Scientists fold the Smallest Microchips ever from Graphene

Published

on

New developments from physicists from the University of Sussex could lead to faster electronic gadgets. The physicists have created tiny microchip-like objects using ‘nano-origami.’ They foresee phones as well as computers operating many thousand times faster.

The researchers worked with 2D materials, including graphene. They used structural defects within the materials to build the microchips.

These defects affect the properties of the materials, both nano-mechanical and electronic.

The researchers pinpointed the effects of defects like grain boundaries, collapsed wrinkles, and folded wrinkles using Raman mapping and atomic force microscopy.

Graphene acts as a transistor when some distortions are folded into graphene. Transistors are the basic ingredient of electronics. When a graphene strip is folded like that it acts like a microchip.

The graphene strip in question is around 100 times tinier than normal microchips.

Lead researcher Dr. Manoj Tripathi explains the mechanism: “Instead of having to add foreign materials into a device, we’ve shown we can create structures from graphene and other 2D materials simply by adding deliberate kinks into the structure. By making this sort of corrugation we can create a smart electronic component like a transistor or a logic gate.”

The technique relies on Moore’s Law, a law which stipulates that the total sum of transistors within an integrated circuit doubles every two years.

Academics and leaders in the industry have warned that Moore’s law may not necessarily apply for transistors similar in size to silicon chips.

Graphene is a material that provides a possible alternative to silicon and can help to conserve Moore’s law. The researchers are the first to create a microchip using folded graphene.

Said Professor Alan Dalton: “We’re mechanically creating kinks in a layer of graphene. It’s a bit like nano-origami. Using these nanomaterials will make our computer chips smaller and faster. It is absolutely critical that this happens as computer manufacturers are now at the limit of what they can do with traditional semiconducting technology. Ultimately, this will make our computers and phones thousands of times faster in the future.”

“This kind of technology – ‘straintronics’ using nanomaterials as opposed to electronics – allows space for more chips inside any device. Everything we want to do with computers, to speed them up, can be done by crinkling graphene like this.”

Now the researchers are hopeful for further developments in sustainable technology because this process does not require additional materials and can go on at room temperature. It saves energy.

In a groundbreaking advancement, researchers at the University of Jyväskylä, Finland, have developed a model that enables computers to interpret and understand human emotions using principles of mathematical psychology. This innovative approach promises to revolutionize the way machines interact with humans, enhancing user experience across various applications.

The model, detailed in a recent publication, leverages complex mathematical algorithms to decode emotional cues from human interactions. By analyzing patterns in speech, text, and physiological responses, the system can identify and respond to a range of emotions, from happiness and excitement to sadness and frustration. This breakthrough addresses a long-standing challenge in the field of human-computer interaction: the ability of machines to understand and appropriately respond to the nuanced emotional states of users.

Dr. Mikko Koskinen, one of the lead researchers, explained that the model is rooted in psychological theories that describe how humans process emotions. “By applying mathematical frameworks to these psychological theories, we’ve created a system that can more accurately interpret emotional signals,” Koskinen said. The team utilized data from extensive psychological studies and collaborated with experts in both psychology and computer science to refine their approach.

The implications of this research are vast. For instance, in the healthcare sector, emotionally intelligent machines could provide better support to patients with mental health issues. An emotionally aware virtual assistant could recognize signs of distress or anxiety and offer appropriate interventions or notify healthcare professionals, thereby improving patient outcomes.

Moreover, the technology could enhance customer service experiences. Businesses could deploy emotionally perceptive chatbots that adapt their responses based on the customer’s emotional state, leading to more satisfying interactions and higher levels of customer satisfaction. This would be particularly beneficial in high-stress situations, such as technical support or financial services, where understanding a customer’s emotional state can significantly impact the resolution process.

The development of emotionally intelligent machines also raises important ethical and privacy considerations. Ensuring that such systems respect user privacy and operate transparently is crucial. Organizations like the European Union Agency for Cybersecurity (ENISA) emphasize the need for robust data protection measures to safeguard the sensitive information these systems may handle.

Additionally, the integration of this technology into everyday devices will require collaboration between industry stakeholders and regulatory bodies. Entities such as the International Organization for Standardization (ISO) play a pivotal role in setting the standards that ensure the safe and effective deployment of new technologies.

As this technology advances, it is essential to maintain a dialogue about its implications. Researchers, industry leaders, and policymakers must work together to navigate the complexities of implementing emotionally intelligent systems in a way that benefits society while mitigating potential risks.

In conclusion, the University of Jyväskylä’s innovative model marks a significant step forward in the field of human-computer interaction. By bridging the gap between psychological theory and mathematical modeling, this research opens up new possibilities for creating machines that truly understand and respond to human emotions, paving the way for more empathetic and effective technological solutions.

Navigating the Crossroads of Technology and Education: A Delicate Balance

Published

By

The interplay between technology and education has always been a topic of keen interest and intense debate among educators, policymakers, and parents alike. The advent of the COVID-19 pandemic and the consequent shift towards remote learning have magnified this issue, bringing to the forefront the critical need to evaluate the role of technology in our educational systems. Drawing insights from a recent editorial by The Seattle Times, this article delves into the complexities of integrating technology into education, examining both its promises and pitfalls.

The pandemic-era transition to remote learning highlighted a stark reality: the necessity of human connection in the educational process. According to a New York Times investigation, learning through a computer screen during the pandemic had as detrimental an impact on student achievement as growing up in poverty. This finding underscores the critical importance of reevaluating our approach to technology in education, not as a wholesale replacement for traditional learning environments but as a complement to them.

However, the issue extends beyond the realm of remote learning. The ubiquitous presence of smartphones in classrooms, even post-pandemic, poses a significant challenge to maintaining focus and fostering meaningful human connections among students. Attempts by Seattle Public Schools to address this challenge by filing a lawsuit against social media companies, though well-intentioned, might not be the most direct or effective approach. Instead, smaller districts like Reardan-Edwall in Eastern Washington have seen success with more straightforward policies, such as banning cellphones for younger students during school hours. This policy has led to a decrease in bullying and a resurgence of human conversations within the school environment, according to Eric Sobotta, superintendent of Reardan-Edwall schools.

The conversation around technology in education is not new. Prior to the pandemic, concerns were already being raised about the efficacy of online learning programs, especially those designed for credit recovery in high schools. The London School of Economics has found that even the mere presence of a phone in class can impair student achievement, particularly among those already facing academic challenges.

In response to these challenges, some states, including California, Tennessee, and Florida, are taking proactive steps to address the impact of technology on education at the state level. These measures range from restricting cellphone use in schools to integrating artificial intelligence in classrooms as a tool to enhance, rather than replace, human inquiry. Washington State’s Superintendent Chris Reykdal’s recent guidance on the use of artificial intelligence in education reflects a growing recognition of the need to thoughtfully integrate technology into the learning process.

The key to navigating the complex relationship between technology and education lies in finding a delicate balance. It is not about eschewing technology altogether but about harnessing its potential to enhance educational outcomes while mitigating its distractions and potential harms. As we move forward, it is crucial for educators, policymakers, and parents to engage in a forward-looking and robust dialogue about the role of technology in education. By doing so, we can ensure that technology serves as a bridge rather than a barrier to human connection and learning.

In sum, the future of education in a technology-saturated world is not just on the horizon; it is already here. The challenge lies in how we choose to navigate this new landscape, making informed decisions that prioritize the well-being and educational success of our students. By fostering an environment where technology enhances rather than detracts from the learning experience, we can prepare our students for a future where they are not just competent users of technology but also critical thinkers and lifelong learners.
