This chapter summarizes the series of different developments and investigations on in situ coupling of rheology with small-angle scattering (rheo-SAS) measurements of colloidal particle suspensions. This coupling allows us to directly correlate microscopic particle–particle interaction with macroscopic suspension behavior under different physical and chemical environments. [...]

Apatite and zircon fission–track data from crystalline rocks collected along an east–to–west elevational profile across the Bucaramanga strike–slip fault in the Cepitá area and thermal history modeling show the four–stage thermal history of the southwestern Santander Massif of the northern Andes in Colombia. A 60 my phase of burial heating from the Late Jurassic to the Late Cretaceous was followed by three cooling phases beginning in approximately 65–60 Ma, which were related to regional tectonic events. [...]

By combining the normal practice for X-ray crystallography of collecting diffraction data at 100 K with neutron crystallography the structures of cryo-trapped enzyme intermediates have been determined, revealing the positions of the previously hidden hydrogens that are essential to a better understanding of the involved mechanism..

Infolded dentine (plicidentine) around the pulp cavities of the tooth roots is an ancient dental feature of fishes (sarcopterygians and actinopterygians) and several basal tetrapod groups. But, plicidentine is completely unknown in synapsids except some sphenacodontid pelycosaurs. [...]

During neutron grating interferometry measurements with a highly collimated neutron beam a pseudo-variation becomes visible in the acquired data. This pseudo-variation prevents the quantitative analysis of the acquired data, as the measured dark field data depends now on both the ultra-small-angle scattering as well as the properties leading to the pseudo-variation.
