Fight to the top: Silver and gold compete for the surface of a bimetallic solid

It's the classic plot of a buddy movie. Two struggling bodies team up to drive the plot and do good together. That same idea, when it comes to metals, could help scientists solve a big problem: the amount of energy consumed by making chemicals.

X-ray microscope optics resolve 50-nm features while eliminating chromatic aberrations

An optical system for a full-field X-ray microscope eliminates chromatic aberrations that previously limited resolution capabilities.

Solar cells with nanostripes

On their search for underlying physical mechanisms, researchers have now detected strips of nanostructures with alternating directions of polarization in the perovskite layers.

New porous solids may lead to better drugs

Decades-long research culminates in a new way of creating left- and right-handed molecules.

Zapping bacteria with sanitizers made of paper (w/video)

Researchers have invented an inexpensive, effective way to kill bacteria and sanitize surfaces with devices made of paper.

Saving energy through light control

New materials can reduce energy consumption with the flip of a switch.

Teaching perovskites to swim

By carefully growing an ultrathin layer of metal oxide on a carbon coating, researchers made a perovskite device that worked even after dousing the device with a stream of water.

Stenciling with atoms in 2-dimensional materials possible

In new research, material scientists report two discoveries that will provide a simple and effective way to 'stencil' high-quality 2D materials in precise locations and overcome a barrier to their use in next-generation electronics.

New coating surface for superior rust resistance with 'colorless' color

Electrophoretic deposition coats metal with non-ionic polymer.

Erasable ink for 3D nano-printing

Scientists have developed a method to erase the ink used for 3D printing. In this way, the small structures of up to 100 nm in size can be erased and rewritten repeatedly.

Formamidinium perovskite nanocrystals: Bright, cheap and stable

Researchers report facile and rapid room temperature synthesis of cubic and platelet-like colloidal nanocrystals of Formamidinium Lead Halide Perovskite by ligand-assisted re-precipitation method.

Graphene-based contact lens sensor for diabetic and glaucoma diagnosis

A recent study proposes the possibility of in situ human health monitoring simply by wearing a contact lens with built-in wireless smart sensors.

Inkjet-printed batteries bring us closer to smart objects

A rechargeable power source printed onto normal paper using a standard inkjet printer could pave a new way for a wide range of 'smart' objects.
