“…Generally, the pretreatment process leads to produce both of the liquid and solid fractions of biomass that mostly contain lignin fragments and different forms of carbohydrates [16,17]. The solid fraction is mostly enriched with cellulose, while the liquid phase contains several sugar-based degradation compounds such as furan compounds and organic acids like levulinic and formic acids.…”

The key factor in lignocellulosic biorefinery is to extract maximum sugars from biomass as feedstock for the process of fermentation. The major barrier in extracting the sugars is the presence of lignin of biomass that primarily restricts the accessibility of cellulose to enzymes. Therefore, it is important to locate the presence and morphology of lignin to assess the reaction severity. In most of the severe pretreatment conditions, lignin is observed to condense and form spherical droplets on the surface of treated biomass. Such formation of pseudo-lignin differs in the action of cellulose hydrolysis from that of the initial or residual lignin content of biomass. In view of that, the present review is focused on the impact of various pretreatment techniques on the morphological changes in lignin and its subsequent redeposition or redistribution effect towards enzymatic hydrolysis process. Initially, the effect of different pretreatment methods is assessed which primarily resulted into the occurrence of lignin redeposition on the surface and interior of biomass. Thereafter, an in-depth insight is provided to understand the underlying mechanism of such formations of pseudo-lignin under severe reaction conditions. Finally, the study is concluded discussing the future recommendation to circumvent the interference of pseudo-lignin on enzymatic reactions. Hence, the present review article will not only help the readers to gain the knowledge on the formations and problems of pseudo-lignin obtained from biomass but also details the latest advancements that are involved to overcome the inhibitory effect of pseudo-lignin during the enzymatic hydrolysis of biomass. Highlights• The ultrastructural morphology of pseudo-lignin in the form of droplets are discussed.• The various pretreatment processes that are responsible for the formation of pseudo-lignin are described.• An insight on the reaction mechanisms is provided for the impact of pseudo-lignin towards enzymatic hydrolysis.• Advances processes to overcome the inhibitory effect are comprehensively summarized.• Associated challenges and future recommendations are demonstrated.

“…Huang et al investigated the buckling of internally cracked square plates [20], and Xue et al analyzed the vibrations and the buckling responses of cracked rectangular Mindlin plates [21]. Huang et al studied the vibrations and the buckling responses of threedimensional (3D) internal and side-cracked, functionally graded material (FGM) plates [22], as well as preloaded 3D internal and side-cracked FGM plates [23], by means of the Ritz method, utilizing admissible corner functions, formed by the moving least-squares approach or the MLS-Ritz method. Kiani and Krzysztof [24], investigated vibrations of double parallel defected nanorods, by utilizing the nonlocal surface energy principium and the Galerkin method.…”

The dynamic analysis of cracked thin rectangular plates subjected to a moving mass, first is investigated in this paper. To this end, the eigenfunction expansion method is utilized to solve the ruling differential equation of motion. For the first time, intact plate orthogonal polynomials, in the combination with the well-known corner functions, as a composition, are employed in the governing equation, required the professional computer programming, to solve the equation. The proposed solutions, afford upper bounds for the true solutions, which is a property of an appropriate numerical solution. Parametric investigations, are performed to determine, effects of moving mass weights, moving mass velocities, crack lengths, crack angular orientations, and plates' aspect ratios, on dynamic responses of cracked thin rectangular plates. The results confirm, that the moving mass, has a greater impact, than the moving load on dynamic responses of cracked thin rectangular plates. Furthermore, there are non-monotonous nonlinear relations, between altering dynamic responses of cracked thin rectangular plates with various boundary conditions, and modifying moving mass weights, moving mass velocities, crack lengths, inclined crack angles, as well as plates' aspect ratios respectively.
