VESTA Tutorial: Simulation of XRD patterns – Matrix transformation of {h k l} planes Miller indices

Image
This VESTA tutorial demonstrates the following: 1. How to download and analyze .cif (Crystallographic Information File) from Open Crystallographic Database using VESTA program? 2. How to simulate X-ray diffraction patterns in VESTA from the crystal unit cell volume? 3. How to interpret and view the lattice planes, d-spacing in a 3-dimensional way? 4. How to perform matrix transformation correctly, in {hkl} Miller indices planes? 5. Matrix transformation by using simple matrix multiplication followed by the location of the new Miller plane after the transformation.   6. Identification of Miller {hkl} planes from crystal dimensions and XRD patterns. 7. Correlates the unit cell dimensions, d-spacing and 2-theta (2θ) values.

Machine Learning – Types with Simple Numerical Examples Machine Learning – Types with Simple Numerical Examples 📘 1) Supervised Learning Meaning: Learn from labeled examples (inputs X with correct outputs y). Example: House price: Size (sq.ft) -> Price (lakhs). Train on (1000->50), (1500->75), (2000->100). Learned rule ~ Price = 0.05 * Size. Predict 1800 -> 90 lakhs. Has labels Prediction 🍎 1a) Classification (Supervised) Meaning: Predict a class label. Example: Fruit by weight (g). Bananas: 100,110,120. Apples: 150,160,170. New fruit 140. Means: Banana=110, Apple=160. Distances: |140-110|=30, |140-160|=20. Predict Apple (closer to 160). Yes/No or Category 📈 1b) Regression (Su...

MUSIQ – Create any musical tone, just with numbers - Frequency & Duration

Image
Understanding the musical note is not a complex one. Any basic unit of musical tone or a single musical note consist of a frequency and time duration. Frequency is expressed in Hertz (Hz) and Duration is expressed in milliseconds(ms).     Enter the number for frequency and duration...

Simulating Cyclic voltammetric curves

Image
Cyclic voltammetry is an imperative electrochemical analytical tool to probe the electrochemical characteristics, electrochemical kinetics and to assess the performance of the fabricated electrode materials for batteries, supercapacitors, fuel cells, biosensors, etc. It is also deployed to scrutinize the electrochemical signature of the pharmaceutical / chemical / biochemical compounds and nanocomposite materials, polymers, complexes, etc., as well as to explore the electron transfer process from energy storage to bio-medical applications.   It consists of three electrode cell assembly immersed in the electrolyte and a computer controlled Potentiostat is used to control the potential and to monitor the current. 1. Working electrode (WE) where the required redox reaction takes place. 2. Reference electrode (RE) to vary / monitor the potential (E, V) of the WE. Potential between WE and RE is varied at a pre-defined scan-rate, denoted as ν (V.s -1 ) ...
