Bio MoreNowadays demands for clean power source enhanced. Bio-fuel cell (BFC) can convert chemical energy to electrical energy. The enzyme-based biofuel cell (BFC) is a special fuel cell using enzyme as catalyst and can directly convert chemical energy to electrical energy. Bio-fuel cells are energy conversion devices based on bio-electrocatalysis leveraging on enzymes or microorganisms. Enzymatic fuel cells are promising low cost, compact and flexible energy resources. The basis of enzymatic fuel cells is transfer of electron from enzyme to the electrode surface and vice versa.. The DET of laccase enzyme has been studied using Multi-walled carbon nanotubes (MWCNTs)/Nafion polymer. Laccase was entrapped by nafion polymer . As Nafion is a proton exchange polymer but not an electron conductive, the MWCNTs were also used to facilitate electron transfer of laccase. Cyclic voltammetric results showed a well-defined redox peaks at 170 µA in a solution containing 10 µM o-dianisidine as a substrate for MWCNTs/Nafion composite. The cyclic voltammetric results showed that laccase immobilization on MWCNTs/Nafion is efficient. Therefore, this method can be used to fabricate biocathode of biofuels cellor laccase based biosensors. Manuscript profile -

The approximate circuits are more useful in error-resilient applications, like image processing. This paper introduces a new imprecise 4:2 compressor with 12 transistors. The presented compressor exhibits low power consumption and provides full-swing outputs, due to the utilization of gate diffusion input and dynamic threshold techniques. The implementation of this compressor using a 16 nm carbon nanotube field-effect transistor (CNTFET) technology yields a minimum area. According to the simulation results, the suggested imprecise 4:2 compressor shows a significant reduction in power consumption and power-delay-product (PDP) compared to the precise 4:2 compressor, with a reduction of 95.18% and 95.27%, respectively. Also, the compressor is evaluated regarding the approximate figure of merits like error rate, mean error distance, and normalized mean error distance. The simulation results affirm the priority of the suggested circuit, especially in digital signal processing. Manuscript profile -

The proposed circuits are implemented based on gate diffusion input (GDI) and dynamic threshold (DT) techniques and are named Proposed-1 and Proposed-2. The Proposed-1 subtractor has 10 transistors, while Proposed-2 has 12 transistors. Subtractors are implemented by 32 nm carbon nanotube field effect transistor (CNTFET) technology. Various studies have been performed and show the high efficiency and performance of the circuits in different conditions without reducing their output voltage, which is caused by the use of DT in their implementation. The proposed circuits use XOR and NOT gates, both of which have 4 out of 8 error states. The presented subtractors can be implemented in an unsigned non-recovery divider with different structures including vertical, horizontal, square and triangular, etc., and finally, they can be used in image processing applications to detect the difference between two images, either medical or standard images. The simulation results show the better performance of the proposed circuits, Proposed-1 and Proposed-2 save PDP of 88.36% and 83.25%, respectively. Manuscript profile -

They have unique properties and characteristics. They have unique properties and characteristics. Carbon nanotubes have strong bonds between their atoms, and for this reason, they show great resistance and strength against tensile forces. But interatomic bonds in nanotubes, in addition to creating high strength, enable easy plasticity and even twisting in them. While steel only has resistance against tensile forces and does not have the necessary flexibility for twisting. The methods used to produce carbon nanotubes include laser ablation, electric arc discharge, chemical vapor deposition, plasma enhanced chemical vapor deposition, pulsed laser deposition, use of low-frequency ultrasound, bulk polymer heating, and bulk sputtering. CNTs have very good mechanical and thermal properties that strongly depend on their structure. Functionalized magnetic CNTs are involved in magnetic force microscopy used in biomedicine. The liquid and plastic limit of kaolinite can be increased by adding CNT to it. In the field of medicine, CNTs have many applications, including gene transfer to cells, cancer therapy, drug delivery, and tissue regeneration. Their antioxidant nature also allows them to be used in cosmetic and dermatological products. The most important property of nanotubes is their electrical conductivity, which varies depending on the arrangement of atoms. applications and their properties can be improved by making their composites with metals. Such metals may be introduced into the core of carbon nanotubes by various methods including solid state reaction, arc discharge method and electrochemical techniques. The amount of hydrogen gas absorbed in CNTs varies between 0.4 and 67% by mass. Manuscript profile -

For this purpose, in this paper, a new low voltage XOR cell based on Carbon Nanotube Field Effect Transistor (CNTFET) is proposed. The main design goals for this new circuit are low power dissipation, low leakage current and full voltage swing at a low supply voltage (Vdd = 0.5 V). Several XOR circuits were completely simulated using HSPICE with 32nm CMOS and 32nm CNTFET technologies at a low supply voltage. The proposed XOR circuit is compared with the previously known circuits and its outstanding performance is shown. Simulations show that the new low voltage XOR has lower power dissipation, less leakage current and lower PDP than other XOR circuits, and is resistant to process variations. Based on the results obtained at Vdd=0.5 V ,frequency=250 MHz and Cload=3.5 fF, the proposed XOR shows propagation delay of 149.05 ps, power consumption of 716.72 pW, leakage power of 25.1 pW and PDP of 10.683x10-21 J. The proposed XOR can be used well in low voltage and low power Full Adder circuits. Manuscript profile -

This study compares the detection of this bacterium by regular method and a biosensor based on Multi-Walled Carbon Nanotubes (MWCNTs) on glassy carbon electrodes (GCE) in pharmaceutical and water as real sample. Materials and Methods: In this experimental study, the conventional culture method (pour plate) and modified biosensor based on Multi-Walled Carbon Nanotubes on glassy carbon electrode with the arrangement of GC/MWCNTs/AuNPs/Ab/BSA were used for the detection of E. coli. Dilutions of E. coli between (1 ×101–1×108 CFU/ml) were used in pharmaceutical and water samples, prepared in 0.1 M PBS (pH 7.4), mixed with 0.5mM acetaminophen. The efficiency of the designed biosensor was investigated using SEM, Cyclic Voltammetry, and Square-Wave Voltammetry electrochemical techniques, as well as interfering bacteria. Results: The results of E. coli detection using the conventional culture and designed biosensor were not statistically significant. The designed biosensor had a high sensitivity with accuracy in 3 minutes and LOD 3.02 CFU/ml for Escherichia coli. Conclusion: Considering the time-consuming and influenced by environmental factors in the microbial monitoring of pharmaceuticals for E. coli detection in conventional methods and the risk of losing pharmaceutical products, the biosensor has good efficiency in detection with low cost and no need for enrichment in a small volume of samples.

Accurate determination of the properties of carbon nanotubes, including the coefficient of thermal expansion, has many practical problems due to the limitations of laboratory methods. In this study, molecular dynamics method has been used to investigate and extract the properties of thermal expansion coefficient in a number of samples of carbon nanotubes that have different diameters and armchair and zigzag structures. In this study, the effect of atomic structure defects including Stone–Wales and vacancy defects on the coefficient of thermal expansion and longitudinal elastic mechanical properties of carbon nanotubes have been investigated. The potential function used in COMPASS simulation. Based on the obtained results, the coefficient of thermal expansion for CNT (7,7) at a temperature of 800 K is calculated at about 6.34 , which shows a good agreement with the results of laboratory studies. Also, the presence of defects in the atomic structure, including the defect of the non-reconstructed vacancy, in most cases has increased the coefficient of thermal expansion, which has been equal to 65% in CNT (0, 7). The vacancy defect is more effective than the Stone-Walsh defect in changing the coefficient of thermal expansion. The results show that the elastic properties of the CNT case study are also weakened by 22% due to the defect of the vacancy in the longitudinal direction. Manuscript profile -

71 - The effect of (nano, mesoporous) alumina and their composite with MWCNT additives on microstructure, physical and mechanical properties of alumina-C refractories

Following in order to physical and mechanical properties investigation, all samples pressed under 150Mpa pressure by uniaxial then pressed and tempered at 200 ℃ for 6h, and afterward fired under coke atmosphere at 1450℃ for 2 h.The bulk density apparent porosity and cold crushing strength were determined according to their respective standard. Moreover their microstructure and phase analysis was investigated by XRD and SEM.The results confirmed that the sample containing1wt% nano Al2O3-MWCNT composite showed the highest CCS of about 137 Mpa,and sample with1.5 wt% mesoporous Al2O3 showed the lowest CCS (94 Mpa).The improvement of mechanical properties could be related to the higher SiC formation in the presence of nano Al2O3- MWCNT by vapor- solid mechanism. The main reason for decreasing mechanical properties in the presence of mesoporous additives could be attributed to limiting of gas-solid reaction due to trap of gases and therefore lower formation of SiC whiskers through the matrix.

On MoreUltra high molecular weight polyethylene (UHMWPE) has been used as the material of choice in joint replacement prosthesis as an articular component for several years. Despite its distinct physical and chemical characteristics, the lifespan of this polymer is limited. One approach to increase the lifespan and mechanical properties is the use of multi-walled carbon nanotubes (MWCNT). Multi-walled carbon nanotubes are promising candidates for use as a filler phase in polymers due to their excellent mechanical properties and excellent surface-to-volume ratio. In this research, the addition of 0.1% by weight of multi-walled carbon nanotubes functionalized with carboxyl groups was investigated on the mechanical properties and biocompatibility of the UHMWPE base matrix and its comparison with the pure UHMWPE sample. Fourier transform infrared spectroscopy (FTIR) confirmed the presence of characteristic peaks of UHMWPE and carbon nanoparticle in the matrix. X-ray diffraction (XRD) showed an increase in the intensity of the characteristic peaks of the composite compared to the pure sample. The differential scanning calorimetry test (DSC) showed an increase of about 10% in the crystallinity of the composite containing carbon nanotubes (PE/MWCNT). The dynamic mechanical thermal analysis (DMTA) showed an increase of about 22% in the storage modulus compared to the control sample, and finally, the cell viability through the cell culture test in the PE/MWCNT composite showed a 15 % increase in cell viability. According to mechanical and biocompatibility results, the composite sample can perform better in terms of mechanical loads in bearing surfaces compared to pure UHMWPE. Manuscript profile -

This study focuses on two types of nanocarriers: single-walled carbon nanotubes and boron nitride nanotubes, each of which carries a drug with an alkylating agent: chlorambucil. This research investigates the stability of these carriers at different temperatures and solvent conditions. Using quantum mechanical calculation methods, the interaction between the anticancer medicinal compounds chlorambucil with two nanocarriers (carbon nanotubes and boron nitride nanotubes) was investigated in a range of temperatures and different solvent environments. Checking the thermodynamic parameters through molecular mechanics calculations, the hardness, polarity, Gibbs free energy parameters, as well as the HOMO and LUMO gap of the compounds were calculated. Also, using molecular mechanics calculations, optimal force fields and lowest energy states were determined in each solvent. The findings of this research are promising for the development of targeted drug delivery systems and the preservation of these vital medicinal compounds. Manuscript profile
