Unprecedented Spin‐Lifetime of Itinerant Electrons in Natural Graphite Crystals

Advanced Functional Materials, EarlyView.
Graphite exhibits extraordinary spintronic potential, with electron spin lifetimes reaching 1,000 ns at room temperature ‐ over 100 times longer than graphene‐based devices. Magnetic resonance spectroscopy reveals strong anisotropy: out‐of‐plane spins live 50 times longer than their in‐plane counterparts.

Radial velocities from the N2K Project: 6 new cold gas giant planets orbiting HD 55696, HD 98736, HD 148164, HD 203473, and HD 211810 [PDF]

, 2018
The N2K planet search program was designed to exploit the planet-metallicity correlation by searching for gas giant planets orbiting metal-rich stars. Here, we present the radial velocity measurements for 378 N2K target stars that were observed with the ...

In Situ Study of Resistive Switching in a Nitride‐Based Memristive Device

Advanced Functional Materials, EarlyView.
In situ TEM biasing experiment demonstrates the volatile I‐V characteristic of MIM lamella device. In situ STEM‐EELS Ti L2/L3 ratio maps provide direct evidence of the oxygen vacancies migrations under positive/negative electrical bias, which is critical for revealing the RS mechanism for the MIM lamella device.

Giant pockmarks discovered on the West Greenland shelf

Arctic, Antarctic, and Alpine Research
Pockmarks provide valuable insights into subsurface fluid dynamics, methane release, and potential geohazards. We present the first detailed mapping and characterization of giant pockmarks (>250 m diameter) on the West Greenland continental shelf using ...

Tectonic features of Gaoshiti-Moxi paleo-uplift and its controls on the formation of a giant gas field, Sichuan Basin, SW China

Petroleum Exploration and Development, 2015
Based on the latest geological, seismic, drilling and outcrop data in the Sichuan Basin, the geological structure and evolution history of Gaoshiti-Moxi paleo-uplift was studied to find out controlling factors of the Sinian-Cambrian Anyue giant gas field.

Terrestrial planet formation in low eccentricity warm-Jupiter systems

, 2009
We examine the effect of giant planet migration on the formation of inner terrestrial planet systems. We consider situations in which the giant planet halts migration at semi-major axes in the range 0.13 - 1.7 AU due to gas disk dispersal. An N-body code

High‐Entropy Perovskite Nanofibers for Bifunctional Air Electrodes in Reversible Protonic Ceramic Electrochemical Cells

Advanced Functional Materials, EarlyView.
High‐entropy perovskite nanofibers serve as robust and active bifunctional air electrodes in reversible protonic ceramic electrochemical cells. Their compositional complexity stabilizes the lattice, enriches oxygen vacancies, and accelerates surface exchange.

The Heavy Element Composition of Disk Instability Planets Can Range From Sub- to Super-Nebular

, 2011
Transit surveys combined with Doppler data have revealed a class of gas giant planets that are massive and highly enriched in heavy elements (e.g., HD149026b, GJ436b, and HAT-P-20b).

Two cases of giant intestinal gas cyst

Journal of British Surgery, 1978
Abstract Large gas cysts of the colon are uncommon and only some 30 cases have been reported (Moss, 1975). They usually arise from the sigmoid colon and are always associated with diverticular disease (Schenken and Cochran, 1972). In view of their rarity, 2 further cases with different presenting factors are discussed.

Multiple Populations of Extrasolar Gas Giants [PDF]

The Astrophysical Journal, 2019
Abstract There are two planetary formation scenarios: core accretion and gravitational disk instability. Based on the fact that gaseous objects are preferentially observed around metal-rich host stars, most extrasolar gaseous objects discovered to date are thought to have been formed by core accretion.
