Branched Alcohols

In our previous review an attempt has been made to relate the volumetric effects involved in the binary mixtures of normal and branched alcohols. This paper summarized some selected research activities of various authors related to complex molecular structure appearing in leading international journals. The main aim was better understanding of complex structure of different non-electrolyte mixtures with no alcohols, which are the most frequently present in chemical, petrochemical and related industries. The influence of the basic physical, chemical and structural effects of considerably chosen type of various binary and ternary mixtures was analyzed. These contributions are of primary importance for determination and modelling of thermodynamic, transport and other properties.

Analyze Data

A Virtual Instrument (VI) that is developed to acquire and analyze data from a physical system can be disconnected from the system and modified into a Virtual Experiment (VE). This can be achieved by replacing the input to the sensors with values that are arrived at by modeling the system. To be able to develop virtual experiments in thermodynamics, fluids or heat transfer, VIs are needed for the determination of thermodynamic and transport properties of different substances. The code REFPROP by NIST is used to develop the needed VIs for determining the thermodynamic and transport properties. The enhancement of the experimentation with virtual experiments is developed for an experimentation course where students perform experiments virtually and then make the transition to the actual lab and conduct experiments that mirror the virtual one.

Electron microscopic methods have been applied increasingly during the past fifteen years, to problems in structural molecular biology. Used in conjunction with physical chemical methods and/or Fourier methods of analysis, they constitute powerful tools for determining sizes, shapes and modes of aggregation of biopolymers with molecular weights greater than 50, 000. However, the application of the e.m. to the determination of very fine structure approaching the limit of instrumental resolving power in biological systems has not been productive, due to various difficulties such as the destructive effects of dehydration, damage to the specimen by the electron beam, and lack of adequate and specific contrast. One of the most satisfactory methods for contrasting individual macromolecules involves the deposition of heavy metal vapor upon the specimen. We have investigated this process, and present here what we believe to be the more important considerations for optimizing it. Results of the application of these methods to several biological systems including muscle proteins, fibrinogen, ribosomes and chromatin will be discussed.
