Summary: With the use of solvent-induced self-assembly technique, we have developed multifunctional nanoparticles for imaging and treatment of breast cancer. These nanoparticles combine the bioimaging ability of gold nanoclusters and the photothermal properties of copper sulfide nanoparticles. By modifying the nanoparticle surfaces with folic acid, the nanoparticles can target folate receptors overexpressed in breast cancer cells. In vitro experiments have shown that these composite nanoparticles have excellent fluorescence imaging ability and a better capability to kill MDA-MB-231 cells than single drug or photothermal treatment alone. This multifunctional system, combining fluorescence imaging, photothermal treatment, and targeted drug delivery, shows great potential for cancer diagnosis and treatment.

Summary: Supraparticles with high structural order and coloration from uniform, polyhedral metal-organic framework (MOF) particles were prepared through confined self-assembly processes. The study showed that the color of supraparticles changes with the size and internal structure of anisotropic building blocks, and angle-dependent coloration is attributed to the presence of ordered, onion-like layers at the outermost regions. Surprisingly, all supraparticle dispersions exhibit visible macroscopic coloration, indicating that local ordering is sufficient to generate interference effects.

Summary: By precisely controlling the interfacial interaction between colloidal nanoparticles and the oil/water interface, we successfully assembled Mackay icosahedral and regular tetrahedral colloidal clusters from gold nanoparticles. The transformation from Mackay icosahedral clusters to regular tetrahedral clusters was achieved by increasing the proportion of hydrophilic P2VP ligands on the surface of gold nanoparticles. The formation mechanism of these regular polyhedral colloidal clusters was also revealed, showing that it is determined by both entropy and interfacial free energy.

Summary: In this study, a novel approach was proposed to fabricate Au@MnO2 core/shell assembled nanosheets utilizing the localized surface plasmon resonance (LSPR) effect of gold nanoparticles. The reduction of KMnO4 to MnO2 on Au NPs under 520 nm light resulted in the gradual assembly into thin sheeted morphology. The significance of irradiation conditions and surface functional groups, particularly the 520 nm light and citrate group, in the formation of stable Au@MnO2 core-shell assembled nanosheets was systematically studied. The controllable, green, and facile nature of this approach allows for its extension to synthesize other complex nanomaterials for various applications.

Summary: In this study, the self-assembly of N-heterocyclic olefins (NHOs) on gold surface was investigated using experimental and computational methods. It was found that NHOs can self-assemble into dimers, trimers, and tetramers, forming stable monolayers. The study also revealed that NHOs can adsorb on gold surface in a flat-lying geometry through coordination with gold adatoms, and the surface interaction can be further increased by functionalizing the backbone with methyl groups, leading to enhanced thermal stability and impact on work-function values.

Summary: The stable electrochemical potential window of thiolate self-assembled monolayers (SAMs) on Au, Pt, and Cu electrodes is studied systematically in aqueous electrolyte systems. The reductive stability is found to depend on the binding strength of sulfur and competitive adsorption of hydrogen, while the oxidative stability is related to each surface's propensity toward surface oxide formation. The stability of SAMs is also influenced by factors such as SAM defects, intermolecular interactions, SAM thickness, and the ability to directly oxidize or reduce the non-sulfur part of the SAM molecule.

Summary: Surface-enhanced Raman scattering (SERS) spectroscopy provides sensitive rapid detection of molecules. A simple and effective method using seed-assisted electrodeposition is developed for fabricating a 3D SERS substrate composed of multilayer Au nanoparticles. The resulting multilayer Au nanoparticles-assembled film shows high SERS sensitivity, good spectral uniformity, and reproducibility, with a low detection limit for rhodamine 6G. Moreover, it is also effective in detecting organic pollutants such as crystal violet and methylene blue.

Summary: Efficient, stable, and inexpensive oxygen evolution reaction (OER) catalysts are explored for the practical application of seawater electrolysis. In this study, CoSe2@CoO/CF catalysts are prepared using a simple and scalable one-step electrodeposition method, and their OER performance is extensively investigated. The CoSe2@CoO/CF catalyst (273 mV) exhibits significantly higher activity than the IrO2 catalyst (435 mV). It can be operated steadily at high current densities (100 mA cm-2) for over 200 hours in 1.0 M KOH + seawater. Moreover, the catalyst shows excellent selectivity with a Faraday efficiency of approximately 98% for OER, while the ClO- concentration is extremely low (1.312 x 10-7 mol L-1) as measured by UV-visible characterization. The impressive performance can be attributed to the urchin-like heterogeneous structure of the catalyst with abundant active centers, as well as the facilitation of para-site electron transfer due to the strong overlap between the Co 2p orbitals of monometallic bi-compound catalysts.

This study discovered the periodic self-organization behavior of porous copper at the initial stage of industrial large-current electrodeposition. The findings suggest the important contribution from intrinsic self-organization dynamics of intermediate to the formation of porous metal materials with high activity or surface area in industrial scale.

Summary: Electrochemical methods are commonly used to prepare functional surfaces using optimized solutions. However, there is a growing need for selective deposition methods that can utilize more complex solutions in order to improve resource efficiency. This study demonstrates how electrochemically generated Cu1+ species can assist in the recovery of gold nanoparticles from Au-Cu-Cl solutions. By employing the electrochemically assisted reduction (EAR) method, the current efficiency can be improved, the loss of deposits due to corrosion can be minimized, and narrow particle size distributions can be achieved, even at high NaCl concentrations.

Summary: The addition of Nb and Mo to CoCrFeNi high entropy alloys improves their oxidation resistance due to the formation of a new Laves phase that hinders the diffusion of metal cations. The duplex phase structure of FCC and Laves contributes to the inhibition of oxygen ion diffusion, leading to enhanced anti-oxidation properties.

Summary: LiNixCoyMn1-x-yO2 (NCM) is a critical cathode material for lithium-ion batteries in electric vehicles. The aging of cathode/electrolyte interfaces leads to capacity degradation and long-term cycle instability. A novel neural network model called ACGNet is developed to predict electrochemical stability windows of crystals, allowing for high-throughput screening of coating materials. LiPO3 is identified as a promising coating material with high oxidation voltage and low cost, which significantly improves the cycle stability of NCM batteries. This study demonstrates the accuracy and potential of machine learning in battery materials.

Summary: In this study, a bifunctional electrode host design consisting of carbon nanofibers implanted ordered porous Co-decorated Al2O3 supported on carbon nanotube film (CNTF) was proposed to address the shuttling effect of lithium polysulfides (LiPSs) and dendrite formation of metal lithium anode in lithium-sulfur (Li-S) batteries. The electrode exhibited excellent conductivity, efficient confinement of LiPSs, and catalytic conversion performance, resulting in high initial capacity and good capacity retention during cycling. As an anode, the electrode showed excellent Li+ diffusion performance and uniform lithium growth behavior, achieving a dendrite-free lithium electrode. The flexible pack cell assembled from these electrodes delivered a specific capacity of 972 mAh g(-1) with good capacity retention.
