MRS Selects Outstanding 2004 Fall Meeting Symposium Papers
Trophy Awards (Best paper) and Ribbon Awards (Best nomination) were given to select papers from the 2004 MRS Fall Meeting as selected by the symposium organizers.
The very first MRS Bulletin theme topic was "Advances in Ion Beam Processing and Synthesis" published in the February/March, 1987 issue. The Guest Editor of the issue was C.W. (Woody) White.

Schematic phase diagram for microemulsions with two-phase (orange, yellow, red) and three-phase (dark blue, light blue) regions. For similar concentrations of oil, water, and amphiphile, a lamellar phase occurs as a result of organizing principles that are argued to be more general than the specifics of these materials suggest at first glance.The competition between local incompatibilities of states and phases and global constraints (charge and concentration balances) leads to emergent behavior in complex materials of very different kinds.

Metallic glass performs better under stress
By the addition of an appropriate amount of aluminum to a copper-based alloy, a group has now produced the first amorphous material that gets harder under stress. A different group has developed a cerium-based metallic glass material that can be molded in hot water--at less than 100 degrees .
New law allows for unlimited optical resolution in fluorescence microscopy
Researchers have succeeded in overcoming the law postulated by Ernst Abbe in 1873 for diffraction-limited resolution in light microscopes. They have established a new law that allows for unlimited resolution in fluorescence microscopy.
Solving the hopping problem in semiconducting polymers
A unified theoretical description of the charge-carrier mobility in disordered semiconducting polymers has been established, which is in excellent agreement with experimental measurements. At room temperature, mobility was found to be mainly determined by the carrier density, but at low temperatures and high electric fields, the field dependence became important.
Single-crystal-like PZT formed
Researchers report a new, easy method for the formation of "single-crystal-like" PZT. The material bridges the gap between real single crystals and the typical randomly oriented ceramics. The properties of this new material approach those of true single crystal PZT.
Carbon nanotubes made from grass
A new method for making multiwalled carbon nanotubes by heating grass in the presence of oxygen has been demonstrated. The nanotubes were about 1 micron long and 30 to 50 nm in diameter.
Nanoprinter could mass-produce nano-devices
A new printing method, called Supramolecular Nano-Stamping (SuNS), has been developed wherein single strands of DNA essentially self-assemble upon a surface to duplicate a nano-scale pattern made of their complementary DNA strands. This increases print output exponentially while enabling the reproduction of very complex nano-scale patterns.
Database of "Biological patents" created
Technologists are increasingly borrowing ideas from nature. A database of “biological patents” has now been created that will allow for searching through a wide range of biological mechanisms and properties to find natural solutions to technological problems.
Researchers strike gold in cancer detection
A unique method of detecting cancer has been developed using gold nanoparticles. The gold nanoparticles that were bound to a specific antibody displayed a 600 per cent greater affinity for cancer cells than for noncancerous cells.
Layered nanotubes composed almost entirely of DNA created
The first layered nanotubes composed almost entirely of DNA have been created. The layers of the DNA in the nanotubes are held together by hybridization of a series of DNA strands which fall apart when heated, releasing single-stranded DNA. |

COMPLEX ADAPTIVE MATTER: EMERGENT PHENOMENA IN MATERIALS
June 2005 Issue
Guest Editors: Daniel L. Cox and David Pines
How can an assembly of molecules (us) actually know just what a molecule is? This classic scientific question illustrates the concept of "emergent phenomena": incidents that owe their existence to interactions between many subunits, but  whose existence cannot be deduced from a detailed knowledge of each subunit alone. Materials exhibiting emergent behavior are called "complex adaptive matter," and their relevant organizing principles are unique to their scales of length and time. In this issue of "MRS Bulletin", articles are centered on the organizing principles of such materials as the authors concentrate on the character of emergence for particular systems and the role of materials science in developing approaches to their study. The theme provides an overview of research on complex adaptive matter through a survey of five examples, ranging from intrinsically disordered electron matter in high-temperature superconductors to protein aggregates in amyloid diseases like Alzheimer’s.

:: Of Interest to the MRS Community
Professor Morris Cohen (1912-2005)
Morris Cohen, a world-renowned metallurgist and an MIT institute professor who received both the National Medal of Science and the Kyoto Prize for Advanced Technology, died May 27. He was 93. Cohen made significant contributions to the understanding of the structure of matter, and the ways in which materials can be processed. His work has been central to the development of modern high-strength steels.

Optical micrograph of a solid-state refrigerator based on normal metal–insulator–superconductor
(NIS) junctions composed of Al and Al-Mn
electrodes. The refrigerator has limited
cooling capacity, but is suitable for critical
applications in which a primary refrigerator
or liquid cryogen cools a device to subkelvin
temperatures, and the solid-state
refrigerator provides a secondary cooling
source to pull a device below a critical temperature.

New Transilluminator Has Both White and Blue LED Light Sources
The Spectroline® BlueGlo™ transilluminator uses non-UV light sources to illuminate fluorescently stained DNA, RNA, proteins and other biological samples without the risk of photonicking or additional generated heat.
The transilluminator’s blue light excites fluorophores between 450nm and 500nm, with a peak at 470nm. It’s ideal for illuminating SYBR® dyes, fluorescein/FITC, GFP, EtBr, chemifluorescence, and a wide range of visible dyes and autorad film. A small footprint makes it perfect for laboratories where space is at a premium.
