Flocculation of microfibrillated cellulose in shear flow [PDF]
Cellulose, 2012 AbstractIn this work, the rheological properties of microfibrillated cellulose suspensions under stepped flow and constant shear were studied using a combination of rotational dynamic rheometer and digital imaging. During each rheological measurement, the structure of the suspension was monitored through a transparent outer cylinder with a digital ...

The influence of draw ratio on morphology and thermal properties of MFCs based on PP and PET [PDF]
, 2016 The main goal of this study is to investigate the influence of draw ratio on morphology and properties in microfibrillar composites (MFCs). In situ MFCs based on polypropylene (PP) and poly(ethylene terephthalate) (PET) have been prepared at the weight ...

The structure of the α-keratin microfibril
Bioscience Reports, 1983 Quantitative measurements of the intensity of the meridional reflections in the X-ray-diffraction pattern of α-keratin are shown to be consistent with a microfibril structure in which a surface lattice with an axially projected period around 200 Å is subject to a periodic interruption with an axially projected period of 470 Å. Taken in conjunction with

Journal of Applied Polymer Science, EarlyView.Advanced image analysis of electrospinning jet morphologies. ABSTRACT This study investigates the effects of jet formation and dynamics on fiber morphology during the electrospinning process. Experiments were conducted using virgin PET (v‐PET) and recycled PET (r‐PET) to examine the influence of molecular weight, electric field intensity, polymer ...

Solid-state NMR investigations of cellulose structure and interactions with matrix polysaccharides in plant primary cell walls [PDF]
, 2015 Until recently, the 3D architecture of plant cell walls was poorly understood due to the lack of high-resolution techniques for characterizing the molecular structure, dynamics, and intermolecular interactions of the wall polysaccharides in these ...

Production of Cellulose Microfibrils by Rhizobium [PDF]
Applied Microbiology, 1975 Electron microscope examination of Rhizobium spp. revealed microfibrils produced by flocculating strains but not by nonflocculating strains. The microfibrils from R. trifolii (NA30) were isolated and identified as cellulose by enzymatic, X-ray diffraction, and infrared spectral analyses. Both

Biofuels, Bioproducts and Biorefining, EarlyView.Abstract Agroindustrial activity generates substantial waste during harvesting and processing. This study investigated the potential use of sugarcane bagasse, corn cob husk, and wheat bran as substrates for enzyme production by Aspergillus niger and Ceriporiopsis subvermispora. Aspergillus niger and C. subvermispora exhibited comparable filter paperase

PEK14: A Kinesin‐4 Necessary for Male‐Derived Fertility in Arabidopsis thaliana
Cytoskeleton, EarlyView.ABSTRACT Of the 61 kinesins annotated in Arabidopsis thaliana, many are still without assigned function. Here, we have screened an insertional mutant library of Arabidopsis pollen‐expressed kinesins for fertility defects. Insertional mutants for three kinesins showed a significant reduction in seed set.
