“…19 The rearrangement causes the microregion to be highly ordered on the microscopic scale, which results in forming abundant likemicrocrystals where the grain boundary phenomenon occurs, accounting for particular polycrystalline electron diffraction patterns. 20 Nevertheless, if illuminated by high-energy electron beams, the diffraction patterns will disappear with the reexcitation, as this crystal formation is not stable enough.…”

This paper reports the study of a novel mesoporous material modified from natural clinoptilolite (NC) through pore broadening and organic modification. In order to reveal purification capacity enhancement, micrographs obtained by performing high-resolution transmission electron microscopy on the materials were used to compare the inner structures of NC and mesoporous clinoptilolite (MC) at various magnifications. In MC, broader pores (from microporous to mesoporous) at the surface of MC and sublimation clouds of particles inside the pores and channels were found, while NC exhibited none of these features. The results obtained from energy-dispersive X-ray spectroscopy analysis indicate that the contents of impurities in MC were lesser than that of NC; the crystallinity of MC was also found to be more than that of NC. The decolorization rate of the MC material can reach up to 98·6%, while that of NC is 87%, and the removal rates of MC's chemical oxygen demand as analyzed by the dichromate method (COD Cr ) can reach 91·3%, while the rate for NC is 56%. The results indicate that the MC material has better adsorption with some mesoporous level (2-50 nm) on soluble organics, which is related to the pore diameter and the framework of the MC material from wastewater.

“…This includes the removal of heavy metals from soils and water streams [122,123] or the ability to bind pathogens in order to remove them from wastewater treatment plants, thus including sludge activity [124,125]. The outstanding relevance of zeolites is further illustrated by the number of reviews and research papers available in the literature covering topics as diverse as their use in catalysis (with reviews dating back to 1971 [126,127]), pollution control [128], electrochemistry (zeolites may act as electrode modifiers due to their ion-exchange and size selectivity capability) [129], photocatalysis [130], thin film technology for applications as membranes and electronic devices [131][132][133][134][135], or pharmaceutical applications [136].…”

This paper will introduce the reader to some of the “classical” and “new” families of ordered porous materials which have arisen throughout the past decades and/or years. From what is perhaps the best-known family of zeolites, which even now to this day is under constant research, to the exciting new family of hierarchical porous materials, the number of strategies, structures, porous textures, and potential applications grows with every passing day. We will attempt to put these new families into perspective from a synthetic and applied point of view in order to give the reader as broad a perspective as possible into these exciting materials.

“…Highly elastic silicon and, in contrast, soft polymer cantilevers were implemented to chemical sensors with resonance shift assay [1][2][3]. To date, the determination of trace amounts of adsorbed biological, chemical and other multiplex substances through micromechanical sensing still holds a tremendous potential [4][5][6][7][8]. To improve the shifts of the resonant frequency one needs to enlarge the active surface area of the sensor while preserving its mechanical stiffness.…”

We present here the behavior of the resonance frequency of porous anodic alumina cantilever arrays during water vapor adsorption and emphasize their possible use in the micromechanical sensing of humidity levels at least in the range of 10-22%. The sensitivity of porous anodic aluminium oxide cantilevers (Δf/Δm) and the humidity sensitivity equal about 56 Hz/pg and about 100 Hz/%, respectively. The approach presented here for the design of anodic alumina cantilever arrays by the combination of anodic oxidation and photolithography enables easy control over porosity, surface area, geometric and mechanical characteristics of the cantilever arrays for micromechanical sensing.1332
