Encapsulating Cytochrome c in Silica Aerogel …

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

Process Guidelines to Ensure Optimal SMT Electronics …

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 […]

Room temperature stable COx-free H2 production from …

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.

Synthesis Of A Ti(III) Metallocene Using Schlenk Line …

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.

Paleoindian ochre mines in the submerged caves of the …

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

Evidence for the extraterrestrial origin of a natural …

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
