A class of four-parameter solvable profiles of the electromagnetic admittance has recently been discovered by applying the newly developed Property & Field Darboux Transformation method (PROFIDT). These profiles are highly flexible. In addition, the related electromagnetic-field solutions are exact, in closed-form and involve only elementary functi...
Similar to raspberry-like particles with dual-size roughness, dendrimer-like porous silica nanospheres (DPSNs) have great potentials to fabricate superhydrophobic nano-coatings due to facile and controllable synthesis, center-radial large pores and interconnected wrinkles on particle surface. However, there are very limited reports about the effect...
Flexible amorphous silicon (a-Si:H) solar cells with high photoconversion efficiency (PCE) are demonstrated by embedding hexagonal pyramid nanostructures below a Ag/indium tin oxide (ITO) reflector. The nanostructures constructed by nanoimprint lithography using soft materials allow the top ITO electrode to spontaneously form parabolic nanostructur...
We introduce a novel method for fabricating breath figure patterns on a homopolymer film by spin coating of polymer solutions with various solvents. The homopolymers employed in this study were cellulose acetate butyrate, monocarboxylated end-functional polystyrene, and poly(methyl methacrylate). Breath figure patterns were generated even when a wa...

Surface modification by inducing subwavelength structure and porosity is a physically ideal solution for preventing undesirable reflection. In contrast to conventional methods, it is also applicable in solar engineering. In principle, there are several methods that can be employed. Positive results were obtained with sol-gel technology. Antireflect...
