Environmental Impacts and Cost Analysis of Perovskite Nanocrystals for Light‐Emitting Diode Applications

open access: yesAdvanced Sustainable Systems, EarlyView.
CsPbBr₃ colloidal nanocrystals synthesized via hot‐injection (HI) and microwave‐assisted (MW) methods exhibit excellent optoelectronic properties for LEDs. Although the MW route is more energy‐efficient and eco‐friendly in the lab, industrially, its environmental impacts are similar, but with lower costs.

Uranus: Microwave Images

Science, 1984
Observations of Uranus at wavelengths of 2 and 6 centimeters with the Very Large Array were made in 1980 and 1981. The resulting maps of brightness temperature show a subsolar symmetry at 2 centimeters but a near-polar symmetry at 6 centimeters. The 6-centimeter maps show an increase in temperature from equator to pole with some evidence for a warm ...

A microwave imager

Measurement Techniques, 2000
Designs and basic characteristics are considered for imagers having ellipsoidal-mirror and lens antennas. These operate in the 8 mm range and are intended for ultrasensitive measurement of millimeter-range field patterns and for the construction of images by computer processing.

Microwave imaging sensors

2020
Microwave imaging (MWI) systems are nowadays acquiring an ever-growing importance in numerous application fields, such as non-destructive testing (NDT) in civil and industrial applications, subsurface sensing and ground penetrating radar (GPR) prospection, through-wall imaging (TWI) for security and biomedical imaging.

Breast Phantoms for Microwave Imaging

IEEE Antennas and Wireless Propagation Letters, 2014
Herein, we study the dielectric properties of various mixtures susceptible to be used in manufacturing of reference inhomogeneous breast phantoms dedicated to the experimental validation of microwave breast imaging systems in the 0.5-6-GHz frequency range.

Imaging Techniques for Microwave Diagnostics

Contributions to Plasma Physics, 2011
AbstractImaging diagnostics, such as Electron Cyclotron Emission Imaging (ECEI) and Microwave Imaging Reflectometry (MIR), exhibit unique characteristics that make them particularly well suited to the validation of theoretical models for plasma instabilities and turbulent fluctuations.
