Abstract Salt weathering can cause substantial deterioration of natural rocks, building stones, masonry materials, monuments, and engineering structures. Nearly two centuries salt studies, both theoretically empirically, have manifested its power as well complexity. This paper attempts to unite the kinds literature assess various theories in light combined information. The theoretical approache...

The influence of two structurally different anionic surfactants on the anhydrous-to-dihydrate transformation of carbamazepine (CBZ) was investigated. The surfactants studied were sodium lauryl sulfate (SLS), a surfactant commonly used in compendial dissolution methods, and sodium taurocholate (STC), an important surfactant in the solubilization and absorption of drugs and lipids in the gastroin...

Abstract On Mars, liquid water may form in regolith when perchlorate salts absorb vapor and dissolve into brine, or ice-salt mixtures reach their melting temperature thaw. Brines created this way can chemically react with minerals, alter the mechanical properties of regolith, mobilize soil, potentially create habitable environments. Although Martian brines would exist contact few studies have i...

Micro-scale, non-invasive, three-dimensional cross-sectional imaging of protein crystals was successfully accomplished using ultra-high resolution optical coherence tomography (UHR-OCT) with low noise, Gaussian like supercontinuum. This technique facilitated visualization of protein crystals even those in medium that also contained substantial amounts of precipitates. We found the enhancement o...

The synthesis and characterization of a Keggin-type mono-rhenium(V)substituted polyoxotungstate are described. The dimethylammonium salt [Me2NH2]4[PW11ReO40] was obtained as analytically pure homogeneous black-purple crystals by reacting mono-lacunary Keggin polyoxotungstate with [ReCl6] in water, followed by crystallization from acetone at ca. 5 °C. Single-crystal X-ray structural analysis of ...
