By Jennifer WillsBuzzfeedA study finds barium ions can be detected in electronic signature PDFs.

It’s an interesting and novel result, but one that requires further research.

The new research paper, published in the journal ACS Applied Materials & Interfaces, is titled “An optical barium-based device for detection of electronic signatures.”

It’s written by researchers at the University of Waterloo and the University at Buffalo, and is funded by the U.S. Department of Energy.

The study’s co-authors are graduate student Daniel L. Doyon, associate professor of mechanical engineering, and graduate student Chris L. Paine, all of whom worked on the device.

The researchers’ main goal was to find a way to produce an electronic signature that was at least 10 times brighter than what the device can produce by itself.

The optical signature was generated by using a baradium atom as a light source and then using a low-pass filter.

They found that the barium atoms can be excited at temperatures that make the baradium ions glow red, and that the intensity of the glow depends on the temperature of the barradium atoms.

The research paper describes how the bar-based detector works.

The researchers placed the bar on a substrate with a temperature of 0.6 Kelvin, and a temperature that was higher than the temperature that would be needed to produce the bar.

Then they used a laser to beam a laser beam through the substrate.

The beam traveled through the bar, which emitted the energy from the laser beam.

When the beam left the bar the laser was stopped by the bar’s magnetic field.

The light energy is then sent back to the detector, where it is analyzed.

The authors found that, for each barium atom present, the intensity can be up to 50 percent brighter than the signal that was emitted by the optical sensor.

The bar-less optical device, which is similar to an electronic fingerprint, can be created by using an electron as a source of energy.

The electron can be generated by the addition of an electron beam to a standard silicon or aluminum oxide crystal.

The silicon or an aluminum oxide is placed on a magnetic dipole and placed on top of a magnetic coil.

When a light wave passes through the crystal, it is picked up by the coil, and the light is reflected off the surface of the coil and emitted back to a detector.

The device is not the only way barium could be used as an electronic device.

In 2011, scientists at the Institute of Quantum Materials at University of Zurich in Switzerland reported that they had created a device that emits a laser pulse and then picks up light emitted by a bar of barium on a silicon substrate.

The next step is to find an efficient way to convert barium into a non-radioactive form.

The barium that has been used as a barometer for many years is not suitable for use in this way, as the bar is not an element and therefore it does not emit light.

The next step would be to convert the bar into a bar-free form, which could be more economically.

Barium is an extremely stable element, so converting it into a pure form would require significant amounts of energy and a lot of material.
