Green Chemistry is the utilization of a set of principles that reduces or eliminates the use or generation of hazardous substances in the design, manufacture and application of chemical products *.
A reaction is considered green if there is maximum incorporation of starting materials and reagents in the final product
Most organic compounds used as feedstock are derived from petroleum, a nonrenewable resource (depleting)
A green approach is to replace these petrochemicals with chemicals derived from biological sources
The refining of organic compounds from these plant-derived materials, sometimes called biomass, is less polluting than the refining process for petrochemicals.
Many pharmaceuticals, plastics, agricultural chemicals can now be produced from chemicals derived from biomass

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).

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.

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.
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.
"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

2. Green chemistry, also called sustainable
chemistry, is a philosophy of chemical research
and engineering that encourages the design of
products and processes that minimize the use
and generation of hazardous substances*.
The utilization of a set of principles that reduces
or eliminates the use or generation of hazardous
substances in the design, manufacture and
application of chemical products**.
*As defined by United States Environmental Protection Agency

Pharmaceuticals and chemical industries though have a lesser waste
production compared to other industries like oil refining, have an opportunity
of reducing the waste further since the amount of waste per kg of product is
relatively higher
6. 2. Atom Economy
Synthetic methods should be designed to
maximise the incorporation of all materials
used in the process into the final product.
7. Atom economy (atom efficiency) describes
the conversion efficiency of a chemical process in
terms of all atoms involved (desired products
produced).
In an ideal chemical process, the amount of
starting materials or reactants equals the amount
of all products generated and no atom is wasted.
% atom economy= (MW of desired product/MW of all reactants)
*100
8. 3. Less Hazardous Chemical
Synthesis
Whenever practicable, synthetic methodologies
should be designed to use and generate
substances that possess little or no toxicity to
human health and the environment.

11. 4. Designing Safer Chemicals
Chemical products should be designed to preserve
efficacy of the function while reducing toxicity.
12. Tributyltin oxide is usually used mixed with
paints as an antifoulants for ships. This
chemical is usually toxic to marine organisms
and also bio-accumulate.
Sea-Nine®
211,
4,5-dichloro-2-n-octyl-4isothiazolin-3-one (DCOI), is now used which is
relatively less toxic.
http://academic.scranton.edu/faculty/CANNM1/environmentalmodule.html
13. 5. Safer Solvents and Auxiliaries
The use of auxiliary substances (solvents, separation
agents, etc.) should be made unnecessary
whenever possible and, when used, innocuous.

16. Ionic solvents:
Room temperature ionic liquids(RTILs) can be
used as substitutes for aromatic solvents in
chemical reactions and separation processes.
RTILs are organic salts with melting points
below 1000 C, often below room temperature,
have no vapour pressure and composed of
entirely cations and anions.
Exhibit good solvent properties and often
facilitate chemical reactions without being
transformed in the process.
Have negligible vapour pressure and miniscule
flammability.
17. Exhibit high thermal stability and wide working
temperatures.
Owing to multitude of possible combinations of
cation and anion, they are susceptible to
numerous permutations that allow various
physical and chemical properties to be adjusted
at will.
Eg: 1-butyl-3methylimidazoliumhexafluorophosphate, and
some imidazolium tetrafluoroborates
Philip E.Rakita, Ozark Fluorine Specialities
18. 6. Design for Energy Efficiency
Energy requirements should be recognized for their
environmental and economic impacts and should be
minimized. Synthetic methods should be conducted at
ambient temperature and pressure.
19. Use of alternate, recyclable and more efficient
energy resources.
Use of light energy as a source for
photochemical reactions.
Use of microwave chemistry for more efficient
energy utilization
20. 7. Use of Renewable Feedstocks
A raw material or feedstock should be
renewable rather than depleting
whenever technically and economically
practical.
21. Fermentation of glucose in the presence of
bacteria and propanoic acid gives Polyhydroxy
alkanoates (PHAs).
The PHAs are similar to polypropene and
polyethene but however are biodegradable.

PLA (polylactic acid) is another plastic that is
being made from renewable feedstocks such as
corn and potato waste.
22. 8. Reduce Derivatives
Unnecessary derivatization (blocking group,
protection/deprotection, temporary
modification of physical/chemical processes)
should be avoided whenever possible.
23. An increase in the number of synthetic steps
would eventually reduce the overall yield and
atom economy.
Protecting groups are generally used because
there is no direct way to solve the problem
without them.
Attempts to reduce the number of steps and
derivatization is considered important.
25. A green catalyst has advantages such as:
Readily separated
Readily regenerated & recycled
Long service life
Very high rates of reaction
Robust to poisons
High selectivity
Works under milder conditions
26. Certain chemicals are used as green catalysts
which reduce the incidence of toxic chemicals
formed in a reaction by converting them to less
toxic or harmless substances.
Oxidation catalysts, called Fe-TAML® (tetraamido macrocyclic ligand) activators, are made
from elements found in nature and work with
hydrogen peroxide to convert harmful
pollutants into less toxic or harmless
substances*.
*Terrence J. Collins;Teresa Heinz Professor of Green Chemistry
27. Enzymes or whole-cell microorganisms are
used.
Benefits include:
Fast reactions due to correct orientations
Orientation of site gives high stereospecificity
Substrate specificity
Water soluble
Naturally occurring
Moderate conditions
Possibility for tandem reactions
28. Phase Transfer Catalyst:
A phase transfer catalyst is a catalyst which facilitates
the migration of a reactant in a heterogeneous system
from one phase into another phase where reaction
can take place.
Ionic reactants are often soluble in an aqueous phase
but are insoluble in an organic phase unless the phase
transfer catalyst is present.
Advantages of PTC
Elimination of organic solvents
High yields and purity of products
Simplicity of the procedure
Highly scalable
Low energy cosumption and low investment cost
Minimization of industrial waste
29. Quarternary ammonium or phosphonium salts
are most widely used PTCs.
Eg: methyltrioctyl ammoniumchloride (Aliquat 336 or
Adogen 464),
Tetra-n-butylammonium bromide (TBAB)
Triethylbenzylammonium chloride (TEBA)
Cetyltrimethylammonium bromide (cetrimide)
benzyltrioctyl ammoniumchloride,
polyethylene glycoether,
crown ethers
31. Applications of PTCs:
In nucleophilic substitution reactions
Synthesis of fine chemicals
In perfumery and fragrance industry
Is synthesis of drugs like dicyclonine,
phenoperidine, oxaladine, ritaline etc.
Provides liberty of use of cheaper and easily
available raw materials like potassium
carbonate and aqueous sodium hydroxide
thereby obviating the need of severe
anhydrous conditions, expensive solvents and
dangerous bases such as metal hydrides and
organometallic reagents.
32. Williamsons ether synthesis by PTC:
High-yield etherification
No need for excess pre-formed alkoxide
Usually short cycle time and easy workup
Non-dry mild reaction conditions
33. Wittig reaction by PTC
Aliquat 336 (N-Methyl-N,N-dioctyloctan-1ammonium chloride) is used as PTC.
34. 10. Design for Degradation
Chemical products should be designed so that at the
end of their function they do not persist in the
environment and instead break down into
innocuous degradation products.
35. Plastics, long chain hydrocarbons, CFCs have
longer persistence.
Chemicals such as DDT bioaccumulate.
Drugs such as antibiotics build up in water
streams.
Design of degradable chemicals is the need of
the hour.
Polylactic acid:
Manufactured from renewable resources such as corn or
wheat;
Uses 20-50% fewer fossil fuels than conventional plastics
PLA products can be recycled or composted
36. 11. Real-time Analysis for
Pollution Prevention
Analytical methodologies need to be further
developed to allow for real-time in-process
monitoring and control prior to the formation
of hazardous substances.
37. In the process of a chemical reaction, analysing
when a reaction is exactly complete can save a
lot of energy, waste and time.
Overdoing a reaction may result in energy
wastage and under-doing the same may result in
material wastage.
An advanced and sophisticated analytical tool
helps reduce this pollution
38. 12. Inherently Safer Chemistry for
Accident Prevention
Substance and the form of a substance used in
a chemical process should be chosen so as to
minimize the potential for chemical accidents,
including releases, explosions, and fires.
39. Use of potential toxic, hazardous and highly
inflammable chemicals may result in accidents
which eventually lead to pollution and danger to
plant and animal life.
U.S. Public Interest Research Group Reports
(April 2004) find that chemical industry has had
more than 25,000 chemical accidents since 1990
More than 1,800 accidents a year or 5 a day.
In Bhopal gas tragedy, release of 40 tons of
Methyl isocyanate (MIC) took the lives of 15000
people leaving hundreds of thousands seriously
affected.
