It is possible to make a material absorb more radiation than it has to re-emit, violating the laws of physics in a way that ...

There are fundamentally two ways to generate electricity. The first is based on electromagnetic induction, which remains the backbone of global electricity production today. The second method uses ...

As few as five electrons in a semiconductor can exhibit collective behaviour, forming a “Coulomb liquid”, according to ...

The Moderate Resolution Imaging Spectroradiometer (MODIS) has successfully provided Earth image products for instruments on the Terra and Aqua satellites since 2000 and 2002, respectively. Maintaining ...

Here, an efficient dissipative soliton mode-locked fiber laser in the L-band using nonlinear polarization rotation technology is demonstrated. With a maximum pump power of 495.3 mW and polarization ...

This work addresses the interconnected challenges of climate change, the global energy crisis, and water scarcity. The demand for energy and food, driven by population growth and urbanization, places ...

A 90-minute session of cold exposure increases energy expenditure in people with obesity but also leads to greater food intake and high discomfort, limiting its promise for weight control.
