Abstarct. A reaction between carbon and boric acid has been carried out through a solid state reaction. The sample is heated at 400oC. Characterization tests were carried out with X-Ray Diffraction

Antisymmetry: Fundamentals and Applications

Symmetry is fundamental to understanding our physical world. An antisymmetry operation switches between two different states of a trait, such as two time-states, position-states, charge-states,

E. S. Fedorov Promoting the Russian-German Scientific Interrelationship

At the dawn of crystal structure analysis, the close personal contact between researchers in Russia and Germany, well documented in the “Zeitschrift für Krystallographie und Mineralogie”, contributed

Abstract The English crystallographer William Barlow is famous for two achievements, both published in German, in Zeitschrift für Krystallographie und Mineralogie between 1894 and 1901. They concern

On the History of the Discovery of the Subgroups of the Euclidean Group

In the kinematics literature and community it is commonly accepted that the first complete list of the subgroups of the Euclidean group is due to Herve, who in 1978, published a seminal paper on the

Centennial of X-ray diffraction: development of an unpromising experiment with a wrong explanation

In February 1912 in Munich, P. P Ewald, one of A. Sommerfeld's Ph.D. students, consulted M. Laue on matters related to crystal optics, his thesis subject. During the conversation, Laue conceived the

Protein crystallography from the perspective of technology developments

The development of PX has been accelerated by the invention and applications of recombinant DNA technology that can yield nearly any protein of interest in large amounts and with relative ease, and the X-ray free-electron laser sources and its applications in PX have shown great potential for revolutionizing the whole field again in the near future.
