Facile synthesis of SnO2/graphene and Bi–SnO2/graphene-based nanocomposites as electrode materials for energy storage devices

open access: yesResults in Engineering, 2023
Graphene-based nanocomposites are widely investigated as cathode materials for energy storage device. Herein, tin oxide-modified graphene (SnO2/G) and bismuth-doped SnO2/G (Bi–SnO2/G) nanocomposites with nanorod-like morphology were synthesized by the ...

Mitochondrial K+ Transport: Modulation and Functional Consequences

open access: yesMolecules, 2021
The existence of a K+ cycle in mitochondria has been predicted since the development of the chemiosmotic theory and has been shown to be crucial for several cellular phenomena, including regulation of mitochondrial volume and redox state.

Currents and K-functions for Fiber Point Processes [PDF]

open access: yes, 2021
Analysis of images of sets of fibers such as myelin sheaths or skeletal muscles must account for both the spatial distribution of fibers and differences in fiber shape. This necessitates a combination of point process and shape analysis methodology. In this paper, we develop a K-function for fiber-valued point processes by embedding shapes as currents,

Fabrication of palladium/platinum core-shell nanoparticles by electroless metal plating

open access: yesZaštita Materijala, 2018
An electroless metal plating method was used to form metallic platinum (Pt) shells on metallic palladium (Pd) nanoparticles. The electroless metal plating method comprised two steps: (1) reduction of Pd ions to fabricate Pd nanoparticles and (2 ...

K-functionals for Besov spaces

open access: yesJournal of Approximation Theory, 1991
Let \(X_ 0\), \(X_ 1\) be a pair of quasi-normed spaces, which are continuously embedded in a Hausdorff space \(X\); their \(K\)-functional, defined for all \(f\in X_ 0+X_ 1\) is \[ K(f,t):=\inf_{f=f_ 0+f_ 1}(\| f_ 0\|_{X_ 0}+t\| f_ 1\| _{X_ 1}). \] In particular, these functionals provide some information about interpolation spaces generated by \(X_ 0\

On the algebra of $A^k$-functions [PDF]

open access: yesMathematica Bohemica, 2006
Summary: For a domain \(\Omega \subset {\mathbb C}^n\) let \(H(\Omega )\) be the holomorphic functions on \(\Omega \) and for any \(k\in \mathbb N\) let \(A^k(\Omega )=H(\Omega )\cap C^k(\overline {\Omega })\). Denote by \({\mathcal A}_D^k(\Omega )\) the set of functions \(f\: \Omega \to [0,\infty )\) with the property that there exists a sequence of ...
