Scientists have developed an Earth-abundant catalyst based on copper-oxide nanowires modified with tin oxide. A solar-driven system set up using this catalyst was able to split CO2 with an efficiency of 13.4%.
Researchers demonstrate the design and fabrication of stretchable tactile sensors that are 3D printed under ambient conditions via a combination of nanocomposite ink optimization, 3D imaging, and multimaterial 3D printing.
Researchers create a huge variety of programmed three-dimensional shapes out of single strands of synthetic DNA, a process known as DNA origami. These nanoparticles may ultimately be deployed as structural scaffolds to deliver vaccines, drugs, or even gene-editing tools such as CRISPR-Cas9 to specific parts of the body, he says.
Nondestructive scanning near-field thickness resonance acoustic microscopy (SNTRAM) with sharp phase contrast and mechanical sensitivity provides a wide range of applications in nanomechanical imaging of semiconductor structures and a wide range of other materials.
Researchers present a facile approach to overcoming hysteresis to less than 0.5% of the gate-source voltage sweep range: rather than to eliminate traps, they aim to reduce the effect that traps have on the CNTs.
Novel hydrogels not only exhibited remarkable optical response from pale yellow to purple color and from green to red fluorescence under external stimuli of force, heat, and UV light, but also simply reversed its color back to the original one by white light.
Researchers have found a way to make ultralight sponge-like materials from nanoscale ceramic fibers. The highly porous, compressible and heat-resistant sponges could have numerous uses, from water purification devices to flexible insulating materials.
