This text describes the FD-NU method and its implementation for the BENCHOP-project. 1 Spatial discretizations For example, under the Black-Scholes model European option prices u satisfy the PDE ut(s, t) + 1 2 σsuss(s, t) + rsus(s, t)− ru(s, t) = 0, s > 0, t ∈ [0, T ), (1) where σ and r are the volatility and interest rate, respectively. We employ quadratically refined grids defined by si = [( ...
The premier observation on the enhanced light emission from such a metal-SiO(x)-Si light emitting diode (MOSLED) with Si nano-pyramids at SiO(x)/Si interface is demonstrated at low biases. The Si nano-pyramids exhibits capability in providing the roughness of the SiO(x)/Si interface, and improving the Fowler-Nordheim (F-N) tunneling mechanism based carrier injection through the novel SiO(x)/nan...
Silicon (Si) nutrition may alleviate biotic and abiotic stresses including heavy metal deficiency and toxicity in plants. Iron deficiency and toxicity are important limiting factors in growth of rice. In the present study, role of Si nutrition on alleviation of iron deficiency and toxicity was investigated in rice plants. Plants were cultivated in greenhouse in hydroponics, using Yoshida soluti...
In the title compound, [Ti(C(8)H(13)Si)(C(11)H(21)Si(2))Cl(2)], the Ti(IV) atom is bonded to two Cl atoms, one 1,3-bis-(trimethyl-sil-yl)cyclo-penta-dienyl (Si(2)Cp) and one (trimethyl-sil-yl)cyclo-penta-dienyl ring (SiCp). The Si(2)Cp centroid-titanium distance is 2.0763 (10) Å and the SiCp centroid-titanium distance is 2.0793 (10) Å. The angle subtended at the Ti atom by the centroids of both...
We have investigated the relative stability of a number of p(1×1), c(2×2) and p(2×2) surface reconstructions on the (100) 2 surface as deposited on Si(100). The relative stability of these reconstructions as a function of whether the growth conditions are either Si rich or Co rich is also investigated. We show that the most stable surface under all growth conditions is a c(2×2) reconstructed Si...
Two new neutral hexacoordinated silicon complexes with SiN(4)O(2) (6) and SiN(3)O(2)C (7) coordinating frameworks were synthesized by reaction of the O,N,N,O-donor salen-type ligand 1,2-bis[[(2-hydroxy-4-methoxyphenyl)(phenyl)methylene]amino]ethane (H(2)salen*) with Si(NCS)(4) and HMeSi(NCS)(2), respectively. The complexes 6 [Si(salen*)(NCS)(2)] and 7 [Si(salen*)Me(NCS)] were studied in the sol...
Figure S1: molecules used to chemically functionalize the surfaces. To the left, 3-Aminopropyl)-triethoxysilane (APTES). To the right, poly-L-lysine hydro bromide. Figure S2: Morphological AFM images. Scale bar is 10 µm A: Si/SiO 2 coated with 3-Aminopropyl)-triethoxysilane (APTES), B: Si/SiO 2 coated with, poly-L-lysine hydro bromide and C: Bare Si/SiO 2 .
The title compound, C(40)H(56)Cl(2)Si(4), was synthesized by the coupling of 1,1-di-tert-butyl-1,2-dichloro-2,2-diphenyl-disilane with lithium. The asymmetric unit contains one half-mol-ecule, which is completed by an inversion centre. In the mol-ecule, the tetra-silane skeleton adopts a perfect anti conformation and the Si-Si bonds [2.4355 (5) and 2.4328 (7) Å] are longer than the standard Si-...
The nanoparticles of Ni–Si mixed oxides were prepared by co-precipitation method using nickel nitrate; Ni(NO3)2 6H2O and tetraethylorthosilicate (TEOS). The products were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), and hydrogen temperature program reduction (H2-TPR). The results revealed that Ni–Si mixed oxides particles were obtained with average particle ...
