CultureLab-UK News
The November edition of Culture Lab is now live. Log on now to our Bond special, featuring two fascinating articles: 1. Die Another Day - Despite fierce competition from Hollywood rivals, the new Bond film remains 'The Daddy' of hi-tech film production. 2. Bond UK - Want to know what unbelievable technology is just around the corner? Watch a Bond... view more... (2002-11-14)

Breaking harmful bonds
Everybody loves the way breakfast eggs conveniently slide off of Teflon without leaving any pesky pieces of egg in the pan. Indeed, the carbon-fluorine bond at the heart of Teflon cookware is so helpful we also use it in clothing, lubricants, refrigerants, anesthetics, semiconductors, and even blood substitutes.   view more (2008-08-29)

Durability of dental fillings improves if the enzyme activity of teeth is inhibited
Composite dental fillings have one problematic feature, in that the bond between the filling and the dental tissue deteriorates over time - in fact, sometimes by as much as 50 per cent in one year. As the bond deteriorates, it may allow bacteria to enter and this brings a high risk of further tooth decay.   view more (2009-02-12)

Sticky gel could have held the London Eye
These so-called "Trib-gels", being developed by Tribtech, are smeared onto the surfaces of the two components to be joined together. Moving the two components relative to eachother causes a metal-to-metal bond that resembles the 'galling' of two metals, dramatically increasing the frictional properties of the materials. This bond would have held... view more... (1999-10-29)

Unlike rubber bands, molecular bonds may not break faster when pulled
From balloons to rubber bands, things always break faster when stretched.   view more (2009-06-18)

Beyond the bonds that bind: UCSB researchers discover hydrogen can form multicenter bonds
Researchers at the University of California, Santa Barbara have shown that, under the right circumstances, hydrogen can form multicenter bonds, where one hydrogen atom simultaneously bonds to as many as four or six other atoms.   view more (2006-12-04)

Fingerprint analysis technique could be used to identify bombmakers
University of Leicester experts have held discussions with military personnel in Afghanistan following the discovery of new technology to identify fingerprints on metal.   view more (2008-08-27)

Pitt, NETL researchers report molecular chain reaction thought to be impossible
People said it couldn't be done, but researchers from the University of Pittsburgh and the U.S. Department of Energy National Energy Technology Laboratory (NETL) in Pittsburgh demonstrated a molecular chain reaction on a metal surface, a nanoscale process with sizable potential in areas from nanotechnology to developing information storage... view more...

Raman Effect Brings Nano up to Size : Raman/Rayleigh Imaging of Nanosized Materials
Materials made with (or from) nanophases received considerable attention in the last few years but their characterisation is not easy. Unique properties (conductivity, diffusion, reactivity, sintering, mechanical strength….) have been reported for nanostructured materials, all of which result from the interfacial characteristics. Raman... view more... (2003-06-08)

Dads behind bars
Dads behind bars see prison as a chance to think about the needs of their children and an opportunity to re-bond with them.   view more (2005-03-18)

Good vibrations: Aging bones may benefit from a good shaking
While running and jumping are some of the best ways to maintain or improve bone strength and help prevent fractures, they aren't the safest activities for the frail, elderly or physically impaired.   view more (2007-02-20)

Surprisingly, Chemists Find, Some Solvents Can Alter Chemical Bonds
New University at Buffalo research demonstrates that some solvents can significantly enhance certain acid-base interactions and strengthen the bonding interaction between two molecules when one is electron-deficient and one is electron-rich.   view more (2007-07-25)

Nanotechnology may increase longevity of dental fillings
Tooth-colored fillings may be more attractive than silver ones, but the bonds between the white filling and the tooth quickly age and degrade.   view more (2009-07-02)

A single water molecule acting as gate keeper
How do the bonds cells form with their environments rupture? What enables some cells to migrate? It is known since quite a while that cells can have complex mechanical interactions with their environments. Not only the biochemical but also the physical properties of their environment can thus have significant impact on cell behavior and even gene... view more... (2004-11-12)

A molecular switch turns on the flame in 'nature's blowtorch'
Uncontrolled reaction of organic compounds with oxygen is easy: we call it fire. But nature often needs to do oxidations very specifically, adding oxygen to a particular carbon atom in a complicated molecule without disturbing anything else.   view more (2008-05-30)

Study suggests preseason shoulder strength may determine injury severity for baseball pitchers
Athletic injuries can derail any player's ability to compete, but for a baseball pitcher his shoulder strength and control is critical.   view more (2009-07-10)

New 'litmus test' could aid discovery of anti-cancer drugs
Using the unusual color properties of gold at the nanoscale, scientists at Northwestern University have developed a "litmus test" for DNA and small molecule binding that eventually could be used by pharmaceutical companies to rapidly identify promising candidates for new anti-cancer drugs.   view more (2006-03-29)

Silicon nitride - Improving the properties of one of the world's most important structural materials
With excellent high temperature strength, good resistance to oxidation and low coefficient of thermal expansion Si3N4 ceramic is one of the most important structural materials. However, the pure silicon nitride ceramics are difficult to densify and the addition of various oxides is used to improve sinterability.   view more (2005-10-27)

New imaging technique reveals how likely you are to break a bone
Scientists have developed a technique which can be used to reveal the strength of bones, allowing doctors to more accurately estimate the risk of bone fracture.   view more (2005-10-26)

U of M researchers discover key for converting waste to electricity
Researchers at the University of Minnesota studying bacteria capable of generating electricity have discovered that riboflavin (commonly known as vitamin B-2) is responsible for much of the energy produced by these organisms.   view more (2008-03-04)
