摘要： Examples of an apparatus for dispensing a powdered material are described. The dispensing apparatus comprises a dispenser with an inlet and a dispensing opening, and a vibrating system that is in communication to the dispenser and which provides a continuing periodic oscillation of the dispenser. The apparatus further comprises a controller in communication with a driver of the vibrating system to control a frequency, amplitude and duration of the vibrations such that the powdered material continuously flows out through the dispensing opening during vibration of the dispenser.

摘要： A plasmonic hierarchical structure according to an embodiment includes a nanogap formed between metal nanoparticles. The nanogap has a width of 1 nm to 100 nm. The metal nanoparticles comprise at least one selected from the group consisting of gold (Au), silver (Ag), copper (Cu), platinum (Pt), and palladium (Pd). The plasmonic hierarchical structure further includes silica (SiO2) nanoparticles or CdSe quantum dots. A method for producing a plasmonic hierarchical structure according to an embodiment includes: injecting a metal nanoparticle solution into a micropipette; releasing the metal nanoparticle solution by bringing the micropipette into contact with a substrate; and forming a meniscus of the released metal nanoparticle solution, thereby producing a plasmonic hierarchical structure.
