Surface functionalization of cellulose nanocrystals derived from waste newspaper for highly efficient Mn (VII) sorption
Published 2025-07-01“…Abstract This study aims to produce functionalized cellulose nanocrystals (FCNCs) by preparing and functionalizing cellulose nanocrystals (CNCs) from eco-friendly newspapers utilizing a straightforward two-step reaction with an anionic polymer (poly hydrex 6161). FCNCs' structure is described using FTIR, XRD, and SEM. A pseudo-second-order model was used to describe the sorption kinetics of Mn(VII) onto FCNCs, and the results of the linear and nonlinear regression analyses agreed well (R2 > 0.999). …”

基于线性输入输出关系的空间连杆机构设计
Published 2012-01-01“…With respect to the designing requirements and constraints of the mechanism,two options,the RSSR mechanism and the dual-RSSR mechanism,are constructed based on CATIA with the top-down design ideas.The kinematic simulation of the model is conducted.The motion transmission characteristics of the two schemes are compared.A conclusion is drawn that for either RSSR mechanism or dual-RSSR mechanism the input and the output keep linear under the condition that the input angle is small.And for the dual-RSSR mechanism the output is approximately the same as its input by optimizing parameters of the mechanism structure.But for RSSR mechanism,those depend on the initial condition.…”
