Barium sulphate has been used as a gastrointestinal (GI) contrast agent for over 100 years. Since the first report of single contrast barium radiography in 1910, barium techniques have evolved in parallel with technical developments such as fluoroscopic image intensification. Double contrast techniques were first described in the 1920s but did not become mainstream until the 1960s and 1970s whe...

Processes for recycling lithium ion batteries (LIB), in particular complex chemistries such as those containing nickel-manganese-cobalt oxide (NMC) cathodes are hindered by tradeoffs between capital cost, process sustainability, and materials recovery. Most metal separations primary secondary production of critical elements rely on anion exchange chemistries. Herein, we explore the application ...

Nanoparticles of barium carbonate/oxalate have been synthesized in situ from barium nitrate and ammonium carbonate/oxalate by reverse micelle method. These particles were characterized using transmission electron microscope (TEM), fourier transform infrared (FTIR) and x-ray diffraction (XRD). The results indicate that rod-like barium carbonate (BaCO3) and spherical barium oxalate (BaC2O4) nanop...

In this research thin film heterogeneous cation exchange membrane was prepared by interfacial polymerization of polyacrylic acid-co-iron nickel oxide nanoparticle son PVC based substrate. Spectra analysis confirmed graft polymerization conclusively. The SEM images showed that polymerized layer covers the membranes by simple gel network entanglement. Results exhibited that membrane water content...

On-chip electro-optic modulation is essential to realize complex on-chip optical signal processing. Recent developments in thin-film ferroelectric oxide for high-speed electro-optical modulators have gained considerable interest understanding and correlating the material property with response. Particularly, effect of thin film, domain orientation, polling on response not well understood. In th...
