Science and technology studies, or science, technology and society studies (STS) is the study of how society, politics, and culture affect scientific research and technological innovation, and how these, in turn, affect society, politics and culture.
Science, Technology and Society (STS) is an interdisciplinary field that studies the conditions under which the production, distribution and utilization of scientific knowledge and technological systems occur; the consequences of these activities upon different groups of people.
Why is it that everyone is in the pursuit of the good life? One must find the truth what the good is before one can even try to locate that which is good.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

4. A metre is about the distance between the tip of your nose to the end of your hand. A nanometre is a billionth of a metre. 1 1,000,000,000 A nanometre is the unit of measurement used in the nanoscale.
5. A human hair is 40,000 – 200,000 nanometre wide. A man’s beard grows a nanometre per second. When a seagull lands on an oil tanker the ship dips down one nanometre. A nanometre is about the width of 6 bonded carbon atoms. Nanoparticles have at least one dimension within the range from 1 to 100 nanometres. Quite a few nanometres here! C 60 is a nanoparticle as its diameter is just over 1 nm
6.
7. Flea 10 -3 m or 1,000,000 nm in length Red Blood cells 10 -5 m or 6000 nm in diameter DNA 10 -8 m or 2.5nm in diameter. Nanoparticle 10 -9 m. One dimension between 1 and 100 nm. Anything Nano is defined as having one of its dimensions smaller than 100 nanometres ( nm) . Dog 10 0 m or 1,000,000,000 nm in length.
8. A water molecule which measures approximately 0.5 nm is about as big in relation to an apple as an apple is to planet Earth. It’s a long way down to the nanoscale!
9. Nanoparticles are just tiny bits of a larger material but what happens when you create such small pieces? Images of gold nanoparticles courtsey of Paul Rhatigan, Cambridge University.
13. Nanoparticles have more surface area . This makes them more reactive since chemical reactions happen on the surface. More reactive means potentially more useful.
14. In a cubic centimetre of material one in 10 million atoms are on the surface but for a cubic nanometre, 80% of atoms are on the surface and potentially ready to react! Images courtesy of Dr Colm Durkan, Cambridge University.
15. Size is the key here! At the Nanoscale a material’s properties can change dramatically. These could be their boiling points, solubility or catalytic activity. With only a reduction in size materials can exhibit new properties, properties they do not possess when they are on a larger or macro scale. The normal ‘classical’ laws of physics no longer apply!
16.
17. Even mechanical and electrical properties can be influenced by size! Graphene is brittle and non-conductive Carbon nanotubes are like graphene sheets but rolled up…however they have totally different properties. Did you know? Carbon nanotubes are much stronger than steel yet much lighter, and they can be conductive.
18. So how do scientists work on such a tiny scale?
19.
20. Mainly because microscopes have become more sophisticated. The first microscopes to be developed in around 1665 opened up a whole new world for scientists. For the first time cells and structures of nature that we are familiar with now became visible. Public opinion was fearful of this voyage into the unseen world of the microscopic. Micrographia 1665 .
21. Now we have microscopes that can see even further into this world, actually to the atoms that are the very building blocks of our living world. These more sophisticated microscopes are known collectively as Scanning Probe Microscopes or SPMs.
22. A Scanning Probe Microscope uses an extremely fine probe tip (sometimes ending in only a few atoms) and runs over the surface feeling for contours and shapes. www.tut.fi Probe tip feeling for shapes. Examples include: A tomic F orce M icroscope, S canning T unnelling M icroscope
23. A cantilever, similar to a diving board, is attached to the tip of an Atomic Force Microscope or AFM . The whole thing moves up and down as the tip moves over the atomic–scale hills and valleys of a sample’s surface. A laser reflects off the back of the cantilever. When the cantilever deflects, so does the laser beam. A detector in a computer records the movement of the laser and translates that data into an image, such as the images on the right. cantilever Laser detector computer Sample Probe tip This is a diagram of an Atomic Force Microscope , or AFM Images courtesy of T. Oppenheim, Cambridge University
24. Scanning tunnelling microscope. Images courtesy of Cambridge university, Nanoscience Centre. A scanning tunnelling microscope works by having a tiny probe which scans across a surface picking up variations in the current that runs between itself and the atoms on the surface. This probe is made of conducting material (usually Tungsten) and the very end of it is only 1 atom wide! A tungsten tip for STM imaging. These variations in current are translated into images such as the ones to the right.
25. The probe tips can also be used to move individual atoms. The image shows iron atoms which have been moved individually. Image originally created by Don Eigler, IBM corporation.
26.
27. This idea of building things from the atoms and working up is interesting for researchers. Computers and phones are getting smaller yet more powerful. This trend demands smaller and smaller components, getting down to the nanoscale. It makes sense to be able to create these nano-devices from the ‘bottom up’. Rather than the more traditional ‘top down’ approach to manufacturing. Manufacturing from the ‘bottom up’ would mean less energy and less waste. ‘ BOTTOM UP’ ‘ TOP DOWN’
28. Moving atoms individually is still not a viable technique for creating nanostructures because it’s too slow. However there is another process called ‘SELF ASSEMBLY’, often seen in nature, which scientists can exploit. Atoms, molecules or nanoparticles will arrange themselves into larger structures if they have the right properties and environments. This process plays a central role in the construction of DNA, cells, bones and viruses. These all self assemble without assistance.
29. Another way scientists can create nano-sized devices is a process called lithography . It is often used to make computer chips . It works in a very similar way to printing or if you were spray painting over a stencil. But lithography uses light or electrons instead of ink or paint. This is a finished structure created by E-beam lithography. Photolithography uses light and structures as small as around 20 nm can be made. If scientists want to make even smaller structures (around 5 nm), they use electrons instead of light, this is called E-beam lithography .

30. They are stronger yet considerably lighter than steel and flexible. They can behave like metals but also semi-conductors, they are great at transmitting heat and they are assembled from carbon atoms. With properties like this they could play a pivotal role in the development of new materials and future electronics. In this image each letter is made up of hundreds of nanotubes! Even when nanotubes are fully grown, each entity is smaller than a human blood cell. Are an exciting discovery which could revolutionise materials of the future.

31. Nature is an expert in making nanoscale structures. This is why scientists look to nature for inspiration when researching how to construct at this tiny scale.
32.
33. Biomimicry Biomimicry is the term scientists copying nature. By studying Lotus leaves and their structure scientists have designed non-wetting materials and self-cleaning windows. By studying butterfly wings and their nanostructures scientists have explained how light can interact differently with surfaces. This has helped design security holograms and hair products! Even the nano structure of a Toucan’s beak has offered insight into designing ultra-light aircraft components. Butterfly wings under the microscope
34. Geckos’ feet have nanostructures. Geckos’ feet are covered in tiny hair-like structures called setaes. These structures can get so close to a surface that weak ‘sticky’ interactions between molecules become significant. The result is strong adhesion which is entirely due to Van der Waals forces. Scientists have been inspired by this nanostructure to create internal bandages which still adhere even in a wet environment. Nature is experienced in working on the nanoscale and we can learn a lot from its success at creating natural nanotechnology. Image credit: A.Dhinojwala, University of Akron Image credit: C.

36. Nanotechnology is already in our lives. Nanoelectronics has enabled the miniaturisation of electronic gadgets in daily use. Some tennis balls stay bouncy for longer thanks to a nano-structured inner layer. Some tennis racquets are made from a carbon-based nanocomposite making them stronger and lighter than ever before. Socks that contain antibacterial nanoparticles of silver are supposed to keep your feet healthy and odour free.
37. Some textiles are made very hydrophobic using liquid repellent nanostructures which enable them to be water and stain resistant. Cosmetics and sunscreens which contain nanoparticles can promote better protection and comfort. Sun glasses which have a nano-structured coating are easier to clean, harder to scratch, anti static,anti-misting and anti-bacterial. Nanotechnology is already in our lives.
38.
39. Nanotechnology is a multi- disciplinary subject as it incorporates many different areas of science and industry:
40.
41. It is the potential of Nanotechnology that makes it so interesting. Some areas where Nanotechnology could have a dramatic impact include Medical Applications e.g. cancer therapy Information Technology e.g. faster computers Energy Solutions e.g. such as more economical fuel cells and solar cells Areas which have an impact on all our lives.
Teacher’s notes:Particles of matter can be nano-sized. They tend to measure between 1-100nm and are referred to as ‘nanoparticles’.
Teacher’s notes: If you take a cube(1 x 1 cm), then open the cube so it lies flat, the surface area becomes 6 cm squared. Take the same cube and divide into 8 little cubes and lay them flat the surface area is twice as much, 12m squared. More surface area equals more reactivity.
Teacher’s notes:Example - This is why a lump of sugar takes longer to dissolve than granulated sugar. Can do demonstration at this point of solid iron and iron powder, or two stomach anti-acid tablets, one crushed up and one whole and see which dissolves quicker.
Teacher’s notes:Images show the surface of gold and silicon. The bumps you can see are the actual atoms.
Teacher’s notes: Introduce the concepts of ‘top down’ ‘bottom up’ production.
Vic – mention top down on this slide
Teacher’s notes:Can use the treated textiles at this point to demonstrate.
