Lithium heat pipe has broad applications in cooled reactors and hypersonic vehicles due to its ultra-high working temperature which is around 1700 K. In this paper, a lithium based experimental facility been designed test the transfer performance of pipe. A simplified mathematical model implemented into CFD approach, used verify design facility. Results showed that approach good agreements with...

The Obama administration in the USA, the Cameron government in the UK, and other donors talk almost daily about developing countries owning and directing their health programmes. But are donors ready to do so? And what would that look like? In most cases, donors control exactly how their money will be spent. The donor defi nes the priorities. We have some ideas to change the dynamic, from the b...

Carbon dots (CDs), a nanomaterial synthesized from organic precursors rich in carbon content with excellent fluorescent property, are high demand for many purposes, including sensing and biosensing applications. This research focused on preparing CDs natural abundant waste, palm kernel shells (PKS) obtained oil biomass, aiming Ethylenediamine L-phenylalanine doped were produced via the hydrothe...

Solar energy’s most promising application is in water heating, followed by other solar thermal applications. In this investigation, a novel method of incorporating phase-change material (PCM) between the annulus space an evacuated tube and aluminum finned heat pipe employed. During day time, PCM stores excess amount releases it order to flowing during high-demand/insufficient radiation. This st...
