The past few decades have seen an escalation of power densities in electronic devices, and in particular in microprocessor chips. Together with the continuing trend of reduction in device dimensions this has led to dramatic increase in the thermal issues…
In traditional aircraft design, airframes and engines are designed separately and bolted together. This leads to inefficiencies due to additional drag. The approach also leads to propulsive inefficiencies via non-distributed propulsion. Hovering and VTOL requirements introduce even more complexity, size…
The civil global aviation market has experienced considerable economic growth in recent years and will keep increasing. It is estimated that around 1300 new international airports will be required, and the commercial aircraft fleet will double by 2050, with a…
The control of electric currents in solids is at the origin of modern electronics which has revolutionised our daily life. The diode and the transistor introduced by Braun and Bardeen and Brattain are undoubtedly the corner stones of modern information…
The amount of electricity consumed worldwide grows by the year, and so does the demand for energy storage solutions since many devices often operate in autonomous mode. Rechargeable lithium-ion batteries have been workhorse of the consumer electronics market including portable…
The rapid increase in global energy consumption and the environmental impact of traditional energy resources pose serious challenges to human health, energy security, and the environment; and reveal a growing need to develop new types of clean and sustainable energy…
Traditional missiles powered by rocket motors typically carry both fuel and oxidizer. An air-breathing ramjet missile can dispense with the separate oxidizer payload, reducing the size of a propulsion package. Thanks to ramjets, smaller missiles use that space for other…
Vehicle electrification is one of the greatest developments in the automotive sector. Increasing apprehension about environmental fortification has prompted the research that greatly propelled the electric mobility around the globe. By 2025, 7 million electric vehicles are projected to be…
Global aviation fuel market was valued at US$178.560 billion in 2019 and is expected to grow at a CAGR of 6.00% to reach a total market size of US$253.261 billion in 2025. Booming travel and tourism industry is one of…
Zero-point energy is the energy that remains when all other energy is removed from a system. Zero-point energy is the lowest energy that a given quantum mechanical system can have (i.e., the ground state of the system). In quantum field…
