Abstract Carbon dots (CDs) were paid more and more attention for detecting ferric ions (Fe3+) containing in the organism or environment. Thus, nitrogen and phosphorus co‐doping green CDs were synthesized using p‐Phenylenediamine as the carbon sou

The strong coupling between electromagnetic field and lattice oscillation in piezoelectric materials gives rise to phonon polariton excitations. Such quasiparticles open up new directions in modulating the ubiquitous Casimir force. Here by utilizing

We derive an analytical expression for $s$-state exciton energies in monolayer transition-metal dichalcogenides (TMDCs): $E_{\text{ns}}=-{\text{Ry}}^*\times P_n/{(n-1/2+0.479\, r^*_0/\kappa)^2}$, $n=1,2,...$, where $r^*_0$ and $\kappa$ are the dimens

A new scheme for the computation of dispersive interactions from first principles is presented. This cost-effective approach relies on a Wannier function representation compatible with density function theory descriptions. This is an electronic-based

The effect of the ZnO addition to the pure perovskite PZT-PMnN-PSbN ceramics sintered at 950–1200 °C was investigated. The phase structure of ceramics changes from rhombohedral to tetragonal, and the sintering temperature decreases with the increa
