These would react with barium ions in the test, giving an incorrect positive result. Explain why, in a test for halide ions, the sample is acidified with dilute nitric acid first. Carbonate ions ...

According to the group, chemical coordination between 4PTSC and SnI2 shields the perovskite surface, and passivates uncoordinated Sn2+ and halide ions, suppressing deep trap state formation.

Metal halide perovskites (MHPs) have become a powerful candidate for new LEDs due to their excellent photoelectric properties. By doping metal ions into MHPs, fluorescent materials with different ...

Originally the property most conveniently measured was the chlorinity, or halide ion (mainly Cl-and Br-) concentration. Chlorinity was measured using a straightforward chemical titration ...

Sodium Chloride is an alkali halide with an fcc crystal structure. The basis is two ions, a sodium cation and a chlorine anion. The crystal lattice parameter is 0.563 nm. The diagram shows both a unit ...

These compartments are isolated from each other but remain connected through silver/silver-halide redox electrodes, enabling ...

A team including researchers from Seoul National University College of Engineering has developed neuromorphic hardware ...

Lithium-ion (Li-ion) battery technology has historically been the power cell of choice, especially given that we’re always all looking to maximize our smartphone’s battery life. However ...

Seoul National University College of Engineering has announced that a research team led by Professor Ho Won Jang from the ...

Screen sizes and camera quality continue to improve in smartphones each year. Halide offers a professional camera experience with control over exposure and focus. Process Zero in Halide creates ...
