[Ab] Resumo:There has been active interest to identify new methods to reduce CO into usable fuel sources. In this work, we demonstrate two types of photo-electrochemical cells (PECs) that photoreduce CO directly to formate in aqueous solutions both in the presence and absence of external bias or additional electron sources. The photocathodes were either a CuFeO /CuO electrode or a bilayer of CdTe on NiO, whereas the photoanode was a bilayer of NiO on CdS. The PECs were characterized by using both electrochemistry and spectroscopy, and the products formed from CO reduction were characterized and quantified by using H NMR spectroscopy and ESI-MS. In addition, an organohydride catalyst was tested in conjunction with the PECs, which not only showed a significant gain of 85 times in CO reduction (27 µm formate without the catalyst, 2.3 mm formate with it) compared to the NiO/CdTe photocathode system but could also generate methanol under an external bias (10 µm).

[Ti] Título:Effect of Formamidinium/Cesium Substitution and PbI on the Long-Term Stability of Triple-Cation Perovskites.

[Ab] Resumo:Altering cation and anion ratios in perovskites has proven an excellent means of tuning the perovskite properties and enhancing the performance. Recently, methylammonium/formamidinium/cesium triple-cation mixed-halide perovskites have demonstrated efficiencies up to 22 %. Similar to the widely explored methylammonium lead halide, excess PbI is added to these perovskite films to enhance their performances. The excess PbI is known to be beneficial for the performance. However, its impact on stability is less well known. Triple-cation perovskites deploy excess PbI up to 8 %. Thus, it is imperative to analyze the role of excess PbI in the degradation kinetics. In this study, the amount of PbI in the triple-cation perovskite films is varied and the degradation kinetics monitored by X-ray diffraction and optical absorption spectroscopy. The inclusion of excess PbI is shown to adversely affect the stability of the material. Faster degradation kinetics are observed for samples with higher PbI contents. However, samples with excess PbI also showed superior properties such as enhanced grain sizes and better optical absorption. Thus, careful management of the PbI quantity is required to obtain better stability and alternative pathways should be explored to achieve better device performance rather than adding excess PbI .

[Ab] Resumo:The Magnetite Fe O quantum dots anchored SnO nanofibers (Fe O QDs/SnO NFs) have been synthesized using the facile one step hydrothermal method. The characteristic structure of synthesized Fe O QDs/SnO NFs was analyzed using X-ray diffraction, Transmission electron Microscopy, Scanning electron microscopy, UV-vis diffuse reflectance, photoluminescence spectroscopy, and N adsorption-desorption instrumental techniques. The crystallites size of Fe O QDs/SnO NFs was 7.0nm. The average diameters of Fe O QDs/SnO NFs were 7.25nm. BET surface area of Fe O QDs/SnO NFs has been found 53.064m /g. The activity of Fe O QDs/SnO NFs samples were compared towards adsorption and degradation of mutagenic compound such as Ethyl methanesulfonate (EMS). The Fe O QDs/SnO NFs demonstrates 93.85% and 56.85% photo degradation and adsorption activity towards 10ppm EMS solution in 30 and 40min, respectively. Fe O QDs/SnO NFs shows maximum removal of EMS at pH5. Additionally, cytotoxicity test showed that the newly developed catalyst has low cytotoxic effects on three kinds of human cells. The antibacterial activity evaluation against two bacterials, including Staphylococcus aureus (ATCC 43300), and Pseudomonas aeruginosa (ATCC 27853) was considered. It was found that the MIC values for the antibacterial assay in the presence of Fe O QDs/SnO NFs were around 0.38mM with 83.4, and 85.5% inhibition for the S. aureus, and P. aeruginosa bacterial strains, respectively.

[Ab] Resumo:The progress of the enriched photocatalytic degradation predominantly depends on materials fabrication. In the recent times, the outcomes of nanomaterials show extraordinary efficiency due to its shape and size. In this connection, the present work concentrates on the fabrication of single digit metal oxides (CeO , CuO, NiO, Mn O , SnO and ZnO) through precipitation method. The structural information of different metal oxides (MOs) and their crystallite size were estimated via XRD analysis and their consistent results revealed that the crystalline sizes of the prepared metal oxide were exhibited in nano size. The morphology and dimension of the synthesized MOs were identified through FE-SEM and TEM techniques. The FE-SEM images were apparently defined that the actual morphology of each metal oxide expresses different dimension due to nucleation and growth process. The result of UV-vis absorption spectra was helped to identify the band gap of MOs and a suitable light for photocatalytic irradiation. Additionally, the synthesized single digit MOs nanoparticles were magnificently applied for the degradation of methyl orange and methylene blue under UV light irradiation.

[Ti] Título:Comparison of the toxicity of sintered and unsintered indium-tin oxide particles in murine macrophage and epidermal cells.

[Ab] Resumo:Indium-tin oxide (ITO) is used to produce flat panel displays and several other technology products. Composed of 90% indium oxide (In O ) and 10% tin oxide (SnO ) by weight, ITO is synthesized under conditions of high heat via a process known as sintering. Indium lung disease, a recently recognized occupational illness, is characterized by pulmonary alveolar proteinosis, fibrosis, and emphysema. Murine macrophage (RAW 264.7) and epidermal (JB6) cells stably transfected with AP-1 to study tumor promoting potential, were used to differentiate between the toxicological profiles of sintered ITO (SITO) and unsintered mixture (UITO). We hypothesized that sintering would play a key role in free radical generation and cytotoxicity. Exposure of cells to both UITO and SITO caused a time and dose dependent decrease of the viability of cells. Intracellular ROS generation was inversely related to the dose of both UITO and SITO, a direct reflection of the decreased number of viable RAW 264.7 and JB6/AP-1 cells observed at higher concentrations. Electron spin resonance showed significantly increased hydroxyl radical (OH) generation in cells exposed to UITO compared to SITO. This is different from LDH release, which showed that SITO caused significantly increased damage to the cell membrane compared to UITO. Lastly, the JB6/AP-1 cell line did not show activation of the AP-1 pathway. Our results highlight both the differences in the mechanisms of cytotoxicity and the consistent adverse effects associated with UITO and SITO exposure.

[Ab] Resumo:Bulk-type all-solid-state lithium-ion batteries (ASLBs) for large-scale energy-storage applications have emerged as a promising alternative to conventional lithium-ion batteries (LIBs) owing to their superior safety. However, the electrochemical performance of bulk-type ASLBs is critically limited by the low ionic conductivity of solid electrolytes (SEs) and poor ionic contact between the active materials and SEs. Herein, highly conductive (0.14 mS cm ) and dry-air-stable SEs (Li SnS ) are reported, which are prepared using a scalable aqueous-solution process. An active material (LiCoO ) coated by solidified Li SnS from aqueous solutions results in a significant improvement in the electrochemical performance of ASLBs. Side-effects of the exposure of LiCoO to aqueous solutions are minimized by using predissolved Li SnS solution.

[Ab] Resumo:To create facile external controlled drug delivery system, a magnetic porous carrier based on Tin oxide nanoparticles was synthesized by an inexpensive and versatile hydrothermal strategy and used for in-vitro process. Magnetic nanocomposites were qualified by Fourier Transform Infrared (FTIR), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), Vibrational Sample Magnetometer (VSM) and Transmission Electron Microscopy (TEM). Results showed that nanoparticles were synthesized successfully with good dispersion of magnetic nanoparticles in cavity, uniform particle size distribution with average size of 65nm and high magnetization of 33.75 emu/mg. Furthermore, the nano-porosity and magnetism allowed high efficiency and remote controlled drug release. In this study, anti-migraine Sumatriptan was used as drug sample and the effect of drug concentration, Fe/Sn ratio and loading time on drug absorption were investigated. The best result was checked for stability at body temperature and different body pH. The sample with drug concentration of 0.25(mg/ml), Fe/Sn=0.22 and loading time of 1.5h had the highest drug efficiency (70%). Finally, in order to simulate the in vivo process for in-vitro step, Amnion was used and drug diffusion rate was measured in different intervals and different pH values. The result illustrated that after 25h, diffusion reached 65% at pH=2 and 56% at pH=7, and then became constant. Based on the above mentioned results, the carrier has an acceptable in vitro yield and therefore could be chosen for future in vivo researches.

[La] Idioma:eng
[Ab] Resumo:A potentiometric enzyme biosensor is a convenient detector for quantification of urea concentrations in industrial processes, or for monitoring patients with diabetes, kidney damage or liver malfunction. In this work, poly(3-hexylthiophene- -3-thiopheneacetic acid) (P(3HT- -3TAA)) was chemically synthesized, characterized and spin-coated onto conductive indium tin oxide (ITO) glass electrodes. Urease (Urs) was covalently attached to the smooth surface of this copolymer via carbodiimide coupling. The electrochemical behavior and stability of the modified Urs/P(3HT- -3TAA)/ITO glass electrode were investigated by cyclic voltammetry, and the bound enzyme activity was confirmed by spectrophotometry. Potentiometric response studies indicated that this electrode could determine the concentration of urea in aqueous solutions, with a quasi-Nernstian response up to about 5 mM. No attempt was made to optimize the response speed; full equilibration occurred after 10 min, but the half-time for response was typically <1 min.

[Ti] Título:AC dielectrophoretic manipulation and electroporation of vaccinia virus using carbon nanoelectrode arrays.

[Ab] Resumo:This paper reports the capture and detection of vaccinia virus particles based on AC dielectrophoresis (DEP) and electrochemical impedance measurements employing an embedded vertically aligned carbon nanofiber (VACNF) nanoelectrode array (NEA) versus a macroscopic indium-tin-oxide (ITO) transparent electrode in a "points-and-lid" configuration. The nano-DEP device was fabricated by bonding two SU-8 covered electrodes patterned using photolithography. The bottom electrode contains a 200 × 200 µm active region on a randomly distributed NEA and the top electrode contains a microfluidic channel in SU-8 spin-coated on ITO to guide the flow of the virus solution. The real-time impedance change was measured during DEP capture and validated with fluorescence microscopy measurements. The NEA was able to capture virus particles with a rather low AC voltage (∼8.0 V peak-to-peak) at 1.0 kHz frequency as the particles were passed through the fluidic channel at high flow velocities (up to 8.0 mm/s). A concentration detection limit as low as ∼2.58 × 10 particles/mL was obtained via impedance measurements after only 54 sec of DEP capture. At the low AC frequencies (50.0 Hz or less), the high electric field at the exposed VACNF tips induced electroporation of the DEP-captured virus particles, which was validated by fluorescence emission from the dyes staining lipophilic membrane and internal nucleic acid, respectively. This study suggests the possibility of integration of a fully functional electronic device for rapid, reversible and label-free capture and detection of pathogenic viruses, with a potential of generating electroporation to the captured the virus particles for further biochemical study.

[Ab] Resumo:A 74-year-old woman with liver cirrhosis and chronic kidney disease (CKD) who had complained of chronic abdominal distension due to prominent ascites presented with sudden dyspnea. Chest radiography showed massive right pleural effusion that shifted the mediastinum. Peritoneal scintigraphy using 99mTc-macroaggregated albumin revealed pleuroperitoneal communication (PPC). As her hydrothorax was refractory and frequent thoracentesis did not improve her respiratory distress, thoracoscopic surgery was performed for repair of the diaphragm defect. Continuous ambulatory peritoneal dialysis (CAPD) was started soon after surgery because her renal function was progressively worsening, and there was no recurrence of hydrothorax. The chronic abdominal distension resolved as her ascites decreased. In addition, peritoneal protein loss decreased after initiation of peritoneal dialysis (PD). PPC is an uncommon but serious complication of PD, and PD patients with PPC are often forced to discontinue PD. To our knowledge, no report has presented successful PD induction in a patient with evident PPC. We believe that further accumulation of such cases will expand the treatment options for CKD.
