China's Progress in Semiconductor Manufacturing Equipment
MARCH 2021 China’s Progress in Semiconductor Manufacturing Equipment Accelerants and Policy Implications CSET Policy Brief AUTHORS Will Hunt Saif M. Khan Dahlia Peterson Executive Summary China has a chip problem. It depends entirely on the United States and U.S. allies for access to advanced commercial semiconductors, which underpin all modern technologies, from smartphones to fighter jets to artificial intelligence. China’s current chip dependence allows the United States and its allies to control the export of advanced chips to Chinese state and private actors whose activities threaten human rights and international security. Chip dependence is also expensive: China currently depends on imports for most of the chips it consumes. China has therefore prioritized indigenizing advanced semiconductor manufacturing equipment (SME), which chip factories require to make leading-edge chips. But indigenizing advanced SME will be hard since Chinese firms have serious weaknesses in almost all SME sub-sectors, especially photolithography, metrology, and inspection. Meanwhile, the top global SME firms—based in the United States, Japan, and the Netherlands—enjoy wide moats of intellectual property and world- class teams of engineers, making it exceptionally difficult for newcomers to the SME industry to catch up to the leading edge. But for a country with China’s resources and political will, catching up in SME is not impossible. Whether China manages to close this gap will depend on its access to five technological accelerants: 1. Equipment components. Building advanced SME often requires access to a range of complex components, which SME firms often buy from third party suppliers and then assemble into finished SME. -
Journals PDF | Frontiers in Heat Pipes (FHP)
Frontiers in Heat Pipes (FHP), 5, 1 (2014) Global Digital Central DOI: 10.5098/fhp.5.1 ISSN: 2155-658X Frontiers in Heat Pipes Available at www.HeatPipeCentral.org HEAT PIPES: REVIEW, OPPORTUNITIES AND CHALLENGES Amir Faghri* Department of Mechanical Engineering, University of Connecticut, Storrs, CT 06269, U.S.A. ABSTRACT A detailed overview of heat pipes is presented in this paper, including a historical perspective, principles of operations, types of heat pipes, heat pipe performance characteristics, heat pipe limitations, heat pipe frozen startup and shutdown, heat pipe analysis and simulations, and various applications of heat pipes. Over the last several decades, several factors have contributed to a major transformation in heat pipe science and technology . The first major contribution was the development and advances of new heat pipes, such as loop heat pipes, micro and miniature heat pipes, and pulsating heat pipes. In addition, there are now many new commercial applications that have helped contribute to the recent interest in heat pipes, especially related to the fields of electronic cooling and energy. For example, several million heat pipes are now manufactured each month since all modern laptops use heat pipes for CPU cooling. Numerical modeling, analysis, and experimental simulation of heat pipes have also significantly progressed due to a much greater understanding of various physical phenomena in heat pipes, as well as advances in computational and experimental methodologies.

Nanotechnology and Picotechnology to Increase Tissue Growth: a Summary of in Vivo Studies
Nanotechnology and picotechnology to increase tissue growth: a summary of in vivo studies Ece Alpaslan1 and Thomas J Webster1,2 Author information ► Copyright and License information ► Go to: Abstract The aim of tissue engineering is to develop functional substitutes for damaged tissues or malfunctioning organs. Since only nanomaterials can mimic the surface properties (ie, roughness) of natural tissues and have tunable properties (such as mechanical, magnetic, electrical, optical, and other properties), they are good candidates for increasing tissue growth, minimizing inflammation, and inhibiting infection. Recently, the use of nanomaterials in various tissue engineering applications has demonstrated improved tissue growth compared to what has been achieved until today with our conventional micron structured materials. This short report paper will summarize some of the more relevant advancements nanomaterials have made in regenerative medicine, specifically improving bone and bladder tissue growth. Moreover, this short report paper will also address the continued potential risks and toxicity concerns, which need to be accurately addressed by the use of nanomaterials. Lastly, this paper will emphasize a new field, picotechnology, in which researchers are altering electron distributions around atoms to promote surface energy to achieve similar increased tissue growth, decreased inflammation, and inhibited infection without potential nanomaterial toxicity concerns. Keywords: nanomaterials, tissue engineering, toxicity Go to: Introduction Bone tissue and other organ dysfunction can be provoked by poor eating habits, stress, age-related diseases such as osteoarthritis or osteoporosis, as well as accidents.1 To date, common procedures to restore or enhance life expectancy involve medical device insertion or organ transplantation.1 However, due to the low number of donors and its high cost, organ transplantation is limited. -
Introducing Nanoengineering and Nanotechnology to the First Year Students Through an Interactive Seminar Course
Introducing nanoengineering and nanotechnology to the first year students through an interactive seminar course Hassan Raza1, Tehseen Z. Raza2 1 Department of Electrical and Computer Engineering, University of Iowa, Iowa City, Iowa 52242, USA [email protected] 2 Department of Physics and Astronomy, University of Iowa, Iowa City, Iowa 52242, USA [email protected] Abstract: We report a first year seminar course on nanoengineering, which provides a unique opportunity to get exposed to the bottom-up approach and novel nanotechnology applications in an informal small class setting early in the undergraduate engineering education. Our objective is not only to introduce the fundamentals and applications of nanoengineering but also the issues related to ethics, environmental and societal impact of nanotechnology used in engineering. To make the course more interactive, laboratory tours for microfabrication facility, microscopy facility, and nanoscale laboratory at the University of Iowa are included, which inculcate the practical feel of the technology. The course also involves active student participation through weekly student presentations, highlighting topics of interest to this field, with the incentive of “nano is everywhere!” Final term papers submitted by the students involve a rigorous technology analysis through various perspectives. Furthermore, a student based peer review process is developed which helps them to improve technical writing skills, as well as address the ethical issues of academic honesty while reviewing and getting introduced to a new aspect of the area presented by their colleagues. Based on the chosen paper topics and student ratings, the student seemed motivated to learn about the novel area introduced to them through theoretical, computational and experimental aspects of the bottom-up approach. -

CHAPTER 11 Introduction The increase of world population is a challenge itself for world resources. The sustainability of food supplies, energy resources, and the environment are being questioned by analysts, while climate change just adds more pressure to the equation. The life expectancy of the world as a whole is rising while the fertility rate is declining. This will create a challenge in health care for the ageing population (Gavrilov and Heuveline, 2003). The United States alone will have 20% of the population over the age of 65 by 2050. In contrast, Europe will see rates close to 30% while Japan will arise to almost 40%, as summarized in Table 1.1. It is anticipated that in the near future, specialized health-care services will be in higher demand due to this increase. This demand will be characterized by medical resources not only to attend to this segment of the population, but also to keep them active as well. Therefore, the monitoring of physiological responses as well as specialized drug or other therapy delivery applications will be needed for portable, wearable, or implantable biomedical autonomous devices. In addition, wireless communication promises new medical applications such as the use of wireless body sensor networks for health monitoring (Jovanov et al., 2005; Hao and Foster, 2008; Varshney, 2007). These biomedical devices, however, come with their own issues, mainly power source challenges. Batteries are commonly used to energize most of these applications, but they have a finite lifetime.

Academic Editors: Prabir Patra and Ashish Aphale Received: 9 September 2015 / Accepted: 14 October 2015 / Published: 23 November 2015 Abstract: Nanotechnology is becoming increasingly important in the field of (bio)sensors. The performance and sensitivity of biosensors is greatly improved with the integration of nanomaterials into their construction. Since its first discovery, fullerene-C60 has been the object of extensive research. Its unique and favorable characteristics of easy chemical modification, conductivity, and electrochemical properties has led to its tremendous use in (bio)sensor applications. This paper provides a concise review of advances in fullerene-C60 research and its use as a nanomaterial for the development of biosensors. We examine the research work reported in the literature on the synthesis, functionalization, approaches to nanostructuring electrodes with fullerene, and outline some of the exciting applications in the field of (bio)sensing. Keywords: nanotechnology; nanostructures; nano-bio hybrids; fullerene-biomolecule; biosensors 1. Introduction Bio-nanotechnology is a new emerging field of nanotechnology and combines knowledge from engineering, physics, and molecular engineering with biology, chemistry, and biotechnology aimed at the development of novel devices, such as biosensors, nanomedicines, and bio-photonics [1]. -

D. Cremer, CHEM 6342, Nanotechnology - Fundamentals and Applications 1 CHEM 6342 Nanotechnology – Fundamentals and Applications Class location: TBD Lectures, time and location: TBD Lab times and location: TBD Instructor: Dieter Cremer, 325 FOSC, ext 8-1300, [email protected] http://smu.edu/catco/ Office Hours: By appointment Units: 3 Grading: ABC Letter Grade Class number TBD 1. Rationale: Nanotechnology (NT) is a rather young discipline, which came up in the nineties. Nevertheless, NT has gained so much importance within the last years that universities at all rankings have introduced or are going to introduce NT teaching programs. Predictions say that NT will change our lives and society more than computer technology and electricity have done together. The course will provide an overview over NT. It will show that the nano regime is so different from other regimes because both classical and quantum effects can be active thus leading to unique properties of nano devices. NT is a highly interdisciplinary science, which will be reflected in the course by making reference to chemistry, physics, biology, pharmacy, and engineering. Applications of NT, as they are already in use today or as they are planned for the future, will be discussed. 2. Course Recommendations: The course is designed to reach all graduate students who had have an education in chemistry, physics, engineering or biology. It does not require special knowledge in mathematics or theoretical physics. The course contents will be presented in self-sustained modules, which make it possible to follow the course without special knowledge. The course will prepare for the interdisciplinary work in NT. -

The vacuum chamber of this 100 TeV, 100 km collider, will have to cope with unprecedented levels of synchrotron radiation linear power for proton colliders, 160 times higher than in the LHC for baseline parameters, releasing consequently much larger amounts of gas into the system. At the same time, it will be dealing with a tighter magnet aperture. In order to reach a good vacuum level, it has been necessary to find solutions beyond the particle colliders’ state of art. This paper proposes a design of a novel beam screen, the element responsible for absorbing the emitted power. It is intended to overcome the drawbacks derived from the stronger synchrotron radiation while allowing at the same time a good beam quality. DOI: 10.1103/PhysRevAccelBeams.23.033201 I.
