Zeolites have found tremendous applications in the chemical industry. However, dynamic nature of their active sites under flow adsorbate molecules for adsorption and catalysis is unclear, especially operando conditions, which could be different from as-synthesized structures. In present study, we report a structural transformation adsorptive SAPO-34 zeolite by using acetone as probe molecule va...

Methanol-to-olefin (MTO) catalysis is a very active field of research because there is a wide variety of sometimes conflicting mechanistic proposals. An example is the ongoing discussion on the initial C-C bond formation from methanol during the induction period of the MTO process. By employing a combination of solid-state NMR spectroscopy with UV/Vis diffuse reflectance spectroscopy and mass s...

Mesoporous aluminophosphate thin films templated by nonionic copolymer surfactant (Pluronic-F108 and –F127) were prepared by the dip-coating method. Self-assembly of copolymer surfactants with different sizes and hydrophilic properties into cubic symmetry causes the formation of thin films with different pore dimensions. Symmetry of pore arrangement was determined by SAXS and TEM measurements. ...

Objectives: To investigate the relationship between foot posture and plantar arch among adolescent wearers and non-wearers of high-heeled shoes. Methods: Thirty-six female adolescents aged 13 to 20 years were selected and grouped as 16 high-heel nonwearers and 20 high-heel wearers. Foot posture was analyzed using photos, firstly barefoot and, secondly, after wearing previously standardized high...
