Address correspondence to

A miniature droplet reactor has been built on nanoparticle-derived superhydrophobic pedestals, which provide a confined space and the capability to perform a series of aqueous phase chemical reactions on a small scale. Due to the low-adhesive properties of the substrate, reaction products in liquid or solid states can be collected effectively, providing a promising way to harvest valuable products prepared in limited amounts.

The absorption of one atomic layer graphene can be saturated at quite low excitation intensity and gives a remarkably large modulation depth of 65.9%. Picosecond laser pulses (1.23 ps) can be generated using monolayer graphene as a saturable absorber. A monolayer graphene mode-locked laser shows better pulse stability and higher output energy.
