Here, a lead-free silver bismuth iodide (AgI/BiI3 ) with a crystal structure with space group R3‾ m is investigated for use in solar cells. Devices based on the silver bismuth iodide deposited from solution on top of TiO2 and the conducting polymer poly(3-hexylthiophene-2,5-diyl) (P3HT) as a hole-transport layer are prepared and the photovoltaic performance is very promising with a power conver...
This project studies the synthesis process of 2-D nanostructure of Bismuth oxycholride(BiOCl). The experiment involves synthesis of BiOCl particles and its exfoliation steps. BiOCl will be synthesized from Bismuth Nitrate (Bi(NO3)3) or Bismuth Cholride(BiCl3) with water, and Hydrochloric acid(HCl). Synthesized particles will be dispersed in Methyl Amine-Methanol solution and subjected to sonica...
A 76-year old white married female had rapid onset dementia with myoclonus and was admitted to an HMO hospital where she was initially diagnosed as Alzheimer's disease. The physician- husband suggested that the condition might be due to the Pepto-Bismol which she had taken chronically to control her irritable bowel syndrome. An elevated serum bismuth level of 242 &mgr;g/L (normal is 5 &mgr;g/L)...
Mercury substitution is a big issue in electroanalysis, and the search for a suitable, and less toxic, replacement is still under development. Of all the proposed alternatives, bismuth films appear to be the most viable solution, although they are still suffering some drawbacks, particularly the influence of deposition conditions and linearity at low concentrations. In this paper, the most prom...
Significantly enhanced superbroadband near infrared emission has been realized in bismuth/aluminum doped high-silica zeolite derived nanoparticles. The emission intensity can be easily tailored by the introduction of aluminum. The luminescence lifetime can reach up to 695 micros. The results reveal that the existence of charge imbalance environment caused by [AlOV(4/2)](-) units in host materia...
The problems of the development of high-temperature radiation resistant ultrasonic sensors operating in a liquid lead-bismuth alloy are analysed. Experimental diffusion bonded bismuth titanate sensors for operation up to 450 °C were developed. For acoustical coupling with a liquid metal the sensor protector is polished or coated by a diamond like carbon layer. The developed sensors survived hig...
The properties of nanosized bismuth particles are investigated using a nanocalorimetric technique. A brief description of the experimental method and data analysis procedures is reported. Bismuth nanoparticles are found to melt at a temperature below that of bulk material, but higher than expected using the standard model. Also included is the results of a finite element analysis and simulated ...
A supramolecular porphyrin nanotube displaying J-aggregation feature was constructed by out-of-plane coordinated bismuth-porphyrin. Significantly, compared to traditional J-aggregated porphyrin suffering from fluorescence and singlet oxygen quenching, the nanotube exhibits excellent bio-imaging ability and enhanced production efficiency of singlet oxygen. The out-of-plane structure of bismuth t...
Sir,?With reference to my paper 'Treatment of Amoebic Dysentery with E.B.I. Retention Enemas published in the Indian Medical Gazette of August 1947, I should like to add that in the meantime I have treated a number of additional cases -without the addition of bismuth-iodide to the retention enemas. The results have been as good as those obtained with the enemas not containing bismuth-iodide. Th...
