c, Incoherent two-photon scattering leads to an energy–time entangled pair of photons that are, in general, detuned from the driving field. d, For zero time delay τ, the theoretically predicted second-order correlation function yields g(2)(τ = 0) = 0. For |τ| > 0, ...
aHybrid vehicles offer the promise of higher energy efficiency and reduced emissions when compared with conventional automobiles, but they can also be designed to overcome the range limitations inherent in a purely electric automobile by utilizing two distinct energy sources for propulsion. With hybrid ...
The contemporary drastic increase in the carbon footprint of our planet observed over the last century or so has forcibly yet collectively led us to seeking sustainable alternatives to non-renewable sources of energy used in our everyday lives. Foregoing Internal Combustion Vehicles (ICVs) which ...
Using a consumption-based Multi-Regional Input-Output (MRIO) model, we investigate the distinctive characteristics, self-efficiency or external dependency, of energy demand’s water footprint in China’s two biggest and fastest developing megalopolises. We find that energy demand water footprint in ...
Whereas the US wants to shift away from coal, the EU shifts away from gas due to high natural gas prices in Europe while drastically increasing the feed-ins from renewable energy sources (RES). In some of the European countries constantly growing installation of renewable energy plants is ...
We also highlight potential applications of 2D transistors in conventional micro/nanoelectronics, neuromorphic computing, advanced sensing, data storage and future interconnect technologies. This is a preview of subscription content, access via your institution Access options Access Nature and 54 other ...
EnergyrecoveryWaste-to-EnergyPerformanceestimationA number of waste gasification technologies are currently proposed as an alternative to conventional Waste-to-Energy (WtE) plants. Assessing their potential is made difficult by the scarce operating experience and the fragmentary data available. After ...
Organic agriculture is dependent on fossil fuels, just like conventional agriculture, but this can be reduced by the use of on-farm biomass resources. The energy efficiency and environmental impacts of different alternatives can be assessed by life cycle assessment (LCA), which we have done in th...
Laser-driven ion sources are a rapidly developing technology producing high energy, high peak current beams. Their suitability for applications, such as compact medical accelerators, motivates development of robust acceleration schemes using widely available repetitive ultraintense femtosecond lasers. These ap...
Excess14C production of all known events (Supplementary Fig.3) was (re-)calculated using the above described procedure (Fig.2a). When comparing different events, it is, however, important to note that the same event (in terms of the proton flux and energy distribution) can lead to different...
