Physical Chemistry and Chemical Physics: A survey

2013
What is the subject of physical chemistry? How is this discipline structured and what are its sub divisions? How did this discipline evolve and what are its current hot topics? Answers to these and some other questions will be given in this brief overview article which also provides links for further reading.

Physical and Chemical Mutagenesis

2003
Important methods to artificially induce mutations are the use of chemical and physical agents. Most chemical mutagens are alkylating agents and azides. Physical mutagens include electromagnetic radiation, such as gamma rays, X rays, and UV light, and particle radiation, such as fast and thermal neutrons, beta and alpha particles.

Physical, Chemical, and Chemical−Physical Double Network of Zwitterionic Hydrogels

The Journal of Physical Chemistry B, 2008
Zwitterionic hydrogels are very promising for biomedical applications. They are usually copolymerized with other polymers to improve their mechanical properties often at the expense of their biological properties. In this study, physically cross-linked poly(sulfobetaine methacrylate) (polySBMA) hydrogels were prepared, and their physical properties ...

Chondronectin: Physical and chemical properties

Archives of Biochemistry and Biophysics, 1985
Chondronectin, the chondrocyte attachment factor, was purified from chicken serum and characterized as to its physical and chemical properties. From sedimentation equilibrium data it was found to have a native molecular weight of 175,800 +/- 800 and a subunit molecular weight of 55,540 +/- 800 in the presence of guanidinium chloride and cysteine ...

The physical and chemical properties of eumelanin

Pigment Cell Research, 2006
SummaryIn this article, we review the current state of knowledge concerning the physical and chemical properties of the eumelanin pigment. We examine properties related to its photoprotective functionality, and draw the crucial link between fundamental molecular structure and observable macroscopic behaviour.

Physical-chemical properties of ubiquitin

Biochimica et Biophysica Acta (BBA) - Protein Structure, 1980
The secondary structure of ubiquitin, the environment of its single tyrosine residue and its potential for interacting noncovalently with histone 2A or DNA, have been probed by circular dichroism (CD), ultraviolet absorbance, fluorescence and ancillary techniques.

Physical‐chemical studies of spectrin

Journal of Supramolecular Structure, 1978
AbstractIn recent years considerable progress has been made in the understanding of the structure and function of the red blood cell membrane. The protein spectrin, of high molecular weight and propensity for self‐association, appears to play a major role, in concert with actin, in maintaining the shape and integrity of the membrane.

Semiclassical Methods in Chemical Physics

Science, 1986
Semiclassical theory finds use in chemical physics both as a computational method and as a conceptual framework for interpreting quantum features in experiments and in numerical quantum calculations. The semiclassical description of one-dimensional dynamical systems is essentially a solved problem for eigenvalue and scattering situations and for ...
