In this work, we present a new, fast and high yield synthesis method for obtaining microcrystalline yttrium orthoferrite YFeO3, based on hydrothermal technique. The advantage of the method consists in the direct crystallization of the material without the necessity of the calcination. The quality of the so-obtained compound is checked by X-ray diffraction and XPS measurements. Unusual behavior of...
THz spectroscopy was used to investigate bovine serum albumin (BSA) flexibility in conditions ranging from lyophilised BSA to dilute 10% w/w BSA solution and highly concentrated 50% w/w BSA solutions. The simulated THz spectra of dry and hydrated BSA are in good agreement with the experiments.
The influence of the direct pumping into the 4 F 3/2 emitting level on the output characteristics of continuous-wave (CW) pumped, passively or actively (acoustooptic, AO) Q-switched Nd lasers is discussed. In case of passive Q-switching by Cr 4+ :YAG saturable absorber (SA) crystal, the change of pumping wavelength from 0.81μm into the highly-absorbing 4 F 5/2 ...
THz spectroscopy is a very powerful tool in investigating the vibrational modes and conformational transitions of biomolecules. Here we have used THz spectroscopy to study the vibrational spectrum of bovine serum albumin, a protein whose 3D structure is yet unknown. Experimental data were fitted with theoretical spectra obtained by normal modes analysis of BSA structures generated by homology modeling.
