These slides use concepts from my (Jeff Funk) course entitled analyzing hi-tech opportunities to analyze how the economic feasibility of carbon nanotubes is becoming better through developing new forms of carbon nanotubes, new methods of synthesis, and increasing the scale of production equipment. New forms of carbon nanotubes continue to be developed; new ones include carbon nanobuds, doped carbon nanotubes, and graphenated carbon nanotubes, each of which includes many variations. The large number of variations suggests that carbon nanotubes will likely experience improvements in performance and the number of applications will continue to grow.

Study on Carbon Nanotube Based Flexible Electronics.pptxesfar1
Carbon nanotubes (CNTs) have emerged as a revolutionary material in the field of flexible electronics, offering exceptional mechanical, electrical, and thermal properties. These cylindrical structures, composed of rolled-up graphene sheets, exhibit remarkable strength, flexibility, and electrical conductivity, making them ideal candidates for the development of next-generation electronic devices.
The unique properties of CNTs stem from their nanoscale dimensions and the arrangement of carbon atoms, which result in exceptional electrical conductivity. CNTs can conduct electricity thousands of times better than traditional materials like copper while maintaining their structural integrity. This remarkable conductivity, coupled with their flexibility, opens up a world of possibilities for creating highly efficient and adaptable electronic devices. Flexible electronics, which involve the integration of electronic components onto flexible substrates, have garnered significant attention due to their potential for revolutionizing various industries. By utilizing CNTs, researchers have been able to overcome the limitations of traditional rigid electronic materials, such as silicon. CNT-based flexible electronics offer improved mechanical flexibility, allowing them to conform to complex and irregular surfaces, withstand bending and stretching, and even be incorporated into wearable devices or electronic textiles.
This slide is based on a study of CNT based Flexible Electronics.
The goal of presentation on carbon nanotubes(CNTs) is to briefly introduce to this growing novel area of material science. I feel it is important to create an awareness of the nanosciences and their potential applications in the future of nanotechnology. The typical question of “when are we going to use this stuff”,? If some one ask such a question, then they are also responsible for finding answers to satisfy their curiosity. In the case of carbon nanotubes and their properties, hopefully this paper will help them in their quest. This ppt is focussed on the discovery, synthesis,growth processes, properties and the latest research advances of carbon nanotubes developed over the past 12 years. Because of their remarkable electronic and mechanical properties, carbon nanotubes are unique and exciting. The field has been developed rapidly, and the number of publications per year is increasing almost exponentially. Various technological applications are likely to arise using nanotubes for fabrication of flat panel displays, gas storage devices, toxic gas sensors, Li+ batteries, robust and light weight composites, conducting paints, electronic nanodevices etc. Further experimental and theoretical research is still necessary so these novel technologies will become a reality in the early 21 century.
Carbon has four electrons in its outer valence shell; the ground state configuration is 2s2 2p2. Diamond and graphite are considered as two natural crystalline forms of pure carbon. In diamond, carbon atoms exhibit sp3 hybridization, in which four bonds are directed toward the corners of a regular tetrahedron. The resulting three-dimensional network (diamond) is extremely rigid, which is one reason for its hardness. The bond length between sp3 carbons (e.g., diamond) is 1.56 ˚A. In graphite, sp2 hybridization occurs, in which each atom is connected evenly to three carbons (120◦) in their plane, and a weak π bond is present in the z axis. The C–C sp2 bond length is 1.42 ˚A. The sp2 set forms the hexagonal (honeycomb) lattice typical of a sheet of graphite.
Metals, however much we need it or admire it , the drawbacks of it has to be considered.( high density, susceptibility to corrosion,availability etc)
Instead planes of carbon fibre composites can be made without using a tiny scrap of metal, if only we can alter its conductivity issues. that is addressed by a research paper , on the basis of which my ppt is based.
These slides use concepts from my (Jeff Funk) course entitled analyzing hi-tech opportunities to analyze improvements in the economic feasibility of carbon nanotubes (CNTs) for transparent electrodes and flywheels. Improvements in the transparency and cost of CNTs are enabling CNTs to replace indium tin oxide in applications such as solar cells and displays. Second, as the cost of CNTs falls through improvements in processes and increases in the scale of equipment, they will become economically feasible for flywheels. Since the energy storage density of flywheels is directly proportional to the strength to weight ration of the flywheel material, CNTs (and graphene) have potential energy storage densities that are ten times the current energy storage densities of carbon fiber-based flywheels and Li-ion batteries. This means that carbon nanotubes are an important tool in the battle against fossil-fuel dependency and global warming.

CNTFET Based Analog and Digital Circuit Designing: A ReviewIJMERJOURNAL
ABSTRACT: Silicon has been a material of choice for the last many decades and more than 95% of electronics devices are from silicon. However, silicon has reached to its saturation level and extracting more and more performance is difficult and costly now. A new material which has a potential to replace Si and can extend the scalability of devices below 22 nm is the carbon nanotube (CNT). CNT is a wonderful material possesses unique properties that make it a promising future material. CNT based field effect transistor (Cntfet) is a promising basic building block to complement the existing silicon based MOSFET and can result in the extension of the validity of Moore's law further. CNTFT has been used extensively in realizing electronics circuits. This paper presents the state of the art literature related to carbon nanotubes, carbon nanotube field effect transistors and CNTFET based circuit designing. A review of Cntfet based analog and digital circuits has been presented. It has been observed that the use of CNTFET has improved the performance of both analog and digital circuits. The work will be very useful to the people working in the field of CNT based analog and digital circuit designing.
The "Unproductive Bubble:" Unprofitable startups, small markets for new digit...Jeffrey Funk
This article will show that the current bubble has produced few profitable startups and involved few if any new digital technologies, nor technologies involving recent scientific advances, and thus it is unlikely that much that is productive will be left once the dust settles. There is a growth in old technologies such as e-commerce but little in new technologies such as AI. The startup losses are also much larger than in the past suggesting that fewer of today’s startups will still exist in a few years than those of 20 years ago.
Commercialization of Science: What has changed and what can be done to revit...Jeffrey Funk
This paper several changes that I believe may have reduced America’s ability to develop science-based technologies. I make no claims about the completeness. I begin with the growth of university research and then cover several changes it engendered, including an obsession with papers, hyper-specialization of researchers, and huge bureaucracies, also using the words of Nobel Laureates and other scientists to make my points.
2000, 2008, 2022: It is hard to avoid the parallels How Big Will the 2022 S...Jeffrey Funk
These slides summarize the recent share price declines for new startups, declines that are driven by huge annual and cumulative losses and it contrasts today's bubble with those of 2000 and 2008. It shows that today's bubble involves bigger startup losses than those of the 2000 bubble and that the markets of new technologies have not grown to the extent that those of past decades did. Many hedge funds, VCs, and pension funds are heavily invested in these startups. Some of them are also highly leveraged.
The Slow Growth of AI: The State of AI and Its ApplicationsJeffrey Funk
The failure of IBM Watson, disappointments of self-driving vehicles, slow diffusion of medical imaging, small markets for AI software, and scorching criticisms of Google’s research papers provide evidence for hype and disappointment in AI, which is consistent with negative social impact of Big Data and AI algorithms. There are some successes, but they are much smaller than the predictions, with virtual applications (advertising, news, retail sales, finance and e-commerce) having the largest success, building from previous Big Data usage in the past. Looking forward, AI will augment not replace workers just as past technologies did on farms, factories, and offices. Robotic process automation and natural language processing are likely to play important roles in this augmentation with RPA automating repetitive work, natural language processing summarizing information, and RPA also putting the information in the right bins for engineers, accountants, researchers, journalists, and lawyers. Big challenges include reductions in training time depending on faster computers, exponentially rising demands on computers for high accuracies in image recognition, a slowdown in supercomputer improvements, datasets riddled with errors, and reproducibility problems.

Smaller than expected markets, money-losing startups, failure of Watson, slow-diffusion of self-driving vehicles and medical imaging, and scorching criticisms of Google’s research papers are some of the examples used to characterize the hype of AI. There are some successes, but they are much smaller than the predictions, with advertising, news, and e-commerce having the biggest success stories. Looking forward, #AI will augment not replace workers just as past technologies did on farms, factories, and offices. Robotic process automation and natural language processing are likely to play important roles in this augmentation with #RPA automating repetitive work, natural language processing categorizing information, and RPA also putting the information in the right bins for engineers, accountants, researchers, journalists, and lawyers. The big challenges include exponentially rising demands on computers for high accuracies in images, a slowdown in supercomputer improvements, datasets riddled with errors, and reproducibility problems.

The Troubled Future of Startups and Innovation: Webinar for London FuturistsJeffrey Funk
These slides show how the most successful startups of today (Unicorns) are not doing as well as the most successful of 20 to 50 years ago. Today's startups are doing worse in terms of time to profitability and time to top 100 market capitalization status. Only one Unicorn founded since 2000 has achieved top 100 market capitalization status while six, nine, and eight from the 70s, 80s, and 90s did so. It is also unlikely that few or any of today's Unicorns will achieve this status because their market capitalizations are too low, share prices increases since IPO are too small, and profits remain elusive. Only 14 of 45 had share price increases greater than the Nasdaq and only 6 of 45 had profits in 2019. The reasons for the worse performance of today's Unicorns than those of 20 to 50 years ago include no breakthrough technologies, hyper-growth strategies, and the targeting of regulated industries. The slides conclude with speculations on why few breakthrough technologies, including science-based technologies from universities are emerging. We need to think back to the division of labor that existed a half a century ago.
Where are the Next Googles and Amazons? They should be here by nowJeffrey Funk
Great startups aren’t being founded like they were in the 1970s (Microsoft, Apple, Oracle, Genentech, Home Depot, EMC), 1980s (Cisco, Dell, Adobe, Qualcomm, Amgen, Gilead Sciences), and 1990s (Amazon, Google, Netflix, Salesforce.com, PayPal). All of these startups reached the top 100 for market capitalization, but Facebook is the only startup founded since 2000 which has entered the top 100. Tesla and Uber are often discussed as highly successful but they have many times higher cumulative losses than did Amazon at its time of peak losses and neither has had a profitable year despite being older than Amazon was when it achieved profits. Furthermore, few of the recent Unicorn IPOs have experienced shareprice increases greater than those of the Nasdaq (14 of 45), only 3 of these 14 have profits, and only six of them have a
market capitalization over $30 (Zoom), $20 (Square), and $10 billion (Twilio, DocuSign, Okta). America’s venture capital system isn’t working as well as it once did, and the coronavirus will make things worse before the VC system gets better.
Start-up losses are mounting and innovation is slowing, but venture capitalists, entrepreneurs, consultants, university researchers, and business schools are hyping new technologies more than ever before. This hype is facilitated by changes in online media, including the rise of social media. This paper describes how the professional incentives of experts and the changes in online media have increased hype and how this hype makes it harder for policy makers, managers, scientists, engineers, professors, and students to understand new technologies and make good decisions. We need less hype and more level-headed economic analysis and this paper describes how this economic analysis can be done.

Irrational Exuberance: A Tech Crash is ComingJeffrey Funk
These slides apply Nobel Laureate Robert Schiller's concept of irrational exuberance (and a book) title to the current speculative bubble of 2019. Over investments in startups and a lack of profitability in them are finally starting to catch up with the venture capital industry and the tech sector that relies on it. Investments by US venture capitalists have risen about six times since 2001 causing the total invested in 2018 to exceed by 40% the peak of 2000, the last big year of the dotcom bubble. But the number of IPOs has never returned to the peak years of 1993 to 2000; only about 250 were carried out between 2015 and 2017 vs. about 1,200 between 1995 and 1997.
The reason is simple: startups are taking longer to go public because they are not profitable. Consider the data. The median time to IPO has risen from 2.8 years in 1998 to 7.7 years in 2016 and the ones going public are less profitable than they were in the past. Although only 22% of startups going public in 1980 were unprofitable, 82% were unprofitable in 2018. The same high percentages of unprofitability have only been achieved twice before, in 1998 and 1999 right before the dotcom bubble burst. Furthermore, startups that have recently done high profile IPOs such as Snap, Dropbox, Blue Apron, Fitbit, Trivago, Box, and Cloudera are still not profitable.
Ride Sharing, Congestion, and the Need for Real SharingJeffrey Funk
Current ride sharing services are not financially sustainable. Although they provide more convenience than do taxi services, they are experiencing massive losses because they have the same cost structure as do taxis and thus must compete through subsidies and lower wages. After all, they use the same vehicles, roads, and drivers, and only GPS algorithms and phones are new.
They also increase congestion. Just as more private vehicles or taxis on the road will increase congestion, more ride sharing vehicles also increase congestion.
These slides describe new ways to use the technologies of ride sharing to reduce congestion along with costs while at the same time keeping travel time low. This can be done through changing public transportation systems or allowing private companies to offer competing services. For instance, current bus services, whether they are private or public, need to use the algorithms, GPS, phones and other technologies of ride sharing to revise routes, schedules and the premises that currently underpin public transportation. There is no reason a bus should be certain size, stop every 200 meters, or follow the same route all day. Algorithms and phones enable new types of routes in which designers simultaneously minimize time travel and maximize number of passengers transported per vehicle.hour.
Using the percent of top managers in IPOs (initial public offering) as a proxy for an industry’s/technology’s scientific intensity, this paper shows that the percentage of IPOs and of venture capital financing for science-based technologies has been declining for decades. Second, the percentage of PhDs among the top managers in science intensive industries is also declining, suggesting that their scientific intensities are falling. Third, the age of these top managers rose during the same period suggesting that the importance of experiential knowledge has increased even as the importance of PhDs and thus educational knowledge has decreased. Fourth, the numbers of IPOs and of venture capital funding are not increasing for newer science-based industries such as superconductors, solar cells, nanotechnology, and GMOs. Fifth, there are extreme diseconomies of scale in the universities that produce the PhD-holding top managers, suggesting that universities are far less effective at doing research than are companies. These results provide a new understanding of science and technology, and they offer new prescriptions for reversing slowing productivity growth.
This paper addresses the types of knowledge that are needed in entrepreneurial firms using a unique data base of executives and directors for all IPOs filed between 1990 and 2010. Using highest educational degrees as a proxy for educational knowledge, it shows that 85% of those with PhDs are concentrated in the life sciences and ICT (information and communication technology) industries and second, that those in the ICT industries are concentrated at lower layers in a “digital stack” of industries, ranging from semiconductors and other electronics at the bottom layer to computing and Internet infrastructure at the middle layer and Internet content, commerce, and services in the top layer. Third, industries with fewer PhDs have more bachelor’s and MBA degrees suggesting that PhDs are being replaced by them and not M.S. degrees. Fourth, age is higher for industries with the most PhDs thus suggesting a greater need for experiential knowledge in industries with greater needs for educational knowledge. Fifth, the number of Nobel Prizes tracks industries with high fractions of PhDs.
beyond patents:scholars of innovation use patenting as an indicator of innova...Jeffrey Funk
This paper discusses the problems with using patents as a measure of innovation and papers as a measure of science. It also uses data to show the problems. for example, the number of patent applications and awards have grown by six times since 1984 while productivity growth has slowed.
These slides discuss how to put context back into learning. Farm and other work at home once provided a context for learning, but this context has become much weaker as work at home as mostly disappeared Students once learned mostly from parents because they worked on farms, fixed things at home, and prepared meals. These activities provided a "context" for school learning, a context that has been mostly lost. These slides discuss how this context can be put back into learning and the implications for the types of people best suited for teaching and the way to train them.
Technology Change, Creative Destruction, and Economic FeasibiltyJeffrey Funk
After showing that the costs of most electronic products are from electronic components, these slides show how the iPhone and iPad became economically feasible through improvements in microprocessors, flash memory, and displays.
These slides show that the demand for most professions is growing steadily in spite of continued improvements in productivity enhancing tools for them. They also show that AI will have a largely incremental effect on the professions, in combination with Moore's Law, cloud computing, and Big Data. They do this accounting, legal, architects, journalists, and engineers.
Solow's Computer Paradox and the Impact of AIJeffrey Funk
These slides show why IT has not delivered large improvements in productivity and why new forms of IT like AI will also not deliver large improvements, except in selected sectors. The main reason is that the improvements in AI are over-hyped and because most sectors do not have large inefficiencies in the organization of people, machinery, and materials.
What does innovation today tell us about tomorrow?Jeffrey Funk
This paper was published in Issues in Science and Technology. It distinguished between the Silicon Valley and science-based process of technology change. It shows that more new products and services are emerging from the latter than the former.
Creative destrution, Economic Feasibility, and Creative Destruction: The Case...Jeffrey Funk
This paper shows how new forms of electronic products and services such as smart phones, tablet computers and ride sharing become economically feasible and thus candidates for commercialization and creative destruction as improvements in standard electronic components such as microprocessors, memory, and displays occur. Unlike the predominant viewpoint in which commercialization is reached as advances in science facilitate design changes that enable improvements in performance and cost, most new forms of electronic products and services are not invented in a scientific sense and the cost and performance of them are primarily driven by improvements in standard components. They become candidates for commercialization as the cost and performance of standard components reach the levels necessary for the final products and services to have the required levels of performance and cost. This suggests that when managers, policy makers, engineers, and entrepreneurs consider the choice and timing of commercializing new electronic products and services, they should understand the composition of new technologies, the impact of components on a technology's cost, performance and design, and the rates of improvement in the components.

Unveiling the Secrets How Does Generative AI Work.pdfSam H
At its core, generative artificial intelligence relies on the concept of generative models, which serve as engines that churn out entirely new data resembling their training data. It is like a sculptor who has studied so many forms found in nature and then uses this knowledge to create sculptures from his imagination that have never been seen before anywhere else. If taken to cyberspace, gans work almost the same way.

* Lesser number of surrounding atoms implies damage site is getting smaller / healing.
Self-Healing Properties of CNTs
by Heat treatment
34. • When a vacancy (defect) happens in the nanotube, the three neighbor atoms can
create new bonding. A new bonding takes about 200 femtoseconds* after atoms are
excited1.
*A femtosecond is the SI unit of time equal to 10−15 of a second
