Summary: This study reports a straightforward method for synthesizing red, green, blue and violet emitting AuNCs in pure ethylene glycol with the addition of aniline or indole. By using advanced microscopy, mass spectrometry, and spectroscopy techniques, different sizes of AuNCs were identified and found to emit pure white, blue, green, and violet luminescence. The AuNCs were made water soluble and stable while preserving their photo-physical characteristics by capping them with a thiopegylated ligand shell bearing a carboxylate, amine or biotin. These findings have potential applications in biolabeling, hyperspectral sensing, and display technology.

Summary: A one-pot hydrothermal procedure was used to develop magnetic cellulose nanocrystal (MCNC) from microcrystalline cellulose (MCC) in the presence of ferric chloride, ferrous chloride, urea, and hydrochloric acid. The composite of MCNC with magnetite (Fe3O4) showed potential as an adsorbent for water treatment and environmental remediation. Post-treatment with chloroacetic acid (CAA), chlorosulfonic acid (CSA), or iodobenzene (IB) improved the adsorption capacity of MCNC for doxycycline hyclate (DOX) by introducing carboxylate, sulfonate, and phenyl groups.

The adsorbent showed high adsorption capacity for methylene blue, fitting well with Langmuir isotherm and pseudo-second-order kinetic models. The adsorption process was found to be spontaneous and endothermic, and the mechanism was attributed to electrostatic interaction.

Summary: In this study, the photoluminescence (PL) origin of water-soluble CuInS2 (CIS) quantum dots (QDs) was investigated by preparing CIS and CIS/ZnS QDs and studying their temperature dependence. The results showed that the PL intensity of both CIS and CIS/ZnS QDs increased with temperature, which could be quantitatively explained by thermally activated nonradiative recombination processes. Additionally, the temperature dependence of the Stokes shift and PL decay time differed between CIS and CIS/ZnS QDs, with the unusual behavior of CIS/ZnS QDs attributed to carrier localization at the core/shell interface at low temperatures. The temperature dependence of the PL decay time of CIS/ZnS QDs could be quantitatively explained by a phenomenological rate equation model considering carrier localization at low temperatures.

Summary: This study presents a one-pot synthesis method for precisely shaped and monodispersed single-crystalline gold nanospheres with an ultrasmooth surface and tunable sizes, achieved through a unique morphology change from octahedral to spherical shape induced by surface self-polishing etching. The localized surface plasmon resonance property of the gold nanospheres with different sizes matches well with theoretical predictions due to their perfect spherical shapes and uniform sizes. This synthesis protocol demonstrates extreme stability in large-scale production of gold nanospheres solution, stored in ethylene glycol for over 24 months, due to isotropic surface tension.

Summary: A handedness controllable circularly polarized luminescence (CPL) system was successfully constructed by tuning the supramolecular self-assembly. The planar structure of the solvent N,N-dimethylformamide co-assembled with CPT-A, resulting in a change in the glum from -0.0082 to +0.0085 with increasing water content. In the non-planar solvent hexafluoroisopropanol, the glum was amplified to 0.034 with increasing water content. Moreover, CPT-A could react with glutathione to make the anticancer drug CPT more toxic to cancer cells.

In this study, Cu metal nanoparticle catalysts of different sizes were prepared and encapsulated in Zn, N-doped carbon supports to investigate the size effect on CO2RR reactivity. The results show that the size of Cu crystallites affects the performance of CO2RR, which is attributed to the interaction between metal nanoparticles and their supporting matrix.

Summary: Amorphous CoNiS nanosheets are synthesized on nickel foam (NF) through a facile structure evolution strategy and demonstrate advanced performance in water splitting at high current densities. This is attributed to the sufficient active sites exposed by the flexible amorphous configuration. The hydrophilicity and aerophobicity of a-CoNiS/NF promote surface wettability and avoid bubble aggregation, facilitating mass transfer and achieving low overpotentials for hydrogen and oxygen evolution reactions under alkaline conditions.

Summary: This study investigates the dynamic structural transformation induced by MXene for cobalt-based electrocatalysts containing various oxyanions during the hydrogen evolution reaction (HER) activation process. The in situ coordination of borate induces the formation of asymmetric active centers, enhancing the HER activity. Theoretical calculations reveal that the transfer of electrons from Co sites to coordinated oxyanions modulates the electron density of active sites, reducing the energy barrier for water dissociation and hydrogen adsorption.
