  • Improving the capacitive deionisation performance by optimising pore structures of the electrodes

    In this paper, three types of ordered mesoporous carbons (OMCs) were synthesised by an original template method and a modified sol-gel process involving nickel salts. The effects of pore arrangement pattern (ordered and random), and pore size distribution (mesoporous and microporous) on the desalination performance were investigated by comparing mesoporous carbons with activated carbons (ACs). It ...

  • How can I measure the pH of food?

    Measuring pH in food is a useful indicator of consistency over batches for quality control but can also be used to monitor foods where the pH changes over time – for example in yogurt production, brewing or to test the freshness of foods. Standard pH electrodes will often struggle when used in food samples, as the reference junction becomes blocked the reaction time will get slower and ...

  • Chlorine Dioxide gas detection: A comprehensive guide

    Introduction Some years agoago, the bleaching process in the paper industry was changed from using Chlorine (Cl2) as bleaching agent to Chlorine dioxide (ClO2). This was a challenge forThis posed a major challenge to industrial hygienists, as there were no sensors or detectors available that were specific to Chlorine dioxide: There was no sensor technology for gas detectors available that ...

  • Buy Smarter – what questions should you ask when buying a pH meter?

    When you’re looking to buy a pH meter, whether it’s to start measuring or to replace an existing meter, the range of brands and specifications available is huge. With so many options it can be difficult to know where to start, but taking a little time to choose carefully could save you a lot of time and money overall by making sure the meter you choose is right for ...

  • Proposal of a framework for scale‐up life cycle inventory: A case of nanofibers for lithium iron phosphate cathode applications

    Environmental assessments are crucial for the management of the environmental impacts of a product in a rapidly developing world. The design phase creates opportunities acting on the environmental issues of products using life cycle assessment (LCA). However, it is hampered by a lack of information originating from distinct scales along the product or technology value chain. There are many ...
