The Death Dealers
''The Death Dealers'' is a 1958 mystery novel by American writer Isaac Asimov (later republished as ''A Whiff of Death'', Asimov's preferred title). It is about a university professor whose research student dies while conducting an experiment. The professor attempts to determine if the death was accident, suicide or murder. The novel was Asimov's first novel-length mystery (non-science fiction) story. He had already published several mystery short stories, later collected as ''Asimov's Mysteries'' (1968), in some of which the mystery was solved by applying known science. Asimov's previous two novels from his Robots series combined mystery with science fiction. Plot summary One Thursday afternoon, Professor Brade goes to visit his graduate student's laboratory. He finds Ralph Neufeld dead, having inhaled hydrogen cyanide. In his experiment, he had somehow used sodium cyanide instead of sodium acetate, both white powders. Later, Brade is questioned by Detective Doheny, who is in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isaac Asimov
Isaac Asimov ( ; – April 6, 1992) was an Russian-born American writer and professor of biochemistry at Boston University. During his lifetime, Asimov was considered one of the "Big Three" science fiction writers, along with Robert A. Heinlein and Arthur C. Clarke. A prolific writer, he wrote or edited more than 500 books. He also wrote an estimated 90,000 letters and postcards. Best known for his hard science fiction, Asimov also wrote mystery fiction, mysteries and fantasy, as well as popular science and other non-fiction. Asimov's most famous work is the ''Foundation (book series), Foundation'' series, the first three books of which won the one-time Hugo Award for "Best All-Time Series" in 1966. His other major series are the ''Galactic Empire series, Galactic Empire'' series and the ''Robot series, Robot'' series. The ''Galactic Empire'' novels are set in the much earlier history of the same fictional universe as the ''Foundation'' series. Later, with ''Foundation an ...

Associate Professor
Associate professor is an academic title with two principal meanings: in the North American system and that of the ''Commonwealth system''. In the ''North American system'', used in the United States and many other countries, it is a position between assistant professor and a full professorship. In this system, an associate professorship is typically the first promotion obtained after gaining a faculty position, and in the United States it is usually connected to tenure. In the ''Commonwealth system'', the title associate professor is traditionally used in place of reader in certain countries.UK Academic Job Titles Explained academicpositions.com Like the reader title it ranks above [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 understand 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 m ...

The Dust Of Death
"The Dust of Death" is a science fiction/mystery short story by American writer Isaac Asimov, first published in the January 1957 issue of '' Venture Science Fiction Magazine'' and reprinted in the 1968 collection ''Asimov's Mysteries''. Plot summary The Great Llewes (as he is invariably known) is an organic chemist who runs the successful firm of Central Organic Laboratories with an iron fist and a tendency to take credit for his employees' work. The employees at Central Organic spend a lot of time fantasizing about killing Llewes, but one of them finally decides to do it. Edmund Farley has just spent half a year setting up an industrial-scale chemical plant in the hydrogen/methane atmosphere of Titan, and now Llewes is taking the credit for that as well. On Space Day, the anniversary of the first successful space flight, Farley sneaks into Llewes's atmosphere room and coats the inside of the nozzle of a compressed-gas cylinder with platinum black (finely powdered platinum ...

Ozonide
Ozonide is the polyatomic anion . Cyclic organic compounds formed by the addition of ozone () to an alkene are also called ozonides. Ionic ozonides Inorganic ozonides are dark red salts. The anion has the bent shape of the ozone molecule. Inorganic ozonides are formed by burning potassium, rubidium, or caesium in ozone, or by treating the alkali metal hydroxide with ozone; this yields potassium ozonide, rubidium ozonide, and caesium ozonide respectively. They are very sensitive explosives that have to be handled at low temperatures in an inert gas atmosphere. Lithium and sodium ozonide are extremely labile and must be prepared by low-temperature ion exchange starting from . Sodium ozonide, , which is prone to decomposition into NaOH and , was previously thought to be impossible to obtain in pure form. However, with the help of cryptands and methylamine, pure sodium ozonide may be obtained as red crystals isostructural to . Ionic ozonides are being investigated as sour ...

Chemical Kinetics
Chemical kinetics, also known as reaction kinetics, is the branch of physical chemistry that is concerned with understanding the rates of chemical reactions. It is different from chemical thermodynamics, which deals with the direction in which a reaction occurs but in itself tells nothing about its rate. Chemical kinetics includes investigations of how experimental conditions influence the speed of a chemical reaction and yield information about the reaction's mechanism and transition states, as well as the construction of mathematical models that also can describe the characteristics of a chemical reaction. History The pioneering work of chemical kinetics was done by German chemist Ludwig Wilhelmy in 1850. He experimentally studied the rate of inversion of sucrose and he used integrated rate law for the determination of the reaction kinetics of this reaction. His work was noticed 34 years later by Wilhelm Ostwald. In 1864, Peter Waage and Cato Guldberg published the law ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Comparative Biochemistry
Biochemistry, or biological chemistry, is the study of chemical processes within and relating to living organisms. A sub-discipline of both chemistry and biology, biochemistry may be divided into three fields: structural biology, enzymology, and metabolism. Over the last decades of the 20th century, biochemistry has become successful at explaining living processes through these three disciplines. Almost all areas of the life sciences are being uncovered and developed through biochemical methodology and research. Voet (2005), p. 3. Biochemistry focuses on understanding the chemical basis that allows biological molecules to give rise to the processes that occur within living cells and between cells,Karp (2009), p. 2. in turn relating greatly to the understanding of tissues and organs as well as organism structure and function.Miller (2012). p. 62. Biochemistry is closely related to molecular biology, the study of the molecular mechanisms of biological phenomena.Astbury (1961) ...

Tenure
Tenure is a type of academic appointment that protects its holder from being fired or laid off except for cause, or under extraordinary circumstances such as financial exigency or program discontinuation. Academic tenure originated in the United States in the early 20th century, and several other countries have since adopted it. Tenure is a means of defending the principle of academic freedom, which holds that it benefits society in the long run if academics are free to hold and espouse a variety of views, even if the views are unpopular or controversial. History Tenure was introduced into American universities in the early 1900s in part to prevent the arbitrary dismissal of faculty members who expressed unpopular views. One notable instance was the case of the resignation of Brown University president Elisha Andrews, who advocated silver coinage to reduce the impact on Americans and farmers who owed larger and larger loans due to deflation.
