Deterministic placement of ultra-bright near-infrared color centers in arrays of silicon carbide micropillars

open access: yesBeilstein Journal of Nanotechnology, 2019
We report the enhancement of the optical emission between 850 and 1400 nm of an ensemble of silicon mono-vacancies (VSi), silicon and carbon divacancies (VCVSi), and nitrogen vacancies (NCVSi) in an n-type 4H-SiC array of micropillars.

Structural and biochemical insights into the thermostable esterase Ta0887 from Thermoplasma acidophilum

open access: yesFEBS Open Bio, EarlyView.
In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

Vacancy Formation and Clustering Behavior in δ-MoN: A Systematic Density Functional Theory Study

open access: yesNanomaterials
Molybdenum nitrides are known to have a series of excellent physical properties owing to their unique bonding nature and electronic structure. However, the synthesized samples often exist in nonstoichiometric phases with structural defects (metal or non ...

High‐Resolution MRI Revealed Different Etiology‐Specific Associations With Cerebral Infarction in Adult Moyamoya Vasculopathy

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective High‐resolution MRI enables detailed assessment of intracranial vessel wall pathology in moyamoya vasculopathy. We aimed to classify adult moyamoya vasculopathy etiologies using high‐resolution MRI and to examine subtype‐specific associations between high‐resolution MRI features and ischemic infarction.

Rental Housing and the Natural Vacancy Rate [PDF]

open access: yes
This study uses 1989-2005 data for the Seattle metropolitan area to test the natural vacancy rate hypothesis for rental housing markets using a new methodology. Findings support the existence of a natural vacancy rate for apartments that varies over time,

Exceptionally Durable CO2 Photoreduction Mediated by Defect‐Engineered CaIn2S4 Nanoflowers

open access: yesEcoEnergy
Solar‐driven CO2 reduction faces major limitations due to insufficient photoabsorption, delayed electron‐hole separation, and a significant CO2 activation barrier. Defect engineering was used to optimize these vital processes.

Les évolutions démographiques 1999-2007 de la France métropolitaine : continuités ou ruptures ?

open access: yesEspace populations sociétés, 2011
Since 2004, France adopted a new census method. So, comparing the population of France in 1999 and in 2007 is not pertinent because the figures were calculated according to different census methods.

Early Clinical, Imaging, and Pathological Characteristics of SRPK3/TTN‐Digenic Myopathy

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective SRPK3/TTN‐digenic myopathy was recently established as a skeletal muscle myopathy caused by digenic inheritance. This study characterizes the early clinical presentation of SRPK3/TTN‐digenic myopathy in one previously reported and seven newly identified pediatric patients.

A Model of Vacancy Chains as a Mechanism for Resource Allocation [PDF]

open access: yes
Vacancy chains can be tracked in any context where a the availability of a desirable resource triggers a cascade of occupations through which the scarce resource flows through different owners.
