What's the difference between spherolithe and spherulite?
Spherolithe
Definition:
Example Sentences:
(1) Anisotropic structures can be observed either at the periphery of the dendrites or isolated as small spheroliths.
(2) The initial stage is characterized by a periductally lymphocytic infiltration, ectasias of the ducts, and alteration of the secret in the duct lumens (spheroliths, microliths).
(3) It was found that admixtures of urea, creatinine, potassium and, possibly, sodium contained in the urine of patients initiate the formation of copper chloride crystals of different sizes, their shape changes, dendritic and spherolithic crystallization occurs.
(4) Laser microprobe mass analysis was applied to study the chemical composition of spheroliths in the Bowman's membrane of patients suffering from primary atypical bandkeratopathy.
(5) Characteristic congophilic laminated spheroliths are present within the cystic spaces.
Spherulite
Definition:
(n.) A minute spherical crystalline body having a radiated structure, observed in some vitreous volcanic rocks, as obsidian and pearlstone.
Example Sentences:
(1) Textures observed include spherulites with Maltese crosses, striated and highly colored ribbons, whorls of periodic interference fringes, and colored flakes.
(2) Analytical scanning electron microscopy and x-ray diffraction disclosed that well-crystallized brushite is the major compound of the spherulites.
(3) Histologic examination showed that the spherulites remain in situ and become embedded within the new growth of fibrous tissue, collagen and new bone.
(4) The changes that occur in the pattern of long-range order during the growth of these structures are typical of the development of the spherulitic crystal habit in numerous other materials of nonbiological origin.
(5) The remaining, resistant polysaccharides showed up in the form of optically positive spherulites indicating radially oriented dye molecules on a circularly ordered, micellar polysaccharide texture.
(6) These observations suggest that further consideration should be given to a phlogistic role for similar spherulites found in some patients.
(7) In the surface and the bulk of PU[PTMG,c-(Ser)2,MDI] film, spherulite structures were developed when the molecular weight of the PTMG segment was high, while single crystals with a length of 3-4 microns were produced when the molecular weight of the PTMG segment was low.
(8) Some of the acellular material, particularly that on the IUD side of the crust, was organized in spherulitic crystals and was identified as calcium phosphate by x-ray microanalysis.
(9) The main islet showed a central X-ray translucent region and outer calcified layers which could be subdivided into 2 types; those with spherulitic calcification and those with smooth calcification.
(10) A third type of calcification was observed in which rhombic crystals were associated in a spherulitic pattern.
(11) Depending on crystallization conditions, they appeared as well-formed individual crystals or as spherulites.
(12) This study was undertaken to investigate the mineral phase of spherulitic calcifications discovered in the pulpous mesenchyme of human primary molars by microradiography.
(13) They can form birefringent nematic liquid crystals (tactoids) and spherulites.
(14) In this mechanism, each spherulitic domain of polymers is considered to be initiated by a single homogeneous nucleation event.
(15) This induced light and electron microscopic findings very similar to those seen in acute or chronic arthritis, not attributable to any mechanism other than to spherulites, in humans.
(16) Surface mineral deposits were composed of granular spherulites, which contained both calcium and phosphorous.
(17) The melting behaviour of highly crystalline spherulites, of a short chain amylose DP-15 corresponding to both the A and B polymorphs of starch has been studied as a function of water content.
(18) The gelation of sickle hemoglobin includes the formation of spherulitic arrays of polymers, known as polymer domains, which are an intrinsic result of the polymer formation mechanism.
(19) In these polyetherurethanes, spherulites, fibrous structures, and needle-like crystals were formed according to the conditions used.
(20) DNA crystals usually take the form either of spherulites up to 100 mu in diameter or of needles with the length up to 50 mu.
