New Type of Battery: Invented Biocompatible

Scientists have invented a completely new type of biocompatible battery that produces the same type of electrical energy based on ions as humans and other living things. In our bodies, the ions that flow sodium, potassium and other electrolytes are the electrical signals that feed the brain and control the heart's rhythm, the movement of muscles and more. In traditional batteries, electrical energy, or current, flows in the form of mobile electrons. This electron stream outside the battery is generated inside the battery by moving the positive ions from one end of the electrode from one battery to the other. The battery developed by researchers at the University of Maryland in the United States does the opposite. It moves electrons around in the device to deliver energy that is a flow of ions. This is the first time that has invented a battery that generates ionic current, the researchers. My intention is for ionic systems to interfere with human systems, Liangbing Hu, a professor at the University of Maryland. So came the reverse design of a battery. In a typical battery, the electrons flow through the wires to connect the electronics, and the ions flow through the battery separator. In reverse design, a traditional battery is cut electronically which means that the electrons are flowing through the metal wires. Then the ions have to flow through the outer ionic wires. In this case, the ions in the ionic cable here, the grass fibers can interact with living systems. News courtesy of Science and More.

Researchers Develop See-Through Wood That Looks Just Like Glass

A study published this month describes the way in which a team from the University of Maryland, College Park, has been able to make a piece of wood almost completely transparent. We all know what objects made out of wood look like, right? Well, that may be changing.  A study published this month describes the way in which a team from the University of Maryland has been able to make a piece of wood almost completely transparent.  As the New York Times reports, there are two-phases to the transformation: the first is to treat the wood to remove the color molecule called lignan; the second is to fill the remaining cell structures with the strengthening agent epoxy.  As the research notes, the resulting wood composite is “highly transparent with a total transmittance up to 90%...”  A similar project was undertaken in Sweden, but that scientist was only able to achieve a see-through rate of 85 percent.  Potential applications for the new material include auto manufacturing and building construction, among others.  The team is currently trying to produce larger pieces at a time, as the current size limit is five-by-five inch blocks.

Scientists Find Ways to Use Wood in Electronic Devices

Wood is usually not associated with water filters, even less with electronic devices. But scientists at the University of Maryland say we have not yet discovered all the possibilities of this cheap, natural and sustainable material. VOA's George Putic reports.
