due to equilibrium between two molecular species‚ acid-base‚ keto-enol‚ lactim-lactam‚ or between stereoisomer or between crystal structures. This type of thermochromism has various applications for fiber optical science‚ photo storage instrument‚ optical sensor‚ and so on. We can divide three parts on the basis of materials (1) Variation in Crystal Structure (liquid crystal) (2) Stereoisomer (3) Molecular Rearrangement Advantages of organic compound thermochromism are that color change takes

Analysis “Hobnail” by Crystal Arbogast The author of the story is Crystal Arbogast. She is an American famous writer. She was born in Wise County‚ Virginia. And the events of the story take place also there. She did not start writing stories until she was 40 years old. Crystal Arbogast is well-known for her short stories. The story is entitled “Hobnail”. The title doesn’t reveal the theme and the idea of the story. I want to say‚ that I had several ideas what the story would be about before reading

the α- phase‚ and in the β phase the lattice symmetry is hexagonal. As for SiO2‚ the lattice symmetry is trigonal. The lattice symmetry of FePO4 in the α- phase and SiO2 is similar as 2 silicon atoms can replace 1 iron and 1 phosphorus atom in the crystal structure. Looking at this stoichiometric equation‚ Fe3+ + P5+ 2Si4+‚ we can see that there are 2 atoms on both side of the equation and total charge on both sides is equal‚ therefore both SiO2 and FePO4 in the α- phase have a similar lattice symmetry

was living a poor area with "boards torn up" (5)‚ "no carpet on the floor" (6). All these made the mother more real in a real life. Hughes used metaphor in his poem to show us that the mother didn’t have a smooth life by "life for me ain’t been no crystal stair." (2‚20) She must have had rough times during her life and told her son that life is not that easy‚ smooth but she overcame it with "I’se been a-climbin’ on" (9)‚ "I’se still goin" (18) in order for him to be prepared for whatever good or bad

3. Why was the Great Exhibition of 1851 so important for Britain? (12) The Great Exhibition was Britain on display to the rest of the world. It showed the rest of the world how superior Britain was in the many industries which British manufactures has been the first to develop‚ so showed off the best of Britain to the rest of the world which the British could be very proud of. Although Britain wasn’t perfect it focused on the best thing about Britain. The Great Exhibition
