Nano Crystaline Magnetic Materials

We are currently in the process of finding magnetic properties of iron and nickel samples for their use and application in small-scale electronic and magnetic storage devices. I have presented posters on my findings in postern form which I carried at Cornell University and on the Methodology of Elemental Analysis Lab in Food and Drug Administration (Arsenic in rice speciation) at the Undergraduate Research Day at Queensborough Community College.

The Lithium Nickel Manganese oxide battery is still in its experimental stages. It consists of a 25% nickel substituted in a LiMn2O4 spinel. This is because Manganese will have 4 electrons in its valence shell which will avoid the Jahn-Teller distortion caused due to the Mn3+. Due to the oxidation or reduction of Nickel ions which leads to the transfer of electrons which corresponds to electric current. LiNi0.5Mn1.5O4 takes shape in two conceivable crystallographic structures concurring the cationic sub lattice: the face-focused spinel (S.G. Fd3m) named as "cluttered spinel" furthermore, the straightforward cubic stage (S.G. P4332) named as "requested spinel". This addition allows

On August 12, 2015, I received a request by P.I.O. Crystal Nosal for a photo of Alysha Howard. A request was received by Chris Teale for a photo. I saw Ms. Nosal who told me she had deferred Mr. Teale to NECMEC. There have been no leads received from the NECMEC bill board campaign as of this date.

The crystal merchant does not fulfill his religious dharma. During his stay at the merchant’s store they had talked about dreams and goals they had. The merchant lived his life through the Koran. He believed that he had to follow the five obligations: To believe only in one true God, pray five time days, fast during Ramadan, be charitable to the poor, and to once in his life, to visit the holy city of Mecca. He fulfills four out of the five obligations, to visit the holy city of Mecca was the only obligation that he did not want to do.

All minerals have a crystal structure.A mineral is a naturally occurring, Inorganic, Solid, with a unique chemical composition, and a crystalline structure. (Class Notes 11/03/15). The minerals form when the magma starts to cool inside of crust, they started to cool in the water and water start to evaporate ,the liquid cool and mineral get a solid form.Citation (Video-How the Earth Made Us episode 1:deep earth). The Crystal that were made in lab weren’t not because they formed by using man made formula. The August Birthstone was a minerals because birthstone by geologic processes in rocks in their natural environment.(http://www.burkemuseum.org/geology/birthstones/)The

Using of spinel ferrites nanoparticles in electromagnetic devices such as memories, sensors and data storage in modern information technology applications [1-3] made many researchers all over the world do all efforts for synthesis and development of magnetic nano-particles. These nano-particles possess special magnetic and electrical properties with high

In art class we are learning the proper techniques to draw and color. For this reason and many others the 5th graders at Charleston Middle School should take a field trip to Crystal Bridges because it has an amazing atmosphere, beautiful art, and important history.

Crystalloids are a type of fluid and electrolytes therapy. They are water and salt solution that is made up of small molecules that may be dextrose or non-dextrose. The small molecules make it easier for its solution to transfer from the blood into the cells and body tissue and may increase the fluid volume in both interstitial and intravascular spaces. A crystalloids solution can be hypotonic, hypertonic or isotonic.

MRI have becoming increasingly popular methods of medical imaging over the years. Compared to X-ray, ultrasound or computed tomography (CT) scan, MRI provides more information about the structures in the body and it is considered to be safer. Using contrast material during MRI scan can show certain structures more clearly, and increase the odd of detecting abnormal tissues [1]. Superparamagnetic iron oxide (SPIO) particles are currently the most preferred material [2]. These superparamagnetic agents are extremely strong enhancers of proton relaxation and have been the subject of extensive research over the past decade [3]. Applications of SPIO have ranged from detecting inflammatory

Common magnets found in offices and homes pose little threat, but magnets that are made out of neodymium-iron-boron (NdFeB) might interfere with cardiac devices and pose possible harm to patients. NdFeB magnets are being used more often in office and home products, as well as jewelry, clothes and toys.

Romanenko et al. identified a correlation between large LAM values and the “hot” regions of cavities [10, 11]. The temperature increase from local heating increases the fraction of normally conducting electrons, so any potential sources for the heating need to be minimized. A proposed explanation for the local heating is that dislocations vibrate with passing phonons and disperse them, thus slow down thermal conduction [4]. Dislocations can also affect cavity performance if they pin magnetic flux centers, resulting in irreversibility of magnetization curves [5]. These adverse effects of dislocations necessitate a heat treatment for recovery or recrystallization after deep drawing.

The magnetic properties of compounds 1 – 4 were measured on polycrystalline samples dispersed in eicosane. The phase purity of the samples was demonstrated by powder X-ray diffraction (see Figures S9 – S12 in the SI). Fig. 5 shows the temperature dependence of χMT for 1 – 4. The values of χMT at 280 K are 12.1; 15.1; 18.6; 18.3 cm3 mol−1 K (1; 2; 3; 4), consistent with four uncoupled Mn(III) ions (S = 2, g = 2, χMTcalc = 12.0 cm3 mol−1 K) and four uncoupled Ln(III) ions. On lowering the temperature to 50 K, 2 – 4 predominately show a decrease in χMT, which is most likely caused by the depopulation of the

Ferro-electrics are an important class of materials which posses excellent electro-mechanical coupling behavior \cite{jayendiran2012modeling}. These materials have been used in sensors, actuators, biomedical and naval applications for several years. These materials behave linearly under low electric fields and mechanical stresses, but show nonlinearity at higher electric fields and mechanical stresses; see the review articles \cite{kamlah2001ferroelectric,landis2004non,huber2005micromechanical}.

The term dielectric resonator (DR) first appeared by Ritchmyer [19], when he showed that unmetallized dielectric objects in the form of toroids could function as microwave resonators. However, his theoretical investigations failed to generate significant interest and practically nothing happened in this area for over 25 years. In the early 1960s, researchers from Columbia University, Okaya and Barash [34-35] reported the first ever DR in the form of a single crystal TiO2. In the mid-1960s, Cohn [36] performed extensive theoretical and experimental evaluation of DR. Nevertheless, the DR was still far from being used in practical applications. A real breakthrough in the dielectric ceramic industry occurred in the early 1970s when researchers

Permanent magnet motor was built by a permanent magnet excitation magnetic field to achieve electromechanical energy conversion device, which is electrically excited synchronous motor as a synchronous rotation speed, also known as permanent magnet synchronous motors. Magnet synchronous motor, particularly rare earth permanent magnet synchronous motor compared with the electrical excitation synchronous motor, with a compact, small size, light weight and other characteristics, and the size and structure of the permanent magnet motor in the form of flexible, it can be a variety of topological structures form. As the permanent magnet electrical motor canceled the excitation system, thereby improving the efficiency of the motor so that the
