Scientists Discover New Family Of Quasicrystals
2013-06-10 15:38:35

Ames Laboratory Scientists at the U.S. Department of Energy´s (DOE) Ames Laboratory have discovered a new family of rare-earth quasicrystals using an algorithm they developed to help pinpoint them. Quasicrystalline materials may be found close to crystalline phases that contain similar atomic motifs, called crystalline approximants. And just like fishing experts know that casting a line in the right habitat hooks the big catch, the scientists used their knowledge to hone in on just...

Research Shows Possibilities For Quasicrystals

Syracuse University Ever since their discovery in 1984, the burgeoning area of research looking at quasiperiodic structures has revealed astonishing opportunities in a number of areas of fundamental and applied research, including applications in lasing and sensing. Quasiperiodic structures, or quasicrystals, because of their unique ordering of atoms and a lack of periodicity, possess remarkable crystallographic, physical and optical properties not present in regular crystals. In the...

In Search Of Natural Quasicrystals

April Flowers for redOrbit.com - Your Universe Online An expedition to far eastern Russia, a 15,000 year old meteorite, secret diaries, smugglers, gold prospectors and bears; sounds like the plot to an Indiana Jones movie, right? This is the story of two researchers looking for the origin of naturally occurring quasicrystals. Who knew science could be so exciting? Writing in Reports on Progress in Physics, Paul J. Steinhardt and Luca Bindi reveal that new, naturally occurring...

According to a new study, crystals found in Russia's Koryak mountains two years ago may have come from space. Quasicrystals had only been created in the lab before geologists found them in rocks in Russia.  These crystals are unusual and were first described in the 1980s by Israeli research Daniel Shechtman. Quasicrystals break rules of symmetry that apply to conventional crystalline structures, and they also exhibit different physical and electrical properties. Luca Bindi from...

NEW YORK and HAIFA, ISRAEL, Oct. 5, 2011 /PRNewswire-USNewswire/ -- Distinguished Professor Dan Shechtman of the Technion-Israel Institute of Technology has won the Nobel Prize in chemistry, it was announced today. The Technion is now home to three of the four Israelis in the country's history to be awarded the Nobel Prize in science. Prof. Shechtman, of the Technion Faculty of Materials Engineering, won the award for his discovery of quasicrystals - an entirely new form of matter. The...

Nobel Chemistry Prize Awarded To Daniel Shechtman
2011-10-05 09:29:10

The Nobel prize for chemistry was awarded to an Israeli scientist whose work was once ridiculed for being out of line with received thinking. Daniel Shechtman, from the Israel Institute of Technology (Technion), won the entire $1.5 million 2011 Nobel prize for chemistry on Wednesday for discovering different ways in which atoms could be packed together in solid materials. His work has opened the door for experiments in the use of quasicrystals. The Royal Swedish Academy of Sciences said...

Novel nanostructure pattern never seen in a plastic material Professor Frank S. Bates and his research team at the University of Minnesota in Minneapolis have discovered an unusual type of soft material that was conceived of over 50 years ago, but has never before been found in a plastic--although it has been seen in stainless steel and other metal alloys. Bates' group, which is funded by the National Science Foundation's Division of Materials Research, specializes in creating a particular...

Two Kent State University professors are part of a team of researchers who recently uncovered a way to pack tetrahedra, considered to be the simplest shaped regular solids with its four triangular sides, more densely than ever before. Peter Palffy-Muhoray, professor of chemical physics and associate director of the Liquid Crystal Institute at Kent State, and Xiaoyu Zheng, assistant professor in Kent State's Department of Mathematical Sciences, along with four colleagues at the University of...

In a study that elevates the role of entropy in creating order, research led by the University of Michigan shows that certain pyramid shapes can spontaneously organize into complex quasicrystals. A quasicrystal is a solid whose components exhibit long-range order, but without a single pattern or a unit cell that repeats. A paper on the findings appears in the Dec. 10 issue of Nature. Researchers from Case Western Reserve University and Kent State University collaborated on the study. Entropy...

The method to the madness of quasicrystals has been a mystery to scientists. Quasicrystals are solids whose atoms aren't arranged in a repeating pattern, as they are in ordinary crystals. Yet they form intricate patterns that are technologically useful.A computer simulation performed by University of Michigan scientists has given new insights into how this unique class of solids forms. Quasicrystals incorporate clusters of atoms as they are, without rearranging them as regular crystals do,...
