mard-abad calc-alkaline granite formed along the margin of active pull-apart or intra-continental plates, and it is post-collision granite type. granophyric, perthitic and myrmekitic are main textures that could form from crystallization of hypersolvus source magma, which occurred under water vapor pressure of approximately 2 kb. during this study the temperature of formation of these granites ...

This paper reports a composite microfluidic system for performing protein crystallization trials in nanoliter aqueous droplets inside capillaries suitable for X-ray diffraction and the evaluation of the quality of the crystals directly by on-chip X-ray diffraction. Crystallization conditions can be screened with both microbatch and vapor-diffusion techniques by eliminating evaporation of soluti...

This work identifies unknown crystals found encrusting the Marcellus Shale Formation at the Mapleton Quarry locality in Central Pennsylvania, over the course of a month. The outcrop has been exposed for sufficient time for there to be advanced chemical weathering, allowing for the presence of secondary minerals to form and changes in the composition of the surrounding water table and environmen...

?-Calcium sulfate hemihydrate (?-HH) is an important cementitious material, which can be prepared by hydrothermal method from calcium dihydrate (DH) in electrolyte solution. Study of the conversion kinetics DH to ?-HH NaCl solution helpful for understanding control process. In this paper, X-ray diffraction (XRD) patterns were applied study effect temperature on crystallization determine kinetic...

We report a new class of crystallization-induced red-emitting luminogen based on a synthetic biodegradable indigo derivative, Indigoid-B. This compound, upon an ultrasonic treatment, formed well-defined microcrystals that showed striking crystallization-induced emission (CIE) in mixed solvents of tetrahydrofuran-water.

The term “karst” applies to a distinctive type of landscape that develops from the dissolving action of water on soluble bedrock (Figure 11.1)—primarily limestone and marble but also dolostone, gypsum and halite. Karst landscapes are characterized by fluted and pitted rock surfaces, shafts, sinkholes, sinking streams, springs, subsurface drainage systems, and caves. The unique features and thre...

Gypsum is a kind of important nonmetallic mineral resources which is widely used in various sectors of the national economy, especially as the main and new raw material for building. The quantity of natural gypsum in Tai’an is very rich, and most of them are large deposit of recoverable ones with about 36 billion tons in total. The rich natural resources of Tai'an will undoubtedly play a decisi...

An optimal small amount of water added into methyl ammonium iodide (MAI) solution in isopropyl alcohol (IPA) helps perovskite crystallization and leads to larger grain size from sequential deposition of perovskite films. The concentration of water was varied from 1% to 7% (vol% of IPA) in MAI solution and optical absorption, crystallization, morphology of perovskite films and their photovoltaic...

STATEMENT OF PROBLEM Resinous die materials have several important advantages including strength, abrasion resistance, and detail reproduction. Despite these advantages, the shrinkage of resinous die materials during polymerization has limited their widespread acceptance. PURPOSE This study determined whether a retarded setting reaction could improve the accuracy of an epoxy resin die system,...

High-pressure X-ray diffraction was carried out on a single crystal of gypsum compressed in a diamond anvil cell. The sample maintained its crystal structure up to 4.0 ± 0.1 GPa. The fit of pressure dependence of the unit-cell volume to the third-order Birch-Murnaghan equation yielded KT0 = 44(3) GPa and (∂KT/∂P)0 = 3.3(3), where KT0 and (∂KT/∂P)0 are the isothermal bulk modulus and its pressur...
