UBC chemists create a new model to predict the optical properties of non-conducting ultra-fine particles, which could inform the design of nano-structures and help study cosmic dust formation. The findings have potential applications in remote sensing and drug delivery systems.
Researchers at NC State University create core/shell nanoparticles with gold and silver, as well as alloy nanoparticles, using the 'digestive ripening' technique. This method allows for control over optical properties of the resulting nanoparticles.
Researchers develop scalable devices exhibiting customizable optical properties using a bottom-up approach inspired by nature. The findings showcase potential applications in sensitive sensors, detectors, and invisibility cloaks, and demonstrate the possibility of manipulating artificial molecules to create desired optical properties.
Scientists at NIST made precise measurements of nanotube concentrations for transparent conducting sheets, revealing the importance of uniform length for high-performance films. The study validated one theory, showing that longer nanotubes become electrically conducting at lower concentrations.
Researchers at Arizona State University have made a breakthrough in understanding the effect of brown carbon on climate change by developing a novel technique to measure its optical properties. This discovery could lead to more accurate forecasting of global warming activity, as current models often overlook this key component.
University of Oregon chemist Jim Hutchison has developed a method to rapidly generate diverse libraries of functionalized gold particles with cores of 11 gold atoms. The new synthesis technique offers great promise for research and development at the nanoscale.
Hydrogel nanoparticles provide a foundation for creating self-assembled periodic structures that can transmit specific wavelengths of light. By controlling the de-swelling process, the researchers can tune the colors to one-nanometer steps over a wavelength range of more than 200 nanometers.
Researchers at Northwestern University have developed a method to create triangular nanoprisms in large quantities, which can be used as new diagnostic labels for detecting biological weapons and diseases. The nanoparticles' unique optical properties make them a promising building block for detection science.
A five-year ONR-sponsored initiative aims to investigate optical properties of the shallow ocean floor to enhance remote sensing and underwater imaging capabilities. The experiment will aid in mine detection and provide high-resolution maps of coral reef ecosystems, enabling easier disease spotting.
