INVESTIGATION OF PROCESSING-STRUCTURE-PROPERTY RELATIONS IN VAPOR PHASE MODIFIED CELLULOSIC MATERIALS
Cellulosic materials are widely used in our daily lives for paper products and functional polymers. The cellulose molecule has a high density of hydroxyl groups, which causes strong intra-/inter- fiber hydrogen bonding. These abundant hydroxyl groups make cellulose super-hydrophilic and difficult …

Application of cellulosic materials as flexible substrates for two-dimensional electronic heterostructure devices
With the goal of creating a set of materials to enable flexible electronics, two-dimensional (2D) materials are incredibly capable. This family of nanomaterials comprises a suite of strong and flexible conducting, semiconducting, and dielectric materials. These materials, all compatible with one …

Effects of AFEX Pretreatment, Denisifcation and Storage on Ethanol Yields of Corn Stover, Switchgrass and Prairie Cordgrass
… It is most cost-effective to transport densified cellulosic materials; however this can be cost prohibitive. AFEX pretreatment coupled with an innovative densification method allowed reduced costs per unit. Five conditions were examined: untreated (control), AFEX pretreated, pretreated/densified, …

Continuum Mechanics Modelling of Corrugated Board
… method for the transient moisture flow in porous cellulosic materials like paper and wood is examined. The derivation of the model is based on mass conservation for a mixture containing a vapour phase and an adsorbed water phase embedded in a porous solid material. A model for the development of …

Impact of low-temperature storage on quality of high-moisture corn grain
… second-generation bioethanol is generated from cellulosic materials such as corn stover. Early harvesting of corn can increase the yields of grain and stover and reduce the lignin content of the stover and as a result, can reduce the major costs of feedstock and stover pretreatment in …
