Scientists explore how doping affects the charge properties of a photocatalyst. This research will accelerate the development of artificial photosynthesis technologies.
Optical tweezers used to trap nanoscale objects usually require a tightly focused laser beam with high optical intensity. The problem with all conventional laser-based optical manipulation techniques is that the laser light could cause photodamages and photothermal degradation to nanoparticles and biological samples. A novel solution to this problem creates a low-temperature spot in the solution and trap particles and molecules at the cold spot. This new technique can effectively avoid ...
Researchers have developed a two-dimensional alloy material - made from five metals as opposed to the traditional two - and shown it to act as an excellent catalyst for reducing CO2, into CO, with potential applications in environmental remediation.
The new instrument will enable the precise generation of nanoscale particles of diverse materials by the method of gas-phase condensation, their size-selection with a mass spectrometer and then deposition onto surfaces to make prototype devices.
A new technique reveals the fundamental physics of how a polymer such as DNA threads through holes 10,000 times smaller than the width of a human hair.
The electronic properties of graphene can be specifically modified by stretching the material evenly. These results open the door to the development of new types of electronic components.
Scientists succeeded in imaging the photocatalytic function of nanoparticles with unprecedently high resolution, which may provide a new tool for nanotechnology and optical manipulation of tiny devices.
An electronic patch can monitor your sweating and check your health status. Even more, the soft microfluidic device that adheres to the surface of the skin, captures, stores, and performs biomarker analysis of sweat as it is released through the eccrine glands.
Researchers have developed a single metasurface that can effectively tune the different properties of laser light, including wavelength, without the need of additional optical components. The metasurface can split light into multiple beams and control their shape and intensity in an independent, precise and power-efficient way.
