Abstract: A device for fabricating a quartz microfluidic chip by a femtosecond pulse cluster. The device includes: a femtosecond pulse cluster laser source configured to output a femtosecond pulse cluster; a beam splitting and interference system, configured to split the femtosecond pulse cluster into a plurality of parts, and to converge split parts to form a femtosecond pulse cluster plasma or a femtosecond pulse cluster plasma grating; a sample system configured to move the electronic displacement platform where a quartz glass is placed to control a position where the parts of the femtosecond pulse cluster are converged on the quartz glass; and a hydrofluoric acid immersion system configured to immerse the quartz glass in a diluent hydrofluoric acid solution to remove an ablated part of the quartz glass to form the quartz microfluidic chip.

Abstract: A glass fiber filter element for visible light photocatalysis and air purification and a method for preparing the same. The glass fiber filter element includes 4 to 7 wt % of nanoparticles including at least one selected from zinc oxide, graphene oxide, titanium oxide, and reduced graphene oxide, 2 to 7 wt % of silver nanowires, 3 to 12 wt % of an adhesive system, and 78 to 91 wt % of a glass fiber mat, based on the total weight of the glass fiber filter element. The glass fiber mat is made of at least two glass fibers with different diameters, and the diameters are in a range of 0.15 to 3.5 ?m. The nanoparticles have a particle size from 1 to 200 nm, and the silver nanowires have a diameter of 15 to 50 nm.
