Nanofibrillated cellulose composite hydrogel for the replacement of the nucleus pulposus

Dominique Pioletti, Pierre-Etienne Bourban, Ana Borges de Couraça, Fabien Duc

The swelling and compressive mechanical behavior as well as the morphology and biocompatibility of composite hydrogels based on Tween® 20 trimethacrylate (T3), N-vinyl-2-pyrrolidone (NVP) and nanofibrillated cellulose (NFC) were assessed in the present stu ...

Coated medical device and method of coating a medical device to reduce, fibrosis and capsule formation

Hicham Majd, Boris Hinz, Giorgio Pietramaggiori

Coating for a medical device comprising cell-adhesive proteins having the ability to reduce fibrous reaction, said coating being in the form of separate islets having an individual area which is less than 12 [mu]m2 and wherein the distance between the isle ...

In vivo study of an injectable poly(acrylonitrile)-based hydrogel paste as a bulking agent for the treatment of urinary incontinence

Peter Frey, Jeffrey Alan Hubbell, Lionel Ambroise Micol

Urinary incontinence can be treated by endoscopic injection of bulking agents, however, no optimal therapeutic effect has been achieved upon this treatment yet. In the present study, the development of a injectable poly(acrylonitrile) hydrogel paste is des ...

Enhanced Electron Collection Efficiency in Dye-Sensitized Solar Cells Based on Nanostructured TiO2 Hollow Fibers

Michael Graetzel, Shaik Mohammed Zakeeruddin, Jacques-Edouard Moser, Elham Ghadiri

Nanostructured TiO2 hollow fibers have been prepared using natural cellulose fibers as a template. This cheap and easily processed material was used to produce highly porous photoanodes incorporated in dye-sensitized solar cells and exhibited remarkably en ...

Quantitative distribution patterns of additives in self-leveling flooring compounds (underlayments) as function of application, formulation and climatic conditions

Karen Scrivener

The distributions of organic additives in self-leveling flooring compounds (SLCs) were investigated using laser-scanning microscopy for the selective visualization of the additives, which had been previously stained by a fluorescent dye. The distributions ...

Self-cleaning modified TiO2-cotton pretreated by UVC-light (185 nm) and RF-plasma in vacuum and also under atmospheric pressure

César Pulgarin, Juan Kiwi

Two new innovative findings presented in this study are: (a) TiO2-cotton fabrics obtained by pretreatment with UVC-light (185nm) at atmospheric pressure introduced functionalities into the cotton surface enabling the chelation/binding of TiO2. This was pos ...

Parameter and process significance in mechanistic modeling of cellulose hydrolysis

David Andrew Barry

A process-based model relevant to landfill and anaerobic digesters was developed, which included a novel approach to biomass transfer between a cellulose-bound biofilm and biomass in the bulk liquid. Model results highlighted the significance of the bacter ...

Photocatalytic Discoloration of Organic Compounds on Outdoor Building Cement Panels Modified by Photoactive Coatings

César Pulgarin, Victor Sarria

Cement based Eternit plates modified by TiO2/SiO2 surface layers acquired self-cleaning properties. The TiO2/SiO2 coating was transparent indicating that the small TiO2 (rutile) crystals cause no significant scattering. The parameters related to the compos ...

Sensor technologies based on a cellulose supported platform

Mohammad Khaja Nazeeruddin

A simple approach to sensor development based on encapsulating a probe molecule in a cellulose support followed by regeneration from an ionic liquid solution is demonstrated here by the codissolution of cellulose and 1-(2-pyridylazo)-2- naphthol in 1-butyl ...

One-Step Conversion of Cellobiose to C6-Alcohols Using a Ruthenium Nanocluster Catalyst

Paul Joseph Dyson, Cheng Zhao, Ning Yan, Huizhen Liu

The one-step conversion of cellulose to C6-alcs. via green and energy efficient approaches has, as far as we are aware, not been reported. Such a process presents a considerable challenge, the two key problems being (1) finding a suitable solvent that diss ...
