Graphene is a single layer of graphite, which is a pure crystalline form of carbon. It was first isolated in 2004 by researchers at the University of Manchester. Graphene has exceptional properties such as being the thinnest, strongest, most conductive and flexible material known. It is light, transparent and an excellent conductor of heat and electricity. These properties give graphene potential applications in areas like batteries, touchscreens, composites and biotechnology. Further research aims to utilize graphene's tunable bandgap for applications like transistors and integrated circuits.

If the 20th century was the age of plastics, the 21st
century seems set to become the age of graphene
A recently discovered material made from honeycomb
sheets of carbon just one atom thick. Science journals have been
running out of superlatives for this wondrous stuff: it is just about the
lightest, the strongest, the thinnest, the best heat and the electricity
conducting material ever discovered. Moreover, if we are to believe
the hype, it promises to revolutionize everything from computing to
car tires and solar cells to smoke detectors.
What! Is this strange and remarkable new stuff? Let us take a closer look!
History and development of permanent magnetsIjrdt Journal
Â
The history of development of permanent magnets has been reviewed. The magnet began with the mineral magnetite (Fe3O4) or lodestone, was the first hard magnet known to man with Energy Product of about 1kJ/m3. The steps of development have been classified due to the type of materials used in the manufacturing of permanent magnets. The first type of steel magnets are those which were developed to reach (BH)max of about 8kJ/m3. A big jump in the energy product and coercivity occurred after the discovery of Rare Earth magnets. A (BH)max of around 474 kJ/m3 has been achieved. A theoretical value of (BH)max of about 512kJ/m3 for Nd2Fe14B hard Phase has been reported. A 93% of this theoretical value has been achieved so far. In addition, an idea about large scale applications of Nd-Fe-B magnets has been mentioned in this work. Furthermore, some recent developments in the field of permanent magnets have been summarized in this article

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Â
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Â
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as âpredictable inferenceâ.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Â
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But thereâs more:
In a second workflow supporting the same use case, youâll see:
Your campaign sent to target colleagues for approval
If the âApproveâ button is clicked, a Jira/Zendesk ticket is created for the marketing design team
Butâif the âRejectâ button is pushed, colleagues will be alerted via Slack message

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work.

Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.
Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
Â
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.
