This paper describes a minimal implementation of a cryptographically secure electronic voting system, built with a low-cost Xilinx FPGA board. This system, called VoteBox Nano, follows the same basic design principles as VoteBox, a full-featured electronic voting system. As with VoteBox, the votes are encrypted using Elgamal homomorphic encryption and the accuracy of the system can be challenge...

The boron (Z = 5) element is unique. Boron-based (nano-)materials are equally unique. Accordingly, the present special issue is dedicated to crystalline boron-based (nano-)materials and gathers a series of nine review and research articles dealing with different boron-based compounds. Boranes, borohydrides, polyhedral boranes and carboranes, boronate anions/ligands, boron nitride (hexagonal str...

The phase stability and electronic structure of alpha- LiBH(4)-derived nanostructures and possible low energy surfaces of thin films have been investigated using the ab initio projected augmented plane wave method. Structural optimizations based on total energy calculations predicted that, for the alpha- LiBH(4) phase, the (010) surface is the most stable of the possible low-energy surfaces. Th...

We discuss a novel nano-electronic computing paradigm in which cells composed of interacting quantum dots are employed in a locally-interconnected architecture. We develop a network-theoretic description in terms of appropriate local state variables in each cell.

We report on a possibility of efficient engineering of the acoustic phonon energy spectrum in multishell tubular structures produced by a novel high-tech method of self-organization of microand nano-architectures. The strain-driven roll-up procedure paved the way for novel classes of metamaterials such as single semiconductor radial microand nano-crystals and multi-layer spiral microand nano-su...

A "Darwin Machine" is defined to be a piece of hardware that evolves its own architecture at electronic speeds. A Darwin Machine is an example of "Evolutionary Engineering", which in turn is defined to be the building of complex structures and dynamics using evolutionary methods. The author believes that evolutionary techniques will dominate 21st century engineering, especially molecular scale ...

This paper represents the lowest growth temperature for silicon nano-wires (SiNWs) via a vapour-liquid-solid method, which has ever been reported in the literature. The nano-wires were grown using plasma-enhanced chemical vapour deposition technique at temperatures as low as 150°C using gallium as the catalyst. This study investigates the structure and the size of the grown silicon nano-structu...

The modeling of nano-electronic devices is a cost-effective approach for optimizing the semiconductor device performance and guiding fabrication technology. In this paper, we present capabilities new flexible multi-scale nano TCAD simulation software called Nano-Electronic Simulation Software (NESS). NESS designed to study charge transport in contemporary novel ultra-scaled devices. order simul...

Electron transport properties of pure and Oxygen and/or Methyl substituted pyrene between two semi-infinite Aluminum atomic electrodes have been investigated by means of density functional theory plus the non-equilibrium green’s function method. The electrodes were represented by a slab of Al atoms oriented along the [111] plane. The computations were carried out in the bias voltage range of 0....

Nano ZnO/ montmorillonite composite were prepared by sol gel method under ultrasonic irradiation from directly mixing montmorillonite nano clay into Zinc gel. The Zn(CH3COO)2.2H2O and montmorillonite nano clay was used as precursor. The zinc acetate was dissolved in DI water and, NH3 (aq) solution was dropped into the zinc solution until pH 9 consequently the zinc gel was produced. The montmori...
