Science undergraduates have come to accept the use of computers as commonplace. The daily use of portable sophisticated electronic calculators (some of them rivaling general-purpose minicomputers in their capa bi li ti es) has hastened this development. Over the past several years, computer assisted experimentation has assumed an important role in the experimental laboratory. Mini- and microcomputer systems have become an important part of the physical scientist's array of analytical instruments. Prompted by our beliefthat this was an inevitable development, we began several years aga to develop the curricular materials presented in this manual. At the outset, several objectives seemed important to uso First, insofar as possible, the experiments included should be thoroughly tested and error free. Second, they should be compatible with a variety of laboratory computer, data-acquisition, and control systems. Third, little or no previous background in either electronics or programming should be necessary. (Of course, such background would be advantageous. ) To satisfy these objectives, we decided to adopt a widespread high-level computer language, BASIC, suitably modified for the purpose. Furthermore, we have purposely avoided specifying any particular system or equipment. Rather, the functional characteristics of both hardware and software required are stipulated. The experiments have been developed using Varian 620 and Hewlett-Packard 2100 series computers, but we believe they are readily transferable to other commonly available computer systems with a minimum of difficulty.

This text is primarily intended for readers who have some background in chemistry and who wish to find out more about the ways in which computers and electronics are influencing the techniques of observing chemical systems, the acquisition of data, its storage, and its transmission from one location to another. Many important concepts - such as interfacing, data collection, data bases, information services and computer networks - are covered in an easily assimilated and comprehensive way.

The impact of computers on all rea1ms of Chemistry has been one of the most important factors in the deve10pment of this science during the last years. In recognition of this fact, in 1971, the "First International Conference on Computers in Chemi ca1 Research and Education", was held at DeKa1b, I11inois, USA. A second Conference took p1ace in Ljub1jana, Yugos1avia in 1973 and this third Conference in Caracas, Venezuela, in 1976. The aim of these conferences was to provide a high level forum for the 1eading researchers to exchange information at the frontiers of present day computer app1ications to the different fie1ds of Chemistry. The present "Third International Conference on Computers in Chemica1 Research, Education and Techno10gy", whose proceedings are pub1ished in the present vo1ume, was conceived, by means of aseries of invited 1ectures, as a survey of the present-date state of the art in some of the most relevant areas of computer app1ications in Chemistry.

It is now time for a comprehensive treatise to look at the whole field of electrochemistry. The present treatise was conceived in 1974, and the earliest invitations to authors for contributions were made in 1975. The completion of the early volumes has been delayed by various factors. There has been no attempt to make each article emphasize the most recent situation at the expense of an overall statement of the modern view. This treatise is not a collection of articles from Recent Advances in Electrochemistry or Modern Aspects of Electrochemistry. It is an attempt at making a mature statement about the present position in the vast area of what is best looked at as a new interdisciplinary field. Texas A & M University J. O'M.

White Preface to Volume 8 Experimental methods in electrochemistry are becoming more diverse. This volume describes many of the new techniques that are being used as well as some of the well-established techniques. It begins with two chapters (1 and 2) on electronic instrumentation and methods for utilization of microcomputers for experimental data acquisition and reduction. Next, two chapters (3 and 4) on classical methods of electrochemical analysis are presented: ion selective electrodes and polarography.

This new monograph provides a comprehensive overview of the state of the art of the automation of laboratory processes in analytical chemistry. The topics have been chosen according to such criteria as the degree of consolidation, scope of application and most promising trends.The first part of the book begins with the basic principles behind the automation of laboratory processes, then describes automatic systems for sampling and sample treatment. In the second part the principal types of analysers are discussed: continuous, batch and robotic. The third part is devoted to the automation of analytical instrumentation: spectroscopic, electroanalytical and chromatographic techniques and titrators. The last part presents some examples of the application of automation to clinical chemistry, environmental pollution monitoring and industrial process control.The text is supplemented by 290 figures and 800 literature references. It is written primarily for scientists directly involved in laboratory work and those responsible for industrial planning and control, research centres, etc. It will also be of interest to analytical chemists wishing to update their knowledge in this area, and will be of especial interest to scientists directly related to environmental sciences or clinical chemistry.

No decade before or since witnessed cultural, technical, and social changes as dramatic as the 1960s. Pop culture reflected a transition from the rigid 1950s to the permissive 1970s. The Vietnam War spawned student protests, draft card burning, and a hippie counter-culture. Caught up in these turbulent times was author Sam Perone, a naïve young professor beginning his career at the tender age of twenty-three?young enough to run in student circles. Perone's unlikely arrival in 1962 at a prestigious university?lacking credentials and experience?launched an erratic journey laced with angst, liberating diversions, exciting research, bitter conflicts, dismal failures, and exhilarating successes. In Turned On!, he shares his own life story against the backdrop of the times. A collection of personal experiences that characterize that turbulent decade, this memoir tells about the time Perone got tipsy during his university job interview; the weeks he slept in chemistry labs; the explosions, floods, flashes, pranks, and jolts that marked his early research; the wild parties fueled by lab alcohol; his unexpected ?love affair? in 1967 San Francisco; the sometimes serious, sometimes disturbing, and always laughable instances of faculty clashes; and finally his pivotal involvement in the minicomputer revolution. Turned On! describes a personal journey toward self-realization in a world that was rapidly changing in fascinating ways. It captures the impact on campus life of historical events that defined the 1960s, but also provides insights to the inner workings of the academic world in that era and beyond.

This handbook is prepared after extensive simulations of the circuits with some electronic and engineering software such as Multisim, PSPICE and Circuit Logic. This handbook is designed basically to assist both tutors and students in the conduct of laboratory experiments. It has been proven over time that students tend to remember experiments they conducted much more than lectures they received. This handbook was written in a simple technical language and the mathematics behind the experiments clearly derived and explained. This book is intended to add a wealth of knowledge especially in physics, Electrical and Electronic and communications engineering for students in tertiary institutions such as Polytechnics, Monotechnics and Universities. This handbook contains thirty-eight experiments which can be categorized into Basic Electrical and Electronics Engineering experiments, Analogue Electronics experiments, and Digital Electronics experiments. Each experiment contains details of objectives, materials, theoretical background and procedures. The procedure involves steps and questions in understanding of the experiment being conducted. At the end of the book, some individual projects are present with the aim that, students who have mastered the experiments in the book can design basic electronics to solve world problems.
