High-quality microwave signals generated from tiny photonic chip

In a new Nature study, Columbia Engineering researchers have built a photonic chip that is able to produce high-quality, ultra-low-noise microwave signals using only a single laser. The compact deviceā€”a chip so small, it ...

Ant pheromones may help protect hikers and campers from ticks

If you're outside enjoying the spring sunshine, then chances are, ticks are too. However, new research from Simon Fraser University (SFU) suggests the use of ant pheromones as a topical repellent, or as an environmental barrier, ...

3D microelectrode chip helps soil nutrient analysis

Researchers have developed a novel microfluidic chip with capacitively coupled contactless conductivity detection (C4D) integrated 3D microelectrodes to rapidly and quantitatively determine abundant nutrient ions in soil.
