquid, be it water or gasoline. Such materials could eventually have promise as fingerprint-repelling coatings, fuel filters, self-washing car paints, and stain-resistant clothing.

World’s Most Powerful Electron Microscope

World’s Most Powerful Electron Microscope 

 Titan 80-300 Cubed Microscope

The Hubble telescope has a competitor. It’s not a telescope, but a microscope. The competition isn’t looking for stars and galaxies, but seeking atomic levels instead. McMaster University Canada has installed the world’s most powerful electron microscope at its Center for Electron Microscopy. Built in the Netherlands, the Titan 80-300 Cubed microscope is the planet’s most powerful and advanced microscope.

Nano-Structured Bone Graft Encourages Cell Growth

Nano-Structured Bone Graft Encourages Cell Growth 

 FortOss – Nano-Structured Bone Graft

Bone grafts can more closely mimic the chemical structure and composition of natural bone, thanks to a new material. Like other synthetics, the material minimizes the risk of immune rejection, but it’s much better at encouraging cells to grow.

Helmet Patch To Measure Soldier’s Exposure To Explosions

Helmet Patch To Measure Soldier’s Exposure To Explosions 

The Palo Alto Research Center is using ink-jet printing technology to develop a disposable patch that can be worn on a soldier’s helmet for seven days to measure his or her exposure to blasts. 

Researchers are developing a cheap, lightweight plastic strip that can be worn on a soldier’s helmet to help diagnose brain injury.

Japan Space Elevator Association To Draw Up Timetable For Space Elevator

Japan Space Elevator Association To Draw Up Timetable For Space Elevator 

The idea of a space elevator made of ultra-strong carbon nanotubes has been talked about a lot over the past several years, but recently some research groups have begun to investigate the idea as a real possibility. Most recently, scientists from Japan have started an organization called the Japan Space Elevator Association, and they plan to host an international conference in November to draw up a timetable for the machine.

Scientist Discovers Cure For Smelly Feet

Scientist Discovers Cure For Smelly Feet 

 

Nano-technology or nano-tech, refers to a field of applied science whose theme is the control of matter on an atomic and molecular scale. It concerns structures that are 100 nanometers or smaller and involves developing materials or devices within that size range. Inventor, Vladimir Rudenov, claims that he has developed a cure for smelly feet involving the weaving of silver nano-fibers into socks. His attempts to channel his small business into the wave of Russia’s burgeoning nano-technology industry has transformed his invention and his company into a national success story.

Nanonets Could Convert Sunlight Into Hydrogen

Nanonets Could Convert Sunlight Into Hydrogen

The top image shows a nanonet magnified 50,000 times. At bottom, a
flexible nanonet rolls up when poked by the tip of a scanning tunneling microscope.

One problem with solar cells is that they only produce electricity during the day. A promising way to use the sun’s energy more efficiently is to enlist it to split water into hydrogen gas that can be stored and then employed at any time, day or night. A cheap new nanostructured material could prove an efficient catalyst for performing this reaction. Called a nanonet because of its two-dimensional branching structure, the material is made up of a compound that has been demonstrated to enable the water-splitting reaction. Because of its high surface area, the nanonet enhances this reaction.
