31 Fantastic electron microscope images of objects looking very suggestively like fossilized living forms again captured the imagination of the world.

32 The non-crystallographic symmetry was established from the electron density and heavy atom sites.

33 Like the electron, the muon acts like a tiny bar magnet.

34 Increasingly U-series dates are being used in conjunction with electron spin resonance dates using the same materials.

34 Wish you can benefit from sentencedict.com and make progress everyday!

35 The mean distance of the electron from the central proton defines the atom's size.

36 When the sheet is examined in the electron microscope filaments are seen to be localized at the upper surface.

37 He saw that if an electron could occupy any orbit round a nucleus then a spiralling collapse was inevitable.

38 When an electron collides with a positron the two particles disappear, or annihilate, to create a high-energy photon.

39 Their electron traps are bleached during transport but after sedimentation and burial they begin to accumulate electrons once more.

40 Negative ions can also be formed when an atom has an extra electron bolted on.

41 The growth rate was established by flow cytometry and the morphological characteristics of the growing cells by electron microscopy.

42 Crystal cleanliness and crystallinity were checked by Auger electron spectroscopy and low energy electron diffraction, respectively.

43 I strongly recommend the book to anyone in any field who is interested in using electron microscopy.

44 If we remove an electron from a bonding orbital, the bond in the ion is weaker than that in the molecule.

45 Two phasing methods were used to obtain electron density maps.

46 The vertical bars show the region of H5 that has been built in the electron density map.

47 In fact, breaking one of the bonds, by pulling an electron out of it, requires a lot of energy.

48 In electron sharing, a shared electron can not be considered to have been gained or lost.

49 Advantest jumped 5.4 per cent to 11,520 and Tokyo Electron surged 4.8 per cent to Y7,050.

50 Over the past 10 years Philips Analytical has grown and diversified away from its core technologies of X-ray analysis and electron microscopy.

51 Mike Stewart's morphological methods, however, could go beyond those of light microscopy to that of the electron microscope.

52 The second half of the chapter introduces electron diffraction with a focus on transmission electrons.

53 Electron transfer to or from the node is only through the tunnel junction.

54 It is complementary to low energy electron diffraction, which probes long range order - ie a minimum domain size of 100-200A/9.

55 To take a simple example, the important subatomic particle called the electron has a negative electrical charge.

56 Donor and acceptor compounds are differentiated by the direction of the electron transfer to or from the carbon layers.

57 If heat is applied, the electron may be able to escape from the deep trap.

58 This process involves the addition of microorganisms, nutrients and an electron acceptor into the saturation zone of a contaminated aquifer.

59 To the joy of jewellers visible light has too low a frequency to excite an electron in a perfect diamond.

60 Extensive facilities for evaluation of catalytic activity include Auger electron spectroscopy and diffuse reflectance and transmission Fourier transform infrared spectroscopy.
