Two newly developed, low-cost tests that use nanoparticles to detect chemicals can accurately measure tiny amounts of two potentially harmful herbicides in fruits, vegetables and their products.
The 1T polymorph of TaS2 is one of the prominent members of the quasi-2D van der Waals materials that reveal several charge-density-wave (CDW) phase transitions in the form of resistivity changes and hysteresis. However, despite numerous attempts, the electrical gating of the CDW phase, which is needed for many practical applications, has remained elusive - until now. Researchers report electrical gating of the CDW quantum phases in h-BN/1T-TaS2.
