The relative lung bioavailability of salbutamol sulfate particles produced using supercritical fluids (SEDS™) and delivered by dry powder inhaler (DPI) was compared with the performance of a conventional micronized drug DPI using the same device design (Clickhaler™, Innovata Biomed). Twelve healthy volunteers and 11 mild asthmatic patients completed(More)
Conventional graphitic anodes in lithium-ion batteries cannot provide high-power densities due to slow diffusivity of lithium ions in the bulk electrode material. Here we report photoflash and laser-reduced free-standing graphene paper as high-rate capable anodes for lithium-ion batteries. Photothermal reduction of graphene oxide yields an expanded(More)
Lithium metal is known to possess a very high theoretical capacity of 3,842 mAh g(-1) in lithium batteries. However, the use of metallic lithium leads to extensive dendritic growth that poses serious safety hazards. Hence, lithium metal has long been replaced by layered lithium metal oxide and phospho-olivine cathodes that offer safer performance over(More)
In this study, we report a novel route via microwave irradiation to synthesize a bio-inspired hierarchical graphene--nanotube--iron three-dimensional nanostructure as an anode material in lithium-ion batteries. The nanostructure comprises vertically aligned carbon nanotubes grown directly on graphene sheets along with shorter branches of carbon nanotubes(More)
Previous studies of the interaction of water with graphene-coated surfaces have been limited to flat (smooth) surfaces. Here we created a rough surface by nanopatterning and then draped the surface with a single-layer graphene sheet. We found that the ultrasheer graphene drape prevents the penetration of water into the textured surface thereby drastically(More)
Prevention of microbially induced corrosion (MIC) is of great significance in many environmental applications. Here, we report the use of an ultra-thin, graphene skin (Gr) as a superior anti-MIC coating over two commercial polymeric coatings, Parylene-C (PA) and Polyurethane (PU). We find that Nickel (Ni) dissolution in a corrosion cell with Gr-coated Ni is(More)
a r t i c l e i n f o JEL Classification: F21 G01 G34 Keywords: Fire sales Foreign direct investment Cross-border mergers and acquisitions Financial crises Flipping Motivated by a set of stylized facts, we develop a model of cross-border mergers and acquisitions (M&As) to study foreign direct investment (FDI) in emerging markets. We compare acquisitions(More)
PURPOSE To evaluate the precision of using digitally reconstructed radiographs (DRRs) of either 3 mm or 6 mm slice separation vs. using simulator images for the setup verification of patients receiving CT planned conformal radiotherapy to the prostate. To calculate the transfer error between CT and simulator. METHODS AND MATERIALS Twenty patients were CT(More)
Equity home bias is one of the most enduring puzzles in international finance. In this paper, I start out by documenting a novel stylized fact about home bias: countries with weaker domestic institutions hold fewer foreign assets. I then explore a macroeconomic mechanism by which the presence of agency problems in firms may explain this pattern. To do so, I(More)
