Paper industry wastewater recycling is among the most energy-intensive chemical processes in the world. Researchers have found a method to engineer membranes made from graphene oxide that allow water to get through it much faster than through conventional membranes and, in the process, can save the paper industry more than 30% in energy costs of water separation.

Engineers describe a flexible film using a quasi-one-dimensional nanomaterial filler that combines excellent electromagnetic shielding with ease of manufacture.

Large galaxies are known to strip the gas that occupies the space between the stars of smaller satellite galaxies. Astronomers have discovered that these small satellite galaxies also contain less 'molecular' gas at their centres.

Researchers harness the power of living organisms to make materials that are strong, tolerant and resilient.

In solid-state physics the precise interactions of electrons are analyzed in meticulous detective work to ultimately gain a better understanding of fundamental physical phenomena.

Researchers have developed a new approach with a cost-effective and easy electrode fabrication that is completely ITO-free.

The design may enable miniature zoom lenses for drones, cellphones, or night-vision goggles.

A promising technology under development for negative emissions technologies is carbon capture using a material called a MOF, or metal-organic framework.

Synthetic biologists have developed a design-driven process that uses parts from a very different kind of toolkit to build complex genetic circuits for cellular engineering.

Scientists have made a surprising discovery: an exotic metal made of cerium, bismuth and palladium was examined and a giant Hall effect was found to be produced by the material, in the total absence of any magnetic field.

Scientists studied the arrival directions of astrophysical neutrinos with energies more than a trillion electronvolts (TeV) and came to an unexpected conclusion: all of them are born near black holes in the centers of distant active galaxies powerful radio sources. Previously, only neutrinos with the highest energies were assumed to be obtained in sources of this class.

Science and policy need to incorporate diversity and complexity of the world when thinking about a sustainable future.

Physicists have proposed an innovative new data storage medium. The technique is based on specific properties of antiferromagnetic materials that had previously resisted experimental examination.

Regeneration of muscle tissue was achieved by combining direct cell reprogramming with natural-synthetic hybrid scaffold as structural support.

A silicone membrane for wearable devices is more comfortable and breathable thanks to better-sized pores made with the help of citric acid crystals.

Scientists have demonstrated the generation of tunable and coherent frequency combs in a pair of hybridized optical microresonators.

A new pilot line demonstrates the efficient, design-driven manufacture of cellulose-based electrical insulation components with 3D printing.

Using nitride-based materials, researchers created a material structure that simultaneously exhibits superconductivity - in which electrical resistance vanishes completely - and the quantum Hall effect, which produces resistance with extreme precision when a magnetic field is applied.

Researchers have developed a material and fabrication process that can rapidly make these devices stretchier, more durable, and closer to being ready for mass manufacturing.

A new artificial membrane helps researchers understand proteins in human cell membranes. The membrane rim is made of a detergent, with a center made of lipid molecules found in biological membranes, including cholesterol.
