The mechanism of formation anodic TiO2 nanotubes and the cause volume expansion are still controversial. It is well known that fluoride ions participate in field-assisted dissolution reaction as ejection to reduce current efficiency factor. Here, anodizing titanium an electrolyte with three different concentrations using four densities discussed detail. We found total nanotube array remained about same for a given current, being independent concentration NH4F (0.1, 0.3 0.5 wt%), depending...
Preeclampsia is a common, pregnancy-specific disease and major contributor to maternal foetal morbidity mortality. Some placental abnormalities, including deficient implantation, abnormal trophoblast cell function, improper vascular development, are believed lead preeclampsia. The long noncoding RNA SPRY4-IT1 more highly expressed in preeclamptic human placentas than normal placentas. We assessed the role of epithelial-mesenchymal transition (EMT)-associated invasion migration HTR-8/SVneo...
The formation mechanism of anodic TiO2 nanotubes remains controversial. To further explore the growth nanotubes, we compared difference between galvanostatic and potentiostatic anodizing processes, discovered that electric current kept dropping in final phase process, whereas voltage rising process. Therefore, so-called steady state field-assisted dissolution equilibrium model was not observed either Furthermore, during anodization, for first time diameters gradually increased from top to...
The fabrication and growth mechanism of TiO2 nanotubes have attracted widespread interest for decades. Conventional Ti anodization generally produces only non-split nanotubes. In this work, completely split nanotubes, whose morphology is similar to that porous anodic alumina, were produced under breakdown conditions. appearance so many in such a short period time (900 s) cannot be explained by the classical field-assisted dissolution theory, viscous flow model or equilibrium theory. Here, we...
Abstract Bacteriophage T7 RNA polymerase (T7 RNAP) is widely used for synthesizing molecules with synthetic modifications and unnatural base pairs (UBPs) a variety of biotechnical therapeutic applications. However, the molecular basis transcription recognition UBPs by RNAP remains poorly understood. Here we focused on representative UBP, 7-(2-thienyl)-imidazo[4,5-b]pyridine (Ds) pyrrole 2-carbaldehyde (Pa), investigated how hydrophobic Ds–Pa pair recognized RNAP. Our kinetic assays revealed...
The mechanism of TiO2 nanotubes has attracted increasing attention. However, relationships between the anodizing parameters and nanotube size (or oxide volume) have been rarely studied. traditional field-assisted dissolution theory can only qualitatively explain cause pore formation but cannot quantitatively relationship growth height current. Here, growing processes in four current at three different NH4F concentrations were carefully Experimental results contradicting found. Considering...
An inexpensive procedure to fabricate highly ordered , patterned through‐hole nanopore arrays of anodic aluminum oxide (AAO, see Figure) with intermittent supports has been developed. Silica was used as the anodization barrier. Using a two‐step process, straight nanopores AAO are formed in unpatterned areas; no pores found areas.
Nanoporous tin oxide layers were fabricated in NaOH during potentiostatic anodization at a low potential. With increasing potential, the nanochannel became fragmentized and stacked morphology was formed. The total anodizing current separated into ionic electronic to explain various morphologies of nanotubes. determines ion migration growth. oxygen evolution, porous structure formation, volume expansion. continuous decline current–time curve 8 V explained by capacitor model. Through cyclic...
Abstract Background Oral submucous fibrosis (OSF) is a precancerous lesion characterized by fibrous tissue deposition, and the incidence positively correlated with degree of betel nut chewing. Prolonged chewing can damage integrity oral mucosal epithelium, leading to chronic inflammation local immunological derangement, while underlying cellular events driving fibrogenesis dysfunction are incompletely understood. Currently, OSF has few treatment options, limited therapeutic effectiveness....
Porous anodic Sn oxide (PASO) and other porous oxides have aroused worldwide scientific interest. However, the relationship between complex structure current-time curve cannot be interpreted by traditional dissolution theory. In particular, with change of anodizing conditions Sn, sometimes shows three stages, five stages. order to study growth model PASO during anodization, this compares processes Ti. Under normal circumstances, Ti in process is which can reasonably electronic current oxygen...
