Researchers solve major challenge in mass production of low-cost solar cells

Spray coating could make perovskite an inexpensive alternative to silicon for solar panels.

Beyond conventional solution-process for 2-D heterostructure

Researchers demonstrated a facile wet-chemical method to directly grow organic-inorganic hybrid perovskite nanocrystals on surfaces of dispersible MoS2 nanosheets.

Scientists print sensors on gummi candy

Printing microelectrode arrays on gelatin and other soft materials could pave the way for new medical diagnostics tools.

Thermal radiation from nanoparticles

Scientists have succeeded in performing time-resolved measurements of the internal energy distribution of stored clusters. The clusters investigated consisted of four cobalt atoms and an additional electron.

When fluid flows almost as fast as light - with quantum rotation

Quark-gluon plasma is formed as a result of high energy collisions of heavy ions. After a collision, for a dozen or so yoctoseconds, this most perfect of all known fluids undergoes rapid hydrodynamic expansion with velocities close to the velocity of light.

Adaptive 3D printing for the fabrication of multifunctional devices on moving freeform surfaces

Researchers report a new method for, termed adaptive 3D printing, for the fabrication of multifunctional devices on moving freeform surfaces.

Graphene assembled film shows higher thermal conductivity than graphite film

Researchers have developed a graphene assembled film that has over 60 percent higher thermal conductivity than graphite film - despite the fact that graphite simply consists of many layers of graphene.

Ratchet up the pressure: Molecular machine exploits motion in a single direction

Researchers invent ratchet-like molecular machine, where a chemical reaction is coupled with unidirectional movement, as a possible component for molecular motors.
