Summary: A heterostructure BiFeO3/TiO2(Nt)Ti (BFOT) with p-type conductivity in the BFO film and n-type conductivity in the nanotubes was obtained by the atomic layer deposition method. The redistribution of Fe/Ti atoms and the formation of Aurivillius intermediate layered phase and local charge capture centers were observed after thermal treatment. The ferroelectric switching and the transition of the memristive structure were affected by the lateral displacement of the sample and the properties of the periodic signal. The compensation of static charge during resistive switching and the acceleration of structure restructuring with increasing voltage were found to influence the transport properties of the material. The correlation between surface static charge and piezopotential was shown through the analysis of piezoresponse force microscopy, electrostatic force microscopy, and fractal/multifractal dynamics. This new methodology can contribute to the understanding of the resistive switching processes in ferroelectric/semiconductor memristive structures.

Summary: This paper presents a detailed study on the hydrogen sensing capabilities of highly nanoporous black gold films. The films exhibit fast response and recovery times at low temperatures. Different levels of nanoporosity were prepared and tested to investigate the sensing properties, and it was found that nanoporous black gold is suitable for hydrogen sensing. The sensitivity of the film depends on its nanoporosity.

Summary: In this study, stable, efficient, and abundant c-a interfaces were formed by synthesizing crystalline FeP and amorphous MoP on foam ferrum. Theoretical calculations showed that the c-a interface optimized the overall electronic structure, enabling Mo and Fe to exhibit excellent HER and OER activity, respectively. The collaboration between the two types of active sites promoted overall water splitting. This research not only has implications for transition metal phosphides but also provides references for other types of catalysts.

Summary: In this study, metallic iridium nanoparticles supported on antimony-doped tin oxide were successfully synthesized using a facile microwave-assisted polyol method. By optimizing the synthesis parameters, highly active and durable electrocatalysts with narrow size distribution and homogeneous dispersion were obtained. The best catalyst, synthesized at 160 degrees C, showed 1.5 times higher activity and 2 times better stability compared to a state-of-the-art commercial catalyst.

Summary: This study introduces a novel electrocatalyst composed of Prussian blue (PB)-graphene quantum dot (GQD), which exhibits exceptional activity and stability. The symbiotic relationship between PB nanoparticles (NPs) and GQD accelerates electron transport, increases electrochemically active sites, and shortens mass transfer lengths. The presence of GQD mitigates the decomposition of PB NPs and ensures continuous electrocatalytic performance.

Summary: This study investigates the selectivity of acetylene over CeO2 supported single Pd catalyst and PDO-liganded Pd single catalyst using density functional theory calculations, microkinetic modeling, and ab initio molecular dynamics. The results show that PDO ligand stabilizes the single Pd catalyst through strong Pd-O/Pd-N interaction, leading to higher C2H4 formation selectivity.

Summary: In this study, the direct bonding between copper foil and PEEK film was achieved using nanosecond lasers. The surface of the copper foil was modified through UV/ozone and silane coupling treatments to enhance the interfacial bonding. The modified Cu/PEEK joints exhibited a significant improvement in peel strength, and the interaction between the treated copper foil and PEEK film was found to involve strong hydrogen bonding.

Summary: This study investigates the structural, optical, and superhydrophilic properties of zinc oxide pillars prepared by pulsed laser deposition at a high temperature. The results show that the samples prepared at high temperature exhibit larger crystallite size, higher surface roughness, improved light absorption, and enhanced superhydrophilicity. These properties are attributed to the increased interstitial zinc concentration and decreased oxygen vacancy concentration.

Summary: This study demonstrates the preparation of a high SERS activity and plasmonic photocatalytic properties nanoarray, SA-Ag/Au HCNAs, by combining Ag/Au hybrid coupled films with a sapphire array. The prepared SA-Ag/Au HCNAs show significantly enhanced plasmonic photocatalytic properties compared to pure Au and pure Ag. They also exhibit good stability and sensitivity as SERS substrates for probe molecules. This work provides a simple, low-cost, and scalable method for the preparation of hybrid coupled nanoarrays with potential applications in photocatalytic dye degradation, environmental monitoring, and biomedical analysis.

Summary: In this study, borophene quantum dots were scaffolded on TiO2 nanoparticles, resulting in enhanced photoelectrochemical water splitting activity. The optimized concentration of borophene quantum dots on TiO2 nanoparticles showed a lower effective absorption edge, indicating improved photoelectrochemical response. Various characterization techniques confirmed the presence and effect of borophene quantum dots on the nanocomposite. The results suggest that the BPQDs/TiO2 nanocomposite exhibits improved photoelectrochemical water splitting activity due to the synergistic effects of the individual components.

Summary: In this study, it was found that fitting the C 1s core level spectrum of graphene grown on Ir(111) using 200 peaks based on ab initio calculations, considering non-equivalent C atoms, does not improve fit quality. On the contrary, introducing a dependency of the Lorentzian width on the distance between C and Ir first-layer atoms can significantly enhance the quantitative fit quality, indicating the different electronic properties and density of states of C atoms in different regions of graphene.
