Spoorthi Kulkarni completed a chemistry project on dyeing fabrics with malachite green. The project involved dyeing wool and cotton cloth directly with the dye as well as using mordants like sodium carbonate, tannic acid, and tartaric acid for indirect cotton dyeing. Direct dyeing of wool produced a fast color while direct cotton dyeing resulted in a color that was not fast to washing and had low intensity. Indirect cotton dyeing using mordants produced a fast, high intensity color. The conclusion was that indirect dyeing is needed for cotton to produce a durable color from malachite green dye.
1. Mitesh Kumar, a 12th grade student, completed an investigatory project on dyeing cotton clothes with malachite green under the guidance of his teacher Mr. Deepak Pandya.
2. The project involved dyeing cotton cloth both with and without the use of mordants like sodium carbonate, tannic acid, and tartar emetic.
3. Observations showed that cotton dyed without mordants had dull and non-fast colors while cotton dyed with mordants had vibrant and wash-fast colors.

Reversible electrodes with respect to hydrogen ionmishukbiswas
This document discusses different types of electrodes that are reversible with respect to hydrogen ions (H+ ions). It specifically describes the reversible hydrogen electrode (RHE), standard hydrogen electrode, glass electrode, and quinhydrone electrode. The RHE acts as both an anode and cathode and follows the Nernst equation. It involves the reversible reaction of H+ ions and electrons producing hydrogen gas. The standard hydrogen electrode provides the standard potential of 0 volts under specific temperature and pressure conditions. Glass electrodes are commonly used to measure pH based on the Nernst equation. Quinhydrone electrodes also follow the Nernst equation and can act as either an anode or cathode under acidic conditions.

Decolonizing Universal Design for LearningFrederic Fovet
UDL has gained in popularity over the last decade both in the K-12 and the post-secondary sectors. The usefulness of UDL to create inclusive learning experiences for the full array of diverse learners has been well documented in the literature, and there is now increasing scholarship examining the process of integrating UDL strategically across organisations. One concern, however, remains under-reported and under-researched. Much of the scholarship on UDL ironically remains while and Eurocentric. Even if UDL, as a discourse, considers the decolonization of the curriculum, it is abundantly clear that the research and advocacy related to UDL originates almost exclusively from the Global North and from a Euro-Caucasian authorship. It is argued that it is high time for the way UDL has been monopolized by Global North scholars and practitioners to be challenged. Voices discussing and framing UDL, from the Global South and Indigenous communities, must be amplified and showcased in order to rectify this glaring imbalance and contradiction.
This session represents an opportunity for the author to reflect on a volume he has just finished editing entitled Decolonizing UDL and to highlight and share insights into the key innovations, promising practices, and calls for change, originating from the Global South and Indigenous Communities, that have woven the canvas of this book. The session seeks to create a space for critical dialogue, for the challenging of existing power dynamics within the UDL scholarship, and for the emergence of transformative voices from underrepresented communities. The workshop will use the UDL principles scrupulously to engage participants in diverse ways (challenging single story approaches to the narrative that surrounds UDL implementation) , as well as offer multiple means of action and expression for them to gain ownership over the key themes and concerns of the session (by encouraging a broad range of interventions, contributions, and stances).

3. ACKNOWLEDGMENT
I WOULD TO LIKE TO EXPRESS MY
SPECIAL THANKS OF GRATITUDE TO
MY TEACHER (A.K. SINDHU) AS WELL
AS OUR PRINCIPAL (G.V. SRINIVASA
RAO) WHO GAVE ME THE GOLDEN
OPPORTUNITY TO DO THIS WONDERFUL
PROJECT ON THE TOPIC (TO PREPARE
ARTIFICIAL SILK FROM COTTON
WOOL) , WHICH ALSO HELP ME IN
DOING A LOT OF RESEARCH AND I
CAME TO KNOW ABOUT SO MANY
NEW THINGS. I AM REALLY THANKFUL
TO THEM.
SECONDLY, I WOULD ALSO LIKE TO
THANK MY PARENTS AND FRIENDS
WHO HELPED ME A LOT IN FINALIZING
THIS PROJECT WITHIN THE LIMITED
TIME FRAME.

6. INTRODUCTION
CELLULOSE IS A NATURE'S OWN GIANT
MOLECULE. IT IS THE FIBROUS MATERIAL
THAT EVERY PLANT FROM SEA WEED TO
THE SEQUOIA MAKES BY BAKING
GLUCOSE MOLECULES IN LONG CHAINS.
THE CHAIINS ARE BOUND TOGETHER IN
THE FIBERS THAT GIVE PLANTS THEIR
SHAPE AND STRENGTH. WOOD HAS NOW
BECOME THE MAIN SOURCE OF
CELLULOSE. SINCE IT CONTAINS ONLY
40% TO 50% CELLULOSE. THE
SUBSTANCE MUST BE EXTRACTED
BY'PULPING' THE LOGS ARE FLAKED AND
THEN SIMMERED IN CHEMICALS THAT
DISSOLVED THE TARRY LIGNIN, RESINS
AND MINERALS. THE REMAINING PULP
ABOUT 93% CELLULOSE IS DRIED AND
7. ROLLED INTO SHEETS-RAW MATERIAL
FOR PAPER, RAYON AND OTHER
PRODUCTS. IT CAN OBTAINED IN 2 WAYS:
1. VISCOSE PROCESS:
CELLULOSE IS SOAKED IN 30% CASTIC
SODA SOLUTION FOR ABOUT 3
HOURS. THE ALKALI SOLUTION IS
REMOVED AND THE PRODUCT IS
TREATED WITH CS2 . THIS GIVES
CELLULOSE XANTHATE, WHICH IS
DISSOLVED IN NAOH SOLUTION TO
GIVE VISCOUS SOLUTION. THIS IS
FILTERED AND FORCED THROUGH THE
SPINNERET INTO DILUTE
H2SO4 SOLUTIONS, BOTH OF WHICH
HARDEN THE GUM LIKE THREAD INTO
RAYON FIBERS. THE PROCESS OF
MAKING VISCOSE WAS DISCOVERED
BY C. F. CROSS AND E. J. BEVAN
IN1891.
8. 2. ARITIFICIAL SILK (CUPRO) :
ARTIFICIAL SILK IS OBTAINED BY
DISSOLVING COTTON WOOL BALLS IN
A DEEP BLUE COPPER AMMINE
COMPLEX. THE LATTER IS OBTAINED
BY DISSOLVING AMMONIA SOLUTION
INTO COPPER (II) CARBONATE
HYDROXIDE. TO IT SULPHURIC ACID
(H2SO4) IS ADDED AND CUPRO, AN
ARTIFICIAL SILK IS OBTAINED.
REACTIONS:
CU(OH)2 CO3 + 8NH3.H2O ----
(GREEN)
[CU(NH3)4]CO3 + [CU(NH3)4](OH)2 + 8 H2O
9. (DEEP BLUE COLOUR)
MATERIALS REQUIRED :
COPPER (II) CARBONATE HYDROXIDE,
AMMONIA SOLUTION, COTTON WOOL,
GLASS BEAKER, SYRINGE, SULPHURIC
ACID.
PROCEDURE :
ADD COPPER (II) CARBONATE
HYDROXIDE INTO A BEAKER.
TO THE ABOVE BEAKER, ADD
AMMONIA SOLUTION.
A DEEP BLUE COPPER AMMINE
COMPLEX IS FORMED.
THE SOLUTION IS DECANTED INTO
ANOTHER GLASS BEAKER IN ORDER
10. TO SEPARATE PRECIPITATE FROM IT.
PUT SOME COTTON WOOL BALL IN
THIS GLASS BEAKER. THE COTTON
WOOL CONSISTS OF CELLULOSE.
CELLULOSE FORMS A COMPLEX WITH
THE COPPER IONS AND DISSOLVES
BECAUSE OF THIS.
SUCK THE WOOL WITH THE HELP OF
SYRINGE.
THE COMPLEX IS ADDED TO A
SOLUTION OF SULPHERIC ACID WITH
THE HELP OF SYRINGE. IN AN ACIDIC
MEDIUM, THE CELLULOSE
REGENERATES IN THE FORM OF LONG
FIBRES.
THE COPPER – CELLULOSE COMPLEX
IN THE FIBRES MAKES THEM BLUE.
WHEN IN AN ACIDIC MEDIUM, THE
COMPLEX GRADUALLY BREAKS UP
AND THE FIBRES BECOME
11. COLOURLESS.
NOW, TAKE OUT THE ARTIFICIAL SILK
CAREFULLY OUT OF THE BEAKER AND
PLACE IT ON A WATCH GLASS.
AT THE SAME TIME, COPPER IONS
COLOUR THE SOLUTION BLUE.
CUPRO, AN ARTIFICIAL SILK ALSO
KNOWN AS 'RAYON' IS MADE OF
FIBRES THAT ARE PRODUCED THIS
WAY.
13. PRECAUTIONS :
● DO NOT TOUCH ANY CHEMICAL
WITH HAND AS SOME OF THEM MAY
BE CORROSIVE.
● DO NOT USE CRAKED GLASS
APPARATUS SUCH AS BEAKERS.
● USE A THICK NEEDLE OTHERWISE
FIBRES WON'T COME OUT.
● THE APPARATUS USED FOR
PREPARING DEEP BLUE COPPER
AMMINE COMPLEX SHOULD BE
ABSOLUTELY CLEAN.
● MAKE SURE THAT THE NEEDLE
OF THE SYRINGE IS NOT CLOGGED.
● NEVER TASTE A CHEMICAL OR
PLACE A CHEMICAL ON THE PALM OF
YOUR HAND.
● DO NOT THROW SOLID WASTE
14. MATERIAL LIKE WET COTTON WOOL,
TEST TUBE PIECES ETC IN THE SINK.
CONCLUSION :
RYON HAS SILK-LIKE AESTHETIC WITH
SUPERB DRAPE AND FEEL AND RETAINS
ITS RICH BRILLIANT COLOURS. ITS
CELLULOSIC BASE CONTRIBUTES MANY
PROPERTIES SIMILIAR TO THOSE OF
COTTON OR ANY OTHER NATURAL
CELLULOSIC FIBRES. RYON IS MOISTURE
ABSORBENT, BREATHABLE,
COMFORTABLE, TO WEAR AND EASILY
DYED IN VIVID COLOURS.
RYON IS COMFORTABLE, SOFT TO THE
SKIN AND HAS MODERATE DRY
STRENGTH AND ABRASION
RESISTANCE. LIKE OTHER CELLULOSIC
FIBRES, IT IS NOT RESILIENT, WHICH
MEANS IT WILL WRINKLE. RYON
WITHSTANDS IRONING TEMPERATURE
SLIGHLY LESS THAN THAT OF COTTON.
15. IT MAY BE ATTACKED BY TERMITES, BUT
GENERALLY RESISTS INSECT DAMAGE.
ONE OF RYON'S STRENGTHS IS ITS
VERSATILITY AND ABILITY TO BLEND
EASILY WITH MANY FIBRES –
SOMETIMES TO REDUCE COST, OTHER
TIMES FOR LUSTER, SOFTNESS OR
ABSORBENCY.
BECUSE OF EXCESSIVE FLAMMABILITY
IT IS INSPIRED THE FLAMMABLE FABRICS
ACT. FFA ENACTED BY THE U.S.
DEPATMENT OF COMMERCE IN 1953 IN
RESPONSE TO PUBLIC CONCERN OVER A
NUMBER OF SERIOUS BURN ACCIDENTS
INVOLVING
BURSHED RYON HIGH PILE SWEATER
(REFERRED TO US “TORCH SWEATER”)
AND COULD EASILY CATCH FIRE.
