An Implication of Ether Drift [PDF]
arXiv, 1998 The experimental results of the two-photon absorption(TPA) and M\"{o}ssbauer-rotor(MR) for testing the isotropy of the speed of light are explained in an ether drift model with a drift velocity of $\sim 10^{-3}c$. Further tests of the ether drift assumption are suggested.

Ipso-Borylation of Aryl Ethers via Ni-Catalyzed C-OMe Cleavage.
Journal of the American Chemical Society, 2015 A Ni-catalyzed ipso-borylation of aryl ethers via C(sp(2))-OMe and C(sp(3))-OMe cleavage is described. The transformation is characterized by its wide substrate scope under mild conditions and an exquisite divergence in site selectivity that can be ...

Astronomical aberration in the theory of ether and the theory of relativity. A new original interpretation [PDF]
arXiv, 2009 A new interpretation of astronomical aberration is given in this paper and it is based on the new theory of reference frames. The new interpretation confirms the result of classical physics based on the concept of ether and does not confirm the result of Special Relativity based on the constancy of the speed of light.

Shape‐Stabilization of Phase Change Materials with Carbon‐Conscious Poly(hydroxy)Urethane Foams
Advanced Functional Materials, EarlyView.Poly(hydroxy)urethane (PHU) foam, derivable from carbon dioxide (CO2) and bio‐based resources, is a promising material platform for shape‐stabilizing phase change materials (PCMs). We demonstrate the encapsulation of both paraffins and calcium chloride hexahydrate in PHU foam, achieving 48 stable thermal cycles by introducing 5 wt.% barium carbonate ...

arXiv, 2000 The paper is an introduction into General Ether Theory (GET). We start with few assumptions about an universal ``ether'' in a Newtonian space-time which fulfils \partial_t \rho + \partial_i (\rho v^i) = 0 \partial_t (\rho v^j) + \partial_i(\rho v^i v^j + p^{ij}) = 0 For an ``effective metric'' $g_{\mu\nu}$ we derive a Lagrangian where the ...

Advanced Functional Materials, EarlyView.The relationship between primary polymer structure and pattern quality in the directed self‐assembly of chemically modified polystyrene‐block‐poly(methyl methacrylate) derivatives is explored. The perpendicular lamellae are aligned, with a periodicity below 20 nm. No parallel orientations or dislocations form, and line patterns are well defined over an
