By definition, a crystalline solid, also simply known as a crystal, is a solid material whose basic constituents such as atoms, ions, and molecules are arranged in a highly ordered and well-defined microscopic structure, known as a crystal lattice. These solids are formed in a process known ...
In conclusion, we demonstrate HD in both amorphous and crystalline solids including chiral systems. HD in the condensed phase provides valuable information on chirality. Conventional solid-state chiroptical techniques such as CD have poor efficiency because the chiral signal is weaker than the artifact ...
The present invention provides a (-) - a crystalline solid and amorphous halo Dove ester form. 所述结晶固体形式可用在各种药物组合物中,对于预防和/或治疗与哺乳动物的血脂沉积相关的情况,尤其是涉及2-型糖尿病和高血脂的哪些疾病特别有效. The crystalline solid form can be used in various pharmaceutical...
Amorphous materials are one kind of nonequilibrium materials and have become one of the most active research fields. Compared with crystalline solids, the
Blend compatibility study by solid-state 13C nuclear magnetic resonance Thus, besides the crystalline phase of HDPE, the blends show two amorphous phases: one rich in the polyolefin and the other rich in the low-molecular-... MIB Tavares,LC Mendes - 《Polymer Testing》 被引量: 30发表: 2000...
Amorphous solid dispersion (ASD) is a widely employed formulation technique for drugs with poor aqueous solubility. Polymers are integral components of ASDs, but mechanisms by which polymers lead to the generation and maintenance of supersaturated soluti
An ion-implanted mica solid state track recorder so produced is then exposed to neutrons,... FH Ruddy - US 被引量: 21发表: 1988年 Assessment by optical coherence tomography of a Brazilian biodegradable polymer-coated sirolimus eluting stent vs a biolimus A9-eluting stent in porcine coronary ...
the DSC experiments. This effect can be also explained by “amorphous-amorphous” transition, using Peierls distortion mechanism proposed for PCMs as interplay between the short and long bonds, which ratio determines the electronic gap58. Crystalline reflexes appeared in the XRD pattern of thin films...

This system shows an extremely intense phosphorescence, with a quantum yield of >95% in the solid state. Both the emission color and thermal stability vary due to changing counter ions (Cl− vs. OTf−). Of particular note is the thermal crystalline-amorphous-crystalline transformation for ...
