Online — Nuts are considered a healthy snack, but whether they grow in the ground or on trees, there’s always the risk for contamination.

Following Salmonella outbreaks in 2001 and 2004, almonds are required to be pasteurized, which has other nut processors taking precautionary steps to ensure their product doesn’t lead to the next outbreak.

To maintain the taste and crunch we expect from our favorite nut, processors often turn to roasting, blanching or steam to reduce any potential contamination without the use of chemicals.

For dry roasting processes, nuts are continuously conveyed through a roaster with heated air applied above and below the product bed.

Typically, peanuts are exposed to temperatures of 300 °F for 25 minutes, then stored in stainless steel bins in an isolated area to protect them from any contaminants.

The bed depth, time and temperature are monitored throughout the roasting process. Continue reading

Optimised Air-cooled Condenser for Small Scale Reactions

Asynt CondenSyn MINI Waterless condenser

Asynt CondenSyn MINI Waterless condenser

Isleham, UK  —  Asynt have introduced the CondenSyn Mini – a new high performance air condenser optimised for small scale synthetic chemical reactions performed in 5, 10, and 25 ml flasks.

Just 20 cm long and fitted with a B14 adapter, theCondenSyn Miniprovides comparable vapour condensing performance to a Liebig water condenser but advantageously requires no cooling water for operation.

While condensers cooled by a circulating water are effective, their constant need for running tap water creates environmental and cost issues.

Proven in over 1000 installations worldwide the Asynt CondenSyn Miniair condenser is an affordable high-surface-area air condenser which is both safe and operationally effective.

The CondenSyn Mini’s robust design uses a new borosilicate glass manufacturing technique and this, together with a proprietary multiple hyperbolic profile, ensures optimum heat removal as vapours pass along its length. Continue reading

Shortwave infrared instrument from MIT for seeing into ears

Lets doctors see through eardrums to spot infections

Online — A new shortwave infrared (SWIR) device developed by researchers at MIT and a physician at Connecticut Children’s Medical Center could greatly improve doctors’ ability to accurately diagnose ear infections.

That could drastically reduce the estimated 2 million cases per year in the United States where such infections are incorrectly diagnosed and unnecessary antibiotics are prescribed.

Such over-prescriptions are considered a major cause of antibiotic resistance.

The new device, whose design is still being refined by the team, is expected ultimately to look and function very much like existing otoscopes, the devices most doctors currently use to peer inside the ear to look for signs of infection. Continue reading

Online — Three Australian research satellites – two of them built at the University of New South Wales – will be launched to the International Space Station this year and deployed into orbit to explore the little-understood region above Earth known as the thermosphere.

The trio is part of an international project known as QB50, which will see a total of 50 small satellites – known as cubesats and weighing just a kilo each – carry out the most extensive measurements ever undertaken of the region between 200 and 380 km above Earth. Continue reading

Physicists Reach 91 K with Laser Cooling

By CSA Editor

by Aaron Hilf, University of New Mexico

Online  —  A group of scientists in the University of New Mexico’s Department of Physics & Astronomy are using lasers to advance optical refrigeration, a technique that reaches cryogenic temperatures without any moving parts.

Led by Dr. Mansoor Sheik-Bahae, professor of physics and astronomy, the group is using laser light to chill a special type of crystal that can then be attached to devices requiring constant and reliable cooling, like infrared detectors on satellites.

“Right now, anything that cools other parts of a system has moving parts. Most of the time, there’s liquid running through it that adds vibrations which can impact the precision or resolution of the device,” explains Aram Gragossian, a research assistant in Sheik-Bahae’s lab.

“But, when you have optical refrigeration, you can go to low temperatures without any vibrations and without any moving parts, making it convenient for a lot of applications.”
