AI Article Synopsis
- The article explores the effectiveness of pulse ultrasonic cure monitoring for carbon fiber reinforced plastics used in the pultrusion process, focusing on profiles with small cross sections.
- Ultrasonic transducers are attached to the pultrusion tool to measure the time-of-flight and amplitude of ultrasound waves, helping to determine the curing state of the epoxy matrix.
- The findings indicate that while the technique can be applied to thin cross sections, there are notable challenges encountered during the actual pultrusion process.
Article Abstract
This article discusses the results of a series of experiments on pulse ultrasonic cure monitoring of carbon fiber reinforced plastics applied to the pultrusion process. The aim of this study is to validate the hypothesis that pulse ultrasonic cure monitoring can be applied (a) for profiles having small cross sections such as 7 mm × 0.5 m m and (b) within the environment of the pultrusion process. Ultrasonic transducers are adhesively bonded to the pultrusion tool as actuators and sensors. The time-of-flight and the amplitude of an ultrasonic wave are analyzed to deduce the current curing state of the epoxy matrix. The experimental results show that ultrasonic cure monitoring is indeed applicable even to very thin cross sections. However, significant challenges can be reported when the techniques are used during the pultrusion process.

Traumatic brain injury (TBI) induces neurogenerative disorders affecting severely daily human activities and early diagnosis is a critical requirement for prevention and cure. Here, we induced TBI formation in the Zebra fish, a model organism, by both mechanical (ultrasonic cleaner generated convulsive shock, UGCS) and chemical (pentylenetetrazol, PTZ) methods. The TBI induced cellular and neuronal changes are monitored by measuring the activities of the indicator biomarkers viz.

The purpose of this study was to evaluate the impact of various mechanical surface treatments on the surface roughness and microtensile bond strength (µTBS) of aged composite resin cores bonded to CAD/CAM restorations. Composite resin specimens (Filtek Z350 XT, 3M-ESPE/Solventum) were thermally aged and subsequently divided into four groups (n = 36) according to surface treatments: UI-cleaning with ultrasonic diamond tip; AO-sandblasting with 50 µm AlO; DB-cleaning with diamond burs; and CG-positive control group, without aging or surface treatment. Surface roughness was assessed using a profilometer and interferometer, with measurements taken on both sides of each specimen (n = 12).

Background: The Woven EndoBridge (WEB) is a treatment modality available for the treatment of intracranial aneurysms, specifically beneficial in wide-necked bifurcation aneurysms. Conventional sizing methods rely on the manipulation of aneurysm width and height measurements. This results in frequent need for re-sizing after initial WEB insertion attempts.

Research into particulate polymer composites is of significant interest due to their potential for enhancing material properties, such as strength, thermal stability, and conductivity while maintaining low weight and cost. Among the various techniques for preparing particle-based composites, ultrasonic wave stimulation is one of the principal laboratory-scale methods for enhancing the dispersion of the discontinuous phase. Nevertheless, there is a scarcity of empirical evidence to substantiate the impact of stimulating materials with natural sound frequencies within the acoustic spectrum, ranging from 20 Hz to 20 kHz, during their formation process.
