LabVIEW controlled atomic force microscopy for remote nanoelectronics laboratory

TL;DR: In this article, the design and implementation of a remotely controlled online (internet-based) experiment on thin film characterization for nanotechnology laboratory using atomic force microscope (AFM) is reported.
Abstract: Design and implementation of a remotely controlled online (internet-based) experiment on thin film characterization for nanotechnology laboratory using atomic force microscope (AFM) is reported. Based on a commercially available low-cost AFM (Model NanoSurf EasyScan2) and National Instruments (NI) LabVIEW graphical programming environment, we have developed the remote-controlled AFM measurement system. The system is available online for use by the geographically distributed students to share and run experiments via standard web browsers. The infrastructure for the nanoelectronics laboratory is described and applications of this infrastructure to nanoelectronics education are discussed. Students and researchers could benefit by sharing the AFM through internet.

TL;DR: The Virtual Labs project addresses the issue of lack of good lab facilities, as well as trained teachers, by making remote experimentation possible by developing a novel methodology for field trials, outreach, and quality control.
Abstract: The lack of good and up-to-date lab experiments form a major impediment in the domain of engineering education. Often, the lab experiments are outdated. The Virtual Labs project addresses the issue of lack of good lab facilities, as well as trained teachers, by making remote experimentation possible. The pedagogy is student-centric. The Virtual Labs project has also developed a novel methodology for field trials, outreach, and quality control. Virtual Labs also provide tremendous cost advantage. The Virtual Labs project is a wonderful example of an open educational resource developed by a multiinstitution multidiscipline project team. Over 100000 students are currently using the online labs under the Virtual Labs project. Many of these labs are being accessed outside the regular lab hours.

TL;DR: An optical microscope that can be operated via the internet using most of the internet and networking capable devices including laptops and desktop computers, currently being used to perform thin film characterization experiments in microelectronics laboratory.
Abstract: We have engineered an optical microscope that can be operated via the internet using most of the internet and networking capable devices including laptops and desktop computers. The system offers a user the ability to conduct visual inspection of samples, microelectronic devices and manipulation experiments in the field of biology. The remote controlled microscope is programmed to perform acquisition of images. The instrument is currently being used to perform thin film characterization experiments in microelectronics laboratory. Such a system may find a wide range of new applications for science experiments.

TL;DR: A novel environment is described that provides 24-h-a-day access to a Web-based lab for the remote control of different didactic setups and the control of an inverted pendulum is used to demonstrate the use of such an environment.
Abstract: In this paper, a novel environment is described that provides 24-h-a-day access to a Web-based lab for the remote control of different didactic setups. The control of an inverted pendulum is used to demonstrate the use of such an environment. The main attributes of this Web-based lab are: 1) the on-line interactivity with the didactic setup, 2) the possibility of defining different experiments by using parameter files, and 3) the open architecture of the environment which allows easy development of new experiments with other didactic setups. The structure of this Web-based lab not only provides students with quantitative information feedback but also allows visual supervision. Now, a remote-controlled camera plays an important role within a remote experimentation environment with mobile parts. Students can handle the camera on-line, just as they can control the didactic setup over the Internet.

TL;DR: This paper is on the development of an educational tool, based on freeware, for the introduction of various Web-related aspects of remote instrumentation, with an important ingredient for handling multiple clients through a scheduling strategy that uses semaphores.
Abstract: With the growth of the Internet, an interesting possibility is that of performing research, development, and collaborative experimentation unlimited by physical location. The focus of this paper is on the development of an educational tool, based on freeware, for the introduction of various Web-related aspects of remote instrumentation. An important ingredient of the system is a mechanism for handling multiple clients through a scheduling strategy that uses semaphores. Other features include provisions for multiple-instrument access and output of the data acquired in textual and graphical forms. The approach is cost-effective, and the solution is suitable for a variety of platforms. Experiments using two instruments, namely a digital multimeter and a thermocouple unit, are reported.

TL;DR: This work describes a library of online courseware utilizing Java applets developed for microelectronics education to provide an online learning environment that supplements resident instruction.
Abstract: This work describes a library of online courseware utilizing Java applets developed for microelectronics education. The objective is to provide an online learning environment that supplements resident instruction. Java applets are utilized to interactively demonstrate principles, provide design tools, and allow students to test their knowledge via online quizzes. The course material and Java applets are included on the CD-ROM.

TL;DR: This paper discusses the hybrid time scheduling scheme for conducting experiments in an online remotely-triggered laboratory and some of its drawbacks and possible solution are presented.
Abstract: Remote Engineering is a current trend in engineering and science, aiming to allow and organize a shared use of equipment and resources. In this paper, we discuss the hybrid time scheduling scheme for conducting experiments in an online remotely-triggered laboratory. The scheme has been implemented in the NETLab online laboratory management system. Some of its drawbacks and possible solution are presented.
