Nanotechnology involves manipulating matter at the nanoscale (1 billionth of a meter) to create new materials and devices. There are two main approaches to synthesizing nano-phase materials: top-down, which breaks down bulk materials into nano sizes, and bottom-up, which builds materials atom by atom. Electrospinning is a commonly used bottom-up technique to produce nanofibers less than 500 nm in diameter for applications such as filters, protective fabrics, and tissue scaffolds. Nanotechnology has applications in fields like electronics, energy, materials, medicine, and textiles. It promises to revolutionize industries and improve lives through targeted drug delivery, artificial organs, stronger/lighter materials, pollution cleanup, and more.

Nanotechnology and potential in Cancer therapy and treatmentladen12
this presentation focuses on new nanotechnology and it possible use in detection and therapy with cancer. it was prepared by final year biochemistry student at NCU.
This is a complete basic and short guide about Nanotechnology i.e. what it means, what it will do, its applications, its uses, its future, disadvantages and almost everything. I make it little bit eye catchy and funnier by adding relative graphics and pictures so you can never get bored. At the end you found it 1000 times more interesting and funnier. Enjoy my work world.
Nanotechnology is defined as the study and use of structures between 1 nanometer and 100 nanometers in size. To give you an idea of how small that is, it would take eight hundred 100 nanometer particles side by side to match the width of a human hair
In their ongoing quest to improve existing products by creating smaller components and better performance materials, all
at a lower cost, the number of companies that will manufacture"Nano products" (by this definition) will grow very fast and Soon make up the majority of all companies across many industries. Evolutionary nanotechnology should therefore be
viewed as a process that gradually will affect most companies and Industries.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
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
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 “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
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).

ConclusionConclusion
by definiton as you can see ”it’s the art of manipulating matter at the nanoscale level”
1. Its a bit difficult to realize how small the nano-scale is. To make things easier to get, we can say that one nanometre (nm) is one billionth of a metre.
2. Lets see some examples to make it clear
In the picture on the right, we can see a man staring at his picked hair trying to figuring out the diameter of it, he will essentially come to the conclusion that a human hair is 100,000nm thick, while a DNA molecule is only 2 nms wide.
Now this is a bit informative 3d chart, providing the size comparisons between different objects raised to the power of 10 meters. Here you can see, a 6 foot man is 1.62 meters or roughly around 2 billion nms tall. While on the other hand, a sample of a DNA molecule, as we have already seen in the previous slide, is approx. 2 nms long.
Nano tech is the design characterization production and application structures, devices and system by controlling shape & size at the nano scale.
This technology that can work at the Molecular level, atom by atom to create large structures with improved molecular organization.
