Crystalline Porous Organic Salts: Crystalline Porous Organic Salts: From Micropore to Hierarchical Pores (Adv. Mater. 44/2020)

Highly Porous Activated Carbons Derived from Poly(styrene Sulfonic Acid) Based Organic Salts

The objective of this paper is to study the effect of transition metals used in organic salts on the structural properties of carbonaceous materials. To accomplish our objectives, we carbonized commercially available poly(styrene sulfonic acid-co-maleic acid), sodium salt. To study the effect of metals, sodium was exchanged with either cobalt, nickel, or iron. Park and Jung [1], and Putyera et ...

Buckled crystalline structure of mixed ionic salts.

X-ray absorption ne structure (XAFS) measurements of mixed salts Rb x K 1?x Br and RbBr y Cl 1?y at their congruent melting points compositions reveal that their actual structure buckles about the NaCl average structure with an rms angular deviation from collinearity of 7-9. XAFS measures the buckling directly through three body correlations, and veriies the homogene-ity and randomness of the m...

Screening for crystalline salts via mechanochemistry.

Neat grinding and solvent-drop grinding methods are found to be effective screening tools for indicating the potential for crystalline salt formation involving a given acid-base pair, as demonstrated with two model pharmaceuticals.

Diffusion in porous crystalline materials.

The design and development of many separation and catalytic process technologies require a proper quantitative description of diffusion of mixtures of guest molecules within porous crystalline materials. This tutorial review presents a unified, phenomenological description of diffusion inside meso- and micro-porous structures. In meso-porous materials, with pore sizes 2 nm < d(p) < 50 nm, there...
