  • Sending messages using household chemicals

    Nearing the completion of his master’s degree in computer engineering and computer science at York University in Ontario, Canada, Nariman Farsad was considering pursuing further study elsewhere. But his supervisor, Andrew Eckford, convinced him to stay by suggesting an odd line of research. The idea more

  • A battery made of wood?

    A sliver of wood coated with tin could make a tiny, long-lasting, efficient and environmentally friendly battery. But don’t try it at home yet – the components in the battery tested by scientists at the University of Maryland are a thousand times thinner than a piece of paper. Using sodium instead o more

  • European Commission approves BASF’s acquisition of Cognis

    The European Commission approved the acquisition of Cognis Holding GmbH by BASF SE. The approval is subject to the divestiture of businesses that accounted for sales of significantly less than €100 million, which is less than 3% of Cognis’ total sales. In addition, the Chinese authorities approved t more

  • Bearing grease selection

    Rolling-element bearings are used for the precise guidance of moving parts. Frictional losses are extremely small because the bearings rest on rolling elements, enabling very heavy loads to be adsorbed. Rolling-element bearings may be lubricated with more

  • Application of the Amplifluor® SNPs Genotyping System using a FLUOstar OPTIMA microplate reader

    The detection of SNPs (single nucleotide polymorphisms) is an important tool for researchers in order to find mutations in DNA sequences. In this application note we describe a homogeneous fluorescence assay based on PCR. The Amplifluor® S more

  • The Secret of Bearing Lubrication

    At the heart of almost every industrial facility are electric motors, which can render equipment inoperative should their rolling element bearings fail-an occurrence more common than necessary due to strain resulting from improper lubrication more

Acids, Alkalis, and the pH Scale

The pH scale is something we’re all familiar with; most people will remember it from school chemistry lessons. It’s the scale used to rank how strong an acid (or alkali) a solution is. The colours associated with each number correspond to the colour that universal indicator turns in solutions of tha more

The Colours & Chemistry of pH Indicators

Most of us, chemists or otherwise, have probably come across pH indicators at one point or another. I’d be surprised if there’s anyone out there who hasn’t, back in school, carried out the standard experiment of adding universal indicator to a variety of household liquids to identify them as acidic more
