Summary: This study presents single-shot electron velocity-map images of nanoplasmas generated from doped helium nanodroplets and neon clusters by intense laser pulses, revealing different signal types depending on cluster size. The inner electrons show a nearly circular shape and follow a simple power-law dependence, while the presence of an external electric field significantly affects the evolution of the nanoplasma.

Summary: Studies have shown that complex spatial distributions of charge, consisting of micrometer-scale regions of both positive and negative charge, are produced on insulator surfaces when they become electrostatically charged. Controlled Kelvin force microscopy experiments on microfabricated interdigitated electrode systems demonstrate that wetting a surface by a liquid followed by evaporation in an electric field can lead to neighboring micrometer-scale regions of opposite charge polarities, which remain stable long after the electric field is removed. Local electric fields, possibly due to existing charge on the surface, are suggested to act in conjunction with liquid evaporation to contribute to the creation of charge mosaics.

Summary: The resonance-absorption condition in laser-nanoplasma interactions is wavelength dependent. It is found that this condition is invalid in the middle-infrared spectral range but valid for visible and near-infrared wavelengths. Molecular dynamic simulations reveal that the transition in the resonance condition is caused by a decrease in electron scattering rate and an increase in cluster outer-ionization contribution. An expression for the nanoplasma resonance density is derived based on experimental results and simulations. These findings are significant for a wide range of plasma experiments and applications, particularly in the extension of laser-plasma interaction studies to longer wavelengths.

Summary: Through analysis of electronic structures, this study investigated the contact charge transfer mechanism at the liquid-solid interface, confirming that the surface electrostatic charge perturbation-induced outer shell charge transfer is more significant than inter-bonding-orbital charge transfer, revealing multiple factors involved in charge transfer. The pinning factor provides a more direct visualization of charge transfer, offering critical guidance for future exploration of contact electrification induced charge transfer systems.

Summary: The electrostatic charging states of insulating polymer surfaces were analyzed using sum-frequency generation (SFG) spectroscopy. For negatively charged polypropylene, the SFG peak amplitudes increased significantly with increasing surface potential, indicating a direct influence of the electrostatic charges on the SFG signal intensities. In organic thin films stacked on top of PMMA, an increase in the SFG signal of buried PMMA was observed, indicating the extension of the electrostatic field into the bulk direction. Additionally, the visualization of charge location and distribution was demonstrated using SFG intensity variations.

Summary: Advancements in satellite imagery and machine learning can help address data scarcity and inference challenges. Using the example of the expansion of the electrical grid in Uganda, this study demonstrates how satellite imagery and computer vision techniques can be used to develop local-level livelihood measurements and machine learning-based inference techniques provide more reliable estimates of the impact of electrification. The findings show that grid access in rural Uganda improves village-level asset wealth and doubles the growth rate compared to untreated areas.

Summary: In countries with a large share of population in energy poverty, appliance and electricity demand are expected to increase as income rises. The level of adoption of electrical appliances varies significantly by country, appliance type, climate, and income, with a stable share of electricity used for entertainment in all four countries and socio-economic futures. Achieving universal access to electricity can increase total electricity demand but decrease average per capita consumption.

Summary: A new post-treatment antistatic strategy is demonstrated to significantly reduce the accumulation of static charge by controlling the spatial distribution of tribopositive and tribonegative regions. On-site interface charge neutralization between tribopositive and tribonegative regions leads to rapid charge decay, making it especially useful in some extreme scenarios.

Summary: Epoxy-amine resins are commonly used as binders in corrosion protective coatings, but oxidative deterioration limits their performance. This study investigates the early stages of oxidative degradation in buried polymer/metal interfaces using innovative approaches, such as introducing iron oxide interfaces and using nanoscale cross-sectional infrared analysis. The research shows that oxidation initiates at the polymer-metal interface and progresses slowly into the polymer, resulting in chemical gradients of < 400 nm after exposure to mild thermal aging conditions.

Summary: The hypothesis of this study is that interphase properties in composites, adhesives, and protective coatings can be predicted based on the interfacial interactions between polymeric precursor molecules and the inorganic surface during network formation. The researchers applied conventional analysis techniques, atomic force microscopy coupled with infrared (AFM-IR), and molecular dynamics simulations to investigate the molecular interactions and properties of nanocomposite specimens. The findings revealed the presence of under-cured interphase regions and the excess of epoxy functionality near the particle surfaces, and demonstrated the driving force for molecular orientation and raised Tg values in the goethite composite samples.

Summary: This study investigated the influence of additional pigmentation on the leaching of inhibitor pigments and found that the addition of soluble/sparingly soluble pigments increased the leaching rate. This is attributed to the formation of clusters comprised of both the inhibitor pigment and the additional pigment, which introduces transport paths in the organic coating and facilitates the leaching of the inhibitor pigment.

Summary: Understanding the interactions at the polymer/metal oxide interface is crucial for improving the performance of corrosion resistant coatings. In this study, we investigated how the structure of a crosslinker affects its adsorption and incorporation into the network. We found that the crosslinker has two distinct binding modes on both hematite and goethite, with hydrogen bonding modes observed on goethite limiting interconversion between the two. Additionally, we discovered that binding persists in fully cured composite samples, determining the levels of residual amine. Unlike previous studies using a different crosslinker, we found that the glass transition temperature (Tg) of the composite specimens is independent of the added hematite and goethite volumes.

Summary: Pigmentation can worsen water uptake in protective paints, leading to delamination, swelling, and plasticization. Poor adhesion, hygroscopic interphase near pigment particles, and internal stress are the potential mechanisms involved. This study used nanoscale chemical mapping and nanothermal analysis to investigate these mechanisms in model coatings. The findings showed no chemical interphase near wax-coated particles, while attenuated thermal expansion and increased Tg values of the polymeric binder indicated favorable polymer-pigment interaction and increased internal stress.
