Nanotechnology - Better measurements of single molecule circuits
Researchers have developed a method to measure the conformation of single molecule 'wiring', resolving a clash between theoretical predictions and experiments.
Monitoring the real-time deformation of carbon nanocoils under axial loading
Scientists describe the real-time deformation data that exhibited sequential change in carbon nanocoil geometry after each coil was subjected to a uniaxial load at a constant rate.
Gold nanoparticles used for drug delivery could disrupt a woman's fertility
A recent study has found that while engineered gold nanoparticles are attractive for smart drug delivery, they come with a downside: great potential to disrupt a woman's fertility.
A novel approach for high performance field emission electron sources
Scientists have reported an original approach for the development of novel graphenated multiwalled carbon nanotubes with enhanced field electron emission properties.
Researchers developed a cost-effective and efficient electrocatalyst rival for platinum
Platinum has traditionally been used as the electrocatalyst in electrolysers that store electric energy as chemical compounds. However, platinum is a rare and expensive metal. Now, researchers have succeeded in developing a substitute to it that is cheap and effective.
Gold nanotubes for theranostic applications
Researchers have exploited gold nanotubes with controlled length and tunable absorption in the near-infrared (NIR) region for applications as photothermal conversion agents and in vivo photoacoustic imaging contrast agents. They developed a length-controlled synthesis to fabricate gold nanotubes with well-defined shape, high crystallinity, and tunable NIR surface plasmon resonance.
New paper-like nanomaterial could boost electric vehicle batteries
Researchers create silicon nanofibers 100 times thinner than human hair for potential applications in batteries for electric cars and personal electronics.
How to make silver nanowires almost indestructible
Researchers found that silver nanowires can be made almost indestructible and highly bendable by covering the minuscule wire with silicon dioxide. The new material can be used for making next generation optical cables, which until now have been easily fractured if bent. The new material 'memorizes' its original position and regenerates when needed.
Extremely repellent surfaces
A computational technique reveals how tiny pillars affect the condensation of vapor onto a surface.
Discovery of a factor that determines the photocatalytic activity of titanium dioxide
Researchers have discovered through the in situ observation of the behavior of photoexcited carriers on the surface of a titanium dioxide crystal used as a photocatalyst that the carrier (electron and positive hole) lifetime on the crystal surface is an important factor to determine the catalytic activity.
Three-dimensional opto-electric integration
Depositing different materials on top of bulk silicon wafers enables three-dimensional opto-electric integration.
