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.

Design of Hygroscope for Tongue Moisture

Jia Guixi,Pei Xiaona,Kang Yingpeng,Zhu Kai

Strategic Study of CAE 2007, Volume 9, Issue 4, Pages 41-44

Abstract:

In traditional Chinese medicine, tongue moisture plays an important role in tongue diagnosis. However, there are still some problems in conventional measurement. Therefore, a hygroscope, which uses digital humidity and temperature sensor, was developed to test tongue moisture based on mass transfer means. This paper presents its testing principle and the design method of its hardware and software. This hygroscope finds itself with some attractive features, such as portability, handy operation, low power consumption, etc. It has been proved that the standard deviation of this tester, only 2.9%, is better than that of other conventional instruments, and the tongue moisture could be measured rapidly and accurately.

Development Trends for China’s Instrumentation Engineering Science and Technology to 2035

Wang Xue and Zhang Li

Strategic Study of CAE 2017, Volume 19, Issue 1, Pages 103-107 doi: 10.15302/J-SSCAE-2017.01.015

Abstract:

Instrumentation is the fundamental technology and essential equipment for intelligent manufacturing, scientific research, environmental monitoring, healthcare, national defense construction, and so forth. As an important support toward achieving a national innovation strategy, instrumentation development determines the level of strategic new industries, which include the innovative information industry, high-end equipment-manufacturing industry, energy industry, materials industry, and so forth. This paper analyzes development trends of instrumentation engineering science and technology to 2035. Within the requirements of digital, intelligent, and networked instruments, key technologies and future trends are depicted for three main aspects: intelligent instrumentation, medical instruments, and micro-electro-mechanical systems (MEMS). Development strategies and suggestions for China’s instrumentation engineering science and technology to 2035 are also put forward.

Forseeing Trends of Development of Analytical Instruments

Jin Qinhan

Strategic Study of CAE 2001, Volume 3, Issue 1, Pages 85-88

Abstract:

Analytical instruments form an important part of scientific instruments section. Analytical instrument industry belongs to the information industry with high technology. The development of analytical instrument industry is one of the main promotion forces and basis for the development of modern science and technology, economy and society. The innovation in scientific instrumentation is by all means an innovation of science and technology. It should be considered as a strategy of the whole nation to speed up the development of scientific instruments. The main application area of analytical instruments has been moving towards the biomedical fields and analytical instrumentation itself is going towards miniaturization and with more intelligence. However, the precise instrumentation of high quality needed when the human challenges the two extremes of either time or space is definitely not negligible. Life, production, scientific research and social activities all need large quantities of such analytical instruments as on-line, noninvasive, nondestructive, in-situ, in-real-time and multidimensional instruments. The trend of widening the gop between the instrument industry at home and abroad must be taken into serious consideration. One of the main factors which influences the changing of such a situation most would be the change of the old idea on scientific instruments of all ranks including leaders, enterprisers as well as scientists and engineers.

A Predictive Instrument for Sensitive and Expedited Measurement of Ultra-Barrier Permeation Article

Jianfeng Wanyan, Kun Cao, Zhiping Chen, Yun Li, Chenxi Liu, Runqing Wu, Xiao-Dong Zhang, Rong Chen

Engineering 2021, Volume 7, Issue 10, Pages 1461-1470 doi: 10.1016/j.eng.2021.02.017

Abstract:

The reliable operation of flexible display devices poses a significant engineering challenge regarding the metrology of high barriers against water vapor. No reliable results have been reported in the range of 10^-6 g∙(m²∙d)^-1, and there is no standard ultra-barrier for calibration. To detect trace amount of water vapor permeation through an ultra-barrier with extremely high sensitivity and a greatly reduced test period, a predictive instrument was developed by integrating permeation models into high-sensitivity mass spectrometry measurement based on dynamic accumulation, detection, and evacuation of the permeant. Detection reliability was ensured by means of calibration using a standard polymer sample. After calibration, the lower detection limit for water vapor permeation is in the range of 10^-7 g∙(m²∙d)^-1, which satisfies the ultra-barrier requirement. Predictive permeation models were developed and evaluated using experimental data so that the steady-state permeation rate can be forecasted from non-steady-state results, thus enabling effective measurement of ultra-barrier permeation within a significantly shorter test period.
