Ruthenium‐Based Catalysts Supported on Lanthanum and Carbon‐Modified Alumina for Low‐Pressure Ammonia Synthesis

Carbon and Hydrogen, EarlyView.
We proposed a new “hydrogen transfer–desorption” synergistic regulation strategy and developed a Ru/Al2O3‐La‐C catalyst with dual functions. La‐O sites were constructed and carbon components were introduced into the catalyst to regulate the two key steps of hydrogen transfer and desorption on the catalyst surface, respectively, solving the problem of ...

Fermi~I particle acceleration in converging flows mediated by magnetic reconnection

, 2012
Context. Converging flows with strong magnetic fields of different polarity can accelerate particles through magnetic reconnection. If the particle mean free path is longer than the reconnection layer is thick, but much shorter than the entire ...

An Ambient Photocatalytic Approach to In‐Situ Prepare Cobalt/Cobalt Phosphide and Cobalt/Cobalt Phosphide@Graphene Heterojunction Nanomaterials With Optimized Charge Separation Effects for Highly Efficient Relayed Electrocatalytic NOX− Reduction to NH3

Carbon Energy, EarlyView.
A visible‐light‐driven ambient photocatalytic method in‐situ fabricates Co/CoP‐x and Co/CoP@rGO heterojunction with enhanced charge separation, enabling highly efficient relayed electrocatalytic NOx− reduction to NH3 with outstanding Faraday efficiency and ammonia productivity.

Internal properties and environments of dark matter halos

, 2011
We use seven high-resolution $N$-body simulations to study the correlations among different halo properties (assembly time, spin, shape and substructure), and how these halo properties are correlated with the large-scale environment in which halos reside.

CYP2C19 Genotype is Associated with Citalopram Treatment Outcomes in a Real‐World Setting

Clinical Pharmacology &Therapeutics, EarlyView.
CYP2C19 metabolizes various selective serotonin reuptake inhibitors (SSRIs) and genetic CYP2C19 variants are associated with SSRI tolerability and response. Yet, whether CYP2C19 variability also impacts citalopram response remained unclear. We here evaluated associations between CYP2C19 genotypes and citalopram prescription data of 11,079 patients from

Central and Satellite Colors in Galaxy Groups: A Comparison of the Halo Model and SDSS Group Catalogs

, 2008
Current analytic and semi-analytic dark matter halo models distinguish between the central galaxy in a halo and the satellite galaxies in halo substructures.

PharmVar GeneFocus: CYP1A2—Clinical Impact, Genetic Variation, and Updated Nomenclature

Clinical Pharmacology &Therapeutics, EarlyView.
The Pharmacogene Variation Consortium (PharmVar) provides nomenclature for the highly polymorphic human CYP1A2 gene. CYP1A2 plays a crucial role in the biotransformation of several commonly used drugs, including antipsychotics, antidepressants, anxiolytics, and methylxanthines.

Intravenous Lipopolysaccharide Challenge in Healthy Participants Reveals Pharmacodynamic Markers in Blood and Bone Marrow for Early‐Phase Oncology Drug Development

Clinical Pharmacology &Therapeutics, EarlyView.
Demonstrating pharmacological effects in early‐phase oncology clinical trials remains challenging, largely due to the lack of robust pharmacodynamic markers. Lipopolysaccharide (LPS) is used as an immune challenge agent in healthy participants to study drugs for autoimmune conditions.
