Scientists demonstrate enhanced hydrogen production from sunlight-assisted water splitting using a polydopamine-coated zinc sulfide nanorod catalyst.

Researchers develop, tests nano-carrier as potential treatment for glioblastomas.

In another step towards engineered living materials, researchers combined living bacteria and 3D-printed materials to grow bionic mineralized composites with ordered microstructures. It provides an example of harnessing living bacteria to design self-growing materials and opens the door for a new class of engineering materials that can self-grow like living creatures. This manufacturing strategy can be easily extended by selectively controlling the activity of living organisms to synthesize unprecedented structural composites with ordered, hierarchical, and gradient microstructures.

Scientists are harnessing the power of swirling cellular proteins to create self-propelling fluids.

Researchers report hyperspectral optical images, generated by a nano-Raman spectroscope, of the crystal superlattice in reconstructed (low-angle) twisted bilayer graphene.

New storage and information technology requires new higher performance materials. One of these materials is yttrium iron garnet, which has special magnetic properties. Thanks to a new process, it can now be transferred to any material.

Terahertz spectroscopy penetrates graphene films allowing scientists to make detailed maps of their electrical quality, without damaging or contaminating the material.

According to a new study, Earth, Venus and Mars were created from small dust particles containing ice and carbon. The discovery opens up the possibility that the Milky Way may be filled with aquatic planets.

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.
