Summary: A large-scale synthesis method for phosphorescent carbon nanodots (CNDs) has been demonstrated via precursors' self-exothermic reaction at room temperature, showing comparable fluorescence and phosphorescence properties with other synthesis methods. The exotic atom doped sp(2) hybridized carbon core serves as an emissive center to facilitate the intersystem crossing, enabling tunable phosphorescence lifetimes from 193 ms to 1.13 s at different temperatures. This method opens up a new avenue for room temperature fabrication of phosphorescent CNDs.

Summary: The optoelectronic properties of functionalized graphene quantum dots were studied by simulating different shapes and types of functionalization. The results showed that the functionalization position and edge shape played important roles in the optical properties. The isomers with CH2 in the intermediate positions showed higher electronic transition energies and exciton delocalization. Complete passivation of rhombic GQDs resulted in the largest structural deformation and strongest red-shift. The substituents F, CH3, Cl, and Br caused a steady red-shift in the absorption energy, suggesting the dominance of steric effects.

Summary: In this study, a multi-color afterglow silicon-nanodot-based nanocomposite material was prepared using a simple hydrothermal method involving silane, dyes, and urea. The silicon nanodots formed in situ during the urea recrystallization process, accompanied by the formation of new covalent and hydrogen bonds. These nanodots were immobilized in the rigid network structure formed during urea recrystallization to deliver highly efficient phosphorescence. Orange and red afterglow materials were successfully synthesized based on the Förster resonance energy transfer principle. This study highlights the potential of constructing multifunctional phosphorescent materials from silane and provides a novel design principle for the synthesis of full-color afterglow materials.

Summary: Antibacterial clothes, based on the piezoelectric effect of ZnO nanowire arrays and their interaction with bacteria, have demonstrated high antibacterial efficiency. The piezoelectric effect generates interface electrons under bending, and the transfer of electrons between the bacteria and the nanowires inhibits bacterial growth and causes bacterial death. Approximately 70% of bacteria death is attributed to electron transfer, while the remaining 30% is due to puncturing by the nanowires. These fabrics exhibit remarkable antibacterial properties against Staphylococcus aureus and Escherichia coli, with a bactericidal rate of 99.99%, making them promising for practical applications. The demonstrated antibacterial fabrics in this study lay a solid foundation for the development of antibacterial clothes.

Summary: In this study, the lattice contraction and electron-rich surface of Pd were successfully regulated by doping low electronegative metal M (M = Zn, Ni, Co, or Cu), leading to an enhanced selectivity for the conversion of benzene to cyclohexylbenzene. Mechanistic investigation revealed that PdZn promoted the asymmetric adsorption and activation of benzene to cyclohexene, and regulated its moderate adsorption. This work provides new insights into the intrinsic regulation of tandem reactions with one key intermediate.

Summary: Humidity sensors based on hexagonal boron nitride (h-BN) nanosheets have been fabricated with ultrahigh sensitivity, rapid response/recovery time, and long-term stability. The sensors show an exceptional sensitivity of 28,384% at 85% relative humidity (RH) and outperform most reported humidity sensors. The high sensitivity is attributed to the hydrophilic functional groups absorbed on the h-BN nanosheets, enabling contactless applications such as Morse code messaging and human writing and speech recognition. This work highlights the great potential of h-BN nanosheet-based humidity sensors for future contactless sensing devices.
