Scanning Transmission Electron Microscopy (STEM) and related techniques
มุมมอง 1.9K3 ปีที่แล้ว
The scanning transmission electron microscopy (STEM) is a technique that opens the possibility of performing atomic-resolution imaging and nanoscale analysis. This technique uses a focused electron beam to scan over the specimen in a raster pattern similar to the more widely known scanning electron microscopy (SEM). In contrast to an SEM, where a bulk sample is typically used, as STEM uses dete...
Atomic Scale Characterization of Materials in 3D: An Introduction to Atom Probe Tomography
มุมมอง 6373 ปีที่แล้ว
Atom Probe Tomography (APT) is very unique and powerful technique to study the materials at near atomic spatial resolution with sub part-per-million (ppm) chemical sensitivity and that too in 3-dimensions. In last two decades, APT has seen exceptional growth worldwide and the technique is pushing its limits with every passing day. Since last few years, the APT research in India is making its mo...
LC-QTOF technology and its applications in Metabolomics
มุมมอง 1.8K4 ปีที่แล้ว
High Resolution Mass spectrometry (HR-MS) has been utilized in metabolomics research due to its wide dynamic range, reproducible quantitative analysis, and the ability to analyze very complex biofluids. Due to the complex nature of these samples, separation (gas chromatography, liquid chromatography is often performed before MS. This talk will discuss about the QTOF technology and its advanceme...
Structure Determination of Peptides by simple 2D NMR Spectroscopy
มุมมอง 3.6K4 ปีที่แล้ว
Determining the three dimensional structure of biological molecules is an important step towards understanding the structure-function relationship. Structure determination of peptides or proteins is based on the Nuclear Overhauser effect (NOE) observed between two protons that may be less than 5- 6 Å apart (through space). The large number of protons present in a protein makes it almost impossi...

Very nice 👍
Thank you very much Madam. Very nicely explained.
Tnx ma'am nice explanation and I want to join event.
so helpful! amazing way of explaining!
Excellent lectures
how is this guy talking without moving his mouth??? #ventriloquist
Very Informative
Great talk ❤❤❤
Hello, how can I determine the penetration depth of electron beam?
By measuring the Energy of the ejected or back scattered electron also by the characteristic x-ray
This information was very helpful to understand.. I'm very thankful to sir 🙏
Hi sir good morning we have ICP thermo scientific here we getting sulphur higher side in all standards 2ppm, 10ppm, 50ppm, 200ppm including real also the sulphur is on high please tell me the problem
Thank You, sir, For clarifying all the doubts.
Very good information SIR
Nice lecture
Which source of x ray we use in both the Cases?
We don't use any X-ray source here. We use electron beam of SEM/TEM. This electron beam when fall on sample, the characteristic X-rays are generated which we use for either EDS or WDS Analysis.
In the video, the professor discussed that there is no X-ray source X-ray released as the electron occupies the nearest electron shell created when the electron displaces it from its position, and the energy is released in the form of an X-ray.

Very Informative presentation! Thank you sir.
NICE TALK I LEARN A LOT. THANKS
sir, Excellent EXPLANATION TO THE PEOPLE WHO ARE NEW TO INSTRUMENTS
Which one is superior icp aes or icp ms??and why ??m plz answer kariya ga
thank you for the great presentation I have a question. with our Anton paar system we noticed going to a temperature higher than 200oC, recovery of Ei in spiked samples at 03J and 1J will drop below 75%. but by keeping temp near 150oC we see good recoveries near 100%. we use 5mL HNO3 and 0.5 ml HCl and the sample amount is 20 mg. could you please comment and make a suggestion. regards mehrdad/Canada
Hi What type of rotor you are using.
@@rahul1anonly thank you for the reply i am using 8vessel quartz material 8NXQ80. if i use low microwave power (300-500) and make sure not to exceeds temp about 150oC, i see very good recovery from spiked samples. however at around 800 microwave power (that generate temp around 200oC) recovery drops to 80%. and at height power (1000) (temp ca 230oC) recovery drops below 70%. this observation is contradictory to the material in the video that recommends high temp to insure complete digression. your reply is appreciated.
Beautifully explained theory and practical aspects. Hats off you Sir.Amazing presentation .👏
Very nice explanation
Elaborate and useful information is presented. I would like to thank this channel for making it online. VERY HELPFUL
