Carbon nanotube (CNT) membranes were employed as the active element of a switchable transdermal drug delivery device that can facilitate more effective treatments abuse and addiction. Due to dramatically fast flow through CNT cores, high charge density, small pore dimensions, highly efficient electrophoretic pumping functionalized membrane was achieved. These integrated with nicotine formulation obtain rates on human skin (in vitro) are consistent Fickian diffusion in series model. The able...

Abstract The fouling behavior of carbon nanotube (CNT) membranes is investigated for large protein biomolecules and a wide variety small molecules. CNT are largely resistant, even to untreated river water, due size exclusion an inert graphitic core that supports fast fluid flow. However, it found bovine serum albumin (BSA) naphthalene significantly foul solution coagulation π – stacking, respectively. Small single‐walled (SW) CNTs (<1.5 nm i.d.) difficult with BSA when precipitation...

Carbon nanotube membranes with inner diameter ranging from 1.5–7 nm were examined for enhanced electroosmotic flow. After functionalization via electrochemical diazonium grafting and carbodiimide coupling reaction, it was found that neutral caffeine molecules can be efficiently pumped electroosmosis. An velocity as high 0.16 cm s−1 V−1 has been observed. Power efficiencies 25–110 fold improved compared to related nanoporous materials, which important applications in chemical separations...

Use of sol–gel condensation reactions with the proper precursors, in conjunction electrospinning methods, leads to facile formation one-dimensional nanofibers silicon or germanium dioxide doped erbium. These nanowires are characterized by a combination scanning and transmission electron microscopies, energy dispersive X-ray analysis, FT IR spectroscopy, diffraction, photoluminescence spectroscopy. By comparing such structures comparably sized erbium oxide (Er2O3), influence matrix...

Silicon nanowires (Si NWs), one-dimensional single crystalline, have recently drawn extensive attention, thanks to their robust applications in electrical and optical devices as well the strengthening of diamond/SiC superhard composites. Here, we conducted high-pressure synchrotron diffraction experiments a diamond anvil cell study phase transitions compressibility Si NWs. Our results revealed that onset pressure for I−II transformation NWs is approximately 2.0 GPa lower than previously...

Electrophoretic transport of proteins across electrochemically oxidized multi-walled carbon nanotube (MWCNT) membranes has been investigated. A small charged protein, lysozyme, was successfully pumped MWCNT by an electric field while rejecting larger bovine serum albumin (BSA). Transport lysozome reduced a factor about 30 in comparison to bulk mobility and consistent with the prediction for hindered transport. Mobilities between 0.33 1.4 × 10−9 m2 V−1 s−1 were observed are approximately...

Alloy electrode material like tin dioxide (SnO2) possesses much higher specific capacity as compared to commercial graphite anode in lithium ion battery (783 vs 372 mAh g–1). However, the huge volume change (260%) of SnO2-based during alloying and dealloying process can cause significant pulverization rapid loss. Herein we report synthesis SnO2 asymmetric membranes via a unique combination phase inversion sol–gel chemistry overcome this big challenge. The membrane demonstrates 500 g–1 based...

One-dimensional nanofibers of tin oxide doped with erbium can be readily prepared by a combination sol gel condensation processing and electrospinning. Such structures are strongly emissive in the near-infrared at 1540 nm whose intensity is directly proportional to concentration. A electron microscopies, selected area diffraction, X-ray diffraction reveal polycrystalline structure for given one-dimensional nanofiber whereby influences nanocrystal feature size.

The United States is by far the largest corn producer worldwide, with yields steadily increasing for past decades. In many midwestern U.S. states such as Iowa, Illinois, and Nebraska, farmers currently grow more than consumers can utilize human food or animal feed. To sustain economic viability of farmers, it critical that new uses markets corn, byproducts from harvesting, industrial products, processing should be discovered, giving highest return to producers. With popularity electric...
