Abstract The effect of x = Ce/(Hf+Ce) (0.15-0.25) on dielectric, ferroelectric, and piezoelectric properties was investigated together with the crystal structure for 500 nm-thick xCeO2-(1-x) HfO2 films. The films were deposited on (111) (indium tin oxide, ITO)//(111) (yttrium-stabilized zirconia, YSZ) substrates using…
The catalytic valorization of biomass-derived 5-hydroxymethylfurfural (HMF) provides an important route toward sustainable chemical production. Herein, we report a bimetallic Pt1Au1 catalyst supported on Vulcan XC-72R carbon (Pt1Au1/XC) that enables efficient aerobic oxidation of HMF to FDCA using NaHCO3 as a weak bas…
This chapter describes the development of a top-loading sample probe for neutron scattering experiments operating in a cryogen-free He-3 cryostat with high-voltage capability. The probe supports DC biases up to 10 kV while maintaining stable operation at temperatures as low as 400 mK. Parasitic heat loads are minimize…

Selective laser flash sintering (SLFS) is emerging as a promising route for binder-free additive manufacturing of ceramics. Monitoring local temperatures during SLFS allows correlations between processing variables and the temperatures required for SLFS. This study demonstrates a visible-near infrared (vis-NIR) imagin…
Abstract Super duplex stainless steels (SDSSs) are well known for their good mechanical properties and corrosion resistance inherited from the dual-phase microstructure with equivalent proportion of ferrite and austenite. The development of additive manufacturing has given rise to the use of more diversified material…
Abstract Polymer-based dielectric composites are pivotal for advanced pulsed power and power electronics, yet synergistically enhancing dielectric constant and breakdown strength remains a formidable challenge. Herein, we report a controllable layer-by-layer spray assembly strategy to fabricate ordered multilayer poly…
Python code and supporting files used to evaluate the explicit special-function formulas and generate the numerical illustration in the manuscript “Explicit Cartesian coordinates for three-dimensional clothoids”. The Cartesian coordinates are evaluated directly from the closed formulas; no numerical integration of the…
Abstract Protein-based recovery, detection, and separation of rare earth elements (REs) have accelerated since the discovery of the lanmodulin (LanM) proteins. While exceptional at total RE recovery, prior proteins, like most ligands, exhibited limited ability to differentiate REs, whether in detection or separations.…
Abstract 19F nuclear magnetic resonance (NMR) spectroscopy is widely used for structural elucidation of fluorinated molecules, but reliable prediction of 19F chemical shifts remains challenging because quantum-chemical calculations are computationally demanding and their accuracy can vary across diverse molecular envi…
Accurately predicting the acoustic properties of noise-reduction materials in real-world, flow-exposed environments remains a significant challenge in engineering. Classical models of microslit panels are unsuited for grazing flow conditions due to complex, nonlinear flow-acoustic interactions. To overcome this challe…

Environmental context Microplastics are widespread aquatic contaminants that can alter the environmental behavior of co-occurring pollutants. This study shows that polystyrene microplastics substantially modify silver nanoparticle bioaccumulation in Daphnia magna, increasing waterborne uptake, accelerating elimination…
This paper studies a deliberately closed testbed for scientific relation discovery. Classical mechanics is encoded as a typed graph with 159 quantity nodes, 131 equation nodes, and 15 law nodes, and an operator-conditioned graph attention network is trained to infer hidden quantities from partial observations. The tra…
Abstract Surface texturing can significantly enhance the tribological performance of materials. In this study, a novel moon-shaped surface texture was designed and optimized via computational fluid dynamics (CFD) simulations. The optimal geometric parameters were identified as R 1 = 100 μm, R 2 / R 1 = 1.5, and the co…

DRAM电容介质在1z nm节点以下面临漏电×EOT缩放的硬约束(IMW 2020),产业30年以掺杂钉扎四方相稳定高k介质(ZrO₂/HfO₂基)为应对——但这一长期实践缺少统一的判据语言。本文用场域理论框架(材料=密度聚类场ρ=m·p;相变候选=失效线R'=1平衡区;剪切软模=相变活性签名)对DRAM高k介质给出可计算判据坐标。核心结果:①软模判据产业命中验证——高k介质家族6材料对照中,唯一具有反铁电(AFE)相变活性的ZrO₂恰好是唯一落软模区(C44=20.3 GPa≤阈值22.7)的Hf/Zr氧化物,其余产业稳定介质全部不软(正1/1负4/4);②二维判据空间——软模轴(相变活性/0K亚稳)×带隙轴(漏电墙),ZrO₂…
Focused ultrasound (FUS) in combination with micro- or nanobubbles is a promising strategy for transiently and non-invasively opening the blood-brain barrier (BBB) to enable targeted drug delivery to the brain. Here, we report a FUS-responsive delivery system using bi-layer nanobubbles (NBs) loaded with small molecule…
Green synthesized zero valent iron nanoparticles (nZVI) are promoted as environmentally benign alternatives to chemically synthesized ones. Simulation models are used to predict nZVI transport and transformation during environmental remediation. The objective of this study was to simulate the environmental fate and tr…
