Summary: A versatile synthetic route was reported for the preparation of nearly monodispersed spherical gelatin-silica hybrid nanoparticles. The method is effective for both gelatin type A and B, using different alkoxysilane coupling agents. ICPTES is more suitable for producing uniform nanospheres with narrow size distribution, while GPTMS increases the surface roughness of the particles. The hybrids are thermo-sensitive and can be used for thermally controlled drug-delivery systems.

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: 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: Hexagonal boron nitride (hBN) has been recognized as a stable 2D covalent compound, which can be challenging to chemically functionalize, but can be fluorinated using a gas-phase technique to reduce bandgap, exhibit semiconducting behavior, and improve thermal and friction properties. The enhanced friction properties of fluorinated hBN are attributed to reduced inter-planar interaction energy by electrostatic repulsion of intercalated fluorine atoms between hBN layers without disrupting the in-plane lattice, paving the way for applications in magnetism and nanoscale electronic devices.

Summary: Galvanic replacement reactions are a reliable method for transforming monometallic nanotemplates into bimetallic products with complex nanoscale architectures. The replacement of bimetallic nanotemplates can lead to even more complex multimetallic products, with final nanocrystal shapes and architectures depending on various processes such as Ostwald ripening and the Kirkendall effect. Studies have shown that replacement products often lose Cu more quickly than Pd, maintain the crystal structure of the original template, and grow a new phase on the sacrificial template, resulting in diverse product morphologies including faceting, core@shell, and Janus-style particles.

Summary: To mimic the burrowing activities of earthworms and improve soil porosity, researchers have developed a degradable actuator that can dig, grab, and lift soil when it receives rainfall. This scarifying actuator is made of degradable cellulose acetate and uncrosslinked polyacrylamide, which can bend rapidly and remarkably when absorbing water. Patterning polyacrylamide within cellulose acetate using reversible surface protection technique enables the actuator to generate complex deformations. This water-induced deformation is well-preserved in soil, making it suitable for rain diffusion and root breath.

Summary: By introducing organic semi-conducting molecules onto CsPbBr3 nanocrystals, they exhibit a high photoluminescent quantum yield (PLQY) of 82% and extremely high stability in harsh conditions. This stability is attributed to the strong interaction and moderate photocarrier transfer between the quasi type II heterostructure formed by the molecule and CsPbBr3. This advancement opens up promising prospects in perovskite-based display technologies.

Summary: This study focuses on manganese doped CdS thin films synthesized by chemical bath deposition. The incorporation of Mn2+ cations in CdS was found to influence the crystalline structure, morphology, and optoelectronic properties. Doped thin films exhibited a uniform hexagonal structure, changed growth orientation, and showed scale-like and needle-like morphologies. The bandgap and rectification speed of Schottky diodes were modified by introducing manganese. This study suggests the potential for affordable high-speed optoelectronic devices.
