Seshadri Ramkumar, an associate professor of nonwoven technologies, said the Texas Tech-created nonwoven cotton absorbent wipe with activated carbon core makes it a perfect remediation tool for use by cleaning crews trying to remove the toxic material.
Not only did it clean up the rust-colored crude oil, but also it adsorbed toxic polycyclic aromatic hydrocarbon vapors reportedly sickening oil spill clean-up crew members.
“It definitely has proven itself a perfect product for cleaning up the oil spill,” Ramkumar said. “This preliminary test in Louisiana has shown that our wipe material is unique from others in that it easily absorbs liquids, and it has vapor-holding capacity. This will help workers clean beaches and stay safe at the same time.”
Ramkumar said his latest research shows raw cotton-carbon Fibertect® can absorb oil up to 15 times its weight. Unlike synthetic materials like polypropylene that are currently used in many oil containment booms, Fibertect® is made from environmentally friendly raw cotton and carbon.
Amit Kapoor is president of First Line Technology, which distributes Fibertect® commercially. Though the product has been tested in the lab with raw crude and motor oil, he said the company wanted to field-test the product.
Earlier this week, he sent a sales representative, who also works as an independent contractor for BP, to one of the worst-hit areas.
“We wanted to test the effectiveness of Fibertect® on the crude oil for beach cleanup,” Kapoor said. “Fibertect® was taken to the empty beaches of Grand Isle, and then laid out on top of a blob of oil that had settled on the beach. It worked very well in absorbing and containing the oil. The glob stuck to the Fibertect® and did not release from the material.”
Though Kapoor said he had seen Fibertect® pick up similar material with a pasty consistency, such as petroleum jelly, the results shocked the sales representative sent to run the experiment.
“Our representative was shocked because he hadn’t seen a product work like that with the speed or the effectiveness,” Kapoor said. “He showed many other contractors that were working on the beach and they were impressed as well.”
Fibertect® was approved for use as a sorbent by the U.S. Environmental Protection Agency, Ramkumar said. The product already has proven that it can also adsorb toxic fumes associated with chemical remediation, he said. Evaluation by Lawrence Livermore National Laboratory found that it can retain offgassing mustard vapors efficiently and does not shed loose particles.
Originally developed to protect the U.S. military from chemical and biological warfare agents, Fibertect® contains a fibrous activated carbon center that is sandwiched between layers.
The top and bottom layers, made from raw cotton, can absorb oil while the center layer holds volatile compounds such as the polycyclic aromatic hydrocarbons, or blistering agents such as mustard vapors or other toxic chemicals.
“Fibertect® already has proven to be effective in the bulk decontamination of chemical warfare agents and toxic industrial chemicals, but our proposal here is to use it to aid in the clean-up efforts in the Gulf,” Kapoor said. “Fibertect® allows for a green, environmentally safe, biodegradable technology that is perfect for the expanding effort to protect and decontaminate coastal lands and wildlife. We welcome the opportunity to work with the government, BP or anyone else in a joint effort to defend and preserve our planet.”

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.
Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...

The quality of materials often depends on the manufacturing process. In casting and welding, for example, the rate at which melts solidify and the resulting microstructure of the alloy is important. With metallic foams as well, it depends on exactly how the foaming process takes place. To understand these processes fully requires fast sensing capability. The fastest 3D tomographic images to date have now been achieved at the BESSY II X-ray source operated by the Helmholtz-Zentrum Berlin.
Dr. Francisco Garcia-Moreno and his team have designed a turntable that rotates ultra-stably about its axis at a constant rotational speed. This really depends...
