Skoltech scientists discovered over 200 carbon-oxygen compounds with high energy potential, some rivaling TNT, offering new insights into non-nitrogen-based explosives and applications in energy, space, and chemical research. Skoltech researchers have conducted a theoretical study exploring a wid
A team of materials scientists, chemical engineers, and environmental scientists affiliated with a host of institutions in China has developed a redox flow battery (RFB) with 87.9% energy efficiency, which can also last for 850 cycles. In their project, published in the journal Nature Communications, the group developed a new kind of catalytic electrode to improve the efficiency of the battery.

Fluids play a crucial role in industrial processes like cooling, heating, and mixing. Traditionally, most industries would utilize Newtonian fluids—which have a constant viscosity—for such processes. However, many are now adopting viscoelastic fluids, which can behave as both liquids and elastic materials.
These fluids can suppress turbulence in simple flows like straight pipes or channels, leading to reduced wall friction. This “drag reduction effect” has attracted significant interest due to its potential to enhance energy efficiency.
To advance the industrial applications of such fluids, it is critical to understand how these fluids interact with turbulence.
For the first time, scientists have captured a stunning image of plasma’s “spaghetti-like” instability, revealing a phenomenon that could reshape our understanding of energy and fusion.
A team of international researchers has developed a groundbreaking class of mechanical metamaterials capable of storing and releasing elastic energy at unprecedented levels. By cleverly twisting rods into a helical shape and integrating them into a new metamaterial structure, they’ve overcome tra
UC Berkeley engineers built the smallest untethered UAV ever at just 9.4 mm across by utilizing magnetic fields as a power source.
A trio of US researchers claim to have successfully tested predictions that it’s possible to harvest clean energy from the natural rhythms and processes of our planet, generating electricity as Earth rotates through its own magnetic field.
Though the voltage they produced was tiny, the possibility could give rise to a new way to generate electricity from our planet’s dynamics, alongside tidal, solar, wind, and geothermal power production.
In 2016, Princeton astrophysicist Christopher Chyba and JPL planetary scientist Kevin Hand challenged their own proof that such a feat ought to be impossible. The researchers have now uncovered empirical evidence that their proof-breaking idea may actually work, as long as the shape and properties of the conducting material in their method are set to very specific requirements.
A millimetre-scale bioresorbable optoelectronic system with an onboard power supply and a wireless, optical control mechanism is developed for general applications in electrotherapy and specific uses in temporary cardiac pacing.
The word “abated” is the focus of much debate in the context of carbon dioxide emissions. World leaders have this year been underlining their commitment to phase out the use of unabated fossil fuels: that is, where emissions from their combustion are not mitigated through offsets or carbon capture technologies.
The final text of the COP28 statement called for “abatement, and removal technologies, such as carbon capture and utilisation and storage, particularly in hard-to-abate sectors.” Meanwhile the G7 group of nations last year called for “a global effort to accelerate the phase-out of unabated fossil fuels to achieve net zero in energy systems by 2050.” Such commitments are important in the race to decarbonize traditional energy sources, but they raise an important question: How exactly should we define “abated” emissions?
Currently, there is no widespread agreement on the answer, specifically on how much carbon dioxide should be removed for emissions to be classed as “abated”. Some scientists argue this lack of definition risks hampering decarbonization efforts. “The term ‘unabated’, if left unchecked and poorly defined, could leave the interpretation of the commitment wide open,” said a 2023 working paper by a group of scientists at Columbia University cited by Reuters.
