John R. Dunn
John Robert Dunn (May 12, 1930 – July 14, 2002) was a Polysar synthetic rubber research chemist Personal Dunn was born in Andover, Hants, England. In his youth, he attended the Andover Grammar School. He became a Canadian citizen in 1980. Education Dunn received his Bachelor of Science degree in chemistry in 1951 with first-class honors at King's College at the University of London. He completed his Ph.D. in physical chemistry at the University of Oxford in 1953. Career Upon completing his education, he sailed to Canada aboard the S.S. Scythia of the Cunard Line. Dunn joined the National Research Council (NRC) in Ottawa as a research fellow from 1953 to 1955. After this post, Dunn joined the Natural Rubber Producers' Research Association in England as a senior chemist. He remained in this position until 1962, when he returned to Sarnia, Canada to join Polymer Corporation (later Polysar). Dunn remained with the company for the next 30 years, holding various managemen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polysar
Polymer Corporation was a Canadian federal crown corporation established in 1942 to produce artificial rubber to substitute for overseas supply cut off by World War II. After the Japanese captured the Dutch East Indies in 1942, most of the world's supply of natural rubber was out of Allied hands. Due to the importance of rubber products for both modern life and modern warfare, the loss of such an important resource at this phase in the war was a crisis. A factory was established in Sarnia, Ontario, using German patents from an American licensee. Polymer produced approximately 3,300 tons of synthetic rubber from oil every month from when production first began at the end of 1943 to the wars end in 1945. Sarnia was chosen because it is the point of intake the most secure and reliable source of crude oil coming into Canada; a type suitable for the synthetic rubber making process. The site was also chosen due to the adjacent St. Clair River which provides the necessary water supply for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Andover, Hampshire
Andover ( ) is a town in the English county of Hampshire. The town is on the River Anton, a major tributary of the Test, and is situated alongside the major A303 trunk road at the eastern end of Salisbury Plain, west of the town of Basingstoke, both major rail stops. It is NNW of the city of Winchester, north of the city of Southampton and WSW of London. Andover is twinned with the towns of Redon in France, Goch in Germany, and Andover, Massachusetts in the United States. History Early history Andover's name is recorded in Old English in 955 as ''Andeferas'', and is thought to be of Celtic origin: compare Welsh ''onn dwfr'' = "ash (tree) water". The first mention in history is in 950 when King Edred is recorded as having built a royal hunting lodge there. In 962 King Edgar called a meeting of the Saxon 'parliament' (the Witenagemot) at his hunting lodge near Andover. Of more importance was the baptism, in 994, of a Viking king named Olaf (allied with the Danish king ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of London
The University of London (UoL; abbreviated as Lond or more rarely Londin in post-nominals) is a federal public research university located in London, England, United Kingdom. The university was established by royal charter in 1836 as a degree-awarding examination board for students holding certificates from University College London and King's College London and "other such other Institutions, corporate or unincorporated, as shall be established for the purpose of Education, whether within the Metropolis or elsewhere within our United Kingdom". This fact allows it to be one of three institutions to claim the title of the third-oldest university in England, and moved to a federal structure in 1900. It is now incorporated by its fourth (1863) royal charter and governed by the University of London Act 2018. It was the first university in the United Kingdom to introduce examinations for women in 1869 and, a decade later, the first to admit women to degrees. In 1913, it appointe ...

Physical Chemistry
Physical chemistry is the study of macroscopic and microscopic phenomena in chemical systems in terms of the principles, practices, and concepts of physics such as motion, energy, force, time, thermodynamics, quantum chemistry, statistical mechanics, analytical dynamics and chemical equilibria. Physical chemistry, in contrast to chemical physics, is predominantly (but not always) a supra-molecular science, as the majority of the principles on which it was founded relate to the bulk rather than the molecular or atomic structure alone (for example, chemical equilibrium and colloids). Some of the relationships that physical chemistry strives to resolve include the effects of: # Intermolecular forces that act upon the physical properties of materials ( plasticity, tensile strength, surface tension in liquids). # Reaction kinetics on the rate of a reaction. # The identity of ions and the electrical conductivity of materials. # Surface science and electrochemistry of cell membrane ...

Cunard Line
Cunard () is a British shipping and cruise line based at Carnival House at Southampton, England, operated by Carnival UK and owned by Carnival Corporation & plc. Since 2011, Cunard and its three ships have been registered in Hamilton, Bermuda. In 1839, Samuel Cunard was awarded the first British transatlantic steamship mail contract, and the next year formed the British and North American Royal Mail Steam-Packet Company in Glasgow with shipowner Sir George Burns together with Robert Napier, the famous Scottish steamship engine designer and builder, to operate the line's four pioneer paddle steamers on the Liverpool–Halifax–Boston route. For most of the next 30 years, Cunard held the Blue Riband for the fastest Atlantic voyage. However, in the 1870s Cunard fell behind its rivals, the White Star Line and the Inman Line. To meet this competition, in 1879 the firm was reorganised as the Cunard Steamship Company, Ltd, to raise capital. In 1902, White Star joined the Ame ...

Tun Abdul Razak Research Centre
The Tun Abdul Razak Research Centre, originally known as the British Rubber Producers' Research Association, carries out research into rubber and is funded by the Malaysian government. Early years: as the British Rubber Producers Research Association: 1938 to 1957 The British Rubber Producers Research Association was formed as a scientific research organization in 1938 'to understand rubber and in pursuit of this aim to mount a programme of fundamental research', since at that time the technology was almost entirely empirical.Biographical Memoirs of Fellows of the Royal Society (1999) vol 45 pp 185-194 It carried out fundamental work on rubber, which included the more general polymer science and the physics and mathematics of rheology and in addition contributed to early work on electronic computers. Prominent in the push for greater rubber research and the establishment of the association was Sir Eric Miller, who became chairman of the BRPRA. In 1939, it obtained its first prem ...

Sarnia, Canada
Sarnia is a city in Lambton County, Ontario, Canada. It had a 2021 population of 72,047, and is the largest city on Lake Huron. Sarnia is located on the eastern bank of the junction between the Upper and Lower Great Lakes where Lake Huron flows into the St. Clair River in the Southwestern Ontario region, which forms the Canada–United States border, directly across from Port Huron, Michigan. The site's natural harbour first attracted the French explorer La Salle. He named the site "The Rapids" on 23 August 1679, when he had horses and men pull his 45-ton barque ''Le Griffon'' north against the nearly four-knot current of the St. Clair River. This was the first time that a vessel other than a canoe or other oar-powered vessel had sailed into Lake Huron, and La Salle's voyage was germinal in the development of commercial shipping on the Great Lakes. Located in the natural harbour, the Sarnia port remains an important centre for lake freighters and oceangoing ships carrying car ...
