“…We summarize some of the representative works with respect to CNTs-based nano-mass sensor adopting FEM [ 126 , 127 , 128 , 129 , 130 , 131 , 132 ], Euler–Bernoulli beam theory (EBT) [ 127 , 129 , 131 , 135 , 138 , 140 ], nonlocal EBT [ 133 , 134 , 136 , 139 , 142 , 143 , 144 ], Timoshenko beam theory (TBT) [ 141 ], nonlocal TBT [ 137 ] for studying CNTs-based nano-mass sensors as shown in Table 1 , from which we can see that though the work considering thermal and nonlocal effects could make sensitivity to atom mass of 6.65 × 10 −24 g and 0.218 × 10 −24 g under special thermal conditions [ 143 , 144 ], most of the works indicated that the CNTs-based nano-mass sensor could detect tiny mass larger than 10 −21 g. Moreover, detail of CNTs-based nano-mass sensor can be also found in some previous review works [ 18 , 145 ].…”

Carbon nanomaterials, such as carbon nanotubes (CNTs), graphene sheets (GSs), and carbyne, are an important new class of technological materials, and have been proposed as nano-mechanical sensors because of their extremely superior mechanical, thermal, and electrical performance. The present work reviews the recent studies of carbon nanomaterials-based nano-force and nano-mass sensors using mechanical analysis of vibration behavior. The mechanism of the two kinds of frequency-based nano sensors is firstly introduced with mathematical models and expressions. Afterward, the modeling perspective of carbon nanomaterials using continuum mechanical approaches as well as the determination of their material properties matching with their continuum models are concluded. Moreover, we summarize the representative works of CNTs/GSs/carbyne-based nano-mass and nano-force sensors and overview the technology for future challenges. It is hoped that the present review can provide an insight into the application of carbon nanomaterials-based nano-mechanical sensors. Showing remarkable results, carbon nanomaterials-based nano-mass and nano-force sensors perform with a much higher sensitivity than using other traditional materials as resonators, such as silicon and ZnO. Thus, more intensive investigations of carbon nanomaterials-based nano sensors are preferred and expected.

“…Recently, Carbon Nanotubes (CNTs) have come to the fore as most promising materials and are being considered for a wide variety of applications ranging from large-scale structure to nanometer-scale electronics because of their superior mechanical and physical properties [32,33]. CNTs were discovered accidentally by Japanese physicist S. lijima [34] in 1991 when performing experiments on carbonium. CNTs are basically nano-scaled tubes formed by the rolled sheets of graphite and possess high tensile strength, high electrical conductivity and excellent chemical stability [35].…”

Due to the difficulties associated with scaling of silicon transistors, various technologies beyond binary logic processing are actively being investigated. Ternary logic circuit implementation with carbon nanotube field effect transistors (CNTFETs) and resistive random access memory (RRAM) integration is considered as a possible technology option. CNTFETs are currently being preferred for implementing ternary circuits due to their desirable multiple threshold voltage and geometry-dependent properties, whereas the RRAM is used due to its multilevel cell capability which enables storage of multiple resistance states within a single cell. This article presents the 2-trit arithmetic logic unit (ALU) design using CNTFETs and RRAM as the design elements. The proposed ALU incorporates a transmission gate block, a function select block, and various ternary function processing modules. The ALU design optimization is achieved by introducing a controlled ternary adder–subtractor module instead of separate adder and subtractor circuits. The simulations are analyzed and validated using Synopsis HSPICE simulation software with standard 32 nm CNTFET technology under different operating conditions (supply voltages) to test the robustness of the designs. The simulation results indicate that the proposed CNTFET-RRAM integration enables the compact circuit realization with good robustness. Moreover, due to the addition of RRAM as circuit element, the proposed ALU has the advantage of non-volatility.

The character table or the table of eigen values for the D7h point group, which is not found in the literature was constructed. The constructed table is used to classify all modes of the vibrational frequencies of the IR and Raman spectra for any compound or molecule that has the D7h symmetry in the Point Group. For that, it was used for classifying all the modes of vibrational frequencies of the [7] cyclacene (linear) monitoring molecule, possessing D7h symmetry. The constructed table was used to classify the symmetry species for the total degrees of freedom, total degrees of transition, total degrees of rotation and for the total degrees of modes of vibration (3N-6) for this tube. The character table was also used to determine the active and inactive modes of vibration in the IR and Raman spectra.Also,determining the polarized and non-polarized vibrational frequencies in the Raman spectrum, and used for describing the complete physical structure of the studied molecule after extracting its geometric shape. The methods of quantum mechanics calculations PM3 and DFT were used for this purpose applying the Gaussian 09 program.
