For the cells in the experiment, we got some trout gill cells (trout is a freshwater fish species used for research a lot), the idea being that in the real world fish might take up nanoparticles through their gills. We broke open the cells, and put all the cell innards (technically ca...
What is LSPR and how is it different from traditional SPR? Traditional SPR uses a continuous gold film, while LSPR is created through metal nanoparticles, usually silver and gold. A powerful resonance absorbance peak is produced in the visible range of light by LSPR. What is surface plasmon wa...
aThe reason advanced for the adverse effect of low pH on the photocatalyst performance is that the possible increase of H+ concentration may restrain hydrolyzation of Ti(OBu)4 and thereby reduces the crystal size of the prepared N-doped TiO2 nanoparticles. 为不利影响提出的原因的低酸度值在...
What is meant by 'doping' in a semiconductor? What is the role of graphite in the electrometallurgy of aluminium? Why can the same types of reagents produce colloidal silver under one set of conditions, then silver nanoparticles under another set of conditions? Explain the differences in ...
by Brazil delegate that walked through long list of research papers in past years. There was strong interest in few presentations – one by IITB about nanoparticles presence in homeo medicines, few on nosodes, one about application to cancer and one more that I mention little later. I might ...
What is the major assumption underlying the metal-ligand interactions in crystal field theory? What are the main factors that affect the magnitude of the crystal field splitting? What is meant by the spectrochemical series? What are superacids? How are these formed and how do they work ?
"Every time we create nanoparticles from the other precursors Pu(III), (IV) or (V) the reaction is very quick, but here we observed a weird phenomenon half way," Kristina Kvashnina, a physicist from HZDR, says in a press statement. When the scientists were looking over their creation...
We’re going to get back to using nanoparticles to deliver their blimp full of drug soccer balls in a second. But first, let’s go back to what Ainissa said about nano, which is that it’s not just small; it’s also strange. ...
During the development of a delivery system for skin application, it is crucial to perform ex vivo permeation tests meant to evaluate drug permeation across the skin layers. Guidelines for standard experimental protocols for skin permeation studies were defined by the Organization for Economic Cooperatio...
Is silicon a conductor or semiconductor? Explain. What are the differences between semiconductor and metal nanoparticles? Is gold a conductor or a semiconductor? Explain. Is silver a conductor or a semiconductor? Explain. Use the band model to describe differences among insulator...
