Guanosine‐Quadruplex Hydrogels as Dynamic, Mechanically Tunable and Ion Conductive 3D Scaffolds for Cell Culture Applications

Advanced Functional Materials, EarlyView.
Versatile guanosine‐quadruplex (GQ) hydrogels are developed as dynamic biomatrices for cell culture. These scaffolds are fabricated under mild aqueous conditions, present improved stability, tunable mechanical properties within physiological ranges; fibrillar, porous microstructure, ion conductivity, and cytocompatibility.

Modified Sombor Spectral Radii and Modified Sombor Energies of Splitting and Shadow Graphs

Scientific Annals of Computer Science
Gutman et al. introduced Sombor and Modified Somber index because of the rapidly growing applications in chemistry and network analysis. Graph energy ε(G) and the spectral radius ℘(G) of graph G are essential components that are associated with the ...

Magneto‐Ionic Devices With Polymer‐Based Electrolytes

Advanced Functional Materials, EarlyView.
Polymer electrolytes are introduced for magneto‐ionic devices based on hydroxide and hydrogen ions. The magneto‐ionic effect results in a pronounced voltage‐controlled variation of coercivity in both devices. The switching speed is in the range of 100 ms.

Insulating‐Passivating Interfaces for Narrow‐Bandgap Tin‐Lead Perovskites Enable High‐Photovoltage in Single‐ and Double‐Junction Solar Cells

Advanced Functional Materials, EarlyView.
Combining field‐effect surface passivation of a narrow‐bandgap tin–lead perovskite by diammonium ions with introducing oleyl‐based amphiphiles to create insulating interface layers between the absorber and the adjacent hole and electron transporting layers increases the open‐circuit voltage to 91.5% of the detailed‐balance limit and enhances the power ...

Synergy of sub-nano iridium clusters and cucurbit[6]uril-derived carbon boosts acidic water splitting

Nano Research
Acidic water splitting, essential for sustainable hydrogen production, is limited by the sluggish oxygen evolution reaction (OER). This study presents a series of iridium-based sub-nanocluster electrocatalysts supported on a porous carbon matrix (CBC-Ir ...

Configuration‐Encoded Cell Alignment by Light‐Gated Silicon Photovoltaic Microcell Arrays

Advanced Functional Materials, EarlyView.
Light‐gated silicon photovoltaic microcells convert pulsed illumination into localized electrical cues. Arranging otherwise similar microcells into four‐lobed, six‐lobed, or circular patterns directs fibroblasts into corresponding local arrangements without wired stimulation.

The splitting method and Poincare's theorem: (II) - matrix, polynomial and language [PDF]

Computer Science Journal of Moldova, 2003
This paper is the continuation of the paper which appeared in the previous issue: we revisited Poincare's theorem in the light of the splitting method which was introduced by the author in [5], especially in the geometric aspect of the question. This

Ultra‐Thin Tow‐Based Discontinuous Composites—Material Overview and Aspirations

Advanced Functional Materials, EarlyView.
Tow‐based discontinuous composites made from ultra‐thin tapes offer outstanding in‐plane mechanical properties. This material, inspired by Nacre, has high volume fraction of tapes exceeding 90 % and allows for quasi‐isotropic material plates less than 100 micrometer in thickness.

Ruthenium atomically dispersed in carbon outperforms platinum toward hydrogen evolution in alkaline media

Nature Communications, 2019
Electrochemical water splitting is promising for sustainable energy, but relies on development of electrocatalysts for hydrogen evolution. Here the authors report nitrogen- and ruthenium-codoped carbon nanowires in which ruthenium atoms in a carbon ...
