    • A method for making a series of nanoscale microstructures, including helical microstructures and cylindrical microstructures. This method includes the steps of: (1) forming a chiral block copolymer containing a plurality of chiral first polymer blocks and a second polymer blocks wherein the chiral first polymer blocks have a volume fraction ranging from 20 to 49%; (2) causing a phase separation in the chiral block copolymer. In a preferred embodiment, the chiral block copolymer is poly(styrene)-poly(L-lactide) (PS-PLLA) chiral block copolymer, and the copolymerization process is a living copolymerization process which includes the following steps: (a) mixing styrene with BPO and 4-OH-TEMPO to form 4-hydroxy-TEMPO-terminated polystyrene; and (2) mixing the 4-hydroxy-TEMPO-terminated polystyrene with [(η3-EDBP)Li2]2[(η3-nBu)Li(0.5Et2O)]2 and L-lactide in an organic solvent preferably CH2Cl2 to form the poly(styrene)-poly(L-lactide) chiral block copolymer. Transmission electron microscopy (TEM) and small X-ray scattering (SAXS) studies show that when the volume fraction of poly(L-lactide) is about 35-37%, nanoscale helices with a pitch of 43.8 nanometers and a diameter of 34.4 nanometers were observed.

    • A light-emitting diode (LED) street lamp is applicable for street lighting. The LED street lamp includes a casing, an LED module, and a heat dissipation module. The LED module and the heat dissipation module are arranged inside the casing. The LED module includes a frame, a circuit board carrying a plurality of LEDs, and a light regulation mechanism. The frame and the circuit board are set opposing each other with the light regulation mechanism arranged therebetween to interfere with emission light from the LEDs. The emission light, after being interfered with, is projected outside the casing to realize lighting. The heat dissipation module is in physical engagement with the LED module to remove heat generated by the LEDs. As such, the LED street lamp is provided with a broader range of illumination angle and more uniform brightness, so that the same LED street lamp is applicable to various sites and the heat generated by the LEDs can be efficiently dissipated.
