Summary: The effect of the diameter of PA11 NFs on their structures and properties was investigated. Aligned PA11 NFs with diameters ranging from 109 to 462 nm were prepared and characterized. All prepared NFs had similar crystallinities and crystallite sizes, but the orientation of the crystals was disrupted in NFs with diameters less than 200 nm. The NFs with a diameter of approximately 300 nm had the most highly oriented crystals and exhibited the highest mechanical strength and piezoelectric response.

Summary: Health monitoring and its associated technologies have become increasingly important. The electrocardiogram (ECG) has been widely used for assessing and diagnosing cardiovascular diseases (CVDs). With the growing literature on ECG monitoring devices, researchers and healthcare professionals face challenges in selecting and evaluating systems that meet their needs and monitoring standards. This paper presents a comprehensive ECG monitoring system that captures and displays patients' heart signals, heart rate, blood oxygen levels, and body temperature. The system utilizes an OLED display, an Android application, and MATLAB for data presentation. Internet of Things (IoT) approaches are advantageous in improving heart disease patient care and alerting healthcare services based on patients' physical condition. Additionally, a web server is included for monitoring patients' status via WiFi. The prototype, compliant with safety regulations and medical equipment design, demonstrated excellent accuracy of 99.56% compared to a commercially available device.

Summary: A novel solid-liquid two-phase precipitation method was proposed for the synthesis of high-quality fullerene nanowires, showing a narrower diameter distribution compared to the widely-used liquid-liquid interfacial precipitation method. The gradual melting of the solid-phase C-60 in m-xylene is believed to provide a more stable interface for crystal growth.
