New mechanism of plasmons specific for spin-polarized nanoparticles (open access)

New mechanism of plasmons specific for spin-polarized nanoparticles

This article experimentally shows that Co nanoparticles with a single-domain crystal structure support a plasmon resonance at approximately 280 nm with better quality than gold nanoparticle resonance in the visible. The magnetic nature of these nanoparticles suggests a new type of these plasmons.

Evaluation of a Chicken 600K SNP genotyping array in non-model species of grouse (open access)

Evaluation of a Chicken 600K SNP genotyping array in non-model species of grouse

This article tested the cross-species application of the Affymetrix 600K Chicken SNP array in five species of North American prairie grouse (Centrocercus and Tympanuchus genera). This study study provided evidence for successful cross-species application of the chicken SNP array in grouse which diverged ca. 37 mya from the chicken lineage. As far as the authors are concerned, this is the first reported application of a SNP array in non-passerine birds, and it demonstrates the feasibility of using commercial SNP arrays in research on non-model bird species.

Atomic layer deposition of BN as a novel capping barrier for B2O3 (open access)

Atomic layer deposition of BN as a novel capping barrier for B2O3

Article demonstrating in situ deposition of BN by sequential BCl₃/NH₃ reactions at 600 K on two different oxidized boron substrates: (a) B₂O₃ deposited using BCl₃/H₂O ALD on Si at 300 K (“B₂O₃/Si”) and (b) a boron-silicon oxide formed by sequential BCl₃/O₂ reactions at 650 K on SiO₂ followed by annealing to 1000 K (“B-Si-oxide”). The data presented demonstrates that ultrathin BN films deposited by BCl₃/NH₃ ALD are promising candidates for passivation of boron oxide used in shallow doping applications.

Effect of MS222 on Hemostasis in Zebrafish (open access)

Effect of MS222 on Hemostasis in Zebrafish

Article studying the effect of MS222 on hemostasis in Zebrafish. The authors performed various assays and find that Hct values, the amount of blood collected, bleeding, and coagulation differ significantly between anesthetized and nonanesthetized fish. These results suggest that blood collected after MS222 anesthesia of zebrafish has altered hemostasis.

The Arabidopsis PAD4 Lipase-Like Domain Is Sufficient for Resistance to Green Peach Aphid (open access)

The Arabidopsis PAD4 Lipase-Like Domain Is Sufficient for Resistance to Green Peach Aphid

Article exploring PAD4 functions in plant defense by expressing the N-terminal PAD4 lipase-like domain (PAD4ᴸᴸᴰ) without its C-terminal EDS1-PAD4 (EP) domain. The authors show that transgenic expression of PAD4ᴸᴸᴰ in Arabidopsis is sufficient for limiting GPA infestation but not for conferring basal and effector-triggered pathogen immunity. This suggests that the C-terminal PAD4 EP domain is necessary for EDS1-dependent immune functions but is dispensable for aphid resistance. Moreover, PAD4ᴸᴸᴰ is not sufficient to interact with EDS1, indicating the PAD4-EP domain is required for stable heterodimerization. These data provide molecular evidence that PAD4 has domain-specific functions.

Parental stressor exposure simultaneously conveys both adaptive and maladaptive larval phenotypes through epigenetic inheritance in the zebrafish (Danio rerio) (open access)

Parental stressor exposure simultaneously conveys both adaptive and maladaptive larval phenotypes through epigenetic inheritance in the zebrafish (Danio rerio)

This article is a study using crude oil as an example of an environmental stressor in adult zebrafish. The offspring obtained were then assessed for transgenerational epigenetic transfer of oil-induced phenotypes. The authors conclude that epigenetic transgenerational inheritance can lead to an immediate and simultaneous inheritance of both beneficial and maladaptive traits in a large proportion of the F1 larvae. The adaptive responses may help fish populations survive when facing transient environmental stressors.

Sarcoplasmic reticulum Ca²⁺-ATPase (SERCA) activity during the transition to endothermy in an altricial bird

Article describes SERCA activity in the pectoralis muscle and heart ventricle of red-winged blackbird (Agelaius phoeniceus) nestlings, fledglings and adults. Additionally, using a diet manipulation, the authors tested the hypothesis that muscle SERCA activity is affected by dietary fatty acid composition, as has been shown in some previous studies.

UV and infrared absorption spectra and 248 nm photolysis of maleic anhydride (C₄H₂O₃) (open access)

UV and infrared absorption spectra and 248 nm photolysis of maleic anhydride (C₄H₂O₃)

This article investigates maleic anhydride (C₂H₂(CO)₂O, Furan-2,5-dione) that is emitted into or formed in the atmosphere during bio-mass burning events as well as being a photochemical degradation product of some aromatic volatile organic compounds. The photochemical fate of maleic anhydride, however, is presently not well enough characterized to enable modeling of its impact on the environment and human health. In this study, the room temperature UV and infrared absorption spectra of maleic anhydride were measured and quantified using several complementary calibration methods.

Atomic layer deposition of h-BN(0001) multilayers on Ni(111) and chemical vapor deposition of graphene on h-BN(0001)/Ni(111) (open access)

Atomic layer deposition of h-BN(0001) multilayers on Ni(111) and chemical vapor deposition of graphene on h-BN(0001)/Ni(111)

Article studying atomic layer deposition. In situ direct, epitaxial growth of multilayers of hexagonal boron nitride (h-BN) and graphene without physical transfer is of significant interest for the scalable production of graphene/h-BN heterostructures for device applications. Deposition on magnetic substrates is of particular interest for spin tunneling applications. X-ray photoelectron spectroscopy and low energy electron diffraction demonstrate epitaxial atomic-layer deposition (ALD) of multilayer h-BN(0001) on Ni(111) and subsequent deposition of azimuthally-aligned multilayer graphene on h-BN(0001)/Ni(111) by chemical vapor deposition. Boron nitride ALD was accomplished with alternating cycles of BCl₃/NH₃ at a 600 K substrate temperature, and subsequent annealing in ultrahigh vacuum. Subsequent deposition of graphene was achieved by chemical vapor deposition using ethylene (CH₂CH₂) at 1000 K.
