Evolutionarily divergent DUF4465 domains have a common vitamin B12‐binding function

FEBS Open Bio, EarlyView.
We show that DUF4465 family proteins, widespread across bacteria from gut microbiomes, hydrothermal vents, and soil, share a common vitamin B12‐binding function. These augmented β‐jellyroll proteins bind vitamin B12 via extended loops. Our findings establish sequence‐diverse DUF4465 proteins as a widespread class of B12‐binding proteins, highlighting ...

Hidden progress: broadband plasmonic invisibility

, 2010
The key challenge in current research into electromagnetic cloaking is to achieve invisibility over an extended bandwidth. There has been significant progress towards this using the idea of cloaking by sweeping under the carpet of Li and Pendry, with ...

Feasibility and Tolerability of Performing Portable MRI for Neurological Disorders in an Outpatient Neurology Clinic: A Prospective Cohort

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Accessing brain magnetic resonance imaging (MRI) can be challenging, especially for underserved patients, which may lead to disparities in neurological diagnosis. Method This mixed‐methods study enrolled adults with one of four neurological disorders: mild cognitive impairment or dementia of the Alzheimer type, multiple sclerosis ...

Isotope Effects in Switchable Metal-Hydride Mirrors [PDF]

Physical Review Letters, 1999
Measurements of optical reflectance, transmittance, and electrical resistivity on the switchable mirror systems YHx and YDx show that the absorption of hydrogen induces the same variations as that of deuterium. In both cases there is a weak transparency window for the metallic dihydride (dideuteride) phase and a yellowish transparency in the insulating

[N,N′-Bis(4-chlorobenzylidene)-2,2-dimethylpropane-1,3-diamine-κ2N,N′]iodidocopper(I)

Acta Crystallographica Section E, 2009
The molecule of the title compound, [CuI(C19H20Cl2N2)], lies across a crystallographic mirror plane. The coordination around the copper centre is distorted trigonal planar, with a bite angle of 94.40 (7)°. A six-membered chelate ring is formed

A Thermodynamic 3D Model for the Simulation of Diffusion‐Controlled Alloying Processes in Heterogeneous Material Structures

Advanced Engineering Materials, EarlyView.
A numerical model resulting from irreversible thermodynamics for describing transport processes is introduced, focusing on thermodynamic activity gradients as the actual driving force for diffusion. Implemented in CUDA C++ and using CalPhaD methods for determining the necessary activity data, the model accurately simulates interdiffusion in aluminum ...

Characterisation of metal mirrors on GaAs

Electronics Letters, 1996
The authors describe a Fabry-Perot technique for determining the reflectivity and the phase of the interface between semiconductor and a multilayer metal structure as it will be realised in actual device fabrication. The reflection coefficients of GaAs to Ti/Au, Pd/Au, Au and Ag interfaces are measured at 1.55 /spl mu/m.

Reflection and structural characteristics of semi-bright and mirror bright nickel coatings [PDF]

Journal of the Serbian Chemical Society, 2002
The reflection and structural characteristics of the nickel coatings obtained in the presence of a basic brightening addition agent only, and of both a basic and top brightening addition agent are examined. It is shown that the nickel coating obtained in
