Materials management deals with the research, development, manufacturing and processing of raw and industrial materials. Key aspects here are biological and medical issues, which play an increasingly important role in this field.
innovations-report offers in-depth articles related to the development and application of materials and the structure and properties of new materials.
The same characteristics that make misfolded proteins known as prions such a pernicious medical threat in neurodegenerative diseases may offer a construction toolkit for manufacturing nanoscale electrical circuits, researchers report this week in the online edition of the Proceedings of the National Academy of Sciences.
Scientists working at Whitehead Institute for Biomedical Research and the University of Chicago write that they have used the durable, self-assembling fibers formed by prions as
Scientists and engineers trying to share materials property data over the Internet will have an easier time now thanks to a new computer language called MatML--Materials Markup Language--developed by an international group of researchers from the National Institute of Standards and Technology (NIST), industry, government laboratories, universities, standards organizations and professional societies. MatML provides a standard format for managing and exchanging materials property data on the World Wide
Nanocomposites for space
A microscopy technique originally developed to image the molecular-scale topography of surfaces is now helping engineers choose the right materials for a new generation of lightweight high-strength composites based on carbon nanotubes.
Light, conductive and nearly as strong as steel, carbon nanotubes are being combined with lightweight polymers to produce composite materials with properties attractive for use on future space vehicles. But choosing th
In recent years chemists and materials scientists have enthusiastically searched for ways to make materials with nanoscale pores -- channels comparable in size to organic molecules -- that could be used, among other things, to separate proteins by size. Recently Cornell University researchers developed a method to "self-assemble" such structures by using organic polymers to guide the formation of ceramic structures.
Now they have advanced another step by incorporating tiny magnetic particle
How do you improve on plastic, a modern material that has already changed the way we do everything from design medical devices to build cars? Embed it with specialized proteins called enzymes, says Shekhar Garde, assistant professor of chemical engineering at Rensselaer Polytechnic Institute.
"Such protein-enhanced plastics might someday be able to act as ultra-hygienic surfaces or sensors to detect the presence of various chemicals," says Garde. These types of materials could have a wide
Intriguing Structural Strategy Aims at Making Designer Plastics Affordable
The future was supposed to be "plastics," according to advice given in a 1960s movie The Graduate. Many a company thought that future meant the gradual ascendancy of "designer" or specialty plastics, but almost 40 years later the market is still dominated by plastics that can be manufactured cheaply in bulk.
Six researchers from the University of California at Santa Barbara (UCSB) and one at Helsinki U
Reinforced high-strength concrete can crack due to stresses that develop during the hardening process. However, this has been found to be surprisingly less quick than previously thought. Due to Dutch research, extra steps during the hardening process can be omitted. This will result in cheaper concrete.
Maya Sule from Delft University of Technology tested specimens of high strength concrete (concrete with little water) in a temperature stress testing machine (TSTM). Such tests indicate the
University of Minnesota researchers have made the first-ever hardness measurements on individual silicon nanospheres and shown that the nanospheres’ hardness falls between the conventional hardness of sapphire and diamond, which are among the hardest known materials. Being able to measure such nanoparticle properties may eventually help scientists design low-cost superhard materials from these nanoscale building blocks.
Up to four times harder than typical silicon-a principal ingredient o
Technical Insights materials and chemicals research service: Advanced materials technology
Advanced materials look set to revolutionize numerous applications in the 21st century. Scientists and engineers are undertaking extensive research activities in their quest to develop sophisticated new materials that are more durable, environmentally friendly, and energy efficient.
"Advanced materials and chemicals are the enabling building blocks for future devices and systems,
The development of a new generation of membranes based on conducting polymers has been the subject of a recent line of research in the Department of New Materials at CIDETEC, in association with the LEIA Technological Centre.
This involves a field of work wherein the excellent advantages presented by electro-dialysis conventional membranes (continuous separation, low energy consumption, ease of combination with other separation processes, absence of additives) are combined with other, highl

Computer simulation shows how the icy moon heats water in a porous rock core
Heat from the friction of rocks caused by tidal forces could be the “engine” for the hydrothermal activity on Saturn's moon Enceladus. This presupposes that...
The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
