TL;DR: In this paper, the authors developed an efficient approach for preparation of ultrafine and well-dispersed crystalline Fe-doped TiO2 nanoparticles (Fe-TiO2) with a size distribution of 2.3 ± 0.9 nm under mild conditions by using covalent organic frameworks (COFs) as the interface engineering agent.

TL;DR: In this article, a vertical (Cl)-GQDs based photovoltaic detectors have been demonstrated, both the light absorbing and electron accepting roles for (Cl) GQDs in photodetection have been found, resulting in an exceptionally big ratio of photocurrent to dark current as high as ∼105 at room temperature using a 405nm laser irradiation under the reverse bias voltage.

TL;DR: A sensor array with 4 units to detect 4 VOCs, showing good selectivity, that could be used for the real-time monitoring of indoor air quality and will be useful in situations requiring the simultaneous detection of multiple V OCs.

TL;DR: In this article, the reduced graphene oxide-wrapped hollow SnO2 nanospheres (H-SnO2@rGO) composites are successfully synthesized via a simple hydrothermal method without any templates added.

TL;DR: In this paper, a chlorine doped GQD (Cl-GQD) based photovoltaic photodetectors have been fabricated using a solution process, and it was found that the presence of GQDs can significantly enhance the performance of the device.
