Graphene has attracted extensive research interest due to its strictly 2-dimensional (2D) structure, which results in unique electronic, thermal, mechanical, and chemical properties potential technical applications. These remarkable characteristics of graphene, along with the inherent benefits a carbon material, make it promising candidate for application electrochemical energy devices. This article reviews methods graphene preparation, introduces behavior summarizes recent development on...

Ion motion in a Penning trap and the electrical signals it can produce have been analyzed for purpose of identifying important causes uncertainty high-accuracy mass measurements heavy ions. The role azimuthal quadrupole electric field signal pickup, its effects on ion at sum frequency cyclotron magnetron motions, identified. A useful scheme calculating strength interaction between an applied has developed. sources using motions determining are discussed. Particular application is made to...
Permeabilized intestinal absorptive cell brush borders contain a perijunctional ring of actin and myosin (PAMR) that can be induced to contract. Recently, morphological changes suggestive PAMR contraction were shown occur in cells ileal epithelium after exposure cytochalasin D (CD) (J. Cell Biol. 102: 2125-2136, 1986). With this response, altered tight junction structure enhanced permeability also occur. To further assess the relationship between permeability, we examined effect uncoupler...
The study presented here is a fundamental investigation into the molecular origins of thermal transitions and dynamic mechanical relaxations Nafion membranes as studied by DSC, DMA, variable temperature small-angle X-ray scattering (SAXS), solid-state 19F NMR spectroscopy. While several studies in literature have attempted to explain these relaxations, assignments were based primarily on limited DMA results at times been contradictory. In DSC traces Nafion, low- high-temperature endotherms...

Abstract Soybean ( Glycine max L. ev. Columbus) seedlings grown in culture solution were treated with cadmium as CdSO 4 . Final concentrations of (Cd 2+ ) the 0, 0.45, 0.90, and 1.35 μ M. leaves, analyzed 10 days after Cd was added to solution, showed increased respiration rate activities malate dehydrogenase, acid phosphatase, ribonuclease, deoxyribonuclease, peroxidase but decreased activity carbonic anhydrase. Increased hydrolytic enzymes reflects a general senescence response while...
Novel acrylic monomers functionalized with nucleobase-containing units (adenine and thymine) were prepared upon aza-Michael addition successfully copolymerized n-butyl acrylate. At a content of 7 mol %, adenine-containing self-assembled into needle-like microstructures within amorphous polymer matrices as shown atomic force microscopy (AFM), small-angle X-ray scattering (SAXS), wide-angle diffraction (WAXD); thymine-containing did not aggregate distinct morphologies even to 30 %. Upon...
Although many different structural models have been proposed for perfluorosulfonic acid (PFSA) ionomers such as Nafion, the very high degree of disorder in these materials makes it difficult, if not impossible, to deduce their morphology unambiguously from small angle X-ray and neutron scattering (SAXS/SANS) experiments alone. We present a combination model-independent procedure obtaining information SAXS patterns based on Maximum Entropy (MaxEnt) approach coupled with mesoscale simulations...

We investigated moisture and thermal stability of MAPbBr3 perovskite material. Cubic was found to be moisture-insensitive can avoid the issues introduced by low-temperature phase transition in MAPbI3. MAPbI3 hybrid solar cells with efficiencies ∼7.1% ∼15.5%, respectively, were fabricated, we identified correlation between working temperature, light intensity, photovoltaic performance. No charge-carrier transport barriers cells. The cell displays a better under high temperature because its...
A structural study using both small-angle X-ray and neutron scattering (SAXS SANS) of dry water-swollen short pendant side chain perfluorosulfonated ionomer (SPC PFSI) membranes is presented. The SAXS SANS profiles are shown to be equivalent, confirming the phase separation between water perfluorinated matrix. asymptotic behavior at large angles curves confirms that structure dominated by polymer−solvent interfacial energy. local order model satisfactorily reproduce obtained for SPC PFSI...
