Generally the transition will be from one of the first two fundamental states of matter - solid and liquid - to the other. </p> University of Calabria/ Royallite Global UK en-US Journal of Phase Change Materials 2788-7170 https://j-pcm.org/index.php/jpcm/article/view/32 <p>Bone healing is a synergistic treatment process associated with osteogenic cells, cell signaling, and blood vascularization. Composite scaffolds made of bioactive materials have been systematically utilized for tissue reconstruction. The utilization of composite materials not only provides the required mechanical stability to the scaffold but also improves its biological activity. For the best clinical outcome, a scaffold should have good bio-responsive functions such as good biodegradability, high bioactivity, and excellent osteoconductivity. The development of bioactive materials capable of adapting to <em>in vivo</em> tissue functions in response to dynamic physiological changes and bio-mechanical activities is an important challenge in bone tissue engineering. The current situation of frequent medical prosthetic failure is primarily associated with deficiencies in materials performance due to mismatched tissue morphology, inert bioactivity, and mechanical failure. In fact, optimal clinical grade tissue engineering materials remain elusive. Here, we present a brief review of the current status of composite materials, especially the composites made of bioactive polymers such as naturally derived collagen, silk fibrin, and chitosan, and their usage in bone-tissue engineering. Critical aspects such as composition, fabrication technique, and mechanical properties of composite materials in the development of efficient scaffolds for bone regeneration have been discussed.</p> Umapada Pal Copyright (c) 2023 Umapada Pal https://creativecommons.org/licenses/by/4.0 2023-06-02 2023-06-02 3 1 10.58256/jpcm.v3i1.32 https://j-pcm.org/index.php/jpcm/article/view/31 <p>Converting solar energy into a clean, practical alternative power source will require highly efficient and inexpensive devices that generate electrical power from solar irradiation. It attracts attention of researchers working on various photovoltaic technologies. Different generations of solar cell have been developed.</p> <p>To achieve this goal of high efficient economically viable next generation solar cell, organometal-trihalide perovskite semiconductors are one of the technologically important materials acts as active layer in solar cell.. The absorption of light by the perovskite layer on solar cell generates a greater no of electron and hole pairs. On optimizing the device design and film-deposition parameters and techniques, researchers expect perovskite thin film solar cells offer more advantages than other conventional thin film photovoltaic cells in the future.</p> Ushasi Dutta Copyright (c) 2023 Ushasi Dutta https://creativecommons.org/licenses/by/4.0 2023-07-06 2023-07-06 3 1 10.58256/jpcm.v3i1.31
