Insights into the Mechanochemical Synthesis of MOF-74

DFT insights into the adsorption of NH3-SCR related small gases in Mn-MOF-74.

Mn-MOF-74 has great potential to catalyze selective catalytic reduction (SCR) reaction with NH3 being the reductant (NH3-SCR). However, the reaction mechanism, in particular the adsorptive properties of key reactive species in Mn-MOF-74, remains ambiguous. Besides, the effects of impurities such as H2O and SO2 on the process need further investigation. In this paper, based on density functional...

Mechanochemical synthesis of alumina nanoparticles

Abstract: Nano- size alumina particles have been synthesized by mechanical activation of a dry powder mixture of AlCl3 and CaO. Mechanical milling of the above raw materials with the conditions adopted in this study resulted in the formation of a mixture consisting of crystalline CaO and amorphous aluminum chlorides phases. There was no sign of chemical reaction occurring during milling stag...

Newer Insights into the Prsevention of the Common Cold

Since most colds are self-limiting, symptoms will usually resolve on their own in seven to ten days. For the majority of patients, treatment is symptomatic and targeted at the most bothersome symptoms. Specific nonprescription therapy may relieve cold symptoms but should be used with caution, especially in at-risk patient populations. Patients should monitor for worsening symptoms, and progress...

In silico design and screening of hypothetical MOF-74 analogs and their experimental synthesis

a ligand in MOF-74, and thin black lines abstract connections within a single SBU rod. (a) View of the ab face of etb net. (b) View of the bc face of the etb net. Crystal structure assembly The etb net of MOF-74, visualized in Fig. 4, exhibits special complexities which preclude the use of previously developed methods for in silico crystal design. Three distinct problems arise. Firstly, not all...
