A team of researchers led by Assistant Professor Yuki Arakawa (Toyohashi University of Technology, Japan) has successfully developed sulfur-containing liquid crystal (LC) dimer molecules) with ...

Helical gearboxes and gearheads are mechanical devices used to transmit torque between shafts. They feature angled gear teeth that engage gradually, allowing for smooth and efficient power ...

The choice between helical and spur gears in gearboxes may seem straightforward. Go with helical gears if you want the gearbox to run as smoothly and quietly as possible. Choose spur gears when you ...

Researchers have developed a flexible fiber sensor with a double-helical structure that places both electrodes on one end. This design improves durability, allowing the sensor to endure repeated ...

A trend gaining ground at industrial plants over the past decade has manufacturers replacing traditional spur and worm gears with high-efficiency helical gears. While sometimes viewed as a pricey ...

Science has long taken inspiration from the natural world, and few natural designs are as iconic as the helical shape that makes life possible. The best-known example of such a molecule is DNA, a ...

Building antennas is a time-honored ham radio tradition. Shortwave antennas tend to be bulky but at VHF frequencies the antenna sizes are pretty manageable. [Fjkaan’s] 2 meter quadrifilar helicoidal ...
