Making Photoresponsive Metal–Organic Frameworks an Effective Class of Heterogeneous Photocatalyst
This review summarizes photoresponsive MOFs for photocatalytic applications, focusing on their capacity to enhance light harvesting, charge transfer, and surface reactions. While existing studies provide foundational insights, emerging characterization techniques enable a deeper understanding of photoresponsive MOFs.

Scalable Quantum Computing with "Enhancement" Quantum Dots [PDF]
We propose a novel scheme of solid state realization of a quantum computer based on single spin "enhancement mode" quantum dots as building blocks. In the enhancement quantum dots, just one electron can be brought into initially empty dot, in contrast to depletion mode dots based on expelling of electrons from multi-electron dots by gates.

A scintillating polymeric composites loaded with hafnia nanoparticles is engineered to obtain a highly luminous material, thus achieving a 400% improvement of the scintillation yield under soft X‐rays. The nanocomposite is employed to realize a multilayer heterostructured prototype scintillator than enable for ultrafast time coincidence resolution in ...

Carboxyl‐functionalized graphene quantum dots (cGQDs) exhibit high singlet oxygen quantum yield due to strong spin–orbit coupling. cGQDs achieve minimum bactericidal concentration of only 0.4 µg mL−1 against S. aureus under low‐intensity illumination.

The Origin of Stokes Shift in Semiconductor Quantum Dots [PDF]
The mechanism of Stokes shift in semiconductor quantum dots is investigated by calculating the energy of the excitonic states. We have taken into account all possible contributions to the total electronic energy in the dot, i.e, dielectric mismatch between dot and surrounding medium, the effects of finite barrier height and electron-hole exchange ...

Off‐centering of cations in pavonite‐structured Ag1.75InSb5.75Se11 (AISS) breaks crystal symmetry, inducing Rashba‐like band splitting and high band degeneracy, thus enhancing Seebeck coefficients. Soft bonds between off‐centered cations and Se atoms increase phonon scattering, achieving low lattice thermal conductivity (0.22 W m−1K−1 at 723 K). Doping
