Frontiers of Information Technology & Electronic Engineering 2021, Volume 22, Issue 3,   Pages 287-436 doi: 10.1631/FITEE.2000387

Abstract: Indium selenide (InSe) is a typical layered metal-chalcogenide semiconductor that has potential for developing ultrafast optoelectronic devices. In this work, InSe-polyvinyl alcohol (InSe-PVA) film is employed as saturable absorber and prepared by mixing InSe solution and polyvinyl alcohol solution. The nonlinear absorption properties of the InSe saturable absorber (InSe-SA) are investigated, showing that the nonsaturable absorption and modulation depth are 37.5% and 9.55%, respectively. lasers are generated in erbium-doped fiber (EDF) laser-employed InSe as a mode-locker. The central wavelength and pulse duration of the pulse are 1568.73 nm and 2.06 ps, respectively, under a repetition rate of 1.731 MHz. The maximum average output power is 16.4 mW at the pump power of 413 mW. To the best of our knowledge, this is the first demonstration of a pulse with InSe as a mode-locker. The experimental results further demonstrate that InSe is an outstanding nonlinear absorption material in ultrafast .

Nanomechanical Characteristics of Interfacial Transition Zone in Nano-Engineered Concrete Article

Xinyue Wang, Sufen Dong, Zhenming Li, Baoguo Han, Jinping Ou

Engineering 2022, Volume 17, Issue 10,   Pages 99-109 doi: 10.1016/j.eng.2020.08.025

Abstract:

This study investigates the effects of nanofillers on the interfacial transition zone (ITZ) between aggregate and cement paste by using nanoindentation and statistical nanoindentation techniques. Moreover, the underlying mechanisms are revealed through micromechanical modeling. The nanoindentation results indicate that incorporating nanofillers increases the degree of hydration in the ITZ, reduces the content of micropores and low-density calcium silicate hydrate (LD C-S-H), and increases the content of high-density C-S-H (HD C-S-H) and ultrahigh-density C-S-H (UHD C-S-H). In particular, a new phase, namely nano-core-induced low-density C-S-H (NCILD C-S-H), with a superior hardness of 2.50 GPa and an indentation modulus similar to those of HD C-S-H or UHD C-S-H was identified in this study. The modeling results revealed that the presence of nanofillers increased the packing density of LD C-S-H and significantly enhanced the interaction (adhesion and friction) among the basic building blocks of C-S-H gels owing to the formation of nano-core-shell elements, thereby facilitating the formation of NCILD C-S-H and further improving the performance of the ITZ. This study provides insight into the effects of nanofillers on the ITZ in concrete at the nanoscale.

Jiang Zhuangde,Wang Chenying,Yang Shuming

Strategic Study of CAE 2013, Volume 15, Issue 1,   Pages 15-20

Abstract:

Three types of nano-scale structure have been fabricated and characterized using SEM, AFM, etc. In this paper, multilayer thin film deposition technique has been used to fabricate nano-scale structure with 20nm, 25 nm and 35 nm line-width. LER and LWR of nanoline are evaluated with an offline image analysis algorithm. The experimental results indicate that the LER/LWR of the lines is low and the uniform of the lines is high. EBL and ICP technique are employed to fabricate grating patterns with nominal height 220 nm. The result shows that the high frequency fluctuations of line edges after etching decrease, the correlation length increases and values of root mean square deviation (σ) increase. Single and multiple nano steps have been fabricated using FIB technique, and the relationship between the size of the Z-axis and energy of process are analyzed.

Nano-measuring Instruments and Nano-machining Technology

Yao Junen

Strategic Study of CAE 2003, Volume 5, Issue 1,   Pages 33-37

Abstract:

Nanotechnology is a research and development hot spot nowadays. In this paper a short introduction of nanoscience and nanotechnology was given. Nano-measurement and nano-machining play a very important and key role in the nanoscience and nanotechnology. Conventional electron microscope is a major nano-measuring instrument. Newly developed scanning probe microscope and focused ion beam-electron beam (dual beam) equipment are two types of powerful nano-measuring instruments and nano-machining tools. Its present state, prospect and market in the world as well as in China were described briefly.

The first-two Chinese prototype transmission electron microscopes were constructed in 1958-1959 in Changchun Institute of Optics and Fine Mechanics, CAS. Beijing Scientific Instrument R & D Center (KYKY) developed the first domestic scanning electron microscope. According to a survey in 1996-1997 there were 1 921 electron microscopes including 756 transmission electron microscopes (TEM) and 1 165 scanning electron microscopes (SEM) in China at that time. Of these 1 921 TEMs and SEMs, 1006 were domestic production (mostly medium-and low-grade electron microscopes) accounting for 52.4 % of the market, and 915 instruments were imported (47.6 %). Beijing Scientific Instrument R & D Center, CAS (KYKY Technology Development LTD) , Shanghai electron-Optical Technology Research Institute and Jiangnan Optical Instrument Plant produced more than 95 % of these 1 006 home-made electron microscopes. The first domestic scanning tunneling microscope (STM) was completed in 1987 in Beijing Open Laboratory of Electron Microscopy under CAS. Since then more than one hundred scanning probe microscopes of various types have been constructed in China. The Chinese electron microscope and scanning probe microscope production should be improved and enlarged to cover the progressively increasing demand of research and development work in China.

Study on Strengthening Technique with Prestressed PBO Fiber Sheets

Wu Zhishen,Iwashita Kentaro,Niu Hedong

Strategic Study of CAE 2005, Volume 7, Issue 9,   Pages 18-24

Abstract:

The application of externally bonded fiber reinforced polymer (FRP) laminates to the exposed faces of concrete members provides an innovative and efficient rehabilitation method for strengthening and upgrading structurally inadequate or functionally obsolete concrete structures. However, FRP laminates unlike the cold worked steel exhibit elastic-rupture behavior and also the limited bond capacity of FRP-concrete interface often fails the retrofitted system in an undesirable brittle manner, which leaves FRP material unused with more reserves. Moreover, enhancements in cracking and yield load due to FRP bonding are not significant. To take full advantage of FRP laminates, more gains can be achieved by prestressing the fibers prior to bonding them. Traditional practice is to pretension fiber sheets impregnated with adhesive or FRP plate, which is time-consuming, difficult to apply in the field and ensure a perfect bond at the interface. A newly-developed PBO fiber possesses high modulus, high strength and higher energy absorption capability as compared to carbon and aramid fibers, and PBO fiber sheet can be pretensioned to over 70% of its tensile strength without being impregnated with adhesive. All these make such material suitable to be prestressed for strengthening concrete structures. Based on the experiments and theoretical studies, a comprehensive strengthening method with prestressed PBO sheet is established including concept, working principle and corresponding countermeasures, whose strengthening effect is validated by both laboratory and field experiments.

A fuzzy integrated congestion-aware routing algorithm for network on chip Research Articles

Shahrouz Yasrebi, Akram Reza, Mohammad Nikravan, Seena Vazifedan,a.reza@qodsiau.ac.ir,a.ak.reza@gmail.com

Frontiers of Information Technology & Electronic Engineering 2021, Volume 22, Issue 5,   Pages 615-766 doi: 10.1631/FITEE.2000069

Abstract: (NoC) is an infrastructure providing a communication platform to multiprocessor chips. Furthermore, the wormhole-switching method, which shares resources, was used to increase its efficiency; however, this can lead to congestion. Moreover, dealing with this congestion consumes more energy and correspondingly leads to increase in power consumption. Furthermore, consuming more power results in more heat and increases thermal fluctuations that lessen the life span of the infrastructures and, more importantly, the network’s performance. Given these complications, providing a method that controls congestion is a significant design challenge. In this paper, a is presented to enhance the NoC’s performance when facing congestion. To avoid congestion, the proposed algorithm employs the occupied input buffer and the total occupied buffers of the neighboring nodes along with the maximum possible path diversity with minimal path length from instant neighbors to the destination as the selection parameters. To enhance the path selection function, the uncertainty of the algorithm is used. As a result, the average delay, power consumption, and maximum delay are reduced by 14.88%, 7.98%, and 19.39%, respectively. Additionally, the proposed method enhances the throughput and the total number of packets received by 14.9% and 11.59%, respectively. To show the significance, the proposed algorithm is examined using transpose traffic patterns, and the average delay is improved by 15.3%. The average delay is reduced by 3.8% in TMPEG-4 (treble MPEG-4), 36.6% in QPIP (quadruplicate PIP), and 20.9% in TVOPD (treble VOPD).

Nanotechnology and Nanomedicine: A Promising Avenue for Lung Cancer Diagnosis and Therapy Review

Wei Yin, Feng Pan, Junjie Zhu, Junwu Xu, Diego Gonzalez-Rivas, Meinoshin Okumura, Zhiyong Tang, Yang Yang,

Engineering 2021, Volume 7, Issue 11,   Pages 1577-1585 doi: 10.1016/j.eng.2020.04.017

Abstract:

Lung cancer is a leading cause of cancer-related death worldwide, with a very poor overall five-year survival rate. The intrinsic limitations associated with the conventional diagnosis and therapeutic strategies used for lung cancer have motivated the development of nanotechnology and nanomedicine approaches, in order to improve early diagnosis rate and develop more effective and safer therapeutic options for lung cancer. Cancer nanomedicines aim to individualize drug delivery, diagnosis, and therapy by tailoring them to each patient's unique physiology and pathological features—on both the genomic and proteomic levels—and have attracted widespread attention in this field. Despite the successful application of nanomedicine techniques in lung cancer research, the clinical translation of nanomedicine approaches remains challenging due to the limited understanding of the interactions that occur between nanotechnology and biology, and the challenges posed by the toxicology, pharmacology, immunology, and large-scale manufacturing of nanoparticles. In this review, we highlight the progress and opportunities associated with nanomedicine use for lung cancer treatment and discuss the prospects of this field, together with the challenges associated with clinical translation.

Comprehensive strengthening mechanism of steel based on nano scale cementite precipitates

Fu Jie,Li Guangqiang,Yu Yueguang,Mao Xinping,Fang Keming

Strategic Study of CAE 2011, Volume 13, Issue 1,   Pages 31-42

Abstract:

This paper summarized the status of comprehensive strengthening mechanism of steel. By using chemical phase analysis, X-ray small-angle scattering, RTO and high-resolution TEM observation, the properties of nano-scale cementite precipitates in Ti micro-alloyed high strength weathering steels produced by thin slab continuous casting and rolling process were analyzed. Except nano-scale TiC, cementites precipitates less than 36 nm and high volume fraction were also found in Ti micro-alloyed high strength weathering steels.The volume fraction of cementite less than 36 nm is 4.4 times as much as that of TiC in the same size. Cementite with high volume fraction has stronger precipitation strengthening effect than that of nano-scale TiC, which can not be ignored.The precipitation strengthening contributions of nano-scale precipitates of different types and sizes should be calculated respectively according to the mechanisms of dislocation intersection and dislocation bypass, and then be added up with the contributions of solid solution strengthening and grain refinement strengthening.A formula for calculate the yield strength of low carbon steel is proposed, and the calculated yield strength considering the precipitation strengthening contributions of nano-scale precipitates and the comprehensive strengthening mechanism of steels matches the experimental results well. The calculated σs=630~676 MPa, while the examined σs=630~680 MPa. The reason for grain refinement strengthening can not directly plus dislocation strengthening and the performance form of phase transformation's influence on steel strength were debated.The applications for comprehensive strengthening theory were summarized, and several scientific questions for further study were put forward.

Design and analysis of carbon nanotube FET based quaternary full adders Article

Mohammad Hossein MOAIYERI,Shima SEDIGHIANI,Fazel SHARIFI,Keivan NAVI

Frontiers of Information Technology & Electronic Engineering 2016, Volume 17, Issue 10,   Pages 1056-1066 doi: 10.1631/FITEE.1500214

Abstract: CMOS binary logic is limited by short channel effects, power density, and interconnection restrictions. The effective solution is non-silicon multiple-valued logic (MVL) computing. This study presents two high-performance quaternary full adder cells based on carbon nanotube field effect transistors (CNTFETs). The proposed designs use the unique properties of CNTFETs such as achieving a desired threshold voltage by adjusting the carbon nanotube diameters and having the same mobility as p-type and n-type devices. The proposed circuits were simulated under various test conditions using the Synopsys HSPICE simulator with the 32 nm Stanford comprehensive CNTFET model. The proposed designs have on average 32% lower delay, 68% average power, 83% energy consumption, and 77% static power compared to current state-of-the-art quaternary full adders. Simulation results indicated that the proposed designs are robust against process, voltage, and temperature variations, and are noise tolerant.
