A team of material scientists led by Prof. Qi Li from Southwest Jiaotong University in Chengdu, China recently outlined the state of inducing piezoelectricity in distorted rutile TiO 2 for enhanced ...

The effect: polarisation and electric field are pointing in the same direction. With positive d33, the sample expands, whereas the material is contracting when d33 is negative. Since 2011, it has been ...

Researchers have developed a novel type of nanomechanical resonator that combines two important features: high mechanical quality and piezoelectricity. This development could open doors to new ...

Earthquakes may cause gold nuggets to form in quartz by generating an electric field that attracts gold dissolved in fluid forced up from deep underground. Enormous gold nuggets are often associated ...

We can't usually feel them, but dozens of earthquakes occur every day—and some of them are using mundane minerals to make glittering gold. Researchers have found that tectonic shifts put just the ...

Gold nuggets have long fascinated treasure hunters and geologists alike, often found gleaming within quartz veins deep underground. Yet the exact process behind the formation of these ...

The accuracy of a generated frequency depends upon the reference element selected. The purpose of this note is to provide a background on the crystal reference element and its impact in an oscillator ...

When strained by earthquakes, underground networks of quartz veins can generate enough voltage to snatch gold from passing fluids, researchers report September 2 in Nature Geoscience. The findings ...
