Metal-organic framework-activated carbon composite materials for the removal of ammonia from contaminated airstreams

L.N.M and R.E.M wish to acknowledge the financial support from the EPSRC industrial CASE award (grant EP/N50936X/1). A.T and G.B would like to thank the financial support from the Fondo per il finanziamento delle attività base di ricerca (grant PJ-RIC-FFABR_2017).Metal-organic frameworks (MOFs) are a class of porous materials that show promise in the removal of Toxic Industrial Chemicals (TICs) from contaminated airstreams, though their development for this application has so far been hindered by issues of water stability and the wide availability and low cost of traditionally used activated carbons. Here a series of three MOF-activated carbon composite materials with different MOF to carbon ratios are prepared by growing STAM-17-OEt crystals inside the commercially available BPL activated carbon. The composite materials display excellent water stability and increased uptake of ammonia gas when compared to unimpregnated carbon. Such properties make these composites very promising in the fields of air purification and personal protective equipment.PostprintPeer reviewe

Note and Comment

The Basis of Relief from Penalties and Forfeitures - The equitable principle of relief from penalties and forfeitures is so far elementary as almost to defy analysis. Many, perhaps most, of the judicial explanations of the principle have based it upon interpretation or construction, appealing to the doctrine that equity regards intent rather than form. Yet a logical application of this doctrine would lead to results very different from those which have actually been arrived at in the decisions. Thus, a stipulation in a mortgage that the mortgagor waives his equity of redemption can hardly be interpreted as meaning that he does not waive it, yet all such stipulations are ignored and redemption granted, nevertheless. Again, a penalty for breach of contract cannot be saved by the most solemn declaration that it is intended as liquidated damages. It must be conceded that many cases have actually been, decided on the interpretation theory, producing such enormities as Iowa Land Co. v. Mickel, 41 Ia. 4o2 (sale of land, $15a out of$6oo paid, $4ooo in improvements, second instalment of$150 one day late due to a misunderstanding; held forfeited), and Doctornan v. Schroeder, 114 AUt. 8io (N. J., 1921; sale of land, $IOOO paid, last instalment of$iooo thirty minutes late; held forfeited). But such cases represent the minority view, and one applicable only to instalment sales, no court pursuing this course in mortgage or liquidated damage cases
