1. How was the first quasicrystal discovered? - The quasicrystal was discovered while Daniel Shechtman was experimenting on a chilled molten mixture of aluminium and manganese which revealed a 10-fold symmetry.
2. Compare crystals and quasicrystals. - the crystal, the patterns are tightly packed, they have no space in between, and look the same in whatever angle. And the quasicrystal, the atoms exhibit a regular pattern, but the pattern is not repeated.
3. What are the uses of quasicrystals? - They are used for surgical needles, razor, nonstick frying pan, and light emitting diode lights.
p. 13
1. How does a magnetic tongue work? - It uses nuclear magnetic resonance spectroscopy to assess flavours.
2. Do you think the magnetic tongue is useful? Why or why not? - Yes, because the magnetic tongue is as good as a professional food taster when it comes to assessing flavours.
3. What is NMR spectroscopy? - It is an analytic tool that allows scientists to study the physical, biological, and chemical properties of matter.
p. 19
1. What are the new features in the family of compounds made by the researchers in UJI? - It can be used with a wider range of solvents and will not cause toxic or allergic reactions to users.
2. Give some examples of gels found in your home. Describe them - Yoghurts, fruity gelatine, sweet jelly candies, styling gel and cream shampoo.
3. Do you think the new material is useful for you? Why or why not? - Yes, because it won’t harm me by not causing toxic or allergic reaction.
p. 21
1. How does Ling Zang’s mercury tester work? - It uses perylene dye and a DNA binding group for detecting mercury concentrations.
2. What are the causes of mercury pollutions? - Mercury is produced from industries such as coal-fired power plants, chemical manufacturing, and cement production.
3. Do you thing coal-fired power plants, chemical manufacturers and cement producers should adopt Lin Zang’s device? Justify your
