The article reports on the findings of a research team, which include Adriano M. Conte of the University of Rome, that ancient paper discoloration is caused by cellulose oxidation.
The article discusses a research study about the fabrication of ultrathin rechargeable lithium-ion batteries on a single sheet of paper that resulted in highly flexible and lightweight portable power sources, with reference to a study published in a previous issue of the journal "ACS Nano."
The article focuses on the optically transparent paper made from nanosized cellulose fibers by Masaya Nogi and colleagues. The researchers made nanofiber paper with cellulose, of which its differences in the size and width of the fiber of internal cavities give the papers different physical properties. Derek G. Gray, a professor, said that the new method devised by Nogi's group is a practical route to novel materials on a key renewable resource.
The article highlights the results of a study by Victor L. Pushparaj and colleagues on the creation of nanocomposite paper that functions as a thin, lightweight, flexible energy-storage device. According to Pushparaj and colleagues, the paper can be rolled up, twisted or bent to any curvature and is completely recoverable. They note that the discharge capacity and performance they observe compare well with data reported for other flexible energy storage devices.
The article offers insights into the science behind sandpaper, technically referred to as a coated abrasive. According to the author, researchers must consider the chemical properties of the abrasive material and the adhesive to design sandpaper. She adds producing effective sandpaper involves matching a good abrasive with a good adhesive. She also mentions some factors affecting the abrasive's performance and the materials used to help reduce friction.
The article comments on issues related to the chemical industry compiled as of January 2007. Xerox Corp. and Palo Alto Research Center Inc. have developed "erasable paper," a paper that erases the content of its pages within 16 to 24 hours of initial printing or by immediately running the paper through the printer again. One reader said that his son requested for the "C&EN" during his toilet training.
The article focuses on the research by Eva Malmstrom and coworkers at Royal Institute of Technology, which shows that filter paper can be turned into a water-resistant cleaning material. The team employed a process known as atom transfer radical polymerization to graft the fiber surfaces with a superhydrophobic fluorinated polymer layer.
Reports on the food prepared by the Moto restaurant in Chicago. Idea of chef Homaru Cantu to print images of food on edible paper made from soybeans and cornstarch with organic flavoring using of a Cannon printer; Offer by Cantu of ten courses included in two or more paper items.
Reports on a study by Cornell University associate professor Z. Jane Wang and her graduate student Umberto Pesavento titled "Falling Paper: Navier-Stokes Solutions, Model of Fluid Forces and Center of Mass Elevation". Reasons why leaves and paper fall and rise in a seeming chaotic manner; Failure of the classic aerodynamic theory to predict the trajectory of thin, flat things.
