Nuclear chemistry, rebuilt like a textbook — and alive.
Eight units of CHEM7012 — from the liquid drop model to stellar nucleosynthesis — researched from the standard reference books, written in plain exam-focused language, typeset with real mathematics, and drawn as publication-grade vector figures. One page per chapter, with the PYQ bank audited question by question against the real papers — only questions that actually appeared count, and the page says so where none did.
Published chapters
One page per chapter, in syllabus order. Researched from the reference books — nothing invented, nothing padded.
Nuclear Properties & Structure I
The nucleus as a physical object: the liquid drop model, the semi-empirical binding-energy equation and its mass-parabola applications, nuclear reactions — Q-value and cross section — compound-nucleus theory, angular momentum, dipole and quadrupole moments, parity, and nuclear size.
Radioactive Equilibrium
Parent–daughter chains done properly: successive disintegration, the Bateman equation, secular, transient and no equilibrium — plus the formation of a radioelement in a nuclear reaction and an introduction to activation analysis.
Interaction of Radiation with Matter
What radiation does to matter: heavy charged particles and photons, energy loss and stopping power — collisional and radiative — the Bethe formula, mean excitation energy, range, slowing-down time, Cerenkov radiation and the attenuation coefficient.
Statistical Methods in Analytical Chemistry
Counting is a statistical act: probability and the binomial distribution, radioactivity as a statistical phenomenon, the standard deviation of counting data, the Poisson distribution, and how to optimise a counting experiment.
Thermal Methods
Reading a thermogram: thermogravimetric analysis (TGA) and differential thermal analysis (DTA) — what each curve really shows and where each method is applied.
Separation Techniques
Separations that work: chromatography — band broadening, column efficiency and resolution — gas chromatography and HPLC, numerical problems, then ionic liquids: synthesis, properties, applications, and the green-solvent story.
Environmental Chemistry
The chemistry of consequences: hazardous and radioactive wastes, their treatment and management, and the environmental footprint of fertilizer industries.
Cosmochemistry
Chemistry beyond Earth: geological systems, the age of rocks and of the Earth, cosmic rays and their fingerprints in meteorites, comets, black holes, nuclear reactions in stars, and the solar neutrino hypothesis.

How a syllabus unit becomes a chapter
A six-step pipeline, run the same way every chapter — the whole recipe lives in ARCHITECTURE.md so the next chapter (and the next agent) inherits it.
Research
The reference books are the spine: Harvey, Glasstone, Evans, Friedlander, Arnikar and Loveland for the nuclear core; Duval for thermal methods; Tundo and Sanghi for green chemistry; A. K. De for the environment.
Write plain
Concepts first, in the plain language of Indian textbooks: no ornament, every formula earned, exam-first ordering — the things that must be read and that come in exams.
Typeset & figure
Build-time KaTeX (zero client math JS), boxed results, and publication-grade vector figures on a colour-blind-safe palette.
Figure & instrument
Vector figures encode exactly one idea each — decay chains, stopping-power curves, chromatograms, thermograms — drawn on a colour-blind-safe palette.
Audit the PYQs
Real university papers OCR'd and hand-verified. Only questions that actually appeared enter the bank — otherwise it says so.

Why these notes read differently
Every chapter traces back to the reference books — Harvey, Glasstone, Evans, Friedlander, Arnikar, Loveland, Duval, Tundo, Sanghi, De. No made-up facts, no padded filler.
Plain language in the Indian-textbook tradition: the concepts that must be read, the derivations that come in exams, worked examples that train the hands.
Fragments, math tokens, figure standard, lab physics contracts and this motion system — all documented in ARCHITECTURE.md for the next chapter and the next agent.
Eight units. One honest map. All chapters live.
Researched from the reference books, written for the exam, typeset and figured — then audited against the real PYQs.
