Some scientists have been exploring sugar alcohols as a possible material for making thermal storage work, but this direction has some limitations. One group of researchers wanted to investigate how mixing carbon nanotubes with sugar alcohols might affect their energy storage properties.
A new prototype of a lithium-sulphur battery - which could have five times the energy density of a typical lithium-ion battery - overcomes one of the key hurdles preventing their commercial development by mimicking the structure of the cells which allow us to absorb nutrients.
In order to understand how the brain controls functions, such as simple reflexes or learning and memory, we must be able to record the activity of large networks and groups of neurons. Conventional methods have allowed scientists to record the activity of neurons for minutes, but a new technology, known as a bionic hybrid neuro chip, is able to record activity in animal brain cells for weeks at a much higher resolution.
In two papers, published this week, scientists determined a more precise version of a basic law of physics - which says that disorder tends to increase with time unless acted on by an outside force - and applied it to the smallest quantum systems.
Engineers have manufactured tiny, star-shaped structures out of interconnected beams, or trusses. The structures, each about the size of a sugar cube, quickly shrink when heated to about 282 degrees C.
