Electrospun nanofibers of poly (vinyl alcohol) (PV) were obtained to improve dispersion of cellulose nanocrystals (CNC) within hydrophobic biopolymeric matrices, such as poly(lactic acid) (PLA). Electrospun nanofibers (PV/CNC)n were successfully obtained with a final concentration of 23% (w/w) of CNC. Morphological, structural and thermal properties of developed CNC and electrospun nanofibers w...

Polyethylene (PE) nanocomposites containing Cellulose Nano Crystal (CNC) were prepared via melt blending in a twin screw extruder. The evaluation of PE/CNC nanocomposites was studied for food packaging applications. The nanocomposites were investigated by thermal, mechanical analyses. Addition of CNC particle while having no effect on melting and crystallization temperature had intensive effect...

The coefficient of thermal expansion (CTE) of cellulose nanocrystal (CNC) films was characterized using novel experimental techniques complemented by molecular simulations. The characteristic birefringence exhibited by CNC films was utilized to calculate the in-plane CTE of self-organized and shear-oriented self-standing CNC films from room temperature to 100 °C using polarized light image corr...

We introduce the Concurrent Collections (CnC) programming model. CnC supports flexible combinations of task and data parallelism while retaining determinism. CnC is implicitly parallel, with the user providing high-level operations along with semantic ordering constraints that together form a CnC graph. We formally describe the execution semantics of CnC and prove that the model guarantees dete...

cellulose nanocrystal (cnc) is a type of nanomaterial which is produced by partial hydrolysis of cellulose and elimination of its amorphous regions. cnc has several advantages such biodegradability and safety toward human health. in this study, cnc was produced from cotton linters and methods such transmission electron microscopy which were used for confirmation of nanoscale size production of ...

X-linked Opitz syndrome (XLOS), caused by mutation in the MID1 gene, is a midline malformation syndrome with obvious craniofacial abnormalities. Because cranial neural crest cells (CNC) play a pivotal role in cranial morphogenesis, we examined the spatio-temporal expression of cMid1 in chick embryos and investigated if alterations in Mid1 protein function, specifically the ability of Mid1 to ne...

Reaction of [AuCl(PPh(3))] with the zwitterion S(2)CNC(4)H(8)NH(2) yields [(Ph(3)P)Au(S(2)CNC(4)H(8)NH(2))]BF(4). Treatment of this species with NEt(3) and CS(2) followed by [AuCl(PPh(3))] leads to [{(Ph(3)P)Au}(2)(S(2)CNC(4)H(8)NCS(2))], which can also be obtained directly from [AuCl(PPh(3))] and KS(2)CNC(4)H(8)NCS(2)K. A heterobimetallic variant, [(dppm)(2)Ru(S(2)CNC(4)H(8)NCS(2))Au(PPh(3))](...

A simple protocol was used to prepare amine functionalized cellulose nanocrystals (CNC-NH2). In the first step, epichlorohydrin (EPH) was reacted with ammonium hydroxide to produce 2-hydroxy-3-chloro propylamine (HCPA). In the next step, HCPA was grafted to CNC using the etherification reaction in an organic solution media. Various reaction parameters, such as time, temperature, and reactant mo...
