A new concept of more environmentally friendly aircraft
NASA funds an aeronautical research project on a new fuel concept.
HACCP food safety plans must be improved
HACCP has the top non-conformity figures globally across certified sites, according to a British Retail Consortium (BRC) report.
Natural refrigerants power the transition to climate-friendly transport refrigeration
Refrigerated transport is essential to global food and pharmaceutical supply chains – but it’s also a hidden source of greenhouse gas emissions. As climate targets tighten and refrigerants face regulatory...
UK: 50% of refrigeration plant end-users might not comply with F-Gas requirements
Many equipment owners believe that because they have a maintenance contract with an F-gas registered service company, they are fully covered in terms of F-gas compliance.
Noise reduction strategies for screw compressors
The operating noise of twin-screw compressors is an important issue that may limit their scope of application. Two recent IJR papers suggest several noise reduction methods and analyse their...
Radiative cooling coatings that can adapt to the seasons
A novel material can be used as a coating on building’s rooftops or windows to provide radiative cooling in the summer without overcooling in the colder months.
Spacewalkers replace the cooling pumps of the ISS cosmic particle detector
Two astronauts just finished successfully repairing the cooling pumps of the Alpha Magnetic Spectrometer fitted to the International Space Station.
HFC phase-down: update on the Kigali Amendment and the EU F-gas Regulation
In the European Union, the F-gas Regulation’s objectives were broadly respected in 2017; at an international level, the Kigali Amendment came into force on January 1, 2019, with currently 67 ratifying states.
Ozone-depleting chemicals detected by scientists in the atmosphere in 1951 – decades earlier than expected
An international team led by the University of Bremen, Germany, has uncovered evidence of ozone-depleting chlorofluorocarbons (CFCs) in the atmosphere as early as 1951. This finding pushes back the known...
Out of the ordinary: tasting robot
A state-of-the-art tasting robot may transform quality and safety checks. Papero, a 60-com robot developed by NEC, is fitted with infrared spectroscopic technology and a processor and software. It can identify foods, list their ingredients and...
Unreported HFC-23 emissions
A report published in Geophysical Research Letters says that Western Europe's emissions of HFC-23 are around twice as high as the officially reported level within the framework of the Kyoto Protocol.
New radiative cooling technology promises breakthrough for vertical surfaces
A new radiative cooling material designed for vertical surfaces demonstrates cooling 2.5°C below ambient, offering solutions for urban heat.
Passive radiative cooling: promising results for a polymer film
A new material using radiative cooling was tested by a team of researcher at Boulder, Colorado. The results show that is could become a viable solution for supplemental cooling for buildings.
Producing ammonia using less energy
Scientists at the Tokyo Institute of Technology have developed an improved catalyst facilitating the synthesis of ammonia at merely 50°C (when conventional techniques require temperatures of 450°C).
Cryogenic testing on the successor of Hubble Telescope
NASA engineers completed final cryogenic testing on James Webb Space Telescope a few months ago.
