François-Marie Raoult: Past and Modern Look
Springer Science and Business Media LLC - Tập 6 - Trang 41-49 - 2001
Jaime Wisniak
The academic and research career of Raoult is an example of success against the odds. He was born into a family of modest means and made his academic career far from Paris, the center of scientific power and means. He did his research on the behavior of solutions in general, and electrolytes in particular, before the concepts of molecular association, salt dissociation, and molecular structure had...... hiện toàn bộ
Progress in Practice: Can Undergraduate Student Affiliate Groups Survive After the (Re)Energizers Graduate?
Springer Science and Business Media LLC - Tập 2 - Trang 1-2 - 1997
BRIAN P. COPPOLA
The collective memory of the work of undergraduate student clubs is often fleeting, perhaps even more so than the memory of some academic faculty committees! Unlike fraternal organizations, with which members still identify long after they leave their student years, undergraduate students in preprofessional clubs more naturally dis-identify with their organizations once they
Using Molecular Modeling in the Organic Chemistry Course for Majors
Springer Science and Business Media LLC - Tập 7 Số 5 - Trang 293-296 - 2002

Carnot Cycle Revisited
Springer Science and Business Media LLC - Tập 7 - Trang 127-131 - 2002
Enrique Peacock-López
Sadi Carnot stated that the efficiency of a reversible Carnot cycle is independent of the properties of the material used to run the cycle. Using this statement, all textbook discussions of the Carnot cycle use an ideal gas. Here, in contrast, we consider, in the spirit of the Caratheodory approach, a general analysis centered on the existence of an integrating factor that transforms an inexact di...... hiện toàn bộ
Progress in Practice: Organic Chemistry in the Introductory Course II. The Advantages of Physical Organic Chemistry
Springer Science and Business Media LLC - - 1997

Bridging the Gap: Understanding the Chemistry of CMP
Springer Science and Business Media LLC - Tập 5 - Trang 242-245 - 2000
Jason Keleher, Jie Zhang, Steve Waud, Yuzhuo Li
This laboratory exercise will expose upper-level undergraduate students to the aspect of chemistry known as Chemical Mechanical Planarization (CMP). CMP is used for the fabrication of computer chips and memory devices. Students investigate a representative slurry that is used for copper-based advanced integrated-circuit processes. More specifically, students monitor the generation of •OH through t...... hiện toàn bộ
A Safe Way of Performing Some Dangerous Experiments. I. Construction of a Safety Spoon
Springer Science and Business Media LLC - Tập 7 - Trang 81-83 - 2002
Vladimir M. Petruševski, Metodija Ž. Najdoski
The demonstrations of many remarkable experiments include a high safety risk (e.g. the reaction of large pieces of sodium/potassium with water; the reaction of potassium with liquid bromine; the reaction of sodium with concentrated sulfuric acid, etc.). Chemistry teachers and instructors are usually reluctant to perform experiments that include a hazard. As a result, a number of fascinating experi...... hiện toàn bộ
Modeling and Graphic Presentation of Acid–Base Titration Curves. Presentation of an Alternative Method
Springer Science and Business Media LLC - Tập 7 - Trang 339-346 - 2002
Günter Heil, Horst Schäfer
Titration curves for the acid—base–titration of polyvalent acids and bases and their mixtures can be created in a simple way and presented graphically. The method, an alternative to the existing procedures, shall be presented here for discussion. With the described method it is possible in an easy manner and for didactic purposes to show how the boundary conditions, such as concentrations, pKa val...... hiện toàn bộ
Lars Onsager (1903–1976), Chemist-Physicist, on the Silver Anniversary of His Death
Springer Science and Business Media LLC - Tập 6 - Trang 255-260 - 2001
George B. Kauffman
The Norwegian-born theoretical chemist-physicist Lars Onsager (1903–1976) received the 1968 Nobel Prize for Chemistry “for the discovery of the reciprocal relations bearing his name, which are fundamental for the thermodynamics of irreversible processes.” A recipient of numerous awards and honorary degrees, which he did not receive until relatively late in life, he taught at the Johns Hopkins and ...... hiện toàn bộ
A Study of the Oxidation Pathway of Adrenaline by Cyclic Voltammetry: An Undergraduate Analytical Chemistry Laboratory Exercise
Springer Science and Business Media LLC - Tập 2 - Trang 1-13 - 1997
LAURENT D. GILLES DE PELICHY, EUGENE T. SMITH
An undergraduate laboratory exercise to be used in an undergraduate instrumental methods course is presented for the electrochemical characterization of oxidation products of adrenaline. An objective of this experiment is to use information obtained through cyclic voltammetry and simulation software to develop a qualitative understanding of the oxidation mechanism of adrenaline.
