From a deep eutectic mixture consisting of trimethylammonium chloride (TMACl) and oxalic acid, two templated zirconium phosphates, ZrPOF-TMA1 with 8- and 10-ring pore channels as well as ZrPOF-TMA2 with 7- and 8-ring pore channels, have been synthesized. A low P/Zr ratio is necessary for ZrPOF-TMA1, and higher P/Zr ratios tend to form ZrPOF-TMA2, but the former cannot be obtained by templating ...

Mesoporous carbon materials were synthesized employing polymers and silica gels as structure directing templates. The basic physico-chemical properties of the synthetic mesoporous materials were characterized by (1)H and (13)C MAS solid-state NMR, X-ray diffraction, transmission electron microscopy (TEM) and nitrogen adsorption measurements. The confinement effects on small guest molecules such...

T HE PENETRATION of capillary walls by water and dissolved substances appears to take place solely by processes which require no energy transformations on the part of the capillary endothelial cells. The rate of net fluid movement across the capillary wall has been shown to be simply proportional to the difference between hydrostatic and osmotic forces acting across the capillary membranes (I, ...

Despite the introduction of selenic acid for anodic porous alumina (APA) preparation with small nanopore diameters (< 20 nm), no attempt has been made to use it in fabrication small-diameter magnetic and metallic nanowire arrays. In this paper, considering high cost acid, attempted initially oxalic an ordered pattern first anodization step then employ second by matching appropriate voltage. By ...

Objective(s): In this work, pomegranate juice was used as a capping agent for self- assembly to form particles-like Au nanostructures in the presence of AuHCl4.3H2O as aurate source. Besides, to investigate the concentration effect of pomegranate juice as the green capping agent on the morphology and particle size of final products several experiments were...

Spherical mesoporous silica MCM-41 was synthesized for adsorptive removal of sulfur compounds from fossil fuels using 1mM solution of dibenzothiophene (DBT) in dodecane as model oil. The prepared silica adsorbent has been characterized by nitrogen adsorption-desorption analysis as well as Small Angle X-ray Scattering (SAXS), and transmission and Scanning Electron Microscopy (SEM) methods. R...

Porous anodic alumina (PAA) has been intensively studied in past decade due to its applications for fabricating nanostructured materials. Since PAA's pore diameter, thickness and shape vary too much, a systematical study on the methods of morphology characterization is meaningful and essential for its proper development and utilization. In this paper, we present detailed AFM, SEM and TEM studie...

The limitations of current grafting materials have driven the search for synthetic alternatives to cancellous bone. A variety of biodegradable polymer foams composed of poly(lactide-coglycolide) [PLAGA] have been evaluated for such uses. However, structural limitations may restrict the clinical use of these scaffolds. We have developed a sintered microsphere scaffold composed of 85:15 poly(lact...

In this letter, the uniform 4H silicon carbide (SiC) mesopores was fabricated by pulsed electrochemical etching method. The length of the mesopores is about 19 μm with a diameter of about 19 nm. The introduction of pause time (T off) is crucial to form the uniform 4H-SiC mesopores. The pore diameter will not change if etching goes with T off. The hole concentration decreasing at the pore tips d...
