Chemical and morphological characteristics of inorganic sorbents with respect to gas adsorption... 

The surface chemical and morphological characteristics of inorganic sorbents such as silicas, aluminas, talc, micas define both their chemical and physical adsorption potentials (surface energy). But the existence of mineral and organic surface pollutants will indeed strongly influence those properties. 

Advanced analytical methods enable an in-depth study of chemical and morphological characteristics of micro- and nanografted polymer materials. Often, the combination of several techniques is necessary to obtain a detailed picture. Investigations of simplified model systems such as nonstructured grafted surfaces, brushes produced on nonpoly-meric substrates, or selectively derivatized or stained samples are needed for comparison or as standards. Furthermore, the adaptation of biochemical and chemical assay techniques is useful to complete the picture of the produced structures and their functionalities. 

Powders are examined in their original form by dispersing them in either aqueous or nonaqueous mountants, depending on their solubility and dispersibility. The mounting media may include stains to increase the contrast of individual components for structural observation or discrimination on the basis of chemical and morphological characteristics. The detection of birefringence in powders is also useful for identification.

By the time the clinical program has entered phase 3, the sponsor should provide a full description of the physical, chemical, and biological characteristics of the drug substance. For example, most of the following should be evaluated and submitted solubility and partition coefficient, pKa, hygroscopicity, crystal properties/morphology, thermal evaluation, X-ray diffraction, particle size, melting point, and specific rotation stereochemical consideration. Proof...

It appears, therefore, that chemical structure as such has little bearing on whether or not molecules can be induced to fracture under tensile stress. This is determined rather by the amount of strain that can be imposed before fracture, by temperature and by the physical and morphological characteristics of the material. 

The unconsolidated mineral or organic material on the immediate surface of the earth that has been subjected to and shows the effects of genetic and environmental factors of climate (including moisture and temperature effects), and macro- and microorganisms, conditioned by relief, acting on parent material over a period of time. The soil produced from the combination of these factors differs from the parent material in many physical, chemical, and morphological properties and characteristics. ... 

Polymers are found in such a large variety of products that they have shaped modern life. The extraordinary versatility of polymers in terms of end-use properties is due to the variety and complexity of the microstructure of the polymeric material. The polymeric material includes both the polymer and the additives with which it is compounded. The microstructure of the polymeric material is determined by the molecular and morphological characteristics of the polymer itself, the way in which the polymer is processed and the additives used for compounding (Figure 1.1). The molecular characteristics of the polymer include chemical composition, monomer sequence distribution (MSD), molecular weight distribution (MWD), polymer architecture, chain configuration and morphology. 

Conducting polymer fibers were prepared by melt mixing and chemical coating on fibers. Different conductive materials were used in order to obtain conductive PP-based fibers with specific electrical and mechanical properties. The electrical conductivity and morphological characteristics of these fibers were investigated (Kim et al. 2004). The conductive fibers are intended for use in creating conductive yams, conductive fabrics (which can be used as electromagnetic shields), and multifunctional textile stractures for novel applications.
