ResourceOn This Day - May 06 : Victor Grignard was born
He developed the use of organomagnesium halides, now known as Grignard reagents, as a new method to make carbon-carbon bonds. This important reaction is widely used in synthetic organic chemistry.

ResourceOn This Day – Jul 06 : Oil rig destruction
The Piper Alpha was the biggest and oldest oil platform in the North Sea. The fire was initiated by a gas leak, and 167 people died. This was due to inadequate maintenance and safety procedures, and since then significant changes and improvements in these procedures have been made.

ResourceOn This Day – Aug 06 : Mars rover landed
It arrived on the Red Planet after a 36-week flight for a two-year investigation. Curiosity is using its onboard chemistry lab (CheMin) to identify and measure the abundance of various minerals (drilled from rocks and scooped from the ground) to see if there really was life on Mars.

ResourceOn This Day – Sep 06 : John Dalton was born
He is considered the founder of modern atomic theory because he was the first to propose that matter was composed of particles called atoms. He also discovered that at boiling point all liquids have the same saturated vapour pressure – the foundation for ‘Dalton’s law of partial pressures’.

ResourceOn This Day - Oct 06 : Chemical from Coal Facility
The U.S.A uses coal instead of petroleum to produce acetic anhydride and other acetyl chemicals. These are important building blocks in the synthesis of a number of consumer products including plastics, textiles and photographic film.

ResourceOn This Day - Nov 06 : Ian Heilbron was born
He investigated the natural synthesis of vitamin A and D, and worked on penicillin. Heilbron later became a scientific advisor to the government, and was knighted in 1946 in recognition of his contributions to academic and public life.

ResourceOn This Day - Dec 06 : Nicolas Leblanc was born
He invented a method of making sodium bicarbonate from table salt (also known as sodium chloride, NaCl) that became one of the most important chemical processes of the nineteenth century.
-
ResourceOn This Day - Mar 05 : Emmett Culligan was born
He invented the Culligan water softener system, which made water softening available to home users. This system uses minerals called zeolites, which filter calcium (Ca), magnesium (Mg), and other metal cations from hard water.

ResourceOn This Day - Apr 05 : Synthesis of morphine
Morphine was first isolated from dried poppy resin in the early 1800s and remains the best drug for relieving severe pain. Morphine is named after Morpheus, the Greek god of dreams.
-
ResourceOn This Day - May 05 : Arthur Schawlow was born
His research focused on optics – in particular lasers and their use in spectroscopy. Schawlow shared the Nobel Prize in Physics in 1981 with Nicolaas Bloembergen and Kai Siegbahn for their contribution to the development of laser spectroscopy.

ResourceOn This Day – Jul 05 : George de Hevesy died
He was awarded the 1943 Nobel Prize in Chemistry for his work on radioisotopes and their use as tracers in studying the chemical processes within living systems. He also discovered the element hafnium (Hf) with Dick Coster in 1923.
-
ResourceOn This Day – Aug 05 : Seymour Lipsky was born
He was the inventor of high-performance liquid chromatography (HPLC), which is a technique used to separate, purify and identify molecules. It is a highly sensitive method with a range of applications, such as detecting the presence of performance-enhancing drugs in urine samples.
-
ResourceOn This Day – Sep 05 : Ludwig Boltzmann died
He was best known for his kinetic theory of gas particles. His statistical methods explained how properties of atoms could predict the visible properties such as thermal conductivity and diffusion. This helped to bridge the gap between the thermodynamics of a large system and at a molecular level.
-
ResourceOn This Day - Oct 05 : Dirk Coster was born
He co-discovered hafnium (Hf), an element that was a mysterious blank in the periodic table for many years. Hafnium is used to make control rods for nuclear reactors because it can absorb neutrons.
-
ResourceOn This Day - Nov 05 : 5000 year old beer
It was found at Godin Tepe in the Zagros Mountains of Iran, an important fortress on the Silk Road. Researchers found evidence of wine from around the same period, but it is thought that beer was the most popular beverage in lower Mesopotamia at the time.
-
ResourceOn This Day - Mar 04 : First carbon dating method
Radiocarbon dating is a method that uses the half-life of carbon-14 to determine the age of carbon-rich materials up to about 60,000 years old. Libby was awarded the Nobel Prize in Chemistry in 1960 for his work.

ResourceOn This Day - Jun 04 : French Chemical Society
The Society was originally modeled on the British Chemical Society, the precursor of the RSC. It seeks to foster the communication of new ideas and facts throughout France and across international borders.
-
ResourceOn This Day – Jul 04 : Ernst Beckmann was born
He is known for inventing the Beckmann thermometer – a device used to measure small differences in temperature, rather than absolute temperature. The thermometer typically covers a small range of 5 °C, but it is possible to estimate temperature changes with an accuracy of 0.001 degrees.
-
ResourceOn This Day – Sep 04 : Stanford Moore was born
He shared the Nobel Prize in Chemistry with Christian Anfinsen and William H. Stein in 1972 for their work on the structure of ribonuclease enzymes. These enzymes catalyse the degradation of ribonucleic acids (RNA) and are involved in the destruction of RNA viruses.
-
ResourceOn This Day - Oct 04 : Kenichi Fukui was born
His career was devoted to explaining the nature of chemical reactions. He shared the 1981 Nobel Prize in Chemistry for his investigation into the mechanisms of chemical reactions. Specifically, this was for his work on the role of frontier orbitals, which have loosely bonded electrons.
