Proveedora Industrial Minera Andina S.A. (PIMASA) began its operations in 1969 to sell ferroalloys and calcium carbide in the local market. Since then, PIMASA has widen its business areas and multiply its line of products, thus covering important requirements from Mining, Metallurgical, Mechanics, C more
AN INDUSTRIAL COMPLEX FOR METAL TRANSFORMATION Located near the seaport zone of Lima, the capital of Peru, Industrias Electro Químicas (IEQSA) is the largest industrial complex dedicated to zinc transformation in Peru, and all of South America. Its operations include the production of metallurgica more
It is not easy to make batteries cheap, efficient, durable, safe and environmentally friendly at the same time. Researchers at ETH Zurich have now succeeded in uniting all of these characteristics in zinc metal batteries. The world needs cheap and powerful batteries that can store sustainably produc more
By analysing meteorites, Imperial researchers have uncovered the likely far-flung origin of Earth’s volatile chemicals, some of which form the building blocks of life. They found that around half the Earth’s inventory of the volatile element zinc came from asteroids originating in the outer Solar S more
A team of researchers at Empa developed a water-activated disposable paper battery. The researchers suggest that it could be used to power a wide range of low-power, single-use disposable electronics – such as smart labels for tracking objects, environmental sensors and medical diagnostic devices – more
This graphic looks at the colour of various metal and metalloid ions that occur during flame tests. Most people probably remember doing this experiment in school chemistry lessons, if not with the full range of ions shown here, but for the uninitiated a brief explanation of the origin of the colours more
A previous post looked at the colours of transition metals, and the origin of their colours – this graphic, on the other hand, looks at how transition metals (and some non-transition metals) can be identified by the precipitates they form with sodium hydroxide and ammonia solutions. I’m going to kee more
Here’s the start of a new series of collaborations with MEL Science, looking at a number of fun chemistry experiments and the explanations behind them. Today’s initial offering looks at how zinc pellets can be transformed into tin hedgehogs with some simple chemistry. more
