Joseph Priestley born in 1733 discovered the gas that would later be named oxygen, answering the age-old question, “How do things burn?”
In 1806, a 6-kg meteorite carrying carbon-based, organic chemicals was identified for the first time. Studies of meteorites may lead to a better understanding the origin of the solar system.
Plutonium named: In 1942, a secret report was submitted suggesting the name “plutonium” for artificial element 94 since it followed neptunium and uranium (elements 93 & 92). In 1971, Darleane Christian Hoffman discovered small amounts of plutonium in a rock formation.
Two-dimensional NMR techniques already had advanced the study of protein structures in solutions. In 1988, Richard Ernst’s group published a report in Nature showing how NMR spectroscopy could be used to elucidate structure in three dimensions. Now, studies are underway to increase NMR sensitivity by 100-fold.
March is Women’s History month, honoring women such as Ellen Swallow Richards, American chemist who in 1876 created the Woman’s Laboratory at MIT where women could learn the rudiments of science.
Fiesta del Arbol (Tree Festival), Spain. Marks the day in 1895 when King Alfonso planted a pine tree near Madrid. When trees and other plants need a nutrient boost—fertilizers can help.
Joan Berkowitz, environmental consultant who tackled everything from preventing water pollution to the best ways to treat industrial waste.
Arnold Beckman, born 1900, invented the pH meter to help the California citrus industry measure acidity. The device revolutionized scientific instrumentation.
In 1970, the first nationwide Earth Day was celebrated in the U.S. as an environmental awareness event celebrated by millions. Green chemistry promotes the careful design of chemicals manufacturing processes to reduce the use of toxic components and minimize waste and energy use on Earth Day and everyday.
In 1997, paleontologists announced the discovery of a trove of fossilized dinosaurs in northeastern China. Using high-tech chemical instruments, Helen Vaughn Michel helped uncover the cause of the mass extinction of the dinosaurs 65 million years ago.
In 1969, a patent was issued for the catalytic converter, which uses chemical reactions to turn noxious emissions into less harmful gases. Originally invented by Eugene Houdry, chemical engineer Kathleen C. Taylor and others improved the device.
Bees rely on enzymes to create the world’s first ready-to-eat sweetener.
Water, a simple yet under-appreciated substance, is essential for life. It plays a key role the biological processes that occur in the human body as well as the process that plants use to convert sunlight into energy.
In 1852, English chemist Sir Edward Frankland presents the concept later known as chemical valence, a theory fundamental to understanding chemical structure. Frankland also was an advocate for clean water.
On April 21, 1994, astronomer Alexander Wolszczan discovered the first extrasolar planets, or planets located outside the solar system. Since that time, scientists have discovered at least 529 of these planets, which are also called exoplanets and have started to discover the gases that comprise their atmospheres.
Bromine, an element discovered in 1826 by Antoine-Jerome Balard and found in a dye extracted from Mediterranean snails, produces the vibrant purples and blues favored by the kings and emperors of antiquity.
On this date in 1919, the Ford Motor Company is reorganized, with the Ford family retaining full control. Today, Ford is one of many automotive companies exploring plug-in hybrids, flex-fuel vehicles and other technologies meant to curb greenhouse gas emissions.
The development of soy-based toners has greatly streamlined the process of recycling paper and has the potential to reduce significantly the environmental footprint of waste paper.
On this day in 1969, astronauts Neil Armstrong and Buzz Aldrin took the first steps on the moon and collected soil and rock samples. These samples, along with others from lunar exploration, have been used to study the question of whether the moon is wet or dry.
Chemistry is key to insecticide formulations.
The pristine environment of Yosemite National Park provides ideal circumstances to study the natural chemistry of a snow-melt fed river and evaluate the impact of human activities on the river downstream.
Patent issued (No. 895.729) in 1908 for Frederick Cottrell’s new method for cleaning up smokestack emissions. The method — called electrostatic precipitation — is still used today to remove pollutants from industrial waste flows.
Meteorites can carry amino acids, the building blocks of proteins—of life on Earth. What does the presence of these molecules in meteorites mean?
The blue gray mist that lingers over the Great Smoky Mountains National Park is created by both natural and artificial sources.
