#These LEGO-inspired ceramics won t shatter California Institute of technology rightoriginal Studyposted by Brian Bell-Caltech on September 12 2014scientists are on the way to developing the perfect ceramic material:

In a paper published in the journal Science the researchers explain how they used the method to produce a ceramic (e g. a piece of chalk

After the patterning step they coated the polymer scaffold with a ceramic called alumina (i e. aluminum oxide) producing hollow-tube alumina structures with walls ranging in thickness from 5 to 60 nanometers and tubes from 450 to 1380 nanometers in diameter.

That was not surprising given that ceramics especially those that are porous are brittle. However compressing lattices with a lower ratio of wall thickness to tube diameter#where the wall thickness was only 10 nanometers#produced a very different result. ou deform it

and they could still recover. o understand why consider that most brittle materials such as ceramics silicon

#Ceramic converter tackles solar cell problem Stanford university rightoriginal Studyposted by Mark Shwartz-Stanford on October 21 2013coating a solar cell component in ceramics makes it more heat resistant

When subjected to temperatures of 1800 F (1000 C) the ceramic-coated emitters retained their structural integrity for more than 12 hours.

The ceramic-coated emitters were sent to Fan and his colleagues at Stanford who confirmed that devices were still capable of producing infrared light waves that are ideal for running solar cells. hese results are unprecedentedsays former Illinois graduate student Kevin Arpin the lead author of the study. e demonstrated for the first time that ceramics

could help advance thermophotovoltaics as well other areas of research including energy harvesting from waste heat high-temperature catalysis

is established well. opefully these results will motivate the thermophotovoltaics community to take another look at ceramics

Then they uniformly coated that polymer lattice with thin layers of the ceramic material titanium nitride (Tin)

and then process it in such a way that it s made out of almost any material class we d likeâ##for example metals ceramics

In the Nature Materials work the team tested the individual octahedral cells of the final ceramic lattice

Typical ceramics fail because of flawsâ##the imperfections such as holes and voids that they contain. e believe the greater strength of these nanostructured materials comes from the fact that

#Ceramics surprise with durable dryness Coatings that repel water are found in myriad applications#they keep car windscreens clear in storms, for example,

following the discovery that a well-known family of durable ceramics can repel water. That is surprising because most ceramics are hydrophilic.

When water meets a ceramic such as aluminium oxide the water s oxygen atoms share some of their electrons with vacant electron orbitals on the aluminium atoms,

and the oxygens in the ceramic share their electrons with hydrogen in the water. This binds the two together.

But what if a ceramic failed to accept electrons from water? Then the ceramic might actually be reasoned hydrophobic

Kripa Varanasi, a materials scientist at the Massachusetts institute of technology (MIT) in Cambridge. He looked to the oxides of the lanthanides#the row of metals nestled almost at the bottom of the periodic table, from cerium to lutetium.

Cheung suggests that Varanasi's ceramics were particularly hydrophobic because they had very few oxygen defects-perhaps a consequence of their formation in dry air at high temperatures of around 1,

500#C. Varanasi says that hydrophobic ceramics could improve the efficiency of energy generation. As steam passes through the turbines of a thermal power station

A hydrophobic coating made of tough ceramic would prevent films of water forming on the blades,

#Novel solar photovoltaic cells achieve record efficiency using nanoscale structures Here's how to make a powerful solar cell from indium and phosphorus:

In conventional, oxygen-conducting SOFCS, the membrane is made from a ceramic called yttria-stabilized zirconia,

In recent years, researchers have begun exploring alternative membranes made from ceramics called yttrium-doped barium zirconates (BZY.

Mixing the different ceramic components typically requires heating them to temperatures as high as 1700°C But at that extreme temperature,

which makes it harder to mix it uniformly throughout the ceramic. Oayre and his colleagues have helped recently pioneer an alternative mixing scheme called solid state reactive sintering,

the Caltech researchers explain how they used the method to produce a ceramic (e g.,, a piece of chalk or a brick) that contains about 99.9 percent air yet is incredibly strong

"Ceramics have always been thought to be heavy and brittle, "says Greer, a professor of materials science and mechanics in the Division of Engineering and Applied science at Caltech."

they coated the polymer scaffold with a ceramic called alumina (i e.,aluminum oxide), producing hollow-tube alumina structures with walls ranging in thickness from 5 to 60 nanometers and tubes from 450 to 1, 380 nanometers in diameter.

That was not surprising given that ceramics especially those that are porous, are brittle. However, compressing lattices with a lower ratio of wall thickness to tube diameterhere the wall thickness was only 10 nanometersroduced a very different result."

"To understand why, consider that most brittle materials such as ceramics, silicon, and glass shatter because they are filled with flawsmperfections such as small voids and inclusions.

N y. For nearly three decades Krishan Luthra stubbornly labored away in a General electric research lab on a long-shot effort to cook up a new type of ceramic that few consumers will ever see or use.

The material is a type of ceramic that is hard and can handle high heat, like the ceramics people have been making for 25,000 years.

But this ceramic is a complex composite that is also very light, and tough like a metal.

No one wants the aircraft engine that is holding them 35,000 feet above the earth to shatter like a vase.

But coating these fibers with a ceramic each just one eighth the width of a human hair, evenly, was extremely difficult. f you don do that right you get a ceramic that behaves like china,

and if you do it right you get ceramic with metal properties, and that the big deal, he says.

He figured how to apply the coatings to each individual fiber in something called a chemical vapor deposition reactor,

#Researchers develop harder ceramic for armor windows The Department of defense needs materials for armor windows that provide essential protection for both personnel

With the highest reported hardness for spinel NRL's nanocrystalline spinel demonstrates that the hardness of transparent ceramics can be increased simply by reducing the grain size to 28 nanometers.

Sintering is a common method used to create large ceramic and metal components from powders.

and reposition nanoparticles very close to each other to help eliminate porosity in the sintered ceramic. NRL researchers then can exploit the increased surface potential of nanoparticles for surface energy-driven densification without coarsening.

when you make a ceramic material nanocrystalline. However in their work the NRL researchers have shown that the fracture resistance does not change suggesting that nanocrystalline ceramics can have an equivalent toughness to microcrystalline ceramics

which is important for high window lifetimes. The Hall-Petch relationship has been used to describe the phenomenon where a material's strength

However prior experimental work had shown a breakdown in this relationship (where hardness starts reducing with decreasing grain size) for certain ceramics at 130 nanometers.

and the Teflon has a low refractive index. When combined, they create a metamaterial, capable of bending light in unusual ways.

and joints they could make ceramics metals and other materials that can recover after being crushed like a sponge.

Ceramics for example are strong but also heavy so they can t be used as structural materials where weight is critical##for example in the bodies of cars.

And when ceramics fail they tend to fail catastrophically shattering like glass. But at the nanoscale the same rules do not apply.

In this size range the structural and mechanical properties of ceramics become less tied to properties such as weight

For ceramics smaller is tougher says Greer who was named one of MIT Technology Review s 35 Innovators Under 35 in 2008 for her work on nanoscale mechanics.

Greer worked with the company to characterize the material and later chose to take on the greater challenge of making ceramics with similar properties.

The polymer lattice is coated then with a ceramic such as alumina. Oxygen plasma etches out the polymer leaving behind a lattice of hollow ceramic tubes.

When the walls are thick the ceramic shatters under pressure as expected. But trusses with thinner walls just 10 nanometers thick buckle

The new materials might be particularly interesting for use in batteries notes Nicholas Fang a mechanical engineer at MIT who is also working on nanostructured ceramics.
