New Insight Into Aluminium
Aluminium is a metal widely used in industry; therefore the more that is known about it, the more effectively it can be used. Researchers at Ris'¸ National Laboratory in Denmark and the European Synchrotron Radiation Facility (ESRF) in France have filmed in 3D the changes in the bulk of deformed aluminium after annealing. Thanks to the uniqueness... view more... (2004-07-09)
NIST team develops novel method for nanostructured polymer thin films
All researchers at the National Institute of Standards and Technology (NIST) wanted was a simple, quick method for making thin films of block copolymers or BCPs (chemically distinct polymers linked together) in order to have decent samples for taking measurements important to the microelectronics industry. view more (2007-09-17)
Smaller is Stronger - Now Scientists Know Why
As structures made of metal get smaller - as their dimensions approach the micrometer scale (millionths of a meter) or less - they get stronger. Scientists discovered this phenomenon 50 years ago while measuring the strength of tin "whiskers" a few micrometers in diameter and a few millimeters in length. view more (2008-01-03)
Unusually stable glasses may benefit drugs, coatings
Just spray and chill. That sums up a new approach to making remarkably stable glassy materials from organic (carbon-containing) molecules that could lead to novel coatings and to improvements in drug delivery. view more (2006-12-11)
Dual enzymatic activity of RECQ1 explained by different quaternary structures
The transient opening of the DNA double helix is a fundamental step in several DNA metabolic processes. This reaction is driven by proteins called helicases, which make use of ATP as fuel to unwind the DNA duplex. view more (2007-01-16)
Polarization holographic device using photoreactive polymer liquid crystals
Photo-control of molecular orientation of polymer materials is of great interest for the development of highly functionalized holographic optical devices. view more (2005-10-19)
New mechanical heart implanted at the MUHC
Surgeons at the MUHC have successfully implanted a new kind of mechanical heart in two patients, the first time this new technology has been used in Canada. view more (2005-11-01)
A QUIET DRILL
The household and industrial heaters as well as glass and metal annealing furnaces are made of ordinary ceramics stand temperature difference poorly - the furnaces would crack as an common facetted glass where fiercely boiling water was pored in. That is why the annealing furnaces have to be heated and cooled gradually and insensibly. It takes... view more... (2003-04-25)
Harrowing bowel preparation is unnecessary before colorectal surgery
Research news from The Cochrane Library Surgeons and other experts have long regarded mechanical bowel preparation to be an essential preventative measure before colorectal surgery. Recent evidence in The Cochrane Library, however, reveals that mechanical bowel cleansing does not significantly decrease the risk of anastomotic leakage or other... view more... (2003-10-20)
Bridging the gap - mechanical support could increase survival of children requiring heart transplantation (pp 1948, 1967)
Embargoed 0001 h (London time) 12 December 2003. Fewer children should die while waiting for a heart transplant if they are given mechanical heart support before transplantation, conclude authors of a UK study in this week's issue of THE LANCET. Short-term mechanical heart support has potential for aiding children requiring heart transplantation.... view more... (2003-12-10)
Study supports the use of mechanical assistance for acute or chronic heart failure in high-risk patients
The success of long-term implantable ventricular assist devices (LVAD) or artificial hearts has led to their increased use in patients previously thought to be unsuitable for mechanical support. This study documents the shift in the demographic profile of patients in need of artificial hearts to a more high-risk group. Looking at clinical records... view more... (2004-11-10)
Lithium additions to nickel aluminides increases material strength
Intermetallics such as nickel aluminides have been of particular interest due to their excellent high temperature properties such as strength and corrosion resistance. view more (2007-06-14)
A CAR THAT RUNS ON FRESH AIR - ALMOST!
Karl's car finished 38th in a field of 109 entrants - an impressive feat by any standards. 'I built the car over a year as an A level technology project,' says Karl. 'The project was sponsored by Marine Projects at Lee Mill in Plymouth and the team consisted of myself and a friend, Sam Starmore, who drove the car for me.' view more (1999-02-01)
The fight for the best quantum bit (qubit)
Our results give us, for the first time, the possibility to understand the interaction between just two electrons placed next to each other in a carbon nanotube. view more (2008-06-25)
Cheaper and simpler keyhole surgery
Endoscopic surgery brings many advantages for patients but is very difficult for the surgeon. view more (2006-03-22)
Nanowire generates power by harvesting energy from the environment
As the sizes of sensor networks and mobile devices shrink toward the microscale, and even nanoscale, there is a growing need for suitable power sources. Because even the tiniest battery is too big to be used in nanoscale devices, scientists are exploring nanosize systems that can salvage energy from the environment. view more (2007-09-28)
New stretchable electrodes created to study stresses on cardiac cells
Engineers at Purdue and Stanford universities have created stretchable electrodes to study how cardiac muscle cells, neurons and other cells react to mechanical stresses from heart attacks, traumatic brain injuries and other diseases. view more (2009-01-23)
A new wrinkle in thin film science
A remarkably simple experiment devised by scientists yields important information about the mechanical properties of thin films--nanoscopically thin layers of material that are deposited onto a metal, ceramic or semiconductor base. view more (2007-08-08)
Mechanical thinning increases fruit size, reduces labor
Hand thinning is a necessary but costly management practice in peach and organic apple production. Mechanical devices designed to help with thinning have been developed, but none has proven highly effective and capable of completely replacing hand thinning. view more (2009-02-18)
The cost of long tongues
Orchid bees use their extraordinarily long tongues to drink nectar from the deep, tropical flowers only they can access. view more (2007-04-17)
