Summary: Urea and its derivatives are commonly used as ligands in coordination and bioinorganic chemistry, but have not been widely explored as precursors for organic-inorganic nanomaterials. This study presents the synthesis and structure characterization of two novel organozinc ureate complexes, expanding the scope of urea-zinc chemistry. The mechanochemical approach used in this research allows for rapid and sustainable synthesis of hybrid nanomaterials from organometallic precursors, with potential applications in nanoscience and materials chemistry.

Summary: We present a new synthetic method to prepare high-quality InP-based quantum dots (QDs) with tuneable emission, by using a solid, air- and moisture-tolerant primary phosphine as a group-V precursor. This method offers a significantly simpler synthetic pathway compared to the current state-of-the-art precursors used in phosphide quantum dot synthesis, which are volatile, dangerous, and sensitive to air, such as P(Si(CH3)(3))(3).

Summary: This study reports on the elaboration of translucent ZnGa2O4 ceramics through an innovative process. The researchers used the lixiviation of glass-ceramics to obtain ZnGa2O4 nanocrystals, which were then sintered into bulk ceramics using Spark Plasma Sintering (SPS). Despite the slightly lower transmittance compared to the theoretical value, these results are promising and open up new possibilities for transparent ceramic processing.

Summary: Through experimental and theoretical calculation studies, we find that the Cu{110} facet is the most active facet for ZnO-Cu interfacial catalysis in CO2 hydrogenation to methanol, and the Cu{100} facet is the most active facet for both ZnO-Cu interfacial catalysis and Cu catalysis in the RWGS reaction. Although the ZnO-Cu interface has higher catalytic activity, the RWGS reaction mainly occurs on the bare Cu surface.

Summary: Shape control of calcium carbonate particles has been challenging due to its low dispersibility and limited ligand-binding ability. However, the transition behavior from nanoparticles to microscale superstructures has been successfully captured in response to changes in solvent dispersibility. The presence of water in the reaction solution is crucial for triggering the transition and enabling the formation of well-defined superparticles. These ligand-free superstructures show high tolerance to small molecules and have potential for drug delivery applications.

Summary: Due to the wide application of ultraviolet light in various fields, there is an urgent need for ultraviolet photodetectors with high sensitivity and fast response. Traditional ZnO-based UV photodetectors are limited in response speed by the carrier mobility and electrical resistance caused by external circuits. A fast-response fiber-optic UV photodetector is proposed, utilizing an all-optical detection method and a ZnO micro-pillar as a Fabry-Perot interferometer. The device achieves higher sensitivity through the introduction of a discontinuous Ag film with an island-like structure, and exhibits a fast response with a rise time of 35 ns and a decay time of 40 μs. The compact and flexible structure of the device, along with its immunity to electromagnetic interference, opens up new possibilities for the next generation of photodetection devices.

Summary: Bandgap engineering and quantum confinement in semiconductor heterostructures allow for fine-tuning of material response to electromagnetic fields and light. However, forming semiconductor heterostructures on lattice-mismatched substrates has been a challenge. This study demonstrates the successful van der Waals epitaxy of 2D GaSe and InSe heterostructures on silicon and sapphire substrates with different lattice parameters. The GaSe/InSe heteroepitaxy enables the growth of quantum wells and superlattices with photoluminescence and absorption related to interband transitions.
