TL;DR: In this paper, a review of the fundamental problems associated with QD-based solar cells is presented, including unrealistic assumptions involved in theoretical work, tendency of stretching observed experimental results, and lack of both process and dimension control at nanoscale.
Abstract: Quantum dot (QD)-based solar cells have been the subject of over two decades of research with the hopes of increasing their efficiency to surpass single junction solar cells. To date, no single working device has been developed that surpasses the efficiency of a single junction solar cell. Fundamental issues including unrealistic assumptions involved in theoretical work, tendency of stretching observed experimental results, and lack of both process and dimension control at nanoscale exist with QD-based solar cells making them unlikely to play a significant role in the manufacturing of future generations of PV modules. Silicon (Si)-based photovoltaics (PV) manufacturing will continue to provide sustained growth of the PV industry. This paper presents a review of the fundamental problems associated with QD-based solar cells.

TL;DR: A novel quantum-dot cellular automata adder design is presented that reduces the number of QCA cells compared to previously reported designs and requires only about 70% of the hardware compared to previous designs with the same speed and clocking performance.
Abstract: In this paper, a novel quantum-dot cellular automata (QCA) adder design is presented that reduces the number of QCA cells compared to previously reported designs. The proposed one-bit QCA adder structure is based on a new algorithm that requires only three majority gates and two inverters for the QCA addition. By connecting n one-bit QCA adders, we can obtain an n-bit carry look-ahead adder with the reduced hardware while retaining the simple clocking scheme and parallel structure of the original carry look-ahead approach. The proposed adder is designed and simulated using the QCA Designer tool for the four-bit adder case. The proposed design requires only about 70% of the hardware compared to previous designs with the same speed and clocking performance.

TL;DR: The design of a molecular communication system based on intercellular calcium signaling networks is described and possible functionalities that may be achieved in such networks are described.
Abstract: Molecular communication is engineered biological communication (e.g., cell-to-cell signaling) that allows nanomachines (e.g., engineered organisms, artificial devices) to communicate through chemical signals in an aqueous environment. This paper describes the design of a molecular communication system based on intercellular calcium signaling networks. This paper also describes possible functionalities (e.g., signal switching and aggregation) that may be achieved in such networks.

TL;DR: In this article, a simple one-step method is presented for synthesizing large single crystal graphene domains on melted copper using atmospheric pressure chemical vapour deposition (CVD), achieved by performing the reaction above the melting point of copper (1090 °C) and using a molybdenum support to prevent the copper from dewetting.
Abstract: A simple one-step method is presented for synthesizing large single crystal graphene domains on melted copper using atmospheric pressure chemical vapour deposition (CVD). This is achieved by performing the reaction above the melting point of copper (1090 °C) and using a molybdenum support to prevent balling of the copper from dewetting. By controlling the amount of hydrogen during growth, individual single crystal domains of monolayer graphene greater than 200 µm are produced, determined by electron diffraction mapping. Angular resolved photoemission spectroscopy is used to show the graphene grown on copper exhibits a linear dispersion relationship and has no sign of doping.

TL;DR: Simulation by Cadence's Spectre in TSMC 65nm process has shown that the proposed designs consume less power and have better performance compared to the accurate XOR/XNOR-based adder, while the error distance remains similar or better than other approximate adder designs.
Abstract: Power dissipation has become a significant issue for integrated circuit design in nanometric CMOS technology To reduce power consumption, approximate implementations of a circuit have been considered as a potential solution for applications in which strict exactness is not required In inexact computing, power reduction is achieved through the relaxation of the often demanding requirement of accuracy In this paper, new approximate adders are proposed for low-power imprecise applications These adders are based on XOR/XNOR gates with multiplexers implemented by pass transistors The proposed approximate XOR/XNOR-based adders (AXAs) are evaluated and compared with respect to energy consumption, delay, area and power delay product (PDP) with an accurate full adder The metric of error distance is used to evaluate the reliability of the approximate designs Simulation by Cadence's Spectre in TSMC 65nm process has shown that the proposed designs consume less power and have better performance (such as a lower propagation delay) compared to the accurate XOR/XNOR-based adder, while the error distance remains similar or better than other approximate adder designs
