Brewed coffee has a small bite that can bring it down to the desired temperature, but sometimes it gets cold quickly, especially when something else distracts you in the morning. California-based Ember Technologies has developed a coffee cup that claims to keep your drink at the right temperature for a long time, and users can set the temperature through the appropriate smartphone app or turn the bottom of the cup.

The Ember mug holds 12 ounces (350ml) and uses patented hot and cold phase change technology to keep the coffee or tea in the cup at an ideal temperature for about 2 hours. Phase change materials change from one state to another at different temperatures. For example, in a hot environment, it changes from a solid to a liquid, absorbing and storing heat in the process. When it is cold, it returns to the solid state and releases heat.

There are many possibilities for this material. Researchers explore its applications in buildings, robots, new refrigerators and mugs. After some efforts, German scientists developed a phase-change mug in 2009, saying that the ideal temperature for coffee could be maintained for 30 minutes, while in 2013, researchers developed a mug that could last "for hours."
