Superlubricity and Corrosion Inhibition Properties of Solvate Ionic Liquids in Hybrid Carbon Fiber Reinforced Plastic–Steel Interfaces

Advanced Engineering Materials, EarlyView.
Solvate ionic liquids lubrication reduced the coefficient of friction by ∼60% compared to dry sliding, reaching steady‐state values as low as 0.04–0.05. Corrosion weight‐loss measurements in 1 M HCl further demonstrated significant inhibition behavior, with only 100 ppm of [Li(G3)][TFSI] (∼68.5 μL/L) reducing corrosion‐product weight loss by 63 ...

Enhanced Ultrasound Transmission Through Aberration Layers Using Space‐Coiling Acoustic Metamaterials

Advanced Engineering Materials, EarlyView.
Enhancing ultrasound transmission through an aberration layer exhibiting mismatched impedance with the surrounding medium possesses great implications in imaging and treatment. In this study, we show that a space‐coiling acoustic metamaterial with judiciously tailored structural profile can help improve impedance matching.

Printed Integrated Logic Circuits Based on Chitosan‐Gated Organic Transistors for Future Edible Systems

Advanced Functional Materials, EarlyView.
Edible electronics needs integrated logic circuits for computation and control. This work presents a potentially edible printed chitosan‐gated transistor with a design optimized for integration in circuits. Its implementation in integrated logic gates and circuits operating at low voltage (0.7 V) is demonstrated, as well as the compatibility with an ...

Intermediate Resistive State in Wafer‐Scale Vertical MoS2 Memristors Through Lateral Silver Filament Growth for Artificial Synapse Applications

Advanced Functional Materials, EarlyView.
In MOCVD MoS2 memristors, a current compliance‐regulated Ag filament mechanism is revealed. The filament ruptures spontaneously during volatile switching, while subsequent growth proceeds vertically through the MoS2 layers and then laterally along the van der Waals gaps during nonvolatile switching.

The Changes of Amplitude of Low-Frequency Fluctuation in the Acute Phase Patients with Concussion

Asian Case Reports in Emergency Medicine, 2015
目的：探讨伴有认知功能改变的脑震荡急性期患者功能磁共振低频振幅(ALFF)变化与其临床症状之间的关系。方法：采用静息态血氧水平依赖功能磁共振成像(BOLD-fMRI)及其低频振幅(ALFF)计算法，对急性期伴有认知功能改变的脑震荡患者在静息状态下获得相关资料进行分析。研究组为脑震荡成年患者10人；对照组为健康成年志愿者10人。研究组10人均在伤后72小时内完成BOLD-fMRI检查。两组均采用GE公司制造MR750 3.0T磁共振成像系统，在静息态下采集BOLD-fMRI成像数据。结果：与对照组比较，研究组在边缘叶、扣带回、楔前叶、左侧颞上回、颞中回、右侧额上回等脑区表现为ALFF值升高，临床上出现记忆能力、语言表达、情绪反应等认知功能改变。结论：脑震荡急性期患者认知功能异常，可能与边缘叶、扣带回 ...
