N-doped TiO2 coatings grown by atmospheric pressure MOCVD for visible light-induced photocatalytic activity [PDF]

open access: yes, 2007
N-doped TiO2 films were deposited by atmospheric pressure CVD from titanium tetra-isopropoxide (TTIP) and N2H4 as reactive gas in the temperature range 400–500 °C on various substrates.

Horizontal and vertical structure of reactive bromine events probed by bromine monoxide MAX-DOAS [PDF]

open access: yesAtmospheric Chemistry and Physics, 2017
Heterogeneous photochemistry converts bromide (Br−) to reactive bromine species (Br atoms and bromine monoxide, BrO) that dominate Arctic springtime chemistry.

REACTIVE PREFERENTIAL STRUCTURES AND NONMONOTONIC CONSEQUENCE [PDF]

open access: yesThe Review of Symbolic Logic, 2009
We introduce Information Bearing Relation Systems (IBRS) as an abstraction of many logical systems. These are networks with arrows recursively leading to other arrows etc. We then define a general semantics for IBRS, and show that a special case of IBRS generalizes in a very natural way preferential semantics and solves open representation problems for

The Effect of Deposition Parameters on the Structure and Mechanical Properties of Chromium Oxide Coatings Deposited by Reactive Magnetron Sputtering

open access: yes, 2018
Appropriate conditions for depositing hard Cr2O3 coatings by reactive sputtering techniques have yet to be defined. To fill this gap, the effect of principal deposition parameters, including deposition pressure, temperature, Cr-target voltage, and Ar/O2 ...

Crystal structure induced residue formation on 4H-SiC by reactive ion etching

open access: yesAIP Advances, 2016
The (000 1 ¯ ) C face of 4H-SiC wafer was etched by reactive ion etching in SF6/O2 plasma. The effect of etching

Inferring epitopes of a polymorphic antigen amidst broadly cross-reactive antibodies using protein microarrays: a study of OspC proteins of Borrelia burgdorferi. [PDF]

open access: yesPLoS ONE, 2013
Epitope mapping studies aim to identify the binding sites of antibody-antigen interactions to enhance the development of vaccines, diagnostics and immunotherapeutic compounds. However, mapping is a laborious process employing time- and resource-consuming

Structure–property-reactivity studies on dithiaphospholes [PDF]

open access: yesDalton Transactions, 2019
The crystal structures of P-halo-1,2,3-dithiaphospholes and the reduced P–P coupled dimer are reported. Treatment with Lewis acids affords phosphenium cations which are shown to be active catalysts for hydroboration reactions.

The fractality of the relaxation modes in deterministic reaction-diffusion systems

open access: yes, 2002
In chaotic reaction-diffusion systems with two degrees of freedom, the modes governing the exponential relaxation to the thermodynamic equilibrium present a fractal structure which can be characterized by a Hausdorff dimension. For long wavelength modes,

Metamaterial inspired electromagnetic bandgap filter for ultra-wide stopband screening devices of electromagnetic interference

open access: yesScientific Reports, 2023
Presented here is a reactively loaded microstrip transmission line that exhibit an ultra-wide bandgap. The reactive loading is periodically distributed along the transmission line, which is electromagnetically coupled.

Design and control of parallel three phase voltage source Inverters in low voltage AC microgrid [PDF]

open access: yes, 2017
Design and hierarchical control of three phase parallel Voltage Source Inverters are developed in this paper. The control scheme is based on synchronous reference frame and consists of primary and secondary control levels. The primary control consists of
