In this installment of the Ask the Experts series, Chemistry, our professors, scientists, and researchers tackle reader questions about the substances that compose all matter, their properties, and how they interact and change. Queries range from elementary questions, such as why some elements change color over a flame, to how chemistry works in everyday life, to how certain substances affect the body and more.

Multi-volume work on science edited by Francis Rolt-Wheeler. The fourth volume is on Chemistry written by William Allan Hamor. It discusses the development of chemical knowledge, from the ancients to modern times. It expanded further on the early works of alchemists and into the phlogistic period. The last chapters cover atomic theories and the development of organic and inorganic chemistry. - Summary by Sienna

Full-Length ACS Organic Chemistry Exam Simulation: a complete timed exam built to mirror the real ACS Organic exam in structure, content distribution, and question difficulty—based on published ACS blueprints.

The following is the audio track for the 1953 promotional animated short documentary film created by John Sutherland and sponsored by General Electric explaining what an atom is, how nuclear energy is released from certain kinds of atoms, the peacetime uses of nuclear power, and the by-products of nuclear fission.

Full-Length ACS-Format Exam Simulation — one complete timed exam mirroring real ACS structure, content distribution, and difficulty based on published blueprints. Not generic practice. The right content, the right proportions, the right format.

Don't buy just a book. Buy a system backed by brain science. Still blanking on the citric acid cycle steps under pressure? Mixing up competitive and noncompetitive inhibition? Recognizing answers in practice but freezing when you have to generate them? That's not a knowledge problem. That's a method problem. This book fixes the method. Step 1: Read It. Build Your Foundation: Every Part opens with a comprehensive Study Guide before you touch a single problem.

Interested in chemistry? Then you're in the right place. Substances Up Close is a chemistry podcast about the substances that shape civilization and everyday life, from iron and sulfuric acid to polyethylene and vitamin C. My name is Denis Koshevoi, a chemist and chemistry tutor, and I'll be your host.The concept is simple: one episode, one substance. In each episode we’ll explore a substance: its properties, the history behind it, and how it’s used. You’ll also learn important chemical concepts and, from time to time, some practical tips that will help you stay informed and make your ...

A fascinating look back at the state of the art of chemistry 100 years ago, this book by James C. Philip, PhD, an assistant professor of chemistry at The Imperial College of Science and Technology, Kensington, provides a "description in non-technical language of the diverse and wonderful way which chemical forces are at work, and their manifold application in modern life" in 1910. Professor Philip relates many of the key chemical discoveries of early academic researchers in the context of the practical uses to which these discoveries were applied in the early 20th century. (summary by J. M. ...

Joseph Priestley, FRS was an 18th-century English theologian, Dissenting clergyman, natural philosopher, chemist, educator, and political theorist who published over 150 works. In “Experiments and Observations on Different Kinds of Air,” he reviews experiments with gases. A common theme in this work is measuring the volumes of gases held in glass tubes, and their increase or decrease when exposed to other substances. He also tests the effects of gases on mice, plants and insects. Priestley demonstrated that fixed air (now known as CO2) can be produced from several reactions including ...

The Chemical Constituents of Piper Methysticum or The Chemical Constituents of the Active Principle of The Ava Root is the text of a Master’s Degree thesis presented in June 1915 by Alice A. Ball. Ms. Ball was the first woman and African American to receive a Master’s Degree from the University of Hawaii. Her thesis includes some history of the use of the ava (kava) root in the South Pacific islands along with the isolation and analysis of the extracts of the kava root and some preliminary observations of its effects when administered to animals. - Summary by J. M. Smallheer

A description of the properties and effects of the principal components of Varnish and the best means of employing them. - Summary by Preface

Published in 1911 as part of the "Harper's Library of Living Thought," this volume presents an introduction to the chemistry of cells in the context of plant physiology and gives an interesting overview of the field of biochemistry and related sciences at the time. The author, Frederick Czapek, was a Czech botanist and professor of Plant Physiology at the University of Prague. He is perhaps best known for his two-volume work on Plant Physiology, "Biochemie der Pflanzen" and for Czapek solution agar or Czapek-Dox medium, a culture medium for cultivation of fungus species such as Aspergillus and...

What if a 1973 Opel with a stock engine outperforms a cutting-edge hydrogen fuel cell car? In this podcast, we dive into the physics of energy efficiency — exploring how a humble GM/Shell vehicle achieved 376 mpg through continuous waste heat recovery and steam implosion, while Toyota's Mirai relies on regenerative braking that only kicks in when you stop. We break down why recovering heat you were going to throw away anyway might be the most underrated idea in automotive engineering — and what it means for the future of clean mobility.

Killer Chemistry is a true crime podcast hosted by investigative journalist Callie Lyons, uncovering the hidden dangers of environmental toxins. Explore toxic exposures rooted in military science that continue to affect millions. This gripping series reveals a silent killer’s impact on generations and the coverups that kept the truth buried, blending true crime with scientific investigation.

Die moderne Physik hat die Medizin umgekrempelt. Ärztinnen und Ärzte können heute ganz selbstverständlich in den lebendigen Menschen schauen – ohne den kleinsten Schnitt in die Haut. Verletzungen und Erkrankungen lassen sich damit so präzise erkennen wie nie zuvor. Und sogar Heilen kann die Physik! Wo eine Operation nicht ausreicht, können verschiedene Arten von Strahlung etwa Tumore bekämpfen.
