Some examples are conducting polymers, such as polypyrrole 13 or poly(3,4-ethylenedioxythiophene) (PEDOT); 14 radical polymers; 13 organosulphur derivatives 15,16 and polymers with carbonyl groups. 10,17 Polyimides were chosen in this work due to their
Our metal nanoparticle-free approach to encapsulating cyt. c in aerogels is advantageous because it is a simple procedure that may lead to the development of a more generally applicable protocol for encapsulating other proteins as well. Many proteins may not
2016/6/1· Indium Corporation Tech Paper Authored by: Ed Briggs and Ronald C. Lasky, PhD, PE. Abstract The continuing miniaturization of personal electronics devices, such as mobile phones, personal music devices, and personal computing devices has driven the need for increasingly smaller active and passive electrical components. Not too long ago, 0402 (40 x 20mils) passives were […]
We show that alkaline earth metal oxides, in our case MgO nanocrystals, exhibit stable photoalytic activity for CO/CO2-free H2 production from liquid methanol at room temperature. The performance of MgO nanocrystals toward methanol dehydrogenation increases with time and approaches ~320 μmol g−1 hour−1 after a 2-day photoalytic reaction.

A dielectric layer containing a hafnium tantalum oxide film and a method of fabriing such a dielectric layer produce a dielectric layer for use in a variety of electronic devices. Eodiments include structures for capacitors, transistors, memory devices, and
Oxides of the three materials can be deposited by sputtering the metal. Some oxide compounds, and all fluoride compounds, melt before reaching evaporation temperature; others, such as silica, alumina and refractory oxide compounds (hafnia and zirconia), evaporate from …
Examples of endoskarn veins and massive endoskarns at the Empire mine, Idaho (A-E) and the Antamina mine, Peru (F-H). A. Garnet + pyroxene endoskarn veins in granite porphyry; feldspar phenocrysts still can be clearly seen. B. DDH 6-274.5’, scapolite (Me 18–25 ) veins and garnet-dominant veins in granite porphyry; scapolite veins are earlier than the garnet-dominant veins.

This will be followed by a few examples demonstrating the appliion of this technique. Inorganic chemical reactions, such as the conversion of titanocene dichloride to its dimeric form and the final Ti(III) metallocene, are highly sensitive to oxygen, and therefore must be carried out in air-free conditions.
Investigations in the now-submerged cave systems on the Yuán Peninsula continue to yield evidence for human presence during the Pleistocene-Holocene transition. Skeletal remains are stered throughout the caves of Quintana Roo, most representing individuals who died in situ. The reasons why they explored these underground environments have remained unclear. Here, we announce the

We present evidence that a rock sample found in the Koryak Mountains in Russia and containing icosahedrite, an icosahedral quasicrystalline phase with composition Al63Cu24Fe13, is part of a meteorite, likely formed in the early solar system about 4.5 Gya. The quasicrystal grains are intergrown with diopside, forsterite, stishovite, and additional metallic phases [khatyrkite (CuAl2), cupalite
Metal complexes based on 1,3-dithiole-2-thione-4,5-dithiolate (dmit) ligand have been intensively studied for more than 40 years due to their unusual chemical and physical properties.

For example, sodium is a group 1 metal, and like all group 1 metals, it has one valence electron. This electron is not held very tightly by the atom and is easily lost, which forms the Na1+ ion.
