New results concerning the behavior of cellulose acetate in solutions and films by means of CD measurements

Tapping into Synchrotron and Benchtop Circular Dichroism Spectroscopy for Expanding Studies of Complex Polysaccharides and their Interactions in Anoxic Archaeological Wood

“…The spectral characteristics vary depending on whether measured in solution or film, on the solvent type, on the degree of substitution and oligomer/polymer length (Table 1) [1,35]. In many cases (though not all) such transitions (and transitions of other polysaccharides in the <180 nm range) can only be directly investigated using vacuum-ultraviolet (UV) CD [13,36], most conveniently delivered using a synchrotron source (e.g., [23,24,26,[30][31][32][33][34][35][36][37]). A unique strength of SCD spectroscopy is its higher photon flux and extended vacuum UV region down to a wavelength of 125 nm, the latter being particularly useful for obtaining spectral measurements of unstained sugars, oligosaccharides and complex polysaccharides such as cellulose.…”

Influence of different factors of physico-chemical modification on structure and properties of hemp fibers

“…U tom smislu DRS metoda predstavlja vrlo bitan faktor u daljem istraživanju i uvoĎenju unapreĎenja u oblasti molekulske strukture polisaharida, jer omogućava istraživanja vezana za kretanje molekula u vremenskim intervalima od 0,1 ns-100 s. Pod tim se podrazumevaju izvesna pomeranja, kako ponavljajuće monomerne jedinice, tako i bočnih grupa sa odreĎenim dipolnim momentom [94][95][96].…”
