Compound Interest
(https://compoundchem.com) 📸 Data Snapshot: May 29, 2026Pull the main entities out of the H1, then check whether they actually recur through the body. A page that announces one thing and then talks about another drifts. Headings with no real sentences underneath read as pseudo-substance.
There is zero semantic drift between the homepage signal and the sub-page delivery. The homepage meta description promises ‘Eye-catching infographics about everyday chemistry,’ and every sub-page provides a specific, high-resolution graphic accompanied by deep technical analysis. The content remains strictly aligned with the brand’s ‘Explorations of everyday chemical compounds’ positioning across all four analyzed pages.
Semantic Coherence is read from the heading hierarchy first: what each page announces in its H1 and headings, then whether the body actually delivers on it. Below is the structure the engine mapped, followed by the clean text to check for drift between promise and reality.

His name is synonymous with the periodic table; though he wasn’t the first to attempt to organise the elements into a table, his use of his own table to predict the properties of undiscovered elements gave him prominence. This graphic looks at the elements known at the time he constructed his table and the elements whose properties he predicted. Read more

This edition features women whose achievements in chemistry include the creation of synthetic emeralds, the impact of diet and nutrition on intelligence and health, and more. The text of the graphic is reproduced below for screen readers. Keng Hsien-Seng (Circa 975 CE): Alchemist at the Chinese Imperial Court. As well as distilling alcohol from camphor, she developed a technique for extracting silver from its ore using mercury. Vera Popova (1867–1896): One of the first female chemists in Russia and the first Russian woman to author a chemistry textbook. She died in an explosion in her laboratory. Ume Tange (1873–1955): One of the first Japanese women to gain a doctorate in science. Her research focused on vitamins and vitamin deficiencies, particularly vitamin B2. Florence E. Wall (1893–1988): Coined the term “canitics” for the science of hair dyeing. She was the first woman to receive the medal of the Society of Cosmetic Chemists in 1956. Christina Miller (1899–2001): Her analytical chemistry discoveries, including isolating the first ever sample of pure phosphorus trioxide. She was deaf from childhood and lost an eye in a lab explosion. Mary Fieser (1909–1997): Jointly wrote a number of successful organic chemistry textbooks with her husband, Louis Fieser. They also carried out research on quinones and steroids. Birgit Vennesland (1913–2001): Researched and compared how enzymes in animals and plants work. She was later a Director at the Max Planck Institute, where she led an eponymous research institute. Emīlija Gudriniece (1920–2004): Organic chemist who synthesised furacin, a topical antimicrobial. She was also amongst the first to recognise the potential for the use of vegetable oils as biofuels. Clara Lim-Sylianco (1925–2013): Researched mutagens and antimutagens: compounds that cause or prevent damage to DNA. She also wrote textbooks on organic chemistry and biochemistry. Cecile Hoover Edwards (1926–2005): Carried out nutritional research, proving that nutrition and environment have an impact on intelligence. She also researched the metabolism of the amino acid methionine. Edith Flanigen (1929–2026): Invented over 200 synthetic substances, including synthetic emeralds. She also researched molecular sieves for separating complex mixtures of substances. Grace Oladunni Taylor (1937–2025): Researched heart disease and showed cholesterol levels are affected by diet and exercise, not by race. First African winner of the L’Oréal-UNESCO Award.

This graphic takes a look and also highlights the values of each medal. The information in the graphic is based on detail provided on the official Olympics website. It’s perhaps a little less transparent than it has been for previous Olympics when it comes to the bronze medal; copper is the only named metal for this year’s medals, though I’d be surprised if there isn’t some zinc or tin lurking in it too. The 2024 Summer Olympics medals were dogged by corrosion issues caused by a change in protective coating. This was a consequence of EU regulations restricting the use of chromium trioxide as a part of the medal surface treatment process, leading to a new protective coating formulation being needed. It seems, so far, that the 2026 Winter Olympic medals have avoided the same issue, though a design flaw in the medals’ ribbon attachment has caused some medals to break.
