Drilling with the beam of an electron microscope, scientists precisely machined tiny electrically conductive cubes that can interact with light and organized them in patterned structures that confine and relay light's electromagnetic signal. This demonstration is a step toward potentially faster computer chips and more perceptive sensors.
Humans experience the world in three dimensions, but scientists have developed a way to create synthetic dimensions to better understand the fundamental laws of the Universe and possibly apply them to advanced technologies.
Scientists obtained a catalyst composed of the hollow carbon sphere and inner Ni nanoparticles, which displayed good performance when applied in the aqueous phase hydrogenation rearrangement tandem reaction of furfural, a typical aqueous phase reaction.
A newly created nano-architected material exhibits a property that previously was just theoretically possible: it can refract light backward, regardless of the angle at which the light strikes the material.
By replacing gold film with graphene, researchers have improved the performance of opto-thermoelectric tweezers. These new graphene-based opto-thermoelectric tweezers benefits from a much broader working wavelength range and a larger trapping area. They extend the working wavelength from visible band to the infrared and far-infrared bands, which are less harmful to biological samples. Owing to the ultrahigh thermal conductivity of graphene, this technology can achieve large-area particle ...
The key to this novel technique is that the nanotubes pull the liposomes and the cancer cells together, allowing the membranes of the liposome and cancer to mix. This fusion process allows the drug to freely pass from the liposome to the cell.
