Qn.1

• During the first half 20th century, the temperature above which typical high grade steel changed to ductile, tearing failure mode from the brittle mode was 50 degrees Fahrenheit. Not until 1963, over 50 years after the X Incident, was the first authoritative documentation published by two researchers from the U. S. Naval Research Laboratory providing a comprehensive, quantitative analysis describing the phenomenon of ductile to brittle crack propagation in steel.

Ans

• Sinking of the Titanic

Qn.2

• Bette Nessmith Graham worked as a typist in a bank during the 1950’s .

• She was subject to making a number of typing errors , which she had to correct by over typing which dint look good .

• Starting on a basis of tempera paint she mixed with a common kitchen blender, she came up with an invention .

• What did she invent

Ans

• Correction Fluid /Liquid paper

Qn.3

• Put Fundae !

Ans

• This is the first attempt at moving atoms by man using an STM

• Donald Eigler , a researcher with IBM , was studying the effects of Xenon on metal structures , using an STM , he recorded the proceedings of his experiment

• Whilst fast forwarding the recording , he had noticed that some of the atoms had shifted place , because of the tunneling current of the STM

• To confirm that this wasn’t a co incidence , the next day he inscribed IBM using 35 xenon atoms , and hence MAN WALKED ON THE ATOM

Qn.4

• X’s were historically made of sheep gut or intestine , but their effectiveness was limited due to permeability.

• Modern X’s are made of polyurethane , polyisoprene , AT-resin , all of which have very good bio compliance , and reduced permeability

• ISO and European standards state that finished XsShould have Tensile strengths upwards of 30MPa , and should be able to expand upto 800% before tearing or failure occurs

• What am I talking about ?

Ans

• Condoms

• Sry no images

Qn.5 MEMS- Where would you find these nano assembled structures ?

Ans

• The Apple I-Phone

Video

Qn.6 High temperature reusable surface insulation – Reason for which Disaster ?

Ans

• Space shuttle Columbia Disaster

Qn.7• Colonel John Pemberton was wounded

in the American Civil War, became addicted to morphine, and began a quest to find a substitute for the dangerous opiate .

• The prototype X recipe was formulated at Pemberton's Eagle Drug and Chemical House, a drugstore in Columbus, Georgia, originally as a coca wine in 1885

• It was initially sold as a medicine Pemberton claimed X cured many diseases, including morphine addiction, dyspepsia, neurasthenia, headache, and impotence .

• X please!

Ans : Coca-Cola

Qn.8 video

• Transformium is an inspired form of X .

• X effect was first noted in 1937 and later popularised by the invention of Nitinol by the US Naval Ordnance laboratories .

• X materials are currently used in the aerospace industry , for making shape changing wings and chevrons , bio applications include temperature induced stents .

• What phenomenon am I talking about ?

Ans: shape memory alloys

Qn.9

• X element was extremely costly in the 1800s , so much so that it costed more than GOLD and Silver , the French emperor had utensils made of X specially for royalty .

• The Washington monument was supposed to have an obelisk made up of X , but considering High costs , the idea was dropped .

• In 1885 Charles Martin Hall & Paul Heroult deviced a method to easily extract X , by dissolved electrolysis.

• Hall further setup the “X Company of America” , which is called as Y Nowadays, and is the largest producer of X.

• X & Y please .

Ans

• X –

• Y -

Qn.10

• Mission / what is it made up of ?

Qn.10

• On Earth, plants remove carbon dioxide through the process of photosynthesis.

• However, in a spacecraft, carbon dioxide must be removed from the cabin air through chemical processes. with canisters that contain powdered lithium hydroxide. When air containing carbon dioxide (CO2) gets passed through the canister, it combines with the lithium hydroxide (LiOH) to form lithium carbonate (Li2CO3) and water (H2O).

• CO2 (g) + 2LiOH (s) -> Li2CO3 (s) + 3 H2O (l)

Ans

Qn.11

• Armalcolite is a titanium-rich mineral with the chemical formula (Mg,Fe2+)Ti2O5. It was first found at Tranquility Base on July 20TH

1969 .

• armalcolite is named after the three people associated with the discovery of the mineral

• WHERE Was this mineral found , and who were the three people ?

Ans

• Moon

• Neil Armstrong , Buzz Aldrin , Jim Collins

Qn.12 HABAKUK

• Project Habakkuk was a plan by the british during 2ND

World war to construct Aircraft carriers using PYKRETE .

• PYKRETE was planned to be used as an alternative to steel which was in short availability those days .

• PYKRETE had the ability to bear almost the same stresses and loads, at a cheaper cost .

• Pykrete could be machined like wood and cast into shapes like metal, and when immersed in water formed an insulating shell of wet wood pulp on its surface that protected its interior from further melting

• What was pykrete made up of ?

Qn.12

Ans : Pykrete

• Wood + ICE

Qn.14

Qn.15

• Connect !

Ans:

• ERIC Drexler’s Utility fog

• Richard feynman’s self replicating robots that will help materialise anything into the air

Qn.16 Fundae?

Ans :

• Nano particle used in Stain Glass objects

T1

• X catalyst, named after Karl and Giulio , is a catalyst used in the synthesis of polymers of 1-alkenes (α-olefins). Two broad classes of X catalysts are employed, distinguished by their solubility .

• They are Titanium / Vanadium Based catalysts that speed up the polymerisation reaction and eliminate the requirement of high pressures

• Nearly all the polyethylene products apply this method of synthesis

T2 what was first generated in 1985 and named based on these two images

T3

• A X is an instrument for imaging surfaces at the atomic level.

• The STM is based on the concept of quantum tunneling. When a conducting tip is brought very near to the surface to be examined, a bias (voltage difference) applied between the two can allow electrons to tunnel through the vacuum between them. The resulting current is a function of tip position, applied voltage, and the local density of states (LDOS) of the sample

• What Instrument is this ?

T4 What was discovered as a result of these ?
