Where can I find the physical property formulas of terminols as in the picture I shared. Therminol 66, Therminol 62, Therminol VP-3, Therminol....(for all therminol heat transfer fluids)

How does tillage affect the physical properties of soil and soil temperature and can tillage release pollutants in the soil?

If we acquire a tomography dataset, we can extract alot of physical properties from it, including porosity and permeability. These properties are not directly measured using conventional experiment. Instead, they are calculated using different image processing algorithms. To this end, is there any guideline on how to report such results in terms of significant digits?

Thanks.

Usually in physics mathematics we study and discuss invariance, symmetries of physical systems, under some changes the physical properties of a system do not change. Also may we discuss invariance, symmetries in literature, under some changes (changing the places of words) is it possible to observe the invariance of the meaning. For example let us study the sentence "To study music, we must learn the rules. To create music, we must break them." by Nadia Boulanger. There are four action words study, learn, create, break; by changing their places we may write 24 sentences To study music, we must learn the rules. To create music, we must break them. To study music, we must learn the rules. To break music, we must create them. To study music, we must break the rules. To learn music, we must create them. To study music, we must break the rules. To create music, we must learn them. To study music, we must create the rules. To learn music, we must break them. To study music, we must create the rules. To break music, we must learn them.

And we read them separately, what may we observe, how may the meaning of the sentence changes.

Carbon quantum dots are very promising for research. However, its purification and physical properties are not well covered, especially for its powdered form. The best way to get it is through filtration, then dialysis and finally freeze drying. Freeze drying protocols are sophistacted and for getting good cake and not a collapsed sample, the freeze drying parameters should be well defined. Fortunaltely, this might not be enough 😂 as still CQDs may still be hygroscopic and its properties differ according to the precursor and method of fabrication.

Here is a place where we can share findings and techniques for CQDs physical properties and techniques to get it in pure powder form.

Hello everyone,

I'm looking for a source or document that proves why the apparent stiffness of the joint which should be totally dependent on physical properties and stress states of the material, now has some relation with the smallest mesh size in the normal direction of the adjacent material???

In case of very fine meshing around the joint, this formula will provide a high stiffness which is not correct and affect the behavior.

Please let me know if you have a reasonable explanation with reference.

Many thanks

I would like to know your opinions on what is the best approach to perform a multiple regression analysis for the manufacture of a material. I have 50 components (columns) and the value of some of their physical properties, so in each record I have a certain combination of maximum 5 components (i.e. there are at most in 5 columns values, the others are 0) with their concentrations in the value.

I think that the most correct thing would be to first perform a grouping and then perform the regressions for each of them and thus be able to understand more precisely the impact that these components have on that response. If so or not, please let me know what kind of models you would use for this type of analysis as well.

Thank you very much for your collaboration and I hope you are doing well wherever you are.

Regards.

I'm trying to test the effect of dust on lung cells

I was thinking of getting 2 conditions as my negative control, one without anything and one with something that mimic dust in physicals properties without the actual dust

the closest I can think of is titanium dioxide

What do you think? or should I just stick with one negative control i.e. no dust

Thank you

nanoparticles synthesis and applications

Hi everyone.

I am interested in co-authoring with other researchers to expand my collaboration horizons. In particular, my expertise is associated with depth-sensing indentation tests (micro and nano) for studying the mechanical properties of nanostructured systems. I have exhaustively worked with experimental AFM-assisted nanoindentation testing, and also with numerical simulations of the depth-sensing indentation process by ABAQUS software. On the other hand, I have wide experience in the thin-film solar cells area. My experience in this field goes from experimental and theoretical analysis of devices performance (photovoltaic I-V performance) to the characterization of the components (thin films) physical properties (electrical, optical (spectrophotometry), structural (X-Ray diffraction), morphological (AFM and SEM) and chemical (SEM and RBS)). In general, I have a lot of experience with different materials characterization techniques.

Taking into account my expertise, I would like to know how to boost my collaboration possibilities (co-authoring) with other researchers in similar areas (or interdisciplinary). I would appreciate any comments or tips regarding this point. Please, feel free to share your experience!

Definitions of physics properties vary from physicists' opinions to the strict historical method used for energy, momentum, force, etc. There is just one method that serves to advance our understanding of the nature of the Universe. It is the strict historical method. It consists of writing an equation that expresses the defined property as equal to a combination of other properties that have been previously introduced to us by direct empirical evidence. The definition must be formed at the time that the property is introduced to us by its direct empirical evidence. This method maintains direct dependence upon direct empirical evidence. We learn what it is that direct empirical evidence is attempting to reveal to us. The result is a property definition that informs us what the property is. A common practice by physicists is to say that a property is "a measure of" some other property. That is not a physics property definition. It tells us that physicists do not know what that property is. No property is a measure of another property. All physics properties are measures only of themselves.

Imagination that came to me 2 years ago. Thinking about a single software in concrete that can give the accurate value of every property including workability, shrinkage, durability, mechanical properties etc by simply putting content, chemical and physical properties of all ingredients and other influencing factors. The base of this idea was to reduce time-consuming and costly experiments to know the behaviour of this material.

Hi! I am working on polymer nanocomposite membranes and their physical properties. Is it possible that metal nanoparticles enhance the swelling property of polymer but decrease the porosity? Or should it be increase in swelling leading to increased porosity? I am using ethanol displacement method to determine the porosity.

Nowadays, prediction of some physical properties of glasses, namely, density, Young's modulus, shear modulus, hardness, glass transition temperature, thermal expansion coefficient, liquidus temperature, and refractive index. Using (AI) become one of the effective methods to know more and more about the structure of the glass nature.

I need to know the values of the electron affinities of as many insulators as possible. But for thin films of about 1-40 nm thick.

I'm guessing that the electron affinity changes when it stops being considered as a bulk material (which limit I don't know either).

I am a novice student doing a research project on water absorption in polymer composites with sodium silicate coating.

I want to ask about how to determine the result of the percentage of water absorption which is the sum of the percentage gain in body weight and the percentage of dissolved matter lost

for example, the conditioned weight is 9.76 grams then the wet weight at the time of immersion for 24 hours is 7.05 grams. Because there was a reduction in weight, my specimen was reconditioned with the result that the reconditioned weight was 6.83 grams.

Is it true that the percentage increase in weight was -27.77% and the percentage of dissolved matter lost was 30.02%? Then to determine the percentage of water absorption, just add (-27.77%) + (30.02%)?

Is there something wrong with my calculations?

please help in that case. thank you

Among the plethora of biological modifications of proteins and nucleic acids, why is the phosphorylation process so universally abundant?

That is, compared to a variety of other possible molecular groups, is there a specific reason for biological systems to adopt phosphorus groups to the extent they do?

Is this just because of the abundance and metabolic economy of this group, or are there other considerations involved (e.g., bond energetics, physical properties, solubility etc.)

Or is this question itself misplaced? Please clarify!

Thank you :)

Hello,

As part of simulation of gases mixture and water, I need to calculate viscosity of the fluid components and I am using relationships proposed by Chung et al. (1988).

The irony is while I am able to validate that I have coded the relationships well for gases like methane, oxygen but when I am trying to do with water, there is drastic difference, especially for T between 300 K and 700 K.

In order to check if it is only in my case, I was able to find an article where the authors are closer than NIST/CoolProp data base.

I also need to evaluate conductivity and I have same issues for water. In the temperature range mentioned, the conductivity even goes negative in some regions.

I am not able to understand how come it shows this anomaly only in case of water.

May some one help in this regard.

Thanks

Hello,

I am working with quantum dots and I am trying to have a better understanding of the absorption spectra of them. I understand that the first absorption peak represents my dots and that I can extract a estimation of their sizes and repartition, however I am not sure to what correspond the absorption we can observed at lower wavelength (in red with a question mark in the file attached).

Is it ripples of the main absorption? is it smaller size dots? Is it something else entirely?

The main reason behind my question is that I try to find if there is a link between the peak to valley ratio and any physical properties of my dots. The valley value is influence by this part.

Thanks for anyone answers.

Hi ,

I am evaluating the potentials of using S2 imagery with spectral unmixing techniques to retrieve physical properties of beach sand, such as granulometry, humidity and possibly spectrafacies (intendend as discrete classes of mineral mixtures occurring along the Victorian coastline, Australia).

The endmembers I will use are processed based on my VNIR (350-1075 nm) field spectroscopy campaign (ongoing) and planned Vis-SWIR (350-2500 nm) lab-based spectroscopy of sand samples from cross-shore profiles.

I think I will use Linear Spectral Unmixing, depending of the level of intimate mix I will discover in my sand samples.

However, I find it hard to find good literature.

Any idea??
