Spin‐Split Edge States in Metal‐Supported Graphene Nanoislands Obtained by CVD
Advanced Materials, EarlyView.Combining STM measurements and ab‐initio calculations, we show that zig‐zag edges in graphene nanoislands grown on Ni(111) by CVD retrieve their spin‐polarized edge states after intercalation of a few monolayers of Au. ABSTRACT Spin‐split states localized on zigzag edges have been predicted for different free‐standing graphene nanostructures.

Flexoelectrically Induced Polar Topology in Twisted SrTiO3 Membranes
Advanced Materials, EarlyView.Twisted SrTiO3 bilayers host polar vortices of flexoelectric origin, revealed through combined experiment and theory. By reconstructing polarization from the toroidal moment of strain gradients, the work establishes a 3D chiral state with broken inversion and mirror symmetries.

Advanced Materials, EarlyView.The new Cu‐containing MOF (Me2NH2)(CuICl2)@[Cu4(INA)4Cl2O]·1.5dmf (3) contains a cation and an anion as guests and shows UV‐near‐mid‐IR absorption and near‐IR emission. MOF 3 shows gas‐solid reactivity in the presence of NH3 and HCOOH to yield two new 3D MOF.

In the current chapter, we introduce some special methods of summability, viz. the Abel method, the Weighted Mean method, the Euler method and the \((M, \lambda _n)\) or Natarajan method, and study their properties extensively. The connection between the Abel method and the Natarajan method is brought out.

Abstract After having become acquainted in Chapter 2 with several inclusion, comparison and consistency results it is time to put some life into the theory by considering (classes of) examples of summability methods. In this way we shall have the opportunity to apply theorems, proved in Chapter 2, to special matrix methods. In particular,

The summability of a special series by the (C, ?) method
Mathematical Notes of the Academy of Sciences of the USSR, 1976In the paper we study the problem of the summability by the (C,α) method of the special series $$f(x) \sim \sum\nolimits_{n = - \infty }^{n = + \infty } {c_n (x)\exp (in^\mu } (x)),$$ (*) where $$\begin{gathered} c_n (x) = \frac{2}{\pi }\mathop \smallint \nolimits_G f(t)\exp ( - in^\mu (t))\frac{{\sin {\raise0.5ex\hbox{$\scriptstyle 1 ...

The moment constant summability method with specialized weight for the summation of divergent series of the perturbation theory is considered in this work. The method is applied to the calculation of vibrational-rotational energy levels of a two-atom hydrogen molecule. It was tested earlier only on model problems.
