Refractory nanocomposite films are employed to prevent wear of mechanical components under harsh conditions; however, they are traditionally manufactured at elevated temperatures, causing undesirable microstructural transformations. This study presents a novel electric field- and contact stress-activated sintering process for fabricating tungsten carbide (WC-Co) films at low temperatures (100 °C). In this process, nanoparticle-containing "inks" are supplied to stressed sliding/rolling...

CONCLUSION: Our study revealed that approximately one in six scans was rejected due to low quality, with higher rejection rates in eyes with severe visual impairment. As scan quality can bias quantitative outcomes and artificial intelligence applications, these findings emphasize the unmet need for standardized OCT practices tailored to NMOSD and other conditions involving severe visual impairment.

BACKGROUND: American Indian and Alaska Native (AI/AN) peoples bear the highest U.S. burden of substance-use disorder (SUD) and drug-overdose mortality. Mechanistic evidence linking community-defined cultural protective factors to neurobehavioral pathways of SUD risk is virtually absent. Most AI/AN health studies are descriptive and rarely integrate neuroscience.

Accurate determination of water-oil ratios in multiphase systems faces persistent challenges in achieving non-invasive global measurements due to the intrinsic limitations of conventional detection modalities. We develop a terahertz optoacoustic method that enables real-time quantification of water-oil ratios across the full operational range (0-100 %) in both static and dynamic regimes. For quiescent systems, the technique achieves spatially resolved mapping of phase distributions through...

CONCLUSION: Though rare, healthcare providers should maintain an index of suspicion for Fusarium infections in recipients of cellular therapies with risk factors.
