This first version of a new layered perovskite solar cell already achieves an efficiency of more than 20 percent, rivaling many commercial solar cells. Flexible and easy to make, it can produce more than half a volt of electricity....
Researchers from Brown University have found a new method for making ultrathin metal-oxide sheets containing intricate wrinkle and crumple patterns. In a study published in the journal ACS Nano, the researchers show that the textured metal-oxide films have better...
Dental follicle stem cells cultured on different scaffolds for 10, 20 and 30 days. Alizarin red stain was used to detect stem cell mineralization (the red indicates the bone mineralization). Bone differentiation rate of cells on the cellulose-nanocrystal scaffold...
Nanostructure made of gold. Credit: Vienna University of Technology It is the philosopher's stone of nanotechnology: Using a technological trick, scientists at TU Wien have succeeded in creating nanostructures made of pure gold The idea is reminiscent of the ancient alchemists'...
Fraunhofer researchers have developed an energy-saving display that reduces the power consumption to a fraction.Credit: © Photo Fraunhofer FEP Data glasses mirror information to the eye without interfering with the wearer's vision. However, the battery runs down quickly, because the electronics...
Computer visualisation of villi-like battery material.Credit: Teng Zhao A new prototype of a lithium-sulphur battery -- which could have five times the energy density of a typical lithium-ion battery -- overcomes one of the key hurdles preventing their commercial development...
Sludge from Metro Vancouver’s wastewater treatment plant has been dewatered prior to conversion to biocrude oil at Pacific Northwest National Laboratory.Courtesy of WE&RF It may sound like science fiction, but wastewater treatment plants across the United States may one day...
Post-doctoral researcher Congcong Wu, who is working in the lab of Shashank Priya, the Robert E. Hord Jr. Professor of Mechanical Engineering, holds up a layer of the flexible solar panel the group is working on. The process to...
This isotropic, neodymium-iron-boron bonded permanent magnet was 3-D-printed at DOE's Manufacturing Demonstration Facility at Oak Ridge National Laboratory. Credit: Oak Ridge National Laboratory Researchers at the Department of Energy's Oak Ridge National Laboratory have demonstrated that permanent magnets produced by...
Micro drums enable a nearly noiseless measurement of radio signals. The drum is made of thin superconducting aluminium film on top of a quartz chip (blue background). Credit: Mika Sillanpää   Extremely accurate measurements of microwave signals can potentially be used...
Oil droplet in Water. Dual superlyophobic surface keeps oil droplet separate in water when it is against the surface. Credit: Xuelin Tian, Robin Ras Researchers of Aalto University have developed new surface materials that are extremely difficult to wet both by...
