Intermediate-mass Black Holes in Dwarf Galaxies

, 2019
Supermassive black holes are the central engines of active galactic nuclei (AGN) and are thought to lie at the heart of many massive galaxies. It is currently uncertain, however, whether AGN exist in low-mass dwarf galaxies, and if they do, whether they are powered by intermediate-mass black holes (IMBHs)- a missing population of black holes with ...

Seedless One‐Pot Synthesis of Colloidal InAs Quantum Dots Enabling a High‐Accuracy Photoplethysmography Oximeter

Advanced Science, EarlyView.
A real‐time, non‐contact photoplethysmography (PPG) system based on InAs colloidal quantum dots (CQDs) synthesized via a seedless injection synthesis is demonstrated. The measured oxygen saturation shows considerable agreement with commercial PPG devices.

Surface‐Interaction‐Driven Polarity Switching in II–V Cd3P2 Colloidal Quantum Dots for Infrared Photodiodes

Advanced Science, EarlyView.
. ABSTRACT Colloidal quantum dots (CQDs) based on II–V semiconductors offer attractive optical absorption and carrier transport properties for infrared optoelectronics, yet their device‐relevant electronic behavior remains poorly understood. In particular, Cd3P2 CQDs have been constrained by limited control over nanocrystal growth and carrier polarity.
