A general approach for all-visible-light switching of diarylethenes through triplet sensitization using semiconducting nanocrystals
A simple, efficient and general approach for all-visible-light switching of photochromic diarylethenes is developed through triplet sensitization from CdS nanocrystals, which has high potential for all-visible-light activated optoelectronics.

Antibonding induced anharmonicity leading to ultralow lattice thermal conductivity and extraordinary thermoelectric performance in CsK2X (X = Sb, Bi)
A first principles-based machine learning potential is developed to model the phonon transport properties in full Heusler CsK2Sb and CsK2Bi taking account of all higher-order phonon interactions.

Phase separation in alkali silicate glasses detected through inverse Laplace transform of 29Si nuclear magnetic resonance echo train decay
The ratio of Si-29 nuclear magnetic resonance coherence lifetimes for Q4 and Q3 sites under magic-angle spinning and a π-pulse train in silicate glasses can detect phase separation, even at small scales where the glass appears optically homogenous.

Up-conversion charging of a Tb3+-activated garnet phosphor
An up-conversion charging process in a Gd3Ga5O12:Tb3+ persistent phosphor is achieved upon illumination by a 488 nm laser. An energy-transfer mechanism dominates the up-conversion excitation.

Aligned chromophores in a host–guest MOF crystal for switchable polarized nonlinear optical response
By preparing a host–guest MOF to elaborately arrange donor–acceptor ligand and dye guests, second-harmonic generation and two-photon-pumped lasing can be switched in a MOF crystal by orthogonally manipulating the excitation polarization direction.
