IFPRI Policy Seminar "From Concepts to Realities Promising nanotech applications for agriculture, food and water safety in developing countries" by Guillaume Gruere on 14 November 2011
For many decades, nanotechnology has been developed with cooperation from researchers in several fields of studies including physics, chemistry, biology, material science, engineering, and computer science. Nanotechnology is engineering at the molecular (groups of atoms) level. It is the collective term for a range of technologies, techniques and processes that involve the manipulation of matter at the smallest scale (from 1 to 100 nm2).The nanotechnology provides better future for human life in various fields. In future nanotechnology provides economy, ecofriendly and efficient technology which removes all difficult predicaments which is faced by us in today life scenario. Nanotechnology is the technology of preference to make things small, light and cheap, nanotechnology based manufacturing is a method conceived for processing and rearranging of atoms to fabricate custom products.
The nanotechnology applications have three different categories nanosystems, nanomaterials and nanoelectronics. The impact of the nanotechnology occurred on computing and data storage, materials and manufacturing, health and medicine, energy and environment, transportation, national security and space exploration. There are many applications of nanotechnology which are exciting in our life such as nanopowder, nanotubes, membrane filter, quantum computers etc.
But there are several problems which are occurred with the exploration of the nanotechnology such as the wastes released while making the materials for nanotechnology are released into the atmosphere and can even penetrate human and animal cells and effect their performance, agricultural countries will lose their income as nanotechnology will take over, if any damage is done at the molecular level then it is not possible to revert it.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
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.

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).

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.

3. NANOTECHNOLOGY
Nanotechnology is the engineering of functional systems at the molecular scale.
The comparative size of a nanometer to a meter is the same as that of a marble to
the size of the earth. A nanometer is one billionth of a meter, roughly the width of
three or four atoms. The average human hair is about 25,000 nanometers wide.
Two main approaches are used in nanotechnology. In the "bottom-up" approach, materials and devices are
built from molecular components which assemble themselves chemically by principles of molecular
recognition. These seek to arrange smaller components into more complex assemblies.
In the "top-down" approach, nano-objects are constructed from larger entities without atomic-level control.
These seek to create smaller devices by using larger ones to direct their assembly.
3
5. Branches of nanotechnology
Green nanotech – use of
nanotechnology to enhance the
environmental-sustainability of
processes currently producing
negative externalities. It also
refers to the use of the products
of nanotechnology to enhance
sustainability.
Nanoengineering– practice of
engineering on the nanoscale.
Wet nanotechnology– involves
working up to large masses from small
ones.
Nanobiotech – intersection of
nanotechnology and biology.
5
6. Two forms of
nanomedicine that
have already been
tested in mice and are
awaiting human trials
are using gold
nanoshells to help
diagnose and
treat cancer and
using
liposomes as vaccine
adjuvants and as
vehicles for drug
transport
6
7. Nanotechnology in cancer
treatment
Nanomedical approaches to drug
delivery center on
developing nanoscale particles or
molecules to improve
drug bioavailability.
Bioavailability refers to the
presence of drug molecules where
they are needed in the body and
where they will do the most good.
Drug delivery focuses on
maximizing bioavailability both at
specific places in the body and
over a period of time.
7
8. DRUG DELIVERY
The basic point to use drug
delivery is based upon three
facts:
a) efficient encapsulation of the
drugs,
b) successful delivery of said
drugs to the targeted region of
the body, and
c) successful release of that drug
there.
8
9. Researchers at Rice
University under Prof. Jennifer
West, have demonstrated the
use of 120 nm
diameter nanoshells coated
with gold to kill cancer tumors
in mice. The nanoshells can be
targeted to bond to cancerous
cells by
conjugating antibodies or pepti
des to the nanoshell surface.
By irradiating the area of the
tumor with an infrared laser,
which passes through flesh
without heating it, the gold is
heated sufficiently to cause
death to the cancer cells.
9
10. GOLD NANO
PARTICLES
Nanoparticles of cadmium
selenide (quantum dots)
glow when exposed to
ultraviolet light. When
injected, they seep
into cancer tumors. The
surgeon can see the
glowing tumor, and use it
as a guide for more
accurate tumor removal.
10
11. NANOROBOTS
Nanomedicine would make use of
these nanorobots , introduced into
the body, to repair or detect
damages and
infections. Carbon could be the
primary element used to build these
nanorobots due to the inherent
strength and other characteristics of
some forms of carbon
(diamond/fullerene composites), and
nanorobots would be fabricated in
desktop nanofactories specialized for
this purpose.
11
12. With the population mounting in Asia and African regions, the global
population is expected to touch 7.5 billion by 2020 and 9 billion by 2050.
Needless to say, there is an increased need to use scientific technology
to boost agricultural production.
Nanotechnology has the potential to revolutionize the agricultural and
food industry with new tools for the molecular treatment of diseases, rapid
disease detection, enhancing the ability of plants to absorb nutrients etc.
Smart sensors and smart delivery systems will help the agricultural
industry combat viruses and other crop pathogens. In the near future
nanostructured catalysts will be available which will increase the
efficiency of pesticides and herbicides, allowing lower doses to be used
Are We Using Nano-
Biotechnology to Increase
Crop Yield?
12
13. The union of biotechnology and
nanotechnology in sensors will create
equipment of increased
sensitivity, allowing an earlier response to
environmental changes. For example:
• Nanosensors utilising carbon
nanotubes12 or nano-cantilevers13 are
small enough to trap and measure
individual proteins or even small
molecules.It seems that the
long, skinny, strawlike structures promote
water uptake, because seeds exposed to
carbon nanotubes contained more
moisture.
• Nanoparticles or nanosurfaces can be
engineered to trigger an electrical or
chemical signal in the presence of a
contaminant such as bacteria.
13
14. Some nanoparticle products may have unintended consequences.
Researchers have discovered that bacteriostatic silver nanoparticles used in
socks to reduce foot odour are being released in the wash. These particles
are then flushed into the waste water stream and may destroy bacteria which
are critical components of natural ecosystems, farms, and waste treatment
processes.
Researchers have found that when rats breathed in nanoparticles, the
particles settled in the brain and lungs, which led to significant increases in
biomarkers for inflammation and stress response and that nanoparticles
induce skin aging through oxidative stress in hairless mice.
carbon nanotubes – a poster child for the “nanotechnology revolution” –
could be as harmful as asbestos if inhaled in sufficient quantities.
14
15. Is nanotechnology bad or good?
Nanotechnology offers great potential for
benefit to humankind, and also brings
severe dangers. While it is appropriate to
examine carefully the risks and possible
toxicity of nanoparticles and other products
of nanoscale technology, the greatest
hazards are posed by malicious or unwise
use of molecular manufacturing.
15
