The same antifreeze proteins that keep organisms from freezing in cold environments also can prevent ice from melting at warmer temperatures, according to a new Ohio Univ. and Queen's Univ. study.

Johns Hopkins researchers have discovered that, under the right conditions, nanocrystalline materials—like those found in some integrated circuits—exhibit surprising activity in the tiny spaces between the geometric clusters of atoms called nanocrystals, from which they are made. This has implications for those who use thin films or manufacture MEMS.

A team of Northwestern Univ. researchers has discovered that X-rays can trigger the formation of a new type of crystal: charged cylindrical filaments ordered like a bundle of pencils experiencing repulsive forces, which is unknown in crystals.

Adding fluorine during the growth of certain types of crystals which are popular with makes of optical devices, microelectronics and superconductors helps transfer highly-ordered structures. But hydrogen fluoride then builds up, slowing or stopping growth. Brookhaven Lab scientists have found a way remove that gas, uniformly and by absorption.

A pulse propogating through a string of atoms can be visualized using a new mathematical technique developed at NIST that uses a Green’s function. It’s an important advance in understanding natural phenomenon such as vibrations propagating through crystals because even today’s supercomputers cannot handle the billions of time steps required to model the interactions of thousands of atoms.

An Ames Laboratory metallurgist is watching transparent
crystals grow aboard the International Space Station in the hopes that the low gravity
will erase the effects of convection, or the natural circulation of fluid.
Removing this effect should simplify the process of matching experimental data
on crystal growth to theoretical models done on the computer.

New York Univ. chemists have created three-dimensional DNA structures, a breakthrough bridging the molecular world to the world where we live. The work also has a range of potential industrial and pharmaceutical applications, such as the creation of nanoelectronic components and the organization of drug receptor targets to enable illumination of their 3D structures.

Researchers for the first time observed magnetic monopoles and how they emerge in a real material. Magnetic monopoles are hypothetical particles proposed by physicists that carry a single magnetic pole, either a magnetic North pole or South pole. In the material world this is quite exceptional because magnetic particles are usually observed as dipoles, north and south combined.

New UBC research has literally and figuratively poked holes in single-band Hubbard physics—a model that has been used to predict and calculate the behavior of high-temperature superconductors for 20 years. The findings are the first compelling evidence challenging the model under certain conditions, and could necessitate entirely new theoretical approaches to explaining superconductivity in cuprate materials, one of the outstanding mysteries in condensed-matter physics.

The boundary where liquid and crystal meet is known as the intrinsic interface, but until now only theories existed as to how the crystal particles and the liquid particles remained separate. Images published this week show the narrow fuzzy region between the two states, an area that fluctuates due to surface waves.
