TL;DR: This work highlights that GQDs can act as a superfast electron tunnel for optoelectronic devices and improve perovskite solar cells' power conversion efficiency.

TL;DR: In this paper, defect emissions exhibited a strong dependence on the temperature and excitation wavelength, with some defect emissions observable only at low temperatures and for certain excitation wavelengths, while green emission was not significantly affected by annealing.

TL;DR: In this paper, the toxicity of metal oxide nanomaterials and their antimicrobial activity is attracting increasing attention among these materials, MgO is particularly interesting as a low cost, environmentally-friendly material.

TL;DR: A class of near infrared- absorbing organic molecules with intramolecular motion-induced photothermy inside nanoparticles, which enables most absorbed light energy to dissipate as heat, makes the nanoparticles a superior photoacoustic imaging agent compared to widely used methylene blue and semiconducting polymer nanoparticles and allow them for high-contrast photoac acoustic imaging of tumours in live mice.

TL;DR: In this paper, the degree of substitution (DS) was determined by a colorimetric method using the Raman and Fourier transform infrared spectra of the native and modified polysaccharides of cellulose, guar gum, locust bean gum and xanthan gum.
