pH Sensitive Anticancer Prodrug: Amide of Kemp's Acid [PDF]

, 2009
Solid tumours are characterised by lower extracellular pH (as low as 5.8 pH) compared to normal healthy cellular pH (actively regulated at pH 7.3). This difference may be exploited with an acid-sensitive anti-tumour prodrug which releases a cytotoxin ...

Bis(μ-2′-carboxylatobiphenyl-2-carboxylic acid-κ2O2:O2′)bis[(2,2′-bipyridine-κ2N,N′)(2′-carboxylatobiphenyl-2-carboxylic acid-κO2′)zinc(II)]

Acta Crystallographica Section E, 2009
In the dimeric title compound, [Zn2(C14H9O4)4(C10H8N2)2], the ZnII ions are pentacoordinated by one 2,2′-bipyridyl ligand and by three O atoms from three 2′-carboxylatobiphenyl-2-carboxylic acid ligands.

Electrostatic Superlattices Beyond 1:1 Stoichiometry

Advanced Functional Materials, EarlyView.
Polymer‐mediated charge regulation drives two hierarchical routes to higher‐stoichiometry nanoparticle superlattices. Tuning the polymer's molecular weight promotes progressive interstitial filling, transforming ZnS into the fully occupied CaF2${\rm CaF}_2$ lattice. Exchanging polymer assignment between large and small nanoparticles instead breaks CsCl

Mono‐Material Polydisulfides for Pressure Sensitive Adhesive Tapes With Closed‐Loop Recyclability

Advanced Functional Materials, EarlyView.
A high‐performance pressure‐sensitive adhesive (PSA) tape is developed where both the adhesive layer and plastic backing layer can be recycled back to monomer in a closed‐loop cycle. Both layers of the tape are composed of analogous polydisulfide copolymers using only two unique monomers, thus giving it a mono‐material design and enabling recycling of ...

Carboxylic Acid Production [PDF]

, 2018
Carboxylic acids are truly central compounds in cellular metabolism. Carbon dioxide is captured from the atmosphere through formation of carboxylic groups and is also released, in part, by decarboxylation reactions. The reactivity of the carboxylic group
