Researchers of KIT and Evonik Industries Have Developed a Novel Polymer Network that Selfheals Rapidly and Repeatedly at Relatively Low Temperatures Scratches in the car finish or cracks in polymer material: Self-healing materials can repair themselves by restoring their initial molecular structure after the damage. Scientists of the Karlsruhe Institute of Technology and Evonik Industries have developed a chemical crosslinking reaction that ensures good short-term healing properties of...

THE WOODLANDS, Texas, Feb. 28, 2014 /PRNewswire/ -- Independence Oilfield Chemicals, LLC (IOC) has developed a new chemistry specifically designed for ultra-low polymer concentrations as part of their CoFlo(TM) (Cooperative Flow Back) initiative. Within this concept is IOC's VisFlo(TM)-100 crosslinking system (patent pending), the industry's first to combine the advantages of slickwater and guar-based systems in hydraulic fracturing. "We're keenly interested in working with clients...

KIT Researchers Developing a Novel Gel for Biological and Medical Applications A novel method developed by researchers from Karlsruhe Institute of Technology (KIT) and Jacobs University Bremen enables manufacturing of polymer layers with tailor-made properties and multiple functions: A stable porous gel (SURGEL) for biological and medical applications is obtained from a metal-organic framework (SURMOF) grown up on a substrate. The method is presented in the renowned Journal of the American...

When a chair leg breaks or a cell phone shatters, either must be repaired or replaced. But what if these materials could be programmed to regenerate-themselves, replenishing the damaged or missing components, and thereby extend their lifetime and reduce the need for costly repairs? That potential is now possible according to researchers at the University of Pittsburgh Swanson School of Engineering, who have developed computational models to design a new polymer gel that would enable...

Turning lignin, a plant's structural "glue" and a byproduct of the paper and pulp industry, into something considerably more valuable is driving a research effort headed by Amit Naskar of Oak Ridge National Laboratory. In a cover article published in Green Chemistry, the research team describes a process that ultimately transforms the lignin byproduct into a thermoplastic - a polymer that becomes pliable above a specific temperature. Researchers accomplished this by reconstructing larger...

Tough Gel May Help With Replacing Damaged Cartilage In Human Joints

Biocompatible material created at Harvard is much tougher than cartilage A team of experts in mechanics, materials science, and tissue engineering at Harvard have created an extremely stretchy and tough gel that may pave the way to replacing damaged cartilage in human joints. Called a hydrogel, because its main ingredient is water, the new material is a hybrid of two weak gels that combine to create something much stronger. Not only can this new gel stretch to 21 times its original...

Researchers at the University of Massachusetts Amherst have reportedly developed a new method for printing two-dimensional polymer sheets that can be folded into three-dimensional creations by simply adding water. According to university and National Science Foundation (NSF) press releases, Christian Santangelo, Ryan Hayward and their colleagues were inspired by the way a flower petal naturally expands to develop a new techique that harnesses a technique called photolithography, in which a...

Researchers at the Georgia Institute of Technology have designed a multiple-compartment gel capsule that could be used to simultaneously deliver drugs of different types. The researchers used a simple "one-pot" method to prepare the hydrogel capsules, which measure less than one micron. The capsule's structure -- hollow except for polymer chains tethered to the interior of the shell -- provides spatially-segregated compartments that make it a good candidate for multi-drug encapsulation and...

Scientists can now manufacture a synthetic version of the self-healing sticky substance that mussels use to anchor themselves to rocks in pounding ocean surf and surging tidal basins. A patent is pending on the substance, whose potential applications include use as an adhesive or coating for underwater machinery or in biomedical settings as a surgical adhesive or bonding agent for implants. Inspiring the invention were the hair-thin holdfast fibers that mussels secrete to stick against rocks...
