FischerTropsch synthesis: Effect of ammonia in syngas on the FischerTropsch synthesis performance of a precipitated iron catalyst
(Elsevier B.V., 201506)The effect of ammonia in syngas on the FischerTropsch synthesis (FTS) reaction over 100Fe/5.1Si/2.0Cu/3.0K catalyst was studied at 220270 degrees C and 1.3 MPa using a 1L slurry phase reactor. The ammonia added in syngas ... 
FischerTropsch synthesis: Effect of CO conversion on CH4 and oxygenate selectivities over precipitated FeK catalysts
(Elsevier, 20180625)The explanation for CH4 selectivity for iron based FischerTropsch catalysts in the low conversion region (Le., < 50%) remains elusive. In this contribution, the CO conversion effect was carefully examined over four K ... 
FischerTropsch synthesis: Effect of Cu, Mn and Zn addition on activity and product selectivity of cobalt ferrite
(Royal Society of Chemistry, 2016)The effect of Cu, Mn and Zn addition on cobalt ferrite was investigated for FischerTropsch synthesis (FTS). Oxalate coprecipitation followed by decomposition under inert conditions was used to obtain various metal ... 
FischerTropsch Synthesis: Effect of potassium on activity and selectivity for oxide and carbide Fe catalysts
(Springer US, 201311)The effect of potassium on oxides and carbides of iron for FischerTropsch synthesis (FTS) was investigated by pretreating Fe3O4 and Kpromoted Fe catalysts with different gases (H2/H2O and CO). A freshly activated sample ... 
FischerTropsch synthesis: Effects of hydrohalic acids in syngas on a precipitated iron catalyst
(American Chemical Society, 201505)The current investigation was undertaken to identify limits of hydrohalic acid (HX, X = F, Cl, Br) impurities in syngas and shed light on the mechanism of FIX poisoning of a 100 Fe/5.1 Si/2 Cu/3 K FTS catalyst under ... 
FischerTropsch synthesis: Morphology, phase transformation, and carbonlayer growth of ironbased catalysts
(John Wiley & Sons, Inc., 201407)The morphological, phase transformations and carbonlayer growth for unpromoted and Kpromoted iron catalysts were investigated over time during FischerTropsch synthesis. Catalysts were activated in CO for 24 h, which ... 
Fischer–Tropsch synthesis: Mössbauer investigation of iron containing catalysts for hydrogenation of carbon dioxide
(Elsevier, 20120525)CO2 hydrogenation was investigated with a doubly promoted (Cu, K) silica containing iron catalyst. Hägg carbide (χFe5C2) is the dominant phase obtained under CO activation conditions at 543 K and 0.1 MPa and it was stable ... 
Fixed points and determining sets for holomorphic selfmaps of a hyperbolic manifold
(University of Michigan. Dept. of Mathematics, 2007)We study fixed point sets for holomorphic automorphisms (and endomorphisms) on complex manifolds. The main object of our interest is to determine the number and configuration of fixed points that forces an automorphism ... 
A Fornberglike method for the numerical conformal mapping of bounded multiply connected domains
(Wichita State University, 200905)A new Fornberglike method is presented for computing conformal maps from the interior of the unit disk with m1 circular holes to the interior of a smooth closed curve with m1 holes bounded by smooth curves. The method ... 
A Fornberglike method for the numerical conformal mapping of bounded multiply connected domains
(Wichita State University. Graduate School, 20100423)A new Fornberglike method is presented for computing conformal maps from the interior of the unit disk with m>1 circular holes to the interior of a smooth closed curve with m holes bounded by smooth curves. The method is ... 
Forty two problems of first degree from Diophantus’ Arithmetica
(Wichita State University, 201012)This work brings to the audience Diophantus' problems of first degree in a literal word for word English translation from Ver Eecke's French translation of Arithmetica. In addition, these problems are accompanied by ... 
Fortyfold speedup of NV center magnetometry with sequential Bayesian experiment design
(IEEE, 20210501)In magnetometry using quantum defects in diamond (NV  centers), we demonstrate fortyfold speedup with sequential Bayesian experiment design as compared with conventional NVmagnetometry using frequencyswept measurements.

A forward branching phase space generator for hadron colliders
(Springer Berlin Heidelberg, 201810)In this paper we develop a projective phase space generator appropriate for hadron collider geometry. The generator integrates over bremsstrahlung events which project back to a single, fixed Born event. The projection is ... 
From the colormagnitude diagram of omega centauri and (super) asymptotic giant branch stellar models to a galactic plane passage gas purging chemical evolution scenario
(IOP Publishing, 20121001)We have investigated the colormagnitude diagram of omega Centauri and find that the blue main sequence (bMS) can be reproduced only by models that have a helium abundance in the range Y = 0.350.40. To explain the faint ... 
Function spaces
(Springer, 2017)We collect here definitions and known results about space Ck+λ of H¨older continuous functions and about Sobolev space Hkp that we used in the book 
A generalization of ''Existence and behavior of the radial limits of a bounded capillary surface at a corner''
(Pacific Journal of Mathematics, 201802)The principal existence theorem (i.e., Theorem 1) of "Existence and behavior of the radial limits of a bounded capillary surface at a corner" (Pacific J. Math. 176:1 (1996), 165194) is extended to the case of a contact ... 
Geometry of horizontal bundles and connections
(Wichita State University, 201405)An Ehresmann connection on a fiber bundle pi: E > M is defined by prescribing a suitable horizontal subbundle H of the tangent bundle piT: TE > E. For a horizontal bundle to be suitable, it must have a property called ... 
Geometry of nonlinear connections
