Mercury-Vapor Lamp

Many photochemical processes rely on UV light from inefficient or toxic light sources that the LED technology cannot replace for technical reasons. An international team of scientists led by Professor Christoph Kerzig of Johannes Gutenberg University Mainz (JGU) in Germany and Professor Nobuhiro Yanai of Kyushu University in Japan has now developed the first molecular system for the conversion of blue light into…

Time isn't the same for everyone, even on Earth. Flying around the world gave Einstein the ultimate test. No one is immune from relativity.

As an engineering plastic having high transparency and impact resistance, polycarbonate (PC) is employed in eyeglass lenses, camera lenses, DVDs, automobile headlights and bulletproof glass.

Devices using shorter UV light could keep indoor air free of viruses without harming human health

[This is a transcript of the video embedded below. Some of the explanations may not make sense without the animations in the video.] Forget war, forget climate change, recessions, pandemics. Today we'll talk about a real crisis. The decrease of testosterone levels. Just look at all those headlines. There must be something going on. But what? Are testosterone levels really falling? If so, why? And how much of a…

The same math that describes supernovas makes EUV lithography possible

Integrated optical signal distributing, processing, and sensing networks require the miniaturization of basic optical elements, such as waveguides, splitters, gratings, and optical switches. To achieve this, fabrication approaches that allow for high-resolution manufacturing are required.

To sit under the vast expanse of stars is to imagine swimming across shining, stellar rivers, creeks and tributaries. But to sit here also is to feel that lump in your throat and skip in your heart, realizing everything you know is far smaller than the majesty of the universe.

From Rubylith to EUV

A new publication in Opto-Electronic Science reports how high-quality diamonds empower narrowband deep ultraviolet photodetection.

Mercury Arc Rectifiers covert alternating current (AC) to direct current (DC) using mercury vapour. See two working examples at Kempton.

The invention and evolution of the modern light bulb have changed the way we view and interact with our environment. Starting with Thomas Edison's groundbreaking innovation of 1879, to the advancement of modern LED lamps.

Here's why energy saving light bulbs have become so popular and how they light up our homes, schools and workplaces.

Field-effect transistors (FETs) are transistors in which the resistance of most of the electrical current can be controlled by a transverse electric field. Over the past decade or so, these devices have proved to be very valuable solutions for controlling the flow of current in semiconductors.
