Why intracontinental basins subside longer: 3‐D feedback effects of lithospheric cooling and sedimentation on the flexural strength of the lithosphere
Authors: Cacace M. , Scheck‐Wenderoth M.
Published: April 2016

The aim of this study is to reevaluate the character and evolution of the large‐scale subsidence of intracontinental basins using 3‐D thermomechanical numerical simulations accounting for the coupling between sedimentation, rheology‐dependent lithospheric flexure, and thermal contraction by lithospheric cooling. The flexural rigidity of the lithospheric plate is controlled by elastic‐brittle‐plastic rheology, enabling the computation of thermal and mechanical feedback processes occurring during basin subsidence. Numerical results show that depending on the sediment loading history, a rheological stratified lithosphere can subside over geological time scales without imposition of ad hoc geometric and kinematic initial conditions. Three‐dimensional feedback effects of sedimentation on the thermomechanical structure of the plate result in a weakened lower crust mechanically decoupled from the underlying mantle and therefore easily reactivated even under low background stresses. Our results explain the first‐order characteristics of the subsidence in intracontinental basins and reconcile basic observations of their deformation history.
Sea level driven marsh expansion in a coupled model of marsh erosion and migration
Authors: Kirwan Matthew L. , Walters David C. , Reay William G. , Carr Joel A.
Published: April 2016

Coastal wetlands are among the most valuable ecosystems on Earth, where ecosystem services such as flood protection depend nonlinearly on wetland size and are threatened by sea level rise and coastal development. Here we propose a simple model of marsh migration into adjacent uplands and couple it with existing models of seaward edge erosion and vertical soil accretion to explore how ecosystem connectivity influences marsh size and response to sea level rise. We find that marsh loss is nearly inevitable where topographic and anthropogenic barriers limit migration. Where unconstrained by barriers, however, rates of marsh migration are much more sensitive to accelerated sea level rise than rates of edge erosion. This behavior suggests a counterintuitive, natural tendency for marsh expansion with sea level rise and emphasizes the disparity between coastal response to climate change with and without human intervention.

We find that summer methane (CH4) release from seabed sediments west of Svalbard substantially increases CH4 concentrations in the ocean but has limited influence on the atmospheric CH4 levels. Our conclusion stems from complementary measurements at the seafloor, in the ocean, and in the atmosphere from land‐based, ship and aircraft platforms during a summer campaign in 2014. We detected high concentrations of dissolved CH4 in the ocean above the seafloor with a sharp decrease above the pycnocline. Model approaches taking potential CH4 emissions from both dissolved and bubble‐released CH4 from a larger region into account reveal a maximum flux compatible with the observed atmospheric CH4 mixing ratios of 2.4–3.8 nmol m−2 s−1. This is too low to have an impact on the atmospheric summer CH4 budget in the year 2014. Long‐term ocean observatories may shed light on the complex variations of Arctic CH4 cycles throughout the year.
Revised exhumation history of the Wind River Range, WY, and implications for Laramide tectonics
Authors: Stevens Andrea L. , Balgord Elizabeth A. , Carrapa Barbara
Published: April 2016

A reanalysis of apatite fission track (AFT) thermochronology coupled with thermal‐kinetic modeling of samples from the Wind River Range document Late Cretaceous to early Eocene episodic cooling and exhumation of one of the largest basement‐cored ranges in the western United States. Three vertical transects taken at different latitudes along the length of the 145 km Wind River Range reveal that exhumation is uniform along strike suggesting steady displacement along the Wind River Fault, and significant exhumation and relief in the Wind River Range by the early Eocene. Thermal modeling of AFT ages, lengths, and compositional proxies document rapid exhumation from ~65 to 50 Ma. This rapid exhumation episode matches a period of accelerated subsidence in the adjacent Green River and Wind River basins. At ~50 Ma, exhumation dramatically slowed by an order of magnitude coincident with decreasing subsidence in the adjacent basins. No signal of Oligocene cooling is apparent in either AFT cooling ages or thermal modeling suggesting that a possible later phase of reactivation of structures and uplift, as previously suggested, was limited to less than approximately 1 km of exhumation.
The Functions and Longitudinal Outcomes of Adolescents’ Naturally Occurring Mentorships
Authors: Miranda‐Chan Thomas , Fruiht Veronica , Dubon Valeska , Wray‐Lake Laura
Published: April 2016

Adolescence is a time during which positive adults outside the familial context may be most influential to development. A growing body of research on naturally occurring mentors has found favorable outcomes for youth who have these types of positive adult figures in their lives. Less is known, however, about how these naturally occurring mentors influence youths’ development in the long‐term. This study examines the long‐term outcomes related to having a naturally occurring community mentor in adolescence. Results from longitudinal analyses of a nationally representative sample of adolescents revealed that having a mentor in adolescence was related to higher educational attainment, lower criminal activity, higher psychological well‐being (i.e., optimism, self‐efficacy, and lack of depressive symptoms), and greater romantic relationship satisfaction in adulthood. Additionally, a taxonomy of mentoring functions was created from qualitative responses and drawing upon the youth, work, and academic mentoring literature. This taxonomy aims to serve as a framework for understanding the functions of youth mentors to provide a foundation for future research. Implications of findings and future directions are considered.

Protein limitation has been considered a key factor in hypotheses on the evolution of life history and animal communities, suggesting that animals should prioritize protein in their food choice. This contrasts with the limited support that food selection studies have provided for such a priority in nonhuman primates, particularly for folivores. Here, we suggest that this discrepancy can be resolved if folivores only need to select for high protein leaves when average protein concentration in the habitat is low. To test the prediction, we applied meta‐analyses to analyze published and unpublished results of food selection for protein and fiber concentrations from 24 studies (some with multiple species) of folivorous primates. To counter potential methodological flaws, we differentiated between methods analyzing total nitrogen and soluble protein concentrations. We used a meta‐analysis to test for the effect of protein on food selection by primates and found a significant effect of soluble protein concentrations, but a non‐significant effect for total nitrogen. Furthermore, selection for soluble protein was reinforced in forests where protein was less available. Selection for low fiber content was significant but unrelated to the fiber concentrations in representative leaf samples of a given forest. There was no relationship (either negative or positive) between the concentration of protein and fiber in the food or in representative samples of leaves. Overall our study suggests that protein selection is influenced by the protein availability in the environment, explaining the sometimes contradictory results in previous studies on protein selection.

Published: April 2016

Most simple magnesium salts tend to passivate the Mg metal surface too quickly to function as electrolytes for Mg batteries. In the present work, an electroactive salt [Mg(THF)6][AlCl4]2 was synthesized and structurally characterized. The Mg electrolyte based on this simple mononuclear salt showed a high Mg cycling efficiency, good anodic stability (2.5 V vs. Mg), and high ionic conductivity (8.5 mS cm−1). Magnesium/sulfur cells employing the as‐prepared electrolyte exhibited good cycling performance over 20 cycles in the range of 0.3–2.6 V, thus indicating an electrochemically reversible conversion of S to MgS without severe passivation of the Mg metal electrode surface.

Published: April 2016

Increasing the active edge sites of molybdenum disulfide (MoS2) is an efficient strategy to improve the overall activity of MoS2 for the hydrogen‐evolution reaction (HER). Herein, we report a strategy to synthesize the ultrasmall donut‐shaped Cu7S4@MoS2 hetero‐nanoframes with abundant active MoS2 edge sites as alternatives to platinum (Pt) as efficient HER electrocatalysts. These nanoframes demonstrate an ultrahigh activity with 200 mA cm−2 current density at only 206 mV overpotential using a carbon‐rod counter electrode. The finding may provide guidelines for the design and synthesis of efficient and non‐precious chalcogenide nanoframe catalysts.

Published: April 2016

Selective dissolution of hafnium‐peroxo‐sulfate films in aqueous tetramethylammonium hydroxide enables extreme UV lithographic patterning of sub‐10 nm HfO2 structures. Hafnium speciation under these basic conditions (pH>10), however, is unknown, as studies of hafnium aqueous chemistry have been limited to acid. Here, we report synthesis, crystal growth, and structural characterization of the first polynuclear hydroxo hafnium cluster isolated from base, [TMA]6[Hf6(μ‐O2)6(μ‐OH)6(OH)12]⋅38 H2O. The solution behavior of the cluster, including supramolecular assembly via hydrogen bonding is detailed via small‐angle X‐ray scattering (SAXS) and electrospray ionization mass spectrometry (ESI‐MS). The study opens a new chapter in the aqueous chemistry of hafnium, exemplifying the concept of amphoteric clusters and informing a critical process in single‐digit‐nm lithography.

Published: April 2016

Simple quinine as an organocatalyst mediates the addition of various naphthols to halogenated quinones to afford non‐C2‐symmetrical, axially chiral biaryl products, which are promising compounds as chiral ligands and organocatalysts. The rotational barrier required to have two distinct atropisomers has been evaluated in the products generated from the addition of naphthols to various quinones by means of DFT calculations and HPLC. The use of halogenated quinones as reagents was necessary to have configurationally stable enantiomeric products which can be obtained in good yield and stereoselectivity. These compounds have also been prepared in gram quantities and recrystallized to near enantiopurity.

Peripheral Templation Generates an MII6L4 Guest‐Binding Capsule
Authors: Rizzuto Felix J. , Wu Wen‐Yuan , Ronson Tanya K. , Nitschke Jonathan R.
Published: April 2016

Pseudo‐octahedral MII6L4 capsules result from the subcomponent self‐assembly of 2‐formylphenanthroline, threefold‐symmetric triamines, and octahedral metal ions. Whereas neutral tetrahedral guests and most of the anions investigated were observed to bind within the central cavity, tetraphenylborate anions bound on the outside, with one phenyl ring pointing into the cavity. This binding configuration is promoted by the complementary arrangement of the phenyl rings of the intercalated guest between the phenanthroline units of the host. The peripherally bound, rapidly exchanging tetraphenylborate anions were found to template an otherwise inaccessible capsular structure in a manner usually associated with slow‐exchanging, centrally bound agents. Once formed, this cage was able to bind guests in its central cavity.

Published: April 2016

We describe an experimental approach for characterizing the local mechanical behavior of acrylonitrile butadiene styrene (ABS) structures processed through fused deposition modeling. ABS test specimens processed in various build orientations were subject to multiscale mechanical tests as well as local morphology and chemical analyses. Instrumented indentation, local dynamic mechanical analysis, and atomic force microscopy tests were used to explore the mechanical behavior and morphology of build surfaces and weld interfaces. An interfacial stiffening effect was found for the majority of the specimens tested, with up to a 40% increase in the indentation elastic modulus measured with respect to the build surfaces. Raman spectroscopy mapping of the interfacial areas revealed ∼30% less butadiene/styrene and butadiene/acrylonitrile ratios with respect to analysis of the build surfaces. The results provide insight into the multiscale behavior of additive manufactured structures and offer the potential to guide processing–structure–property understanding of these materials. © 2016 Wiley Periodicals, Inc.
