3. Hydrogen peroxide - Wikipedia

   en.wikipedia.org/wiki/Hydrogen_peroxide

   Hydrogen peroxide ( H2O2) is a nonplanar molecule with (twisted) C 2 symmetry; this was first shown by Paul-Antoine Giguère in 1950 using infrared spectroscopy. [9] [10] Although the O−O bond is a single bond, the molecule has a relatively high rotational barrier of 386 cm −1 (4.62 kJ / mol) for rotation between enantiomers via the trans ...

4. Hydrogen damage - Wikipedia

   en.wikipedia.org/wiki/Hydrogen_damage

   Hydrogen picked up during melting and casting segregates at internal voids and discontinuities and produces these defects during forging. Fish-eyes are bright patches named for their appearance seen on fracture surfaces, generally of weldments. Hydrogen enters the metal during fusion-welding and produces this defect during subsequent stressing.

5. Cleaner fish - Wikipedia

   en.wikipedia.org/wiki/Cleaner_fish

   Cleaner fish. Cleaner fish are fish that show a specialist feeding strategy [1] by providing a service to other species, referred to as clients, [2] by removing dead skin, ectoparasites, and infected tissue from the surface or gill chambers. [2] This example of cleaning symbiosis represents mutualism and cooperation behaviour, [3] an ecological ...

6. Magnet fishing - Wikipedia

   en.wikipedia.org/wiki/Magnet_fishing

   A pair of bolt cutters collected through magnet fishing in the Scarpe at Lallaing, France. A neodymium magnet used for magnet fishing. Magnet fishing, also called magnetic fishing, is searching in outdoor waters for ferromagnetic objects available to pull with a strong neodymium magnet. [1] Recovered items may be dangerous, such as firearms ...

7. Fishing sinker - Wikipedia

   en.wikipedia.org/wiki/Fishing_sinker

   A fishing sinker or plummet is a weight used in conjunction with a fishing lure or hook to increase its rate of sink, anchoring ability, and/or casting distance. Fishing sinkers may be as small as 1 gram (0.035 oz) for applications in shallow water, and even smaller for fly fishing applications, or as large as several pounds (>1 kg) or ...
