Three-dimensional (3D) electrodes are critical for enabling high-performance power sources. We report here on the design and fabrication, by combining imprint and soft-printing technologies, of 3D nanocone arrays as a novel platform for high performance pseudocapacitors. Such purpose-built 3D nanocone arrays have the advantages of simplicity/versatility/reliability of fabrication, generality to...

High aspect ratio diamond nanocone arrays are formed on freestanding diamond film by means of focused ion beam (FIB) milling technology and hot-filament chemical vapor deposition (HFCVD) method. The structure and phase purity of an individual diamond nanocone are characterized by scanning electron microscopy (SEM) and micro-Raman spectroscopy. The result indicates that the diamond cones with hi...

5-Fluorouracil (5-FU) is an anticancer drug. In this work, we have investigated the electronic properties and topological analysis of interaction between 5-FU and carbon nanocone and BN nanocone. The structural stability of isomer complexes of 5-FU with carbon nanocone and BN nanocone have been investigated for two position of interactions. We have found that the most stable complexes are forme...

 In this paper, the performance of carbon nanocone as an ideal adsorbent and sensing material for tetryl was investigated by density functional theory. For this aim, the structures of tetryl, carbon nanocone and their complexes were optimized geometrically. Afterwards, IR and FMO computations were done on them. The obtained thermodynamic parameters showed the interaction of car...

We demonstrated fabrication of black silicon with slanted nanocone array on both planar and 3D micro and meso scale structures produced by a high-throughput lithography-free oblique-angle plasma etching process. Nanocones with gradual change in height were created on the same piece of silicon. The relation between the slanted angle of nanocones and incident angle of directional plasma is experi...

In this work, we study the mechanism of nanocone formation on a surface of elementary semiconductors by Nd:YAG laser radiation. Our previous investigations of SiGe and CdZnTe solid solutions have shown that nanocone formation mechanism is characterized by two stages. The first stage is characterized by formation of heterostructure, for example, Ge/Si heterostructure from SiGe solid solutions, a...

The diamond or graphene lattices may be expanded theoretically by replacing one or several CC bonds of each carbon atom by the sequence C−(C≡C)k−C with k = 1, 2, etc. In this communication a systematic approach is described, by operating these replacements according to the four directions around an sp-hybridized carbon atom (affording “mdirectional diamond-yne”) with m = 1 to 4 or the three dir...

ZnO nanocone arrays on self-assembled Zn2SnO4 base were successfully synthesized via a thermal evaporation method of two-step temperature-rising. The as-prepared ZnO nanocone products had a well crystalline wurzite structure with symmetry about the growth direction along [0001]. Based on the calculation of the lattice misfit between different families of crystal planes of ZnO and Zn2SnO4, Stran...

A new technique to automatically segment the L-shaped carbon nanocone structures from Transmission Electronic Microscopy (TEM) images is described. The technique enables robust segmentation of the structures by exploiting a simplified Generalized Hough Transform (HT)-based processing. Exploitation of parallelism on commodity hardware is also explored for efficient processing. Effectiveness of t...
