X-ray crystallography is an extremely precise means of imaging the exact structure of a given molecule or macromolecule in a...
Rosalind Franklin received little recognition during her life for her contribution to discovering the structure of the DNA molecule. In later years, however, the scientific community learned the truth of how her x-ray crystallography images directly helped James Watson and Francis Crick complete their...
Introduction to single crystal X-ray analysis I. What is X-ray crystallography?a) The X-ray scattering of materials is caused by the electron density r, and the scattering amplitude is the summation of scattering wave from an each electron. The scattering intensity is proportional to the ...

What does suitable control mean in an experiment to investigate the effects of different light intensities on rate of photosynthesis? What was the purpose of Mendel's pea plant experiments? What do you see when a leaf and chlorophyll extract is held in the li...
In molecular engineering, a molecule is designed based on its desired application or function. For example, it may be a drug for treating a specific disease or a catalyst for a specific chemical reaction. Once the purpose of the molecule is defined then it’s components can be selected. An...

“Each protein or ‘drug target’ is produced in sufficient quantities to allow researchers to grow crystals that can be used to provide high resolution images using x-ray crystallography and the powerful x-rays generated by Diamond,” explains Frank von Delft, Principal Beamline Scientist at Diamo...
She made the images with a technique called x-ray crystallography, which involves firing x-rays through a crystal to determine the arrangement of the atoms in it. It is a bit like determining the shape of a jungle gym from its shadow. Born in 1910, Hodgkin spent the first few years of...
What led to the development of x-ray crystallography? From what we know today, which of the postulates of atomic theory have needed to be altered? What is the drawback of Rutherford's experiments? What experimental evidence led Thomson to develop his atomic model? What was the reasoning...
