Transfer Printing and Reconfiguration of Soft Electronics Using Digital Microfluidics and Laser Machining

Advanced Functional Materials, EarlyView.
This paper presents a digital microfluidics‐based technique for transferring and reconfiguring soft nanomembranes. Laser‐machined nanothin membranes are picked up, transported, and aligned via tailored surface tension and the actuation of water droplets, enabling the development of flexible electronics, the integration of functional materials on 3D ...

Impact of charge on traversable wormhole solutions and modified f(R, ϕ) gravity

Nuclear Physics B
In this paper, we investigate the traversable wormhole solutions in the presence of charge within the framework of f(R, ϕ) gravity, where R represents the Ricci scalar and ϕ denotes the scalar potential, respectively.

The Floor‐Ceiling‐Chip, or 2 × 2D = Pseudo‐3D—Approaching 3D Cell Morphology and Organization between Two Opposing 2D Substrates with Cell‐Adhesive Protein Micropatterns

Advanced Healthcare Materials, EarlyView.
Here, we present a novel 3D cell patterning and culture platform. The “Floor‐Ceiling‐Chip” (FC‐Chip) consists of two opposing track‐etched membranes, creating a pseudo‐3D microenvironment for the cells in between. By providing the membranes with micropatterned cell‐adhesive islands of varying geometries and sizes, the FC‐Chip enables control over cell ...

Evolution of a Bianchi Type-V Universe in Modified Gravity: Anisotropy Decay, Energy Conditions and Dark Energy Emergence

International Journal of Scientific Research in Science and Technology
We investigate the evolution of a Bianchi type-V universe within the framework of f(R, T) gravity, incorporating a time-varying cosmological constant and a quadratic equation of state. By employing a specific form of the Hubble parameter, exact solutions to the modified field equations are obtained.

Future of the universe in modified gravitational theories: Approaching to the finite-time future singularity

, 2008
We investigate the future evolution of the dark energy universe in modified gravities including $F(R)$ gravity, string-inspired scalar-Gauss-Bonnet and modified Gauss-Bonnet ones, and ideal fluid with the inhomogeneous equation of state (EoS).

Topology and Material Optimization in Ultra‐Soft Magneto‐Active Structures: Making Advantage of Residual Anisotropies

Advanced Materials, EarlyView.
Residual magnetization induces pronounced mechanical anisotropy in ultra‐soft magnetorheological elastomers, shaping deformation and actuation even without external magnetic fields. This study introduces a computational‐experimental framework integrating magneto‐mechanical coupling into topology optimization for designing soft magnetic actuators with ...
