Transmission electron microscopy (TEM) microstructural characterization and microchemical analysis are two tools which can help relate proton exchange membrane (PEM) processing resulting structure to fuel cell performance as well structural changes loss. A necessary first step is the preparation of specimens suitable for TEM that maintain spatial relationships among various macro- microcomponents an entire PEM cell. By carefully keeping intact during sample preparation, valuable information...
Consequences of heat stress exposure during the first 12 h meiotic maturation differed depending on how and when bovine oocytes were activated. If heat-stressed underwent IVF at ~24 h, blastocyst development was less than for respective controls similar to that obtained nonheat-stressed undergoing 30 (i.e. slightly aged). In contrast, if chemical activation with ionomycin/6-dimethylaminopurine 24 not only higher controls, but also equivalent after h. Developmental differences in chemically...
Life cycle assessments (LCAs) were performed for per- and polyfluoroalkyl substance (PFAS) treatment with ion exchange (IX) followed by electrochemical oxidation (EO). For the studied water quality, global warming potentials (GWPs) two orders of removal perfluorooctane sulfonic perfluorooctanoic acids from 1000 m3 samples 72.2 84.9 kg CO2 eq., respectively. The major contributors to GWP electricity resin manufacturing. To understand environmental impacts different options, following...
Aluminum, long known to be detrimental soybean productivity, was localized in the polyphosphate granules (PPG) of bacteroids root nodules plants. By using energy-dispersive X-ray analysis, early infections were shown have typical PPG constituents. However, older and after digested intracellularly, aluminum also detected. These results indicate that accumulates a period when organisms been resident host cells high levels present at time their demise. At least some these laboratory-grown...
Abstract Conventional energy analyses of forestry systems capture only human inputs and harvests, neglecting impacts to forest biomass stocks resulting from intensive management. This gap is addressed by extending the boundaries operations whole ecosystem. These new allow for quantification cumulative foregone ( ΔB c , difference between accumulated potential existing over time) under differing management scenarios supplement interpretation conventional metrics such as net NE ) ratio return...

Several studies have been undertaken to investigate the fine structure and superconductive properties of high temperature superconductors. Yuan et al. utilized electron energy loss spectroscopy (EELS) determine dielectric function superconductor Ba 2 YCu 3 O 7-x . In this study we performed EELS on Bi 1.8 Pb 0.3 Sr Ca Cu 10 at both room below transition calculated such as fuction, inelastic mean free path stopping power for material. Powdered was dispersed by sonication in a 0.2% (wt/v)...
