Summary: Colloidal cesium lead halide perovskite nanocrystals offer easy synthesis and color-pure photoluminescence, but their stability issues and unwanted reactivity pose challenges. The chemistry of these nanocrystals is characterized by intricate patterns of shapes and compositions, and they readily transform under physical stimuli or chemical agents. The ability of these nanocrystals to undergo ion exchanges and trade neutral species with the surrounding environment allows for precise control of their properties and structure.

Summary: In this study, the temperature-dependent absorption and photoluminescence spectra of CsPbBr3 perovskite nanoplatelets were investigated. A temperature-dependent Stokes shift ranging from 26 to 41 meV was observed, which was attributed to the exciton fine structure due to the difference in peak width. The large Stokes shift observed here is proposed to be an intrinsic property of 2D perovskites.

Summary: In this study, Mn-doped CsPbBr3 perovskite nanoplatelets and nanocubes with different Mn/Pb molar ratios were synthesized and the effects of NPL thickness on the Mn2+ luminescence properties were investigated. The results showed that the excitonic peak and morphology of the NPLs evolved with increasing Mn2+ ion doping concentration, and the photoluminescence quantum yields (PL QYs) were greatly enhanced. In addition, the passivation of defect states and morphology transformation also influenced the PL lifetime and deep defect states of the Mn2+ emission. These Mn-doped CsPbBr3 NPLs and nanocubes show great potential for application in white light-emitting diodes.

Summary: Microwave-assisted gas-phase conversion on structured catalysts is a promising technology in heterogeneous catalysis, capable of avoiding non-selective gas-phase reactions. Scaling-up from laboratory to a stable operation with a 150-fold higher feeding rate has potential, but main obstacles include catalyst deactivation and the design of microwave cavity. Energy consumption and scaling factor show non-linearity, highlighting the importance of microwave cavity design.

Summary: Carbon nanodots (CNDs) are used as fluorescent nanosensitizers to enhance the photocatalytic response of semiconductors beyond the ultraviolet range. The addition of nitrogen heteroatoms to the carbogenic network of CNDs improves their photostability and optical properties. Laser pyrolysis is a versatile technique for synthesizing N-doped CNDs by using a liquid solvent containing nitrogen as the carbon precursor. These N-doped CNDs exhibit enhanced photoactivity when combined with P25 nanoparticles for the conversion of methyl orange under white LED illumination, generating various reactive oxygen species.

Summary: This study sheds light on the interplay between homogeneous and heterogeneous catalytic processes in the field of bio-orthogonal catalysis within tumour microenvironments. A bimetallic catalyst nanoparticle containing Cu and Fe species was designed and investigated. The results reveal that homogeneous processes initiated by Cu-GSH interactions are responsible for cell death effects, and the remaining CuFe nanoparticle acts as an active catalyst to supply oxygen in the oxygen-deprived tumour microenvironment. The combined mechanisms of heterogeneous and homogeneous catalysis show high efficiency in selectively killing cancer cells.
