    Development of Self-Healing Thermoplastic Composites With Reactive Thermoplastic Agent-Filled Macrocapsules
    (Wiley, 2025-05) Şahin, Eslem; Boztoprak, Yalçın; Yazıcı, Murat; 414011
    Self-healing materials, which introduce a new approach to innovative materials, can aid in the repair of polymers and composites, leading to the development of more durable and reliable products. In polymer matrix composites, healing micro- or macrocracks helps to eliminate structural defects. A reactive healing agent and curing agent distributed within the thermoplastic matrix can react at the crack site, providing repair without external intervention. Acrylic resin and polypropylene were selected for this study to evaluate the potential of healing in industrial thermoplastics. Capsules filled with a reactive agent containing 3% by weight diethylenetriamine (DETA) were embedded in the matrix. When damaged, these capsules broke, and the liquid agents seeped into the cracks through the filling voids. The reaction released immediate heat, initiated curing, and filled the damaged area. Complete curing occurred after 8 h. The energy absorption of specimens in both damaged and undamaged states was observed through compression testing. The heat generated by the agents flowing from the capsules during the compression test was monitored using a thermal camera. This study offers a new perspective on using reactive thermoplastic resins to develop self-healing composite materials.

    Patients' Expectations and Satisfaction Regarding to the Protection of Their Individual Dignity After Surgery: A Cross-Sectional Study
    (Wiley, 2025-05) Güneş, Ayşegül; Eren, Esra; Tekin, Yasemin Eda; 292320
    This study aimed to determine patients' expectations and satisfaction regarding protecting their dignity after surgery. This descriptive, cross-sectional study was conducted with 385 patients between December 2024 and February 2025. Research data was collected using the "Inpatient Dignity Scale" and socio-demographic information form. It was determined that the patient's dignity scale expectation and satisfaction total scores were 72.85 +/- 4.509 and 85.03 +/- 8.011. Accordingly, the expectation scores of the young, those with higher education levels, those whose income is lower than their expenses, those who have had surgery before, those who can perform activities of daily living those who can do it with assistance, those who can connect the head and neck are significantly stronger (p < 0.05). The satisfaction scores of the married, those with the highest and lowest education levels, those whose income is lower than their expenses, those who have had a longer hospital stay after surgery, and those who have had head and neck surgery are higher (p < 0.05). New studies should be conducted in surgical units where nursing activities to protect patient dignity are planned, and their results are evaluated.
