Summary: This study reports for the first time the photocatalytic activity of ferroelectric CIPS for the chemical deposition of silver nanostructures (AgNSs). The shape and spatial distribution of AgNSs on CIPS can be controlled by adjusting layer thickness, environmental temperature, and light wavelength. The ferroelectric polarization in CIPS plays a critical role in the photodeposition process. In addition, AgNS/CIPS heterostructures prepared by photodeposition show excellent resistance switching behavior and surface enhancement Raman Scattering activity.

Summary: Confining silicon within carbonaceous materials is a typical strategy to solve the issues of pulverization and capacity decay in silicon-based electrodes for lithium-ion batteries. However, the uneven distribution of silicon particles in the carbon matrix often decreases the benefits of silicon/carbon composites, resulting in unstable capacity and rate. The use of a porous carbon material with a unique gridding structure allows for fast and stable lithiation/delithiation of the silicon particles.

Summary: Ground-level ozone has negative impacts on human health and ecosystems. In California's San Joaquin Valley (SJV), the effectiveness of controlling precursor emissions on ozone levels depends on the time and location of the emissions. The study shows that the impacts of local emissions and emissions from surrounding areas are similar in magnitude in the SJV. Same-day emission impacts are mainly attributed to local sources, with the most influential emissions of volatile organic compounds (VOCs) and nitrogen oxides (NOx) occurring in the morning and early afternoon. The influence from emissions in the Sacramento Valley peaks 5-6 hours later than emissions from the San Francisco Bay area for the northernmost SJV receptor, but this difference diminishes for receptors located further downwind. There is a shift towards NOx-sensitive conditions in the afternoon for all receptors except the southernmost one.

Summary: The thermal instability of silver nanowires leads to increased electrical resistance in AgNW networks. Understanding the relationship between structural and electrical properties of AgNW networks is crucial for their integration as transparent electrodes in flexible optoelectronics. In situ X-ray diffraction measurements were used to study the crystallographic evolution of Ag-specific Bragg peaks during thermal ramping, revealing differences in thermal and structural transitions between bare and SnO2-coated AgNW networks.
