Online  —  The thermal conductivity of molten plastics is an important material property from the point of view of plastics processing since it affects temperature distribution and cooling behavior of the melt.

Accurate thermal conductivity characterization of the polymer feedstock supports increased productivity and better quality of finished product.

It is vital for reliable process simulation of extrusion and injection moulding processes. Continue reading

Estimating changes in global temperature since the pre-industrial period

Bulletin of the American Meteorological Society: Abstract of Early Release Paper

Screen Shot AMS LogoOnline  —  Better defining (or altogether avoiding) the term ‘pre-industrial’ would aid interpretation of internationally agreed global temperature limits and estimation of the required constraints to avoid reaching those limits.

The United Nations Framework Convention on Climate Change (UNFCCC) process agreed in Paris to limit global surface temperature rise to ‘well below 2 °C above pre-industrial levels’. But what period is ‘pre-industrial’? Continue reading

New miniaturized two-channel infrared detectors

Enhance product series at InfraTec

Miniaturized two-channel detector LRM-102

LRM-102

Dresden/ GERMANY — After launching the LRM?254 just a few months ago, InfraTec has expanded its range of miniaturized multi-channel detectors.

With the LRM-102 and LRM-202 a pair of two-channel detectors with an aperture opening of around 6 mm2 are now following in the TO46 housing. Just like the premiere model of the series, these latest developments are also characterised by their innovative design.

The IR filter is directly above the pyroelectric element in the centre of the detectors. This saves important space when assembling and improves the protection of the filters against external influences tremendously. Continue reading

NIST Physicists Squeeze Light, Cool Microscopic Drum Below Quantum Limit

By CSA Editor

Online — Physicists at the National Institute of Standards and Technology (NIST) have cooled a microscopic mechanical drum to less than one-fifth of a single quantum, or packet of energy.

The result, according to the research team, is lower than ordinarily predicted by quantum physics and the technique used could theoretically cool objects to absolute zero, the temperature at which matter is devoid of nearly all energy. Continue reading
