Two-color glowing molecule could make wind tunnel tests more accurate

Most sensors can measure only one thing at a time, like a thermometer for temperature or a pressure gauge for pressure. Measuring two properties accurately from the same surface at the same moment usually means using two separate instruments—adding cost and complexity to the process.

Plasma treatment helps reveal how molecular coatings dope silicon

Controlling dopant concentration near the silicon surface is increasingly important for ultrashallow junctions and nanoscale devices. Mixed monolayer doping (MMLD) offers a surface-chemistry-based approach in which dopant-containing molecules are mixed with nondopant molecules to tune the amount of dopant available at the silicon surface…
