Multifunctional scalable coated paper sheets for UV shielding and sublimation printing applications
Microwave treatment mechanism
The interaction was based on the scientific theory that microwave radiation has high selectivity, and this selectivity depends on the dipole moment of the materials exposed to it. Furthermore, numerous investigations…

Non-monotonic size-dependent exciton radiative lifetime in CsPbBr3 nanocrystals
We investigated the effect of nanocrystal size on optical properties, focusing on the radiative lifetime. Over 30 high-quality nanocrystals samples were synthesized following a modified version of previous reports (details in the Method section)…

Quantum electrometer for time-resolved material science at the atomic lattice scale
Monte Carlo simulations
Here, we provide an overview of the general methodology of simulating single and multimodal spectra (Fig. 2b). The simulations begin with distributing charge traps uniformly within a specified volume or surface. For…

Enhancing fresh-cut spinach preservation with carbon quantum dot-based composite coatings
Characterization of the SCCD composite coating
CDs’ morphology was observed by TEM imaging. The generated CDs seemed monodispersed and had a spherical shape, as observed in Fig. 1B. As shown in Fig. 1A, the size distribution of the CDs has…
