I have functionalized a material with an organic compound and performed different analyses such as TGA, XPS, elemental analysis (by EDS and varioMICRO) but I have a difficulty to determine the general formula. Is there any equation?
Relevant answer
Answer
Reconcile elemental analysis for all methods. Determine the mass average. Write a formula, such as water or hydrogen peroxide. You have determined 12% hydrogen and 88% oxygen. Write the unknown formula HxOy. Find the ratio x: y and, resulting in an integer ratio
12/1: 88/16 = 12: 5.5 = 2: 1. Hence, you have identified water, not hydrogen peroxide.

Dear Çağlar Tilkicik, to shortten the way with least efforts, I advise you to follow three strategies:
- study (not read) reviews and Books
- Attending scientific forums and conferences
- work with and engage students in research, term papers, and supervision
I did this since I was graduate students. Good Luck and My Regards

I am working on a natural polymer and functionalized it to block the UV rays. However, I don't know any quantitative or qualitative test to study the UV blocking efficiency of my functionalized material and comparing it with control.
Please suggest me any lab suitable test for this
Relevant answer
Answer
You need to test the item in a (UV) spectrometer of some sort. A standard chemical / biological spectrometer system could do the job, there is usually one in a lab somewhere at a university. If there is not one available, a small system like this:

I use spectroscopic ellipsometry to determine the film thickness and refractive index of oxide thin films on silicon with VASE software from JA Woollam. The thing is i am not able to extract the dielectric function of the material film layer although the software gives combined pseudodielectric function of all the layers. 
Relevant answer
Answer
Hello Jagannath,
I use this software almost everyday.  If you want all the optical constants to be expressed as epsilon1 and epsilon2 (dielectric function), you have to change the defaults values in VASE:  in VASE, go to 'global' (top right in the menus), select 'defaults', and choose 'e1 and e2' for 'Specify Optical Const. in'.  After this selection is made, all the optical constants will be expressed in e1 and e2, including the results of your fits.
Hope that this solve your problem.  Let me know.

The porous metal organic framework material is very popular as an innovative functional material. The flexible tetra-carboxylic acid is one type of chelate ligand, barely used to construct metal-organic framework. The rigid di-carboxylic acid is one type of efficient ligand to construct transition metal-organic framework. However, both of the two acids are unable to meet the high coordination demand of rare earth, therefore, it is very difficult to construct a stable porous framework by using the two type of ligands alone.  By using flexible tetra-carboxylic acid and rigid di-carboxylic acid, will some new porous and stable MOFs be prepared? Thank you for your review on this project.

  1. In Field Emission measurement Eturn ON (threshold voltage), Jmax (maximum current density) and Beta (field enhancement factor) are main important parameter......What is more important?
  2. Where Beta is directly dependent on surface morphology but some scholars calculating it with the help of work function of the material ..... What is most appropriate method to calculate Beta? 
Relevant answer
Answer
It must be remembered that of the three named parameters, only one - Beta - is a model, a virtual setting. The remaining ones are determined by measuring the experimental values - currents. Beta is introduced to configure model law Fowler-Nordheim to describe the experimental data. Beta depends also on the geometry of the emitter surface, and the properties of the composite material.

In electrochemistry, electrolysis for instance, Nernst equation gives the final point of the process. It is determined by the Galvanic potentials of the inactive electorde and the templating metal, temperature, and the activity of the solution/electrolyte. If the inert electrode is semiconductive (i.e. transition metal oxide), I am wondering whether the Galvanic potential is marked by the work function of the material, or whether there is any relationships between the two properties of the material. 
Relevant answer
Answer
Regardless of the material, the work function is the the difference in energy of an electron between vacuum level and the Fermi level.  The Fermi level is indeed the same as the electrochemical potential of the electron in the solid. Since the Nernst equation does nothing else but defining how this potential, E, shifts with respect to E(0), i.e. the electrode potential under standard conditions, it is a direct measure for how the work function changes upon polarization of the electrode. The problem is that different energy scales are used. The work function and Fermi level are usually defined against the vacuum level, while the electrode potential or redox potentials in electrochemistry are defined against an arbitrary zero, which is the standard hydrogen electrode (SHE). If you can establish the difference between 0V versus SHE and the vacuum level, then the Nernst equation could be used directly to calculate changes in work function. I believe there are several approaches to this, and you can learn more about it if you look up papers that aim to develop an "absolute scale" of redox potentials. I believe Wolfgang Schmickler has done some work on this.

Carbon fibre based composites show various advantages (light weight, less prone to corrosion, etc..) over Steel and other structural materials. For example Carbon fibre composites are already being used in cars and aerospace industries, do you think they can be used in buildings, bridges, etc...
Relevant answer
Answer
The question is general, so the direct answer is "no":
CFRP will not "generally" replace steel ...
... but it may do so in certain applications, and these may well be numerous. Michael Heine gave a lot of good examples. However, look for Prof. Hufenbach often-cited statement (which has in fact been made by many people, probably also in parallel) - "The right material in the right place at the right price and with the right ecology".
If you follow this thought, the future is likely to be hybrid, or multi-material, and the proportions of indivdiual materials like steel or CFRP will shift with time even for a
given application: There are the usual boundary conditions, e.g. with respect to the link between cost, process and series size, which may be altered e.g. by introduction of new processes or optimization of old ones, there are raw material prices which may even be politically influenced, and there is a ecology, which as a cost factor is very much determined by regulations .... and there are of course certain aspects steel can provide, which CFRP can't as well. Anisotropy in CFRP has been mentioned, which can be employed to advantage of course but may be a problem in other scenarios, impact performance may still turn out to be an issue in aerospace, and potential also in automotive applications (repair, damage detection, crashworthiness etc.), high temperature performance of steel vs. CFRP etc. And naturally there is also the development potential steel may still have: When Audi introduced aluminium on a larger scale in the A8 and later the A2, it turned out that steel could in fact compete: There were the ULSAB projects, and there were the developments towards TRIP and TWIP steels, to name but a few.
All such developments can be imagined for the building industry, too, hence there is surely a potential and thus a market for the material, but none to replace all that's there today.
Lest I forget to mention, if you would like to have an overview of recent developments in terms of materials for transport applications, why not have a look at this ;-)
Hope you find it interesting, even though the building topic is not covered.

Apart from electron energy loss spectroscopy (EELS), what are the other techniques that can give light elements (such as Lithium) distribution profile (2D Mapping) with high resolution?
Relevant answer
Answer
Dear Sir,
just try to get access to a OMICRON NanoESCA, preferably mounted at a synchrotron beamline. Then, you will get chemical information via X-ray photoelecron spectroscopy (XPS) with lateral resolution in the range of 100-200 nm. In case you can identify Li in your batteries via changes in workfunction, the PEEM mode of the NanoESCA provides spatial resolution in 2D mapping in the range of 50 nm.
Unfortunately, these devices are not widly used and synchrotron radiation seems mandatory since in XPS the problem for Li is the same as in case of EDS/EDX, namely very low cross sections.
For further information, see
Sincerely,
FM
