A method to speed up gunshot residue detection and another capable of identifying antipsychotics in the brain are the latest pieces of work of the Metabolomips group of the University of the Basque Country The University of the Basque Country's (UPV/EHU) METABOLOMIPs group develops analytical methods to help characterize different types of substances, and focuses on the forensic sciences, in particular. For example, they have just developed a methodology for detecting gunshot residues...

Researchers at the Public University of Navarre (UPNA) are taking part in a project for the design and manufacture of composite PVC materials based on nanofillings, the aim being to control and optimise the photostability thermal resistance and the permeation of gases of the plastic material. Also involved in the project are the Compuestos y Granzas, S.A. (CYGSA) company and the L´Urederra Technological Centre. The project will last until December 2012. The project is to develop...

Process Makes Polymers Truly Plastic

Just as a chameleon changes its color to blend in with its environment, Duke University engineers have demonstrated for the first time that they can alter the texture of plastics on demand, for example, switching back and forth between a rough surface and a smooth one. By applying specific voltages, the team has also shown that it can achieve this control over large and curved surface areas. "By changing the voltage applied to the polymer, we can alter the surface from bumpy to smooth...

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...

Work inspired by curly leaves Inspired by nature's ability to shape a petal, and building on simple techniques used in photolithography and printing, researchers at the University of Massachusetts Amherst have developed a new tool for manufacturing three-dimensional shapes easily and cheaply, to aid advances in biomedicine, robotics and tunable micro-optics. Ryan Hayward, Christian Santangelo and colleagues describe their new method of halftone gel lithography for photo-patterning...

Squeezing polymers produces chemical energy but raises doubts about implant safety A polymer is a mesh of chains, which slowly break over time due to the pressure from ordinary wear and tear. When a polymer is squeezed, the pressure breaks chemical bonds and produces free radicals: ions with unpaired electrons, full of untapped energy. These molecules are responsible for aging, DNA damage and cancer in the human body. In a new study, Northwestern University scientists turned to squeezed...
