3D Hepatic Cultures Simultaneously Maintain Primary Hepatocyte and Liver Sinusoidal Endothelial Cell Phenotypes
(PLOS, 2010-11-12)Developing in vitro engineered hepatic tissues that exhibit stable phenotype is a major challenge in the field of hepatic tissue engineering. However, the rapid dedifferentiation of hepatic parenchymal (hepatocytes) and ... -
Ambient ammonia synthesis via palladium-catalyzed electrohydrogenation of dinitrogen at low overpotential
(Springer Nature, 2018-05-15)Electrochemical reduction of N2 to NH3 provides an alternative to the Haber−Bosch process for sustainable, distributed production of NH3 when powered by renewable electricity. However, the development of such process has ... -
An atomic force microscope tip as a light source
(AIP Publishing, 2005-12-01)We present a simple method for causing the end of a silicon nitride atomic force microscope (AFM) tip to emit light, and we use this emitted light to perform scanning near-field optical microscopy. Illumination of a silicon ... -
Comparison Of Flow Birefringence Data with A Numerical-Simulation Of The Hole Pressure
(AIP Publishing, 1988-08-01)The penalty_Galerkin finite_element method is used to simulate the flow of a polystyrene melt over a rectangular slot placed perpendicular to the flow direction. The White_Metzner constitutive equation is used with a Carreau ... -
Comparison Of The Rheological Properties Of Concentrated-Solutions Of A Rodlike And A Flexible Chain Polyamide
(AIP Publishing, 1979)The steady state shear rheological properties of solutions of a rodlike polyamide, poly_p_phenyleneterephthalamide (PPT), in 100% sulfuric acid have been compared with those of solutions of a flexible chain polyamide, nylon ... -
Computational study of HIV gp120 as a target for polyanionic entry inhibitors: Exploiting the V3 loop region
(PLOS, 2018-01-18)Multiple approaches are being utilized to develop therapeutics to treat HIV infection. One approach is designed to inhibit entry of HIV into host cells, with a target being the viral envelope glycoprotein, gp120. Polyanionic ... -
A correlation force spectrometer for single molecule measurements under tensile load
(American Institute of Physics, 2013-01-07)The dynamical-mechanical properties of a small region of fluid can be measured using two closely spaced thermally stimulated micrometer-scale cantilevers. We call this technique correlation force spectroscopy (CFS). We ... -
Correlations between the thermal vibrations of two cantilevers: Validation of deterministic analysis via the fluctuation-dissipation theorem
(AIP Publishing, 2012-02-01)We validate a theoretical approach for analyzing correlations in the fluctuations of two cantilevers in terms of a deterministic model, using the fluctuation-dissipation theorem [M. R. Paul and M. C. Cross, Phys. Rev. Lett. ... -
Creation of a gradient polymer-fullerene interface in photovoltaic devices by thermally controlled interdiffusion
(AIP Publishing, 2002-12-01)Efficient polymer-fullerene photovoltaic devices require close proximity of the two materials to ensure photoexcited electron transfer from the semiconducting polymer to the fullerene acceptor. We describe studies in which ... -
Design Of A High-Temperature And High-Pressure Liquid Flow Cell For X-Ray Absorption Fine Structure Measurements Under Catalytic Reaction Conditions
(AIP Publishing, 2008-01-01)The design and performance of a new high-pressure and high-temperature cell for measurement of x-ray absorption fine structure (XAFS) spectra of solid catalysts working in a flowing liquid are presented. The cell has flat, ... -
Discovering Networks of Perturbed Biological Processes in Hepatocyte Cultures
(PLOS, 2011-01-05)The liver plays a vital role in glucose homeostasis, the synthesis of bile acids and the detoxification of foreign substances. Liver culture systems are widely used to test adverse effects of drugs and environmental ... -
Dynamic Mechanical And Thermal Behavior Of Novel Liquid-Crystalline Polybutadiene-Diols with Azobenzene Groups in Side Chains
(AIP Publishing, 2013-09-01)Liquid-crystalline (LC) polymers containing methoxy-or butoxy-substituted azobenzene in side chains have been prepared via radical addition of the in advance synthesized nematic thiols onto double bonds of poly(butadiene) ... -
Endothelial Cell Capture of Heparin-Binding Growth Factors under Flow
(PLOS, 2010-10)Circulation is an important delivery method for both natural and synthetic molecules, but microenvironment interactions, regulated by endothelial cells and critical to the molecule's fate, are difficult to interpret using ... -
An Evaluation Of The Doi-Ohta Theory For an Immiscible Polymer Blend
(AIP Publishing, 1996-01-01)The theory developed by Doi and Ohta was evaluated for its ability to predict the rheology of an immiscible polymer blend. The theory describes the additional stresses arising as a consequence of interfacial tension in two ... -
Femtosecond Laser Pulse Driven Melting in Gold Nanorod Aqueous Colloidal Suspension: Identification of a Transition from Stretched to Exponential Kinetics
(Nature, 2015-01-30)Many potential industrial, medical, and environmental applications of metal nanorods rely on the physics and resultant kinetics and dynamics of the interaction of these particles with light. We report a surprising kinetics ... -
Focusing of mammalian cells under an ultrahigh pH gradient created by unidirectional electropulsation in a confined microchamber
(The Royal Society of Chemistry, 2014-06-09)The transport and manipulation of cells in microfluidic structures are often critically required in cellular analysis. Cells typically make consistent movement in a dc electric field in a single direction, due to their ... -
Forces between Hydrophobic Solids in Concentrated Aqueous Salt Solution
(American Physical Society, 2012-03-05)Much research has focused on the discovery and description of long-ranged forces between hydrophobic solids immersed in water. Here we show that the force between high contact-angle solids in concentrated salt solution (1 ... -
Gas flow near a smooth plate
(American Physical Society, 2011-05-31)We examine gas flow adjacent to a molecularly smooth, solid, muscovite mica. The fluctuations in force acting on a glass sphere as a function of proximity to a mica plate were measured in air and were used to obtain the ... -
