A facile method, i.e., nonsolvent assisted electrospraying, is proposed to fabricate hierarchically porous microspheres. The pore size on the microsphere surface ranges from a few tens to several hundred nanometers. Thermally and nonsolvent induced phase separation as well as breath figure is responsible for the formation of the hierarchical structures with different nano-sized pores. The nonso...

Phase-separation is commonly observed in multimetallic nanomaterials, yet it not well understood how immiscible elements distribute a thermodynamically stable nanoparticle. Herein, we studied the phase-separation of Au and Rh nanoparticles using electron microscopy tomography techniques. The were thermally annealed to form structures. HAADF-STEM EDS characterizations reveal that segregate into ...

In this paper, the fabrication process and electromechanical properties of novel atomic force microscopy probes utilising single-crystal boron-doped diamond are presented. The developed integrate scanning tips made chemical vapour deposition-grown, freestanding foil. procedure was performed using nanomanipulation techniques combined with electron focused ion beam technologies. mechanical cantil...
