The solid-state integration of molecular electron spin qubits could promote the advancement of molecular quantum information science. With highly ordered structures and rational designability, microporous framework materials offer ideal matrices to host qubits. They exhibit tunable phonon dispersion relations and spin distributions, enabling optimization of essential qubit properties including the spin-lattice relaxation time (T) and decoherence time.

Although a plethora of evidence suggests a positive relationship between exercise and lower levels of depression in youths, the findings regarding the variation in magnitude of this relationship are inconclusive with respect to the preventive and therapeutic effects of different types of exercise. This network meta-analysis aimed to determine the best type of exercise for the treatment and prevention of depression in youths.

Herein, our sound strategy for enhancing the selectivity is to saturate the under-coordinated single Pt atoms with Cl ligands. In this system, the weak electronic metal-support interactions between Pt atoms and reduced TiO cause electron extraction from Pt to Cl ligands, resulting in strong Pt-Cl bonds.
