A thermal diode based on nanoscale thermal radiation

Researchers explore rectification in the near-field, where heat fluxes are much larger than those in the far-field and can exceed the blackbody limit of far-field thermal radiation, and demonstrate that rectification coefficients between VO2 and doped Si can exceed 50% in the near-field for moderate temperature differences.

Could a particle accelerator using laser-driven implosion become a reality?

Scientists have discovered a novel particle acceleration mechanism called 'Micro-bubble implosion,' in which super-high energy hydrogen ions (relativistic protons) are emitted at the moment when bubbles shrink to atomic size through the irradiation of hydrides with micron-sized spherical bubbles by ultraintense laser pulses.

Scientists crack code to cheap, small carbon nanotubes

Imagine a box you plug into the wall that cleans your toxic air and pays you cash. That's essentially what researchers produced after discovering the blueprint for turning the carbon dioxide into carbon nanotubes with small diameters.

Supertetrahedra Lego for future batteries

New sodium-based all-solid-state batteries could enable future energy storage devices using only the easy-to-access, cheap and earth abundant elements sodium, silicon and phosphorous (Na, Si and P). By shaping them into sodium phosphidosilicates containing large supertetrahedral entities, scientists generated solid electrolytes with very high ionic conductivity.

Universal pH regulated assembly of DNA nanostructures

Scientists have introduced a new strategy for control through altering pH value. It is based on ethylenediamine, which only supports the assembly of DNA components in a neutral to acidic environment - independent of the base sequences and without metal ions.
