Justin Taylor Mrs.Lewis Tungsten Title of Your Report Tungsten, also known as wolfram, is a chemical element with symbol W and atomic number 74. The word tungsten comes from the Swedish language tung sten, which directly translates to heavy stone. Its name in Swedish is volfram, however, in order to distinguish it from scheelite, which in Swedish is alternatively named tungsten. A hard, rare metal under standard conditions when uncombined, tungsten is found naturally on Earth only in chemical

Conductive polymers are a specific section under the broad range of polymers, that have the ability to effectively conduct electricity. They were discovered by accident in a lab by Hideki Shirakawa in 1974, yet their potential applications were not understood until early 2000s. They are made by doping with n-type and p-type which forces electrons to move throughout the material which normally would not happen because of a polymer molecular structure. They provide many advantages over metals because

cells made of yttria-stablized zirconia (YSZ) electrolyte, the conventional cathode composite is a mixture of YSZ and Sr-doped LaMnO3 (LSM). 1,2 The commonly used YSZ electrolyte oxide in the electrode is to enhance the ionic conductivity, thus increasing the electrochemically active region in the electrode. 1-4

well as enhancing the connection between the electrode and the YSZ electrolyte. YSZ in the electrode also helps match the thermal expansion of the electrode to the electrolyte.1-4 The functions of LSM in the composite cathode include providing electronic conductivity and catalytic activity, but with negligible contributions to ionic conductivity.4,5 The conventional method for fabricating the electrode is to deposit and sinter a mixture of the electrode composites onto a dense YSZ electrolyte.4 The

The “first true battery” was invented by Alessandro Volta, an Italian physicist, in 1800. Batteries are a mass of one or more cells whose chemical reactions create a flow of electrons in a circuit. Batteries contain three basic parts: electrodes, an electrolyte, and a

Do you have the need like most people to protect yourself? Getting a license to buy and carry a deadly weapon such as a gun is ok with some people, but there are many people who are uncomfortable doing so. A nonlethal weapon is a preferred alternative for these people. A stun gun is regarded self-defense tool that is non-lethal and operates by interrupting the connections between the brain and the muscles in the body. Voluntary muscle movement is disrupted by overloading the neurological impulses

Naphazoline Using Silver Polymer In this study, polymer of [AgL]n was immobilized onto the surface of a glassy carbon electrode (GCE), which leads to the efficient electrocatalytic oxidation of Dibucaine and Naphazoline. The GCE was previously tested in PBS buffer (pH = 3) before polymer were drop coated on it. It presented no redox process in the potential range applied. The working electrode coated with polymer of [AgL]n was immersed in the electrolyte solution for 20 min prior to the measurement to ensure

these next generation devices. One of the main areas of research and development of high performance flexible LIBs is the active and inactive materials used in manufacturing these batteries. Active materials are those materials used in the battery electrodes that can store lithium ions in their structure. The remaining materials used in manufacturing flexible

Navigation of blood vessels is an essential part in reaching a lesion or a vessel segment for treatment. Such task is achieved using an endovascular device. The circulatory system being tortuous, improvements to endovascular devices are being investigated. Here the process involved in improving this medical field was by combining two technologies together: endovascular devices and ionic electroactive polymers (i-EAP). Medical procedures such as angioplasty, coronary and peripheral, atherectomy

It is difficult to compare accurately burn times/lighting durations between different manufactures hands-free lighting products since each manufacturer’s reference figures that show their product offering to have an advantage over competitive products. Some manufacturers state statistics of burn time calculated to times long after the emitted light output is useful (down to the last photon). Petzl clearly states it operates a policy whereby it ceases to consider a light effective when the lighting
