- Per Arvid Löthman added an answer:Nano-bubbles are claimed to have vast applications. How feasible is to produce nano-bubbles? and What improvements may be achieved?
Nano-bubbles are claimed to have applications in fishery, water treatments, medical applications and so on. The question is how feasible is to produce nano-bubbles because it may need very high pressure devices. And, what performance improvements is expected compared with smaller micro or mili bubbles?
Microwaves etc. can be used for nanobubble production. Now how stable they are in the long term?? Does anyone have experience or information about how to make nanobubbles with different methods as well as measurement of long time stability + characterization. I also heard that measuring the size of the nanobubbles is tricky since the bubbles may not be bubbles but simply nanoparticles form the equipment.
Nevertheless, some Japaneese companies make nanobubble equipment,Following

- Nanhao Zhang added an answer:Are there any other researchers doing experiments about vapor generation using nanoparticles?
Turning liquid into vapor directly is one of the new areas in nanoparticle application. It significantly improves efficiency by cutting the mediating process of heating the bulk water at first.
As far as I know, there are 3 teams carrying out such experiments, including Naomi J. Halas, P. E. Phelan, Ghasemi and their collaborators, respectively. What I wonder is that, except for all teams mentioned above, are there any other researchers doing such work.
I'm extremely curious about this topic and want to get some literature to learn.
Hope anyone in this field would provide some information. THX

- Mohammad Ali added an answer:How can I control the size of metal nano particles during their synthesis?
I will be thankful for sharing literature about size controlled synthesis of metallic nanoparticles and methodologies of capping of organic molecules on metallic NPs.
If it is biological synthesis, especially plant mediated, using plant extract in different concentrations strongly effect the size of NPs. Similarly, keeping the extract concentration constant and treating it with variable concentrations of Substrate e.g. Silver Nitrate, also effect the size of NPs.Following

- Alexander Loskutov added an answer:What are your overviews about the economic feasibility of applying synthesis of silver nanoparticles using plant leaf extract on large scale?
I am working since a while on the synthesis of silver nanoparticles using plant leaf extracts as other researchers along the world and I succeeded on this at lab scale. but I am interested now on exploring the possibility of the method being adopted at large scale and the economic feasibility of such adaption compared with the already established silver nanoparticles market providing large scale chemical and physical techniques?
The answer on your question requires more detailed information about the process of synthesis of NP (the speed of the process, the particle size, the output of the reduction reaction, the silver NP surface stabilization etc.). Sometimes one can do it very quickly and easily in the laboratory, but the development of industrial technology requires much more efforts and expenses. Very often, the duration of such work far exceeds the time spent on researches. I have one doubt in the success of such process in industry. The industrial technology usually requires strict compliance with all the conditions of synthesis (constancy of the chemical composition of the reactants and their concentrations). I am not an expert in the biology of plants and do not know whether they can meet these requirements.Following

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.

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

- 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
