Nanotube 'Sponge' Has Potential In Oil Spill Cleanup
2012-05-10 12:51:25

A carbon nanotube sponge that can soak up oil in water with unparalleled efficiency has been developed with help from computational simulations performed at the Department of Energy's (DOE's) Oak Ridge National Laboratory. Carbon nanotubes, which consist of atom-thick sheets of carbon rolled into cylinders, have captured scientific attention in recent decades because of their high strength, potential high conductivity and light weight. But producing nanotubes in bulk for specialized...

Traditional silicon-based integrated circuits are found in many applications, from large data servers to cars to cell phones. Their widespread integration is due in part to the semiconductor industry´s ability to continue to deliver reliable and scalable performance for decades. However, while silicon-based circuits continue to shrink in size in the relentless pursuit of Moore´s Law – the prediction that the number of transistors that can fit on an integrated circuit...

Chemical sensors are exceedingly good at detecting a single substance or a class of chemicals, even at highly rarified concentrations. Biological noses, however, are vastly more versatile and capable of discriminating subtle cues that would confound their engineered counterparts. Unfortunately, even highly trained noses do leave a certain ambiguity when relaying a signal and are not particularly suited for work in specialized situations like operating rooms. A new DNA-based chemical sensor...

New Sensor Detects When Fruits And Vegetables Are Spoiling
2012-05-01 04:43:15

Lee Rannals for RedOrbit.com A new sensor may one day be able to help U.S. supermarkets prevent the loss of produce due to spoilage. According to the Department of Agriculture (USDA), supermarkets in America lose about 10 percent of their fruits and vegetables every year to spoilage. MIT chemistry professor Timothy Swager and his students have built a new sensor that could help grocery stores get more efficient at combating the loss. Plants discharge ethylene, a gas that helps...

Rice, Tsinghua collaboration could yield low-cost, efficient alternative to silicon-based cells Forests of carbon nanotubes are an efficient alternative for platinum electrodes in dye-sensitized solar cells (DSC), according to new research by collaborators at Rice University and Tsinghua University. The single-wall nanotube arrays, grown in a process invented at Rice, are both much more electroactive and potentially cheaper than platinum, a common catalyst in DSCs, said Jun Lou, a...

Researchers at Rice University and Penn State University have discovered that adding a dash of boron to carbon while creating nanotubes turns them into solid, spongy, reusable blocks that have an astounding ability to absorb oil spilled in water. That´s one of a range of potential innovations for the material created in a single step. The team found for the first time that boron puts kinks and elbows into the nanotubes as they grow and promotes the formation of covalent bonds, which...

Clark School Researchers Discover Nanoscale Phenomenon, Potential Computer Speed Advantages COLLEGE PARK, Md., April 9, 2012 /PRNewswire-USNewswire/ -- Scientists have discovered that when electric current is run through carbon nanotubes, objects nearby heat up while the nanotubes themselves stay cool, like a toaster that burns bread without getting hot. Understanding this phenomenon could lead to new ways of building computer processors that can run at higher speeds without...

A dose of carbon nanotubes more than doubles the growth rate of plant cell cultures – workhorses in the production of everything from lifesaving medications to sweeteners to dyes and perfumes – researchers are reporting. Their study, the first to show that carbon nanotubes boost plant cell division and growth, appears in the journal ACS Nano. Mariya V. Khodakovskaya and colleagues explain that their previous research demonstrated that so-called multiwalled carbon nanotubes...
