Summary: We present a mechanistic study on the collision and self-terminating oxidation of individual Ag nanoparticles in aqueous solution. The collision-induced oxidation converts Ag to Ag2S, forming a thin layer independent of the original particle size. As the Ag2S layer grows, the ohmic potential loss increases, eventually leading to the sudden cessation of the oxidation reaction. The resulting voids occupy around 40% of the original particle volume.

Summary: The study investigates the growth mechanism of semiconductor magic-sized clusters, with a particular focus on CdSe nanocrystals. By synthesizing a series of gradually increasing magic-sized nanocrystals and developing a microscopic model, it reveals the layer-by-layer growth mechanism of zinc-blende crystallites and the source of special stability in these nanocrystals. The analysis also identifies strong similarities with the growth of semiconductor nanoplatelets, and exploits this to further increase the size range of magic-sized nanocrystals.

Summary: Hybrid nanocrystals with multiple components and junctions have been of great interest due to their promising properties. In this work, two types of Au-Ag2S-Cu2-xS NCs with disparate interfacial features are demonstrated. The first type is prepared through a routine two-step method, while the second type is achieved by a facile one-pot synthesis procedure. The formation of these NCs is attributed to an underlying mechanism involving the evolution of different core-shell structures before the final complex nanostructure is built.

Summary: The new collector HIP emulsion significantly reduces oil consumption and shows higher flocculation and flotation efficiency compared to kerosene. High-shear pulping promotes the overall flotation rate of HIP emulsion, but may also lead to degradation of its flocculation ability.

Summary: Liquid air energy storage (LAES) has been considered as a large-scale electrical storage technology, with a baseline LAES achieving a high electrical round trip efficiency at high charging pressures. The study also highlights the potential of harnessing excess heat in the baseline LAES to achieve high efficiency even at lower charging pressures. A hybrid LAES system is proposed to provide multiple functions and has shown promising results in terms of efficiency, energy savings, and reduced carbon dioxide emissions. These findings indicate that small-scale LAES systems could operate best at lower charging pressures and have great potential for applications in decentralized micro energy networks.
