Uniform spherical silver nanoparticles with about 26 nm and good stability were synthesized by facile gallic acid reduction method. The antimicrobial activity of silver nanoparticles was investigated using several representative microbial species including gram-negative bacterium (Escherichia coli), gram-positive bacteria (Staphylococcus aureus, Bacillus subtilis and Streptomyces kanamyceticus) and...
Since most System-on-Chips (SoCs) consist of heterogeneous IP core(s), application-specific Network on Chip (NoC) architectures are appropriate to meet the design requirements. The energy and performance optimization in the NoC design will continue to be the main design goal in nanoscale technologies. In this paper, we present a new hierarchal partitioning approach considering not only the reduction...
Hyperlipidemia is closely related to Cardiovascular Disease, and also an important risk factor to affect Atherosclerosis, Coronary Heart Disease (CHD) and other Cardiovascular Disease. And hyperlipidemia could severely affect the health of human. In order to find better biological activity of lowering blood-lipids, we introduced the target compound of AZ. The lead compound were designed and synthesized...
We have studied the synthesis method of D-glucosamine Complexes with Lead(II), the main factors affecting the reaction and ideal reaction conditions. By the mass spectrometry and IR Spectrum analysis of the complexes, we understand the reaction ratio and coordination situation gradually, and determine the existing of the bond of N-Pb and O-Pb. At last, we Infer the Structure of the Complexes.
A rapid virtual prototype synthesis method for MEMS devices based on element model library and metamodel is proposed in this paper. The goal of the approach is to help designers to establish virtual prototypes of new MEMS devices and find the optimal parameters in a short time. In the proposed method, the virtual prototype is established by connecting reusable and parameterized element models in a...
The reversible logic circuits (RLC) are a sort of novel circuits which can avoid the information loss and energy dissipation by implementing the reversible logic operations. RLC prohibit the feedback and don't have the fan-out, so the synthesis methods of RLC are very different from the existing irreversible logic circuits. In this paper, evolutionary design techniques are applied to the synthesis...
The reversible logic synthesis is a multi-objective optimization problem with rigorous constraints such as prohibiting the feedback and fan-out, and the same number of inputs and outputs, so it is difficult to be solved by general synthesis methods. Moreover, the synthesis methods of reversible logic circuits are very different from that of existing irreversible logic circuits. To make improvements...
A method of optimal antenna pattern synthesis of spaceborne synthetic aperture radar (SAR) based on adaptive genetic algorithm and simulated annealing (AGASA) is presented. The antenna radiation pattern plays an important role in the performance of the spaceborne SAR. High sidelobe level in the antenna pattern leads to high ambiguity-to-signal ratio (ASR), which degrades the quality of the SAR image...
Microfluidic biochips are revolutionizing many areas of biochemistry and biomedical sciences. Several synthesis tools have recently been proposed for the automated design of biochips from the specifications of laboratory protocols. However, only a few of these tools address the problem of droplet routing in microfluidic arrays. These methods typically rely on post-synthesis droplet routing to implement...
Microfluidics-based biochips combine electronics with biology to open new application areas such as point-of-care medical diagnostics, on-chip DNA analysis, and automated drug discovery. Bioassays are mapped to microfluidic arrays using synthesis tools, and they are executed through the manipulation of sample and reagent droplets by electrical means. Most prior work on CAD for biochips has assumed...
