Summary: Intertidal fishing using block nets in mangroves has been of socio-economic and cultural importance to tropical fishing communities. This study investigated the catch composition and selectivity of intertidal fishing in northeastern Brazil and found spatiotemporal variability in catches and an efficient selectivity pattern of block nets. The findings emphasize the need for an ecosystem approach to fisheries management in coastal areas.

Summary: Area-selective atomic layer deposition (AS-ALD) is typically limited by the requirement of substrate materials with substantially different chemical properties. This study introduces a new process using self-assembled monolayers (SAMs) as inhibitors for achieving selective ALD on patterns with chemically similar materials. By utilizing differential reactivity of SAMs on various dielectric surfaces, the research demonstrates high selectivity for ZnO and Al2O3 ALD, opening up new possibilities for applications in next generation electronic devices.

Summary: A dry dielectric integration strategy enables the transfer of wafer-scale and high-kappa dielectrics on top of 2D semiconductors. An ultra-thin buffer layer is used to pre-deposit sub-3 nm thin Al2O3 or HfO2 dielectrics, which are then mechanically dry-transferred on top of MoS2 monolayers. The transferred ultra-thin dielectric film exhibits wafer-scale flatness and uniformity without any cracks, showing high capacitance, low leakage currents, and excellent transistor properties.

Summary: The early stages of silver nucleation on a monolayer epitaxial graphene (MEG) substrate were investigated, revealing a preference for odd-numbered clusters in adsorption and nucleation. Specifically, the Ag-3 trimer was identified as the most stable nucleus for subsequent growth of silver nanoparticles on MEG. The interaction between Ag adatoms and MEG was found to decrease as cluster size increased, with the stable nucleus identified as crucial for growth.

Summary: Large-scale nanoalloys of Co-Pt ranging from 3 to 7 nm in size were modeled using realistic atomistic potentials and Monte Carlo simulations, showing a tendency to reproduce bulk-ordered phases and structures on the surfaces. Certain surface structures were found to be incompatible with the core structure, resulting in disorder underneath. Mixed compositions were predicted on some surfaces, indicating a frustration in chemical ordering in nanoalloys.

Summary: The global optimization of metal cluster structures is a significant research area, with traditional deep neural network (T-DNN) method being a good approach but requiring numerous samples. We proposed a new method called DNN-TL that combines deep neural network and transfer learning, reducing the number of samples needed. Comparing to the T-DNN method, the DNN-TL method requires only a fraction of the samples and saves 70-80% of time for the global optimization of Pt9 and Pt13 clusters in this research. The effectiveness of transfer learning is rationalized by the larger amplitude of parameter changes in T-DNN compared to DNN-TL training. Additionally, the DNN trained by the DNN-TL method achieves even smaller fitting errors than the T-DNN method due to the reliability of transfer learning. Finally, the DNN-TL method successfully obtained the global minimum structures of Ptn (n = 8-14) clusters.

Summary: Area-selective atomic layer deposition (AS-ALD) allows for bottom-up patterning with atomic-level accuracy in conjunction with top-down patterning, showing inherent deposition selectivity without the use of inhibitory molecules. By incorporating combined ALD-etching supercycle strategies, the deposition selectivity can be further enhanced to approximately 5 nm, providing a practical approach for highly selective deposition in 3D bottom-up nanofabrication.

Summary: This study exploits the substrate-dependent selectivity of aminosilane precursors for oxides versus nitrides through chemo-selective adsorption. By performing AS-ALD of SiO2 on SiO2 substrates, it is possible to achieve inherent deposition selectivity of approximately 4nm using di(isopropylamino)silane as the precursor. Additionally, by implementing an ALD-etch supercycle, enhanced deposition selectivity greater than approximately 10nm can be achieved on both blanket- and patterned substrates.

Summary: This work presents an atomic-scale interfacial engineering strategy to construct highly-active electrocatalyst for glucose detection. Ni(OH)(2) nanosheets are decorated with an ultra-thin layer of Co9S8 using the atomic layer deposition (ALD) technique. After in-situ reconstruction, Ni@Co heterostructure consisting of Ni hydroxide nanosheets and CoOx clusters is obtained, which shows outstanding electrochemical glucose sensing performance. The presence of surface CoOx not only lowers the valence state of Ni, but also facilitates the deprotonation of Ni(OH)(2) to form NiOOH active species for glucose oxidation. The approach used in this work can be adapted to synthesizing high-performance electrocatalysts for other energy and environmental devices.

Summary: A physicochemical model of electrochemical potential distribution in a proton exchange membrane water electrolyser (PEMWE) stack is developed to understand the corrosive potential at the anode bipolar plate (BPP) and porous transport layer (PTL). The model predictions suggest that cheaper materials can be used instead of highly corrosion-resistant materials, which would significantly reduce the cost of green hydrogen.

Summary: Hollow MoS2 cubes and spheres were successfully synthesized using a one-step hydrothermal method with the hard template method. The hollow MoS2 cubes exhibited higher specific capacitance and energy density compared to the hollow MoS2 spheres. The symmetrical supercapacitors assembled with these hollow structures showed good performance and high capacity retention after multiple cycles. These findings suggest that controlling the pore structure and surface characteristics of MoS2 is crucial for enhancing its electrochemical properties.

Summary: The design of a solid electrolyte interphase (SEI) plays a crucial role in improving the electrochemical performance of anode materials. In this study, lithium difluoro(oxalate)borate (LiDFOB) is used as an electrolyte additive to form a protective SEI film on Li3VO4 (LVO) anodes. The addition of LiDFOB results in a dense, uniform, stable, and LiF-richer SEI, which enhances the Li-ion storage kinetics. The generated SEI also prevents further decomposition of the electrolyte and maintains the morphology of LVO anodes during charge/discharge processes. This work demonstrates the effectiveness of LiDFOB as a multi-functional additive for LiPF6 electrolytes and provides insights into SEI construction for high-performance LVO anodes.

Summary: In this study, we used density functional theory (DFT) calculations to investigate the interaction between model graphene oxide (GO) nanostructures and chlorine monoxide ClO. We aimed to understand the role of this highly oxidizing species in breaking C-C bonds and forming significant holes on GO sheets. Our results showed that C-C bonds in a single graphene oxide sheet can be broken through a simple mechanism involving the dissociation of two chemically attached ClO molecules. The formation of carbonyl groups and holes on the GO surface was also observed. This study provides important insights into the degradation of carbon nanotubes and the stability of GO during the myeloperoxidase (MPO) catalytic cycle.

Summary: In this study, the X-ray stability of five different lead halide perovskite compositions (MAPbI3, MAPbCl3, MAPbBr3, FAPbBr3, CsPbBr3) was investigated using photoelectron spectroscopy. Different degradation mechanisms and resistance to X-ray were observed depending on the crystal composition. Overall, perovskite compositions based on the MA+ cation were found to be less stable than those based on FA+ or Cs+. Metallic lead formation was most easily observed in the chloride perovskite, followed by bromide, and very little in MAPbI3. Multiple degradation processes were identified for the bromide compositions, including ion migration, formation of volatile and solid products, as well as metallic lead. CsBr was formed as a solid degradation product on the surface of CsPbBr3.

Summary: The stability of La1/3Sr2/3Fe1-xMnxO3-delta, a perovskite-type oxide, under reducing conditions is dependent on the manganese content. Increasing the manganese content leads to a decrease in stability. The behavior of iron and manganese in the oxide shows distinct differences, which can be attributed to the difference in the enthalpy of oxidation reactions. Additionally, the change in the La/Sr ratio affects the concentration of iron and manganese ions.
