In this study, in situ synthesis of polyvinyl alcohol (PVA)/nano-hydroxyapatite (n-HA)/cellulose nanocrystals (CNC) organic-inorganic biocomposite porous scaffolds is reported. The effect of the CNC content on the properties of the biocomposite scaffold was investigated and characterized using field-emission scanning electron microscopy, Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) analysis, porosity and compressive strength measurements, thermal studies, and in vitro biomineralization and degradation studies. The morphological study showed highly porous structures with good pore interconnectivity in which n-HA was homogeneously dispersed. XRD analysis showed a decrease in the crystalline fraction and crystallite size of nano-hydroxyapatite with introduction of PVA and with increasing content of CNC. It was observed that the porosity decreased to some extent with increasing CNC content, while increases in the compressive strength (from 0.85 to 2.09 MPa) and elastic modulus (from 4.68 to 16.01 MPa) were found as the CNC content was increased. In vitro biomineralization study revealed the formation of apatite on PVA/n-HA/CNC biocomposite scaffolds when soaked for 7 and 14 days in simulated body fluid (SBF) solution. The obtained porous scaffolds offering good mechanical performance may provide a promising alternative scaffolding matrix for use in the field of bone tissue engineering. © 2014 Springer Science+Business Media Dordrecht.

Mineral fillers are added during papermaking to improve the optical and printing properties of paper and decrease energy costs. Filler loading using conventional approaches has some disadvantages, such as reduction in paper strength. The finer filler, the more the strength loss. Several methods and materials have been reported to overcome or alleviate the same, but with higher costs. Our approach provides an economically viable solution to the problem, using conventional papermaking materials. Talc filler of different particle sizes, preflocculated using different doses of cooked amphoteric starch, were used for papermaking. Relatively higher filler retention, paper strength, and hydrophobicity of paper were obtained with preflocculated talc compared to native talc. The optical properties of paper were unchanged on the loading of similar talc after preflocculation. The preflocculated talc of finer particle size provided higher opacity at similar ash, as well as paper strength, than the native talc of coarser size. Source

In order to improve the functional compatibility and mechanical performance of biocomposite scaffolds, two different biocomposite scaffolds based on ovalbumin (OVA)/polyvinyl alcohol (PVA) reinforced with unmodified and aminated cellulose nanocrystals (CNCs) cross-linked with glutaraldehyde (GA) were fabricated by a freeze drying process. It was observed that the microstructure and mechanical properties of the biocomposite scaffolds were not affected to a great extent by the presence of aminated CNCs. At a compressive strain of 70%, the compressive strengths of PVA/OVA (porosity: ∼85%) (a), PVA-CNCs/OVA (porosity: ∼87.4%) (b), and PVA-CNCs-NH2/OVA (porosity: ∼87.7%) (c) were 0.08 MPa, 0.21 MPa and 0.26 MPa, respectively. © 2014 Elsevier B.V.

« China researchers optimize parameters for direct bacterial production of H2 from raw corn stalk without substrate pretreatment | Main | Chempolis partners with Avantha Group on cellulosic ethanol in India » Earlier this month, Audi began testing driverless transport systems (DTS) at its Ingolstadt plant. With DTS, logistics employees no longer have to fetch the required goods from the material shelves; the goods will come to them fully automatically. Audi says it is the first automobile manufacturer to implement such a DTS-based goods-to-person concept. Driverless transport systems drive under the shelves, lift them up and transport them automatically to a central picking station. There, symbols on a monitor show the employees which goods they have to put into which place. Unlike the previous person‑to‑goods commissioning, a DTS does not need wide lanes and picking bays, so the shelves can be positioned much closer together. That reduces space requirements by 25%. A fleet-management system coordinates the carries so that they always arrive at the commissioners’ workplaces punctually. Employees never have to wait for their goods—a shelf change at the picking station takes just four seconds. The robots receive the order to bring a shelf for commissioning by Wi‑Fi. When in motion, they orient themselves by means of QR codes on the floor, which are read by a camera installed under the DTS. The autonomous transport systems move in a separate area from where the employees work. The goods‑to‑person principle eliminates not only long working times in the picking bays, but also long walking distances and the pushing of heavily loaded material carts. If components change or new ones are added, this can be quickly integrated. The autonomous transport systems are equipped with eight rechargeable batteries with a running time of approximately seven hours. When their charge status has fallen to 40%, they automatically return to their charging stations. There, they are recharged for two hours via induction plates in the floor, and then automatically return to work in the transporting shelves. When charged, the robots accelerate to a speed of 3.6 km/h (2.2 mph), irrespective of the weight of the material carried. They can transport a maximum of 600 kilograms. The commissioning of the owner’s manuals for the Audi A3 models is the first task for which the new supermarket concept is being tested. Next year, additional commissioning stations at Audi will take over the goods‑to‑person principle.

Fair amount of poaching going on in the online media industry these days, indicative of activity in the market: now Reuters Group has appointed Dean Wright, the editor-in-chief of MSNBC.com, to head its digital media business. He will take up the new post of senior VP and managing editor for consumer services in New York, where he will lead the editorial operations and programming for the company’s consumer media services, including the online, mobile, and interactive television platforms. As we have been documenting here, this further moved Reuters into consumer space. Read our interview recently with Chris Ahearn, president of Reuters Media, for some insight into the thinking…Some more details here… For MSNBC.com, this is a big blow. Earlier this year, MSNBC.com deputy editor Michael Silberman left for Rodale. Some of these editorial moves could be driven by the continuing uncertainty about MSNBC.com’s status as rumors of Microsoft pulling out of the parent TV channel abound.
