    LOS ANGELES Authentic J. D. Martinez Jersey , Oct. 28 (Xinhua) -- A team of researchers in the United States has shown it is possible to improve conductivity and safety in lithium-ion batteries, which are used to power many electronic devices around the world, including laptops, iPods, satellites Authentic Ian Kinsler Jersey , artificial hearts and cell phones.

    The work, by researchers from Virginia Commonwealth University, was detailed in a study published recently in the Proceedings of the National Academy of Sciences.

    "Theoretically, you can have your cake and eat it too, when it comes to the stability and conductivity Authentic Francisco Rodriguez Jersey ," Puru Jena, a distinguished professor in the Department of Physics in the College of Humanities and Sciences, was quoted as saying in a news release.

    Instability in lithium-ion batteries due to liquid-state electrolytes that help carry charges from one battery electrode to another is one hazard scientists can prevent, researchers say.

    Despite this instability, compared to more stable solid-state electrolytes Authentic Denny Mclain Jersey , liquid-state electrolytes are commonplace in lithium-ion batteries due to their conductive superiority.

    However, the new theoretical studies has shown it is possible to design solid-state electrolytes not only to be as conductive as their liquid counterparts but also very stable.

    Electrolytes, which are central to a battery, are salts composed of positive and negative ions. Positive ions are atoms that have more protons than electrons, while negative ions inversely have more electrons than protons.

    In a lithium-ion battery Authentic Daniel Norris Jersey , positive lithium ions flow between electrodes via electrolytes. Lithium ions can flow freely through liquid-state electrolytes but are less mobile in a solid-state electrolyte, which adversely affects conductivity.

    To improve the conductivity in solid-state electrolytes, the researchers produced a computational model in which a single negative ion is removed. Negative cluster ions, groups of atoms with more electrons than protons, replace the absent ion.

    Originally Authentic Cameron Maybin Jersey , the electrolyte, which belongs to a family of crystals called antiperovskites, contained positive ions made of three lithium atoms and one oxygen atom. The positive ions were joined with a single chlorine atom that was a negative ion.

    In the computational model, the chlorine atom was replaced by a negative cluster ion created by one boron atom and four fluorine atoms joined to the existing positive ions. Other combinations of negative cluster ions were identified to potentially enhance conductivity.

    "Replacing the chlorine ion with cluster ions improves conductivity because these ions are larger and allow the lithium ions to move quickly, as if they were in a liquid Authentic Anthony Gose Jersey ," said Hong Fang, a postdoctoral fellow in the Department of Physics.

    Next, researchers are now in search of collaborators to test their computational model in a laboratory setting for eventual lithium-ion battery applications.

    The face mask is the most significant protective gear in playing the sport of paintball. It mainly shields the eyes from balls with a traveling speed of up to three hundred ?feet per second?. Most completely cover the face and the ears, but there are those who prefer to wear goggles, protecting only the eyes.

    Paintball masks are designed to absorb any direct shot Authentic Anibal Sanchez Jersey , from any distance or range. An ordinary pair of goggles will supply only a false sense of security and put one at great risk since it they are not constructed to block a paintball. All paintball mask manufactures measure up to DOT safety criteria and safety standards.

    The choice of the mask?s material is of significance. There are masks made of different material from rubber, plastic to foam. It is a wise idea to buy your own face mask rather then renting one. It should be the first equipment purchased before playing paintball. Be sure to properly test the fit of the mask to your face and make sure that you can see clearly so you can well and enjoy your game. The lens is the mask?s most significant quality, so check it carefully; then examine the foam and see if it is comfortable to wear and the design is attractive

    1. Typically, paintball masks will have either non-thermal or thermal lens or be anti-fog for fog resistance: these do not need an anti for agent applied to the lens to perform their function. These thermal lenses will cost more but they are a good choice because they just won?t fog up.

    2. The foam in a paint ball mask is an important factor to consider, as it can determine your level of comfort. For instance Authentic Alex Avila Jersey , a ?Vforce Armor? is a neoprene type of foam ? a type of foam that is considered a good foam, but it is uncomfortable. The ?Vforce Shield? and ?Vforce Profiler? is and open cell and two layer foam which is very comfortable to wear. The open cell foam can be compared to a memory foam that is used in pillows.

    3. Style is another factor. There are masks that are more expensive even when the foam and lens are the same quality as cheaper models, but the difference is in the style of the mask.

    Choose wisely and never sacrifice cost over quality; your safety should always come first!
