The generation of electricity from heat, also known as thermoelectric energy conversion, has proved to be advantageous for various real-world applications. For instance, it proved useful for the generation of energy during space expeditions and military missions in difficult environments, as well as for the recovery of waste heat produced from industrial plants, power stations or even vehicles.
We propose and analyze a universal method to obtain fast charging of a quantum battery by a driven charger system using controlled, pure dephasing of the charger. While the battery displays coherent underdamped oscillations of energy for weak charger dephasing, the quantum Zeno freezing of the charger energy at high dephasing suppresses the rate of transfer of energy to the battery. Choosing an optimum dephasing rate between the regimes leads to a fast charging of the battery. We illustrate our results with the charger and battery modeled by either two-level systems or harmonic oscillators. Apart from the fast charging, the dephasing also renders the charging performance more robust to detuning between the charger, drive, and battery frequencies for the two-level systems case.

The chemical reaction to produce hydrogen from water is several times more effective when using a combination of new materials in three layers, according to researchers at Linköping University in Sweden. Hydrogen produced from water is a promising renewable energy source—especially if the hydrogen is produced using sunlight.
Researchers at Florida State University have created new polymer blends that could make batteries safer and longer-lasting.
Researchers at EPFL and Kyoto University have created a stable hydrogen-rich liquid formed by mixing two simple chemicals. This breakthrough could make hydrogen storage easier, safer, and more efficient at room temperature.
Hydrogen can be the clean fuel of the future, but getting it from the lab to everyday life isn’t simple. Most hydrogen-rich materials are solids at room temperature, or they only become liquids under extreme conditions like high pressure or freezing temperatures.
Even materials such as ammonia borane, a solid, hydrogen-rich compound that can store a lot of hydrogen, are difficult because they release hydrogen only when heated, often producing unwanted byproducts.
The mechanical strength and toughness of engineering materials are often mutually exclusive, posing challenges for material design and selection. To address this, a research team from The Hong Kong Polytechnic University (PolyU) has uncovered an innovative strategy: by simply twisting the layers of 2D materials, they can enhance toughness without compromising material’s strength.
This breakthrough facilitates the design of strong and tough new 2D materials, promoting their broader applications in photonic and electronic devices. The findings have been published in Nature Materials.
While 2D materials often exhibit exceptional strength, they are extremely brittle. Fractures in materials are also typically irreversible. These attributes limit the use of 2D materials in devices that require repeated deformation, such as high-power devices, flexible electronics and wearables.
