The 20th anniversary of the popular consultation that brought independence for Timor-Leste has been a time to celebrate the courage, determination, and persistence of the Timorese people. Despite enduring decades of violence, they never lost their hope for self-determination. Timor-Leste today is a free and sovereign nation.
Phase-change materials (PCMs) are essential modern materials for storing thermal energy in the form of sensible and latent heat, which play important roles in the efficient use of waste heat and solar energy. In the development of PCM technology, many types of materials have been studied, including inorganic salt and salt hydrates and organic matter …
