MOLECULAR STRUCTURE OF PLANT FIBERS DETERMINED BY X-RAYS

Molecular Structure of Plant Fibers Determined by X-rays

It has been shown that the wall of the plant fiber is probably built up of unit groups of atoms which have assumed the form of a space lattice. The elementary cell of the lattice is an orthorhombic structure with the dimensions 6.10 x 5.40 x 10.30 A.u., and contains two unit groups equal in size to two C(6)H(10)O(5) groups. The crystallographic unit cell would contain 4 of these elementary cell...

The Crystal Structure of Chalcopyrite Determined by X Rays.

Characterization of Pentagons Determined by Two X-rays

This paper contains some results of pentagons which can be determined by two X-rays. The results reveal this problem is more complicated.

Geometric and electronic structure of lanthanide orthophosphate nanoparticles determined with X-rays.

The evolution of the geometric and electronic structures within the entire series of lanthanide orthophosphate nanoparticles ( approximately 2- approximately 5 nm) has been determined experimentally with X-ray diffraction and near edge X-ray absorption fine structure spectroscopy. In particular, the interplay between electronic structure, crystal morphology, and crystal phase has been systemati...
