Superacids, defined as acids with a Hammett acidity function H0 ≤ -12, are useful materials, but a need exists for new, designable solid state systems. Here, we report superacidity in a sulfated metal-organic framework (MOF) obtained by treating the microcrystalline form of MOF-808 [MOF-808-P: Zr6O5(OH)3(BTC)2(HCOO)5(H2O)2, BTC = 1,3,5-benzenetricarboxylate] with aqueous sulfuric acid to genera...

HYPOTHESIS Abdominal compartment syndrome (ACS) is a morbid complication of damage-control laparotomy. Moreover, the technique of abdominal closure influences the frequency of ACS. DESIGN Retrospective cohort study. SETTING Urban level I trauma center. PATIENTS We studied 52 patients with trauma who required damage-control laparotomy during the 5 years ending December 31, 1999, and who su...

The continous flow reactor can synthesize MOF-808—an industrially relevant MOF—in 5 minutes compared to 48 hours in Batch, while maintaining crystallinity and porosity of the final product.

OBJECTIVE To evaluate the effectiveness of the Ministry of Food (MoF) cooking programme on self-reported food consumption and confidence with cooking. DESIGN A quantitative and qualitative evaluation of the MoF 8-week cooking course, using a pre-test/post-test study. Pre, post and 6-month follow-up quantitative outcomes were measured using self-administered questionnaires to record number of ...

Imidazole molecules were frequently incorporated into porous materials to improve their proton conductivity. To investigate how different arrangements of imidazoles in metal-organic frameworks (MOFs) affect the overall proton conduction, we designed and prepared a MOF-based model system. It includes an Fe-MOF as the blank, an imidazole@Fe-MOF (Im@Fe-MOF) with physically adsorbed imidazole, and ...

The Raman spectra of H2 and D2 adsorbed on metal–organic framework-5 at various pressures (H2: 12.8 and 30.3 bar; D2: 2.2– 24.5 bar) and temperatures (H2: 298 K; D2: 40–300 K) have been recorded. The shifts observed in the vibrational modes of the gases indicate that physisorption is responsible for the attractive interactions between the gas and the framework; these interactions are larger wit...
