Bismuth oxide may be a promising battery material due to the high gravimetric (690 mAh g(-1)) and volumetric capacities (6280 mAh cm(-3)). However, this intrinsic merit has been compromised by insufficient Li-storage performance due to poor conductivity and structural integrity. Herein, we engineer a heterostructure composed of bismuth oxide (Bi2O3) and bismuth sulphide (Bi2S3) through sulfuriz...

Quantum-confined Bi structures (quantum wells and quantum wires) are currently being studied for their varies novel properties. We now pursue the next level of quantum confinement in bismuth, quantum dots. In this work, we present a technique for the synthesis of bismuth nanoparticles using an inverse microemulsion method. To prevent air-oxidation in the characterization stage, poly(vinylpyrrol...

Saturable absorption in bismuth-doped glasses was found to have a noticeable influence on soliton interaction and group formation. This phenomenon, observed in 1450 nm mode-locked bismuth-doped fiber laser, shows the distinct feature of the multiple pulse regime, which appears as a stationary pulse group whose length can be spread over the whole cavity length by variation of the pump power and ...

Recent advances in high-pressure techniques offer chemists access to vast regions of uncharted synthetic phase space, expanding our experimental reach to pressures comparable to the core of the Earth. These newfound capabilities enable us to revisit simple binary systems in search of compounds that for decades have remained elusive. The most tantalizing of these targets are systems in which the...

Introduction In the past, thin uranium fluoride targets in the form of UF4 on carbon backings were applied for heavy-ion experiments repeatedly. With this compound targets we had several problems: UF4 had to be evaporated on thick carbon substrates of about 45 μg/cm2. The targets were mechanically very fragile and showed heavy sputtering in the beam. The durability of the targets upon irradiati...

In this study, the photocatalytic degradation of azo-dye acid orange 10 was investigated using titanium dioxide catalyst suspension, irradiation with ultraviolet-C lamp and bismuth vanadate under visible light of light-emitting diode lamp. Response surface methodology was successfully employed to optimize the treatment of acid orange 10 dye and assess the interactive terms of four factors. The ...

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)...
