Summary: This paper proposes the synthesis of ultrathin Ag@NiO core-shell nanowires to enhance the thermal, electrical, and chemical stability of silver nanowire networks. The encapsulated Ag@NiO nanowires show low sheet resistance, high transmittance, and improved resistance to heat, humidity, and corrosion. A stable free-standing transparent conductive nanomembrane is fabricated by embedding the Ag@NiO nanowire network in an ultrathin polyimide, which can be used for skin-attachable pressure sensing.

Summary: In this study, the effect of Pt shell thickness and Ag content in the surface layer on the oxygen reduction reaction (ORR) activities of Ag@Pt core@shell nanoparticles (NPs) is discussed. The electrochemical activity measurements show a remarkable dependency between the Ag content in the shell and the ORR activity. Further analysis using high-resolution transmission electron microscopy, X-ray photoelectron spectroscopy, and X-ray diffraction reveals an increase in Pt shell thickness and the correlation between the absence of Pt-H adsorption/desorption peaks in cyclic voltammetry and the presence of Ag in the surface layer.

Summary: A new method for deuterating (hetero)aryl bromides using Ag2CO3 as catalyst and D2O as deuterium source is disclosed in this study, which is highly efficient and easy to manipulate. In comparison to traditional multistep syntheses, this method allows for one-step deuterium labeling of various bioactive druglike molecules and key intermediates of functional materials. Additionally, this method demonstrates unique site-selectivity in comparison to existing transition-metal-catalyzed processes, leading to multideuterated (hetero)aryl bromides in one step.

Summary: Photocatalytic production of hydrogen peroxide (H2O2) using multi-metal composite sulfide (Ag-CdS1-x@ZnIn2S4-x) with double S vacancies and hollow core-shell Z-type heterojunction structure achieves high productivity. The unique hollow structure improves light source utilization, while the Z-type heterojunction promotes carrier separation and the core-shell structure increases interface area. The presence of dual disulfide vacancies provides good selectivity for 2e- O2 reduction to H2O2. This work provides new insights into selective two-electron photocatalytic H2O2 production and offers ideas for the design of active energy conversion photocatalysts.

Summary: We developed a chemical process to fabricate a highly sensitive SERS fiber probe. The probe was made by self-assembling Au@Ag core-shell nanorods on polyelectrolyte multilayers, with the silver layer thickness controlled for optimal performance. The probe showed ultra-high sensitivity (down to 10(-10) M) and good reproducibility and stability when the silver layer thickness was 8.57 nm. Additionally, we investigated the electromagnetic field distribution of the probe and found the strongest enhancement in the fiber core. The SERS fiber probe has potential applications in ultra-trace detection in biomedical and environmental fields.

Summary: Gold-silver core-shell nanorods exhibit tunable plasmonic response over the visible spectrum by varying the thickness of the silver shell. The chiral arrangement of these nanorods, achieved through DNA origami design, enables the transfer of tunable plasmon resonance frequencies into circular dichroism signals covering a wide spectral range from 400 nm to 700 nm. This approach could have significant implications for the development of better sensors and metamaterials with tunable optical response in the visible region.

Summary: We propose a method for synthesizing well-controlled core-shell nanoheterodimers (NHDs) based on single bimetallic Au@M (M = Au, Ag, Pd, Pt) nanodots (BNDs) grown on TiO2 nanoparticles (NPs). The process involves a two-step laser-assisted deposition. The first step uses a focused UV laser to nucleate and grow a single core nanodot (ND) with quantitatively controlled size. In the second step, a new metal precursor is added to the Au-TiO2 NHDs and a second laser deposition takes place on the first gold NDs. The synthesized NHDs exhibit different growth patterns depending on the metals involved.

Summary: Fluorine-19 MRI is a promising technique for biomolecular imaging, but its poor sensitivity has been a limitation. To increase the sensitivity, increasing the number of fluorine nuclei per probe and decreasing their relaxation time are necessary. This can be achieved by using fluxional lanthanide complexes with open coordination sites. The results show that these complexes can bind fluorinated phosphonates, resulting in chemically equivalent fluorine nuclei and improved imaging performance.

Summary: A novel pyrene-appended Schiff base probe L with aggregation-induced emissions (AIE) was synthesized and employed for sequentially detecting Cu2+ and CN-. Probe L induced excimer formation in the presence of Cu2+ and this process was reversed by adding CN-. The stoichiometry, binding atoms, and complex reversibility of the excimer complex L-Cu2+-L* were confirmed through various analyses, and the association constant of L to Cu2+ was determined. The practicality of Cu2+ and CN- detection was demonstrated using a TLC plate and a blended polymer membrane, and the low toxicity of probe L allowed for its application in detecting Cu2+ and CN- inside HeLa cells.

Summary: Porous methylammonium lead tribromide (MAPbBr(3)) nanowires were synthesized using a self-template-directed method, with dimensions of 13±3 μm in length and 700±100 nm in width. The nanowires displayed uniform crystallinity and high porosity, as confirmed by X-ray diffraction, scanning electron microscopy, and transmission electron microscopy. The single nanowires showed linear behavior in the current-voltage (I-V) characteristics and had high conductivity, hole concentration, and hole mobility. The porous nanowires also exhibited stability and insensitivity to environmental effects, and their conductivity could be modulated through doping or substituting mechanisms when exposed to heavy metal ions. Additionally, the single nanowire device was used as an electrochemical sensor for detecting four metal ions, demonstrating great sensitivity due to its wide dynamic range in electrical conductivity.
