Review of Emergent Gravity [PDF]
openThe idea that gravity may not be a fundamental interaction but rather an emergent phenomenon has gained increasing attention in recent decades. Building on the thermodynamical properties of spacetime horizons, various approaches suggest that Einstein’

Advanced Science, EarlyView.Drop‐location sensitivity remains a key barrier to practical droplet‐based electricity generators (DEGs). Here, a polydimethylsiloxane slippery covalently attached liquid (PDMS‐SCAL)‐coated interface promotes droplet sliding instead of splitting or bouncing, allowing stable electricity generation from randomly falling raindrops. The resulting PDMS‐SCAL‐

Gravitational wave memory in modified gravity theories
reservedAlthough the permanent distortions of spacetime after the passage of gravitational waves, a phenomenon predicted by Einstein’s General Relativity known as the gravitational wave memory effect, have not yet been observed, its detection is expected

Advanced Science, EarlyView.The nanoparticle loading enables effective control over the liquid domain size in bicontinuous interfacially jammed emulsion gels (bijels) produced through solvent‐transfer induced phase separation (STrIPS). The relationship between the nanoparticle loading and domain size profiles in STrIPS bijels is resolved through confocal microscopy and explained ...

Gravity Chains: Estimating Bilateral Trade Flows When Parts And Components Trade Is Important [PDF]
Trade is measured on a gross sales basis while GDP is measured on a net sales basis, i.e. value added. The rapid internationalisation of production in the last two decades has meant that gross trade flows are increasingly unrepresentative of the value ...

Yukawa–Casimir wormholes in the framework of f(R) gravity
European Physical Journal C: Particles and FieldsIn this article, we explore the Yukawa modification of the Casimir wormhole within the framework of f(R) gravity. To accomplish this, we adopt an approach proposed by Garattini (Eur Phys J C 81:824, 2021), wherein the original Casimir source is modified ...

Advanced Science, EarlyView.Morphological anisotropy directs the in vivo transport under physiological flow and clearance of silica nanocarriers. Increasing anisotropy reduces cellular uptake, suppresses hepatic and splenic sequestration, and prolongs systemic circulation by steering particles toward the central flow core.

A Robotic Testing Platform for Pipelined Discovery of Resilient Dielectric Elastomer Actuators
Advanced Science, EarlyView.This work introduces a robotic testing platform enabling high‐throughput, multi‐parameter lifetime mapping of linear dielectric elastomer actuators (DEAs). By integrating programmable high‐voltage control and automated electromechanical measurements, the system identifies material and operating conditions that double actuator lifetime.
