Platinum works beautifully. It speeds up chemical reactions, holds up under punishment, and sits reliably at the center of industrial processes worth billions of dollars annually. It also costs ...

The linearity of triangular waveforms makes the triangular-wave generator useful in sweep circuits and test equipment. For example, switched-mode power supplies and induction motor-control circuits ...

A research team at King’s College London has isolated a triangular aluminum compound, called a cyclotrialumane, that can split hydrogen and react with ethene, behaviors normally reserved for expensive ...
