“…In the literature there is a lot of information concerning the preparation of microorganisms for synthesis of biofuels or sterilization materials for FAME production, such as algae [17][18][19][20][21]. During this processes structure of fatty acid chain can be changed, which will cause change in biodiesel properties.…”

The study of the influence of external factors on FAME is increasingly being taken up with research topics. Under natural conditions, they are subject to aging. However, such studies are time-consuming, and it is difficult to find the right aging inhibitors. In the presented work an attempt was made to apply ionizing radiation to induce changes in FAME. On the basis of GC-MS results, a reduction of mainly methyl esters containing C=C double bonds can be observed. This indicates the occurrence of polymerization reactions induced by radicals arising during the absorption of ionizing radiation.

“…The cellulose fibers transformed to a hemicellulose structure, which consists of short cellulose chains, due to the degradation of the O-C-O bond as a result of the E-beam stabilization (Fig. 5) [23][24][25][26].…”

Cellulose fibers were stabilized by treatment with an electron-beam (E-beam). The properties of the stabilized fibers were analyzed by scanning electron microscopy, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, and thermogravimetric analysis. The E-beam-stabilized cellulose fibers were carbonized in N 2 gas at 800°C for 1 h, and their carbonization yields were measured. The structure of the cellulose fibers was determined to have changed to hemicellulose and cross-linked cellulose as a result of the E-beam stabilization. The hemicellulose decreased the initial decomposition temperature, and the cross-linked bonds increased the carbonization yield of the cellulose fibers. Increasing the absorbed E-beam dose to 1500 kGy increased the carbonization yield of the cellulose-based carbon fiber by 27.5% upon exposure compared to untreated cellulose fibers.

“…ing and artificial aging b-Irradiation (e-beam) treatment is generally used to modify chemical and physical properties of cellulosecontaining materials (Henniges et al 2012(Henniges et al , 2013Driscoll et al 2009;Sarosi et al 2020). It has been proposed as pre-treatment of renewable lignocellulosic resources to improve monosaccharide yield for bioethanol production (Postek et al 2018;Chung et al 2012;Sundar et al 2014) or nanocellulose production (Kim et al 2016;Leskinen et al 2017;Eo et al 2016).…”

Comparative hydrolysis analysis of cellulose samples and aspects of its application in conservation science

Knowledge about the carbohydrate composition of pulp and paper samples is essential for their characterization, further processing, and understanding the properties. In this study, we compare sulfuric acid hydrolysis and acidic methanolysis, followed by GC–MS analysis of the corresponding products, by means of 42 cellulose and polysaccharide samples. Results are discussed and compared to solid-state NMR (crystallinity) and gel permeation chromatography (weight-averaged molecular mass) data. The use of the hydrolysis methods in the context of cellulose conservation science is evaluated, using e-beam treated and artificially aged cellulose samples.
