“…The compressive strength of the PU-based bone binder was higher than pressure (0.1-1.5 MPa) of intervertebral disk. 30 The tensile stress-strain curves of three samples were also characterized and compared as shown in Figure 6c. These samples also exhibited tensile linear elastic deformation in lower strain region than 50%.…”

“…The maximum compressive strength of pure PU, C22/PU, and C22@HAP/PU composite was about 34.3, 5.5, and 1.4 MPa, respectively (Figure 6d). The compressive strength of the PU‐based bone binder was higher than pressure (0.1–1.5 MPa) of intervertebral disk 30 . The tensile stress–strain curves of three samples were also characterized and compared as shown in Figure 6c.…”

Because of the significant advantages of bone adhesives compared with traditional mechanical fixation, many scholars have studied polyurethane bone adhesives. However, polyurethane will release a lot of heat in the reaction process, producing high temperature. The high temperature does not only easily cause a human discomfort but also will destroy the tissue structure of human. In this paper, a new polyurethane composite based on phase transition materials and hydroxyapatite is prepared to reduce released heat for application in bone binder. The mechanical properties, adhesive strength, and released heat‐induced temperature of polyurethane composite are investigated in detail. It exhibits good viscoelastic performance with a large elastic deformation (>30%) and good adhesive strength (>0.2 MPa). Furthermore, the released heat of polyurethane composite is effectively reduced, in which the temperature drastically decreases from 110.4 to 41.8°C. The work does not only confirm formation of high‐performance bone binder but also provides a new method to reduce released heat of polyurethane for various applications.

“…PET scan produces detailed threedimensional images to determine blood flow, oxygen levels, and metabolic variations. PET scanner detects the radiations returned by injected radiotracer inside the body [88]. It provides a detailed overview of metabolic changes appearing at the cellular level in tissue or an organ and is thus considered superior to CT scans and MRI [89].…”

The strong association between hearing loss and cognitive decline has developed into a major health challenge that calls for early detection, diagnosis and prevention. Hearing loss usually results in severe health implications that include loss of mobility, communication problems and cognitive decline. This study provides an overview of the effects of hearing loss on cognition and progressive neurological disorders with a discussion on the future scope of microwave portable technologies in care homes arrangement. Moreover, the efficacy of hearing aids in reversing cognitive decline and dementia has been investigated. The interconnection between hearing loss, cognitive load and neurodegeneration is also explored. Furthermore, this study looks into the prospects of using portable microwave sensors for the detection and monitoring of cognitive load. For early detection of dementia, this study proposes the integration of microwave sensors with hearing aid devices. Implications and design challenges of portable antenna systems for neurodegeneration detection have also been considered. Future improvement areas regarding robust analysis and diagnosis, system accuracy and security, user-centricity and device privacy for a broader clinical implementation are also discussed.
