Discovery Unlocks ‘hot’ Electrons for Efficient Energy use

Researchers developed a technique that uses a scanning tunneling microscope integrated with lasers and other optical components to trap appropriate molecules and measure the energy distribution of hot electrons in a thin gold film. (Illustration by Enrique Sahagún)

Highly energetic, “hot” electrons have the potential to help solar panels more efficiently harvest light energy. But scientists haven’t been able to measure the energies of those electrons, limiting their use. Researchers at Purdue University and the University of Michigan built a way to analyze those ene

PSDcast – Cooking the World's Fastest Pizza

Kanthal, which specializes in industrial heating technology, designed an oven that uses electromagnetic radiation to cook a whole pizza in 37 seconds, a world record.

One of the topics we cover on a regular basis is “thermal management,” and normally that means waste heat or cooling off electromechanical systems, but if we take it to the consumer side, it could refer to this neat story that crossed my desk about the world’s fastest pizza. Kanthal  Be sure to catch us on i

Low EMI, Silent Switcher, 1.2 A µModule Regulator in 4 mm × 4 mm × 1.82 mm BGA Package

Click image to enlarge

Figure 1. The LTM8074 uses Silent Switcher architecture for a complete low noise solution in a tiny package.

Crowded application boards leave little space for high performance DC-to-DC POL converters. Furthermore, electromagnetic interference (EMI) is a significant concern at high component densities, limiting the field of acceptable power solutions. The LTM8074 µModule regulator easily meets these limiting factors. It

Automotive Exterior Lighting Solutions

Figure 1. Power Consumption Characteristics Comparison

Changing exterior lamps from bulbs to LEDs makes it possible to achieve smaller, thinner light sources, allowing more manufacturers to improve lamp design. To improve design, it is necessary to increase LED output while reducing the power consumption of the LED drive control circuit along with size. At the same ti
