Transmission electron microscopyTransmission electron microscopy (TEM) is a microscopy technique in which a beam of electrons is transmitted through a specimen to form an image. The specimen is most often an ultrathin section less than 100 nm thick or a suspension on a grid. An image is formed from the interaction of the electrons with the sample as the beam is transmitted through the specimen. The image is then magnified and focused onto an imaging device, such as a fluorescent screen, a layer of photographic film, or a sensor such as a scintillator attached to a charge-coupled device.
CrystalA crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions. In addition, macroscopic single crystals are usually identifiable by their geometrical shape, consisting of flat faces with specific, characteristic orientations. The scientific study of crystals and crystal formation is known as crystallography.
TaoTao or Dao (道) is the natural order of the universe, whose character one's intuition must discern to realize the potential for individual wisdom, as conceived in the context of East Asian philosophy, East Asian religions, or any other philosophy or religion that aligns to this principle. This seeing of life cannot be grasped as a concept. Rather, it is seen through actual living experience of one's everyday being. Its name, Tao or Dao , came from Chinese, where it signifies the way, path, route, road, or sometimes more loosely doctrine, principle, or holistic belief.
Hydrothermal synthesisHydrothermal synthesis includes the various techniques of crystallizing substances from high-temperature aqueous solutions at high vapor pressures; also termed "hydrothermal method". The term "hydrothermal" is of geologic origin. Geochemists and mineralogists have studied hydrothermal phase equilibria since the beginning of the twentieth century. George W.

Phase problemIn physics, the phase problem is the problem of loss of information concerning the phase that can occur when making a physical measurement. The name comes from the field of X-ray crystallography, where the phase problem has to be solved for the determination of a structure from diffraction data. The phase problem is also met in the fields of imaging and signal processing. Various approaches of phase retrieval have been developed over the years. Light detectors, such as photographic plates or CCDs, measure only the intensity of the light that hits them.
Tao Te ChingThe Tao Te Ching (UKˌtaʊ_tiː_ˈtʃɪŋ, USˌdaʊ_dɛ_ˈdʒɪŋ; AUDChinese-TaoTeChing.oggdao4-de2-jing1) is a Chinese classic text and foundational work of Taoism written around 400 BC and traditionally credited to the sage Laozi, though the text's authorship, date of composition and date of compilation are debated. The oldest excavated portion dates back to the late 4th century BC, but modern scholarship dates other parts of the text as having been written—or at least compiled—later than the earliest portions of the Zhuangzi.
