UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.
Micro RNA genes and their likely influence in rice (Oryza sativa L.) dynamic ...Open Access Research Paper
Micro RNAs (miRNAs) are small non-coding RNAs molecules having approximately 18-25 nucleotides, they are present in both plants and animals genomes. MiRNAs have diverse spatial expression patterns and regulate various developmental metabolisms, stress responses and other physiological processes. The dynamic gene expression playing major roles in phenotypic differences in organisms are believed to be controlled by miRNAs. Mutations in regions of regulatory factors, such as miRNA genes or transcription factors (TF) necessitated by dynamic environmental factors or pathogen infections, have tremendous effects on structure and expression of genes. The resultant novel gene products presents potential explanations for constant evolving desirable traits that have long been bred using conventional means, biotechnology or genetic engineering. Rice grain quality, yield, disease tolerance, climate-resilience and palatability properties are not exceptional to miRN Asmutations effects. There are new insights courtesy of high-throughput sequencing and improved proteomic techniques that organisms’ complexity and adaptations are highly contributed by miRNAs containing regulatory networks. This article aims to expound on how rice miRNAs could be driving evolution of traits and highlight the latest miRNA research progress. Moreover, the review accentuates miRNAs grey areas to be addressed and gives recommendations for further studies.

"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

The objective of this work is to contribute to valorization de Nephelium lappaceum by the characterization of kinetics of drying of seeds of Nephelium lappaceum. The seeds were dehydrated until a constant mass respectively in a drying oven and a microwawe oven. The temperatures and the powers of drying are respectively: 50, 60 and 70°C and 140, 280 and 420 W. The results show that the curves of drying of seeds of Nephelium lappaceum do not present a phase of constant kinetics. The coefficients of diffusion vary between 2.09.10-8 to 2.98. 10-8m-2/s in the interval of 50°C at 70°C and between 4.83×10-07 at 9.04×10-07 m-8/s for the powers going of 140 W with 420 W the relation between Arrhenius and a value of energy of activation of 16.49 kJ. mol-1 expressed the effect of the temperature on effective diffusivity.

The topic is very vast but I have tried to cover it in one
lecture and I will give the links for more details of
each sub-topic 2009

3. Performance Objectives:
To understand the importance of Green chemistry for
sustainability
To design and interpret greener route to the traditional
chemical reactions
To learn how to teach green chemistry as a lab course

4. Sustainability
• Meeting the needs of the present generation without
compromising the needs of future generations
• Green chemistry: technologies of the invention, design
and application of chemical products and processes to
reduce or to eliminate the use and generation of
hazardous substances ,and where possible utilize
renewable raw materials
Primary pollution prevention not remediation
Use of chemistry for improved environmental performance
Is the goal

8. Principles of Green Chemistry
Prevent waste.
Design safer chemicals and products.
Design less hazardous chemical syntheses.
Use renewable feed stocks.
Use catalysts, not stoichiometric reagents: Catalysts are used in small amounts and
can carry out a single reaction many times. They are preferable to stoichiometric
reagents, which are used in excess and work only once.
Avoid chemical derivatives: Avoid using blocking or protecting groups or any
temporary modifications if possible. generate waste.
Maximize atom economy.
Use safer solvents and reaction conditions
Increase energy efficiency.
Design chemicals and products to degrade after use.
Analyze in real time to prevent pollution.
Minimize the potential for accidents.

• If the chemical reaction of the type
• A + B P + W
• Find alternate A or B to avoid W
• Example 1:
• Disinfection of water by chlorination. Chlorine
oxidizes the pathogens there by killing them,
but at the same time forms harmful chlorinated
compounds.
• A remedy is to use another oxidant, such as

zenab_77@mans.edu.eg
11. Example 2 of green chemistry
• Production of allyl alcohol CH2=CHCH2OH
• Traditional route: Alkaline hydrolysis of allyl chloride, which
generates the product and hydrochloric acid as a by-product
• Greener route, to avoid chlorine: Two-step using propylene
(CH2=CHCH3), acetic acid (CH3COOH) and oxygen (O2)
• Added benefit: The acetic acid produced in the 2nd
reaction
can be recovered and used again for the 1st
reaction, leaving
no unwanted by-product.
CH2=CHCH2Cl + H2O CH2=CHCH2OH + HCl
problem product
CH2=CHCH2OCOCH3 + H2O CH2=CHCH2OH + CH3COOH
CH2=CHCH3 + CH3COOH + 1/2 O2 CH2=CHCH2OCOCH3 + H2O

12. Example 3 of green chemistry
• Production of styrene (=benzene ring with CH=CH2 tail)
• Traditional route: Two-step method starting with benzene,
which is carcinogenic) and ethylene to form ethylbenzene,
followed by dehydrogenation to obtain styrene
• Greener route: To avoid benzene, start with xylene (cheapest
source of aromatics and environmentally safer than benzene).
• Another option, still under development, is to start with
toluene (benzene ring with CH3 tail).

13. Green chemistry education
Chemistry students need to be encouraged to
consider the principles of green chemistry when
designing processes and choosing reagents
Interactive Teaching Units (ITU) have been
developed specifically to introduce undergraduate
students to green chemistry
There are numerous scholarships and grants
available for researchers and young scholars who
are furthering the goals of green chemistry

14. conclusion
Green Chemistry:Green Chemistry:
Preventing Pollution
Sustaining the Earth
Green chemistry has come a long way since its birth in 1991,
growing from a small grassroots idea into a new approach to
scientifically-based environmental protection
All over the world, governments and industries are working
with “green” chemists to transform the economy into a
sustainable enterprise
Who knows? Green chemistry may be the next social
