Japanese scientists produce artificial palladium

Japanese researchers have used nanotechnology to develop a process which resembles something out of a 16th Century alchemy textbook. Although not producing gold, as was the aim of the alchemists, the scientists have discovered a technique that allows otherwise inert elements to be combined to form new intermediate alloy-elements. So far, an alloy of palladium has been created by mixing silver and rhodium together.
Professor Hiroshi Kitagawa and his team used nanotechnology to combine rhodium and silver to produce an alloy with similar properties to palladium, which is located between rhodium and silver on the periodic table. These two metals usually would not mix, as rhodium has 45 electrons and silver 47, and so are stable elements unable to react with each other under normal conditions. The research team overcame this hurdle by mixing rhodium and silver in solution which was then turned into a mist and mixed with heated alcohol. This process produced particles of the new alloy that are around 10 nanometres in diameter.

Liquid foam makes for smarter greenhouses

While greenhouses allow certain crops to be grown throughout the year, excess temperature, solar radiation and high vapor pressure deficit can cause problems during the summer months. With conventional solutions, such as shade screens, often being labor intensive and reducing the quality of light within the growing space, Canadian company Sunarc has a developed a new liquid foam shading system that mimics cloud cover to automatically shade greenhouses. As the liquid foam filters the sunlight, it reduces solar radiation and controls temperature, but doesn’t deprive the plants of vital light spectra they require for photosynthesis.
Shade panels are made from two layers of polyethylene film between which the foam is pumped as required – the more foam deposited the more shade produced. A sensor system, which monitors the microclimate within the growing space, regulates the foam and sprinklers as conditions demand. Software is programmable to local needs and may be monitored and operated by remote computer control.

The perfect box for all shapes

This one-size-fits-all packaging concept delivers an efficient way to send an item by reducing bulk and cost while keeping your goods safe from bumps and scrapes in transit. The clever Universal Packaging System (UPACKS) system – not be confused with UPS (United Parcel Service) – from designer Patrick Sung uses perforated sheets made from recyclable corrugated cardboard that can snugly pack almost any shaped item, whilst reducing the need to pad-out empty spaces.
