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...

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...

Researchers from Stanford University and the U.S. Department of Energy's SLAC National Accelerator Laboratory have created the first-ever system of "designer electrons" — exotic variants of ordinary electrons with tunable properties that may ultimately lead to new types of materials and devices. "The behavior of electrons in materials is at the heart of essentially all of today's technologies," said Hari Manoharan, associate professor of physics at Stanford and a member of SLAC's...

Nanotube Tech Leading To Faster, Lower-cost Medical Diagnostics
2012-03-11 07:11:06

Researchers at Oregon State University have tapped into the extraordinary power of carbon “nanotubes” to increase the speed of biological sensors, a technology that might one day allow a doctor to routinely perform lab tests in minutes, speeding diagnosis and treatment while reducing costs. The new findings have almost tripled the speed of prototype nano-biosensors, and should find applications not only in medicine but in toxicology, environmental monitoring, new drug...

Seoul, Feb 27, 2012 - (ACN Newswire) - Hanyang University of Korea and RIKEN of Japan, in cooperation with other Asian universities and research institutes, are launching the Asian Research Network (ARN) which aims to strengthen research and educational cooperation across Asia. Recently ARN members succeeded in producing transparent touch sensors using carbon nanotubes and ink solutions that can print electronic circuits or change colour in exposure to heat or UV radiation.The spirit of...

Researchers at the NanoScience Center of the University of Jyväskylä, Finland, and at Harvard University, US, have discovered a novel way to make nanomaterials. Using computer simulations, the researchers have been able to predict that long and narrow graphene nanoribbons can be rolled into carbon nanotubes by means of twisting. The research has received funding from the Academy of Finland. The basic idea is simple and easily explained: just twist the ends of...

Discovery is designed to allow inexpensive detection of poisonous industrial gases by workers wearing small sensor chips filled with gold nanowires Researchers at the University of Pittsburgh have coaxed gold into nanowires as a way of creating an inexpensive material for detecting poisonous gases found in natural gas. Along with colleagues at the National Energy Technology Laboratory (NETL), Alexander Star, associate professor of chemistry in Pitt's Kenneth P. Dietrich School of Arts and...


Word of the Day
omphalos
  • The navel or umbilicus.
  • In Greek archaeology: A central boss, as on a shield, a bowl, etc.
  • A sacred stone in the temple of Apollo at Delphi, believed by the Greeks to mark the 'navel' or exact center-point of the earth.
'Omphalos' comes from the ancient Greek.
