High color purity 3D printing with nanoparticles

Researchers report on a new method to obtain high color purity 3D objects with the use of a new class of nanoparticles.

Graphene sets sail in microgravity

Researchers demonstrate the laser-propulsion of graphene sails in microgravity. The light sails use a scalable micro-membrane design that minimizes their mass and hence increases their thrust upon light irradiation.

Ultra-long-working-distance spectroscopy with 3D-printed aspherical microlenses

Researchers have designed tiny lenses that can easily be manufactured by laser 3D printing technique on top of various materials, including fragile novel 2D graphene-like materials.

Researchers pave the way to designing omnidirectional invisible materials

Scientists have discovered a new fundamental symmetry in electromagnetism, acoustics and elasticity laws: a temporal supersymmetry.

2D oxide flakes pick up surprise electrical properties

Researchers have found evidence of piezoelectricity in lab-grown, two-dimensional flakes of molybdenum dioxide.

Is dendrite-free lithium sufficient for next-generation Li metal battery technology?

Scientists revealed that eliminating the growth of the dendritic Li structure seemed not to be sufficient to propel the LMB technology from laboratory research to practical applications considering that there are other types of electrochemically generated Li structures besides the dendritic structure.

Shape-shifting carbon fibre could replace mechanical systems for planes and more

Imagine wind turbine blades that change shape to achieve the most efficiency in varying wind speeds, or airplane wings that bend and alter their own form without hydraulic rudders and ailerons.

Artificial intelligence is energy-hungry - new hardware could curb its appetite

Quantum material could offset energy demand of artificial intelligence.
