- Khaled Hussein added an answer:Has any one come across phosphomolybdate incorporated mesoporous materials?
I am looking for technique where ammonium phosphomolybdate can be incorporated into the framework of some mesoporous / microporous materials (preferably silica)? I tried looking for MCM-41 type of material however these kind of material can only be synthesized in alkaline (pH 9-11) and in that condition Phosphomolybdate precursor will dissolve.
I am not particularly looking for impregnates techniques due to its leaching problem.
Try to use autoclave at 120 ًَُُ c for 6hrs .....
keep MCM-41 synthesis conditions the same and try ...

why do we use from the Mie scattering regime in metal nanoparticles and not Rayleigh scattering regime ?
Expanding slightly Eric's answer, I'd add that a range of sizes of metal nanoparticles can be very broad, from few nm to hundreds of nm indicating that the condition of using the Rayleigh approach is not valid.Following

I want to know novel active agents in a food packaging.
Silver is not very reactive with oxygen, unlike reducing metals like alkaline or alkaline earth metals. Silver reacts with sulphur instead, hence the black colour of old silver.

- Biswajit Bose added an answer:I got a peak at 422/423 nm in UV spectra. What is the size of my Ag nanoparticle?Does colour and size of silver nanoparticles depend on each other? I used to get a peak at 430-450nm in UV spectra, but now I am getting a peak at 423nm. Sometimes I get double peaks (one small @ 423 and other @ 436 nm). What is the reason for this?

- Titus Sobisch added an answer:What are Nano-Surfactants?I was wondering if anyone could help me gain information about nano-surfactants, their types and structure and their used in enhanced oil recovery.Just because a material can be used for same purpose it does not mean it belongs to the same specific group of materials.
E.g. emulsions can be stabilized by particles, polymers and surfactants, i.e. all can be called emulsifiers. Nevertheless, for clarity one has to distinct them based on specific properties. E.g. surfactants compounds with pronounced reduction of interfacial tension at relatively low concentration. Oil can be removed by commercial oil binders, which should not be confused with washing agents removing oil stains, oil films etc.Following

- Periklis Papadopoulos added an answer:Which organosilanes are used to make glass surface super-hydrophobic/ super-hydrophilic?Can anyone please help me to select a proper organosilane combination or titanates with inorganic nanoparticles which will form thin film (monomolecular) on glass surface in short time span and at room temperature. It is important that there is no effect on its optical transparency and that it cures at room temperature.Superhydrophilic is quite easy, just treat the glass with O2 plasma. However, you cannot make a surface "super"hydrophobic just by coating with an organosilane, you need to create a texture like the lotus leaf. To hydrophobize you can use either alkyl-chlorosilanes (better trichlorosilanes) or perfluoroalkyl-trichlorosilanes.Following

- Gabriele Penazzi added an answer:Need assistance with references to experimental or theoretical work on the geometry of InAs/InP interface.Hello everybody!
I'm currently trying to model a heterostructure nanowire. In order to study the IV characteristics using DFT-NEGF formalism, I need to build my device using realistic geometric parameters. The parameters for each crystal separately are well known, but I've been trying to find a geometric description of the interface InAs/InP. Can anyone help me with some references to experimental or theoretical work done on the subject? Thank you!Hi Sebastian,
I'm assuming that both the crystal have the same phase (fcc). The lattice mismatch between InAs and InP is not that big, probably the assumption of pseudomorphic growth is save. You find the basic theory of pseudomorphic growth in many solid state physics or device physics textbooks (for example, Cardona, fundamentals of semiconductors). You can relax the structure with any reliable method which takes into account internal strain: classical force field, dft etc. The main point is that, give InAs as a substrate, you fix the starting InP lattice such that it matches with InAs at surface. Be aware that dft here can be pretty heavy, as usually you need to calculate quite a large cell to ensure strain relaxation at the boundary.
There's plenty of literature about classical force field, continuum models and so on.
You can search for the works from D. Bimberg, G. Klimeck, A. Zunger, Y.M. Niquet (and many relevant others who I am not mentioning).Following
- Titus Sobisch added an answer:Self Assembling Nano Inhibitors?Does anyone know where I can find information on how to stop or put a damper on the self assembly process? Is the process 100% dependent on the nano components and how they were fabricated, or is there some general knowledge associated with the self assembly process? I'm assuming that it is all frequency based, but that's an assumption. I am new to this technology, so any links or info would be helpful.
