Attempts were made to improve fixation and embedding methods for electron microscopy of Alternaria alternata spores. Among 16 methods tested, the ultrastructural images were greatly improved by the use of an en bloc alkaline bismuth stain or an osmium tetroxide-potassium ferrocyanide (reduced osmium) fixative. The cellular membranes were highly contrasted even in unstained sections obtained fro...

Metal oxide varistors (MOVs) are a type of resistor with significantly nonlinear current-voltage characteristics commonly used in power lines to protect against overvoltages. If a proper recycling plan is developed MOVs can be an excellent source of secondary zinc because they contain over 90 weight percent zinc oxide. The oxides of antimony, bismuth, and to a lesser degree cobalt, manganese, a...

BACKGROUND Coronary computed tomographic angiography (CCTA) is associated with high radiation dose to the female breasts. Bismuth breast shielding offers the potential to significantly reduce dose to the breasts and nearby organs, but the magnitude of this reduction and its impact on image quality and radiation dose have not been evaluated. METHODS Radiation doses from CCTA to critical organs...

Flexible thermoelectric generators (f-TEGs), fabricated by the screen printing technique, have been introduced as a semi-permanent power source for wearable and flexible electronic systems. However, the output power density of the f-TEG module is still limited due to the low ZT of the screen-printed thermoelectric (TE) film. We herein report a post ionized defect engineering process that effect...

Despite the topical action of colloidal bismuth subcitrate in promoting the healing of peptic ulcers, slight absorption of bismuth from the gastrointestinal tract has been reported in colloidal bismuth subcitrate-treated animals and man. The uptake and subcellular distribution of bismuth by the gastrointestinal tract of rats after 24 hours of colloidal bismuth subcitrate administration was stud...

Current industrial silicon heterojunction (SHJ) modules use scarce materials such as silver for screen-printed contacts, indium indium-tin-oxide (ITO) transparent conductive oxide (TCO) layers, and bismuth Sn-Bi coated Cu wires low-temperature interconnection. SHJ solar cells more than double the (30.3 mg/W) mainstream passivated-emitter rear cell (PERC) technology. However, most pressing issue...

Bismuth oxide (Bi2O3) nanorods was prepared via one pot sol-gel method using Bi(NO3)3.5H2O and starch (as template) in water under hydrothermal condition followed by calcination at 320˚C within 3 h. The resultant solid product was characterized by scanning electron microscope (SEM), X-ray diffraction (XRD), thermogravimetry (TGA), and FTIR techniques. Based on the obtained results, the formatio...
