In this work, we reported experimental investigations on third-order optical properties of aqueous colloidal dispersions of silver nanocubes (Ag-NCs) and Ag-Au hollow nanostructures. The hollow bimetallic are nanoboxes, that were synthesized by galvanic substitution using silver nanocubes as templates, inserting silver with gold in molar ratios of 1.5 and 3.0 mL. This process adjusted tuning the Surface Plasmon Resonance (SPR) compared to the original Ag-NCs nanocubes. Femtosecond Z-scan measurements performed at 1040 nm, 350fs and laser intensities from 99.7 - 279 GW/cm2 shows negative nonlinear refraction for both nanocube and nanoboxes colloids, attributed to hot electron generation. Solvent effects are simultaneously suppressed of the nanostructures. On the other hand, the non-linear absorption observed for bimetallic nanoboxes shows the presence of saturated absorption (SA), but the Ag-NCs do not show a non-linear absorption signal. Therefore, our experimental results provide a reliable reference for the application of these bimetallic nanostructures as active media in nonlinear photonic devices. © 2024, The Authors.

This study examines the efficiency of natural ventilation in maintaining compliant IEQ levels in airtight dwellings. The methodology encompasses a longitudinal study that utilises a combination of low-cost and high-grade sensors in a range of energy-efficient houses in Ireland, to collect measurements of key indoor pollutants and thermal parameters. Results suggest the deficiency of natural ventilation to sustain conforming indoor pollutants levels. The results, presented at the conference, will include the data from ten dwellings, evaluating data trends of the measured parameters, as well as evaluating thermal comfort levels. © 2024 18th Conference of the International Society of Indoor Air Quality and Climate, INDOOR AIR 2024 - Conference program and Proceedings.

Prussian blue (PB) and its analogues (PBAs) are promising coordination polymers (CPs) with an adjustable composition and open framework. Nonetheless, their intrinsic electrochemical activity and electrical conductivity are poor, which hinder their applications in energy conversion and storage. In catalytic applications, metal compounds derived from PB/PBAs have a lot of advantages, such as outstanding stability, selectivity, and electrical conductivity. Furthermore, they can be used as electrode materials for electrochemical energy storage and conversion, while having preferable electronic conductivity, sufficient catalytic active sites, as well as a larger specific surface area and tunable size to achieve an optimized performance. This review summarizes the current achievements of PB/PBAderived metallic nanomaterials, as well as the existing limitations, urgent challenges and future development. © 2022 The Chemical Society of Japan.

Sustainable Lithium Replenishment: A Lifespan Strategy Enabled by Mixed Ionic-Electronic Conductive (MIEC) Li-Mg-Al Alloy Foil

Prelithiation is widely recognized as an effective strategy for prolonging battery cycle life. However, previous prelithiation typically involves adding limited lithium inventory (LiInv) to compensate initial LiInv loss solely, while neglecting the long-term battery cycling. We propose for the first time to increase prelithiation degree and pre-store LiInv as stable LiCx to enable sustainable lithium replenishment which significantly extends battery cycle life and enhances energy density. To achieve this strategy, we developed Li-Mg-Al ultrathin alloy with enhanced mechanical workability for contact prelithiation to replace commercial ultrathin lithium. Li-Mg-Al preserves a mixed ionic-electronic conductive network during delithiation, ensuring efficient transfer of lithium to graphite rather than being randomly distributed on the anode surface. By utilizing a 5-μm 96Li2Mg2Al foil for full lifespan prelithiation, we achieved a high lithium utilization rate of 95.6% and remarkable full-cell capacity retention rate of 99.17% over the first 500 cycles, effectively tripling the battery cycle life. © 2023, The Authors.

Irradiation response of SiOC under simultaneous helium and silicon ion irradiation

SiOC is an amorphous ceramic with superior irradiation stability, making it attractive for applications in high-temperature and high-radiation environments. However, its glassy state stability under the synergistic effects of helium introduction and heavy damage cascades, as expected in a reactor, has not yet been fully assessed. In this study, e-gun evaporated SiOC was simultaneously irradiated using 150 keV helium at a 45-degree incident angle and 1.5 MeV silicon self-ions at a normal incident angle, at room temperature, 300 °C, and 500 °C, respectively. For all irradiation conditions, high-resolution transmission electron microscopy and electron diffraction analysis across different depths of the film did not reveal any crystallization. However, Si-enriched precipitates appeared, with fewer precipitates observed at the highest irradiation temperature. Surface scanning electron microscopy showed periodic patterning on the surface of both room temperature and 300 °C irradiated samples, but not on the 500 °C irradiated sample. The study demonstrates the overall excellent amorphization resistance of SiOC. © 2025

Local step-flow dynamics in thin film growth with desorption

Physical Review materials 2024年第3期8卷 033403-033403页

Headrick Department of Physics and Materials Science Program University of Vermont Burlington Vermont 05405 USA Division of Materials Science and Engineering Boston University Boston Massachusetts 02215 USA X-ray Science Division Argonne National Laboratory Lemont Illinois 60439 USA National Synchrotron Light Source II Brookhaven National Lab Upton New York 11973 USA Department of Physics Boston University Boston Massachusetts 02215 USA

Desorption of deposited species plays a role in determining the evolution of surface morphology during crystal growth when the desorption time constant is short compared with the time to diffuse to a defect site, step edge, or kink. However, experiments to directly test the predictions of these effects are lacking. Novel techniques such as in situ coherent x-ray scattering can provide significant new information. Herein we present x-ray photon correlation spectroscopy (XPCS) measurements during diindenoperylene (DIP) vapor deposition on thermally oxidized silicon surfaces. DIP forms a nearly complete two-dimensional first layer over the range of temperatures studied (40–120∘C), followed by mounded growth during subsequent deposition. Local step flow within mounds was observed, and we find that there was a terrace-length-dependent behavior of the step edge dynamics. This led to unstable growth with rapid roughening (β>0.5) and deviation from a symmetric error-function-like height profile. At high temperatures, the grooves between the mounds tend to close up leading to nearly flat polycrystalline films. Numerical analysis based on a (1+1)-dimensional model suggests that terrace-length dependent desorption of deposited ad-molecules is an essential cause of the step dynamics, and it influences the morphology evolution.
